    In this study, the prevalence of psychoactive substance use and dependence was estimated among students at a Spanish university, together with associated factors, polyconsumption, and comorbidity with depression, using a 554-member sample stratified by sex, degree year, and discipline. 86.5% had consumed some potentially addictive psychoactive substance in the past month, and 10.5% satisfied DSM-IV criteria for dependence on nicotine, alcohol, caffeine, or cannabis. Polyconsumers (90.4%) consumed an average 3.2 different substances. Current depression implied increased likelihood of having consumed tobacco or psychoactive pharmaceutical drugs in the past month, and DSM-IV symptoms of major depressive episode were shown by 8.6% of 58 substance-dependent participants, 8.7% of 540 past-month legal substance consumers, and 12.1% of 140 past-month illegal substance consumers.

    Full Text Available The addiction to psychoactive drugs still remains among the relevant research topics. The research herein focuses on the study and analysis of the relations among the alexithymia, and personality styles. The analyses of such psychological constructs may represent valuable views beneficial for the progress in the up-to-date addictology. The article deals with a number of topics, such as, definition of alexithymia, the issue of addictology and personality aspects.. The applied statistical methods are descriptive statistics, factor analysis, non-parametric Spearman's correlation analysis and Mann-Whitney U Test. The reason for choosing the non-parametric statistics has been the conclusion of the normality test pointing at the fact that the acquired data had not complied with the normal distribution assumption. The data collection methods were questionnaires TAS-20 (Toronto Alexithymia Scale to measure alexithymia, and PSSI (Personality Style and Disorder Inventory. The gross sample under research was represented by 55 probands, namely 14 women and 41 men. The data were collected in the Psychiatric Hospital of Marianna Oranžská in Bílá Voda. The obtained results enabled us to answer the postulated research questions, which were evaluated and the following conclusions were reached: In people addicted to alcohol alexithymia occurs in 41.83 %. In subjects addicted to psychoactive drugs with alexithymia there is a substantial difference in the personality styles of a schizoid, obsessive-compulsive, avoidant, negativistic, borderline, histrionic, and self-defeating type. We believe that in this field of research there is still a huge gap to be filled, and we hope that the research may help to do so by enriching the knowledge with concrete results.

    Full Text Available Introduction: The use of psychoactive substances by the student population has been the object of various studies in Brazil. Objective: To determine the prevalence of substance use among students. Methods: Quantitative study with a closed questionnaire based on standardized assessment instruments was developed. It consists of questions related to types of psychoactive substance use, abuse, frequency and duration of use, self-criticism regarding the use, consequences of use in relation to health, and misdemeanors committed under the influence of psychoactive substances. The sample included the participation of 268 students. A total of 183 (68.3% questionnaires were analyzed, and only those with positive result for substance abuse at some point in life, the remainder, 85 (31% questionnaires, had negative responses to psychoactive substances. Results: Students’ responses to the two years surveyed indicated that the first psychoactive substance used was alcohol (77.9%, followed by tobacco use (10.9%, and marijuana (7.6%. Of the students surveyed, 145 (79.2% answered that still make use of psychoactive substances, and the current frequency of use varies from one or more times per week. When asked about the possibility of being or becoming drug addicts, 169 (92.3% responded that they are not or will not become dependent. Conclusion: The results indicate the high rate of substance use among college students surveyed, and point to their contradiction to consider such psychoactive substances harmful to their health.

    Emerging drugs of abuse, belonging to many different chemical classes, are attracting users with promises of "legal" highs and easy access via internet. Prevalence of their consumption and abuse through wastewater-based epidemiology can only be realized if a suitable analytical screening procedure exists to detect and quantify them in water. Solid-phase extraction and ultra-high performance liquid chromatography quadrupole time-of-flight-mass spectrometry (UHPLC-QqTOF-MS/MS) was applied for rapid suspect screening as well as for the quantitative determination of 42 illicit drugs and metabolites in water. Using this platform, we were able to identify amphetamines, tryptamines, piperazines, pyrrolidinophenones, arylcyclohexylamines, cocainics, opioids and cannabinoids. Additionally, paracetamol, carbamazepine, ibersartan, valsartan, sulfamethoxazole, terbumeton, diuron, etc. (including degradation products as 3-hydroxy carbamazepine or deethylterbuthylazine) were detected. This method encompasses easy sample preparation and rapid identification of psychoactive drugs against a database that cover more than 2000 compounds that ionized in positive mode, and possibility to identify metabolites and degradation products as well as unknown compounds. The method for river water, influent and effluents samples was fully validated for the target psychoactive substances including assessment of matrix effects (-88-67.8%), recovery (42-115%), precision (psychoactive drugs biomarkers and other water contaminants is demonstrated.

    The aim of this study was to identify profiles of psychoactive substances consumers among workers according to their professional characteristics. In 2006, 2213 workers participated in "Mode de Vie et Travail" (Drugs and Work) cross-sectional survey. Data were collected by a self-administered questionnaire concerning general and professional characteristics and the consumption of psychoactive substances (psychoactive drugs, tobacco, alcohol and cannabis) during the professional medical visit. We identified consumer profiles with a hierarchical ascendant classification as statistical method. We underlined five profiles associated with psychoactive substance consumption: (1) alcohol consumers in the workplace were sales engineers satisfied with their employment, (2) alcohol consumers after their work were not satisfied with their lives, (3) cannabis consumers were men professionally satisfied but suffering from job insecurity, (4) smokers were workers with professional responsibilities under time pressure, and finally (5) poly-consumers had strong professional constraints. This study guides occupational physicians on psychoactive substances consumption among a worker population. © 2011 Société Française de Pharmacologie et de Thérapeutique.

    The consumption of psycho-active substances (PAS) by pregnant women is in a growing increase around the world. It is a major problem of public health in some countries due to serious and negative consequences for children and society as well as for pregnant women. This problem has also increased among women in Morocco. However, it is still neglected and underrated in the absence of any official statistical data. This is the first study leading to a better profiling of pregnant women who may consume psycho-active substances during their pregnancy; it would permit better medical and psychosocial care of both women and children. To determine the prevalence and the factors associated with the psycho-active substances used by pregnant women and describe their socio-demographic characteristics. A trans-sectional study was carried out from September to October 2010, including pregnant women consulting at the obstetrical service of the provincial hospital Moulay Abdellah in the city of Salé. The study included women who were pregnant or had recently given birth, and not having any serious mental disorders that could have upset their cognitive abilities. The data was collected through a straight questionnaire of 25 items specifying the socio-demographic characteristics, data about pregnancy and habits of using psycho-active substances. One hundred and fifty pregnant women were included in the study. The majority of them (83.2%) were aged 20 to 40 years old, 94.6% were married, 96% were unemployed and depended on their spouses for their financial resources and 80% had normal domestic relationships (from average to good quality). Among the women, 31.3% of them reported traumatic events in the past. The prevalence of psycho-active substance consumption by the pregnant women of our sample was 11.3%. The used substances were tobacco (9.3%) and cannabis (4%). These women were more likely to have a low level of education (47.1 vs 16.5). They were victims of abuse or neglect in

    Psychoactive substances take on many symbolic meanings, and thus the politics of psychoactive substances has featured symbolic elements, or value-based rationality, alongside and often dominating instrumental rationality. Drawing particularly on the work of Joseph Gusfield and Nordic scholars, the chapter considers the symbolic dimension in the politics of substance use, even in Nordic countries celebrated for their societal commitment to knowledge-based policymaking, and its effects on the interplay of science and policy.

    To determine the family type, family structure in a group of patients with a diagnosis of substance abuse or dependence who were at a rehabilitation center for addiction during the period between August and October 2009. Through a descriptive qualitative-interpretative methodology 10 patients who met inclusion criteria for substance dependence or abuse were studied. The fieldwork and transcripts were made for three months by non-participant observation, non-structured interviews and examination of patients' clinical history. Seven of the families interviewed were single-parent families with an unconventional organization on "gender roles". Single-parent families favored loneliness, difficulty in rule-setting, de-idealization of the place of the father in the family structure and a constant search for complicity. In the analysis by categories, we found that in 10 families in the study of individuals with addictions it is common to find family structure characteristics such as inadequate communication, lack of authority rules and limits, presence of triangulations, the lack of cohesion due to the existence of a disconnected relationship pattern and changed roles compared to conventional gender. The search for the affection of the mother at her emotional overload absence of roles and lack of father, raised by the separation of the couple, was found as an essential aspect underlying the addictive behavior. A pattern of parental abandonment is configured. The findings confirmed what has been mentioned by various authors regarding the characteristics of the family typology structure and personal factors in patients with addictions, in addition to their need for affection combined with the desire for the mother's presence. The family typology does not determine for itself the abuse of psychoactive substances, but the influence of other factors such as family structure, especially deficient affective interactions, which should be considered in the development of

    All around the world, the potential consequences of the increasing use of psychoactive substances during pregnancy are a major public health concern. It is estimated that 20 to 30% of pregnant women use tobacco, 15% use alcohol, 3 to 10% use cannabis and 0.5 to 3% use cocaine. The estimation of tobacco consumption during pregnancy is better known as compared with alcohol and substance use prevalence during pregnancy, which remains under estimated or unknown. For example, in France, the prevalence of cannabis and cocaine use during pregnancy is unknown. In general, the prevalence of drug or alcohol use during pregnancy is estimated by extrapolating data from epidemiological studies conducted in the general population (in France or in other countries). However, drug or alcohol use in the general population may dramatically vary from one country to another. Even if some studies have reported the prevalence of alcohol or substance use in different countries around the world, most of them were based on the mother's interview. In most cases, the mother did not report exactly the amount of drugs or alcohol used. Further studies measuring alcohol or substance use in the mother's blood, hair or in the newborn's meconium are needed. In addition, different methodologies have been used in the literature (different types of interview, with or without biological measurements; different subjects included (in- or out-pregnant women, psychiatric comorbidities or not, different economic status, etc). Despite these methodological biases, the prevalence of drug or alcohol use increases in pregnant women, and in most cases, several drugs are associated. Most of the studies have used structured or semi-structured interviews such as the addiction severity index (ASI) or the alcohol use disorders identification test (AUDIT) to assess alcohol or drug consumption. In addition, the identification of risk factors for substance or alcohol use during pregnancy would allow the early detection of

    The aim of this study was to summarise the scientific evidence on the prevalence of psychoactive substance use and on the factors associated with their intake among truck drivers. A systematic review was performed in the databases PubMed, Scientific Electronic Library Online, Latin American and Caribbean Health Sciences, and Cochrane and 36 cross-sectional studies were identified with quantitative results about the use of psychoactive substances by truck drivers. Out of these, 28 were carried out in countries with large land areas and 23 obtained their information through self-reporting. The most frequently studied substances were alcohol (n=25), amphetamines (n=17), marijuana (n=16) and cocaine (n=13). The prevalence of the use of these substances greatly varied: alcohol (0.1-91.0%); amphetamines (0.2-82.5%), marijuana (0.2-29.9%), cocaine (0.1-8.3%). The frequency of substance use was lower in studies that investigated the presence of these substances in biological samples than in those based on self-reported use. In 12 studies that evaluated factors associated with the intake of psychoactive substances, the following stood out: younger age, higher income, longer trips, alcohol consumption, driving in the night shift, travelling interstate routes, long or short sleep, fewer hours of rest, little experience of the driver, connection with small and medium sized companies, income below levels determined by labour agreements, productivity-based earnings and prior involvement in accidents. The frequency of psychoactive substance use by truck drivers seems to be high, although that greatly varies according to the type of substance and the method of collecting the information. The use of these substances was mainly associated with indicators of poor working conditions.

    In humans, some psychotropic agents (alcohol, drugs, illicit substances) have been suggested to play a role in the occurrence of major behavioural disorders, mainly due to the suppression of psychomotor inhibition. Behavioural disinhibition is a physiological mechanism which allows humans to behave appropriately according to a given environmental situation. The behavioural disinhibition induced by either therapeutic dosage or misuse involves the loss of restraint over certain types of social behaviour and may increase the risk of auto or hetero-aggression and acting out. The increased use of psychotropic agents in recent years and the occurrence of unwanted effects are worrying and must be detected and evaluated. The objective of the present study was to establish a causal relationship between psychoactive substance use and occurrence of major behavioural disorders, such as paradoxical rage reactions and suicidal behaviour, based on a literature analysis. It consisted of reviewing reports of drug-induced violent reactions in healthy volunteers and demonstrating, where possible, a cause-effect relationship. Patients with schizophrenia and psychopathic personalities were not included in our study since psychiatric comorbidity could influence behavioural responses. Psychotropic agents included drugs, licit and illicit substances already associated with violence in the past. Many reports used the "Go/No Go test" to evaluate the disinhibiting effect of psychotropic substances; this allows the "cognitive mapping" of drugs. The results suggest that only alcohol, antidepressants, benzodiazepines and cocaïne are related to aggressive behaviour. The best known precipitant of behavioural disinhibition is alcohol, which induces aggressive behaviour. However, there are large differences between individuals, and attentional mechanisms are now recognised as being important in mediating the effects of alcohol. Suicidal tendency as an adverse antidepressant reaction is rare

    Full Text Available The consumption of psychoactive substances has followed Humanity since the primordial of the civilization, not only by their medicinal proprieties as well as for religious and recreational purposes, however, its usage creates dependence and, subsequently, illicit traffic. Since the beginning of the previous century, many nations and international organisms have worked, without success, in the development of elimination strategies to this problem. Part of this failure is due to the current legal forms, because, when a new psychoactive substance is created, it occupies a legal void, in which its’ distribution and consumption are free, being recurrent updates to the legislation needed. An example of this situation was the one verified in the establishments commonly called smartshops. We purpose to compile the psychoactive substances’ legislation, analyse its’, advantages and disadvantages and to suggest a new legal form, based in new scientific facts, that allows to contour this situation.

  10. Separation of enantiomers of new psychoactive substances by high-performance liquid chromatography.

    2018-03-01

    New psychoactive substances are defined as compounds with consciousness-changing effects and have been developed simultaneously with classical drugs. They arise through structural modifications of illegal substances and are mainly produced to circumvent laws. Availability is simple, since new psychoactive substances can be purchased from the Internet. Among them many chemical drug compound classes are chiral and thus the two resulting enantiomers can differ in their effects. The aim of this study is to develop a suitable chiral high-performance liquid chromatography separation method for a broad spectrum of new psychoactive substances using cellulose tris(3,5-dichlorophenylcarbamate) as a chiral selector. Experiments were performed by high-performance liquid chromatography in normal-phase mode under isocratic conditions using ultraviolet detection. Direct separation was carried out on a high-performance liquid chromatography column (Lux® i-Cellulose-5, 3.5 μm, Phenomenex®), available since 2016. Excellent separation results were obtained for cathinones. After further optimization, even 47 instead of 39 out of 52 cathinones showed baseline separation. For amphetamine derivatives, satisfactory results were not achieved. Further, new psychoactive substances from other compound classes such as benzofuranes, thiophenes, phenidines, phenidates, morpholines, and ketamines were partially resolved, depending on the polarity and degree of substitution. All analytes, which were mainly purchased from the Internet, were proven to be traded as racemates. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Full Text Available The purpose of this study was to evaluate the effectiveness of a succinic acid derivate, a substrate metabolic agent cytoflavin in patients with acute poisoning with synthetic psychoactive drugs.Materials and methods. A retrospective evaluation of effectiveness of a combined intensive care treatment protocol for 622 patients with acute narcotic poisoning (methadone and synthetic cannabinoids was carried out. All patients were divided into two groups. The main group (112 patients, median age 38.2±12.0 years included patients who, in addition to the basic treatment, received cytoflavin by intravenous drop infusion, 20–40 ml diluted in 400–500 ml of 10% glucose, for 5 days. Patients of the reference group (510 subjects, median age 37.6±14.1 years received treatment according to the «classical scheme». In addition to conventional examination, all patients underwent duplex scanning of cerebral vessels, examination of changes in the cerebral blood circulation and electroencephalogram findings. The severity of somatic disorders was assessed using criteria of the Glasgow coma scale. The severity of the asthenic syndrome was assessed according to the MFI-20 scale.Results. Compared to patients who received a standard therapy, patients of the main group had a significantly more rapid recovery from coma (by 1.5-fold: 23.5±3.1 days, versus 15.1±3.0 days, respectively, P0.05; the duration of psychotic disorders was shorter (by 1.8-fold: 15.5±4.2 hours vs 8.3±2.5 hours., respectively, P0.05, and the intensity of asthenic syndrome (by 2.8-fold: 64.1±3.3 rel. units vs 23.0±4,9 rel. units, respectively, P0.05 was also lower.Conclusion. Inclusion of cytoflavin in a protocol of a complex treatment of patients with synthetic drugs poisoning increased the effectiveness of the therapy. Data demonstrate that inclusion of the drug can be recommended for treatment of acute synthetic narcotic poisoning.

    Psychoactive substance use has often been claimed to help generate and facilitate the artistic creative process. This study explored the role of artists' substance use in their creative processes and their efforts to balance between enhancement and relaxation. Semistructured interviews concerning the artistic creative process and the role of psychoactive substance use were recorded with 72 artists and analyzed using content analysis. The participants were classified according to their substance use in three groups (Cannabis Group, Alcohol Group, and Control Group). Results show that both alcohol and cannabis were used to facilitate creativity and the emotional states that are necessary for the artistic creative process. Participants in the Control group reported that listening to music might function as a mind-altering tool. It was also found that for some artists, substance use is not only characteristic to creation, but it is also part of their everyday lives. Artists are aware of the balancing phenomenon during the artistic creative process. Whether psychoactive substance(s) or other environmental stimuli (such as music) are used to reach the required effect appears to depend upon the individual.

    Novel psychoactive substances are increasingly available, both in traditional storefronts and via the Internet. While some use of such substances has been captured in Australian consumer surveys and wastewater analyses, there is little information about the products that are available to Australia via the Internet. Systematic monthly Internet monitoring for emerging psychoactive substances was conducted between July 2011 and July 2012. Webstores identified through searches were examined to determine if they sold stimulant or psychedelic emerging psychoactive substances to Australia. Internet search numbers for these products were examined over time using commercial tools. In 12 months, 43 unique webstores were identified selling to Australia, averaging two new webstores per month; however, two-fifths had closed within six months. Over 200 unique chemically unspecified products sold by purported effect (e.g. 'charge') were identified over 12 months, averaging 10 new products per month. Almost half of these products had disappeared from the market within six months. Eighty-six unique chemically specified products (e.g. methylenedioxypyrovalerone) were identified over 12 months, averaging four new novel substances per month. Once released, these products typically remained available, with almost 90% still available for purchase over a 6-month period. Almost 40 000 searches for these products emanated from Australia per month. This market is fast paced as retailers strive to beat both regulatory processes and competitors. Ongoing attention to these markets, incorporating surveillance of both Internet and traditional storefronts, is crucial as several of the substances identified have demonstrated potential for health and neurological harm. © 2013 Australasian Professional Society on Alcohol and other Drugs.

    Recreational drugs (illicit drugs, human and veterinary medicines, legal highs, etc.) often contain lacing agents and adulterants which are not related to the main active ingredient. Serious side effects and even the death of the consumer have been related to the consumption of mixtures of psychoactive substances and/or adulterants, so it is important to know the actual composition of recreational drugs. In this work, a method based on flow injection analysis (FIA) coupled with high-resolution mass spectrometry (HRMS) is proposed for the fast identification of psychoactive substances in recreational drugs and legal highs. The FIA and HRMS working conditions were optimized in order to detect a wide range of psychoactive compounds. As most of the psychoactive substances are acid-base compounds, methanol-0.1 % aqueous formic acid (1:1 v/v) as a carrier solvent and electrospray in both positive ion mode and negative ion mode were used. Two data acquisition modes, full scan at high mass resolution (HRMS) and data-dependent tandem mass spectrometry (ddMS/HRMS) with a quadrupole-Orbitrap mass analyzer were used, resulting in sufficient selectivity for identification of the components of the samples. A custom-made database containing over 450 substances, including psychoactive compounds and common adulterants, was built to perform a high-throughput target and suspect screening. Moreover, online accurate mass databases and mass fragmenter software were used to identify unknowns. Some examples, selected among the analyzed samples of recreational drugs and legal highs using the FIA-HRMS(ddMS/HRMS) method developed, are discussed to illustrate the screening strategy used in this study. The results showed that many of the analyzed samples were adulterated, and in some cases the sample composition did not match that of the supposed marketed substance.

    A man in his twenties who had no previous history of violence, snorted large quantities of two substances he identified as 3-methoxyphencyclidine (3-MeO-PCP), and methylenedioxypyrovalerone (MDPV); both are recognised as novel psychoactive substances, or commonly described in the media as "legal highs". He also inhaled butane gas. He experienced vivid hallucinations and developed bizarre ideas. During this state of mind he stabbed his father multiple times and was arrested and charged with attempted murder. He had a previous history of drug induced psychosis and although he had some slight residual symptoms before he consumed the substances, these were not considered relevant to his criminal liability at the time of the offence. The hallucinations caused by the use of these substances took six weeks to completely recede. He was convicted of attempted murder and sentenced to four years in prison.

    Full Text Available New psychoactive substances (NPS are defined as substances of abuse, either in a pure form or a preparation, that are not controlled by the 1961 Single Convention on Narcotic Drugs or the 1971 Convention on Psychotropic Substances, but which may pose a public health threat. In this context, the term “new” does not necessarily refer to new inventions but to substances that have recently become available or popular in a given society or country. This definition indicates that the problem of NPS is not new; however, the availability of any information via new communication technologies in the 21st century has enabled the spread of unwanted and socially harmful information, like information on the commercial availability of various NPS, offered in rising amounts and brands.

    Full Text Available ABSTRACT OBJECTIVE To analyze the prevalence of exposure to psychoactive substances in public students of basic education and its association with sociodemographic characteristics. METHODS This is a cross-sectional survey conducted from March to September 2015, involving 1,009 students of the basic and high school education in 20 public schools in the municipality of Aracaju, State of Sergipe, Brazil. The data have been compiled using questionnaires previously applied in national studies of the Brazilian Center for Psychotropic Drugs. The variables have been dichotomized for later logistic regression using the Chi-square test to analyze associations between experimentation with psychoactive substances and other sociodemographic variables; odds ratio and confidence intervals have also been calculated. The level of significance adopted was 5%. RESULTS We have identified that 69.6% of the students have experimented alcohol and 12.4% cigarettes. Age (≥ 15 years has shown a significant association with experimentation with alcohol (p < 0.001 and cigarettes (p = 0.02, acting as risk factor in both cases (OR = 2.34 and 1, 78, respectively, but it acted as a protective factor for the use of inhalants (p = 0.03 and OR = 0.58 and weight loss medication (p = 0.006 and OR = 0.44. Religious practice had a significant association with experimentation with alcohol (p = 0.01, functioning as a protective factor (OR = 0.56. CONCLUSIONS We have concluded that the psychoactive substance most experienced by students was alcohol, followed by cigarettes, and chance for experimentation increases after the age of 15. Religious practice, in turn, acts as a protective factor for experimentation with alcohol.

    The analysis of substances of abuse remains one of the most matured areas in forensic science with a strong scientific basis, namely analytical chemistry. The current evolving drug markets, characterized by the global emergence of new psychoactive substances (NPS) and the need for forensic scientists to identify an unprecedented and ever-increasing number of NPS, presents a unique challenge to this discipline. This article looks at the current situation with NPS at the global level, and the challenges posed to the otherwise technically robust forensic science discipline of analysis of substances of abuse. It discusses the preparedness of forensic science to deal with the current situation and identifies the need for a shift in forensic science practice, especially one which embraces research and looks beyond normal casework in order to provide the much needed data for developing effective policy responses to the NPS problem. © 2015 The Author(s) Published by the Royal Society.

    2015-01-01

    During the last decade, there has been an increase in the availability and use of novel psychoactive substances (NPS), also known as "legal highs," across the world. They include a wide range of products, from natural plant-originated substances to synthetic compounds, that can be purchased both online and from high street retailers. "Legal highs" mimic psychoactive effects of illicit drugs of abuse. However, they are claimed to consist of compounds that are legal to sell, possess, and use, often labeled as "not for human consumption" to circumvent drug abuse legislation. Based on the spectrum of their actions on cognitive processes, mood, and behavior, "legal highs" can be classified into four basis categories: amphetamine- and ecstasy-like stimulants, synthetic cannabinoids (SCs), hallucinogenic/dissociative, and opioid-like compounds. NPS may, however, exhibit a combination of these actions due to their designed chemical structure. Although the prevalence and pattern of NPS use differ between various countries, the most popular groups are SCs and psychostimulants, described in this chapter. Currently, there is limited information available on the potential acute toxicity (harms) associated with the use of these substances. However, the number of intoxicated people presenting with emergencies is constantly increasing, providing evidence that negative health and social consequences may indeed seriously affect recreational and chronic users. © 2015 Elsevier Inc.

  5. The Growing Problem of New Psychoactive Substances (NPS).

    Science.gov (United States)

    Madras, Bertha K

    The term "new psychoactive substances" (NPS) can be defined as individual drugs in pure form or in complex preparations that are not scheduled under the Single Convention on Narcotic Drugs (1961) or the Convention on Psychotropic Substances (1971). NPS may be categorized by chemical structure, by psychoactive properties, by biological targets, or by source (plant, synthetic, or combined). The emergence of hundreds of NPS in the past decade is challenging for public health and drug policies globally. The novelty of NPS, their ambiguous legal status, ability to evade toxicological tests, swift adaptation to legal restrictions, global Internet marketing, and scant public knowledge of their adverse effects are among the key drivers of this twenty-first century phenomenon. Multi-disciplinary research in areas of biology, epidemiology, prevention, and web analytics are needed to develop effective responses in a domain capable of overwhelming current international conventions and national drug control policies. Ultimately, research-guided prevention education will fortify societies against this tidal wave.

    Full Text Available Plant-based drugs of abuse are as old as recorded human history. Although traditional addictive substances, such as opium, cannabis and coca, have been controlled by the United Nations anti-drug conventions, many, if not most, natural plants with addictive or abuse liability remain elusive. Therefore, the United Nations Office on Drugs and Crime (UNODC has warned the emerging threat from new psychoactive substances (NPS, which are mostly derived or modified from the constituents of natural origin. For example, synthetic cannabinoids and synthetic cathinones are derived from the cannabis and khat plant, respectively. In this review, we briefly discussed the chemistry, pharmacology and toxicology of five common NPS of natural origin, i.e., khat, kratom, salvia, magic mushroom and mandrake. Through the review, we hope that professionals and general public alike can pay more attention to the potential problems caused by natural NPS, and suitable control measures will be taken.

    2014-01-01

    The emergence of 'legal highs' or 'new psychoactive substances' (NPS) on the Irish market is reflective of their appearance in many countries, with some notable exceptions. The official response to the situation is examined here by looking at Irish controlled drugs legislation and drug enforcement policies as enacted in recent years and their effects on academic research on NPS. The philosophy and practice of outright bans of scheduled substances has not been effective in delivering the stated aims of illicit drug control, namely harm reduction. With these legislative changes, we have witnessed the removal of the 'legitimate' sale and open marketing of a number of NPS to the general public in commercial retail premises. However, as legislation was enacted, suppliers and vendors rapidly changed the contents of their legal high products from now controlled to non-controlled substances. We have found that it is administratively challenging to perform scientific research on controlled substances at academic institutions. It is desirable to gather analytical, pharmacological, and toxicological data on these substances as they emerge on the market but due to the restrictive nature of licensing requirements, once a substance or generic class of substances is controlled, this becomes more difficult. The facts that any quantity of substance, no matter how small, is controlled, the nomenclature used to describe compounds is not consistent within the enacted legislation and the use of catch-all classes of compounds with the intention of controlling many similar molecular structures, all create problematic issues for academic researchers.

    Full Text Available Context: The abuse of psychoactive substances which is one of the most important global public health problems begins in adolescence. Adolescents usually start by abusing the gateway substances. They suffer social, economic, physical, and legal consequences on account of use of substances, and this is very worrisome because of the increasing prevalence of use. Aims: The aim was to identify the characteristics of adolescents that use gateway substances. This knowledge shall be utilized in preventive programs. Settings and Design: Cross-sectional study with secondary school adolescents as participants. Subjects and Methods: Multistage sampling technique was used to select 492 respondents and the questionnaire consisted of characteristics of the adolescents, their families and schools and the alcohol, tobacco, cannabis, and stimulant use sections of the World Health Organisation questionnaire for student drug use surveys. Statistical Analysis Used: The data were analyzed using the Statistical Package for Social Sciences, and Chi-square statistics was used. Results: Having a friend who uses substance was significantly associated with tobacco, alcohol, cannabis, and caffeine use while being a male, having a family member that uses substance were significantly associated with tobacco, alcohol, and caffeine use. Older age, lack of satisfaction with the relationship with the teacher and polygamous family background were significantly associated with tobacco use. And finally, lack of satisfaction with the relationship with parents/guardians and having parents or guardians who are not religious were significantly associated with alcohol use. Conclusion: A comprehensive approach is needed to prevent the use of substances; this should target individuals, schools, families, and religious institutions.

    During the past few years, there has been an increasing recognition that Internet is playing a significant role in the synthesis, the distribution and the consumption of Novel Psychoactive Substances (NPS).The aim of this study was to assess the online availability of NPS in Persian language websites. The Google search engine was used to carry out an accurate qualitative assessment of information available on NPS in a sample of 104 websites. The monitoring has led to the identification of 14 NPS including herbal, synthetic, pharmaceutical and combination drugs that have been sold online. The availability of online marketing of NPS in Persian language websites may constitute a public health challenge at least across three Farsi-speaking countries in the Middle East. Hence, descriptions of this phenomenon are valuable to clinicians and health professional in this region. Further international collaborative efforts may be able to tackle the growth and expansion of regular offer of NPS.

    The use of psychoactive substances has been shown to be a risk factor for accidents in professional drivers. According to an approved Italian law, in order to detect dependency at the workplace the occupational health physician is called to assess the use of illicit drugs among professional drivers. The main purpose of this study was to investigate the use of psychoactive substances among professional drivers. From July to December 2008, rapid urine screening test was carried out on 198 professional drivers. All positive results from the screening stage were verified by specialized laboratories. We found 4 workers with a positive rapid urine screening test (7.1%), one of which was positive only for benzodiazepines and another positive test was not confirmed by specialized laboratory. By only considering illegal substances detected, 6.1% of the drivers tested positive. In this study, the high number of consumers among professional drivers ranged from 31 to 35 years old. Cannabis (THC) was the most frequently detected substance (seen in 10 over 12 cases,), after that was methadone (2/12 cases) and cocaine (1/12 case). We only had one case where more than one substance was found in the same subject (THC and cocaine). Five (41.7%) were former drug-addicts and public Pathological Addiction Services (Ser.T.) had previously followed them. Our results highlight the problem of drug consumption among professional drivers in Piedmont region. Health education and medical surveillance in workplace drug-testing may improve worker and third parties safety.

    For many teenagers the time of growing up is a period of trying prohibited substances. Nowadays apart from alcohol and tobacco new designed, psychoactive substances known as "smart drugs" or "legal highs" are available. Intensive development of their market is taking place in the last few years which is difficult to overcome by regulations only. Toxicological tests used now are not able to detect the presence of many such substances in the body. Designer drugs cause the interest of young people even from small towns and many times taking them give effects requiring medical help. Caffeine is also a psychoactive substance but depending on the dose it can have positive or detrimental effect. Recently there are more and more products with caffeine, especially drinks and dietary supplements, what can cause the increase of consumption of caffeine. Children are particularly exposed to the adverse effect of high consumption of caffeine because of their small body weight and development of the central nervous system. This article presents actual data about the market of designer drugs, frequency of using them, consumption of caffeine by children and teenagers and about the impact of these substances on the organism.

    In recent years the recreational use of new psychoactive substances (NPS) has increased. NPS are considered a threat to public health and the main response to this threat is to make the selling and buying of these substances illegal. In Sweden, during the last 5 years, 62 new substances have been classified as narcotics but little is known of the effects of making a particular substance illegal. The aim of this work is to study how legal status influences the interest in NPS in Sweden. Forty-five thousand posts made in a Swedish Internet discussion forum (Flashback Forum) related to eight NPS (MDPV, Methylone, 4-MEC, 4-HO-MET, MXE, 6-APB, AH-7921, and 3-MMC) were used to derive time-dependent measures of interest in these substances. Intervention analyses were used to investigate the effects of legal status on the forum interest. For all eight substances the activity on the forum (measured as number of posts per day) showed a drastic decrease around the time of classification. The statistical analysis showed that in seven of eight cases, the drop in activity could be accounted for by the legal status of the substances. The legal status of the substances was shown to have a substantial effect on the interest in the substances. The novel measure used to trace the interest in particular NPS could be a useful tool to follow trends in substance use in almost real-time. Copyright © 2015 Elsevier Ireland Ltd.

    In France, the law states that any person held in custody could be examined by a doctor. The main objective of the medical examination is to give medical evidence of health compatibility with custody. This review identifies health risks such as addictive behaviour. We wanted to know which psychoactive substances are used in this particular population, and how problematic these uses are. A prospective, monocentric, open-ended study conducted via a structured questionnaire was carried out on detainees who reported having taken drugs or illegal substances. Practitioners investigated desired effects for each substance, and characteristics of use, by means of the dependence criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (American Psychiatric Association, 1994). Problematic use was assessed when at least 3 items of the DSM IV were positive. 604 questionnaires were examined. 90.7% of questionnaires reported tobacco use, 76.2% cannabis, 57.3% alcohol, 12.5% psychostimulants, 10.0% opiates and 0.7% benzodiazepines or Z-drugs. The frequency of problematic use was 74.6% for opiates, 44.9% for cocaine and 25.3% for cannabis. Compared to non-problematic users, problematic users were older, more likely to be jobless without financial means, more likely to have a medical history, including a greater likelihood of mental illness, and more chance of undergoing prescribed medical treatment. They included more women and more homeless people. These results show characteristics of psychoactive substance use in a sample of people in custody. Psychoactive substances mentioned by respondents are not different from those observed in the general population, but for certain users, the desired effects are far from the pharmacologically expected ones. For some, taking substances seems to be part of their way of life, for others it is a means to compensate for an underlying feeling of uneasiness. Furthermore, problematic users present severity criteria which

    Before white man brought his alcohol to the South Pacific, the indigenes were using many wild plants possessing psychoactive properties. The most prominent were betel in much of Melanesia, kava in much of Polynesia, and pituri in much of Australia. The use of each of these three drugs was widespread, institutionalised as a ritual and the occasion for extensive trade. Each was valued for its effect in reducing tension or in producing altered states of consciousness. Each was also capable of inducing intoxication. Since few physicians nowadays have had my opportunity to observe the use of all three of these substances, their main features are recalled here. Attention is paid to their traditional use and probable future use, to their pharmacological and clinical properties, and to their place in the zeitgeist of people and period. There is no indication that these substances will be espoused by the drug enthusiasts of the West as avidly as other ethno-psychopharmacological agents such as Peruvian coca leaf, the Indian hemp, the Asian poppy, or the American tobacco. The possibility, however, of some use in the West cannot be discounted.

    In this paper the authors summarize experience of a drug service provider with the injecting use of novel psychoactive substances. Among clients of the needle exchange programme of Blue Point Drug Counselling and Outpatient Centre, the authors observed the spread of the novel substances since 2009. The extensive spread of the novel substances caused substantial change in injecting use patterns, thus in the usage of the needle exchange programme. The novel psychoactive substances appeared consecutively, so that this setting gave a unique opportunity to observe and track the emergence of these substances. The authors summarize the characteristics which are important for medical practice (risks, frequent use, severe psychopathological conditions) as well as special risks associated with these substances (substances with unknown composition and effect). They highlight the importance and role of the early warning system, monitoring the online sources of information and testing of samples containing novel psychoactive substances.

    New psychoactive substances (NPS) are synthesized compounds that are not usually covered by European and/or international laws. With a slight alteration in the chemical structure of existing illegal substances registered in the European Union (EU), these NPS circumvent existing controls and are thus referred to as "legal highs". They are becoming increasingly available and can easily be purchased through both the internet and other means (smart shops). Thus, it is essential that the identification of NPS keeps up with this rapidly evolving market. In this case study, the Belgian Customs authorities apprehended a parcel, originating from China, containing two samples, declared as being "white pigments". For routine identification, the Belgian Customs Laboratory first analysed both samples by gas-chromatography mass-spectrometry and Fourier-Transform Infrared spectroscopy. The information obtained by these techniques is essential and can give an indication of the chemical structure of an unknown substance but not the complete identification of its structure. To bridge this gap, scientific and technical support is ensured by the Joint Research Centre (JRC) to the European Commission Directorate General for Taxation and Customs Unions (DG TAXUD) and the Customs Laboratory European Network (CLEN) through an Administrative Arrangement for fast recognition of NPS and identification of unknown chemicals. The samples were sent to the JRC for a complete characterization using advanced techniques and chemoinformatic tools. The aim of this study was also to encourage the development of a science-based policy driven approach on NPS. These samples were fully characterized and identified as 5F-AMB and PX-3 using (1)H and (13)C nuclear magnetic resonance (NMR), high-resolution tandem mass-spectrometry (HR-MS/MS) and Raman spectroscopy. A chemoinformatic platform was used to manage, unify analytical data from multiple techniques and instruments, and combine it with chemical and

    The use of psychoactive substances among the prison population is an important public health issue because of its magnitude and health consequences. The aim of this study was to estimate the prevalence of psychoactive substance use among the prison population and to analyse its association with sociodemographic and penitentiary factors, particularly the size of the prison. Data were gathered using a self-administered questionnaire among 2,484 random male inmates in eight prisons of different sizes in Spain. The prevalence of psychoactive substance use with 95% confidence intervals (95% CI) during the last 6 months in prison were estimated. Prevalence ratios were used to estimate the association between psychoactive substance use and sociodemographic and penitentiary characteristics. The prevalence of psychoactive substance use in the past 6 months in prison was 59.9% (95% CI: 57.9-62.0). Notable among the sociodemographic variables associated with substance use were drug consumption prior to imprisonment (6.90; 95% CI: 5.51-8.65) and recidivism in prison (2.41; 95% CI: 2.04-2.85). The largest prisons showed a higher frequency of drug use than other prisons. A high prevalence of psychoactive substance use was found in prisons and significant differences were found according to delinquent profile and the size of the prison. Copyright © 2015 SESPAS.

    The abuse of new psychoactive substances (NPS) and methamphetamine has severe adverse effects. Here we provide the first report of regional patterns in NPS and methamphetamine consumption in Germany, on the basis of epidemiologic data from six federal states (Bavaria, Hamburg, Hesse, North Rhine-Westphalia, Saxony, and Thuringia). Data were derived from the 2015 Epidemiological Survey of Substance Abuse (Epidemiologischer Suchtsurvey) and supplemented with additional cases from the federal states that were studied. The numbers of persons included in the representative samples of persons aged 18 to 64 in each state were 1916 (Bavaria), 1125 (Hamburg), 1151 (Hesse), 2008 (North Rhine-Westphalia), 1897 (Saxony), and 1543 (Thuringia). Potential risk factors for the lifetime prevalence of consumption were studied by logistic regression. The lifetime prevalence of methamphetamine consumption in the individual states ranged from 0.3% (North Rhine-Westphalia) to 2.0% (Saxony). Thuringia and Saxony displayed values that were significantly higher than average. For NPS, the figures ranged from 2.2% (Bavaria) to 3.9% (Hamburg), but multivariate analysis revealed no statistically significant differences between the states. Higher age and higher educational level were associated with lower consumption of NPS and methamphetamine, while smoking and cannabis use were each associated with higher consumption. NPS consumption is equally widespread in all of the federal states studied. Methamphetamine is rarely consumed; its consumption appears to be higher in Saxony and Thuringia. The risk factor analysis reported here should be interpreted cautiously in view of the low case numbers with respect to consumption.

    Epidemiological monitoring of drug use among adolescents or young adults is a major concern for public policy makers. This surveillance requires the use of adapted methodological solutions. This article presents how far epidemiological surveillance is a useful tool for monitoring drug use at adolescence. It also presents the results of the French general population surveys among adolescents or young adults, and the trends in the last decade. It relies on a survey among 17 years old adolescents and a general population survey among adults (analysis is restricted to people aged 18-25). A European school survey among 16 years old is also presented to compare the French situation to other European countries levels of use. The use of psychoactive substance increases fast with age during adolescence however results vary from one substance to another. Since year 2000, tobacco use is decreasing when alcohol use frequency appears stable between 2003 and 2005, although drunkenness has increased from 2000 to 2005. The frequency of lifetime or occasional use of cannabis appears stable since 2000. Among 17 years old, the proportion of regular users of cannabis has been stable between 2000 and 2005. Finally, the prevalence of ecstasy and cocaine increased during this period of time, despite being less than 4%, but the levels of the other illicit substances are low and stable. The results on alcohol variables and tobacco use in France are rather close to the European average. Four out of five 16 years old students had drunk alcohol during the past 12 months and 36 percent had been drunk during this period (vs 39% in the average European country). About one-third of the students had smoked cigarettes during the past 30 days (close to the 29% in the average European country). The use of cannabis, however, is clearly more prevalent in France. Almost one-third (31%) of the students had already used cannabis (vs 19% in the average European country). The use of inhalants was reported

    Alcohol and psychoactive substance use and their effects are an important issue among adolescents and young adults. Different results have been reported about the frequency of alcohol and psychoactive substance use among university students in studies conducted both in Turkey and in different places worldwide. The frequency of alcohol and psychoactive substance use among Trakya University students (n=1385) and the related parameters were studied cross-sectionally using a self-reporting questionnaire. Alcohol was the most common substance used (30%), followed by tobacco (29.9%) and marijuana (3.1%). The frequency of alcohol and psychoactive substance use was found to be higher among males with higher amounts of pocket money, whose parents experienced more conflict in their relationship, and who belong to families with a higher education and income level. The frequency of alcohol and psychoactive substance use among Trakya University students was found to be lower than other regions in Turkey and particularly lower than the levels reported in studies conducted in other countries.

Socio-economic changes that occurred in the wake of dismemberment of former Yugoslavia resulted in the appearance of social pathology, one of which was the increase in the use of psychoactive substances. The over whole epidemiological research in the use of psychoactive substances has not been conducted so far. The aim of this study was to establish the type and form of the use of psychoactive substances considering sex and age, as well as risk factors for the use of psychoactive substances among the children and adolescents. Methods. The research was carried out among 1011 elementary school children (seventh and eighth grades and secondary school children (all four grades in the area of Belgrade from October 2003 to January 2004. Out of the total number 457 (45.2% were elementary school pupils and 554 (54.8% secondary school pupils. There were 524 (51.8% boys and 487 (48.2% girls, aged from 12 to 18 years (the average age being 15.3 years.

    Psychoactive substance use has become a major public health problem among students in Ethiopian universities. Hence, this study aimed to investigate the magnitude and determinants of psychoactive substances use (khat chewing, alcohol drinking and cigarette smoking) among undergraduate students of Woldia University, Ethiopia. Institution based quantitative cross-sectional study was employed on Woldia University students in April 2015. 730 students were included in the study. Data were collected using self-administered questionnaires. EpiData version 3.02 was used to enter data. Then, data were exported to SPSS version 20 for analysis. The lifetime prevalence of alcohol drinking, khat chewing and cigarette smoking among the study students were 33.1, 13 and 7.9%, respectively. Likewise, the current prevalence of alcohol drinking, khat chewing and cigarette smoking was 27.9, 10.4 and 6.4%, respectively. More than half of the surveyed students (59.1%) were introduced to psychoactive substance use by peer pressure. About 66% of the study participants believed that psychoactive substances are important for relaxation, and 19% to relief from stress. Students who were Muslims [adjusted odds ratio (AOR) 3.74, 95% CI (1.57, 8.91)], Oromo ethnic group [AOR 2.63, 95% CI (1.19, 5.81)], ever drunk alcohol [AOR 6.32, 95% CI (2.96, 13.48)] and ever smoked cigarette [AOR: 9.16, 95% CI (4.33, 19.38)] were positively associated with khat chewing. Furthermore, pocket money and ever khat chewing were associated with alcohol drinking and cigarette smoking. This study showed that psychoactive substances use is somewhat prevalent among students in Woldia University. Hence, support of religious institutions in providing education aimed at preventing substance use, establishing and strengthening peer educators in the university are important interventions to tackle psychoactive substances use.

    Research exploring the relationship between addictions and experiences of bullying suggests that problem behaviors may generally be associated with an increased risk of victimization. The aim of the present study was to examine the role of psychoactive substance use, excessive Internet use, and social support in both traditional offline bullying and online "cyberbullying" victimization in a nationally representative sample of adolescents ( N  = 6237; 51% male; M age  = 16.62 years, SD = 0.95). Results demonstrated that traditional bullying victimization was associated with cyberbullying victimization. Furthermore, psychoactive substance use and problematic Internet use predicted both traditional bullying and cyberbullying victimization. Finally, perceived social support was found to be an important protective factor against both traditional and cyberbullying victimization. However, psychoactive substance use and problematic Internet use accounted for only a small proportion of variance in victimization.

    In the recent years, new molecules have appeared in the illicit market, claimed to contain "non-illegal" compounds, although exhibiting important psychoactive effects; this heterogeneous and rapidly evolving class of compounds are commonly known as "New Psychoactive Substances" or, less properly, "Smart Drugs" and are easily distributed through the e-commerce or in the so-called "Smart Shops". They include, among other, synthetic cannabinoids, cathinones and tryptamine analogs of psylocin. Whereas cases of intoxication and death have been reported, the phenomenon appears to be largely underestimated and is a matter of concern for Public Health. One of the major points of concern depends on the substantial ineffectiveness of the current methods of toxicological screening of biological samples to identify the new compounds entering the market. These limitations emphasize an urgent need to increase the screening capabilities of the toxicology laboratories, and to develop rapid, versatile yet specific assays able to identify new molecules. The most recent advances in mass spectrometry technology, introducing instruments capable of detecting hundreds of compounds at nanomolar concentrations, are expected to give a fundamental contribution to broaden the diagnostic spectrum of the toxicological screening to include not only all these continuously changing molecules but also their metabolites. In the present paper a critical overview of the opportunities, strengths and limitations of some of the newest analytical approaches is provided, with a particular attention to liquid phase separation techniques coupled to high accuracy, high resolution mass spectrometry.

Most of the patients suffering from panic disorder fulfilled the criteria for the diagnosis of anxiety disorder induced by use of the substance: 11 (22.9 % of them had panic attacks only while under the effect of drugs or during the withdrawal syndrome, i.e., secondarily to the use of drugs. Sixteen (33.3 % of the patients had social phobia, and in all of them, the social phobia began before the use of psychoactive substances. CONCLUSIONS: The findings confirmed the high frequency of social phobia in psychoactive substance-dependent patients and they reinforce the self-medication hypothesis in this comorbidity, since that kind of phobia tends to precede the use of drugs. As for panic disorder, in our sample it appears to derive from a complication of the use of psychoactive substances.

    New psychoactive substances (NPS), are now a large group of substances of abuse not yet completely controlled by international drug conventions, which may pose a public health threat. Anxiety, paranoia, hallucinations, seizures, hyperthermia and cardiotoxicity are some of the common adverse effects associated with these compounds. In this paper, three case reports taken from the archive of processed cases of the authors' laboratory are presented and discussed to stress the risks of possible adverse consequences for NPS users: in particular, (i) the risk deriving from the difficulty of predicting the actual consumed dose, due to variability of active ingredients concentration in consumed products, (ii) the risk deriving from the difficulty of predicting the actual active ingredients present in consumed products, as opposed to those claimed by the manufacturer, and (iii) the risk deriving from the difficulty of predicting the actual pharmacological and toxicological effects related to the simultaneous consumption of different psychoactive ingredients contained in single products, whose interactions are mostly unknown. Each of them individually provide a source of concern for possible serious health related consequences. However, they should be considered in conjunction with each others, with the worldwide availability of NPS through the web and also with the incessantly growing business derived from the manipulation and synthesis of new substances. The resulting scenario is that of a cultural challenge which demands a global approach from different fields of knowledge. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Objective. Comorbidities between psychiatric diseases and consumption of traditional substances of abuse (alcohol, cannabis, opioids, and cocaine are common. Nevertheless, there is no data regarding the use of novel psychoactive substances (NPS in the psychiatric population. The purpose of this multicentre survey is to investigate the consumption of a wide variety of psychoactive substances in a young psychiatric sample and in a paired sample of healthy subjects. Methods. A questionnaire has been administered, in different Italian cities, to 206 psychiatric patients aged 18 to 26 years and to a sample of 2615 healthy subjects matched for sex, gender, and living status. Results. Alcohol consumption was more frequent in the healthy young population compared to age-matched subjects suffering from mental illness (79.5% versus 70.7%; P<0.003. Conversely, cocaine and NPS use was significantly more common in the psychiatric population (cocaine 8.7% versus 4.6%; P=0.002 (NPS 9.8% versus 3%; P<0.001. Conclusions. The use of novel psychoactive substances in a young psychiatric population appears to be a frequent phenomenon, probably still underestimated. Therefore, careful and constant monitoring and accurate evaluations of possible clinical effects related to their use are necessary.

    New Zealand's Psychoactive Substances Act (2013) established the world's first regulated market for 'low risk' psychoactive products ('legal highs'). Under an interim PSA regime, 47 existing products were permitted to be continued to be sold. To explore issues with the implementation of regulatory systems to monitor the safety of products on the legal market under the interim Psychoactive Substances Act regime. Semi-structured interviews with 30 key stakeholders, including industry, government agency, health and drug service professionals were conducted, transcribed and analysed thematically. In retrospect stakeholders questioned the decision to approve strong synthetic cannabinoid smoking products, noting their health risks because of product formulation, inconsistent manufacturing practices and smoking as the means of administration. Industry actors claimed the decision to approve synthetic cannabinoid smokeable products prevented potentially safer products from gaining market share. The system for withdrawing approved products which were subsequently found to be harmful was criticised for the poor quality of data available, limited engagement with health professionals and the slowness of product withdrawal. Many of the problems with the regime were attributed to the urgency under which the legal market under the interim Psychoactive Substances Act was established and implemented. The selection of 'safer' products, implementation of the product monitoring system, and engagement with health professionals may have benefited from more time and resources. An incremental approach to establishing the new market may have made the regulatory management of the new regime more workable. [Rychert M, Wilkins C, Witten K.

    This study aims to identify the frequency of risk and protection factors related to drug consumption among undergraduate nursing students. It is a cross-sectional study in which authors applied the instrument Risk and Protection Factors for the Consumption of Psychoactive Substances, validated for use with undergraduate nursing students. Data were analyzed through STATA 10. Three hundred and ninety students participated in the study. The domain "prejudice and appraisal", "social permissiveness and access to psychoactive substances", "social skills and self-control" are risk factors for drugs use in 100% of participants. "Spirituality" and "satisfaction with interpersonal relations" were predominant protective domains. Based on data, authors can conclude that the students did not consider the risks in alcohol and tobacco consumption, as they think it is normal and socially acceptable.

    Background  Recently, scientific interest in the therapeutic potential of serotonergic and psilocybin hallucinogens (psychedelics) such as lysergic acid diethylamide (LSD) and entactogens like 3,4-methylendioxymethamphetamine (MDMA) within the framework of psychotherapy has resumed. The present article provides an overview on the current evidence on substance-assisted psychotherapy with these substances. Method  A selective search was carried out in the PubMed and Cochrane Library including studies investigating the clinical use of serotonergic psychoactive substances since 2000. Results  Studies were found investigating the following indications: alcohol (LSD and psilocybin) and tobacco addiction (psilocybin), anxiety and depression in patients suffering from life-threatening somatic illness (LSD and psilocybin), obsessive-compulsive disorder (OCD) (psilocybin), treatment-resistant major depression (psilocybin), and posttraumatic stress disorder (PTSD) (MDMA). Discussion  Substance use disorders, PTSD and anxiety and depression in patients suffering from life-threatening somatic illness belong to the indications with the best evidence for substance-assisted psychotherapy with serotonergic psychoactive agents. To date, studies indicate efficacy and relatively good tolerability. Further studies are needed to determine whether these substances may represent suitable and effective treatment options for some treatment-resistant psychiatric disorders in the future. © Georg Thieme Verlag KG Stuttgart · New York.

  7. Deep brain stimulation in addiction due to psychoactive substance use.

    2013-01-01

    Addiction is one of the most challenging health problems. It is associated with enormous individual distress and tremendous socioeconomic consequences. Unfortunately, its underlying mechanisms are not fully understood, and pharmacological, psychological, or social interventions often fail to achieve long-lasting remission. Next to genetic, social, and contextual factors, a substance-induced dysfunction of the brain's reward system is considered a decisive factor for the establishment and maintenance of addiction. Due to its successful application and approval for several neurological disorders, deep brain stimulation (DBS) is known as a powerful tool for modulating dysregulated networks and has also been considered for substance addiction. Initial promising case reports of DBS in alcohol and heroin addiction in humans have recently been published. Likewise, results from animal studies mimicking different kinds of substance addiction point in a similar direction. The objective of this review is to provide an overview of the published results on DBS in addiction, and to discuss whether these preliminary results justify further research, given the novelty of this treatment approach. © 2013 Elsevier B.V.

    A survey was conducted during 2015 to monitor psychoactive substance use in a sample of drivers in Spanish roads and cities. Traffic police officers recruited drivers at sites carefully chosen to achieve representativeness of the driver population. A brief questionnaire included the date, time, and personal and driving patterns data. Alcohol use was ascertained through ethanol breath test at the roadside and considered positive if concentrations >0.05mg alcohol/L were detected. Four drug classes were assessed on-site through an oral fluid screening test that, if positive, was confirmed through a second oral fluid sample at a reference laboratory. Laboratory confirmation analyses screened for 26 psychoactive substances. To evaluate the association between drug findings and age, sex, road type (urban/interurban), and period of the week (weekdays, weeknights, weekend days, weekend nights), logistic regression analyses were done (overall, and separately for alcohol, cannabis and cocaine). A total of 2744 drivers, mean age of 37.5 years, 77.8% men, were included. Overall, 11.6% of the drivers had at least one positive finding to the substances assessed. Substances more frequently testing positive were cannabis (7.5%), cocaine (4.7%) and alcohol (2.6%). More than one substance was detected in 4% of the subjects. The proportion of positive results decreased with age, and was more likely among men and on urban roads. The pattern for alcohol use was similar but did not change with age and increased among drivers recruited at night. Cannabis was more likely to be detected at younger ages and cocaine was associated with night driving. Alcohol use before driving has decreased over the last decade; however, the consumption of other illegal drugs seems to have increased. The pattern of illegal psychoactive substance observed is similar to that declared in surveys of the general population of adults. Copyright © 2017. Published by Elsevier B.V.

    The web-based open sale of unregulated new psychoactive substances (NPS) has shown a steady increase in recent years. Analysis of drug products sold as NPS is useful to confirm the true chemical contents, for comparison with the substances detected in corresponding body fluids, but also to study drug trends. This work describes the examination of 251 drug products that were randomly submitted for analysis in 173 cases of suspected NPS-related intoxications in the Swedish STRIDA project in 2010-2015. Of the products, 39% were powders/crystals, 32% tablets/capsules, 16% herbal materials, 8% liquids, 1% blotters, and 4% others. The analysis involved tandem mass spectrometry and nuclear magnetic resonance spectroscopy. In 88 products (35%), classic psychoactive substances, prescription pharmaceuticals, dietary supplements, or doping agents were found; however, in none of these cases had an NPS-related intoxication been indicated from product markings or patient self-reports. Another 12 products tested negative for psychoactive substances. The remaining 151 products contained 86 different NPS (30% contained ≥2 substances). In 104 drug products, a specific NPS ingredient was indicated based on labelling (69%) or patient self-report; in 92 cases this was also analytically confirmed to be correct. Overall, the NPS products submitted for analysis in the STRIDA project showed a high degree of consistency between suspected and actual content (88%). The results of related urine and/or blood analysis further demonstrated that the patients commonly (89%) tested positive for the indicated NPS, but also revealed that polysubstance intoxication was common (83%), indicating use of additional drug products.

    New psychoactive substances (NPS) continue to emerge; however, few surveys of substance use ask about NPS use. Research is needed to determine how to most effectively query use of NPS and other uncommon drugs. To determine whether prevalence of self-reported lifetime and past-year use differs depending on whether or not queries about NPS use are preceded by "gate questions." Gate questions utilize skip-logic, such that only a "yes" response to the use of specific drug class is followed by more extensive queries of drug use in that drug class. We surveyed 1,048 nightclub and dance festival attendees (42.6% female) entering randomly selected venues in New York City in 2016. Participants were randomized to gate vs. no gate question before each drug category. Analyses focus on eight categories classifying 145 compounds: NBOMe, 2C, DOx, "bath salts" (synthetic cathinones), other stimulants, tryptamines, dissociatives, and non-phenethylamine psychedelics. Participants, however, were asked about specific "bath salts" regardless of their response to the gate question to test reliability. We examined whether prevalence of use of each category differed by gate condition and whether gate effects were moderated by participant demographics. Prevalence of use of DOx, other stimulants, and non-phenethylamine psychedelics was higher without a gate question. Gate effects for other stimulants and non-phenethylamine psychedelics were larger among white participants and those attending parties less frequently. Almost one in ten (9.3%) participants reporting no "bath salt" use via the gate question later reported use of a "bath salt" such as mephedrone, methedrone, or methylone. Omitting gate questions may improve accuracy of data collected via self-report.

    The quantification of illicit drug and pharmaceutical residues in sewage has been shown to be a valuable tool that complements existing approaches in monitoring the patterns and trends of drug use. The present work delineates the development of a novel analytical tool and dynamic workflow for the analysis of a wide range of substances in sewage-based samples. The validated method can simultaneously quantify 51 target psychoactive substances and pharmaceuticals in sewage-based samples using an off-line automated solid phase extraction (SPE-DEX) method, using Oasis HLB disks, followed by ultra-high performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UHPLC-QTOF) in MS(e). Quantification and matrix effect corrections were overcome with the use of 25 isotopic labeled internal standards (ILIS). Recoveries were generally greater than 60% and the limits of quantification were in the low nanogram-per-liter range (0.4-187 ng L(-1)). The emergence of new psychoactive substances (NPS) on the drug scene poses a specific analytical challenge since their market is highly dynamic with new compounds continuously entering the market. Suspect screening using high-resolution mass spectrometry (HRMS) simultaneously allowed the unequivocal identification of NPS based on a mass accuracy criteria of 5 ppm (of the molecular ion and at least two fragments) and retention time (2.5% tolerance) using the UNIFI screening platform. Applying MS(e) data against a suspect screening database of over 1000 drugs and metabolites, this method becomes a broad and reliable tool to detect and confirm NPS occurrence. This was demonstrated through the HRMS analysis of three different sewage-based sample types; influent wastewater, passive sampler extracts and pooled urine samples resulting in the concurrent quantification of known psychoactive substances and the identification of NPS and pharmaceuticals.

    Studies investigating risk-related behavior in relation to new psychoactive substance (NPS) use are sparse. The current study investigated characteristics of NPS users by comparing risk-related behavior of NPS users to that of illicit drugs (ID) users and licit substances users and non-users (NLC) users. In this cross-sectional study we included 528 individuals across an age range of 18-72years. Using a web-based questionnaire we collected self-report data on substance use, sensation seeking, impulsivity, peer substance use and risk perception of substance use. NPS and ID users had a higher level of sensation seeking compared to NLC users (NPS users: pusers: pusers (pusers (p=0.16), had increased levels of impulsivity compared to NLC users. NPS users had significantly higher scores for sensation seeking (F 1,423 =51.52, pusers. Additionally, NPS users had significantly more peers who use substances compared to ID and NLC users. Also, NPS and ID users had lower risk perception for most substances than NLC users. NPS users had lower risk perception for most substances than ID users. The findings highlight that NPS users show substantial more risk-related behavior than both ID and NLC users. Therefore, NPS users might be considered as a distinctive group of substance users that need another approach in terms of prevention. Copyright © 2017 Elsevier Ltd. All rights reserved.

    People who consume psychoactive substances may experience situations of social stigma on the part of the society in general, and also situations of internalized-stigma derived from their own consumption of substances. The Internalized Stigma of Mental Illness (ISMI) scale has been shown to be valid and reliable to evaluate the internalized-stigma in people with severe mental disorders, but in Argentina there is no a Spanish version of this scale for use with people who use psychoactive substances. The objective of this work was to evaluate the psychometric properties of the Spanish version of the Internalized Stigma of Mental Illness instrument adapted for people who use psychoactive substances. The work was carried out on a sample of 200 patients older than 18 years under treatment of rehabilitation by consumption of psychoactive substances in a public institution of the city of Córdoba (Argentina) between the years 2014 and 2016. The instrument used was the Internalized Stigma of Mental Illness (ISMI) previously adapted for use in these groups of patients. It was determined the reliability of the scale through Cronbach's coefficients α and factorial structure was analyzed through an exploratory factor analysis. The obtained coefficients showed a high reliability, while in the factorial structure emerged the 4 theoretical dimensions described by Ritsher, namely: social isolation, perceived discrimination, alienation and stereotyping. It is concluded that the scale adapted for people who use psychoactive substances is reliable and with an adequate factorial structure.

    Although scarce, the data about acute poisonings with psycho-active substances during the period of socioeconomic crisis in Bulgaria indicate the appearance and increase of the use of inhalants, prescribed and over-the-counter medications and the increase of acute poisoning rate with heroin. To ascertain some characteristics of acute poisonings with psycho-active substances in Plovdiv region from 01.01.1990 to 31.12.2000. The whole caseload of 571 acute poisonings with psycho-active substances in Plovdiv region (8.8% of the population of the country) between 1990 and 2000, treated in the only Clinic of Toxicology in the region is studied retrospectively. The variables gender, age, type of psycho-active substance (DSM-IV criteria), grade of severity, duration of use, times of poisoning and some differences between alcohol and opioid poisonings are investigated. Acute poisoning with psycho-active substances are 5.43% of all intoxications. The moderate grade of severity (48.5%), alcohol (62.8%) and opioid (15.3%) intoxications, debut poisoning (86.8%) and poisonings occurring in the initial period of use predominate. An increase of acute poisonings with psycho-active substances in the last third of the studied period (1990-2000) is established--severe forms (2.59 times) and recidivistic intoxication (4 times). Alcohol and opioid poisonings predominate among severe intoxications. The hospital stay is relatively short--1.75 +/- 0.67 and hospital lethality is 1.6%. 1. The moderate grade of severity, alcohol and opioid intoxications (especially in the severe grade cases), occurrence in the initial period of use and relatively short hospital stay predominate in acute poisonings with psycho-active substances in the period of socioeconomic crisis. Hospital lethality (1.6%) is ascertained only in severe alcohol intoxication. 2. An increase of acute poisonings with psycho-active substances--severe forms, mild forms and recidivistic intoxications is established in the last

    Consumption of psychoactive substances among the youth is suggestive of a trend indicating an accelerated and continual growth of the tendency in question. This research was aimed at investigating the frequency of psychoactive substance consumption among high school students on the territory of the town of Kragujevac so that the adequate measures on prevention could be taken. Data from the questionnaire answered by high school student attending the 1st and 4th grade of the medical, technical and economic high schools in Kragujevac were thereby used. The survey included the overall number of 1280 students: there were 793 (62%) male participants and 487 (38%) female. The research was conducted from October 2007 until January 2008. The questionnaire from the project "Health Status, Health Needs and Utilization of Health Care of the Population of Serbia" conducted by the Institute of Public Health of Serbia "Dr Milan Jovanović Batut" in 2000 was used in the survey. According to the answers, alcohol was used by 45.5%, cigarettes by 20% and drugs by 3.1% of the examined subjects. Following the use of alcohol and cigarettes, the most often used psychoactive substance was cannabis, which was consumed by 7.8% of the examined subjects out of who 9.8% were boys and 4.8% were girls. Since the risky behaviour seems not to be isolated and individual but rather as a combination of several forms of it, school programmes should treat young people before certain forms of behaviour are established. Family, school, health service and society should work on an organized basis as well as methodically on prevention and on fighting against these inadequate habits.

  17. Next generation of novel psychoactive substances on the horizon - A complex problem to face.

    Zawilska, Jolanta B; Andrzejczak, Dariusz

    2015-12-01

    The last decade has seen a rapid and continuous growth in the availability and use of novel psychoactive substances (NPS) across the world. Although various products are labeled with warnings "not for human consumption", they are intended to mimic psychoactive effects of illicit drugs of abuse. Once some compounds become regulated, new analogues appear in order to satisfy consumers' demands and at the same time to avoid criminalization. This review presents updated information on the second generation of NPS, introduced as replacements of the already banned substances from this class, focusing on their pharmacological properties and metabolism, routes of administration, and effects in humans. Literature search, covering years 2013-2015, was performed using the following keywords alone or in combination: "novel psychoactive substances", "cathinones", "synthetic cannabinoids", "benzofurans", "phenethylamines", "2C-drugs", "NBOMe", "methoxetamine", "opioids", "toxicity", and "metabolism". More than 400 NPS have been reported in Europe, with 255 detected in 2012-2014. The most popular are synthetic cannabimimetics and psychostimulant cathinones; use of psychedelics and opioids is less common. Accumulating experimental and clinical data indicate that potential harms associated with the use of second generation NPS could be even more serious than those described for the already banned drugs. NPS are constantly emerging on the illicit drug market and represent an important health problem. A significant amount of research is needed in order to fully quantify both the short and long term effects of the second generation NPS, and their interaction with other drugs of abuse.

  20. Current challenges and problems in the field of new psychoactive substances in Germany from a law enforcement perspective.

    Duffert, Anna

    2014-01-01

    Over the last few years, a range of so-called new psychoactive substances (NPS) have established themselves on the German recreational drug scene, causing increased concern. At the same time, a great number of Internet shops have come into existence offering these substances for sale online, ensuring a high level of availability. A number of these substances derived from pharmaceutical research which did not result in marketing authorization, presumably due to unfavourable properties. There are hardly any reliable data on long-term health damage, addictive potential, and other aspects of these scientifically unexplored substances. A number of fatal intoxications have also become known. As a rule, the mostly young consumers do not know what substance they are taking and in what concentration, thus exposing themselves to incalculable health risks and consequences. The punishability of the handling of NPS depends on the actual content: the Narcotic Drugs Act (BtMG) is applicable if a product contains narcotic drugs. If similarly effective substances are contained, which are not classified as narcotic drugs, the (penal) provisions of the Medicinal Products Act might be applicable, if the product has a pharmaceutical effect. Experience gained so far has shown that manufacturers of these intoxicating substances react immediately to inclusions in the German BtMG and put new substances on the market which are chemically similar to the known substances thus circumventing legislation. In view of the immense variety of NPS and the enormous profits derived from their sale, an end to this development is not in sight. Copyright © 2014 John Wiley & Sons, Ltd.

    To assess the alcohol consumption, tobacco addiction and psychoactive substance use (PSU) of people living with HIV (PLHIV). Cross-sectional study in an HIV outpatient unit. Autoquestionnaire systematically proposed to all patients during their usual clinical care visit during a 6-months period, for alcohol (AUDIT test), tobacco (Short Fagerstrom Test) and PSU (ASSIST V3.0 test). Of 1334 distributed questionnaires, 1018 PLHIV responded: 76.8% were men [528 patients were MSM), and the median age was 49 years (interquartile range: 42-46). A prevalence of excessive alcohol drinking was found in 22% [95% confidence interval (CI) 19.5-24.7%] and 44.6% (CI 41.5-47.7%) were current smokers, with high dependence in 29.1% (CI 24.9-33.7%). The prevalence of PSU was 37.8% (CI 34.8-41%) in the past 3 months: cannabis 27.7%, poppers 16.4%, cocaine 8.9%, psychotropic medications 7.1%, gamma-hydroxybutyrate/gamma-butyrolactone (GHB/GBL) 4.7%, stimulants 3.1%, synthetic cathinones 2.7%, hallucinogens 1.5%. In the past 3 months, PSU was more prevalent in MSM than in non-MSM patients (46 versus 30%, P poppers) 31.0 versus 1.1%, GHB/GBL 7.8 versus 0.8%, stimulants 5.0 versus 1.1%, synthetic cathinones 4.9 versus 0.3%, and hallucinogens 2.3 versus 0.5%. Given the high prevalence of PSU and other addictions (alcohol and smoking) among PLHIV, and particularly among MSM, a systematic screening of PSU and other addictions should be part of routine clinical care.

    To undertake a critical review of literature on use of legal and illegal psychoactive substances (PAS) in persons with spinal cord injury (SCI) before and after trauma. Hundred and five articles published between 1980 and 2014 on alcohol and drug use in persons with SCI before and after trauma were retrieved from the PubMed and PsycInfo search engines. Before injury, 25% to 96% of people with SCI reported using alcohol, while 32% to 35% had used illegal drugs. At the time of injury, 31% to 50% of individuals with SCI were intoxicated with alcohol, 16% to 33% with drugs and 26% with a combination of drugs and alcohol. Among those reporting PAS use before injury, up to 50% stated that they had reduced their use during active rehabilitation, during which time only 6% consumed psychoactive substances for the first time. A variety of risk factors are associated with consumption subsequent to spinal cord injury: personality alteration (impulsiveness, aggressiveness), posttraumatic depression, poor coping skills, lack of social support and pain. PAS use can affect the process of rehabilitation, diminish the effectiveness of medication and result in various medical complications. Few studies have explored the use of alcohol, drugs and psychoactive medications before SCI and during active rehabilitation. To our knowledge, no study has analyzed the evolution of PAS use after hospital discharge, even though return home is associated with new stressors that may trigger risky behaviors. It should be a priority, as early as possible during rehabilitation, to detect persons at risk of developing PAS abuse. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Background Drugs of abuse (DOA) are widely used in the United States and are ubiquitous at outdoor music festivals. Attendees at music festivals are at high-risk for novel psychoactive substance (NPS) use, which is becoming more prevalent worldwide. No U.S. studies have employed an qualitative approach to investigate the etiologies of both traditional DOA and NPS use amongst music festival attendees. Objectives The objective of this study was to improve understanding of the knowledge, attitudes, beliefs, and practices of festival attendees using NPS and DOA. Methods We conducted semi-structured interviews of 171 attendees during the Sonic Bloom and Arise music festivals in Colorado in 2015 and 2016. Discrete variables were summarized with descriptive statistics. The anonymous, multi-domain interview documented the knowledge, attitudes beliefs, and practices underlying DOA use, which were analyzed with qualitative methods. Results We enrolled 171 participants that endorsed DOA use at the festivals. Most were experienced DOA users, who perceived minimal risks associated with DOA and NPS use. Nearly all unanimously reported normalization of DOA at music festivals. Participants popularly cited empathogenic, entactogenic, and entheogenic effects of DOA as their primary motivations for use. NPS use was endorsed by 39.8% (n = 68) of respondents, all of whom identified as being experienced DOA users. Conclusions This population of novel psychoactive substance users is primarily composed of experienced drug users that endorsed use because of low cost, minimal perceived risk, accessibility, and normalization of drug use at music festivals.

    To analyze the relationship between utilization patterns for condoms and other contraceptive methods and the consumption of alcohol and drugs. Exploratory study based on data from a probabilistic sample of 5,040 interviewees aged 16 to 65 years living in large urban regions of Brazil in 2005. The data were collected by means of questionnaires. The chi-square automatic interaction classification tree technique was used to study the use of condoms among interviewees of both sexes and other contraceptive methods among women, at the time of the last vaginal sexual intercourse. Among young and middle-aged adults of both sexes and young men in stable relationships, condom use was less frequent among those who said they used psychoactive substances (alcohol and/or illegal drugs). The possible modulating effect of psychoactive substances on contraceptive practices among mature women seems to be more straightforward, compared to the more subtle effects observed among younger women, for whom the different social classes they belonged to seemed to play a more important role. Despite the limitations resulting from an exploratory study, the fact that this was a representative sample of the urban population of Brazil and not from vulnerable populations, reinforces the need to implement integrated public policies directed towards the general population, with regard to preventing drug consumption, alcohol abuse, sexually transmitted infections, HIV/AIDS and unwanted pregnancy and promoting sexual and reproductive health.

    Introduction. Taking psychoactive substances constitutes a significant problem for Public Health, particularly in preventing drug abuse and addiction. Objectives. To estimate the amount and incidence of drug consumption in middle and high school pupils, including the circumstances in which drug taking first started, and to determine pupils' knowledge about the consequences of taking psychoactive substances and designer drugs (DDs). Materials and methods. A randomised study was conducted throughout Poland on 9,360 pupils attending middle school (junior high school) in 2009 and 7,971 pupils from middle and high school pupils in 2011. The survey consisted of a questionnaire devised by the Chief Sanitary Inspectorate (GIS) and the replies obtained were subject to the relevant statistical analyses. Results. Drug taking was found to have increased between 2009-2011, especially among those attending high school; proportionally rising from 4% - 11%. The numbers who had ever taken designer drugs were 3% for middle school pupils and 4% from high school. Conclusions. 1) Adolescent drug consumption has increased, particularly in those of older age and in boys. 2) Despite the only brief interval for which designer drugs were legal, they have gained high popularity among the young. 3) Adolescents have insufficient knowledge about the dangers of using DDs. 4) Faced with the growing threat of a dynamic designer drug market, appropriate counter-measures in education and prevention are therefore necessary.

    These days young people use internet as a source of information. Internet offers knowledge that can be used not only for school education but also to obtain information about usage and effects of psychoactive substances. Recent research shows that young people more often use internet websites and chat rooms to exchange knowledge and experience with chemicals and everyday products used as intoxicants, for example: nutmeg, nonprescription medications, metal cleaning liquid or feminine hygiene products. This article shows the extend of knowledge young people can gain from popular internet websites. Information on the web is presented as appealing, attractive and encouraging. From a toxicologist point of view it is extremely important to be familiar with those new threats because more and more often we have to treat young patients with a serious poisoning from usage of experimental intoxicating substances.

    To estimate the prevalence of psychoactive substances (SPA) use in young people in an educational institution in Jamundí and possible related factors. Cross-sectional study, analytical approach that simulates cases and controls, was conducted in an educational institution in Jamundí-Valley. The sample was composed of 146 students selected through simple random probability sampling without replacement. Participants individually and anonymously completed a questionnaire to identify SPA consumption and associated factors, including APGAR scale to measure family functioning. The data extracted from the questionnaires were entered into a matrix in Microsoft Excel and processed in EpiInfo version 5.0 and Stata. Descriptive analysis was performed, and a multivariate analysis was performed using unconditional logistic regression. Current consumption of SPA, 35%; age of first use was 10 to 13 years; the prevalence of drug misuse by gender was 34% for girls and 37% in boys. The most consumed legal substance was alcohol 34%, and illegal 3%. The most significant associations with the use of psychoactive substances was; having severe family dysfunction (OR=7.32; 95%CI, 1.74-30.76), being enrolled in the 11th grade (OR=14.6; 95%CI, 2.37-89.74), and having friends who use (OR=3.12; 95%CI, 2.49-10.38). The results obtained in this study show a high percentage of SPA consumption, with a higher prevalence in males. In this population, the most commonly used legal substance is alcohol. Family dysfunction and school grade were significantly associated with drug misuse. Copyright © 2015 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España. All rights reserved.

    Full Text Available In recent years in the world there is a tendency of quantity of persons who use drugs increase. Free availability of drugs of different groups for population is the main cause. Another trend associated with the consumption of drugs. All these factors led to the increased frequency of psychosis occurrence among consumers of psychoactive substances. In structure of such psychosis there are a variety of symptoms and syndromes. And since the number of drug users is quite broad in its structure - there are also persons with mental illness. This gives number of diagnostic difficulties. In this regard, the aim of the study was to trace the modern ideas of differential diagnosis of schizophrenia-like psychosis disorders due to the drug use. Materials and methods of research. In this work the content analysis of the modern representations of differential diagnosis of schizophrenia-like psychosis disorders as a result of the use of psychoactive substances was made. The problem of determination of primary and secondary nature of drug addiction in patients with psychotic disorders was indicated. Etiology and psychopathogenesis hypotheses of the addiction from psychoactive substances in the context of their correlation with endogenous mental pathology were defined. In the literature there is no clear diagnostic criteria that would allow distinguishing psychosis due to the use of drugs and endogenous psychosis, which is combined with the admission medicines. However, the attention of clinicians should be concentrated on the premorbid condition: the presence of hereditary family history, pathological behavior in childhood and adolescence. It was found that the majority of substances may cause one or more syndromes - delirium, dementia, and amnestic syndrome, delusional syndrome, hallucinatory syndrome, depressive syndrome, anxiety, and personality disorder, such disorders as schizophrenia-like psychosis disorders are not rare. Special attention was paid to the

    The quantification of illicit drug and pharmaceutical residues in sewage has been shown to be a valuable tool that complements existing approaches in monitoring the patterns and trends of drug use. The present work delineates the development of a novel analytical tool and dynamic workflow for the analysis of a wide range of substances in sewage-based samples. The validated method can simultaneously quantify 51 target psychoactive substances and pharmaceuticals in sewage-based samples using an off-line automated solid phase extraction (SPE-DEX) method, using Oasis HLB disks, followed by ultra-high performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UHPLC-QTOF) in MS{sup e}. Quantification and matrix effect corrections were overcome with the use of 25 isotopic labeled internal standards (ILIS). Recoveries were generally greater than 60% and the limits of quantification were in the low nanogram-per-liter range (0.4–187 ng L{sup −1}). The emergence of new psychoactive substances (NPS) on the drug scene poses a specific analytical challenge since their market is highly dynamic with new compounds continuously entering the market. Suspect screening using high-resolution mass spectrometry (HRMS) simultaneously allowed the unequivocal identification of NPS based on a mass accuracy criteria of 5 ppm (of the molecular ion and at least two fragments) and retention time (2.5% tolerance) using the UNIFI screening platform. Applying MS{sup e} data against a suspect screening database of over 1000 drugs and metabolites, this method becomes a broad and reliable tool to detect and confirm NPS occurrence. This was demonstrated through the HRMS analysis of three different sewage-based sample types; influent wastewater, passive sampler extracts and pooled urine samples resulting in the concurrent quantification of known psychoactive substances and the identification of NPS and pharmaceuticals. - Highlights: • A novel reiterative workflow

    In the most recent edition of Diagnostic and Statistical Manual (DSM) that is DSM-5 many modifications have been made in substance use disorder section. These include changes in terminology; sections and categories; diagnostic criteria; threshold for diagnosis; severity; and specifier. Additionally, there have been certain additions and omissions from the earlier version. Critical evaluation of the changes made to the section on disorders related to use of psychoactive substances in India context has not been published so far. The current paper presents a critique of the changes made to the substance use disorder section in DSM-5. The rationale for these changes put forth by DSM-5 work group on substance related disorders have been discussed. Additionally, attempt has been made to highlight the possible future challenges consequent to the current nosological revision for substance use disorder category. Overall DSM-5 seems to be promising in fulfilling its goal of DSM-ICD harmonisation and movement towards an internationally compatible and practical diagnostic system for mental health disorders. It has increased the scope of addiction by inclusion of behavioural addiction. It has also tried to balance the categorical and dimensional approach to diagnosis. However, the real test of this newer edition of one of the most commonly used nosological systems will be during clinical care and research. This will help address the debatable issues regarding the changes that DSM-5 brings with it.

    New psychoactive substances (NPS), often referred to as "legal highs" or "designer drugs", are derivatives and analogues of existing psychoactive drugs that are introduced in the recreational market to circumvent existing legislation on drugs of abuse. This systematic review aims to gather the state of the art regarding chemical, molecular pharmacology and toxicological information of opioid class of NPS. Chemical, pharmacological, toxicological and clinical effects of opioid class of NPS were searched in books and in PubMed (U.S. National Library of Medicine) without a limiting period. Within this class, fentanyl analogues are among the most frequently abused and pose several clinical concerns and therefore will be thoroughly discussed. Other opioid sub-categories of NPS frequently misused include AH-7921, MT-45, U-47700, U-50488, desomorphine, mitragynine, tramadol, tapentadol, salvinorin A and its analogue herkinorin. Due to inefficient monitoring techniques, as well as limited knowledge regarding the acute and long-term effects of opioids NPS, further clinical and forensic toxicological studies are required.

    A feature of human culture is that we can learn to consume chemical compounds, derived from natural plants or synthetic fabrication, for their psychoactive effects. These drugs change the mental state and/or the behavioral performance of an individual and can be instrumentalized for various purposes. After the emergence of a novel psychoactive substance (NPS) and a period of experimental consumption, personal and medical benefits and harm potential of the NPS can be estimated on evidence base. This may lead to a legal classification of the NPS, which may range from limited medical use, controlled availability up to a complete ban of the drug form publically accepted use. With these measures, however, a drug does not disappear, but frequently continues to be used, which eventually allows an even better estimate of the drug's properties. Thus, only in rare cases, there is a final verdict that is no more questioned. Instead, the view on a drug can change from tolerable to harmful but may also involve the new establishment of a desired medical application to a previously harmful drug. Here, we provide a summary review on a number of NPS for which the neuropharmacological evaluation has made important progress in recent years. They include mitragynine ("Kratom"), synthetic cannabinoids (e.g., "Spice"), dimethyltryptamine and novel serotonergic hallucinogens, the cathinones mephedrone and methylone, ketamine and novel dissociative drugs, γ-hydroxybutyrate, γ-butyrolactone, and 1,4-butanediol. This review shows not only emerging harm potentials but also some potential medical applications.

    "Synthacaine" is a New Psychoactive Substance which is, due to its inherent psychoactive properties, reported to imitate the effects of cocaine and is therefore consequently branded as "legal cocaine". The only analytical approach reported to date for the sensing of "Synthacaine" is mass spectrometry. In this paper, we explore and evaluate a range of potential analytical techniques for its quantification and potential use in the field screening "Synthacaine" using Raman spectroscopy, presumptive (colour) testing, High Performance Liquid Chromatography (HPLC) and electrochemistry. HPLC analysis of street samples reveals that "Synthacaine" comprises a mixture of methiopropamine (MPA) and 2-aminoindane (2-AI). Raman spectroscopy and presumptive (colour) tests, the Marquis, Mandelin, Simon's and Robadope test, are evaluated towards a potential in-the-field screening approach but are found to not be able to discriminate between the two when they are both present in the same sample, as is the case in the real street samples. We report for the first time a novel indirect electrochemical protocol for the sensing of MPA and 2-AI which is independently validated in street samples with HPLC. This novel electrochemical approach based upon one-shot disposable cost effective screen-printed graphite macroelectrodes holds potential for in-the-field screening for "Synthacaine".

    New psychoactive substances (NPS) have hedonic effects that may lead to dependence. Headshops selling NPS increased in number in Ireland from late 2009. Legislation was enacted in May and August of 2010 that caused their closure. It is unknown whether such events impact the rate of NPS use disorders. We conducted a population-based study using the Irish national database of episodes of addiction treatment between 2009 and 2012. We examined trends in the rate of NPS-related treatment episodes among young adults. Joinpoint trend analysis software was used to identify significant changes in trend. Of the 31 284 episodes of addiction treatment commenced by adults aged 18 to 34 years, 756 (2.4%) were NPS related. In 2012, the 12-month moving average rate had fallen 48% from its peak in 2010, from 9.0/100 000 to 4.7/100 000. Joinpoint analysis indicated that the rate of NPS related episodes increased by 218% (95% confidence interval 86 to 445, P = 0.001) every 4 months until the first third of 2010. From that point, the rate declined by 9.8% (95% confidence interval -14.1 to -5.4, P = 0.001) per 4-month period. There was no significant trend change in the rate of non-NPS related treatment episodes. Over the 2 years after the enactment of prohibition-styled legislation targeting NPS and headshops, the rate of NPS related addiction treatment episodes among young adults declined progressively and substantially. We found no coinciding trend change in the rate of episodes linked to other drug groups. [Smyth BP, Lyons S, Cullen W.

    The objectives of this study are to describe an emergency department (ED) adult population with the chief complaint of mental and behavioral disorders due to psychoactive substance use and to investigate sex- and age-related differences. We analyzed data (2009-2011) from the Regional Observatory of Emergency Medicine ORU-MiP (700000 patients per year) for all patients with a primary diagnosis of mental and behavioral disorders due to psychoactive substance use. Day data were weighted by the number of days in the year and expressed for 100000 inhabitants of the area. Pearson χ(2) test and Fisher tests were used. The Brown-Mood test was used to compare medians. Of the 1411597 ED visits analyzed, 20838 consults (1.3%) were for primary diagnosis of mental and behavioral disorders due to psychoactive substance use. The median age (interquartile range) was 41 (28-51) years; 69.5% were men. More women consulted the ED for sedative or hypnotic use (4.9% vs 1.5%, P consumption (93.5% vs 90%, P psychoactive substance use account for 1.3% of ED visits. Older people should be screened for chronic alcohol consumption. Our findings underscore the opportunity provided by the ED for screening and brief intervention in drug- and alcohol-related problems.

    The number of newly reported psychoactive substances in Europe is now higher than ever. In order to evade legal restrictions, old and novel psychoactive substances from medical research and their derivatives are commonly mislabeled as "not for human consumption" and offered for sale on the Internet and elsewhere. Such substances are widely taken by young people as "club drugs." Their consumption must be considered in the differential diagnosis of psychiatric, neurological, cardiovascular, or metabolic disturbances of unclear origin in a young patient. Selective review of pertinent literature retrieved by a PubMed search, including publications by government-sponsored organizations. From 2010 to 2012, 163 substances were reported to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), mostly either synthetic cannabinoids (39.3%) or synthetic cathinones (16.6%). Synthetic cannabinoids alter mood and perception; intoxications cause agitation, tachy cardia, and arterial hypertension. Synthetic cathinones are hallucinogenic stimulants with predominantly cardiovascular and psychiatric side effects. Severe intoxications cause serotonin syndrome and potentially fatal rhabdomyolysis. Substances in either of these classes often escape detection in screening tests. Young persons who present with agitation and cardiovascular and/or psychiatric manifestations of unclear origin and whose drug screening tests are negative may be suffering from an intoxication with a novel psychoactive substance. Physicians should know the classes of such substances and their effects. Targeted toxicological analysis can be carried out in a toxicology laboratory or a facility for forensic medicine.

In the paper the authors study family characteristics which influence family health and diseases, indicators of family health and the scale of life values. Also, the study evaluates social factors, communication and the influence of the usage of psychoactive substances on family health and the quality of family life. To form the personality of a child three factors are most significant: love, the feeling of safety and the presence of harmonious relationship between the parents. Life harmony in a family also depends on the quality of structural components of the personality and the interaction of motivation of its members. Early childhood determines the future personality of the adult person. At that period, habits and partially attitudes are formed. In harmonious family relationships the parents are the role model to children. Verbal and non-verbal communication enrich the relationship among people and enable efforts in supporting understanding, compassion and care for others by mutual agreement. On the scale of life values of Serbian citizens health holds the first position. Immediately following the health issue is good relationship in the family. As healthcare is not only the task of healthcare services, but also of each individual, family and the society as a whole, it is on healthcare personnel to educate the citizens how to preserve and improve their own health and the health of their family by a continual healthcare and education. Above all, this concerns avoidance of bad habits, such as smoking, immoderate alcohol consumption, narcotic abuse, physical inactivity, hypercaloric nutrition, etc. Also, it is significant to make an early recognition of disease symptoms and to turn for

    Recreational drug toxicity is frequent. Availability of new psychoactive substances is steadily increasing. However, data with verified analyses from clinical settings are limited. To evaluate the impact of novel psychoactive substances (NPS) on recreational drug toxicity in Oslo, Norway, we analysed samples from a selection of patients. All the patients presenting with recreational drug toxicity at the Oslo Accident and Emergency Outpatient Clinic (OAEOC) and at the Oslo University Hospital (OUH) were registered from April through September 2014. Oral fluid samples were collected at the OAEOC. Blood samples were collected at the OUH. The samples were screened using ultra-high performance liquid chromatography - tandem mass spectrometry (UHPLC-MS/MS). Nine hundred and sixty-four cases were included, 841 (87.2%) at the OAEOC and 123 (12.8%) at the OUH. A total of 55 oral fluid samples (OAEOC) and 103 blood samples (OUH) could be analysed. NPS were not clinically suspected in any of the screened cases. At the outpatient clinic, the most commonly found substances were clonazepam in 42/55 (76.4%) cases, amfetamines in 40/55 (72.7%) and heroin in 39/55 (70.9%). In seven (12.7%) cases NPS were detected: 4-methylamfetamine in three cases, dimethyltryptamine in two, methylone in one, and N,N-dimethyl-3,4-methylenedioxyamfetamine in one. Among the hospital patients, the most commonly found substances were clonazepam in 51/103 (49.5%) cases, amfetamines in 48/103 (46.6%), heroin in 31/103 (30.1%), and diazepam in 30/103 (29.1%). In five (4.9%) cases NPS were detected: JWH-210 in two cases, AM-2201 in two, and 5-EAPB in one. NPS were clinically not suspected, though found in eight percent of cases. Still, the vast majority of patients treated for recreational drug toxicity in Oslo have taken classical drugs. Management of these patients should be based on their clinical condition. However, it is highly important to be alert to atypical presentations possibly resulting from

    Kosmicare project implements crisis intervention in situations related to the use of psychoactive substances at Boom Festival (Portugal). We present evaluation research that aims to contribute to the transformation of the project into an evidence-based intervention model. It relies on harm reduction and risk minimization principles, crisis intervention models, and Grof's psychedelic psychotherapy approach for crisis intervention in situations related to unsupervised use of psychedelics. Intervention was expected to produce knowledge about the relation between substance use and mental health impact in reducing potential risk related to the use of psychoactive substances and mental illness, as well as an impact upon target population's views of themselves, their relationship to substance use, and to life events in general. Research includes data on process and outcome indicators through a mixed methods approach, collected next to a sample of n=176 participants. Sample size varied considerably, however, among different research measures. 52% of Kosmicare visitors reported LSD use. Over 40% also presented multiple drug use. Pre-post mental state evaluation showed statistically significant difference (p<.05) confirming crisis resolution. Crisis episodes that presented no resolution were more often related with mental health outburst episodes, with psychoactive substance use or not. Visitors showed high satisfaction with intervention (n=58) and according to follow-up (n=18) this perception was stable over time. Crisis intervention was experienced as very significant. We discuss limitations and implications of evaluating natural setting based interventions, and the relation between psychoactive substance use and psychopathology. Other data on visitor's profile and vulnerability to crisis showed inconclusive.

    Numbers of novel psychoactive substances (NPS) have been rapidly increasing over the past few years, with unprecedented challenges on traditional drug control systems. The web has been involved in the promotion and knowledge dissemination of NPS, which are being presented online as safer/legal alternatives to illicit drugs. The physical, psychological and social harms associated with NPS have been studied so far mainly in Europe and other English speaking countries. The aim of this research is to provide knowledge on the provision of NPS information/purchase opportunities to Middle East customers, whilst monitoring the Internet in Arabic and Farsi. Web analysis/assessments were carried out in both Farsi and Arabic between 2011 and 2013. Sources were scrutinized with the help of different search engines, including Google Arabic and Google Persian, to carry out searches focusing on both NPS retailers' and social network websites. The research identified 45 NPS apparently offered for purchase online. Most of these products were of synthetic origin; a few herbal stimulants were identified as well. The pro drug websites were not here easily identified, being hidden behind other, unrelated, websites. Present results may constitute a public health challenge to be considered at both national and worldwide level. New legislative frameworks should also be encouraged in order to ensure a better response to the current threat posed by rapid emergence of these substances. Copyright © 2014 Elsevier B.V.

    Novel psychoactive substances (NPS) are new psychotropic drugs, not scheduled under the International Conventions on Psychotropic Substances, but which may pose a relevant public health threat. In this study, we investigated knowledge and use of NPS in a sample of Italian youth in urban and rural areas. Between December 2012 and October 2013, we administered a questionnaire to a sample of 3011 healthy subjects (44.7% men; 55.3% women), aged between 16 and 24 years and recruited in urban, intermediate and rural areas of Italy. Of the global sample, 53.3% declared to have some knowledge on NPS, with a higher knowledge in urban areas. Mephedrone (26%), desomorphine (22.6%) and methamphetamine (21.7%) were the most commonly known drugs. NPS use was reported by 4.7% of the sample, without significant differences between urban and rural areas; mephedrone (3.3%), synthetic cannabinoids (1.2%) and Salvia divinorum (0.3%) consumption has been identified. NPS use was also predictive of binge-drinking behaviours (χ(2) (4) = 929.58, p < .001). Urban areas may represent a focal point for preventive strategies, given the presence of higher levels of NPS knowledge. Moreover, the association between binge-drinking habits and NPS use was really strong. This issue should not be underestimated because of its medical, psychopathological and social consequences.

    Recently, there has been a worldwide substantial increase in the consumption of new psychoactive substances (NPS), compounds that mimic the structure of illicit drugs, such as amphetamines or ecstasy. The producers try to avoid the law by a slight modification of illicit structures, thereby developing dozens of temporarily legal NPS every year. The current trends in the detection and monitoring of such substances demand a fast and reliable analysis. Molecular spectroscopy represents a highly effective tool for the identification of NPS and chiroptical methods can provide further information on their 3D structure, which is the key for the determination of their biological activity. We present the first systematic study of NPS, specifically butylone, combining chiroptical and vibrational spectroscopies with ab initio calculations. According to density functional theory calculations, 6 stable lowest energy conformers of butylone were found and their molecular structure was described. For each conformer, the relative abundance based on the Boltzmann distribution was estimated, their population weighted spectra predicted and compared to the experimental results. Very good agreement between the experimental and the simulated spectra was achieved, which allowed not only the assignment of the absolute configuration, but also a precise description of the molecular structure. © 2018 Wiley Periodicals, Inc.

    To know the pattern of use of new psychoactive substances (NPSs) in a Spanish sample of research chemical (RC) users and to deepen the RC user profile and risk reduction strategies employed. This study is a cross-sectional survey by means of a specific questionnaire. Recruitment was carried out at music festivals, at non-governmental organizations (NGOs), and through announcements on an online forum. Two RC user profiles were defined, according to whether they search information through online forums. A total of 230 users participated. The most frequent RCs were hallucinogenic phenethylamines (2C-B 80.0%, 2C-I 39.6%) and cathinones (methylone 40.1%, mephedrone 35.2%). The most frequent combination of RC with other illegal drugs was with cannabis (68.6%) and 2C-B with MDMA (28.3%). Subjects who are consulting drug forums (group 1) use more RC, obtain RC by Internet, and use more frequently risk prevention strategies. Regarding the risk-reduction strategies in this group, users sought information concerning RC before consuming them (100%), used precision scales to calculate dosage (72.3%), and analyzed the contents before consumption (68.8%). There is a specific RC user profile with extensive knowledge and consumption of substances, using different strategies to reduce risks associated to its consumption.

    Full Text Available The consumption of psychoactive substances (PAS is a public health problem in Colombia andworldwide. The people who consume such substances are becoming younger, and their effectsare potentially harmful and may affect all areas of adjustment of the individual. Although it hasbeen conceived that way, the use of PAS is not always associated with personal problems or highdegrees of stress. There may be other motivations associated. Objective: The objectives of thisarticle are to present: (a the relative frequency of consumption of PAS among college students,(b which are the PAS consumed most by college students and differences in their consumptionby sex and by age, (3 the relationship between the consumption of PAS and contexts of diversion.Materials and methods: This is a descriptive correlational study derived from an Italian researchproject, in which the sample were 226 college students from four undergraduate programs ofa private university in Bogotá DC, selected using a stratified random sampling procedure withproportional allocation. Participants filled out a questionnaire. Results: The PAS with the highestconsumption were alcohol, nicotine and marijuana. Males predominantly showed an increasedconsumption. The results are consistent with the national trend. Conclusion: The consumptionof SPA among college students is high and some recreational contexts are closely associated withthis behaviour.

    Data on psychoactive substance (PAS) consumption among adolescents in the North Center of Morocco are not at all available. Therefore, the current study aimed at investigating the prevalence and the determinants of psychoactive substances use among middle and high school students in this region. A cross-sectional study was conducted from April 2012 to November 2013 in public middle and high schools in the North Central Region of Morocco. An anonymous self-administered questionnaire was used to assess psychoactive substances use among a representative sample of school students from the 7th to the 12th grade, aged 11-23 years, selected by stratified cluster random sampling. Factors associated with psychoactive substance use were identified using multivariate stepwise logistic regression analyses. A total of 3020 school students completed the questionnaires, 53.0 % of which were males. The overall lifetime smoking prevalence was 16.1 %. The lifetime, annual and past month rates of any psychoactive substance use among the study subjects were 9.3, 7.5, and 6.3 % respectively. Cannabis recorded the highest lifetime prevalence of 8.1 %, followed by alcohol 4.3 %, inhalants 1.7 %, psychotropic substances without medical prescription 1.0, cocaine 0.7, heroine 0.3, and amphetamine with only 0.2 %. Psychoactive substance use was associated with males more than females. The risk factors identified by multivariate stepwise logistic regression analyses were being male, studying in secondary school level, smoking tobacco, living with a family member who uses tobacco, and feeling insecure within the family. The prevalence among all school students reported by the current study was comparable to the national prevalence. Efforts to initiate psychoactive substance prevention programs among school students should be made by designing such programs based on the significant factors associated with psychoactive substance use identified in this study.

    Alpha-methyltryptamine (AMT) is a novel psychoactive substance available over the Internet. This study used European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) Internet snapshot methodology to investigate the availability and cost of AMT in March/October 2012. From March to October 2012, there was a decrease in the number of Internet sites selling AMT (44 to 31). AMT powder was cheaper in "bulk" (100 g) than in "recreational-user" (100 mg) quantities, and there was a decrease in price. Data from Internet snapshot surveys complement and allow triangulation of data from other sources to build a more detailed picture on availability and use of novel psychoactive substances.

  16. Mood Fluctuation and Psychobiological Instability: The Same Core Functions Are Disrupted by Novel Psychoactive Substances and Established Recreational Drugs

    Directory of Open Access Journals (Sweden)

    Andrew C. Parrott

    2018-03-01

    Full Text Available Many novel psychoactive substances (NPS have entered the recreational drug scene in recent years, yet the problems they cause are similar to those found with established drugs. This article will debate the psychobiological effects of these newer and more traditional substances. It will show how they disrupt the same core psychobiological functions, so damaging well-being in similar ways. Every psychoactive drug causes mood states to fluctuate. Users feel better on-drug, then feel worse off-drug. The strength of these mood fluctuations is closely related to their addiction potential. Cyclical changes can occur with many other core psychobiological functions, such as information processing and psychomotor speed. Hence the list of drug-related impairments can include: homeostatic imbalance, HPA axis disruption, increased stress, altered sleep patterns, neurohormonal changes, modified brain rhythms, neurocognitive impairments, and greater psychiatric vulnerability. Similar patterns of deficit are found with older drugs such as cocaine, nicotine and cannabis, and newer substances such as 3,4-methylenedioxymethamphetamine (MDMA, mephedrone and spice. All psychoactive drugs damage human well-being through similar basic neuropsychobiological mechanisms.

    The aim of this study was to identify factors associated with the results of smoking cessation attempts. Data were collected in Clermont-Ferrand from a smoking cessation clinic between 1999 and 2009 (1,361 patients). Smoking cessation was considered a success when patients were abstinent 6 months after the beginning of cessation. Multivariate logistic regression was used to investigate the association between abstinence and different factors. The significant factors were a history of depression (ORadjusted = 0.57, p = 0.003), state of depression at the initial consultation (ORa = 0.64, p = 0.005), other psychoactive substances (ORa = 0.52, psuccess was four times higher). A high score in the Richmond test had a greater impact on success with increasing age (significant interaction: p = 0.01). In exclusive smokers, the contemplation level in the Prochaska algorithm was enough to obtain a satisfactory abstinence rate (65.5%) whereas among consumers of other psychoactive substances, it was necessary to reach the preparation level in the Prochaska algorithm to achieve a success rate greater than 50% (significant interaction: p = 0.02). The psychological preparation of the smoker plays a critical role. The management of smoking cessation must be personalized, especially for consumers of other psychoactive substances and/or smokers with a history of depression.

    Full Text Available A literature search reveals no studies concerning simultaneous identification of commonly abused drugs, benzodiazepines, and new psychoactive substances in urine by liquid chromatography tandem mass spectrometry (LC–MS/MS. We developed and validated an LC–MS/MS method for simultaneous identification of multiple abused drugs, benzodiazepines, and new psychoactive substances in urine from suspected drug abusers. The instrument was operated in multiple-reaction monitoring using an electrospray ionization mode. Chromatograms were separated using an ACE5 C18 column on a gradient of acetonitrile. After liquid–liquid extraction, samples were passed through a 0.22-μm polyvinylidene difluoride filter before injection into the LC–MS/MS. The limits of quantitation ranged from 0.5 ng/mL to 31.3 ng/mL. The linearity ranged from 0.5 ng/mL to 200 ng/mL. The precision results were below 15.4% (intraday and 18.7% (interday. The intraday accuracy ranged from 85.9% to 121.0%; interday accuracy ranged from 66.1% to 128.7%. The proposed method was applied to 769 urine samples. The most common three drugs identified were ketamine, amphetamine, and opiates. The drug positive rate for one or more drugs was 79.6%. Our results demonstrate the suitability of the LC–MS/MS method for simultaneous identification of multiple abused drugs, benzodiazepines, and new psychoactive substances in urine.

  19. Drug policy and global regulatory capitalism: the case of new psychoactive substances (NPS).

    Seddon, Toby

    2014-09-01

    The recent emergence of vibrant markets in 'new psychoactive substances' or 'legal highs' has posed significant new challenges for drug policy. These partly concern what to do about them but the speed and complexity of change has also raised difficulties for how policy responses should be developed. Existing drug policy systems appear too slow and cumbersome to keep up with the pace of change, remaining locked in large part within 'old' ways of thinking that centre almost exclusively around the deployment (or not) of the criminal law and its related enforcement apparatus. In this paper, it is argued that we need to rethink the problem through the lens of regulation, in order to learn lessons from other sectors where more agile responses to changing markets and business innovation have often proved possible. By examining examples drawn from these other areas, an alternative policy-making framework can be developed, involving a more flexible mix of state regulation, civil society action and private law mechanisms. This new approach is founded on a recognition of the networked and polycentric character of effective market governance in an era of global regulatory capitalism. Copyright © 2014 Elsevier B.V.

    Full Text Available Benzylpiperazine (BZP is a novel psychoactive substance that is commonly abused in tablet form as an “ecstasy-type” drug. Electroanalysis offers genuine potential for field testing of bulk drug samples. This research is the first to investigate the viability of voltammetric analysis of BZP. Initial cyclic voltammetry in 0.1 M KCl showed an oxidative peak at a glassy carbon electrode for BZP at approximately 0.8 V (scan rate 205 mV s−1. Next an optimised electrode/electrolyte combination (viz. 80:20 W:W glassy carbon beads:nujol and pH 9.5, 40 mM, Britton-Robinson buffer was developed using K3Fe(CN6 to test the electrode material. The oxidation of BZP involves two electrons and two protons and a mechanism has been proposed. An anodic stripping square wave voltammetric method was optimised by factorial design with the conditions of deposition: −0.8 V for 135 s, and stripping: step height 10 mV, amplitude 50 mV and frequency 13 Hz. A limit of detection of 6 μM was achieved. The resolution against 3,4-methylenedioxymethylamphetamine (MDMA was also verified.

The primary objective of this research was to document types of NPS for sale on the largest operating Tor site (Agora) over a period of four months. Secondary objectives were to analyze countries and vendors sourcing NPS on Agora. Data from Agora were collected in February and June 2015. The number of total advertisements on Agora increased from 20,742 to 27,431 over the four months, while the number of NPS advertisements increased from 2,205 to 2,271 and the number of vendors increased from 157 to 288. The composition of NPS listings and source countries for NPS advertised on Agora diversified over time. Advertisements for ketamine and unclassified NPS experienced substantial growth, while the availability of phenethylamines decreased. However, phenethylamines remained the most frequently advertised NPS type. China and the U.S. were found to be the top two countries by volume selling NPS on Agora over the fpir months, but the number of countries identified as advertising NPS increased by nearly 43%. The United States housed the most NPS vendors.

    Analysis of drug residues in urban wastewater could complement epidemiological studies in detecting the use of new psychoactive substances (NPS), a continuously changing group of drugs hard to monitor by classical methods. We initially selected 52 NPS potentially used in Italy based on seizure data and consumption alerts provided by the Antidrug Police Department and the National Early Warning System. Using a linear ion trap-Orbitrap high resolution mass spectrometer, we designed a suspect screening and a target method approach and compared them for the analysis of 24 h wastewater samples collected at the treatment plant influents of four Italian cities. This highlighted the main limitations of these two approaches, so we could propose requirements for future research. A library of MS/MS spectra of 16 synthetic cathinones and 19 synthetic cannabinoids, for which analytical standards were acquired, was built at different collision energies and is available on request. The stability of synthetic cannabinoids was studied in analytical standards and wastewater, identifying the best analytical conditions for future studies. To the best of our knowledge, these are the first stability data on NPS. Few suspects were identified in Italian wastewater samples, in accordance with recent epidemiological data reporting a very low prevalence of use of NPS in Italy. This study outlines an analytical approach for NPS identification and measurement in urban wastewater and for estimating their use in the population.

    There is a lack of information regarding the use of novel psychoactive substances (NPS) in Western Australia. The aim of this study was to pilot-test an online survey to obtain data on the prevalence of NPS and other drug use by young Western Australians aged between 18 and 35 years. The Young Adult Drug and Alcohol Survey (YADAS) was a questionnaire deployed online for a period of six months. Participants were recruited via a combined targeted sampling and snowball methodology. There were 472 valid responses. Overall lifetime use of NPS was relatively high (17.6%), while use in the last year was lower (6.6%). These proportions were comparable to that of cocaine use. The most popular NPS were the synthetic cannabinoids. The proportions of respondents drinking alcohol at risky levels, mixing alcohol with energy drinks, and using pharmaceuticals such as ADHD medications for non-medical reasons were high. The YADAS is the first survey to ascertain the prevalence of use of numerous types of NPS in a large sample of young Western Australian adults. The utilization of an online survey methodology yielded valid results as compared to more intensive surveys, and enables researchers greater flexibility in being able to capture current trends.

  4. New psychoactive substances: an overview on recent publications on their toxicodynamics and toxicokinetics.

    This review article covers English-written and PubMed-listed review articles and original studies published between January 2015 and April 2016 dealing with the toxicodynamics and toxicokinetics of new psychoactive substances. Compounds covered include stimulants and entactogens, synthetic cannabinoids, tryptamines, NBOMes, phencyclidine-like drugs, benzodiazepines, and opioids. First, an overview and discussion is provided on timely review articles followed by an overview and discussion on recent original studies. Both sections are then concluded by an opinion on these latest developments. This review shows that the NPS market is still highly dynamic and that the data published on their toxicodynamics and toxicokinetics can hardly keep pace with the appearance of new entities. However, data available are very helpful to understand and predict how NPS may behave in severe intoxication. The currently best-documented parameter is the in vitro metabolism of NPS, a prerequisite to allow detection of NPS in biological matrices in cases of acute intoxications or chronic consumption. However, additional data such as their chronic toxicity are still lacking.

    Opiate addiction remains a major threat to public health worldwide. It also had a number of negative consequences for the psychosocial and economic functioning of abusers. One of the most common addiction treatment method is maintenance methadone therapy. An important part of evaluating the effectiveness of the participation of a person addicted to methadone treatment is to assess the quality of life determined by participation in substitution therapy. Quality of life of persons addicted to psychoactive substances determined by socio-demographic situation. The study involved 234 outpatient addicts included in the methadone maintenance treatment programs in Szczecin, Warsaw and Lublin. It was based on a diagnostic survey performed using an original questionnaire and the SF-36 v2. In a research of subjective qual- ity of life, respondents obtained results at the level sufficient, higher values were obtained in the domains of physical than mental health. Respondents from Szczecin and Warszawa scored higher, statistically significant, the assessment than patients from Lublin. 1. Variation of respondents quality of life was conditioned by the place of performance of therapy. 2. Respondents had the greatest disparity in the subjective evaluation of physical and mental health. 3. Age was an important factor affecting the marks obtained by the respondents in the SF-36 v2.

    Among novel psychoactive substances notified to EMCDDA and Europol were 1-cyclohexyl-x-methoxybenzene stereoisomers (ortho, meta, and para). These substances share some structural characteristics with phencyclidine and tramadol. Nowadays, no information on the pharmacological and toxicological effects evoked by 1-cyclohexyl-x-methoxybenzene are reported. The aim of this study was to investigate the effect evoked by each one stereoisomer on visual stimulation, body temperature, acute thermal pain, and motor activity in mice. Mice were evaluated in behavioral tests carried out in a consecutive manner according to the following time scheme: observation of visual placing response, measures of core body temperature, determination of acute thermal pain, and stimulated motor activity. All three stereoisomers dose-dependent inhibit visual placing response (rank order: meta > ortho > para), induce hyperthermia at lower and hypothermia at higher doses (meta > ortho > para) and cause analgesia to thermal stimuli (para > meta = ortho), while they do not alter motor activity. For the first time, this study demonstrates that systemic administration of 1-cyclohexyl-x-methoxybenzene compounds markedly inhibit visual response, promote analgesia, and induce core temperature alterations in mice. This data, although obtained in animal model, suggest their possible hazard for human health (i.e., hyperthermia and sensorimotor alterations). In particular, these novel psychoactive substances may have a negative impact in many daily activities, greatly increasing the risk factors for workplace accidents and traffic injuries.

    Hundreds of new psychoactive substances (NPS) have emerged in the drug market over the last decade. Few drug surveys in the USA, however, ask about use of NPS, so prevalence and correlates of use are largely unknown. A large portion of NPS use is unintentional or unknown as NPS are common adulterants in drugs like ecstasy/Molly, and most NPS are rapidly eliminated from the body, limiting efficacy of urine, blood and saliva testing. We utilized a novel method of examining prevalence of NPS use in a high-risk population utilizing hair-testing. Hair samples from high-risk nightclub and dance music attendees were tested for 82 drugs and metabolites (including NPS) using ultra-high performance liquid chromatography-tandem mass spectrometry. Eighty samples collected from different parts of the body were analyzed, 57 of which detected positive for at least one substance-either a traditional or new drug. Among these, 26 samples tested positive for at least one NPS-the most common being butylone (25 samples). Other new drugs detected include methylone, methoxetamine, 5/6-APB, α-PVP and 4-FA. Hair analysis proved a powerful tool to gain objective biological drug-prevalence information, free from possible biases of unintentional or unknown intake and untruthful reporting of use. Such testing can be used actively or retrospectively to validate survey responses and inform research on consumption patterns, including intentional and unknown use, polydrug-use, occasional NPS intake and frequent or heavy use. © The Author 2017.

    Syndemics of illicit drug use and HIV remain as significant public health issues around the world. There has been increasing concern regarding the rapidly growing market of new psychoactive substances, particularly in Asia. In response, the Japanese government has increasingly banned such substances in recent years. We sought to identify the prevalence and correlates of use of quasi-legal psychoactive substances among people living with HIV/AIDS (PLHIV) in Japan. Data were derived from a nationwide survey of PLHIV conducted at nine leading HIV/AIDS care hospitals between July and December 2013. The prevalence and correlates of the use of quasi-legal psychoactive substances (e.g., synthetic cannabinoids, cathinone derivatives, etc. that had not been prohibited from using at the time of survey) among male participants were examined using multivariate survey logistic regression. Among 963 study participants, the majority (95.3%) were male. The most commonly used drug among men was quasi-legal psychoactive substances (55.3% ever and 12.8% in the previous year). In multivariate analysis, the lifetime use of tryptamine-type derivatives (i.e., 5-MeO-DIPT or N,N-diisopropyl-5-methoxytryptamine) (adjusted odds ratio [AOR]: 2.42; 95% confidence interval [CI]: 1.36-4.28) and methamphetamine/amphetamine (AOR: 3.59; 95% CI: 2.13-6.04) were independently associated with recent quasi-legal psychoactive substance use. In our sample of male PLHIV in Japan, quasi-legal psychoactive substances were the most commonly used drugs. Individuals who had ever used tryptamine-type derivatives or methamphetamine/amphetamine were more likely to report recent quasi-legal psychoactive substance use, suggesting a potential shift in drug use patterns from regulated to unregulated substances among this population. These findings indicate a need for further research to examine implications for HIV care.

  9. Categorization of psychoactive substances into "hard drugs" and "soft drugs": a critical review of terminology used in current scientific literature.

    Precise terminology and definitions are important components of scientific language. Although the terms "hard drugs" and "soft drugs" are used widely by professionals, neither the International Classification of Diseases nor the Diagnostic and Statistical Manual classify psychoactive substances into the categories "hard" and "soft." To analyze the occurrence of the terms "hard drugs" and "soft drugs" in recent scientific literature and to establish the degree of consensus in labeling psychoactive substances as "hard" or "soft." A critical review of scientific papers listed in PubMed and Scopus between 2011 and 2015. Three hundred thirty-four articles were initially identified as potentially relevant for review, 132 of which were included in the final analysis. One hundred twenty-four articles used the term "hard drugs" and 84.7% provided examples of substances considered "hard." Forty-four articles used the term "soft drugs" and 90.9% provided examples of substances considered "soft." Citations of relevant articles supporting categorization as "hard" or "soft" were not given in 90% of the articles. The authors often provided no or only very sparse information on their reasons for considering specific drugs as "hard" or "soft." Although it initially appeared that there is substantial agreement as to which psychoactive substances should be regarded as "hard" and "soft," closer inspection shows that the dividing line is blurred without clear criteria for categorization. At this time, it remains uncertain whether these terms should persist in the scientific literature. We therefore recommend these terms should be avoided or, if used, be clearly and precisely defined.

  10. A systematic review of the effects of novel psychoactive substances 'legal highs' on people with severe mental illness.

    2016-06-01

    WHAT IS KNOWN ON THE SUBJECT?: Novel psychoactive substances (NPS) include synthetic drugs mimicking the effects of illicit drugs, e.g. synthetic cannabinoids, and herbs such as Salvia divinorum. NPS are substances that can trigger hallucinations and other effects altering the mind, and are currently uncontrolled by the United Nations' 1961 Narcotic Drugs/1971 Psychotropic Substances Conventions. NPS affect brain chemistry that induces the psychoactive effects, such as hallucinations and feeling 'high'. It is unknown what effects such drugs have on people with severe mental illness (i.e. psychotic illnesses). WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Our review demonstrates that little is known about the effects of various NPS on people with severe mental illness. Almost nothing is known about the long-term consequences of NPS use on the mental and physical health of SMI patients. Patients may lack understanding that NPS are psychoactive drugs that can impact on their mental and physical wellbeing. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Some patients might be reluctant or do not think it is relevant to disclose NPS use. Commonly used illicit drug screening is unlikely to detect the presence of NPS, therefore health and mental health professionals should directly enquire about NPS and actively encourage patients with severe mental illness to disclose any substance use. There was no significant patient and public involvement in the development and conduct of this study . Introduction Novel psychoactive substances (NPS) are synthetic substances that have been developed to produce altered states of consciousness and perceptions. People with severe mental illness (SMI) are more likely to use NPS than people without mental illness, but the short- and long-term effects of NPS are largely unknown. Method We systematically reviewed the literature about the effects of NPS on people with SMI. Results We included 12 case reports, 1 cross-sectional survey and 1 qualitative

    Full Text Available INTRODUCTION: In the female population, adherence to specialist clinical treatment for psychoactive substance dependence has peculiar characteristics in terms of therapeutic approaches available to addicts in general. A smaller number of women seek specialist treatment in comparison with men. Traditionally, most health care services specializing in chemical dependence provide similar therapies to both men or women, including the use of mixed-sex groups at some facilities. OBJECTIVE: To discuss the views or psychological meanings attributed by women with substance use disorders to phenomena associated with adherence to treatment at a specialist university outpatient clinic. METHODS: The qualitative-clinical method was used, i.e., an approach characterized by the typically qualitative focus of human sciences adapted to health care settings. The semi-structured interview technique with open questions was used for data collection, combined with observation of the women interviewed. Data were processed using qualitative content analysis. RESULTS: Three categories of treatment outcomes emerged: 1 significant motivations to seek and follow the treatment proposed; 2 symbolic meanings attributed to the drug; 3 psychological representations of lack of motivation to explain difficulties adhering to treatment. CONCLUSIONS: Our findings suggest that the motivations of addicted women to seek treatment vary, but highlight the fact that the substance used becomes perceived as something that causes significant losses and hinders the proper exercise of women’s role in family and social contexts. A warm welcoming is considered essential for a patient to adhere to treatment, offsetting the strong physical pleasure associated with psychoactive substance use.INTRODUÇÃO: Na população feminina, a adesão a tratamentos clínicos especializados em dependência de substâncias psicoativas tem características peculiares quando se considera as abordagens terap

  12. Abuse of Prescription Drugs in the Context of Novel Psychoactive Substances (NPS): A Systematic Review.

    Recently, a range of prescription and over-the-counter drugs have been reportedly used as Novel Psychoactive Substances (NPS), due to their potential for abuse resulting from their high dosage/idiosyncratic methods of self-administration. This paper provides a systematic review of the topic, focusing on a range of medications which have emerged as being used recreationally, either on their own or in combination with NPS. Among gabapentinoids, pregabalin may present with higher addictive liability levels than gabapentin, with pregabalin being mostly identified in the context of opioid, polydrug intake. For antidepressants, their dopaminergic, stimulant-like, bupropion activities may explain their recreational value and diversion from the therapeutic intended use. In some vulnerable clients, a high dosage of venlafaxine (‘baby ecstasy’) is ingested for recreational purposes, whilst the occurrence of a clinically-relevant withdrawal syndrome may be a significant issue for all venlafaxine-treated patients. Considering second generation antipsychotics, olanzapine appears to be ingested at very large dosages as an ‘ideal trip terminator’, whilst the immediate-release quetiapine formulation may possess proper abuse liability levels. Within the image- and performance- enhancing drugs (IPEDs) group, the beta-2 agonist clenbuterol (‘size zero pill’) is reported to be self-administered for aggressive slimming purposes. Finally, high/very high dosage ingestion of the antidiarrhoeal loperamide has shown recent increasing levels of popularity due to its central recreational, anti-withdrawal, opiatergic effects. The emerging abuse of prescription drugs within the context of a rapidly modifying drug scenario represents a challenge for psychiatry, public health and drug-control policies.

    The aim of this study was to identify the role that working conditions play in predicting the consumption of illicit psychoactive substances (IPS) among truck drivers. This cross-sectional study was conducted with truck drivers who transport grains to Paranaguá Port, PR, Brazil. The truck drivers were interviewed, and they completed a self-administered questionnaire regarding their sociodemographics, lifestyles, working conditions, and consumption of IPS over the past 30 days. The statistical analysis included logistic regression models progressively adjusted for sociodemographic and lifestyle variables. A total of 670 male drivers with a mean age of 41.9 (±11.1) years were assessed. The prevalence of IPS consumption over the past 30 days was 10.9% (n=73). The drugs used primarily consisted of amphetamines (n=61). After adjusting for working characteristics, sociodemographic and lifestyle variables, the following working conditions were associated with the consumption of IPS: driving mostly at night (OR=3.91; 95% CI 1.75 to 8.74), driving while tired (OR=2.26; 95% CI 1.31 to 3.89), and earning a higher monthly income (OR=2.08; 95% CI 1.16 to 3.72). Drivers who were 39 years old or younger (OR=2.11; 95% CI 1.05 to 4.25) and not living with a partner (OR=2.22; 95% CI 1.17 to 4.22) were also more likely to consume IPS. Driving mostly at night, being tired, and earning more increase the use of IPS among truck drivers, regardless of other working characteristics, sociodemographic, and lifestyle variables.

    2017-01-01

    New Psychoactive Substances (NPS) belong to several chemical classes, including phenethylamines, piperazines, synthetic cathinones and synthetic cannabinoids. Development and validation of analytical methods for the determination of NPS both in traditional and alternative matrices is of crucial importance to study drug metabolism and to associate consumption to clinical outcomes and eventual intoxication symptoms. Among different biological matrices, hair is the one with the widest time window to investigate drug-related history and demonstrate past intake. The aim of this paper was to overview the trends of the rapidly evolving analytical methods for the determination of NPS in hair and the usefulness of these methods when applied to real cases. A number of rapid and sensitive methods for the determination of NPS in hair matrix has been recently published, most of them using liquid chromatography coupled to mass spectrometry. Hair digestion and subsequent solid phase extraction or liquid-liquid extraction were described as well as extraction in organic solvents. For most of the methods limits of quantification at picogram per milligram hair were obtained. The measured concentrations for most of the NPS in real samples were in the range of picograms of drug per milligram of hair. Interpretation of the results and lack of cut-off values for the discrimination between chronic consumption and occasional use or external contamination are still challenging. Methods for the determination of NPS in hair are continually emerging to include as many NPS as possible due to the great demand for their detection.

    2018-02-01

    The increasing number of legally ambiguous and precarious Novel Psychoactive Substances (NPS) constitutes a challenge for policy makers and public health. Scientific and more in-depth knowledge about the motivations for using NPS is scarce and often consist of predetermined, non-systematic, or poorly described reasons deduced from top-down approaches. Therefore, the aim of the present study was to explore and characterize the users' self-reported reasons for NPS use inductively and more comprehensively. The self-reported reasons of a self-selected sample of 613 international NPS users were collected via an online survey promoted at the international drug discussion forum bluelight.org and later analyzed qualitatively using inductive thematic analysis. The analysis showed that the participants used NPS because these compounds reportedly: 1) enabled safer and more convenient drug use, 2) satisfied a curiosity and interest about the effects, 3) facilitated a novel and exciting adventure, 4) promoted self-exploration and personal growth, 5) functioned as coping agents, 6) enhanced abilities and performance, 7) fostered social bonding and belonging, and 8) acted as a means for recreation and pleasure. The consumption of NPS was also driven by 9) problematic and unintentional use. The present study contributed to a more comprehensive understanding of the users' own and self-reported reasons for using NPS, which needs to be acknowledged not only in order to minimize drug related harm and drug user alienation but also to improve prevention efforts and reduce the potentially counter-intuitive effects of strictly prohibitive policies.

    Driving under the influence of drugs (DUID) is a worldwide problem with potentially major judiciary and life-threatening consequences. Up to now, only classical drugs of abuse (DOA) are tested for DUID detection. A challenging issue for drafting up-dated international drug policies is to take into account the recent and expanding new psychoactive substances (NPS) market. NPS consist in various narcotic or psychotropic drugs, most of them having a "legal" status, that replicate chemical structures and/or pharmacological effects of classical DOA. Although it is obvious that NPS can lead to impaired driving, the prevalence of NPS use in a DUID context is unknown since the applied roadside screening tests are not yet adapted for these compounds. Between January and December 2016, a total of 391 oral fluid specimens were obtained from used roadside immunochemical test devices for DOA (Drugwipe-5S ® device). These specimens were analyzed using liquid chromatography coupled with tandem mass spectrometry and high resolution mass spectrometry. NPS (mainly cathinone derivatives) were detected in 33 out of the 391 oral fluid samples. This NPS positivity rate of 8.4% in oral fluid of drivers who were submitted to a roadside drug testing in 2016 in France and in Belgium is comparable to the available blood data (NPS positivity rate of 7%) observed in 2015 in similar populations. Our results demonstrate the reality of driving after NPS use in French and Belgian drivers who were submitted to a roadside DOA test. As there is a lack of on-site detection methods to screen for NPS, the detection of NPS in a rapid and cost-effective DUID detection strategy is currently impossible. The expanding use of NPS, notably by drivers as reported here, and the inability of currently used drug detection tests, should be urgently addressed by road safety and law enforcement authorities.

  18. Understanding the development of a regulated market approach to new psychoactive substances (NPS) in New Zealand using Punctuated Equilibrium Theory.

    2018-05-09

    The short-lived regulated legal market for new psychoactive substances (NPS) in New Zealand marked a radical departure from the traditional prohibition-based approach to drugs. This paper aimed to enhance understanding of this policy change using Punctuated Equilibrium Theory (PET). The analysis draws on 3 years of evaluative research, including interviews with key stakeholders, analysis of legislation and policy documents and academic and grey literature. The reframing of the NPS issue from one of drug control to the need for stricter market regulation was achieved by the efforts of strategic policy entrepreneurs, including the legal high industry, drug law reform advocates, influential politicians and an independent legal advisory institution. This reframing was aided by the perceived saliency of the NPS problem and ineffectiveness of previous prohibition-based responses. In the absence of any political opposition to the regulatory approach, the Psychoactive Substances Act rapidly progressed through the Parliament. However, once the interim legal market was established, portrayal of the issues shifted away from experts and lobbyists to critique from local communities, local government, animal rights activists and the media, who viewed the new regime as a source of social and health problems. The mobilization of criticism ('Schattschneider mobilization') drew on ideas of animal welfare and community safety. With a looming national election, the government responded by ending the interim market with the urgent passage of amendment legislation. Punctuated Equilibrium Theory (PET) helps explain how New Zealand's Psychoactive Substances Act (PSA) policy first emerged on the political agenda and how the initial positive tone of expert support for reform shifted to a tide of popular criticism during the interim regime. However, with its emphasis on explaining agenda-setting, PET does not account for the legislative design shortcomings of the PSA. © 2018 Society for

    Full Text Available The Internet has played a major role in the distribution of New Psychoactive Substances (NPS, and crypto markets are increasingly used for the anonymous sale of drugs, including NPS. This study explores the availability of individual NPS and vendors on the crypto markets and considers whether crypto markets are a reliable platform for the sale of NPS. Data was collected from 22 crypto markets that were accessed through the hidden web using the Onion Router (Tor. Data collection took place bimonthly from October 2015 to October 2016 as part of the CASSANDRA (Computer Assisted Solutions for Studying the Availability aNd DistRibution of novel psychoActive substances project. In seven snapshots over 12 months, 808 unique vendors were found selling 256 unique NPS. The total number of individual NPS and vendors increased across the data collection period (increase of 93.6% and 71.6%, respectively. Only 24% (n = 61 of the total number of NPS and 4% (n = 31 of vendors appeared in every snapshot over the 12 months, whereas 21% (n = 54 of NPS and 45% (n = 365 of vendors only appeared once throughout the data collection. The individual NPS and vendors did not remain the same over the 12 months. However, the availability of NPS and vendors selling NPS grew. NPS consistently available on crypto markets could indicate popular substances.

    In France, recent data on the consumption of psychoactive substances (PASs) among women entering prison are virtually nonexistent. The objective of this study was to describe the characteristics of female entrants at Montluc prison in Lyon (France) and to estimate their PAS consumption. Between June 1, 2004 and December 31, 2008, of 841 women entering the Lyon correctional facility, 535 had an entrance interview, conducted by a nurse, during which a questionnaire was systematically proposed; 306 detainees did not have this interview and could not be included in the study because of an immediate transfer to another prison or emergency hospitalization. Socioeconomic and incarceration characteristics, PAS consumption, as well as consumption level (occasional, regular, abusive or dependence) and psychological distress of the 535 interviewed detainees were systematically noted. This psychological distress was defined by the presence in the entrant talks or behavior suggesting clinical symptoms such as anxiety, depression, delusion, delirium, and mood or behavior disorders. Descriptive analysis was undertaken with the Chi(2) test and Fisher's exact test for differences between the proportions observed. The average age of the 534 responding detainees was 31.5 years; 59.2% had had no ongoing professional activity in the 12 months prior to incarceration, and 21.6% had already been imprisoned before; 37.5% of the entrants reported dependence on tobacco and 13.7% on alcohol; 6.6% reported regular, abusive use or dependence on cannabis, 20.4% on psychotropic medications, and 7.7% on other drugs (heroin, cocaine, synthetic drugs) in the 6 months preceding their incarceration; 39.2% of the consumers at risk reported using at least two substances; 7.1% of detainees were on opioid substitution treatment. A multiple correspondence factor analysis was used to note specific characteristics of three groups of PAS consumers. More frequent among young women detainees, overall PAS

    The growth of novel psychoactive substances (NPS) over the last decade, both in terms of availability and consumption, is of increasing public health concern. Despite recent increases in related mortality, the circumstances surrounding and characteristics of individuals involved in NPS deaths at a population level remain relatively unknown. The Scottish National Drug Related Death Database (NDRDD) collects a wide-range of data relating to the nature and circumstances of individuals who have died a drug-related death (DRD). We conducted exploratory descriptive analysis of DRDs involving NPS recorded by the NDRDD in 2012. Statistical testing of differences between sub-groups was also conducted where appropriate. In 2012, we found 36 DRDs in Scotland to have NPS recorded within post-mortem toxicology. However, in only 23 of these cases were NPS deemed by the reporting pathologist to be implicated in the actual cause of death. The majority of NPS-implicated DRDs involved Benzodiazepine-type drugs (13), mainly Phenazepam (12). The remaining 10 NPS-implicated deaths featured a range of different Stimulant-type drugs. The majority of these NPS-implicated deaths involved males and consumption of more than one drug was recorded by toxicology in all except one case. NPS-implicated deaths involving Benzodiazepine-type NPS drugs appeared to involve older individuals known to be using drugs for a considerable period of time, many of whom had been in prison at some point in their lives. They also typically involved combinations of opioids and benzodiazepines; no stimulant drugs were co-implicated. Deaths where stimulant-type NPS drugs were implicated appeared to be a younger group in comparison, all consuming two or more Stimulant-type drugs in combination. This exploratory study provides an important insight into the circumstances surrounding and characteristics of individuals involved in NPS deaths at a population level. It identifies important issues for policy and practice

    Ever since the modern rediscovery of psychedelic substances by Western society, several authors have independently proposed that their effects bear a high resemblance to the dreams and dreamlike experiences occurring naturally during the sleep-wake cycle. Recent studies in humans have provided neurophysiological evidence supporting this hypothesis. However, a rigorous comparative analysis of the phenomenology (“what it feels like” to experience these states) is currently lacking. We investigated the semantic similarity between a large number of subjective reports of psychoactive substances and reports of high/low lucidity dreams, and found that the highest-ranking substance in terms of the similarity to high lucidity dreams was the serotonergic psychedelic lysergic acid diethylamide (LSD), whereas the highest-ranking in terms of the similarity to dreams of low lucidity were plants of the Datura genus, rich in deliriant tropane alkaloids. Conversely, sedatives, stimulants, antipsychotics, and antidepressants comprised most of the lowest-ranking substances. An analysis of the most frequent words in the subjective reports of dreams and hallucinogens revealed that terms associated with perception (“see,” “visual,” “face,” “reality,” “color”), emotion (“fear”), setting (“outside,” “inside,” “street,” “front,” “behind”) and relatives (“mom,” “dad,” “brother,” “parent,” “family”) were the most prevalent across both experiences. In summary, we applied novel quantitative analyses to a large volume of empirical data to confirm the hypothesis that, among all psychoactive substances, hallucinogen drugs elicit experiences with the highest semantic similarity to those of dreams. Our results and the associated methodological developments open the way to study the comparative phenomenology of different altered states of consciousness and its relationship with non-invasive measurements of brain physiology.

    Full Text Available New psychoactive substances (NPS are a heterogeneous and rapidly evolving class of molecules available on the global illicit drug market (e.g smart shops, internet, dark net as a substitute for controlled substances. The use of NPS, mainly consumed along with other drugs of abuse and/or alcohol, has resulted in a significantly growing number of mortality and emergency admissions for overdoses, as reported by several poison centers from all over the world. The fact that the number of NPS have more than doubled over the last 10 years, is a critical challenge to governments, the scientific community, and civil society (UNODC, World Drug Report, 2014; EMCDDA, European Drug Report 2014: Trends and developments. The chemical structure (phenethylamines, piperazine, cathinones, tryptamines, synthetic cannabinoids of NPS and their pharmacological and clinical effects (hallucinogenic, anesthetic, dissociative, depressant help classify them into different categories. In the recent past, 50% of newly identified NPS have been classified as synthetic cannabinoids followed by new phenethylamines (17%(WDR, 2014. Besides peripheral toxicological effects, many NPS seem to have addictive properties. Behavioral, neurochemical, and electrophysiological evidence can help in detecting them. This manuscript will review existing literature about the addictive and rewarding properties of the most popular NPS classes: cannabimimetics (JWH, HU, CP series and amphetamine-like stimulants (amphetamine, methamphetamine, methcathinone and MDMA analogues. Moreover, the review will include recent data from our lab which links JWH-018, a CB1 and CB2 agonist more potent than Δ9-THC, to other cannabinoids with known abuse potential, and to other classes of abused drugs that increase dopamine signaling in the Nucleus Accumbens (NAc shell.

    This study aimed to examine: 1) the relationship between being a runaway and the time since the first absconding event and adolescent substance use; 2) whether different kinds of psychoactive substances have a different temporal relationship to the first absconding event; and 3) whether the various reasons for the first absconding event are associated with different risks of substance use. Participants were drawn from the 2004-2006 nationwide outreach programs across 26 cities/towns in Taiwan. A total of 17,133 participants, age 12-18 years, who completed an anonymous questionnaire on their experience of running away and substances use and who were now living with their families, were included in the analysis. The lifetime risk of tobacco, alcohol, betel nut, and illegal drug/inhalant use increased steadily from adolescents who had experienced a trial runaway episode (one time lasting or= 2 times or lasting > 1 day), when compared to those who had never ran away. Adolescents who had their first running away experience > 6 months previously had a greater risk of betel nut or illegal drug/inhalant use over the past 6-months than those with a similar experience within the last 6 months. Both alcohol and tobacco use were most frequently initiated before the first running away, whereas both betel nut and illegal drug/inhalant use were most frequently initiated after this event. When adolescents who were fleeing an unsatisfactory home life were compared to those who ran away for excitement, the risk of alcohol use was similar but the former tended to have a higher risk of tobacco, betel nut, and illegal drug/inhalant use. More significant running away and a longer time since the first absconding experience were associated with more advanced substance involvement among adolescents now living in a family setting. Once adolescents had left home, they developed additional psychoactive substance problems, regardless of their reasons for running away. These findings have

    Full Text Available The aim of the present study was to investigate the university students’ views of possible situations and the reasons for the use of substances that can be addictive by their peers. So-called psychoactive substances (tobacco, alcohol, drugs, energy drinks can act as risk factors and  contribute to the development of a number of socially significant diseases.  The study did not provide for the study of the spread of harmful habits among young people, but only an analysis of the responses concerning the situation and the reasons for these phenomena.  The study involved 137 students aged 17 to 21 years.  It was found that the majority of respondents can not identify a single best reason, but pointed out a few of these reasons and situations.  It is shown that in the opinion of young people, the freer use of psychoactive substances among young people is primarily promoted by visits to discos, meeting with friends who are on the background of the lack of interesting activities and hobbies, as well as the situation, accompanied by an insufficient level of adult supervision, including the holidays period.  Analysis of the study results suggests a lack of skill level output from "uncomfortable" psychological situations among young people. The survey results indicate key influence of family and social environment on the degree of the risk-oriented behavior manifestation of young people.  Taking into account the significant contribution of risk factors in the state of public health indicators, analysis of the processes of formation and perception of health risks among young people requires special attention.  Conducting further systematic sociological studies, which will condition the direction and influence the quality of health preservation programs seems relevant and appropriate.

    The Internet has played a major role in the distribution of New Psychoactive Substances (NPS), and crypto markets are increasingly used for the anonymous sale of drugs, including NPS. This study explores the availability of individual NPS and vendors on the crypto markets and considers whether crypto markets are a reliable platform for the sale of NPS. Data was collected from 22 crypto markets that were accessed through the hidden web using the Onion Router (Tor). Data collection took place bimonthly from October 2015 to October 2016 as part of the CASSANDRA ( C omputer A ssisted S olutions for S tudying the A vailability a N d D ist R ibution of novel psycho A ctive substances) project. In seven snapshots over 12 months, 808 unique vendors were found selling 256 unique NPS. The total number of individual NPS and vendors increased across the data collection period (increase of 93.6% and 71.6%, respectively). Only 24% ( n = 61) of the total number of NPS and 4% ( n = 31) of vendors appeared in every snapshot over the 12 months, whereas 21% ( n = 54) of NPS and 45% ( n = 365) of vendors only appeared once throughout the data collection. The individual NPS and vendors did not remain the same over the 12 months. However, the availability of NPS and vendors selling NPS grew. NPS consistently available on crypto markets could indicate popular substances.

    Though illegal in the UK, in many countries novel psychoactive substances are quasi-legal synthetic compounds that are widely available online under the guise of research chemicals. These substances are relatively cheap and are often undetectable in standard drug screens. Nearly 200 such compounds are introduced yearly, and little is usually known about their metabolism or physiological effects. Consequently, managing patients in overdose situations on largely unknown substances usually involves supportive care, however anticipating and managing atypical side effects are challenging in the absence of knowledge of these compounds. In this report, we discuss our encounter with a 33-year-old unconscious man presenting with coingestion of a novel stimulant 3-fluorophenmetrazine with a rarely used benzodiazepine etizolam. This patient developed seizure-like activity and delayed widespread T-wave inversions, both of which ultimately resolved without sequelae. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    The world's status quo on recreational drugs has dramatically changed in recent years due to the rapid emergence of new psychoactive substances (NPS), represented by new narcotic or psychotropic drugs, in pure form or in preparation, which are not controlled by international conventions, but that may pose a public health threat comparable with that posed by substances listed in these conventions. These NPS, also known as 'legal highs' or 'smart drugs', are typically sold via Internet or 'smartshops' as legal alternatives to controlled substances, being announced as 'bath salts' and 'plant feeders' and is often sought after for consumption especially among young people. Although NPS have the biased reputation of being safe, the vast majority has hitherto not been tested and several fatal cases have been reported, namely for synthetic cathinones, with pathological patterns comparable with amphetamines. Additionally, the unprecedented speed of appearance and distribution of the NPS worldwide brings technical difficulties in the development of analytical procedures and risk assessment in real time. In this study, 27 products commercialized as 'plant feeders' were chemically characterized by gas chromatography-mass spectrometry and nuclear magnetic resonance spectroscopy. It was also evaluated, for the first time, the in vitro hepatotoxic effects of individual synthetic cathinones, namely methylone, pentedrone, 4-methylethcathinone (4-MEC) and 3,4-methylenedioxypyrovalerone (MDPV). Two commercial mixtures ('Bloom' and 'Blow') containing mainly cathinone derivatives were also tested, and 3,4-methylenedioxymethamphetamine (MDMA) was used as the reference drug. The study allowed the identification of 19 compounds, showing that synthetic cathinones are the main active compounds present in these products. Qualitative and quantitative variability was found in products sold with the same trade name in matching or different 'smartshops'. In the toxicity studies performed in

    The "opening" of the post-totalitarian societies of Eastern Europe increased the illegal spread of psychoactive substances (PAS) in the past decade. We studied psychoactive substance acute poisoning (PAS AP)--types of toxic agents involved, incidence rates, and their changes--as indirect indicators of the characteristics, magnitude and development of the problem in Bulgaria during the 1990-2000 period of socioeconomic transition and crisis after collapse of communism. The study analyzed retrospectively the caseload of all 571 PAS acute poisonings that occurred in the territory: 417 men (73%) and 154 women (27%); mean age 24.07y (range 10-75). The number of all AP and PAS AP showed a marked increase during the last 3years of the studied period, especially in 2000. The average PAS AP incidence rate for 1998-2000 (13.50/100,000) compared to the mean value for the preceding period 1990-1997 (5.76/100,000) showed a 2.34 fold increase. Acute alcohol intoxication was 62.7%, of all PASAP; the opioid 15.2% (heroin 11.0%, other opioids 4.2%); prescribed and over the counter drugs 12.6%; inhalants 1.1%; cannabis 1.1%; and cocaine 0.7%. Amphetamine (or amphetamine-like), hallucinogens and phencyclidine (or phencyclidine-like) AP were not encountered. The average percentage of alcohol AP for 1998-2000 compared to the preceding 1990-1997 dropped from 78.12% to 44.72% (1.75 fold), while that of opioids rose from 6.59% to 26.47% (4.02 fold), and that of the other drugs group from 12.22% to 21.78% (1.78 fold increase). The new non-alcoholic PAS AP (heroin, cocaine, inhalants and cannabis AP, as indirect indicators of narcotic exposure) showed a rapid increase. The data showed they are expanding and catching up with alcohol as a new cause of substance-related problems, thus becoming one of the important health and social problems of post-totalitarian society.

    The diffusion of novel psychoactive substances (NPSs), combined with the ability of the Internet to act as an online marketplace, has led to unprecedented challenges for governments, health agencies, and substance misuse services. Despite increasing research, there is a paucity of reliable information available to professionals working in the field. The paper will present the pilot results of the first mobile application (SMAIL) for rapid information sharing on NPSs among health professionals. The development of SMAIL was divided into 2 parts: (a) the creation of the application for registered users, enabling them to send an SMS or email with the name or "street name" of an NPS and receive within seconds emails or SMS with the information, when available and (b) the development of a database to support the incoming requests. One hundred twenty-two professionals based in 22 countries used the service over the pilot period of 16 months (from May 2012 to September 2013). Five hundred fifty-seven enquires were made. Users received rapid information on NPSs, and 61% of them rated the service as excellent. This is the right time to use mobile phone technologies for rapid information sharing and prevention activities on NPSs. Copyright © 2017 John Wiley & Sons, Ltd.

    2017-05-01

    Literature is quite poor about the clinical effects of novel psychoactive substances (NPS) and the long-term consequences of NPS use in psychiatric patients. Consequently, it is of the greatest interest to examine which effects NPS can exert in patients with previous severe mental illness (SMI), such as psychotic patients. The aim of this work was a comprehensive review about NPS use in patients with SMI. We searched Medline or PubMed for relevant English-language citations and reviews describing relationships between NPS use and mental disorders, as well as for the main groups of substances and associated psychiatric manifestations. All studies reporting single case or case series of patients were selected. The NPS use in patients with SMI is probably underestimated. The one existing systematic review considers only 14 studies, 12 of which are case reports. Most clinical results report acute symptom exacerbation of preexisting psychosis. Paranoid, mood, and aggression symptoms occur more frequently. NPS use could modify clinical features of SMI, but these conclusions cannot be generalizable. More evidence is needed to establish the causal and effective connection between NPS use and course of illness, type of psychiatric symptoms, and outcome of treatment in terms of adherence or response.

However prevalence and pattern of such dysfunctions are unknown in our environment. Aims To determine the prevalence of psychosocial dysfunction and depressive symptoms among adolescents who abuse substance and also note the influence of socio-demographic factors and type of substance on the pattern of dysfuction. Method A cross-sectional study was carried out among 900 adolescents selected from 29 secondary schools in Enugu metropolis. A multi-stage sampling procedure was used to select the students. The student drug use questionnaire was used to screen respondents for substance abuse. Those who were abusing substance and matched controls (non substance abusers were assessed for psychiatric symptoms using the 35-item Paediatric Symptom Checklist (PSC and the Zung Self-rating Depression Scale (SDS. Social classification was done using the parental educational attainment and occupation. Result A total of 290 students were current substance abusers. The substances most commonly abused were alcohol (31.6%, cola nitida (kola nut (20.7% and coffee (15.7%. Using the PSC scale, 70 (24.1% subjects compared to 29 (10.7% of the controls had scores in the morbidity range of ≥ 28 for psychosocial dysfuction.

    Objective To determine the association between consumption of psychoactive substances (PAS) and violent behavior in middle and high school students (grades 6 to 11) in the municipality of Itagui, Colombia. Method Cross-sectional study with a random sample of 646 middle and high school students. Participants volunteered to fill out the survey independently and consent was provided. Participants' identity was kept anonymous. The survey contained questions regarding socio-demographic characteristics, PAS consumption and violent behavior. For these variables a descriptive analysis was conducted. In addition, prevalence ratios and 95 % confidence intervals were calculated. Lastly, a multivariate analysis was performed to determine association and risk factors. Results 646 students satisfactorily answered the survey. The median age was 15 years [Rq 3]. From this sample, 45.6 % (295) were male and 54.3 % (351) were female; 59.3 % (383) had a low socio-economic status, 38.9 % (251) have a medium socio-economic status, and 0.8 % (5) have a high socio-economic status. Regarding PAS consumption, 53.4% (345) of the participants reported to have consumed at least one PAS; 46.9 % (162/345) reported to have consumed alcohol within the last year; 15.3 % (53/345) reported to have consumed marihuana. All consumed substances were found to be associated with and were identified as a risk factor for violent behavior. Conclusions SPA consumption is associated with youth violent behavior and represents a risk factor to perform such behavior. Substances such as heroin, cocaine, and ecstasy, represent greater risk when compared to other analyzed PAS. When the other variables were adjusted, cigarettes and inhalants consumption, among others, were no longer a risk factor.

Results, relevant to demographic and drug related items, are presented. Where meaningful, comparisons are made with previously published corresponding data obtained on male university students. Among the interesting findings are the following: Female students, compared with males, had better educated parents with jobs higher on social prestige hierarchy. But more boys than girls had personal sources of income and, relatively, big amounts of pocket money. Very few girls smoked cigarettes and used natural narcotics. Tranquilizers and hypnotics were taken by, almost, equal percentages of both sexes. But stimulants were consumed by more boys. Girls did not start experimentation with narcotics before the age of 16, whereas boys began such experimentation before reaching 12 years of age. Girls tried alcohol much more than they experimented with any other psychoactive substance. Among girls as well as boys we found a measurable trend for users to be more exposed than nonusers to what we call 'drug culture'. In the case of girls, close relatives have more weight than personal friends as sources of information about drugs. For boys, it is the opposite. Similarities as well as disparities were discussed and implications were emphasized.

    The proliferation of new psychoactive substances (NPS) in recent years has resulted in the development of numerous analytical methods for the detection and identification of known and unknown NPS derivatives. High-resolution mass spectrometry (HRMS) has been identified as the method of choice for broad screening of NPS in a wide range of analytical contexts because of its ability to measure accurate masses using data-independent acquisition (DIA) techniques. Additionally, it has shown promise for non-targeted screening strategies that have been developed in order to detect and identify novel analogues without the need for certified reference materials (CRMs) or comprehensive mass spectral libraries. This paper reviews the applications of HRMS for the analysis of NPS in forensic drug chemistry and analytical toxicology. It provides an overview of the sample preparation procedures in addition to data acquisition, instrumental analysis, and data processing techniques. Furthermore, it gives an overview of the current state of non-targeted screening strategies with discussion on future directions and perspectives of this technique.

    Abstract Introduction: Novel Psychoactive Substances (NPSs) are often sold online as "legal" and "safer" alternatives to International Controlled Drugs (ICDs) with captivating marketing strategies. Our aim was to review and summarize such strategies in terms of the appearance of the products, the brand names, and the latest trends in the illicit online marketplaces. Scientific data were searched in PsychInfo and Pubmed databases; results were integrated with an extensive monitoring of Internet (websites, online shops, chat rooms, fora, social networks) and media sources in nine languages (English, French, Farsi, Portuguese, Arabic, Russian, Spanish, and Chinese simplified/traditional) available from secure databases of the Global Public Health Intelligence Network. Evolving strategies for the online diffusion and the retail of NPSs have been identified, including discounts and periodic offers on chosen products. Advertisements and new brand names have been designed to attract customers, especially young people. An increased number of retailers have been recorded as well as new Web platforms and privacy systems. NPSs represent an unprecedented challenge in the field of public health with social, cultural, legal, and political implications. Web monitoring activities are essential for mapping the diffusion of NPSs and for supporting innovative Web-based prevention programmes.

    Several new psychoactive substances (NPS) have reached the illegal drug market in recent years, and ecstasy-like tablets are one of the forms affected by this change. Cathinones and tryptamines have increasingly been found in ecstasy-like seized samples as well as other amphetamine type stimulants. A presumptive method for identifying different drugs in seized ecstasy tablets (n=92) using ATR-FTIR (attenuated total reflectance - Fourier transform infrared spectroscopy) and PLS-DA (partial least squares discriminant analysis) was developed. A hierarchical strategy of sequential modeling was performed with PLS-DA. The main model discriminated four classes: 5-MeO-MIPT, methylenedioxyamphetamines (MDMA and MDA), methamphetamine, and cathinones. Two submodels were built to identify drugs present in MDs and cathinones classes. Models were validated through the estimate of figures of merit. The average reliability rate (RLR) of the main model was 96.8% and accordance (ACC) was 100%. For the submodels, RLR and ACC were 100%. The reliability of the models was corroborated through their spectral interpretation. Thus, spectral assignments were performed by associating informative vectors of each specific modeled class to the respective drugs. The developed method is simple, fast, and can be applied to the forensic laboratory routine, leading to objective results reports useful for forensic scientists and law enforcement.

    The study seeks to characterize the initiation and consumption pattern of psychoactive substances among adolescents and young adults enrolled in an Alcohol and Drug Psychosocial Care Center (CAPS-AD). This study was conducted with records of attendance and the consumption pattern was classified in accordance with WHO: infrequent use (lifetime use, per year or up to five days per month); frequent use (6 to 19 times in the past 30 days); heavy use (≥ 20 times in the last 30 days). In the age group comparison, the test for proportion and association analysis was used and the prevalence and prevalence ratio was calculated with a significance level of 5% and 95% confidence interval. Of the total of adolescents and young adults treated between 2003 and 2008 (475), most were male, single, poorly educated, live with relations and have psychic symptoms. Statistical significance was found for age at initiation of use: adolescents compared to young adults started earlier (≤ 14 years): tobacco, marijuana, cocaine, crack and other SPA consumption. Among adolescents, significant results were found for the less frequent consumption of tobacco, more frequent use of alcohol, and heavy consumption of marijuana. These findings may contribute to the preventive and therapeutic CAPS-AD programs.

    Full Text Available Abstract Background Novel psychoactive substances (NPS are new narcotic or psychotropic drugs that are not controlled by the United Nations drug convention that may pose a serious public health threat due to their wide availability for purchase on the internet and in so called “head shops.” Yet, the extent of their global use remains largely unknown. The aim of this study is to conduct a systematic review of the prevalence of NPS use in non-clinical populations. Methods This is a systematic review of observational studies. Embase, MEDLINE, PubMed, Cumulative Index to Nursing and Allied Health (CINAHL, Cochrane Library, Lilacs, Scopus, Global Health, PsychINFO, Web of Science, and the World Health Organization (WHO regional databases will be searched for eligible prevalence studies published between 2010 and 2016. Data from cross-sectional studies that report the prevalence of NPS use (one or more types in participants (of any age from censuses or probabilistic or convenience samples will be included. Data will be extracted from eligible publications, using a data extraction tool developed for this study. Visual and statistical approaches will be adopted instead of traditional meta-analytic approaches. Discussion This review will describe the distributions of various types of prevalence estimates of NPS use and explore the impact of different population groups and study-related and tempo-geographical variables on characteristics of these distributions over the period of 2010 to 2016.

    New psychoactive substances (NPS) are on offer worldwide online, in order to shed light on the purity and price of these substances in the European Union, a research collaboration was set up involving France, United Kingdom (UK), the Netherlands, Czech Republic and Poland. Per country, around 10 different NPS were test purchased from different webshops. Then, chemical analysis of NPS was done with according reference standards to identify and quantify the contents. In contrast to what is generally advertised on the webshops (>99%), purity varied considerably per test purchased NPS. Several NPS were mislabelled, some containing chemical analogues (e.g. 25B/C-NBOMe instead of 25I-NBOMe, pentedrone instead of 3,4-DMMC). But in some cases NPS differed substantially from what was advertised (e.g. pentedrone instead of AMT or 3-FMC instead of 5-MeO-DALT). Per gram, purity-adjusted prices of cathinones differed substantially between three countries of test purchase, with Poland being the least expensive. Synthetic cannabinoids were relatively the most expensive in the Czech Republic and least expensive in the UK. The current findings provides a snapshot of the price and chemical contents of NPS products purchased by different countries and in different webshops. There is a potential danger of mislabelling of NPS. The great variety in price and purity of the delivered products might be the result of the market dynamics of supply and demand and the role of law enforcement in different European countries.

    The establishment of a regulated legal market for new psychoactive substances (NPS, 'legal highs') under New Zealand's Psychoactive Substances Act (PSA) 2013 created a new commercial sector for psychoactive products, previously limited to alcohol and tobacco. To explore how the newly-recognised 'legal high' industry (LHI) viewed and responded to the changing regulatory and market environment. In-depth interviews with six key informants (KI) from the LHI: a leading entrepreneur, chemist, industry spokesperson, retailer, product buyer and a researcher commissioned by the LHI - were conducted, transcribed and analysed thematically. Formative work for the study included review of official LHI documents (websites, public submissions, self-regulation documents). The LHI stakeholders espoused an idealistic mission of shifting recreational users of alcohol, tobacco and illegal drugs towards "safer alternatives". Passage of the PSA was viewed as a success after years of lobbying led by pioneering LHI actors. The growth and professionalisation of the LHI resulted in an increasingly commercial market which challenged idealistic views of the original operators. LHI KI reported the targeting of young and low income customers, price cutting and increasing the strength of products as business strategies. Attempts by the LHI to self-regulate did not prevent escalation in the strength of products and fall in retail prices. The LHI reported outsourcing of manufacturing and exporting of their products to other countries, demonstrating an international business model. There was a tension between profit and idealistic motivations within the LHI and this increased as the sector became more commercialised. While the LHI distanced itself from both alcohol and tobacco, they reported the use of similar marketing, business and political lobbying strategies. Rules for engagement with new 'addictive consumption industries' are required to clarify the role they are permitted to play in the

    To describe the frequency of the use of alcohol and other drugs, as well as different types of victimization in men deprived of liberty in the prisons of Castile-La Mancha (Spain). A cross-sectional study was conducted in a sample of men deprived of liberty in four prisons in Castile-La Mancha. An anonymous questionnaire on victimization was distributed among a total of 425 prisoners, with a confidence interval of 95%. The most commonly reported assaults were verbal, affecting 41.4% of the prisoners (n=176) and the least common were sexual, affecting 7.8% (n=33). The most commonly consumed substance was cannabis, with 40.2% (n=171) of prisoners consuming it in the previous month. Victimization and substance use is a reality in prisons, and there is a statistically significant association between the two phenomena. This association should be further studied to design preventive measures and improve prison life. Copyright © 2014 SESPAS. Published by Elsevier Espana. All rights reserved.

    Evaluate substance use (tobacco, alcohol, psychotropic drugs, illicit drugs) declared before and during pregnancy. Two hundred and forty-five pregnant women were interviewed through a self-administered and anonymous questionnaire as they were going to a prenatal consultation in a maternity hospital in the Parisian area. Before pregnancy, 16.3% of women reported smoking and 10.2% carried on smoking during pregnancy. Altogether, 40.8% of women reported alcohol consumption before pregnancy; 25.3% of women had contact with alcohol during pregnancy; 4.5% reported tobacco and alcohol consumption during pregnancy. During the month preceding the study, the consumption of psychotropic drugs (hypnotics, antidepressants or sedatives) was reported by 3.7% of women and that of marijuana by 2.4%. Moreover, the marijuana consumers, who tend to drink alcohol more often, combine important social and familial difficulties and represent a high-risk group. Tobacco and alcohol use in this study were lower than in any previously conducted French surveys. Methodological specificities and cultural factors might explain those results. However, this is the first study that asses substance use and marijuana use, in particular, by French pregnant women.

    The purpose of this systematic review is to assess the effectiveness of brief interventions (BIs) as part of the Screening, Brief Intervention, and Referral to Treatment (SBIRT) model for reducing the nonmedical use of psychoactive substances. Bibliographic databases (including MEDLINE, Embase, The Cochrane Library, CINAHL, and PsycINFO to April 2012) and gray literature sources were searched. We included randomized controlled trials that opportunistically screened adolescents or adults and then provided a one-to-one, verbal BI to those at risk of substance-use harm. Of interest was the nonmedical use of psychoactive substances (for example, drugs prohibited by international law), excluding alcohol, nicotine, and caffeine. Interventions comprised four or fewer sessions and were compared with no/delayed intervention or provision of information only. Studies were assessed for bias using the Cochrane risk of bias tool. Results were synthesized narratively. Evidence was interpreted according to the GRADE framework. We identified 8,836 records. Of these, five studies met our inclusion criteria. Two studies compared BI with no BI, and three studies compared BI with information only. Studies varied in characteristics such as substances targeted, screening procedures, and BI administered. Outcomes were mostly reported by a single study, leading to limited or uncertain confidence in effect estimates. Insufficient evidence exists as to whether BIs, as part of SBIRT, are effective or ineffective for reducing the use of, or harms associated with nonmedical use of, psychoactive substances when these interventions are administered to nontreatment-seeking, screen-detected populations. Updating this review with emerging evidence will be important. CRD42012002414.

    The recent occurrence of deaths associated with the psychostimulant cis-4,4'-dimethylaminorex (4,4'-DMAR) in Europe indicated the presence of a newly emerged psychoactive substance on the market. Subsequently, the existence of 3,4-methylenedioxy-4-methylaminorex (MDMAR) has come to the authors' attention and this study describes the synthesis of cis- and trans-MDMAR followed by extensive characterization by chromatographic, spectroscopic, mass spectrometric platforms and crystal structure analysis. MDMAR obtained from an online vendor was subsequently identified as predominantly the cis-isomer (90%). Exposure of the cis-isomer to the mobile phase conditions (acetonitrile/water 1:1 with 0.1% formic acid) employed for high performance liquid chromatography analysis showed an artificially induced conversion to the trans-isomer, which was not observed when characterized by gas chromatography. Monoamine release activities of both MDMAR isomers were compared with the non-selective monoamine releasing agent (+)-3,4-methylenedioxymethamphetamine (MDMA) as a standard reference compound. For additional comparison, both cis- and trans-4,4'-DMAR, were assessed under identical conditions. cis-MDMAR, trans-MDMAR, cis-4,4'-DMAR and trans-4,4'-DMAR were more potent than MDMA in their ability to function as efficacious substrate-type releasers at the dopamine (DAT) and norepinephrine (NET) transporters in rat brain tissue. While cis-4,4'-DMAR, cis-MDMAR and trans-MDMAR were fully efficacious releasing agents at the serotonin transporter (SERT), trans-4,4'-DMAR acted as a fully efficacious uptake blocker. Currently, little information is available about the presence of MDMAR on the market but the high potency of ring-substituted methylaminorex analogues at all three monoamine transporters investigated here might be relevant when assessing the potential for serious side-effects after high dose exposure.

    Ecstasy (MDMA) in the US is commonly adulterated with other drugs, but research has not focused on purity of ecstasy since the phenomenon of "Molly" (ecstasy marketed as pure MDMA) arose in the US. We piloted a rapid electronic survey in 2015 to assess use of novel psychoactive substances (NPS) and other drugs among 679 nightclub/festival-attending young adults (age 18-25) in New York City. A quarter (26.1%) of the sample provided a hair sample to be analyzed for the presence of select synthetic cathinones ("bath salts") and some other NPS. Samples were analyzed using fully validated UHPLC-MS/MS methods. To examine consistency of self-report, analyses focused on the 48 participants with an analyzable hair sample who reported lifetime ecstasy/MDMA/Molly use. Half (50.0%) of the hair samples contained MDMA, 47.9% contained butylone, and 10.4% contained methylone. Of those who reported no lifetime use of "bath salts", stimulant NPS, or unknown pills or powders, about four out of ten (41.2%) tested positive for butylone, methylone, alpha-PVP, 5/6-APB, or 4-FA. Racial minorities were more likely to test positive for butylone or test positive for NPS after reporting no lifetime use. Frequent nightclub/festival attendance was the strongest predictor of testing positive for MDMA, butylone, or methylone. Results suggest that many ecstasy-using nightclub/festival attendees may be unintentionally using "bath salts" or other NPS. Prevention and harm reduction education is needed for this population and "drug checking" (e.g., pill testing) may be beneficial for those rejecting abstinence. Copyright © 2016 Elsevier Ireland Ltd.

    In Japan, fatalities among patients who experienced an acute reaction following self-administration of novel psychoactive substances (NPS) have been more frequently reported since June 2014. This survey aimed to document and analyze trends in NPS consumption in emergency patients. We conducted a multicenter retrospective survey of patients who were transported to emergency facilities after consuming NPS-containing products between January 2013 and December 2014. Letters requesting participation were sent to 467 emergency facilities, and questionnaires were mailed to facilities that agreed to participate. We surveyed 589 patients from 85 (18.2%) facilities. Most patients were male (89.6%) and young (median age, 30 years), and inhaled (88%) NPS contained in herbal products (80.5%). Harmful behavior was observed at the scene of acute reaction, including violence (6.9%), traffic accidents (4.9%), and self-injury or suicidal attempts (1.1%). Other than neuropsychiatric and physical symptoms, many patients also had physical complications such as rhabdomyolysis (17.5%), liver injury (12.4%), acute kidney injury (9%), and physical injury (1.9%). Of the 256 patients (43.5%) admitted to hospitals, 35 (5.9%) were hospitalized for seven or more days. Most patients (93.2%) completely recovered, although a few (1.4%) died. However, synthetic cannabinoids and synthetic cathinones were only detected in the blood of five patients. Consumption of NPS-containing products have been associated with harmful behaviors such as violence and traffic accidents, physical complications (e.g., rhabdomyolysis, liver injury), death, or physical and neuropsychiatric symptoms. Compared to a previous survey (2006-2012), the present survey revealed more severe toxicity.

    New psychoactive substances (NPSs) are rapidly spreading worldwide, and forensic laboratories are often requested to identify new substances for which no reference standards or analytical data are available. This article describes an analytical approach that was adopted in Italy by a few collaborative centres of the Italian Early Warning System for Drugs, which has contributed many alerts for the identification of different classes of NPSs in the last 24 months. Seized crystals and powders were initially analysed via single quadrupole gas chromatography/mass spectrometry (GC/MS), followed by liquid chromatography/high-resolution mass spectrometry (LC/HRMS) in the positive electrospray ionisation (ESI) mode at 100,000 full width at half maximum resolution (FWHM) without fragmentation to elucidate the elemental compositions of unknown molecules. Different fragmentation voltages during LC/HRMS were applied to study the accurate masses of the obtained characteristic fragments. Nuclear magnetic resonance (NMR) analyses were performed to identify specific isomers when necessary. Some interesting examples of unknown NPSs from seizures later identified in our laboratories are reported, with special focus on those cases where analytical standards were not available during analyses. These cases include cathinones, such as 3-methylmethcathinone (3-MMC), methylone, bk-MBDB (butylone), 4-methylethcathinone (4-MEC), flephedrone, methylenedioxypyrovalerone (MDPV) and pentedrone, methoxetamine, apinaca or AKB48, benzydamine, meta-chlorophenylpiperazine (m-CPP), 5-MeO-N,N-dialkyl tryptamines, such as 5-MeO-DALT and 5-MeOMIPT, benzofurans, such as 6-APB and 4-APB, and diphenidine (identified for the first time in Europe). The identification of NPSs in confiscated materials was successfully achieved via GC/MS coupled with LC/HRMS and, in a few cases, NMR analyses. The availability of GC/MS libraries is of great assistance in the identification of new drugs. Alternatively, the study

    The hidden Web is used for the anonymous sale of drugs, and with the UK Psychoactive Substances Act, 2016, implemented on May 26th 2016; it could increase as a platform for obtaining new psychoactive substances (NPS). This study aims to describe the NPS market on the visible and hidden Web preban, and assess whether the hidden Web is a likely place for the sale of NPS postban. Data collection of 113 online shops took place in October 2015. Data collection of 22 cryptomarkets took place every 2 months from October 2015 to 2016 as part of the CASSANDRA project. All online shops with a UK domain location sold NPS that were uncontrolled by the UK Misuse of Drugs Act, 1971, and closed after the ban. Of the cryptomarkets analysed, the total number of vendors selling NPS, number of substances, and listings advertised, all increased over the year. The majority of the NPS advertised on the hidden Web were phenethylamines and cathinones, yet the majority of uncontrolled NPS were synthetic cannabinoids. Vendors selling and availability of NPS increased over the 12 months of data collection. Potential displacement from the visible Web to hidden Web should be taken into consideration.

    In this communication, we present the first developed Molecularly Imprinted Polymers (MIPs) for the specific detection of a New Psychoactive Substance (NPS); namely, methoxphenidine (MXP) and its regioisomers. Selectivity of the MIP towards MXP is studied by analysing mixtures and an acquired street sample with High Performance Liquid Chromatography coupled to UV detection. The study demonstrates that the engineered polymers selectively extract MXP from heterogeneous samples, which makes for a very powerful diagnostic tool that can detect traces of MXP in complicated NPS samples.

    4,4'-Dimethylaminorex is a stimulant novel psychoactive substance (NPS) first detected in Europe in November 2012. It is a derivative of 4-methylaminorex, a substance controlled under Schedule 1 of the 1971 United Nations Convention on Psychotropic Substances. There is currently no information on the availability or cost of these substances from Internet suppliers. An Internet snapshot study was undertaken in English using established European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) methodology to determine the availability of 4-methylaminorex and 4,4'-dimethylaminorex in April 2014. Twenty Internet sites selling 4-methylaminorex were identified, 18 selling in US dollars and two in GB Pound Sterling. Fourteen (70 %) Internet sites had a minimum purchase amount of ≥10 g (compared to user doses of 10-25 mg). For the 18 suppliers selling in US$, 9 quoted a fixed price per gram irrespective of the amount ordered and 11 had a reducing price per gram with increasing purchase quantity (US$30.8 ± 34.2/g for 1 g purchase to US$15.2 ± 20.3/g for 1 kg purchase). Only one Internet site selling 4,4'-dimethylaminorex was identified, selling in Euros. The minimum purchase quantity was 500 mg. The price per gram reduced from 36.08/g for a 500 mg purchase to 2.20/g for a 100 g purchase. This Internet snapshot demonstrated that there was a greater availability from Internet suppliers of products advertised as 4-methylaminorex than 4,4'-dimethylaminorex, despite the 4-methylaminorex being an internationally controlled substance. Whilst this may reflect misunderstanding by suppliers, it has the potential to put those purchasing at risk of contravening border control and/or local law enforcement legislation. The use of methodology such as Internet snapshot surveys is of increasing interest to clinical/medical toxicologists in their understanding of the supply, availability and cost of novel psychoactive substances.

    As for substance-related disorders, there were several differences between ICD-10 and DSM-IV, however, the concept of "dependence" had been essential for both criteria. DSM-5 published in 2013 had erased dependence. This confuses us. It is important to recognize dependence again. "Abuse" is the self-intake behavior of drug against the social norms. Repeated abuse results in dependence. Dependence is a state of loss of control against drug use due to craving. Abuse can produce "acute intoxication", and repeated abuse under dependence can produce "chronic intoxication". It is important to understand abuse, dependence and "intoxication" based on their relationship from the point of time course.

    In prison, in 2012, according to various sources, from 4 to 56% of the European inmate population used psychoactive substances (PAS). The aim of our study was to describe PAS consumption during incarceration in the prison of Lyon-Corbas, France. A transversal descriptive study was conducted between September 23rd and September 27th 2013 among all inmates of this prison. We used an anonymous self-administered questionnaire, distributed at lunchtime and collected, the same day, at dinnertime, by the mental health service personnel. Among 785 inmates present at the time of the study in the prison of Lyon-Corbas, 710 were included and the response rate was 64.4% (95% CI [60.8-67.8]). Among 457 responding inmates, 16.4% (95% CI [13.2-20.0]) reported no PAS consumption. Among 382 consumers, 74.4% (95% CI [69.8-78.5]) used tobacco, 36.8% (95% CI [32.2-41.8]) cannabis, 30.4% (95% CI [25.9-35.1]) alcohol, 7.7% (95% CI [5.2-10.6]) heroin and 10.3% (95% CI [7.5-13.6]) cocaine. Furthermore, 15% of consumers had started PAS consumption during their incarceration. Among consumers of at least one PAS other than tobacco, cannabis and alcohol, the way of consumption was sniff for 60.0% (95% CI [48.5-70.2]) and injection for 31.0% (95% CI [21.6-42.1]). Use of several PAS at the same time and sharing sniffing and/or injection paraphernalia were other risky behaviors observed; 12% (95% CI [5.8-20.4]) of drug injectors declared using chlorine to sterilize their injection paraphernalia. Our study provides worrying data about PAS consumption in prison. The measures of prohibition do not prevent this consumption. There is even an initiation of consumption of PAS for 15% of the first-time incarcerated inmates. This finding should encourage public authorities to facilitate access of inmates to the care structures in prisons, to improve drug use prevention and care programs and to develop activities (sports, cultural, educational and vocational).

    In mid-July 2013, New Zealand passed the Psychoactive Substances Act (PSA), which allowed 'low risk' psychoactive products ('legal highs') to be approved for legal sale. In early May 2014, following public protest, the Psychoactive Substances Amendment Act (PSAA) was passed banning animal testing of psychoactive products, potentially making the new regime unworkable. To investigate strategies to overcome the impasse created by the animal testing ban. Solutions to the impasse were investigated using 'scenario' and 'stakeholder' analysis. Legislation, parliamentary debates, and regulatory statements related to the PSA and animal testing were reviewed. Strategies to resolve the impasse were discussed with stakeholders including the Psychoactive Substances Regulatory Authority (PSRA) officials, health officials, a legal high industry lawyer, and a leading legal highs manufacturer. This process generated six possible scenarios and five decision-making criteria of key importance to major stakeholders. Scenarios were then evaluated based on feedback from the industry and regulators. The six scenarios were: (1) pragmatic modification of the animal testing ban; (2) waiting until new non-animal test models are internationally accepted; (3) use of non-validated replacement test methods; (4) judicial challenge of the animal testing ban; (5) 'creative compliance' by only presenting human clinical trial results; and (6) philosophical re-conceptualisation of the 'benefits' from psychoactive products. Options 1 and 5 appear to be the most attractive overall solutions. However, both rely on a new political consensus and astute framing of the issues by political communicators. Political decision makers may be happy to accept Scenario 2 which would impose significant delays. A 'failed' pharmaceutical product with psychoactive effects may have the test data required to be approved under Scenarios 1 and 5. Ultimately, the pleasurable benefits from psychoactive products may need to be

    This article describes the perception of health risks in adolescents due to the consumption of cigarettes, alcohol and psychoactive substances in the Federation of Bosnia and Herzegovina (FBIH), as well as their observation of the behavior of their peers related to addictive behaviors. For the analysis was used a database from the European School Survey Project on Alcohol and Other Drugs (ESPAD) survey which was conducted in FBIH in 2011. The target population were students in the second grade of secondary schools in FBIH born in 1995 according to the ESPAD protocol. The total number of respondents from the cohort born in 1995 was 3813 students. The research results showed that the prevalence of risk perception due to the consumption of cigarettes, alcohol and psychoactive substances among adolescents in the FBIH is lower than the mean prevalence in countries which have implemented the ESPAD survey of 2011. PPreventive activities should be aimed at adolescent risk behaviours and empower them to make the right decisions that can have far reaching significance. Attention has to be paid to selective prevention that is directed towards individuals or subgroup of population where the risk of developing disorder is much higher than average.

    New psychoactive substances represent serious social and health problem as tens of new compounds are detected in Europe annually. They often show structural proximity or even isomerism, which complicates their analysis. Two methods based on ultra high performance supercritical fluid chromatography and ultra high performance liquid chromatography with mass spectrometric detection were validated and compared. A simple dilute-filter-and-shoot protocol utilizing propan-2-ol or methanol for supercritical fluid or liquid chromatography, respectively, was proposed to detect and quantify 15 cathinones and phenethylamines in human urine. Both methods offered fast separation (chromatography. Limits of detection in urine ranged from 0.01 to 2.3 ng/mL, except for cathinone (5 ng/mL) in supercritical fluid chromatography. Nevertheless, this technique distinguished all analytes including four pairs of isomers, while liquid chromatography was unable to resolve fluoromethcathinone regioisomers. Concerning matrix effects and recoveries, supercritical fluid chromatography produced more uniform results for different compounds and at different concentration levels. This work demonstrates the performance and reliability of supercritical fluid chromatography and corroborates its applicability as an alternative tool for analysis of new psychoactive substances in biological matrixes. © 2018 WILEY-VCH Verlag GmbH & Co.

    We explored emotional awareness in substance-dependent patients and its relationships to self-reported alexithymia. Sixty-four outpatients with drug dependence or alcohol dependence were evaluated before the beginning of treatment with the Hamilton Depressive Scale and the Covi Anxiety Scale, and they completed the Toronto Alexithymia Scale (TAS-20) and the Levels of Emotional Awareness Scale (LEAS). Subjects exhibited low levels of emotional awareness and TAS-20 scores were high. Both measures were not related to depressive and anxious symptomatology. This research is the first to provide LEAS results with substance-dependent patients and highlights their deficits in emotions' differentiation and complexity. The lack of a relationship between LEAS and TAS-20 is discussed from the methodological and theoretical points of view. (c) 2010 Wiley Periodicals, Inc.

    Over the last decade there has been greater use of novel psychoactive substances ('legal highs') across Europe and the United States, including increasing reports of use of diphenylprolinol (D2PM) and desoxypipradrol (2-DPMP). This review will discuss the pharmacology and mechanisms of action of these two compounds, available data on their sources and prevalence of use and reports of acute toxicity and fatalities associated with their use. PubMed was searched using the search terms 'D2PM', '2-DPMP', 'diphenyl-2-pyrrolidinyl-methanol', 'diphenylprolinol', '2-diphenylmethylpiperidine' and 'desoxypipradrol'. These searches identified 70 articles, only five of which were relevant. PHARMACOLOGY AND MECHANISMS OF ACTION: D2PM is a pyrrolidine analogue and 2-DPMP is a desoxy analogue of pipradrol. Animal studies have shown that 2-DPMP increases the release of dopamine and decreases dopamine re-uptake comparable to the effects of cocaine. The binding and activity of D2PM at the dopamine re-uptake transporter, based on currently published data, is also similar to cocaine, although it appears that D2PM has less biological activity. SOURCES AND PREVALENCE OF USE: D2PM and 2-DPMP is available from internet-based suppliers and street level drug dealers; there is currently no systematic data to be able to determine the relative importance of these routes of supply. There is no population level, and limited subpopulation level, data on the prevalence of use of D2PM/2-DPMP. In one 2011 study, 1.6% of 315 individuals in 'gay friendly' nightclubs in South London reported that they had used a pipradrol: 1.0% had used within the last year and 0.6% had used or were planning to use a pipradrol on the night of the survey. ACUTE TOXICITY: Reports on internet discussion fora describe prolonged euphoria and stimulant effects including euphoria, sweating and bruxism with use of D2PM and 2-DPMP. The first report of analytically confirmed acute D2PM toxicity described chest pain and

    A central task for the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) is to produce an annual report of the latest data available on drug demand and drug supply in Europe. This paper is intended to facilitate a better understanding of, and easier access to, the main quantitative European level data sets available in 2015. The European reporting system formally covers all 28 European Union (EU) Member States, Norway and Turkey and incorporates multiple indicators alongside an early warning system (EWS) on uncontrolled new psychoactive substances (NPS). While epidemiological information is based largely on registries, surveys and other routine data reported annually, the EWS collects case-based data on an ongoing basis. The 2015 reporting exercise is centred primarily on a set of standardized reporting tools. The most recent data provided by European countries are presented, including data on drug use, drug-related morbidity and mortality, treatment demand, drug markets and new psychoactive substances, with data tables provided and methodological information. A number of key results are highlighted for illustrative purposes. Drug prevalence estimates from national surveys since 2012 (last year prevalence of use among the 15-34 age band) range from 0.4% in Turkey to 22.1% in France for cannabis, from 0.2% in Greece and Romania to 4.2% in the United Kingdom for cocaine, from 0.1% in Italy and Turkey to 3% in the Czech Republic and the United Kingdom for ecstasy, and from 0.1% or less in Romania, Italy and Portugal to 2.5% in Estonia for amphetamine. Declining trends in new HIV detections among people who inject drugs are illustrated, in addition to presentation of a breakdown of NPS reported to the EU early warning system, which have risen exponentially from fewer than 20 a year between 2005 and 2008, to 101 reported in 2014. Structured information is now available on patterns and trends in drug consumption in Europe, which permits triangulation of

    The study represents an attempt at employing segmental hair analysis in complex poisonings with xenobiotic mixtures of heroine - cocaine - amphetamines in the context of the cause of death as a consequence of complex interaction mechanisms which occurred prior to death. Two cases of complex poisonings: heroine - cocaine and heroine - cocaine - amphetamines were analyzed and documented with macro- and microscopic examinations and complex toxicological examinations, including the analysis of classic biological material, i.e. samples of selective blood, and alternative material, i.e. hair samples. Determinations of opioids, cocaine and its metabolite and amphetamines in the hair biological matrix were performed using high performance liquid chromatography--atmospheric pressure chemical ionization--tandem mass spectrometry (HPLC-APCI-MS-MS). Segmental hair analysis of the investigated cases indicated a prolonged intake of similar psychoactive substances and a developed adaptation of the addicted to interaction mechanisms, which, however, led gradually to multiorgan anatomopathological changes, and in consequence to death.

    The field of new psychoactive substances (NPS) is highly dynamic and the situation changes from year to year. Therefore, the current review provides a timely update about the latest developments to help analysts keep the pace with NPS distribution. It covers PubMed-listed studies published between January 2014 and January 2016 dealing with the application of liquid chromatography (LC) coupled low- and high-resolution mass spectrometry (MS) for broad screenings for NPS in clinical (CT) and forensic (FT) toxicology. Latest developments and applications are highlighted and selected papers critically discussed. Comprehensive tables summarizing all discussed articles complete the overview. Finally, an outlook on the future of LC coupled MS in CT and FT is provided and readers will learn why low-resolution mass spectrometry might remain the standard for the next couple of years at least for easy-to-use quantitative screening procedures.

    This study describes and analyses the consumption of psychoactive substances in educational institutions, the school environment conditions and its relation to the school standing of the students. In the first stage, a quantitative evaluation was performed, based on the records of the Second National Survey of Secondary School Students carried out in Córdoba in 2005; the second stage used a qualitative approach. A multistage probabilistic sample of 4593 students was used for the quantitative assessment. The analysis comprised summary measurements, multivariate and factorial correspondence analysis, in all cases with a significance level of p consumption is lower among morning-shift students and that grade repetition and behavior problems are associated to consumption of illegal drugs. Furthermore, it was detected that students in night-shift schools with low academic and disciplinary demand standards have a higher probability of consumption. It is clear that as academic standards decrease, consumption increases.

    5-(2-aminopropyl)indole (5-IT) is a new psychoactive substance (NPS; "legal high" or "research chemical") structurally related to indoleamines and substituted phenethylamines and implicated in several fatalities. We describe the clinical characteristics and results of laboratory investigations of 14 analytically confirmed nonfatal cases of 5-IT intoxication within the Swedish STRIDA project. Observational case series of consecutive patients with admitted or suspected intake of NPS presenting to hospitals in Sweden in 2012. Blood and/or urine samples were collected from intoxicated patients presenting to emergency departments and intensive care units over the country. Analysis of NPS was performed using an LC-MS/MS multi-component method. Clinical data were collected when caregivers consulted the Poisons Information Centre and also retrieved from medical records. The severity of poisoning was graded retrospectively using the Poisoning Severity Score (PSS). Eleven male and three female patients (age: 21-53 years, median: 27) tested positive for 5-IT in 2012, all cases appearing in April-July. The 5-IT concentration in serum ranged between 0.015 and 0.59 μg/mL (median: 0.22; n = 8) and in urine between 0.005 and 24.7 μg/mL (median: 5.95; n = 12). Five intoxications were indicated to be caused by 5-IT alone, whereas additional psychoactive substances were detected in the other nine cases. Six (43%) of fourteen cases were graded as severe (PSS 3), five (36%) as moderate (PSS 2), and three (21%) as minor (PSS 1) poisonings. In the severe cases, agitation, hallucinations, dilated pupils without light reaction, tachycardia, hypertension, hyperthermia, myoclonus, muscle rigidity, arrhythmias, seizures, rhabdomyolysis, and/or renal failure were noted. The results demonstrated that severe clinical toxicity was commonly present in patients with analytically confirmed 5-IT exposure. The clinical features are consistent with a sympathomimetic toxidrome, and some patients also

    The recent emergence of new psychoactive compounds (novel psychoactive substances (NPS)) has raised prominent challenges in the fields of drug policy, substance use research, public health and service provision. The Recreational Drugs European Network project, funded by the European Commission, was implemented to improve the information stream to young people and professionals about effects/risks of NPS by identifying online products and disseminating relevant information through technological tools. Regular multilingual qualitative assessments of websites, drugs fora and other online resources were carried out using the Google search engine in eight languages from collaborating countries. These included the following: the UK, Norway, Belgium, Germany, Hungary, Poland, Italy and Spain. Products were tested and prevention messages were developed and disseminated via technological tools such as interactive websites, SMS alert, social networking (Facebook, Twitter), Multimedia (You Tube), Smartphone applications (iPhone) and virtual learning environments (Second Life). The Recreational Drugs European Network project established itself as the first Europe-wide prevention programme designed for NPS based on the efficacy of novel information and communication technology-based forms of intervention. More than 650 NPS products and combinations were identified; relevant information was disseminated to target population and advice was given to both European Union/international agencies and national policy makers. Web-monitoring activities are essential for mapping the diffusion of NPS and the use of technological tools can be successfully incorporated in specific prevention programmes. Furthermore, the involvement of multi-disciplinary international partnerships was and continues to be fundamental for responding to such a prominent challenge.

    2013-01-01

    The psychoactive effects of psychiatric medications have been obscured by the presumption that these medications have disease-specific actions. Exploiting the parallels with the psychoactive effects and uses of recreational substances helps to highlight the psychoactive properties of psychiatric medications and their impact on people with psychiatric problems. We discuss how psychoactive effects produced by different drugs prescribed in psychiatric practice might modify various disturbing and distressing symptoms, and we also consider the costs of these psychoactive effects on the mental well-being of the user. We examine the issue of dependence, and the need for support for people wishing to withdraw from psychiatric medication. We consider how the reality of psychoactive effects undermines the idea that psychiatric drugs work by targeting underlying disease processes, since psychoactive effects can themselves directly modify mental and behavioral symptoms and thus affect the results of placebo-controlled trials. These effects and their impact also raise questions about the validity and importance of modern diagnosis systems. Extensive research is needed to clarify the range of acute and longer-term mental, behavioral, and physical effects induced by psychiatric drugs, both during and after consumption and withdrawal, to enable users and prescribers to exploit their psychoactive effects judiciously in a safe and more informed manner.

    A range of information needs should be met in order to better understand and predict the longevity/existence of novel psychoactive substances (NPS). This conceptual paper argues that one way of assessing how long a molecule may be around is to document how the life cycles or natural histories of 'traditional' drugs and NPS evolve. The earliest indication of the possible appearance of a new substance might be evidenced on the DeepWeb. However, this means they are less visible, in line with the clandestine nature of drug use and supply. Therefore, monitoring discussion groups/fora needs the development of new methods compared to those used in the Surface Net. Issues needing consideration in establishing NPS life cycles are outlined here, together with the probable outcomes that could result. The approach advocated means that it should be easier to identify which NPS are likely to come up or are emerging in real time, and, therefore, pre-empt/prevent their supply.

    Misuse of codeine-containing medicines in combination with new psychoactive substances (NPS) is inadequately described. This study characterises codeine consumption amongst NPS users and non-NPS users to provide warning of health issues. Online survey conducted between July 2015 and March 2016. Out of 340 respondents, residing in a country in Europe and using codeine recently, 63.8% were female. Mean age: 34.9 years (SD = 12.4). Substance use included NPS (18.5%) and illicit controlled drugs (55.9%). Factors relating to codeine use found to significantly predict NPS use were consuming codeine extracted from combination tablets (OR = 16.79, 95% CI [8.67, 32.51]), obtaining codeine from friends, family, and acquaintances (OR = 3.98, 95% CI [1.82, 8.7]), use of illicit controlled drugs (OR = 34.99, 95% CI [8.39, 145.94]) and use of codeine to experience euphoria (OR = 6.41, 95% CI [3.42, 12.04]). Amongst NPS users, codeine is less likely to be used daily but more likely to be used for recreational purposes. Smaller populations engaging in high-risk use exist who take multiple drugs in high doses. Combinations of misused codeine and NPS highlight the need for policy to respond to a more complex drug situation. Copyright © 2017 John Wiley & Sons, Ltd.

    Full Text Available OBJECTIVE: To evaluate the association between the consumption of psychoactive substances (tobacco, alcohol and illicit drugs and demographic variables, mental health and family context among school-aged children. METHODS: The National Adolescent School-based Health Survey was held with a national sample of 109,104 students. Data regarding demographic variables, family background and mental health were collected. Logistic regression was used to evaluate the associations of interest. RESULTS: Multivariate analyses showed that alcohol consumption was higher among girls, drug experimentation was more frequent among boys and that there was no difference between sexes for smoking. Being younger and mulatto were negatively associated with the use of tobacco, alcohol and illicit drugs. Also negatively associated with such risk behaviors were characteristics of the family context represented by: living with parents, having meals together and parental supervision (when parents know what the child does in their free time. Moreover, characteristics of mental health such as loneliness and insomnia were positively associated with use of tobacco, alcohol and illicit drugs. Not having friends was positively associated with use of tobacco and illicit drugs and negatively associated with alcohol use. CONCLUSIONS: The study shows the protective effect of family supervision in the use of tobacco, alcohol and drugs and, on the contrary, the increasing use of substances according to aspects of mental health, such as loneliness, insomnia and the fact of not having friends. The study's findings may support actions from health and education professionals, as well as from the government and families in order to prevent the use of these substances by adolescents.

    To evaluate the association between the consumption of psychoactive substances (tobacco, alcohol and illicit drugs) and demographic variables, mental health and family context among school-aged children. The National Adolescent School-based Health Survey was held with a national sample of 109,104 students. Data regarding demographic variables, family background and mental health were collected. Logistic regression was used to evaluate the associations of interest. Multivariate analyses showed that alcohol consumption was higher among girls, drug experimentation was more frequent among boys and that there was no difference between sexes for smoking. Being younger and mulatto were negatively associated with the use of tobacco, alcohol and illicit drugs. Also negatively associated with such risk behaviors were characteristics of the family context represented by: living with parents, having meals together and parental supervision (when parents know what the child does in their free time). Moreover, characteristics of mental health such as loneliness and insomnia were positively associated with use of tobacco, alcohol and illicit drugs.

    Identification and quantification of new psychoactive substances (NPS), both in biological and non-biological samples, represent a hard challenge for forensic toxicologists. NPS are increasingly emerging on illegal drug market. Many cases of co-consumption of NPS and other substances have also been reported. Hence, the development of analytical methods aiming at the detection of a broad-spectrum of compounds (NPS and "traditional" drugs) could be helpful. In this paper, a fully validated screening method in blood for the simultaneous detection of 69 substances, including 64 NPS (28 synthetic cannabinoids, 19 synthetic cathinones, 5 phenethylamines, 3 indanes, 2 piperazines, 2 tryptamines, 2 phencyclidine, methoxetamine, ketamine and its metabolite) and 5 amphetamines (amphetamine, methamphetamine, MDMA, MDA, 3,4-methylenedioxy-N-ethylamphetamine - MDEA-) by a dynamic multiple reaction monitoring analysis through liquid chromatography - tandem mass spectrometry (LC-MS/MS) is described. This method is very fast, easy to perform and cheap as it only requires the deproteinization of 200μL of blood sample with acetonitrile. The chromatographic separation is achieved with a C18 column. The analysis is very sensitive, with limits of quantification ranging from 0.1 to 0.5ng/mL. The method is linear from 1 to 100ng/mL and the coefficient of determination (R(2)) was always above 0.9900. Precision and accuracy were acceptable at any quality control level and recovery efficiency range was 72-110%. Matrix effects did not negatively affect the analytical sensitivity. This method was successfully applied to three real cases, allowing identification and quantification of: mephedrone and methamphetamine (post-mortem); ketamine, MDMA and MDA (post-mortem); AB-FUBINACA (ante-mortem).

    Full Text Available Substance abuse and dependence among the employed have massive cost implications for South Africa. Employers are legally obliged to provide opportunities for the treatment of substance dependence before dismissal is considered. Problem areas are the following: inadequate identification of employees with substance-abuse problems, infrequent treatment referrals, and overlooking of substance abuse in the workplace. This article attempts to address these issues by providing an overview of literature dealing with the problem of substance abuse and dependence in the workplace. Addressing this problem calls for specialist intervention measures, which are discussed in the article.

    In recent years, new drugs, commonly known as new psychoactive substances (NPS), appeared on the market, which include, among others, synthetic cannabinoids, cathinones, and tryptamine analogs of psilocin. The aim of this work was to develop and validate a new method for simultaneous screening and quantification of 31 NPS in oral fluid by ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). The chosen target analytes represented different chemical and toxicological NPS classes, such as synthetic cathinones, piperazines, phenethylamines, synthetic cannabinoids, and their metabolites. The procedure involved a rapid sample preparation based on protein precipitation followed by clean-up utilizing microextraction by packed sorbent (MEPS); the quantitative analysis was performed by UHPLC-MS/MS. The MEPS clean-up, regardless of non-quantitative recoveries for some analytes, provided an effective removal of interfering compounds, as demonstrated by reduced matrix effects found at different concentrations for all the analytes. The validation protocol, based on SWGTOX guidelines, demonstrated the suitability of the proposed method for quantitative analysis: linearity range ranged over 3 or 4 orders of magnitude; precision and accuracy tests gave RSD% values below 25%, and accuracy ranged from 85.9% to 107%, accomplishing SWGTOX requirements. Limits of detection (LODs) ranged between 0.005 ng/mL and 0.850 ng/mL and limits of quantification (LOQs) from 0.015 to 2.600 ng/mL. Copyright © 2017 John Wiley & Sons, Ltd.

    Suicidal behavior is a major cause of injury and death worldwide, especially among adolescents and young adults. Few studies have tackled this issue in the Arab world. The present study investigated the prevalence and the risk factors of suicidal behaviors among Moroccan school students. From April 2012 to November 2013, a cross-sectional study was conducted in the North-Centre region of Morocco among students in public secondary schools selected using stratified cluster random sampling. The data were collected via anonymous self-administered questionnaires. The Mini International Neuropsychiatric Interview was used in its Moroccan Colloquial Arabic version to assess suicidality according to the DSM-IV criteria. A total of 3020 students (53 % boys) aged 11-23 years (average age = 16 ± 2.1 years) were included in the study. The prevalence of suicide ideation, suicide planning and suicide attempts during the last month were 15.7, 6.3, and 6.5 % respectively. Univariate analyses demonstrated that suicidal behaviors followed different epidemiological patterns. According to the multivariate analyses, the risk factors for all suicidal behaviors among Moroccan school students were the female gender, middle school level, urban locations, low family income, parents' divorce, tobacco consumption and psychoactive substances (alcohol and cannabis) use. The intervention of preventive programs has become an emergency to overcome the issue of suicidality in Morocco. Further researches on adolescents' suicidal behaviors are suggested to update temporal data and assess the effectiveness of potential interventions.

    Sewage-based epidemiology (SBE) employs the analysis of sewage to detect and quantify drug use within a community. While SBE has been applied repeatedly for the estimation of classical illicit drugs, only few studies investigated new psychoactive substances (NPS). These compounds mimic effects of illicit drugs by introducing slight modifications to chemical structures of controlled illicit drugs. We describe the optimization, validation, and application of an analytical method using liquid chromatography coupled to positive electrospray tandem mass spectrometry (LC-ESI-MS/MS) for the determination of seven NPS in sewage: methoxetamine (MXE), butylone, ethylone, methylone, methiopropamine (MPA), 4-methoxymethamphetamine (PMMA), and 4-methoxyamphetamine (PMA). Sample preparation was performed using solid-phase extraction (SPE) with Oasis MCX cartridges. The LC separation was done with a HILIC (150 x 3 mm, 5 µm) column which ensured good resolution of the analytes with a total run time of 19 min. The lower limit of quantification (LLOQ) was between 0.5 and 5 ng/L for all compounds. The method was validated by evaluating the following parameters: sensitivity, selectivity, linearity, accuracy, precision, recoveries and matrix effects. The method was applied on sewage samples collected from sewage treatment plants in Belgium and Switzerland in which all investigated compounds were detected, except MPA and PMA. Furthermore, a consistent presence of MXE has been observed in most of the sewage samples at levels higher than LLOQ. Copyright © 2015 John Wiley & Sons, Ltd.

    Using data from a large national representative survey on sexual behavior in France (Contexte de la Sexualité en France), this study analyzed the relationship between a multidimensional measure of sexual orientation and psychoactive substance use and depression. The survey was conducted in 2006 by telephone with a random sample of the continental French speaking population between the ages of 18 and 69 years. The sample used for this analysis consisted of the 4,400 men and 5,472 women who were sexually active. A sexual orientation measure was constructed by combining information on three dimensions of sexual orientation: attraction, sexual behavior, and self-definition. Five mutually exclusive groups were defined for men and women: those with only heterosexual behavior were divided in two groups whether or not they declared any same-sex attraction; those with any same-sex partners were divided into three categories derived from their self-definition (heterosexual, bisexual or homosexual). The consumption of alcohol and cannabis, which was higher in the non-exclusively heterosexual groups, was more closely associated with homosexual self-identification for women than for men. Self-defined bisexuals (both male and female) followed by gay men and lesbians had the highest risk of chronic or recent depression. Self-defined heterosexuals who had same-sex partners or attraction had levels of risk between exclusive heterosexuals and self-identified homosexuals and bisexuals. The use of a multidimensional measure of sexual orientation demonstrated variation in substance use and mental health between non-heterosexual subgroups defined in terms of behavior, attraction, and identity.

    The increasing number of new psychoactive substances (NPS) present in the illicit market render their identification in biological fluids/tissues of great concern for clinical and forensic toxicology. Analytical methods able to detect the huge number of substances that can be used are sought, considering also that many NPS are not detected by the standard immunoassays generally used for routine drug screening. The aim of this work was to develop a method for the screening of different classes of NPS (a total of 78 analytes including cathinones, synthetic cannabinoids, phenethylamines, piperazines, ketamine and analogues, benzofurans, tryptamines) from blood samples. The simultaneous extraction of analytes was performed by Dispersive Liquid/Liquid Microextraction DLLME, a very rapid, cheap and efficient extraction technique that employs microliters amounts of organic solvents. Analyses were performed by a target Ultrahigh Performance Liquid Chromatography tandem Mass Spectrometry (UHPLC-MS/MS) method in multiple reaction monitoring (MRM). The method allowed the detection of the studied analytes with limits of detection (LODs) ranging from 0.2 to 2ng/mL. The proposed DLLME method can be used as an alternative to classical liquid/liquid or solid-phase extraction techniques due to its rapidity, necessity to use only microliters amounts of organic solvents, cheapness, and to its ability to extract simultaneously a huge number of analytes also from different chemical classes. The method was then applied to 60 authentic real samples from forensic cases, demonstrating its suitability for the screening of a wide number of NPS. Copyright © 2015 Elsevier B.V.

    We have introduced cognitive behavior therapy (CBT) into the treatment of substance dependence patients, which involves disease education and focused group therapy to obtain insight into the taking behavior and to establish concrete countermeasures to prevent relapse. We have created a bio-cognitive model based on biological aspects to explain the pathology of substance dependence. 'Dependence' is a term in behavioral pharmacology defined as reinforced drug seeking and taking behavior. Changes in taking behavior are thought to occur due to the repetition of the reinforcement action of psychoactive substances in the reward system of the brain. Therefore, when intake desire is strong, it is hard for patients to control themselves, and there is a feature of difficulties considering the process of thinking in CBT. In other words, when craving becomes strong, a chain of behavior happens spontaneously, without schema, involving automatic thoughts. We think that the improvement of protracted withdrawal syndrome (PWS) and entire frontal lobe function are important in learning to discern distortion of cognition. When PWS is improved, a conflict is easy to bring about in the process of drug seeking and taking behavior. And, it is easy to execute avoidance plans (coping skills) which are established to cope with craving in advance. We think that a goal for treatment is to discern drug seeking and taking behavior with natural emotion. The recovery of PWS and frontal lobe dysfunction takes a long time with a serious dependence, so we must perform repetition of CBT. As the treatment introduction of involuntary admission cases is adequate or cases of 1 to 3 months of admission treatment based on voluntary admission are hard to treat, treatment to obtain insights into patients while carrying out repeated CBT using a bio-cognitive model and to improve PWS could be a possibility as one treatment for the pathology of diversified substance dependence.

    Sewage profiling as a mean to estimate consumption of drugs of abuse is gaining increasing attention. However, only scarce data are available so far on the impact of microbial biotransformation on the presence and hence detectability of drugs of abuse and their metabolites in wastewater (WW) samples. The aim of this work was therefore to study the biotransformation pathways of the novel psychoactive substance 3,4-methylenedioxypyrovalerone (MPDV) in WW by incubating it, based on the OECD guideline 314 A. MDPV was incubated (100 μg/L) for 10d at 22 °C in WW from a local WW treatment plant. Furthermore, urine and feces collected from rats administered 20mg MDPV/kg BW were incubated correspondingly. Samples were worked-up either by centrifugation/filtration and solid-phase (HCX) extraction or QuEChERS. High resolution (HR) mass spectra (MS) were recorded using an Orbitrap mass spectrometer. All products were identified via their HR-MS(2) spectra and chromatographic properties. The observed biotransformations in WW were: demethylenation and subsequent O-methylation, hydroxylation at the phenyl part, hydroxylation at the pyrrolidine part with subsequent methylation or oxidation, N-demethylation, and hydroxylation at the alkyl part as well as combination of them. In total, 12 biotransformation products were identified after 10 days of incubation. Three of these biotransformation products were previously reported to be also rat and human metabolites. No additional MDPV biotransformation products could be found after incubating the rat urine and feces samples. Instead, the urinary phase II glucuronides were nearly completely cleaved after one day of WW incubation. The presented study indicates that demethylenyl-methyl MDPV, the most abundant metabolite in human urine, should be the best indicator in WW to estimate its use. Copyright © 2014 Elsevier B.V.

  13. 5-(2-Aminopropyl)indole (5-IT): a psychoactive substance used for recreational purposes is an inhibitor of human monoamine oxidase (MAO).

    Herraiz, Tomás; Brandt, Simon D

    2014-01-01

    5-(2-Aminopropyl)indole (5-IT) is a psychoactive compound that has recently been associated with several fatal and non-fatal intoxications in a number of European countries. There are indications that acute effects may include symptoms of monoaminergic (e.g. serotonin) toxicity and one mechanism involved in the increase of serotonin levels includes the inhibition of monoamine oxidase. This study investigated the effect of 5-IT on human MAO-A and -B isozymes using kynuramine as the substrate. Substrate conversion to 4-hydroxyquinoline was monitored by high-performance liquid chromatography coupled to diode array detection. This method was employed to determine the extent of MAO inhibition (IC50 and Ki ) and it was found that 5-IT was a selective, competitive and reversible inhibitor of MAO-A. 5-IT revealed a relatively potent ability to inhibit MAO-A (IC50  =1.6 μM and Ki  =0.25 μM) while MAO-B inhibition was not observed (0-500 μM 5-IT). Under identical experimental conditions, other established inhibitors of MAO-A and antidepressants provided the following IC50 values: clorgyline 16 nM, harmaline 20 nM, toloxatone 6.7 μM and moclobemide >500 μM. These data indicated that 5-IT was less potent than clorgyline and harmaline but more potent than toloxatone and moclobemide under the in-vitro conditions studied. The inhibition of MAO-A suggests that 5-IT by itself or in combination with other substances may be able to potentiate serotonergic/monoaminergic effects and further studies are needed to clarify its relevance to the adverse effects reported for 5-IT.

    There has been increasing interest in the availability of non-prescription benzodiazepines and their sale as new psychoactive substances. We wanted to determine UK availability from Internet suppliers and motivations for use of three benzodiazepines (diclazepam, flubromazepam, and pyrazolam). In November 2014 and March 2016, using the European Monitoring Centre for Drugs and Drug Addiction Snapshot Methodology, Internet search engines ( google.co.uk , uk. yahoo.com and ask.com.uk ) were searched using the terms 'buy diclazepam', 'buy flubromazepam' and 'buy pyrazolam'. Threads from drug-user forums ( bluelight.org , drugs-forum.com , erowid.org , legalhighsforum.com ) were analysed using a general inductive approach. Data were converted into price per gram/pellet to allow cost comparisons and to determine motivations for use. There was an increase in websites selling these benzodiazepines between 2014 and 2016: diclazepam (49 in 2014 to 55 in 2016), pyrazolam (33 to 35), and flubromazepam (39 to 45). Thirty-eight (63.3%) sites were based in the UK/Europe. Drugs were sold as pellets (49 websites, 81.7%), powder (19, 31.7%), and blotters (1, 1.7%). Pill forms were not available, and one (1.7%) website sold diclazepam/flubromazepam in liquid form. The cost reduced with increasing purchase quantities. Main motivations for use included anxiolysis, management of benzodiazepine withdrawal, sedation/sleep aid, and management of stimulant withdrawal. These three benzodiazepines are widely available online, most commonly as pellets, and are (mis)used for a number of reasons. This study could be used to support triangulation of data from other sources to inform harm minimisation strategies.

  15. Detection of “Bath Salts” and Other Novel Psychoactive Substances in Hair Samples of Ecstasy/MDMA/“Molly” Users

    Background Ecstasy (MDMA) in the US is commonly adulterated with other drugs, but research has not focused on purity of ecstasy since the phenomenon of “Molly” (ecstasy marketed as pure MDMA) arose in the US. Methods We piloted a rapid electronic survey in 2015 to assess use of novel psychoactive substances (NPS) and other drugs among 679 nightclub/festival-attending young adults (age 18–25) in New York City. A quarter (26.1%) of the sample provided a hair sample to be analyzed for the presence of select synthetic cathinones (“bath salts”) and some other NPS. Samples were analyzed using fully validated UHPLC-MS/MS methods. To examine consistency of self-report, analyses focused on the 48 participants with an analyzable hair sample who reported lifetime ecstasy/MDMA/Molly use. Results Half (50.0%) of the hair samples contained MDMA, 47.9% contained butylone, and 10.4% contained methylone. Of those who reported no lifetime use of “bath salts”, stimulant NPS, or unknown pills or powders, about four out of ten (41.2%) tested positive for butylone, methylone, alpha-PVP, 5/6-APB, or 4-FA. Racial minorities were more likely to test positive for butylone or test positive for NPS after reporting no lifetime use. Frequent nightclub/festival attendance was the strongest predictor of testing positive for MDMA, butylone, or methylone. Discussion Results suggest that many ecstasy-using nightclub/festival attendees may be unintentionally using “bath salts” or other NPS. Prevention and harm reduction education is needed for this population and “drug checking” (e.g., pill testing) may be beneficial for those rejecting abstinence. PMID:26883685

    In recent years, there has been an increase in emergence and use of novel psychoactive substances (NPS) in the US and worldwide. However, there is little published epidemiological survey data estimating the prevalence of use in the US. Data on self-reported NPS use came from the National Survey of Drug Use and Health (2009-2013), a national representative sample of non-institutionalized individuals in the US. Subjects were asked to provide names of (non-traditional) drugs they used that they were not specifically asked about. We examined lifetime prevalence and sociodemographic correlates of self-reported use of new and uncommon synthetic drugs (NPS) among subjects ages 12-34-years-old. 1.2% of subjects self-reported any use of the 57 NPS we examined. Use of psychedelic tryptamines (primarily DMT) was most common, followed by psychedelic phenethylamines (e.g., 2C series) and synthetic cannabinoids. Prevalence of self-reported use of NPS increased from 2009 to 2013 and use was most common among males, whites, older subjects, those of lower income, and among those residing in cities. Lifetime use of various other illicit drugs (e.g., LSD, cocaine, ecstasy/MDMA) was highly prevalent among NPS users. This the first study reporting on use of a variety of NPS in a nationally representative US sample; however, use appears to be underreported as other national data suggest higher rates of NPS (e.g., synthetic cannabinoid) use. Developing more adaptable survey tools and systematically assessing NPS use would allow researchers to ask about hundreds of NPS and improve reporting as new drugs continue to rapidly emerge.

    There is limited published scientific data on vaping recreational drugs other than cannabis. A recent review suggested that 15% of people vaping cannabis have also vaped a synthetic cannabinoid receptor agonist (SCRA) and identified over 300 Internet reports of e-liquid manufacture of recreational drugs and/or new psychoactive substances (NPS). To determine the prevalence of use of electronic vaping devices for recreational drug and NPS delivery in the UK. A voluntary online survey using a convenience sample of UK adult participants (aged 16 years old and over) identified by a market research company. Data was collected regarding demographics, smoking history, electronic vaping device history and recreational drug/NPS use and route of administration. There were 2501 respondents. The mean (±SD) age was 46.2 ± 16.8 years old. The commonest lifetime recreational drug used was Cannabis (818, 32.7%). The majority of respondents had smoked (1545, 61.8%) with 731 (29.2%) being current smokers. The most commonly used SCRA product was 'Spice Gold' (173, 6.9%) and SCRA compound was ADB-CHMICA (48, 1.9%). 861 (34.4%) had used an electronic vaping device; 340 (13.6%) having used them for recreational drug administration; 236 (9.4%) reporting current use. The commonest lifetime recreational drug to be vaped was cannabis (155, 65.7%), with electronic cigarettes (230, 48.2%) being the commonest reported route of SCRA compound administration. 9.4% of respondents currently use electronic vaping devices for recreational drug administration with 6.2% reporting lifetime cannabis vaping use. Further larger scale studies are required to help inform the appropriate treatment and primary prevention strategies. © The Author 2017.

    turn to substances with the objective of being able to stay up more hours with a sharp attention focused on their study. However, these substances can interfere long term memory and can generate pharmaceutical dependency. Aim. To establish the prevalence of the use of psychoactive substances in University students and to relate it with sleeping patterns and social-economic-educational characteristics. Subjects and methods. Cross-sectional study using standardized questionnaire with multiple choice system administered to 122 Anatomy students in the year 2009. Statistic parameters were applied and an informed consent was demanded. Results. 79.51% said that they were not able to read all the topics and 36.89% said that they memorized concepts; 25% started to memorize subjects three days before the exam, 20.49% did it the previous day, and 19.67% memorized subjects the night before the exam without sleeping. 25.41% answered that they used substances for sleeping and 41.8% used some substances to increase studying hours, such as: coffee, energy drinks, psychopharmacological medication (45.09% modafinil and methylphenidate and acetylsalicylic acid. The numbers of hours working correlated with the number of substances consumed (r = 0.89; students that where taking the subject again had less hours of sleep indirectly correlated with the use of psychoactives (r = -0.86. Conclusions. We recorded a high prevalence of consumptions of psychoactive substances, especially amongst students that are repeating the course and students that had jobs. It is of utmost importance to implement pedagogical tools that increase motivation, attention, and the associative capacities under an integrative-educational conception.

    The global increase in the production and abuse of cathinone-derived New Psychoactive Substances (NPSs) has developed the requirement for rapid, selective and sensitive protocols for their separation and detection. Electrochemical sensing of these compounds has been demonstrated to be an effective method for the in-field detection of these substances, either in their pure form or in the presence of common adulterants, however, the technique is limited in its ability to discriminate between structurally related cathinone-derivatives (for example: (±)-4′-methylmethcathinone (4-MMC, 2a) and (±)-4′-methyl-N-ethylmethcathinone (4-MEC, 2b) when they are both present in a mixture. In this paper we demonstrate, for the first time, the combination of HPLC-UV with amperometric detection (HPLC-AD) for the qualitative and quantitative analysis of 4-MMC and 4-MEC using either a commercially available impinging jet (LC-FC-A) or custom-made iCell channel (LC-FC-B) flow-cell system incorporating embedded graphite screen-printed macroelectrodes. The protocol offers a cost-effective, reproducible and reliable sensor platform for the simultaneous HPLC-UV and amperometric detection of the target analytes. The two systems have similar limits of detection, in terms of amperometric detection [LC-FC-A: 14.66 μg mL(-1) (2a) and 9.35 μg mL(-1) (2b); LC-FC-B: 57.92 μg mL(-1) (2a) and 26.91 μg mL(-1) (2b)], to the previously reported oxidative electrochemical protocol [39.8 μg mL(-1) (2a) and 84.2 μg mL(-1) (2b)], for two synthetic cathinones, prevalent on the recreational drugs market. Though not as sensitive as standard HPLC-UV detection, both flow cells show a good agreement, between the quantitative electroanalytical data, thereby making them suitable for the detection and quantification of 4-MMC and 4-MEC, either in their pure form or within complex mixtures. Additionally, the simultaneous HPLC-UV and amperometric detection protocol detailed herein shows a marked improvement

    Aims To assess past-year prevalence rates of substance use behaviors and substance dependence across three major dimensions of sexual orientation (identity, attraction, and behavior) in a large national sample of adult women and men in the United States. Design Data were collected from structured diagnostic face-to-face interviews using the Alcohol Use Disorder and Associated Disabilities Interview Schedule DSM-IV Version (AUDADIS-IV). Setting Prevalence estimates were based on data collected from the 2004–2005 (Wave 2) National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Participants A large national sample of 34,653 adults aged 20 years and older: 52% female, 71% White, 12% Hispanic, 11% African American, 4% Asian, and 2% Native American or other racial/ethnic categories. Findings Approximately 2% of the sample self-identified as lesbian, gay or bisexual; 4% reported at least one lifetime same-sex sexual partner, and 6% reported same-sex sexual attraction. Although non-heterosexual orientation was generally associated with a higher risk of substance use and substance dependence, the majority of sexual minority respondents did not report substance use or meet criteria for DSM-IV substance dependence. There was considerable variation in substance use outcomes across sexual orientation dimensions; these variations were more pronounced among women than among men. Conclusions Results support previous research findings of heightened risk of substance use and substance dependence among some sexual minority groups and point to the need for research that examines reasons for such differences. Results also highlight important gender differences and question previous findings indicating uniformly higher risk for substance dependence among sexual minorities. Risks appear to vary based on gender and how sexual orientation is defined. Findings have implications for prevention and intervention efforts that more effectively target subgroups at greatest

    Several factors influence the beginning and maintenance of substance use. The purpose of this study was to examine as well as to compare 'self-regulation' in both substance dependent and non-substance dependent individuals. In a cross-sectional study 228 (118 substance dependent and 110 with no history of using substance) participants aged 16-55 were recruited. All of the participants were asked to complete the Self-Regulation Inventory (SRI-25) and a demographic characteristics data checklist. Data was analyzed using descriptive statistics (frequency, mean and standard deviation) and the t-test. The results showed significant differences between substance dependent and non- substance dependent groups in all the scales of the self-regulation inventory including positive actions, controllability, expression of feelings and needs, assertiveness, and well-being seeking (p<0.01). Self-regulation and self-control skills in drug dependent individuals are lower than those without substance dependence individuals. It is concluded that substance use may related to a deficiency in self-control and regulation of feelings. Therefore, for prevention and treatment of substance dependence disorder, it is necessary to work out and exploit strategies that include the improvement of self-regulation.

    Although bipolar disorder is the Axis I psychiatric disorder associated with the highest rate of co-occurring substance use disorders, little research has focused on treatments specifically designed for these patients. The author and his colleagues have developed and studied Integrated Group Therapy (IGT) for this population. This paper describes common themes that have emerged in carrying out IGT for patients with bipolar disorder and substance dependence. These include the strong emphasis on depression, as opposed to mania; the predominance of hopelessness; specific patterns of medication noncompliance; and the implications of patients' labeling their substance use as self-medication. Therapeutic aspects involved in addressing these themes are discussed.

The prevailing view in the literature is that mothers of drug-dependent patients can be characterized by strong emotional bonds and overprotection. Studies suggest that maternal rejection could be a major risk factor of developing drug addiction. This work is a continuation of our previous study of childhood parenting experiences of substance-dependent patients. The aims were to compare the personality profile of mothers of substance-dependent patients and that of mothers of matched control subjects; and to examine the relation between the personality of mothers of addicts, and severity of their offspring’s addiction. The study group consisted of 20 mothers of substance-dependent patients and a control group of 35 mothers of non-dependent subjects; mothers of both groups were age matched. Patients were diagnosed according to DSM IV criteria. Personalities of mothers of both groups were assessed using the Minnesota Multiphasic Personality Inventory (MMPI. Substance-dependent patients (sons were administered the Addiction Severity Index (ASI. The mean scores of the MMPI Scales were higher for mothers of dependent patients compared to mothers of non-dependent subjects.

    To determine whether the following symptoms: depressive symptoms, eating disorder symptoms and obsessive-compulsive symptoms among adolescents in Kraków secondary schools are associated with an increased risk of psychoactive substance use. A representative sample of the population of Kraków secondary school pupils was tested. A two-stage draw method identified a group of 2034 2nd form pupils of all types of secondary schools: grammar schools, technical schools and vocational schools (17-year olds). They were tested using the following screening questionnaires: Beck Depression Scale, EAT-26 eating disorders scale, Obsessive-compulsive disorder (Leyton) scale and the author's drug questionnaire. The incidence of depressive symptoms among boys and girls is associated with an increased risk of alcohol use (74.8% among depressive boys versus 65.8% in the depressive group of girls), cigarette smoking (42.7% vs. 46.7%) and drug use (29.0% vs. 18.6%). All of the relationships are statistically significant in both sexes. 41.7% depressive boys admit to smoking, vs. only 32.6% in the non-depressive group. In the girls' group, these relationships are as follows: 46.7% versus 32.1%. The relationships are statistically significant in both sexes. The incidence of eating disorder symptoms among boys and girls is associated with a higher risk of alcohol use (respectively: 73.5% vs. 61.9%), cigarette smoking (42.1% vs. 46.9%), and drug use (31.6% versus 21.5%). Compared with a group of young people without eating disorder symptoms, the relationships are of statistical significance. Comorbidity of the following symptoms was found: depressive symptoms, eating disorder symptoms, obsessive-compulsive symptoms and symptoms of psychoactive substance use. The presence of depressive symptoms increases the risk of the use of psychoactive substances, especially alcohol and tobacco, to a lesser extent--drugs, both in the boys and in the girls.

    This review summarizes the history of the development of diagnostic constructs that apply to repetitive substance use, and compares and contrasts the nature, psychometric performance and utility of the major diagnoses in the Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD) diagnostic systems. The available literature was reviewed with a particular focus on diagnostic concepts that are relevant for clinical and epidemiological practice, and so that research questions could be generated that might inform the development of the next generation of DSM and ICD diagnoses. The substance dependence syndrome is a psychometrically robust and clinically useful construct, which applies to a range of psychoactive substances. The differences between the DSM fourth edition (DSM-IV) and the ICD tenth edition (ICD-10) versions are minimal and could be resolved. DSM-IV substance abuse performs moderately well but, being defined essentially by social criteria, may be culture-dependent. ICD-10 harmful substance use performs poorly as a diagnostic entity. There are good prospects for resolving many of the differences between the DSM and ICD systems. A new non-dependence diagnosis is required. There would also be advantages in a subthreshold diagnosis of hazardous or risky substance use being incorporated into the two systems. Biomedical research can be drawn upon to define a psychophysiological 'driving force' which could underpin a broad spectrum of substance use disorders.

    Although caffeine is the most commonly used psychoactive substance and often produces symptoms of toxicity and dependence, little is known, especially in community samples, about the association between caffeine use, toxicity and dependence and risk for common psychiatric and substance use disorders. Assessments of lifetime maximal caffeine use and symptoms of caffeine toxicity and dependence were available on over 3600 adult twins ascertained from the population-based Virginia Twin Registry. Lifetime histories of major depression (MD), generalized anxiety disorder (GAD) and panic disorder, alcohol dependence, adult antisocial behavior and cannabis and cocaine abuse/dependence were obtained at personal interview. Logistic regression analyses in the entire sample and within monozygotic (MZ) twin pairs were conducted in SAS. In the entire sample, measures of maximal caffeine use, heavy caffeine use, and caffeine-related toxicity and dependence were significantly and positively associated with all seven psychiatric and substance use disorders. However, within MZ twin pairs, controlling for genetic and family environmental factors, these associations, while positive, were all non-significant. These results were similar when excluding twins who denied regular caffeine use. Maximal lifetime caffeine intake and caffeine-associated toxicity and dependence are moderately associated with risk for a wide range of psychiatric and substance use disorders. Analyses of these relationships within MZ twin pairs suggest that most of the observed associations are not causal. Rather, familial factors, which are probably in part genetic, predispose to both caffeine intake, toxicity and dependence and the risk for a broad array of internalizing and externalizing disorders.

    Self-esteem, coping strategies and perceived social support play a role in the adaptive functioning of the human being: they allow the adjustment of the subject to his/her environment. These dimensions could be protective factors regarding multiple risks associated with adolescent development, and particularly substance use. Thus our objective was twofold: to evaluate self-esteem, coping strategies and perceived social support in adolescents and young adults with a cannabis dependence in comparison with subjects from the general population; to establish the correspondence between these psychological dimensions and the patients' substance use pattern. Data from 43 young patients (36 males; mean age=19.6±3), consulting for their cannabis dependence, and 50 young adults from the general population (39 males; mean age=19.7±3.4) were included. Participants completed the Rosenberg Self-Esteem Inventory, the Social Self-Esteem Inventory of Lawson, the Coping Inventory for Stressful Situation of Endler & Parker, and the Perceived Social Support Questionnaire of Sarason. The MINI was administered to evaluate cannabis abuse or dependence; a semi-structured clinical interview was given to determine psychoactive substance use. Between-group comparisons (two independent sample t-tests) showed that the patients had significantly lower scores on global (P=0.002) and social (P=0.035) self-esteem, task-oriented coping (Pself-esteem scores (P=0.028). Moreover, polysubstance misuse is associated with low distraction-avoidant coping scores. No association was found between clinical scores and tobacco and alcohol uses variables. These results suggest that cannabis dependent patients may present a lack in individual and interpersonal resources. This clinical study underscores the potential contribution of maladaptive coping to the development or maintenance of substance use in young adulthood. Copyright © 2013 L’Encéphale, Paris.

    3,4-Methylenedioxymethamphetamine (MDMA, ecstasy) is one of the most widely abused illegal drugs. Some users self-report euphoria and an increased perception and feeling of closeness to others. When taken in warm environments, MDMA users may develop acute complications with potential fatal consequences. In rodents, MDMA increases locomotor activity and, depending on ambient temperature, may produce a dose-dependent, potentially lethal hyperthermia. Like most other recreational drugs, MDMA is frequently taken in combination with other substances including tobacco, EtOH, marijuana, amphetamines, cocaine and, caffeine. Although polydrug use is very common, the understanding of the effects of this multiple substance use, as well as the analysis of consequences of different drug-drug associations, received rather little attention. The purpose of this review is to summarize our current knowledge about the changes on MDMA-related behavior, pharmacology, and neurotoxicity associated with co-consumption of other drugs of abuse and psychoactive agents.

    The aim of this study was to investigate the link between violence, crime, and sexual behavior among patients with substance-related disorder admitted to a specialized inpatient care unit. This was a cross-sectional study using a questionnaire on socio-demographic characteristics, drug of choice (DOC), questions about sexual behavior, and instruments to evaluate the severity of dependence (SADD, DAST, FTND), level of impulsivity (BIS-11), and a screening sex addiction scale. The sample consisted of 587 adult subjects, of which 82.3% were men, 66.4% had used cocaine (sniffed and smoked) as their DOC, 24.4% had a history with the criminal justice system, 26.8% had committed crimes, 19.3% had engaged in violent behavior, and 12.2% had been involved in drug trafficking. In this sample, crime was strongly associated with various sexual behaviors and the severity of substance dependence.

    Full Text Available A associação entre transtornos alimentares e dependência de substâncias é freqüente na prática clínica. Apesar de já existirem dados sugestivos de que essa associação possa sinalizar maior severidade nos distúrbios psiquiátricos e clínicos das pacientes, poucas pesquisas avaliaram sua influência no tratamento. Oitenta mulheres dependentes de álcool e drogas que procuraram tratamento em um programa exclusivo para mulheres foram avaliadas por meio da Entrevista Clínica Estruturada para o DSM-IV (SCID, do ASI, e de um questionário padronizado para a coleta de dados sociodemográficos e relativos ao uso de substâncias psicoativas. As 27 (33,75% pacientes que tinham transtornos alimentares presentes (grupo com TA foram comparadas com as 53 (66,25% que não tinham essa comorbidade (grupo sem TA. Os resultados mostraram que o grupo com TA teve problemas com drogas de maneira mais precoce, era significativamente mais jovem e tinha maior severidade no uso destas que o grupo sem TA. As diferenças encontradas, bem como a alta prevalência dos transtornos alimentares não formais, enfatizam a importância de uma avaliação detalhada dos transtornos alimentares em pacientes dependentes de substâncias psicoativas que buscam tratamento. A fim de planejar abordagens terapêuticas efetivas, essas diferenças e, principalmente, a influência da comorbidade entre transtornos alimentares e dependência de substâncias psicoativas no tratamento da dependência química precisam ser investigadas no futuro.The co-occurrence of eating disorders and substance use disorders is frequent in clinical settings. Although there are some data suggesting that this co-occurrence may signal greater psychiatric disturbances and greater medical risks, few studies have evaluated its impact on treatment course.

    Full Text Available Natural psychoactive substances have fascinated the curious mind of shamans, artists, scholars and laymen since antiquity. During the twentieth century, the chemical composition of the most important psychoactive drugs, that is opium, cannabis, coca and "magic mushrooms", has been fully elucidated. The mode of action of the principal ingredients has also been deciphered at the molecular level. In the past two decades, the use of herbal drugs, such as kava, kratom and Salvia divinorum, began to spread beyond their traditional geographical and cultural boundaries. The aim of the present paper is to briefly summarize recent findings on the psychopharmacology of the most prominent psychoactive natural products. Current knowledge on a few lesser-known drugs, including bufotenine, glaucine, kava, betel, pituri, lettuce opium and kanna is also reviewed. In addition, selected cases of alleged natural (or semi-natural products are also mentioned.

    Van der Waals (vdW) interaction between two-dimensional crystals (2D) can trap substances in high pressurized (of order 1 GPa) on nanobubbles. Increasing the adhesion between the 2D crystals further enhances the pressure and can lead to a phase transition of the trapped material. We found that the shape of the nanobubble can depend critically on the properties of the trapped substance. In the absence of any residual strain in the top 2D crystal, flat nanobubbles can be formed by trapped long hydrocarbons (that is, hexadecane). For large nanobubbles with radius 130 nm, our atomic force microscopy measurements show nanobubbles filled with hydrocarbons (water) have a cylindrical symmetry (asymmetric) shape which is in good agreement with our molecular dynamics simulations. This study provides insights into the effects of the specific material and the vdW pressure on the microscopic details of graphene bubbles.

  2. Metabolism of the new psychoactive substances N,N-diallyltryptamine (DALT) and 5-methoxy-DALT and their detectability in urine by GC-MS, LC-MSn, and LC-HR-MS-MS.

    N,N-Diallyltryptamine (DALT) and 5-methoxy-DALT (5-MeO-DALT) are synthetic tryptamine derivatives commonly referred to as so-called new psychoactive substances (NPS). They have psychoactive effects that may be similar to those of other tryptamine derivatives. The objectives of this work were to study the metabolic fate and detectability, in urine, of DALT and 5-MeO-DALT. For metabolism studies, rat urine obtained after high-dose administration was prepared by precipitation and analyzed by liquid chromatography-high-resolution mass spectrometry (LC-HR-MS-MS). On the basis of the metabolites identified, several aromatic and aliphatic hydroxylations, N-dealkylation, N-oxidation, and combinations thereof are proposed as the main metabolic pathways for both compounds. O-Demethylation of 5-MeO-DALT was also observed, in addition to extensive glucuronidation or sulfation of both compounds after phase I transformation. The cytochrome P450 (CYP) isoenzymes predominantly involved in DALT metabolism were CYP2C19, CYP2D6, and CYP3A4; those mainly involved in 5-MeO-DALT metabolism were CYP1A2, CYP2C19, CYP2D6, and CYP3A4. For detectability studies, rat urine was screened by GC-MS, LC-MS(n), and LC-HR-MS-MS after administration of low doses. LC-MS(n) and LC-HR-MS-MS were deemed suitable for monitoring consumption of both compounds. The most abundant targets were a ring hydroxy metabolite of DALT, the N,O-bis-dealkyl metabolite of 5-MeO-DALT, and their glucuronides. GC-MS enabled screening of DALT by use of its main metabolites only.

    2-Amino-1-(4-bromo-2,5-dimethoxyphenyl)ethanone hydrochloride (bk-2C-B) has recently emerged as a new psychoactive substance (NPS). It is most commonly consumed orally, although there are indications that it might also be ingested by inhalation or 'smoking'. Information about the stability of bk-2C-B when exposed to heat is unavailable and the potential for pyrolytic degradation and formation of unknown substances available for inhalation prompted an investigation using a simulated 'meth pipe' scenario. Twelve products following pyrolysis of bk-2C-B were detected and verified by organic synthesis of the corresponding standards. In addition, 2-amino-1-(4-iodo-2,5-dimethoxyphenyl)ethanone hydrochloride (bk-2C-I) was characterized for the first time and subjected to pyrolysis as well. Similar products were formed, which indicated that the replacement of the bromo with the iodo substituent did not affect the pyrolysis pattern under the conditions used. Two additional products were detected in the bk-2C-I pyrolates, namely 1-(2,5-dimethoxyphenyl)-ethanone and 1-iodo-4-ethenyl-5-methoxyphenol. The potential ingestion of pyrolysis products with unknown toxicity adds an element of concern. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

    Full Text Available Introduction & Objective: There are several close links between substance dependency and mental disorders. Many people who regularly abuse drugs are also diagnosed with psychiatric disorders and vice versa. The high prevalence of this comorbidity has been documented in several studies, although most of the research has been carried out in only a few countries and the cultural validity of the data is unknown. Thus the aim of this study was the comparative investigation of mental disorders in drug dependent and non drug dependent persons in city of Hamadan.Materials & Methods: This study was a descriptive comparative research. 106 men aged 18 to 51 who sought treatment at addiction rehabilitation department of Hamadan were recruited in this study. Also 106 men in the same age range were matched with the first group. Data were collected through structured clinical interview for DSM-IV-TR and SCL 90-R questionnaire. Data were analyzed using t-test and correlation coefficient test.Results: The rate and severity of mental disorders in 9 studied Categories of disorders—phobia, anxiety, somatization, psychotism, depression, paranoid thoughts, aggression, interpersonal sensitivity and obsession-compulsion—were significantly higher among the addicts than the normal group.The level of severity was higher in depression, paranoid thoughts and interpersonal sensitivity than the other disorders. 63.5% of addicts suffered from some psychological disorders while the figures for no addicts were 28.8%. The prevalence of co-morbid psychiatric disorders varied with the pattern of addicts.Conclusion: This study showed that persons with substance dependence display more signs of psycho pathology and mental disorders in comparison with non- substance dependent people.(Sci J Hamadan Univ Med Sci 2011;18(3:22-28

    Personality traits such as pathological engagement in approach behaviors, high levels of impulsivity and heightened negative affect are consistently observed in substance dependent individuals (SDI). The clinical course of addiction has been shown to differ between sexes. For example, women increase their rates of consumption of some drugs of abuse more quickly than men. Despite the potential influence of personality and sex on features of addiction, few studies have investigated the interaction of these factors in substance dependence. Fifty-one SDI (26 males, 25 females) and 66 controls (41 males, 25 females) completed the Behavioral Inhibition/Behavioral Activation System (BIS/BAS) Scales, the Barratt Impulsiveness Scale, and the Positive and Negative Affect Schedule (PANAS-X). Data were analyzed with 2×2 ANCOVAs testing for main effects of group, sex and group by sex interactions, adjusting for education level. Significant group by sex interactions were observed for BAS scores [F(1,116)=7.03, pImpulsiveness [F(1,116)=6.11, pimpulsivity followed by male SDI, male controls, and finally female controls. SDI scored higher on negative affect [F(1,116)=25.23, pwomen than men [F(1,116)=14.03, pimpulsivity in SDI women relative to SDI men and control women suggest that personality traits that have been previously associated with drug use may be modulated by sex. These factors may contribute to differences in the disease course observed in male compared to female drug users. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    In recent years, use of psychoactive synthetic stimulants has grown rapidly. 5-(2-Aminopropyl)indole (5-IT) is a synthetic drug associated with a number of fatalities, that appears to be one of the newest 3,4-methylenedioxymethamphetamine (MDMA) replacements. Here, the monoamine-releasing properties of 5-IT, its structural isomer 6-(2-aminopropyl)indole (6-IT), and MDMA were compared using in vitro release assays at transporters for dopamine (DAT), norepinephrine (NET), and serotonin (SERT) in rat brain synaptosomes. In vivo pharmacology was assessed by locomotor activity and a functional observational battery (FOB) in mice. 5-IT and 6-IT were potent substrates at DAT, NET, and SERT. In contrast with the non-selective releasing properties of MDMA, 5-IT displayed greater potency for release at DAT over SERT, while 6-IT displayed greater potency for release at SERT over DAT. 5-IT produced locomotor stimulation and typical stimulant effects in the FOB similar to those produced by MDMA. Conversely, 6-IT increased behaviors associated with 5-HT toxicity. 5-IT likely has high abuse potential, which may be somewhat diminished by its slow onset of in vivo effects, whereas 6-IT may have low abuse liability, but enhanced risk for adverse effects. Results indicate that subtle differences in the chemical structure of transporter ligands can have profound effects on biological activity. The potent monoamine-releasing actions of 5-IT, coupled with its known inhibition of MAO A, could underlie its dangerous effects when administered alone, and in combination with other monoaminergic drugs or medications. Consequently, 5-IT and related compounds may pose substantial risk for abuse and serious adverse effects in human users. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Introduction: The aim of present research was the comparison of maladaptive meta cognition beliefs among substance abusers and non abusers. Methods: For this purpose 70 substance abusers and 70 individuals from the general population by purposive sampling participated in this research and responded to meta cognition questionnaire. For analysis data multiple analysis of variance (MANOVA and discriminant analysis were run. Results: MANOVA revealed that there was significant difference in linier combination of dependent variables (meta cognitive beliefs among two groups also, analysis of dependent variables lonely showed that two groups were significantly different in Positive meta cognitive beliefs, "Negative meta cognitive beliefs", "lack of cognitive confidence", "need to control of thoughts", and "cognitive self-consciousness". Also, the discriminant analysis indicated that three meta-cognitive factors included “negative meta cognitive beliefs", "need to control of thoughts" and "cognitive self-consciousness" were significant predictors to discriminate substance abusers. Conclusion: With consideration of the results it can be concluded that substance abusers have more maladaptive beliefs and these maladaptive beliefs can lead to susceptibility toward substance abuse and staying in this disorder. It is hoped that psychotherapists can be more useful in treating and staying in this research.

    Dialectical behavior therapy (DBT) identifies emotion dysregulation as central to the dangerous impulsivity of borderline personality disorder (BPD) including substance use disorders, and DBT targets improved emotion regulation as a primary mechanism of change. However, improved emotion regulation with DBT and associations between such improvement and behavioral outcomes such as substance use has not been previously reported. Thus, the goal of this study was to assess for improvement in emotion regulation and to examine the relationship between improvements in the emotion regulation and substance use problems following DBT treatment. Emotion regulation as assessed by the Difficulties in Emotion Regulation Scale, depressed mood as assessed by the Beck Depression Inventory, and their associations with substance use frequency were investigated in 27 women with substance dependence and BPD receiving 20 weeks of DBT in an academic community outpatient substance abuse treatment program. Results indicated improved emotion regulation, improved mood, and decreased substance use frequency. Further, emotion regulation improvement, but not improved mood, explained the variance of decreased substance use frequency. This is the first study to demonstrate improved emotion regulation in BPD patients treated with DBT and to show that improved emotion regulation can account for increased behavioral control in BPD patients. SIGNIFICANCE AND FUTURE RESEARCH: Emotion regulation assessment is recommended for future studies to further clarify the etiology and maintenance of disorders associated with emotional dysregulation such as BPD and substance dependence and to further explore emotion regulation as a potential mechanism of change for clinical interventions.

    Predicting the popularity of and harm caused by psychoactive agents is a serious problem that would be difficult to do by a single simple method. However, because of the growing number of drugs it is very important to provide a simple and fast tool for predicting some characteristics of these substances. We were inspired by the Google Flu Trends study on the activity of the influenza virus, which showed that influenza virus activity worldwide can be monitored based on queries entered into the Google search engine. Our aim was to propose a fast method for ranking the most popular and most harmful drugs based on easily available data gathered from the Internet. We used the Google search engine to acquire data for the ranking lists. Subsequently, using the resulting list and the frequency of hits for the respective psychoactive drugs combined with the word "harm" or "harmful", we estimated quickly how much harm is associated with each drug. We ranked the most popular and harmful psychoactive drugs. As we conducted the research over a period of several months, we noted that the relative popularity indexes tended to change depending on when we obtained them. This suggests that the data may be useful in monitoring changes over time in the use of each of these psychoactive agents. Our data correlate well with the results from a multicriteria decision analysis of drug harms in the United Kingdom. We showed that Google search data can be a valuable source of information to assess the popularity of and harm caused by psychoactive agents and may help in monitoring drug use trends.

    in large urban regions of Brazil in 2005. The data were collected by means of questionnaires. The chi-square automatic interaction classification tree technique was used to study the use of condoms among interviewees of both sexes and other contraceptive methods among women, at the time of the last vaginal sexual intercourse. RESULTS: Among young and middle-aged adults of both sexes and young men in stable relationships, condom use was less frequent among those who said they used psychoactive substances (alcohol and/or illegal drugs. The possible modulating effect of psychoactive substances on contraceptive practices among mature women seems to be more straightforward, compared to the more subtle effects observed among younger women, for whom the different social classes they belonged to seemed to play a more important role. CONCLUSIONS: Despite the limitations resulting from an exploratory study, the fact that this was a representative sample of the urban population of Brazil and not from vulnerable populations, reinforces the need to implement integrated public policies directed towards the general population, with regard to preventing drug consumption, alcohol abuse, sexually transmitted infections, HIV/AIDS and unwanted pregnancy and promoting sexual and reproductive health.

    pelos meninos como pelas meninas, muitas vezes em idades bem precoces.INTRODUCTION: Concern over the consumption of psychoactive substances by teenagers has given rise to a great wordwide effort to produce information about this phenomenon. This study set out to investigate the prevalence of consumption of legal and illegal psychoactive substances, its distribution by age, sex and age at first experience of them, among teenage pupils in county, Ribeirão Preto, SP, Southeastern Brazil. MATERIAL AND METHOD: A self-applicable questionnaire duly adapted and submitted to a reliability test was applied to a proportional sample of 1,025 teenagers enrolled in 8th, 9th, 10th and 11th grads at public and private city schools. The questionnaire contained questions about the use of ten classes of psychoactive substances, demographic questions and validation information, as well as questions about the perception and intrinsic behavior related to drug consumption. RESULTS: The sample of 88.9% had consumed alcoholic beverages sometime in their lives, 37.7% had used tobacco, 31.1% solvents, 10.5% medicines, 6.8% marihuana, 2.7% cocaine, 1.6% hallucinogens, and 0.3% of the sample had consumed some opiate substance. The rates of consumption increased with age for all substances; however, the use of tobacco and of illegal substances was less intense during the later years of adolescence. As to sex distribution, boys consumed more than girls, except for medicines, with girls consuming barbiturates, amphetamines and tranquilizers in proportions similar to or higher than those observed among boys. Age at first experience showed that access to psychoactive substances occurred at very early ages. CONCLUSIONS: Experimenting with psychoactive substances, whether legal or illegal, is a frequent phenomenon during adolescence, both among boys and girls, often at very early ages.

  14. The ethnobotany of psychoactive plant use: a phylogenetic perspective

    Full Text Available Psychoactive plants contain chemicals that presumably evolved as allelochemicals but target certain neuronal receptors when consumed by humans, altering perception, emotion and cognition. These plants have been used since ancient times as medicines and in the context of religious rituals for their various psychoactive effects (e.g., as hallucinogens, stimulants, sedatives. The ubiquity of psychoactive plants in various cultures motivates investigation of the commonalities among these plants, in which a phylogenetic framework may be insightful. A phylogeny of culturally diverse psychoactive plant taxa was constructed with their psychotropic effects and affected neurotransmitter systems mapped on the phylogeny. The phylogenetic distribution shows multiple evolutionary origins of psychoactive families. The plant families Myristicaceae (e.g., nutmeg, Papaveraceae (opium poppy, Cactaceae (peyote, Convolvulaceae (morning glory, Solanaceae (tobacco, Lamiaceae (mints, Apocynaceae (dogbane have a disproportionate number of psychoactive genera with various indigenous groups using geographically disparate members of these plant families for the same psychoactive effect, an example of cultural convergence. Pharmacological traits related to hallucinogenic and sedative potential are phylogenetically conserved within families. Unrelated families that exert similar psychoactive effects also modulate similar neurotransmitter systems (i.e., mechanistic convergence. However, pharmacological mechanisms for stimulant effects were varied even within families suggesting that stimulant chemicals may be more evolutionarily labile than those associated with hallucinogenic and sedative effects. Chemically similar psychoactive chemicals may also exist in phylogenetically unrelated lineages, suggesting convergent evolution or differential gene regulation of a common metabolic pathway. Our study has shown that phylogenetic analysis of traditionally used psychoactive plants

    The effects of major depressive disorder (MDD) on the course of substance dependence may differ depending on the temporal relationship of depression to dependence. We investigated the effects of MDD on the outcome of substance dependence under 3 circumstances: (1) lifetime onset of MDD prior to lifetime onset of dependence onset, (2) current MDD occurring during a period of abstinence, and (3) current MDD during substance use that exceeded the expected effects of intoxication or withdrawal. A sample of 250 inpatients with DSM-IV cocaine, heroin, and/or alcohol dependence were followed up at 6, 12, and 18 months. The Psychiatric Research Interview for Substance and Mental Disorders (PRISM) was used to make DSM-IV diagnoses. Using Cox proportional hazards models, stable remissions (those lasting at least 26 weeks) from DSM-IV cocaine, heroin, and/or alcohol dependence and from use were studied, as well as subsequent relapses of dependence and use. Patients with current substance-induced MDD were less likely to remit from dependence (adjusted hazards ratio, 0.11) than patients with no baseline MDD. A history of MDD prior to lifetime onset of substance dependence also reduced the likelihood of remission relative to the absence of such a history (adjusted hazard ratio, 0.49). Major depressive disorder during sustained abstinence predicted dependence relapse (adjusted hazards ratio, 3.07) and substance use after hospital discharge compared with those without abstinence MDD (adjusted hazards ratio, 1.45). The timing of depressive episodes relative to substance dependence served as an important factor in the remission and relapse of substance dependence and substance use.

    The study seeks to increase understanding of the use of psychoactive prescription drugs among persons suspected of driving under the influence (DUI). We studied whether the use of prescribed psychoactive medication was associated with DUI, and examined the difference in the use of prescription drugs between DUI recidivists and those arrested only once. In this register-based study, persons suspected of DUI (n=29470) were drawn from the Register of DUI suspects, and an age- and gender-matched reference population (n=30043) was drawn from the Finnish general population. Data on prescription drug use was obtained by linkage to the National Prescription Register. The associations of DUI arrest and use of psychoactive prescription drugs in different DUI groups (findings for alcohol only, prescription drugs, prescription drugs and alcohol, illicit drugs) were estimated by using mixed-effect logistic regression. The use of psychoactive prescription drugs and DUI appeared to be strongly associated, with DUI suspects significantly more likely to use psychoactive prescription drugs compared to the reference population. Gender differences existed, with the use of benzodiazepines being more common among female DUI suspects. Moreover, DUI recidivists were more likely to use psychoactive prescription drugs compared to those arrested only once. In addition to alcohol and/or illicit drug use, a significant proportion of DUI suspects were using psychoactive prescription drugs. When prescribing psychoactive medication, especially benzodiazepines, physicians are challenged to screen for possible substance use problems and also to monitor for patients' alcohol or illicit drug use while being medicated.

Se concluye que esas substancias comprometen la salud de ellos y el desarrollo de sus actividades laborales.The study had as object the psychoactive substance use by the workers of nursing and its relation with the work. The objective was to analyze the work conditions as unleash factor of the use of drugs by the nursing worker. The theoretical referential was structuralized from the concept of drugs and clarifying models of the drug dependency, supported in the conceptions of Dejours (1999 and Laurell & Noriega (1989. Descriptive study of qualitative approach with 40 citizens workers of nursing of medical clinic of a university hospital in the City of Rio de Janeiro - Brazil, carried through in 2005 and 2006. As instrument of data collection, was used the half-structuralized interview. The results showed that the psychoactive substance use by the professionals in the work place can be related with the conditions of overload work and with the easiness of access and that such substances compromise their health and the development of their labor activities.

    Homelessness is associated with increased prevalence of mental health disorders, substance use disorders and mental health/substance use disorder comorbidity in the United States of America. Gay, bisexual and other men who have sex with men (MSM) living in the United States are at increased risk for homelessness, and have also evidenced elevated mental health and substance use disorder prevalence relative to their non-MSM male counterparts. Secondary analysis of data from a randomised controlled trial estimating the diagnostic prevalence of substance use/mental health disorder comorbidity among a sample of homeless, substance-dependent MSM (DSM-IV verified; n = 131). The most prevalent substance use/mental health disorder comorbidities were stimulant dependence comorbid with at least one depressive disorder (28%), alcohol dependence comorbid with at least one depressive disorder (26%) and stimulant dependence comorbid with antisocial personality disorder (25%). Diagnostic depression and antisocial personality disorder both demonstrated high rates of prevalence among homeless, substance-dependent (particularly stimulant and alcohol dependent) MSM.

    HIV's effects on episodic memory have not been compared systematically between male and female substance-dependent individuals. We administered the Brief Visuospatial Memory Test-Revised (BVMT-R) to 280 substance-dependent HIV+ and HIV- men and women. Groups were comparable on demographic, substance use, and comorbid characteristics. There were no significant main effects of sex or HIV serostatus on BVMT-R performance, but HIV+ women performed significantly more poorly on delayed recall. This effect was most prominent among cocaine-dependent HIV+ women. Our findings are consistent with recent speculation that memory impairment may be more common among HIV+ women, particularly those with a history of cocaine dependence.

    Full Text Available Background: Marital adjustment is considered as a part of social well-being. Disturbed marital relationship can directly affect the disease adjustment and the way they face disease outcomes and complications. It may adversely affect physical health, mental health, the quality-of-life and even economic status of individuals. Aim: The aim of this study was to compare the marital adjustment among patients with substance dependence, schizophrenia and bipolar affective disorder. Materials and Methods: The sample consisted of each 30 patients with substance dependence, bipolar affective disorder and schizophrenia, diagnosed as per international classification of diseases-10 diagnostic criteria for research with a minimum duration of illness of 1 year were evaluated using marital adjustment questionnaire. The data was analyzed using parametric and non-parametric statistics. Results: Prevalence of poor marital adjustment in patients with schizophrenia, bipolar affective disorder and substance dependence was 60%, 70% and 50% respectively. There was a significant difference on overall marital adjustment among substance dependence and bipolar affective disorder patients. There was no significant difference on overall marital adjustment among patients with substance dependence and schizophrenia as well as among patients with schizophrenia and bipolar affective disorder. On marital adjustment domains, schizophrenia patients had significantly poor sexual adjustment than substance dependence patients while bipolar affective disorder patients had significantly poor sexual and social adjustment compared with substance dependence patients. Conclusion: Patients with substance dependence have significant better overall marital adjustment compared with bipolar affective disorder patients. Patients with substance dependence have significantly better social and sexual adjustment than patients with bipolar affective disorder as well as significantly better sexual

    In Latin America, substance related disorders are highly prevalent and one of the treatment strategies is the Therapeutic Communities (TCs), however, in Latin America there is scarce data about this treatment strategies, their quality, drop-out rates and patient satisfaction. Based on a previous study in 5 Latin American countries, the TCs who had a score equal or higher than 9 according to the De Leon criteria which are some fundamental items that the TCs should meet, were selected to carry out a descriptive and retrospective study of qualitative and quantitative characteristics of the TCs. Data from 58 TCs in 5 countries were included, with a sample of 1414 patients interviewed, of which most were single men, with no hospitalization history in a therapeutic community. Marijuana was the most commonly substance used in the 30 days prior to hospitalization, with 78% of interviewees referring alcohol consumption in the last 6 months and an average onset of psychoactive substances at 16 years of age. A 79% of the patients interviewed perceived some improvement during their stay in the TCs. The less fulfilled Quality Indicators by the TCs were "Requesting a professional qualification to former addicts that belonged to the program" and "Work as part of the therapeutic program". Among the reasons for discharge found in the database, 44% were due to therapeutic discharge with fulfillment of the treatment plan and 44% withdraws. The user satisfaction with TCs, in terms of infrastructure and quality are quite high, as the fulfillment of essential quality items, however, the follow up information to evaluate effectiveness of the treatment is poor or in some cases unknown.

    To analyze the association between low saliva flow rates and the use of psychoactive drugs among the elderly. A cross-sectional study was carried out with 267 elderly people from 60 to 74 years of age who lived in a borough of the city of Londrina, Paraná State, Brazil. Individuals with high functional dependence or restricted to bed were excluded. Saliva flow rate was the dependent variable with values under the first tercile being considered as low flow rates (less than 0.44 ml/min). The continuous use of psychoactive drugs (antidepressant, antiepileptic, sedative, antipsychotic, hypnotic or sedative-hypnotic drugs) was the independent variable. Multivariate analysis was performed taking into account gender, age and smoking status. The majority of the elderly were women (80.5%), with a mean age of 66.5 years. Use of psychoactive drugs was observed among 31 elderly (11.6%). Mean saliva flow rate was 0.76 ml/min, lower among users of psychoactive drugs (0.67 ml/min). In the multivariate analysis, use of psychoactive drugs was associated with low saliva flow rates (psychoactive drugs and low saliva flow rates in this group of independent and non-institutionalized elderly. These conclusions stress the need of a rational use of these drugs, particularly among the elderly.

This study was aimed to determine the comorbidity of substance dependency in patients with cluster B personality disorders. Method: This cross-sectional study was performed on 96 patients (71 males and 25 females referring to Farabi Hospital, Kermanshah, Iran .The data were gathered using a questionnaire. Data analysis was performed by SPSS software. Results: Data analysis revealed that borderline personality disorder with one year substance abuse, combination of histrionic, borderline, narcissistic and anti-social disorders with two years of substance abuse, borderline personality disorder or a combination of borderline, histrionic, narcissistic and anti-social disorders with three years of substance abuse and combination of narcissistic, borderline, histrionic and anti-social disorders in patients with more than three years of substance dependency had the highest prevalence. Narcissistic personality disorder in patients with no attempts to quit and combination of histrionic, borderline, narcissistic and anti-social disorders in patients with two or three attempts to quit had the highest prevalence. Conclusion: The results showed a relationship between substance dependency and cluster B personality disorders. Considering the prevalence of personality disorders among drug abusers, psychological and psychiatric interventions along with medication are necessary in substance abuse treatment centers.

    A new trend among users of new psychoactive substances' the consumption of "herbal highs": plant parts containing psychoactive substances. Most of the substances extracted from herbs, in old centuries were at the centre of religious ceremonies of ancient civilizations. Currently, these herbal products are mainly sold by internet web sites and easily obtained since some of them have no legal restriction. We reviewed psychoactive effects and neuropharmacology of the most used "herbal highs" with characterized active principles, with studies reporting mechanisms of action, pharmacological and subjective effects, eventual secondary effects including intoxications and/or fatalities Method: The PubMed database was searched using the following key.words: herbal highs, Argyreia nervosa, Ipomoea violacea and Rivea corymbosa; Catha edulis; Datura stramonium; Piper methysticum; Mitragyna speciosa. Psychoactive plants here reviewed have been known and used from ancient times, even if for some of them limited information still exist regarding subjective and neuropharmacological effects and consequent eventual toxicity when plants are used alone or in combination with "classical" drugs of abuse. Some "herbal highs" should be classified as harmful drugs since chronic administration has been linked with addiction and cognitive impairment; for some others taking into consideration only the recent trends of abuse, studies investigating these aspects are lacking.

    2014-11-01

    Full Text Available Objective: The aim of this study was to evaluate the early maladaptive schemas and coping strategies of substance dependents. We hypothesized that substance dependents would have more maladaptive schemas and would use less adaptive coping strategies than healthy controls. Methods: Thirty-two patients diagnosed with substance dependence and 31 control subjects without any psychiatric disorders were evaluated via Young Schema Questionnaire-SF, COPE, and Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I. Results: The substance dependents scored significantly higher than the control group in nine out of fourteen early maladaptive schemas. In terms of coping strategies, the substance dependents scored significantly lower than the control group in positive reinterpretation and growth, seeking social support for instrumental reasons, active coping, and seeking social support for emotional reasons, and significantly higher in behavioral disengagement and alcohol-drug disengagement subscales. Moreover, alcohol-drug disengagement type of coping style was significantly predicted by schemas of emotional deprivation, emotional inhibition, enmeshment/dependence, entitlement/ insufficient self-control, abandonment/instability, punitiveness, defectiveness/shame, vulnerability to harm or illness, and unrelenting standards/hypercriticalness. Discussion: Current study showed that the substance dependents had more maladaptive unhealthy core beliefs and ineffective coping strategies than a non-clinical control group. These findings support the importance of early maladaptive schemas which might be the underlying factor for the dependence problem, and might prevent the person to deal with the problem with more active and problem focused coping strategies.

  14. A critical examination of the definition of 'psychoactive effect' in Australian drug legislation.

    Barratt, Monica J; Seear, Kate; Lancaster, Kari

    2017-02-01

    As the number of new 'psychoactive substances' detected globally has risen exponentially, the policy response of assessing and prohibiting each new substance individually has become increasingly unworkable. In an attempt to disrupt the availability of new as-yet-unscheduled substances, Ireland (2010), Poland (2011), Romania (2012), New Zealand (2013), Australia (2015) and the United Kingdom (2016) have enacted generic or blanket ban legislation that prohibits all 'psychoactive substances' that are not already regulated or belong to exempt categories. How such generic legislation defines 'psychoactive substance' is therefore crucial. While there is a growing critical literature relating to blanket bans of 'psychoactive substances', the Australian legislation is yet to be described or critically analysed. In this commentary, we aim to draw the attention of local and international drug policy scholars to Australia's newest legislative approach to 'psychoactive substances'. Using the Australian experience as a case study, we first describe and trace the origins of this generic banning approach, especially focusing on how 'psychoactive effect' came to be defined. Then, we critically examine the assumptions underpinning this definition and the possibilities silenced by it, drawing on the work of poststructuralist and critical scholars. In doing so, we explore and raise a series of questions about how this legislation works to stabilise drugs, drug harms and drug effects, as well as addiction realities; how the category of 'psychoactive substances' is produced through this legislation; and some of the material-discursive effects which accompany this rendering of the 'problem'. We offer this commentary not as a comprehensive discussion of each of these elements but rather as a starting-point to promote further discussion and debate within the drug policy field. To this end, we conclude with a suggested research agenda that may help guide such future work. Copyright © 2016

    HIV+ individuals with and without substance use disorders make significantly poorer decisions when information about the probability and magnitude of wins and losses is not available. We administered the Game of Dice Task, a measure of decision making under risk that provides this information explicitly, to 92 HIV+ and 134 HIV- substance-dependent men and women. HIV+ participants made significantly poorer decisions than HIV- participants, but this deficit appeared more prominent among HIV+ women. These data indicate that decision making under risk is impaired among HIV+ substance-dependent individuals (SDIs). Potential factors for the HIV+ women's relatively greater impairment are discussed.

    Full Text Available The objective of this study was to estimate the prevalence of depression with and without substance dependence and examine the effect of risk factors on subsequent disorders among a cohort of young adults in the US Child Welfare System (CWS. We used longitudinal data for 834 young adults age 18–21 from the National Survey of Child and Adolescent Well-being. Depressive symptoms and substance use were measured at baseline (age 11–15; diagnoses of depression and substance dependence were identified at the last wave of data collection (age 18–21. Likelihood of subsequent depression with or without substance dependence was three times higher for those with clinically significant depressive symptoms at baseline. Frequent use of substances at baseline significantly increased the likelihood of subsequent depression with comorbid substance dependence compared to depression alone. These results support screening youth in the CWS at younger ages for both depressive symptoms and substance use with the hope that these disorders can be detected earlier.

    Most studies of attention deficit hyperactivity disorder (ADHD) in the substance dependence literature have assessed ADHD as a single, categorical entity. This approach limits characterization across the spectrum of ADHD symptomatology and may mask differences across the two core domains of ADHD symptoms-hyperactive-impulsive (HI) and inattention (IN). Further, it is unclear whether relations of HI and IN symptoms to substance dependence extend across drug classes and to the general population. This cross-sectional study investigated associations of lifetime ADHD HI and IN symptom levels to individual classes of lifetime substance dependence (alcohol, nicotine, depressants, opioids, stimulants, cannabis, hallucinogens, polysubstance) in a population-based sample of 34,653 American adults. HI and IN were associated with the majority of dependence diagnoses in a linear pattern, such that each additional symptom was associated with a proportional increase in odds of dependence. After adjusting for the overlap between symptom domains, both HI and IN uniquely associated with alcohol, nicotine, and polysubstance dependence, but only HI uniquely associated with dependence on illicit substances. These findings suggest that individuals in the general population with elevated levels of ADHD (particularly HI) symptoms are at risk for various forms of substance dependence and could benefit from preventive interventions.

    The objective of the study was to determine which psychoactive prescription drugs are illegally obtained and through which ways of acquisition. OPPIDUM is an annual national study. It is based on specialized care centers that included subjects presenting a drug dependency or under opiate maintenance treatment. All their psychoactive substances consumed are reported. This work focuses on the different ways of acquisition specially the illegal ways of acquisition (bought on the street, forged prescription, stolen, given, internet). For each medication illegally obtained, a ratio has been calculated (number of illegal acquisitions divided by the number of described acquisitions). In 2008, 5542 subjects have been included and have described the consumption of 11 027 substances including 63.8% of prescription drugs. Among them, 11% were illegally obtained. The different illegal acquisition ways were 'street market' (77.6%), 'gift' (16.6%), 'theft' (2.3%), 'forged prescription' (2.3%), and 'internet' (0.7%). The third first drugs illegally obtained were high dosage buprenorphine, methadone, and clonazepam. Some prescription drugs, less consumed, have an important ratio of illegal acquisition like ketamine, flunitrazepam, morphine, trihexyphenidyl, or methylphenidate. This study confirms that theft, forged prescription and internet are few used and permits to highlight diversion of prescription drugs. It is important to inform healthcare professionals on the different prescription drugs that are illegally obtained. © 2011 The Authors Fundamental and Clinical Pharmacology © 2011 Société Française de Pharmacologie et de Thérapeutique.

    2008-01-01

    Annual pharmaceutical expenditures in prisons increases dramatically and the rising costs of psychoactive drugs have especially contributed to this. These drugs are often prescribed in order to find therapeutic uses in the field of personality disorders, addictions, and dysfunctional behaviours that are not included in the authorized indications (compassionate use). This study has enabled a detailed description of the use of psychoactive drugs at the Madrid III prison, a centre with one of the lowest levels of pharmaceutical expenditure in this autonomous community. During a two-week period, all prescriptions of psychoactive drugs were collected and registered along with data of several possible conditioning factors. 20.5% of the population was receiving some kind of psychoactive drug; 76% of those inmates undergoing treatment were receiving one or two substances; 65% were taking anxiolytics, 38% antidepressants and 27% antipsychotics. The total amount of psychoactive drugs consumed was 9,840 defined daily doses, 46% of which were anxiolytics, 17% antidepressants and 14% antipsychotics. The total cost of the fortnight's treatment was euros 5,379 with a saving of euro 611 due to requesting and selecting offers carried out by the pharmacist. 72% of the costs were spent on anti-psychotics and the newer psychoactive drugs, representing 66% of the prescriptions, accounted for 98% of expenditure. The prescriber was one of the key influential factors over the amount, type and cost of the treatments. There are signs that compassionate use of current antipsychotics and antiepileptics, and newer antidepressants are a main cause of the dramatic increase in the costs, with cost-efficiency not always clearly demonstrated. These results are not an isolated fact restricted only to prisons, as demonstrated by consumption data published by the National Health System in the same year.

  20. Generic legislation of new psychoactive drugs.

    2013-03-01

    New psychoactive drugs (NPDs, new psychoactive substances) enter the market all the time. However, it takes several months to ban these NPDs and immediate action is generally not possible. Several European countries and drug enforcement officers insist on a faster procedure to ban NPDs. Introduction of generic legislation, in which clusters of psychotropic drugs are banned in advance, has been mentioned as a possible solution. Here we discuss the pros and cons of such an approach. First, generic legislation could unintentionally increase the expenditures of enforcement, black market practices, administrative burden and health risks for users. Second, it may have a negative impact on research and the development of new treatments. Third, due to the complexity of generic legislation, problems in the enforcement are anticipated due to lack of knowledge about the chemical nomenclature. Finally, various legal options are already available to ban the use, sale and trade of NPDs. We therefore conclude that the currently used scientific benefit-risk evaluation should be continued to limit the adverse health effects of NPDs. Only in emergency cases, where fatal incidents (may) occur, should this approach be overruled.

  1. The detrimental effects of emotional process dysregulation on decision making in substance dependence

    Directory of Open Access Journals (Sweden)

    Anna eMurphy

    2012-11-01

    Full Text Available Substance dependence is complex and multifactorial, with many distinct pathways involved in both the development and subsequent maintenance of addictive behaviours. Various cognitive mechanisms have been implicated, including impulsivity, compulsivity and impaired decision-making. These mechanisms are modulated by emotional processes, resulting in increased likelihood of initial drug use, sustained substance dependence, and increased relapse during periods of abstinence. Emotional traits, such as sensation seeking, are risk factors for substance use, and chronic drug use can result in further emotional dysregulation via effects on reward, motivation and stress systems. We will explore theories of hyper and hypo sensitivity of the brain reward systems that may underpin motivational abnormalities and anhedonia. Disturbances in these systems contribute to the biasing of emotional processing toward cues related to drug use at the expense of natural rewards, which serves to maintain addictive behaviour, via enhanced drug craving. We will additionally focus on the sensitization of the brain stress systems that result in negative affect states that continue into protracted abstinence that is may lead to compulsive drug taking. We will explore how these emotional dysregulations impact upon decision-making controlled by goal-directed and habitual action selections systems, and, in combination with a failure of prefrontal inhibitory control, mediate maladaptive decision-making observed in substance dependent individuals such that they continue drug use in spite of negative consequences. An understanding of the emotional impacts on cognition in substance dependent individuals may guide the development of more effective therapeutic interventions.

Analysis of variance indicated that Whites were experiencing more nicotine and alcohol dependency and psychological distress than others, but African Americans and Hispanics were experiencing more cocaine dependency than Whites. Ordinary least squares regression revealed that nicotine dependency is significantly related to the psychological distress of Whites. Alcohol dependency is significantly associated with the psychological distress of three groups. Culturally competent programs are suggested.

    The dependent coverage expansion (DCE) enacted through the Affordable Care Act increased health insurance coverage among young adults. Increasing insurance coverage in this age group has the potential for unintended consequences on risky substance use. Repeated cross-sectional surveys were used to compare change in substance use during the period the DCE was implemented in the 19-25year old target age group (Pre-DCE n=15,772, Post-DCE n=22,719) with contemporaneous change in a slightly older age group that was not targeted by the policy (Pre-DCE=19,851, Post-DCE n=28,157). Outcomes include 11 measures of alcohol, illicit drug and cigarette use. Statistical controls were included for demographic and socioeconomic factors and for early initiation of substance use to adjust for historical trends in developmental trajectories. Risky substance use decreased in young adults relative to the older age group over the period that the DCE was implemented. However, statistical adjustment for initiation of substance use prior to age 18, which is prior to exposure to the DCE, accounted for the differences between the age groups. In adjusted models, associations between the DCE and substance use outcomes range from 0.96 to 1.08 with p-values ranging from 0.330 to 0.963. Historical trends in initiation of substance use prior to age 18, not the DCE, account for change in risky substance use among 19-25year olds relative to 26-34year olds. The evidence does not support the suggestion that health insurance coverage would increase risky substance use among young adults. Copyright © 2017 Elsevier B.V. All rights reserved.

    Psychoactive substance abuse is prevalent among medical undergraduates of Pakistan, India & Western countries which can adversely affect the physical & psychological grooming of a medical undergraduate thus threatening to compromise their role as future physicians & health-care providers in the society. The objective of the present cross-sectional study was to explore the prevalence and patterns of psychoactive substance/drug consumption among undergraduate students of a public sector medical college in Abbottabad. Seven hundred and eighty participants after informed consent were requested to fill a questionnaire seeking information about their demographics, patterns & behaviours regarding ten common psychoactive substances of abuse including (Cigarettes, Benzodiazepines, naswar, cannabis, alcohol, amphetamine, opium, cocaine, heroin & organic solvents). Overall students who responded were 698 (89.48%). One hundred and fifty (21.49%) admitted to the use of a psychoactive substance in past or at present. Majority users (71.33%) were males. Overall (81.33%) users were living in hostel or a rented apartment. Substance abuse was more prevalent among senior students, i.e., 30.06% & 24.24% in 4th year & final year MBBS respectively. Majority of the consumers, i.e., 93 (62%) were falling in an age group between 15-20 years. Main reasons behind substance abuse were: psychological stress (49.33%) and pleasure seeking (42.67%). Substances/drugs used by students in order of preference were Cigarettes 115 (76.67%), Benzodiazepines 48 (32%), naswar 42 (28%), Cannabis 41 (27.33%), Alcohol 24 (16%), Amphetamine 22 (14.67%), Opium 15 (10%), Cocaine 14 (9.33%), Heroin 11 (7.33%) & Organic solvents 05 (3.33%). Use of more than one substance was observed in 70 (46.67%) students. It is concluded that prevalence of cigarette smoking, naswar, benzodiazepines, cannabis & alcohol is high among medical undergraduates in Abbottabad which is a matter of concern. Efforts are needed to create

    The present study sought to evaluate the influence of interactive journaling on criminal recidivism and identify significant predictors of recidivism among a sample of 183 male inmates incarcerated in a local jail facility randomly assigned to either an interactive journaling condition or a control group. All participants met DSM-IV-TR criteria for substance dependence, had their current offense indicate substance involvement, and had a minimum of one previous arrest in the prior 12 months. The recidivism rate (51%), in terms of subsequent bookings within a 12-month period, for the journaling group was significantly lower than the recidivism rate (66%) for the control group, χ(2)(1, 183) = 4.13, p journaling vs. placebo), and employment status. Interactive journaling appears to show promise as a brief treatment intervention strategy for substance dependence in local jail settings and may have the potential for reducing recidivism.

    To understand the experiences of women with a history of substance dependence when they attempted to gain parenting support. Becoming a mother provides a window of opportunity to support women with a substance dependence make changes to their lives and the way they will parent their infants and young children. Yet there are many barriers and a constant fear of the removal of their children from their care. Focus groups were conducted using a qualitative interpretive descriptive approach to enable exploration of the women's experiences as mothers with infants and young children. A series of three focus groups were facilitated with three to six women per group. Thirteen women who were substance dependent participated in this study. Semi-structured interviews guided the collection of data. Thematic content analysis was used to work with the data. Four themes were identified: (1) feelings of guilt, (2) judged by others, (3) normalising and (4) support and learning to be a mother. The mothers expressed alienation from mainstream health services. Providing parenting and child health services, which avoid mothers feeling judged by the staff and other mothers, is an important step to enabling these women to appropriately and sensitively care for their infants and young children. Midwives and nurses working with mothers and their infants and young children are well positioned to support women who are or have experienced substance dependence. Working with this group of mothers requires the development of a therapeutic relationship to provide optimum support, education and, if necessary, intervention. © 2014 John Wiley & Sons Ltd.

  16. Comorbid depression, antisocial personality, and substance dependence: Relationship with delay discounting.

    Moody, Lara; Franck, Christopher; Bickel, Warren K

    2016-03-01

    Within the field of addiction, as many as four-fifths of individuals in treatment for substance use disorder have co-existing lifetime psychopathology and as high as two-thirds have current psychopathology. Among substance-dependent individuals, excessive delay discounting is pervasive. Despite evidence of excessive discounting across substance use disorders, few studies have investigated the impact of co-occurring psychopathologies and SUD on delay discounting. We compared delay discounting in currently abstaining substance users with (a) SUD (n=166), (b) SUD and managed major depressive disorder (MDD; n=44), (c) SUD and antisocial personality disorder (APD; n=35), (d) SUD and managed MDD and APD (n=22) and (e) no SUD or co-occurring psychopathology (n=60). All groups with SUD discounted future delayed rewards significantly more than healthy controls (p<0.001 in each case, d=0.686, 0.835, 1.098 and 1.650, respective to groups a-d above). Individuals with both APD and SUD and individuals with MDD, APD, and SUD discounted future rewards significantly more than substance users without comorbid psychopathology (p=0.029, d=0.412 and p<0.001, d=0.964, respectively). Overall, individuals with multiple psychopathologies in addition to substance use have exacerbated deficits in discounting of the future, above and beyond that observed in substance use alone. Increased discounting in combined substance and psychopathology profiles suggest a greater chance of treatment failure and therefore may necessitate individualized treatment using adjunctive interventions to achieve better treatment outcomes.

    Discussion: Current study showed that the substance dependents had more maladaptive unhealthy core beliefs and ineffective coping strategies than a non-clinical control group. These findings support the importance of early maladaptive schemas which might be the underlying factor for the dependency problem, and might prevent the person to deal with the problem with more active and problem focused coping strategies.

    Recent animal and human studies reveal distinct cognitive and neurobiological differences between opiate and stimulant addictions; however, our understanding of the common and specific effects of these two classes of drugs remains limited due to the high rates of polysubstance-dependence among drug users. The goal of the current study was to identify multivariate substance-specific markers classifying heroin dependence (HD) and amphetamine dependence (AD), by using machine-learning approaches. Participants included 39 amphetamine mono-dependent, 44 heroin mono-dependent, 58 polysubstance dependent, and 81 non-substance dependent individuals. The majority of substance dependent participants were in protracted abstinence. We used demographic, personality (trait impulsivity, trait psychopathy, aggression, sensation seeking), psychiatric (attention deficit hyperactivity disorder, conduct disorder, antisocial personality disorder, psychopathy, anxiety, depression), and neurocognitive impulsivity measures (Delay Discounting, Go/No-Go, Stop Signal, Immediate Memory, Balloon Analogue Risk, Cambridge Gambling, and Iowa Gambling tasks) as predictors in a machine-learning algorithm. The machine-learning approach revealed substance-specific multivariate profiles that classified HD and AD in new samples with high degree of accuracy. Out of 54 predictors, psychopathy was the only classifier common to both types of addiction. Important dissociations emerged between factors classifying HD and AD, which often showed opposite patterns among individuals with HD and AD. These results suggest that different mechanisms may underlie HD and AD, challenging the unitary account of drug addiction. This line of work may shed light on the development of standardized and cost-efficient clinical diagnostic tests and facilitate the development of individualized prevention and intervention programs for HD and AD.

    Background Adolescents with attention-deficit/hyperactivity disorder (ADHD) are known to be at significantly greater risk for the development of substance use disorders (SUD) compared to peers. Impulsivity, which could lead to higher levels of drug use, is a known symptom of ADHD and likely accounts, in part, for this relationship. Other factors, such as a biologically increased susceptibility to substance dependence (addiction), may also play a role. Objective This report further examines the relationships between childhood ADHD, adolescent- onset SUD, and substance abuse and substance dependence in adulthood. Method Individuals with childhood ADHD and non-ADHD controls from the same population-based birth cohort were invited to participate in a prospective outcome study. Participants completed a structured neuropsychiatric interview with modules for SUD and a psychosocial questionnaire. Information on adolescent SUD was obtained retrospectively, in a previous study, from medical and school records. Associations were summarized using odds ratios (OR) and 95% CIs estimated from logistic regression models adjusted for age and gender. Results A total of 232 ADHD cases and 335 non-ADHD controls participated (mean age, 27.0 and 28.6 years, respectively). ADHD cases were more likely than controls to have a SUD diagnosed in adolescence and were more likely to have alcohol (adjusted OR 14.38, 95% CI 1.49–138.88) and drug (adjusted OR 3.48, 95% CI 1.38–8.79) dependence in adulthood. The subgroup of participating ADHD cases who did not have SUD during adolescence were no more likely than controls to develop new onset alcohol dependence as adults, although they were significantly more likely to develop new onset drug dependence. Conclusions Our study found preliminary evidence that adults with childhood ADHD are more susceptible than peers to developing drug dependence, a disorder associated with neurological changes in the brain.

    Full Text Available Objectives: From the psychological point of view, coping strategies and attitudes have considerable effects on people’s tendency towards risky behavior, including opioid substance abuse. Dysfunctional attitudes are attitudes and beliefs that predispose the individual toward depression and psychological disorder, generally speaking. Usually, people use three types of coping strategies when confronting stressful situations problem-focused, emotion-focused and avoidance strategies. This study therefore aimed to compare dysfunctional attitudes and coping strategies in substance-dependent & healthy individuals. Methods: A causal-comparative study was conducted. The population under study consisted of 100 addicts attending Robat-Karim’s addiction rehabilitation centers who were selected through simple random sampling. Another 100 ordinary individuals were matched with the addicts. The dysfunctional attitudes scale and the coping strategies questionnaire was used to collect data. Multivariate analysis of variance was used to analyze data. Results: The two groups differed significantly in their dysfunctional attitudes and problem-focused and emotion-focused coping strategies. Substance-dependent individuals applied emotion-focused coping more and had greater dysfunctional attitudes than the healthy ones, and the latter applied problem-focused strategies more. Discussion: Based on our results, addicts have greater dysfunctional attitudes than non-addicts. Therefore, better treatment and rehabilitation results may be obtained by preparing grounds for appropriate psychological interventions and coping strategies in substance-dependent individuals.

The relationship between the substance abuse and MS is complex and the literature is sparse. Objectives: The present research was aimed to study the prevalence and predictors of MS among outpatients with substance dependence. Materials and Methods: Patients with substance dependence were recruited from a deaddiction center in North India, who attended outpatient clinic from 1 st January, 2010-31 st December, 2010. MS was assessed using International Diabetes Federation (IDF criteria. Results: Out of 250 subjects, 34 (13.6% of the subjects met the IDF criteria for MS and highest being in alcohol group (21.6%. The commonest abnormality was increased triglycerides (TG; 54% and increased waist circumference (36.8%. Age, body weight, body mass index, and obesity were significant predictor of MS. Conclusion: MS was highest in subjects with alcohol dependence with the commonest abnormality of TG and blood pressure. Hence, routine screening is advisable in this population to address emerging MS.

    Nicotine produces core symptoms of substance dependence (craving and withdrawal) without any psychotic symptoms. The psychopharmacological structure of craving is hypothesized to be constituted by three components: the primary reinforcing property of a substance, the secondary reinforcing property of that substance (conditioned aspects of the environment, such as contextual or specific cues associated with substance taking), and the negative affective motivational property during withdrawal (i.e. the desire to avoid the dysphoric withdrawal symptoms elicits craving). Among the three components, the primary reinforcing property of a substance forms the most fundamental factor for establishing substance dependence. Sensitization or reverse tolerance observed in locomotor activity of animals, which had been believed to be a methamphetamine psychosis model, is demonstrated to reflect the establishment of conditioned reinforcement. Finally, non-substance-related addiction such as gambling, internet, and sex is discussed. From the aspect of the above hypothetical psychopharmacological structure of craving, the most significant difference between substance dependence and non-substance-related addiction is that the primary reinforcing property of non-substance reward is relatively intangible in comparison with that of a substance of abuse.

    For smokers with substance use disorders (SUD), perceived barriers to quitting smoking include concerns unique to effects on sobriety as well as usual concerns. We expanded our Barriers to Quitting Smoking in Substance Abuse Treatment (BQS-SAT) scale, added importance ratings, validated it, and then used the importance scores to predict smoking treatment response in smokers with substance use disorders (SUD) undergoing smoking treatment in residential treatment programs in two studies (n=184 and 340). Both components (general barriers, weight concerns) were replicated with excellent internal consistency reliability. Construct validity was supported by significant correlations with pretreatment nicotine dependence, smoking variables, smoking self-efficacy, and expected effects of smoking. General barriers significantly predicted 1-month smoking abstinence, frequency and heaviness, and 3-month smoking frequency; weight concerns predicted 1-month smoking frequency. Implications involve addressing barriers with corrective information in smoking treatment for smokers with SUD. Copyright © 2016 Elsevier Inc. All rights reserved.

    This chapter examines the psychostimulant actions of methylxanthines, with a focus on the consequences of their excessive use. Consumption of methylxanthines is pervasive and their use is often associated with that of substances known to produce dependence and to have abuse potential. Therefore, the consequences of this combined use are taken into consideration in order to evaluate whether, and to what extent, methylxanthines could influence dependence on or abuse of other centrally active substances, leading to either amplification or attenuation of their effects. Since the methylxanthine that mostly influences mental processes and readily induces psychostimulation is caffeine, this review mainly focuses on caffeine as a prototype of methylxanthine-produced dependence, examining, at the same time, the risks related to caffeine use.

    Full Text Available The acceptance and respect of the rules governing society and the family unit are essential pillars for the development of a therapeutic program for people with substance dependence disorders. This study proposes a double objective using the scales of the MMPI-2 detectors of mismatches emphasising: what information can provide and what the diagnostic accuracy of the MMPI-2 is to assess these mismatches. As a reference, psychopathic deviation (Pd, social introversion (Si, antisocial practices (ASP, social responsibility (Re, social unrest (SOD, introversion/low positive emotion (PSY-INTR, family problems (FAM, and conjugal stress (MDS were taken. Of the 226 participants, 113 are people with substance dependence and 113 have no dependence or any pathology. Their differences and diagnostic accuracy through the ROC curve were analysed. The results showed different contribution and diagnostic accuracy of the scales.

    Sensory information processing and alexithymia are two important factors in determining behavioral reactions. Some studies explain the effect of the sensitivity of sensory processing and alexithymia in the tendency to substance abuse. Giving that, the aim of the current study was to compare the styles of sensory information processing and alexithymia between substance-dependent people and normal ones. The research method was cross-sectional and the statistical population of the current study comprised of all substance-dependent men who are present in substance quitting camps of Masal, Iran, in October 2013 (n = 78). 36 persons were selected randomly by simple randomly sampling method from this population as the study group, and 36 persons were also selected among the normal population in the same way as the comparison group. Both groups was evaluated by using Toronto alexithymia scale (TAS) and adult sensory profile, and the multivariate analysis of variance (MANOVA) test was applied to analyze data. The results showed that there are significance differences between two groups in low registration (P processing and difficulty in describing emotions (P process sensory information in a different way than normal people and show more alexithymia features than them.

    The medial prefrontal cortex, especially the dorsal anterior cingulate cortex (ACC), has long been implicated in cognitive control and error processing. Although the association between ACC and behavior has been established, it is less clear how ACC contributes to dysfunctional behavior such as substance dependence. Evidence from neuroimaging studies investigating ACC function in substance users is mixed, with some studies showing disengagement of ACC in substance dependent individuals (SDs), while others show increased ACC activity related to substance use. In this study, we investigate ACC function in SDs and healthy individuals performing a change signal task for monetary rewards. Using a priori predictions derived from a recent computational model of ACC, we find that ACC activity differs between SDs and controls in factors related to reward salience and risk aversion between SDs and healthy individuals. Quantitative fits of a computational model to fMRI data reveal significant differences in best fit parameters for reward salience and risk preferences. Specifically, the ACC in SDs shows greater risk aversion, defined as concavity in the utility function, and greater attention to rewards relative to reward omission. Furthermore, across participants risk aversion and reward salience are positively correlated. The results clarify the role that ACC plays in both the reduced sensitivity to omitted rewards and greater reward valuation in SDs. Clinical implications of applying computational modeling in psychiatry are also discussed.

    Purpose To assess changes in inmates’ misuse of substances from pre- to post-incarceration. Methods In Study 1, professionals (n = 162) and laypersons (n = 50) predicted how jail inmates’ substance misuse would change from pre-incarceration to post-release. In Study 2, a longitudinal study of 305 jail inmates, we examined actual changes in substance use and dependence from pre-incarceration to the first year post-incarceration, as well as whether changes varied as a function of demographic, criminal justice, treatment, and personality factors. Results Professionals and laypersons predicted little change in substance misuse whereas, in fact, inmates’ frequency of substance use and dependence decreased substantially from pre-incarceration to post-release. Sharper decreases were observed for inmates who were female, younger, more educated, serving longer sentences, enrolled in substance abuse treatment, high in shame-proneness, and low in criminogenic thinking. Race, first time incarceration, transfer to other correctional facilities, mandated community supervision (probation), and guilt-proneness did not predict changes in substance use or dependence. Conclusions Although substance misuse decreased, this remains a population high in need of substance abuse treatment both upon arrest and at one year post-incarceration; 60% of former inmates met at least one DSM-IV criterion for substance dependence at one year post-release.

    Caffeine is the most widely consumed psychoactive substance in the world and is a legal stimulant that is readily available to children. The potential for dependence on caffeine has been debated. Presently, due to a paucity of clinical evidence on caffeine dependence, no such diagnosis is included in the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, Text Revision (DSM-IV-TR). Although in recent studies, a subset of the general population was found to demonstrate caffeine dependence. It is valuable for psychiatrists and primary care physicians to recognize caffeine dependence as a clinical syndrome, since some people are distressed by their caffeine use and feel they can not control or stop their problematic use.

    Despite emerging evidence for the comorbidity of posttraumatic stress disorder (PTSD) and migraine, few studies have examined the relation of PTSD and migraine, particularly among clinical populations at-risk for both conditions (e.g., substance-dependent patients). This study examined the role of PTSD symptoms in migraine and headache-related disability within a sample of 153 substance-dependent inpatients (37.25% female, Mean age 36.46). PTSD symptoms predicted both migraine and headache-related disability above and beyond gender, depression and anxiety symptoms, the experience of a Criterion A traumatic event, and current alcohol use disorder. Findings highlight the strong association between migraine and PTSD symptoms in a unique population at risk for both conditions.

    The current study evaluates a therapy for substance-dependent perpetrators of partner violence. Sixty-three males arrested for partner violence within the past year were randomized to a cognitive behavioral substance abuse-domestic violence (SADV; n = 29) or a drug counseling (DC; n = 34) condition. Seventy percent of offenders completed eight core sessions with no differences between SADV and DC conditions in the amount of substance or aggression at pretreatment. SADV participants had fewer cocaine-positive toxicology screens and breathalyzer results during treatment, were less likely to engage in aggressive behavior proximal to a drinking episode, and reported fewer episodes of violence than DC participants at posttreatment follow-up. SADV shows promise in decreasing addiction and partner violence among substance-dependent male offenders. © 2017 American Association for Marriage and Family Therapy.

    Physical exercise is useful for individuals with mental disorders with additional substance dependency or abuse. Many exercise actively while in institution, but a major challenge is to continue after discharge. Many patients are isolated and lonely and find it hard to motivate themselves to exercise on their own. In Sogn og Fjordane county, Norway, the problem was dealt with through a training program of exercise contacts. These are social support persons who were thus assigned a new function. By way of a 40-hour course that covered physical activity, psychological problems, and substance abuse and dependency, lay people were trained to help people in their home environment. By the end of 2005, almost 300 exercise contacts, living in 25 of the 26 municipalities in the county, had passed the course exam. Their expertise is highly demanded and more courses have been requested. The course evaluations have been quite positive. In particular, the practical instructions about how to exercise, in combination with updated theory on substance abuse/dependence and mental disorders, were highly appreciated. Clients were helped to continue with regular physical activity and they have appreciated the improved physical and mental health that was associated with regular exercise. Moreover, the exercise contacts help clients break social isolation and have given them access to the common social arenas.

Concluiu-se que o consumo moderado de qualquer substância psicoativa não influenciou os níveis de auto-estima dos estudantes deste nível de instrução.This study aimed to correlate students' self-esteem in the sixth year of basic education in Chiguayante state schools in Concepción-Chile with psychoactive substance consumption in the family. This non-experimental, correlational and cross-sectional study was carried out in a sample of 303 children. An instrument with sociodemographic data and Garcia's Self-Concept Inventory in School (1995 were used for data collection. In general, 89.1% of the students displayed high global self-esteem. This result was repeated when the group of children who reported on psychoactive substance consumption (no matter which mode in the family was compared with the group of children that did not mention this situation. As we did not observe any significant diffferences between the groups, we concluded that moderate consumption of any psychoactive substance would not influence the self-esteem of students at this educational level.

    Full Text Available Introduction: This study investigated the role of thought suppression, meta- cognitive factors, and negative emotions in predicting of substance dependency disorder. Method: Subjects were 70 patients with substance dependence disorder and 70 normal individuals (total 140. Substance dependants were selected of outpatient treatment centers and the normal sample was selected of the general population too. Sampling methods in both samples were convenience sampling. All people were assessed by MCQ-30, White Bear Suppression Inventory, and Beck’s Anxiety and Depression Questionnaires. For data analysis, discriminant analysis were used. Results: Negative meta-cognitive beliefs about worry, depression, and thought suppression were the most significant predictors of substance dependence disorder. Conclusion: Through meta-cognitive beliefs, thought suppression and negative emotion (especially depression, substance dependency disorder can be predicted. Based on this model can be used to take a substance dependency disorder prevention approach and psychotherapy approach (based on cognitive and meta-cognitive therapies. In addition, the findings of this research can be applied in clinical and counseling environments to help substance dependant clients.

This study aimed to formulate hypotheses regarding psychological, social and family variables that can be constructed as motivations or subjective barriers for the early seeking of formal treatment. METHODS: A qualitative study was conducted in an intentional sample (selected through saturation and variety of types of 13 substance-dependent individuals who sought treatment. In-depth, semi-structured interviews were conducted using open questions, and the transcribed data were subjected to qualitative analysis. RESULTS: Four types of spontaneous harm reduction measures were identified, according to the subjective logic of each participant: having some periods at rest (not using and recovering from adverse effects; caretaking by close acquaintances (relatives, partners, drug dealers and alcoholic beverage sellers; selectivity regarding substance source, type and means of administration; establishing "healthy" limits of ingestion. CONCLUSIONS: The measures identified might represent barriers to the early seeking of treatment but might also represent spontaneous learning of abilities beneficial to future treatment. Health care professionals should take into consideration their existence and should address them in clinical settings. Issues representative of the formulated categories should be presented in structured questionnaires used in future quantitative studies of barriers to treatment in this population.

    Attentional biases toward substance-related stimuli might play a contributing role in addictive behaviors. This study investigated the selective attention to substance-related stimuli in heroin dependents receiving methadone maintenance therapy. Thirty outpatients receiving methadone maintenance treatment for heroin dependence and 38 healthy controls completed a visual probe task with concurrent eye movement monitoring. The results showed that the heroin group reacted faster to probes associated with substance-related pictures than neutral pictures, and they directed more initial fixations and maintained longer initial fixation durations toward substance-related pictures than neutral pictures. However, attentional bias was not correlated with addiction severity in the heroin group. These findings suggest that attentional bias towards substance-related cues occurs in heroin dependents, although this bias might not be associated with the severity of drug-using behavior.

    The study aimed to collect information concerning the increasing use of new psychoactive substances, commonly sold through online shops as 'Internet drugs' or 'legal highs', or in terms of masked products such as 'bath salts' and 'plant food'. The Karolinska Institutet and Karolinska University Laboratory and the Swedish Poisons Information Centre have initiated a project called 'STRIDA' aiming to monitor the occurrence and trends of new psychoactive substances in Sweden, and collect information about their clinical symptoms, toxicity and associated health risks. A liquid chromatographic-tandem mass spectrometric (LC-MS/MS) multi-component method has been developed, currently allowing for the determination of > 80 novel psychoactive compounds or metabolites thereof. This study focused mainly on the particular drug substances identified and the population demographics of the initial STRIDA cases. In urine and/or blood samples obtained from 103 consecutive cases of admitted or suspected recreational drug intoxications in mostly young subjects (78% were ≤ 25 years, and 81% were males) presenting at emergency departments all over the country, psychoactive substances were detected in 82%. The substances comprised synthetic cannabinoids ('Spice'; JWH analogues), substituted cathinones ('bath salts'; e.g. butylone, MDPV and methylone) and tryptamines (4-HO-MET), plant-based substances (mitragynine and psilocin), as well as conventional drugs-of-abuse. In 44% of the cases, more than one new psychoactive substance, or a mixture of new and/or conventional drugs were detected. The initial results of the STRIDA project have documented use of a broad variety of new psychoactive substances among mainly young people all over Sweden.

    Full Text Available Abstract Most persons in drug treatment smoke cigarettes. Until drug treatment facilities systematically treat their patients' tobacco use, millions will flow through the drug treatment system, overcome their primary drug of abuse, but die prematurely from tobacco-related illnesses. This paper reviews the literature on the health benefits of quitting smoking for drug treatment patients, whether smoking causes relapse to other drug or alcohol abuse, the treatment of tobacco dependence, and good and bad times for quitting smoking among drug treatment patients. It also presents a conceptual model and recommendations for treating tobacco in substance abuse treatment, and provides references to internet and paper-copy tools and information for treating tobacco dependence. At present, research on tobacco treatment in drug treatment is in its infancy. Although few drug treatment programs currently offer formal services, many more will likely begin to treat nicotine dependence as external forces and patient demand for these services increases. In the absence of clear guidelines and attention to quality of care, drug treatment programs may adopt smoking cessation services based on cost, convenience, or selection criteria other than efficacy. Because research in this field is relatively new, substance abuse treatment professionals should adhere to the standards of care for the general population, but be prepared to update their practices with emerging interventions that have proven to be effective for patients in drug treatment.

Analisa-se a distribuição do consumo dessas substâncias segundo as classes sociais, numa amostra de adolescentes escolares de Ribeirão Preto, SP, Brasil. MATERIAL E MÉTODO: Um questionário auto-aplicável, adaptado e submetido a um teste de confiabilidade, foi aplicado a uma amostra proporcional de 1.025 adolescentes matriculados na oitava série do primeiro grau e primeiro, segundo e terceiro anos do segundo grau, das escolas públicas e privadas da cidade. O questionário continha questões sobre o uso de dez classes de drogas. Utilizou-se a adaptação de um modelo que identifica 5 frações de classe social (burguesias empresarial, gerencial e pequena burguesia, proletariado e subproletariado, a partir de indicadores que situam os indivíduos dentro das relações sociais de produção. RESULTADOS: As três frações da burguesia foram mais representadas que as outras na população de adolescentes escolares do que na população geral. Não houve diferenças na distribuição do consumo de álcool e tabaco pelas classes sociais, embora se observe uma tendência de maior prevalência nos extremos da escala social. Já o consumo de substâncias ilícitas foi maior nas burguesias e menor no proletariado. CONCLUSÕES: Embora o consumo de substâncias lícitas não tenha diferido entre as classes sociais, o maior consumo de substâncias ilícitas pelos mais ricos provavelmente se deveu ao maior custo desses produtos do que o álcool e o tabaco.INTRODUCTION: Many of the epidemiological studies on the consumption of legal and illegal psychoactive substances have included the evaluation of the influence of social context on the levels of prevalence of this consumption using indirect social indicators such as family income, and

    2006-01-01

    Similar to patients with orbitofrontal cortex lesions, substance dependent individuals (SDI) show signs of impairments in decision-making, characterised by a tendency to choose the immediate reward at the expense of severe negative future consequences. The somatic-marker hypothesis proposes that decision-making depends in many important ways on neural substrates that regulate homeostasis, emotion and feeling. According to this model, there should be a link between abnormalities in experiencing emotions in SDI, and their severe impairments in decision-making in real-life. Growing evidence from neuroscientific studies suggests that core aspects of substance addiction may be explained in terms of abnormal emotional guidance of decision-making. Behavioural studies have revealed emotional processing and decision-making deficits in SDI. Combined neuropsychological and physiological assessment has demonstrated that the poorer decision-making of SDI is associated with altered reactions to reward and punishing events. Imaging studies have shown that impaired decision-making in addiction is associated with abnormal functioning of a distributed neural network critical for the processing of emotional information, including the ventromedial cortex, the amygdala, the striatum, the anterior cingulate cortex, and the insular/somato-sensory cortices, as well as non-specific neurotransmitter systems that modulate activities of neural processes involved in decision-making. The aim of this paper is to review this growing evidence, and to examine the extent of which these studies support a somatic-marker model of addiction. PMID:18615136

    Substance dependent (SD) relative to non-dependent (ND) individuals exhibit an attenuated reward positivity, an electrophysiological signal believed to index sensitivity of anterior cingulate cortex (ACC) to rewards. Here we asked whether this altered neural response reflects a specific devaluation of monetary rewards relative to drug-related rewards by ACC. We recorded the reward positivity from SD and ND individuals who currently smoke, following an overnight period of abstinence, while they engaged in two feedback tasks. In a money condition the feedback indicated either a monetary reward or no reward, and in a cigarette condition the feedback indicated either a drug-related reward or no reward. Overall, cigarette relative to monetary rewards elicited a larger reward positivity. Further, for the subjects who engaged in the money condition first, the reward positivity was smaller for the SD compared to the ND participants, but for the subjects who engaged in the cigarette condition first, the reward positivity was larger for the SD compared to the ND participants. Our results suggest that the initial category of feedback "primed" the response of the ACC to the alternative feedback type on subsequent trials, and that SD and ND individuals responded differently to this priming effect. We propose that for people who misuse addictive substances, the prospect of obtaining drug-related rewards engages the ACC to exert control over extended behaviors.

    This qualitative empirical study explores the ritual use of ayahuasca in the treatment of addictions. Ayahuasca is an Amazonian psychedelic plant compound created from an admixture of the vine Banisteriopsis caapi and the bush Psychotria viridis. The study included interviews with 13 therapists who apply ayahuasca professionally in the treatment of addictions (four indigenous healers and nine Western mental health professionals with university degrees), two expert researchers, and 14 individuals who had undergone ayahuasca-assisted therapy for addictions in diverse contexts in South America. The study provides empirically based hypotheses on therapeutic mechanisms of ayahuasca in substance dependence treatment. Findings indicate that ayahuasca can serve as a valuable therapeutic tool that, in carefully structured settings, can catalyze neurobiological and psychological processes that support recovery from substance dependencies and the prevention of relapse. Treatment outcomes, however, can be influenced by a number of variables that are explained in this study. In addition, issues related to ritual transfer and strategies for minimizing undesired side-effects are discussed.

    Powdery drugs such as cocaine and heroin are frequently adulterated or diluted predominantly to obtain more doses and to increase the drug dealer's profits, but also to enhance, to modify or to oppose drug effects. The aim of this report is to provide an overview of the recent scientific literature on medicines as well as on new psychoactive substances, used as cutting agents (i.e. pharmacologically active adulterants) and on the related adverse health effects on consumers, possibly due to the synergistic effect of the adulterants laced with substances of abuse. A literature search up to January 2017 was performed on MEDLINE, Scopus and Web of Science and reports and documents of international agencies or institutions were also searched. Pharmacologically active substances such as: paracetamol, caffeine, dextromethorphan, clenbuterol for heroin; levamisole, phenacetine, lidocaine, hydroxyzine and diltiazem for cocaine; caffeine and phentermine for amphetamine, have been identified over the years. Furthermore, since cocaine and morphine (this latter as a precursor of heroin) are both extracted from natural products, some impurities and minor alkaloids can be present in the final preparation. In this context, it is worth considering that new psychoactive substances are also used as cutting agents. The wide availability of illicit psychotropic drugs is the most serious hazard threatening consumers. Indeed emergency departments are often responsible in evaluating damages caused not only by the base substance, but also by other eventual compounds added to mimic or antagonize drug effects or simply dilute the drug amount, with a possible harmful synergic toxic action.

    Previous studies have found a negative association between health insurance and nonmedical use of prescription drugs (NMUPD), and abuse or dependence on prescription drugs (ADPD); and mixed associations between health insurance and use of substance abuse treatment (SAT). However, effect of health insurance in the specific subgroups of population is largely unknown. To estimate the relationship between health insurance and (1) NMUPD, (2) ADPD, and (3) use of SAT services among 12-64 years old, noninstitutionalized individuals and to see if these relationships are different in different subgroups of population. This study used cross-sectional survey data from 2007 National Survey on Drug Use and Health. Bivariate and multiple logistic regression analyses were conducted. In 2007, self-reported prevalence of NMUPD was approximately 10% (N=15,509,703). In multivariate analysis, NMUPD was negatively associated with health insurance, age, race other than non-Hispanic White, education, marital status, and income ($40,000-$74,999). Past year use of tobacco and alcohol were positively associated with NMUPD. Among those with private health insurance, Hispanics and individuals with family income less than $20,000 and $40,000-$74,999 were more likely prone to NMUPD than others. High school graduates with public health insurance were less likely prone to NMUPD. Approximately, 13% of nonmedical users reported ADPD (N=2,011,229). Health insurance and age were negatively associated with ADPD. However, people who were unmarried, reported fair/poor health, and used tobacco were more likely to report ADPD. Lastly, the use of substance abuse treatment programs was approximately 73% and 76% between NMUPD and ADPD population, respectively. Health insurance was not associated with use of substance abuse treatment. Individuals with high school education were 2.6 times more likely to use substance abuse treatment than the college graduates. Additionally, no significant interaction effects

    Substance abuse is a health problem with serious psychological and psychiatric dimensions and multiple social and economic consequences. Cancer is a disease that threatens not only life and physical integrity but mental health as well. Oncology patients suffer from mental disorders in high rates, especially from depression and anxiety. The role of substance abuse in the pathogenesis of cancer is studied systematically, since there are research data supporting the mutagenic effects of certain substances. It has been supported that a possible dysregulation of the immune system is linked to the oncogenic processes induced by substances of abuse. Specifically, opioids are the first addictive substances that have been identified as oncogenic factors. However, conflicting results have been offered by experimental animal studies, which showed that opioids, such as morphine, depending on the dosage administered, may not only enhance the process of tumor growth, but also inhibit it. Additionally, research data indicate that the use of cannabis may be associated with cancer, either as an independent factor or in relation to other mutagenics, although it is not yet clear to which extent these effects may be connected to the disease, especially once the consumption of tobacco and alcohol by these patients are taken into account. However, it has been argued that certain cannabinoids may have biological -anticancer- activities which could be used therapeutically without being accompanied by the corresponding 9-tetrahydrocannabinol psychoactive effects. It is well known that alcohol is a risk factor for developing head and neck cancer, and epidemiological studies indicate that the higher the consumption of alcohol, the more mortality due to cancer increases. In addition, it is suggested that there is no safety level for alcohol consumption regarding the risk of developing cancer; that is even a minimum daily consumption is associated with the occurrence of certain types of cancer

    The goal of this study was to describe the human figures portrayed in psychoactive drug advertising in terms of gender, age, ethnic group, and social context. Content analysis for 86 new pieces of printed advertisements released in 2005 was carried out. Fisher exact test was used to analyze the association between categories. There was a preponderance of women (62.8%) who were four times more present in advertisements for antidepressants and anxyolitics than men. Most of the people shown were Caucasian (98.8%) young adults (72%). These people were pictured in leisure activities (46.5%), at home (29%), or in contact with nature (16.2%). The message conveyed was that the drugs treat routinely felt subjective symptoms of discomfort, inducing in an irrational appeal that may affect drug prescription.

    Full Text Available Risk of substance dependence (SD and obesity has been linked to the function of melanocortin peptides encoded by the proopiomelanocortin gene (POMC.POMC exons were Sanger sequenced in 280 African Americans (AAs and 308 European Americans (EAs. Among them, 311 (167 AAs and 114 EAs were affected with substance (alcohol, cocaine, opioid and/or marijuana dependence and 277 (113 AAs and164 EAs were screened controls. We identified 23 variants, including two common polymorphisms (rs10654394 and rs1042571 and 21 rare variants; 12 of which were novel. We used logistic regression to analyze the association between the two common variants and SD or body mass index (BMI, with sex, age, and ancestry proportion as covariates. The common variant rs1042571 in the 3'UTR was significantly associated with BMI in EAs (Overweight: P(adj = 0.005; Obese: P(adj = 0.018; Overweight+Obese: P(adj = 0.002 but not in AAs. The common variant, rs10654394, was not associated with BMI and neither common variant was associated with SD in either population. To evaluate the association between the rare variants and SD or BMI, we collapsed rare variants and tested their prevalence using Fisher's exact test. In AAs, rare variants were nominally associated with SD overall and with specific SD traits (SD: P(FET,1df = 0.026; alcohol dependence: P(FET,1df = 0.027; cocaine dependence: P(FET,1df = 0.007; marijuana dependence: P(FET,1df = 0.050 (the P-value from cocaine dependence analysis survived Bonferroni correction. There was no such effect in EAs. Although the frequency of the rare variants did not differ significantly between the normal-weight group and the overweight or obese group in either population, certain rare exonic variants occurred only in overweight or obese subjects without SD.These findings suggest that POMC exonic variants may influence risk for both SD and elevated BMI, in a population-specific manner. However, common and rare variants in this gene may exert

    Researchers have consistently linked commercial sexual exploitation (CSE) of youth and involvement in prostitution with substance dependency and delinquency. Yet, important questions remain regarding the directionality and mechanisms driving this association. Utilizing a sample of 114 CSE/prostituted youth participating in the Pathways to Desistance study-a longitudinal investigation of the transition from adolescence to adulthood among serious adolescent offenders-the current study examined key criminal career parameters of CSE/prostitution including age of onset and rate of recurrence. Additionally, structural equation modeling (SEM) was used to explore concurrent associations and causal links between CSE/prostitution and drug involvement. Findings show a general sequential pattern of the ages of onset with substance use and selling drugs occurring prior to CSE/prostitution, evidence that a small group with chronic CSE/prostitution account for the majority of CSE/prostitution occurrences, and high rates of repeated CSE/prostitution. SEM results suggest CSE/prostituted youth persist in drug involvement from year to year but infrequently experience perpetuation of CSE/prostitution from year to year. Concurrent associations between CSE/prostitution and drug involvement were found across the length of the study. Additionally, drug involvement at one year was linked to CSE/prostitution during the subsequent year during early years of the study. © The Author(s) 2014.

    Nicotine Replacement Therapy (NRT) is recommended as a frontline smoking cessation tool for people attending mental health and substance dependence treatment services. Previous research suggests that NRT is underutilized in these settings. To improve the use of NRT amongst people attending residential treatment for substance use disorders (SUDs) it is important that the factors influencing smokers' decisions to use NRT are understood. The study aimed to examine: (1) smoking cessation strategies used by participants in previous quit attempts, (2) participants' attitudes towards NRT (i.e. safety concerns and perceived efficacy), and (3) the predictors of participants' intention to use NRT to support future quit attempts. Participants completed a cross-sectional survey that examined their smoking behaviours, previous experiences using smoking cessation strategies, attitudes and beliefs regarding NRT, and intention to use NRT as part of future quit attempts (N = 218). All participants were attending residential treatment for substance use disorders provided by We Help Ourselves (WHOS), a large provider of specialist alcohol and other drug treatment in Australia. The majority of respondents (98%) reported that they had smoked regularly in their lifetime, and 89% were current smokers. Forty-five percent of the current smokers reported that they had previously used NRT to support a quit attempt, with 54% reporting that they intended to use NRT to support a future quit attempt. Intentions to use NRT were not related to the participants' mental health status or the participants' perceptions regarding the safety or potential drawbacks associated with using NRT. However, participants were more likely to report that they would use NRT to support future quit attempts if they were female, had previously used NRT and perceived NRT to be effective. Improving the use of evidence based smoking cessation strategies within substance use treatment continues to be a priority. To enhance

    The design and implementation of a personality assessment system for severely substance-dependent men in a therapeutic community (TC) are described. The system was designed from a treatment utility perspective (Hayes, Nelson, & Jarrett, 1987) and uses the Personality Research Form E (Jackson, 1984) to provide each patient with feedback (a) describing his normal personality traits, (b) predicting his probable pattern of adjustment to the treatment setting, and (c) prescribing specific actions he can take to address potentially problematic behaviors. Discussing the the results with the patient helps him cope with the TC. Reviewing the assessment results with the staff promotes their empathy for the patient as a person whose behavior can be understood as an interaction of his personality with the specific demands of the TC rather than seeing the patient in exclusively pathological terms. Specific suggestions for behavior change guide both the patient and the staff and are potentially useful in various treatment settings.

    Aims The objective of this study was to examine the associations between compulsive buying (CB) and substance dependence/abuse, major depressive episode (MDE), and generalized anxiety disorder (GAD) at mean age 43. Methods Participants came from a community-based random sample of residents in two New York counties (N=548). The participants were followed from adolescence to early midlife. The mean age of participants at the most recent interview was 43.0 (SD=2.8). Fifty five percent of the participants were females. Over 90% of the participants were white. The prevalence of substance dependence/abuse, MDE, and GAD (during the past 5 years before the interviews) was 6.6%, 13.7, and 11.5%, respectively. Results Logistic regression analyses showed that CB was significantly associated with substance dependence/abuse [Adjusted Odds Ratio (A.O.R.) = 1.60], MDE (A.O.R. = 1.70), and GAD (A.O.R. = 1.63), despite controlling for substance dependence/abuse, MDE, and GAD, respectively, at mean age 37, and demographic factors. Discussion Since the study sample is limited to predominantly white participants (over 90%) with a close association to a small geographic area, the findings may not be generalizable to racial/ethnic minority groups or individuals living in other parts of the country. Nevertheless, it is important that clinicians treating substance dependence/abuse, MDE, and GAD consider the role of CB. PMID:27215919

    Although genetic risk factors have been found to contribute to dependence on both licit and illicit psychoactive substances, we know little of how these risk factors interrelate. To clarify the structure of genetic and environmental risk factors for symptoms of dependence on cannabis, cocaine, alcohol, caffeine, and nicotine in males and females. Lifetime history by structured clinical interview. General community. Four thousand eight hundred sixty-five members of male-male and female-female pairs from the Virginia Adult Twin Study of Psychiatric and Substance Use Disorders. Main Outcome Measure Lifetime symptoms of abuse of and dependence on cannabis, cocaine, alcohol, caffeine, and nicotine. Controlling for greater symptom prevalence in males, genetic and environmental parameters could be equated across sexes. Two models explained the data well. The best-fit exploratory model contained 2 genetic factors and 1 individual environmental factor contributing to all substances. The first genetic factor loaded strongly on cocaine and cannabis dependence; the second, on alcohol and nicotine dependence. Nicotine and caffeine had high substance-specific genetic effects. A confirmatory model, which also fit well, contained 1 illicit drug genetic factor--loading only on cannabis and cocaine--and 1 licit drug genetic factor loading on alcohol, caffeine, and nicotine. However, these factors were highly intercorrelated (r = + 0.82). Large substance-specific genetic effects remained for nicotine and caffeine. The pattern of genetic and environmental risk factors for psychoactive substance dependence was similar in males and females. Genetic risk factors for dependence on common psychoactive substances cannot be explained by a single factor. Rather, 2 genetic factors-one predisposing largely to illicit drug dependence, the other primarily to licit drug dependence-are needed. Furthermore, a large proportion of the genetic influences on nicotine and particularly caffeine dependence

    The current study examined the association among family history of substance use problems, childhood maltreatment, and age of first drug use in a sample of men and women seeking treatment for methamphetamine dependence. Various forms of childhood maltreatment were considered as mediators of the association between family history of substance use problems and age of first drug use. Participants (N = 99, 40% women, mean age 33) who were under treatment for methamphetamine dependence completed a baseline interview that obtained demographic information, past substance use by participants, history of drug/alcohol problems in their family of origin, and age at first use of any drug (excluding alcohol and tobacco). The Early Trauma Inventory Self-Report-Short Form was used to assess child maltreatment experiences before the age of 18. Family history of substance use problems and childhood physical (but not emotional or sexual) trauma significantly predicted age of first drug use. Further, childhood physical trauma mediated the association between family history of substance use problems and age of first drug use. These findings suggest that the experience of childhood physical abuse may be an important mechanism through which family history of substance use is associated with an earlier age of first drug use.

    The present study aims to examine the role of emotion dysregulation and childhood maltreatment in self mutilation (SM) of substance dependent patients. Specifically, the present study examined whether emotion dysregulation and its dimensions, and childhood maltreatment and its dimensions were associated with SM. The relationship between emotion dysregulation and childhood maltreatment was also investigated. The sample of study consisted of 55 alcohol dependent and 24 opiate dependent patients (n=79). Substance dependence was diagnosed by means of the Structured Clinical Interview for DSM-IV-TR (SCID-I), Turkish version. Childhood Trauma Questionnaire (CTQ) and Difficulties in Emotion Regulation Scale (DERS) were used. Findings indicated that substance dependents with SM and without SM were differentiated in terms of overall emotion dysregulation. Results also suggest the relevance of three specific dimensions of emotion dysregulation to SM: Difficulties engaging in goal-directed behaviors when experiencing negative emotions, difficulties controlling impulsive behaviors when experiencing negative emotions, and limited access to effective emotion regulation strategies. These dimensions were predicted from childhood emotional maltreatment and neglect. It is also revealed that substance dependents with SM had higher points than those without SM on emotional childhood maltreatment and neglect, physical childhood maltreatment. Results were supported by the literature suggested that self-mutilation functions as a emotional regulation strategy. Findings also suggested that self- mutilation is related to early relationships take place in family environment in which individuals grow up.

    Full Text Available The emergence of risky behavior is characteristic in adolescence. Of all forms of risky behavior in adolescence, the use of psychoactive substances - cigarettes, alcohol and illegal psychoactive substances particularly stand out, because of the frequency and degree of prevalence of use, and because of the impact that they have on youth development in this sensitive stage of growing up. Unfortunately, today we are witnessing the fact that such behavior in adolescents has gained an increasingly epidemic character mainly due to the characteristics of the social context in which young people are growing up. The main objective of this research, conducted in the framework of the doctoral dissertation of the author, was determining relations between relevant sociodemographic factors: gender, age, school success, financial status and place of residence of respondents, with the appearance and intensity of use of three types of psychoactive substances - cigarettes, alcohol and illegal psychoactive substances among the general population of adolescents. The sample represents non-clinical young population, and it consists of 529 adolescents, students of the 2nd and 4th class of secondary school (17 and 18 years old. The data was collected by using Scale use of PAS (psychoactive substances in adolescents, which was designed for the purpose of this research, as well as using a set of questions intended for the registration of socio-demographic variables. Respondents filled in questionnaires in groups, during the school lessons. The data show a relationship between the three studied socio-demographic variables with the occurrence and degree of use of psychoactive substances in the adolescence period, such as gender, age and school success of the respondents. As regards gender of respondents associated with the occurrence and degree of alcohol and illegal substance use in adolescents, male adolescents more likely use alcohol and illegal psychoactive substances

    Injecting drug user size estimation studies carried out in 2009, 2012 and 2015 revealed growing trends of drug abuse in Georgia:estimated number of people who inject drugs (PWID) have been increased from 40000 and 45000 to 50000. Since Soviet period the most popular injective narcotics have been opioids: home-made opium, heroine, buprenorphine and home-made desomorphine ("Krokodile") replacing each other on the black market. Self-made desomorphine typically contains big amounts of different toxic substances and causes significant somatic disorders, especially skin, bone, blood infections, liver and kidney failure; is highly addictive, associates with frequent injections that enhance injecting-related harm, including the risk of HIV transmission, in comparison with typical opioids. The aim of the study was to determine the effectiveness of opioid substitution treatment (OST) on depression and anxiety in opioid dependent clients with history of different opioid substance use. 104 opioid drug users undergoing OST with intensive psychological counseling have been divided in 5 groups according to the principal opioid drug that was abused during past 6 months before starting treatment: heroine, desomorphine, illicit methadone injectors, illicit buprenorphine injectors, and multiple drug abusers consuming opioids as primary drugs. Level of depression (Beck Depression Inventory), anxiety (Spielberger Anxiety Inventory) as well as clinical symptoms, risky behavior, quality of life (WHO), and other data were measured before starting and after 3, 9, 15, 21 months of treatment. The illegal use of psychotropic-narcotics was checked through random urine-testing 1-2 times per patient per month. In all five groups remarkable decrease of depression and anxiety was observed in comparison with the starting data. Before inclusion desomorphine and poly-drug users had the highest scores of depression and anxiety while buprenorphine users manifested the lowest rate. Improvement of

    Prenatal exposures to alcohol, cigarettes, and other drugs of abuse are associated with numerous adverse consequences for affected offspring, including increased risk for substance use and abuse. However, maternal substance use during pregnancy appears to occur more often in those with a family history of alcohol dependence. Utilizing a sample that is enriched for familial alcohol dependence and includes controls selected for virtual absence of familial alcohol dependence could provide important information on the relative contribution of familial risk and prenatal exposures to offspring substance use. A sample of multigenerational families specifically ascertained to be at either high or low risk for developing alcohol dependence (AD) provided biological offspring for a longitudinal prospective study. High-risk families were selected based on the presence of 2 alcohol-dependent sisters. Low-risk families were selected on the basis of minimal first and second-degree relatives with AD. High-risk (HR = 99) and Low-risk offspring (LR = 110) were assessed annually during childhood and biennially in young adulthood regarding their alcohol, drug, and cigarette use. At the first childhood visit, mothers were interviewed concerning their prenatal use of substances. High-risk mothers were more likely to use alcohol, cigarettes, and other drugs during pregnancy than low-risk control mothers, and to consume these substances in greater quantities. Across the sample, prenatal exposure to alcohol was associated with increased risk for both offspring cigarette use and substance use disorders (SUD), and prenatal cigarette exposure was associated with increased risk for offspring cigarette use. Controlling for risk status by examining patterns within the HR sample, prenatal cigarette exposure remained a specific predictor of offspring cigarette use, and prenatal alcohol exposure was specifically associated with increased risk for offspring SUD. Women with a family history of

    To explore the relationship between occurrence of drug dreams (DDs) and daytime negative affect and drug craving during the course of a 5-week treatment program for substance dependence. Using the dream journal methodology, 86 participants reported occurrence of dreams, dream content, and ratings of affect and drug craving. The relationships between the experience of DD, dream content ("active" vs "passive"), and affect and craving were analyzed using mixed model methods. The experience of DD was associated with higher levels of negative affect (P < 0.001) and craving (P < 0.001). The occurrence of DD did not decrease significantly over the 5 weeks of the study. Cocaine/crack users reported a higher occurrence of DD (P < 0.05) than the other drug groups (opiates and alcohol), and DD involving "active" drug use was associated with larger (P < 0.05) changes in negative affect. These results are consistent with the hypothesis that DD can act as drug-conditioned stimuli to elevate negative affect and craving in abstaining individuals. Although correlational, such findings support the implementation of psychological and pharmacological interventions aimed at minimizing the impact of DD on individuals in recovery from drug addiction.

    Substance dependence and antisocial psychopathology, such as a history of childhood conduct disorder (HCCD), are associated with impulsive or disadvantageous decision making and reduced working memory capacity (WMC). Reducing WMC via a working memory load increases disadvantageous decision making in healthy adults, but no previous studies have examined this effect in young adults with substance dependence and HCCD. Young adults with substance dependence (SubDep; n=158, 71 female), substance dependence and HCCD (SubDep+HCCD; n=72, 24 female), and control participants (n=152, 84 female) completed a test of decision making (the Iowa Gambling Task; IGT) with or without a concurrent working memory load intended to tax WMC. Outcomes were (i) net advantageous decisions on the IGT, and (ii) preferences for infrequent- versus frequent-punishment decks. SubDep+HCCD men made fewer advantageous decisions on the IGT than control men without a load, but there were no group differences among women in that condition. Load was associated with fewer advantageous decisions for SubDep+HCCD women and control men, but not for men or women in the other groups. Participants showed greater preference for infrequent-punishment, advantageous decks under load as well. There are gender differences in the effects of substance dependence, HCCD, and working memory load on decision making on the IGT. Decision making by control men and SubDep+HCCD women suffered the most under load. Load increases preferences for less-frequent punishments, similar to a delay discounting effect. Future research should clarify the cognitive and neural mechanisms underlying these effects. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    The objective of this study was to examine the associations between compulsive buying and substance dependence/abuse, major depressive episodes, and generalized anxiety disorder at the mean age of 43. Participants came from a community-based random sample of residents in 2 New York counties in 1975 (N = 548). The participants were followed from adolescence to early midlife. The mean age of participants at the most recent interview was 43.0 (standard deviation = 2.8). Of the participants, 55% were females. Over 90% of the participants were Caucasian. The prevalence of substance dependence/abuse, major depressive episodes, and generalized anxiety disorder (during the past 5 years before the interviews) was 6.6, 13.7, and 11.5%, respectively. Logistic regression analyses showed that compulsive buying was significantly associated with substance dependence/abuse (adjusted odds ratio = 1.60), major depressive episodes (adjusted odds ratio = 1.70), and generalized anxiety disorder (adjusted odds ratio = 1.63), despite controlling for substance dependence/abuse, major depressive episodes, and generalized anxiety disorder, respectively, at the mean age of 37, and demographic factors. Since the study sample is limited to predominantly Caucasian participants (over 90%) with a close association to a small geographic area, the findings may not be generalizable to racial/ethnic minority groups or individuals living in other parts of the country. Nevertheless, it is important that clinicians treating substance dependence/abuse, major depressive episodes, and generalized anxiety disorder consider the role of compulsive buying.

    The aim of this study was to investigate factors associated to psychoactive medication use and dependence in working environment during a 1-year period. We performed a 1-year-follow-up cohort study including workers from Toulouse metropolitan area. During their annual compulsory examination to assess their aptitude to work, subjects were asked to fill in an anonymous questionnaire at 1 year interval, in May 2000 and May-June 2001. Among a study sample of 1273 subjects (47.4% of men, mean age 39.2 +/- 9.2 years), the prevalence of psychoactive medication use at baseline was 9.1% (4.3% anxiolytic, 1.9% hypnotic, 1.7% antidepressant, 2.1% opiate analgesic and 0.5% antipsychotic drugs, according to ATC classification). Dependence on these drugs was found in 3.5% of workers. This consumption was associated with professional categories (higher in employees versus senior executive, Odds Ratio: 1.80; 95% Confidence Interval [1.04-3.11]), low job satisfaction and outside workplace (1.92; [1.30-2.84] and 3.40; [2.27-5.09] respectively), and patterns of medication use at workplace: for sleeping disorders related to job (18.27; [11.81-28.26]), for enhancing performance at work (28.13; [12.00-65.92]), for relieving unpleasant symptoms at work (22.98; [9.59-55.01]). The risk of psychoactive medication chronic use (psychoactive drug users in 2000 and 2001), and dependence at 1 year were both strongly associated with nicotine dependence (5.99 and 6.23, respectively) and performance-enhancing behaviour with drugs and/or alcohol (8.35 and 3.32 respectively), whereas current use (psychoactive drug users only in 2001) was strongly associated with performance-enhancing behaviour. Among workers using psychoactive drugs, one out of three are dependent on psychoactive medications. Performance-enhancing behaviour and coping strategies might be a determinant of psychoactive drug use and could lead to dependence in the workplace.

    New psychoactive substances (NPS) are an increasing problem in clinical and forensic toxicology. The knowledge of their metabolism is important for toxicological risk assessment and for developing toxicological urine screenings. Considering the huge numbers of NPS annually appearing on the market, metabolism studies should be realized in a fast, simple, cost efficient, and reliable way. Primary human hepatocytes (PHH) were recommended to be the gold standard for in vitro metabolism studies as they are expected to contain natural enzyme clusters, co-substrates, and drug transporters. In addition, they were already successfully used for metabolism studies of NPS. However, they also have disadvantages such as high costs and limited applicability without special equipment. The aims of the present study were therefore first to investigate exemplarily the phase I and phase II metabolism of six NPS (XLR-11, AB-PINACA, FUB-PB-22, 4-methoxy-α-PVP, 25-I-NBOMe, and meclonazepam) from different drug classes using pooled human S9 fraction (pS9) or pooled human liver microsomes combined with cytosol (pHLM/pHLC) after addition of the co-substrates for the main metabolic phase I and II reactions. Second to compare results to published data generated using primary human hepatocytes and human urine samples. Results of the incubations with pS9 or pHLM/pHLC were comparable in number and abundance of metabolites. Formation of metabolites, particularly after multi-step reactions needed a longer incubation time. However, incubations using human liver preparations resulted in a lower number of total detected metabolites compared to PHH, but they were still able to allow the identification of the main human urinary excretion products. Human liver preparations and particularly the pooled S9 fraction could be shown to be a sufficient and more cost-efficient alternative in context of metabolism studies also for developing toxicological urine screenings. It might be recommended to use the

  5. Decision-Making and the Iowa Gambling Task: Ecological validity in individuals with substance dependence

    Full Text Available Substance Dependent Individuals (SDIs usually show deficits in real-life decision-making, as illustrated by their persistence in drug use despite a rise in undesirable consequences. The Iowa Gambling Task (IGT is an instrument that factors a number of aspects of real-life decision-making. Although most SDIs are impaired on the IGT, there is a subgroup of them who perform normally on this task. One possible explanation for this differential performance is that impairment in decision-making is largely detected on the IGT when the use of drugs escalates in the face of rising adverse consequences. The aim of this study is to test this hypothesis, by examining if several real-life indices associated with escalation of addiction severity (as measured by the Addiction Severity Index -ASI- are predictive of risky decisions, as revealed by impaired performance on different versions of the IGT. We administered the ASI and different versions of the IGT (the main IGT version, a variant IGT version, and two parallel versions of each to a large sample of SDI. We used regression models to examine the predictive effects of the seven real-life domains assessed by the ASI on decision-making performance as measured by the IGT. We included in regression models both ASI-derived objective and subjective measures of each problem domain. Results showed (i that several aspects of real-life functioning associated with addiction severity were moderate predictors of IGT decision-making performance; (ii that the combined assessment of decision-making using different versions of the IGT yielded better predictive measures than assessment using isolated versions of the IGT; and (iii that objective measures of real-life functioning were better predictors of decision-making performance on the IGT than subjective measures based on SDI's insight about their problems. These results support the notion that decision-making deficits as measured by the IGT are associated with a rise in

    A sizable segment of addiction research investigates the effects of persuasive message appeals on risky and deleterious behaviors. However, to date, little research has examined how various forms of message framing and corresponding behavioral choices might by mediated by risk-related brain regions. Using event-related functional magnetic resonance imaging, we investigated brain regions hypothesized to mediate the influence of message appeals on decision making in substance-dependent (SD) compared to non-substance-dependent (non-SD) individuals. The Iowa Gambling Task (IGT) was modified to include positively-framed, negatively-framed, and control messages about long-term deck payoffs. In the positively-framed condition, the SD and non-SD groups showed improved decision-making performance that corresponded to higher risk-aversion-related brain activity in the anterior cingulate cortex (ACC) and anterior insula (AI). In contrast, in the negatively-framed condition, the SD group showed poorer performance that corresponded to lower risk-aversion-related brain activity in the AI region. In addition, only the non-SD group showed a positive association between decision quality and greater risk-related activity in the ACC, regardless of message type. The findings suggest substance-dependent individuals may have reduced neurocognitive sensitivity in the ACC and AI regions involved in risk perception and aversion during decision-making, especially in response to framed messages that emphasize reduced prospects for long-term gains.

    High levels of childhood traumatic experiences have been observed among substance abusers. There has been insufficient study of the effects of childhood trauma in adulthood. The aim of this study is to research the relationship between childhood trauma, self-esteem, and levels of depression and anxiety in substance-dependent (SD) people. This study took place between March 2012 and April 2013, at Balıklı Rum Hospital (Istanbul) substance dependency clinic. It included 50 patients diagnosed as substance dependent according to the criteria of DSM-IV as compared with 45 healthy controls. The Structured Clinical Interview for DSM-IV Diagnosis (SCID-I) was used to identify Axis I disorders. All other data was collected using a semi-structured socio-demographic questionnaire, the Childhood Trauma Questionnaire (CTQ), the Rosenberg Self Esteem Scale (RSES), the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). The total scores of the SD group on the CTQ and on its Emotional Abuse/Emotional Neglect (EA/EN), Physical Abuse (PA) and Sexual Abuse (SA) subscales were statistically significant. In relation to the healthy controls, the SD group scored higher on the RSES, BDI and BAI. A correlation was observed between the total scores of SD individuals on the CTQ and their scores on the RSES, BDI and BAI. This study showed high levels of childhood traumatic experiences for SD people and indicates that there may be a relationship between these experiences and their levels of self-esteem, depression and anxiety.

    Full Text Available Abstract Background RGS17 and RGS20 encode two members of the regulator of G-protein signaling RGS-Rz subfamily. Variation in these genes may alter their transcription and thereby influence the function of G protein-coupled receptors, including opioid receptors, and modify risk for substance dependence. Methods The association of 13 RGS17 and eight RGS20 tag single nucleotide polymorphisms (SNPs was examined with four substance dependence diagnoses (alcohol (AD, cocaine (CD, opioid (OD or marijuana (MjD] in 1,905 African Americans (AAs: 1,562 cases and 343 controls and 1,332 European Americans (EAs: 981 cases and 351 controls. Analyses were performed using both χ2 tests and logistic regression analyses that covaried sex, age, and ancestry proportion. Correlation of genotypes and mRNA expression levels was assessed by linear regression analyses. Results Seven RGS17 SNPs showed a significant association with at least one of the four dependence traits after a permutation-based correction for multiple testing (0.003≤Pempirical≤0.037. The G allele of SNP rs596359, in the RGS17 promoter region, was associated with AD, CD, OD, or MjD in both populations (0.005≤Pempirical≤0.019. This allele was also associated with significantly lower mRNA expression levels of RGS17 in YRI subjects (P = 0.002 and non-significantly lower mRNA expression levels of RGS17 in CEU subjects (P = 0.185. No RGS20 SNPs were associated with any of the four dependence traits in either population. Conclusions This study demonstrated that variation in RGS17 was associated with risk for substance dependence diagnoses in both AA and EA populations.

    Although child neglect and substance abuse co-occur in greater than 60% of child protective service cases, intervention outcome studies are deplorably lacking. Therefore, a home-based Family Behavior Therapy is described in the treatment of a woman evidencing child neglect, substance dependence, domestic violence and other co-occurring problems. Treatment included contingency management, self control, stimulus control, communication and child management skills training exercises, and financial management components. Results indicated improvements in child abuse potential, home hazards, domestic violence, and drug use, which were substantiated by objective urinalysis testing, and tours of her home. Validity checks indicated the participant was being truthful in her responses to standardized questionnaires, and assessors were “blind” to study intent. Limitations (i.e., lack of experimental control and follow-up data collection) of this case example are discussed in light of these results. PMID:23226920

    Objective Neurocognitive impairment has not consistently predicted substance use treatment outcomes but has been linked to proximal mediators of outcome. These indirect effects have not been examined in adults with substance dependence and co-occurring psychiatric disorders. We examined mediators and moderators of the effects of neurocognitive impairment on substance use among adults in treatment for alcohol or drug dependence and major depression (MDD). Method Participants were veterans (N =197, mean age = 49.3 years, 90% male, 75% Caucasian) in a trial of two group interventions for alcohol/drug dependence and MDD. Measures examined here included intake neurocognitive assessments and percent days drinking (PDD), percent days using drugs (PDDRG), self-efficacy, 12-step affiliation, and depressive symptoms measured every 3 months from intake to the 18-month follow-up. Results Greater intake neurocognitive impairment predicted lower self-efficacy, lower 12-step affiliation, and greater depression severity, and these time-varying variables mediated the effects of impairment on future PDD and PDDRG. The prospective effects of 12-step affiliation on future PDD were greater for those with greater neurocognitive impairment. Impairment also interacted with depression to moderate the effects of 12-step affiliation and self-efficacy on PDD. Adults with greater impairment and currently severe depression had the strongest associations between 12-step affiliation/self-efficacy and future drinking. Conclusions Greater neurocognitive impairment may lead to poorer outcomes from group therapy for alcohol/drug dependence and MDD due to compromised change in therapeutic processes. Distal factors such as neurocognitive impairment can interact with dynamic risk factors to modulate the association between therapeutic processes and future drinking outcomes. PMID:24588403

    We estimate the prevalence of alcohol, tobacco and illegal substance use in a national representative sample of adolescents. We also estimate how socio demographic characteristics, household environment and mental health are associated with substance misuse. This is a cross-sectional study using data from the first Brazilian National Alcohol Survey, which gathered information on the use of psychoactive substances in 761 participants aged 14 to 19 years old. Weighted logistic regression was used to calculate adjusted odds ratios. More than half of the adolescents interviewed were regular alcohol users and one out of ten were abusers and/or dependents. Older male adolescents living in urban areas were more likely to present alcohol related disorders and to smoke. Age had an inverse association with illegal substance use. Smokers and those using illegal substances were more likely to report domestic violence while those with alcohol abuse/dependence were more likely to have depression. The high prevalence of alcohol, tobacco and illicit substance consumption among Brazilian adolescents is staggering. Young males with mood disorders from urban areas are more at risk of developing alcohol disorders while illegal drug use is highly associated to household dysfunction in early life. Brazilian growing economy will possibly lead to increased levels of substance use among adolescents if new prevention measures are not implemented. The intensification of law enforcement strategies to reduce psychotropic substances access is required. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background A lot of studies were directed to explore the relation between drug abuse and neuropsychological functions. Some studies reported that even after a long duration of disappearance of withdrawal or intoxication symptoms, many patients have obvious deterioration of cognitive functions. The aim of this study was to explore the relationship between the substance use disorders and the executive functions. Methods Two groups were selected for this study. An experimental group consisted of 154 patients and further subdivided according to the substance used into three different subgroups: opioid, amphetamine and alcohol groups which included 49, 56 and 49 patients respectively. The control group was selected matching the experimental group in the demographic characteristics and included 100 healthy persons. Tools used were: Benton visual retention tests, color trail making test, Stroop colors-word test, symbol digit modalities test, the five dots cognitive flexibility test, and TAM verbal flexibility test. All the data were subjected to statistical analysis Results The study showed that the group of drug-dependent subjects performed significantly worse than the comparison group on all measures Also, there were significant differences among the subgroups as the alcoholic group was much worse followed by the amphetamine then the opioids groups. Patients with longer duration of dependence and multiple hospital readmissions were much worse in comparison to patients with shorter duration of dependence and less readmission. Conclusion The study confirmed that the functions of specific brain regions underlying cognitive control are significantly impaired in patients of drug addiction. This impairment was significantly related to type of substance, duration of use and number of hospitalization and may contribute to most of behavioral disturbances found in addicts and need much attention during tailoring of treatment programs.

    One-hundred-thirty-one homeless, substance-dependent MSM were enrolled in a randomized controlled trial to assess the efficacy of a contingency management (CM) intervention for reducing substance use and increasing healthy behavior. Participants were randomized into conditions that either provided additional rewards for substance abstinence and/or health-promoting/prosocial behaviors ("CM-full"; n=64) or for study compliance and attendance only ("CM-lite"; n=67). The purpose of this secondary analysis was to determine the affect of ASPD status on two primary study outcomes: methamphetamine abstinence, and engagement in prosocial/health-promoting behavior. Analyses revealed that individuals with ASPD provided more methamphetamine-negative urine samples (37.5%) than participants without ASPD (30.6%). When controlling for participant sociodemographics and condition assignment, the magnitude of this predicted difference increases to 10% and reached statistical significance (p<.05). On average, participants with ASPD earned fewer vouchers for health-promoting/prosocial behaviors than participants without ASPD ($10.21 [SD=$7.02] versus $18.38 [SD=$13.60]; p<.01). Participants with ASPD displayed superior methamphetamine abstinence outcomes regardless of CM schedule; even with potentially unlimited positive reinforcement, individuals with ASPD displayed suboptimal outcomes in achieving health-promoting/prosocial behaviors.

    A sizable segment of addiction research investigates the effects of persuasive message appeals on risky and deleterious behaviors. However, to date, little research has examined how various forms of message framing and corresponding behavioral choices might by mediated by risk-related brain regions. Using event-related functional MRI, we investigated brain regions hypothesized to mediate the influence of message appeals on decision making in substance-dependent (SD) compared with nonsubstance-dependent (non-SD) individuals. The Iowa Gambling Task (IGT) was modified to include positively-framed, negatively-framed, and control messages about long-term deck payoffs. In the positively-framed condition, the SD and non-SD groups showed improved decision-making performance that corresponded to higher risk-aversion-related brain activity in the anterior cingulate cortex (ACC) and anterior insula (AI). In contrast, in the negatively-framed condition, the SD group showed poorer performance that corresponded to lower risk-aversion-related brain activity in the AI region. In addition, only the non-SD group showed a positive association between decision quality and greater risk-related activity in the ACC, regardless of message type. The findings suggest substance-dependent individuals may have reduced neurocognitive sensitivity in the ACC and AI regions involved in risk perception and aversion during decision-making, especially in response to framed messages that emphasize reduced prospects for long-term gains.

    People with addictive disorders commonly do not receive efficacious medications. Chronic care management (CCM) is designed to facilitate delivery of effective therapies. Using data from the CCM group in a trial testing its effectiveness for addiction (n=282), we examined factors associated with the prescription of addiction medications. Among participants with alcohol dependence, 17% (95%CI 12.0–22.1%) were prescribed alcohol dependence medications. Among those with drug dependence, 9% (95%CI 5.5–12.6%) were prescribed drug dependence medications. Among those with opioids as a substance of choice, 15% (95%CI 9.3–20.9%) were prescribed opioid agonist therapy. In contrast, psychiatric medications were prescribed to 64% (95%CI 58.2–69.4%). Absence of co-morbid drug dependence was associated with prescription of alcohol dependence medications. Lower alcohol addiction severity and recent opioid use were associated with prescription of drug dependence medications. Better understanding of infrequent prescription of addiction medications, despite a supportive clinical setting, might inform optimal approaches to delivering addiction medications. PMID:25524751

    The aims of this study were to estimate the prevalence and predictors of non-medical substance use, and to assess the association between non-medical substance use and fatal poisoning or history of drug abuse in Finland. Retrospective cohort study of all medico-legally investigated death cases in Finland. The postmortem toxicology database was linked together with the register on reimbursed prescription medicines. All postmortem cases between 2011 and 2013 positive for one or more of the following drugs: oxycodone, fentanyl, tramadol, clonazepam, gabapentin, pregabalin, tizanidine, olanzapine, quetiapine, risperidone, alprazolam, zolpidem, mirtazapine and bupropion, n = 2974. Non-medical use of substance was the outcome variable. Predictors were the following: gender, residence at the time of death, place of death, blood alcohol concentration, age, drug abuse, number of prescriptions of any psychoactive drugs in last year and proportion of prescriptions issued by psychiatrist in last year. In 50.4% of the studied cases, at least one drug was detected without a prescription. Clonazepam, alprazolam and tramadol were the most prevalent non-medical findings in these cases (6.6, 6.1 and 5.6%, respectively). The risk of non-medical use of prescription drugs was especially high in cases with history of drug abuse (88.5%) and in fatal poisonings (71.0%). The proportion of non-medical use of the studied substances varied between 5.9% [95% confidence interval (CI) = 3.1-10.1%)] for risperidone and 55.7% for fentanyl (95% CI = 44.1-66.9%). Valid prescription for one or more of any psychoactive drug was associated with lower odds for non-medical use of the studied substances. Additionally, the higher the proportion of psychoactive drugs prescribed by a psychiatrist, the lower the probability of non-medical use. Non-prescribed psychoactive drugs are found commonly at postmortem in drug poisoning deaths in Finland, with history of drug abuse being a major contributing

  20. Microbial utilization of low molecular weight organics in soil depends on the substances properties

    Utilization of low molecular weight organic substances (LMWOS) in soil is regulated by microbial uptake from solution and following incorporation of into specific cell cycles. Various chemical properties of LMWOS, namely oxidation state, number of carbon (C) atoms, number of carboxylic (-COOH) groups, can affect their uptake from soil solution and further microbial utilization. The aim of the study was to trace the initial fate (including the uptake from soil solution and utilization by microorganisms) of three main classes of LMWOS, having contrast properties - sugars, carboxylic and amino acids. Top 10 cm of mineral soil were collected under Silver birch stands within the Bangor DIVERSE experiment, UK. Soil solution was extracted by centrifugation at 4000 rpm during 15 min. Soil was spiked with 14C glucose or fructose; malic, succinic or formic acids; alanine or glycine. No additional non-labeled LMWOS were added. 14C was traced in the dissolved organic matter (DOM), CO2, cytosol and soil organic matter (SOM) during one day. To estimate half-life times (T1 /2)of LMWOS in soil solution and in SOM pools, the single and double first order kinetic equations were fitted to the uptake and mineralization dynamics, respectively. The LMWOS T1 /2in DOM pool varied between 0.6-5 min, with the highest T1 /2for sugars (3.7 min) and the lowest for carboxylic acids (0.6-1.4 min). Thus, initial uptake of LMWOS is not a limiting step of microbial utilization. The T1 /2 of carboxylic and amino acids in DOM were closely related with oxidation state, showing that reduced substances remain in soil solution longer, than oxidized. The initial T1 /2 of LMWOS in SOM ranged between 30-80 min, with the longest T1 /2 for amino acids (50-80 min) and the shortest for carboxylic acids (30-48 min). These T1 /2values were in one-two orders of magnitude higher than LMWOS T1 /2 in soil solution, pointing that LMWOS mineralization occur with a delay after the uptake.

    We present a case of a fatal toxic leukoencephalopathy following ingestion of a new psychoactive designer drug known as 2C-E or "Europa." Recreational drugs, particularly hallucinogenic substances, appear to be growing in popularity, with increasing amounts of information available via the Internet to entice potential users. In addition, some newer "designer" psychoactive substances are available for purchase online without adverse legal consequences, therefore adding to their popularity. We describe magnetic resonance imaging (MRI) findings to include selective diffuse toxic injury of the cerebral white matter with sparing of the cortex and most of the deep gray nuclei. To our knowledge, this is the first reported description of cerebral findings on MRI that are likely related to a lethal ingestion of 2C-E.

This exploratory study assessed the relationships between patient and physician characteristics and early outpatient satisfaction with care for alcohol and opioid dependence. Methods: Satisfaction was assessed using a multidimensional, self-administered and validated questionnaire during the early care process among a prospective outpatient cohort. In addition to measuring satisfaction and obtaining sociodemographic and clinical data, this study collected data on the self-reported health status and physician characteristics at inclusion. Cross-sectional analysis with multiple linear regression was performed to identify the variables associated with satisfaction level. Results: A total of 249 outpatients were included, and 63.8% completed the satisfaction questionnaire. Patients without a history of previous care for substance dependence were more satisfied with the appointment-making process (β=7.2; P=0.029 and with the doctor consultation (β=10.3; P=0.003 than those who had received care previously. Neither sociodemographic characteristics nor self-reported health status was associated with outpatient satisfaction. Conclusion: The factors that affect patients

    Research in adults shows that substance dependent individuals demonstrate attentional bias (AB) for substance-related stimuli. This study investigated the role of AB in adolescents diagnosed with alcohol, cannabis, amphetamine or GHB dependency on entering therapy and six months later, and the role of executive control (EC) as a moderator of the relationship between problem severity and AB. Seventy-eight young substance-dependent (SD) patients (mean age=19.5), and 64 healthy controls (HC; mean age=19.0) were tested. Thirty-eight SD patients took part at 6-month follow-up (FU). AB was indexed by a visual probe task, EC by the attention network task, problem severity by the short alcohol (or drug) use disorder identification test and the severity of dependence questionnaire. SD patients demonstrated an AB for substance stimuli presented for 500 ms and 1250 ms, with the latter related to severity of dependence. There was a nonsignificant tendency indicating that EC was higher in HC than SD participants, but EC did not moderate the relationship between AB and dependency. Substance use, dependency, EC and AB remained unchanged in the 6 month FU period. Young SD patients showed a stronger relatively early as well as maintained AB toward substance cues. A stronger maintained attention was related to higher severity of dependence. Further, there were some indications that EC might play a role in adolescent substance use. The finding that at FU AB and problem severity were not decreased, and EC was not increased underlines the persistent character of addiction. Copyright © 2015 Elsevier Ireland Ltd.

    frequency of risk and protection factors related to drug consumption among undergraduate nursing students. It is a cross-sectional study in which authors applied the instrument Risk and Protection Factors for the Consumption of Psychoactive Substances, validated for use with undergraduate nursing students. Data were analyzed through STATA 10. Three hundred and ninety students participated in the study. The domain "prejudice and appraisal", "social permissiveness and access to psychoactive substances", "social skills and self-control" are risk factors for drugs use in 100% of participants. "Spirituality" and "satisfaction with interpersonal relations" were predominant protective domains. Based on data, authors can conclude that the students did not consider the risks in alcohol and tobacco consumption, as they think it is normal and socially acceptable.

  7. EMOTIONALLY AVOIDANT LANGUAGE IN THE PARENTING INTERVIEWS OF SUBSTANCE-DEPENDENT MOTHERS: ASSOCIATIONS WITH REFLECTIVE FUNCTIONING, RECENT SUBSTANCE USE, AND PARENTING BEHAVIOR

    2012-01-01

    Parenting and emotion regulation are two known, and potentially interrelated, areas of impairment among substance-abusing mothers. In this study, we examine substance -abusing mothers’ (positive and negative) emotion language word use during their discussion of negative parenting experiences on the Parent Development Interview for its association with reflective functioning (RF), recent substance-use history, and sensitivity to child cues. Within a sample of 47 methadone-maintained mothers, we evaluate the hypothesis that linguistic evidence of emotional avoidance (more frequent positive feeling words and less frequent negative emotion words) will be associated with lower RF, more recent substance use, and more insensitive parenting. Further, we evaluate whether language use mediates the association between self-focused RF and insensitive parenting. Results of hierarchical regressions suggest that more frequent positive feeling word use, but not negative emotion word use, is associated with lower RF, more recent substance use, and lower sensitivity to child cues. Positive feeling word use partially mediates the association between self-focused RF and insensitive parenting. Results are discussed in the context of their contribution to the literature on emotion and parenting in substance-abusing populations. PMID:23049148

    Full Text Available Objective: In this study, it is aimed to evaluate the validity and reliability of the Beliefs About Substance Use Questionnaire (BSU which was originally developed by Wright (1993. Method: Seventy alcohol addicted inpatients, who were admitted to Ankara Dışkapı Yıldırım Beyazıt Education and Research Hospital Psychiatry Clinic, 31 healthy volunteers who had never used alcohol and 33 social drinkers were evaluated. For all groups, BSU and Craving Beliefs Questionnaire (CBQ, for the patient groups, Beck Anxiety Inventory (BAI, Clinical Institute Withdrawal Assessment (CIWA, Dysfunctional Attitudes Questionnaire (DAS and Automatic Thoughts Questionnaire (ATQ were used as the assessment tools. The correlations and differences between the questionnaires were studied. Results: Mean age of the addicted patients, healthy controls and social drinkers were 42,3± 7,0, 33,5± 9,9 and 33,2± 8,9, respectively. In patient group, mean BSU score was 46,4 ± 21,2. For alcohol addicts, internal reliability of BSU was found to be adequate (Cronbach alfa=0.91 and item-total score correlations were between 0.33 and 0.69. Basic component analysis showed one basic factor. A positive correlation has been found between BSU and CBQ, and ATQ scores. No correlations have been found between total and subscale scores of DAS and total scores of CIWA, BAI and BSU. In evaluation of validity, BSU mean scores of alcohol addicts were found to be significantly higher than healthy controls and social drinkers. Conclusion: Our findings support that Turkish version of BSU is an adequate tool that can be used to evaluate alcohol addicted patients` cognitive believes about alcohol use

    Full Text Available Abstract Pharmacists, the most accessible of health care professionals, are well positioned to help prevent and treat substance use disorders and should prepare themselves to perform these functions. New research improves our knowledge about the pharmacological and behavioral risks of drug abuse, supports the clinical impression that drug dependence is associated with long-lasting neurochemical changes, and demonstrates effective pharmacological treatments for certain kinds of drug dependencies. The profession is evolving. Pharmacists are engaging in new practice behaviors such as helping patients manage their disease states. Collaborative practice agreements and new federal policies set the stage for pharmacists to assist in the clinical management of opioid and other drug dependencies. Pharmacists need to be well informed about issues related to addiction and prepared not only to screen, assess, and refer individual cases and to collaborate with physicians caring for chemically dependent patients, but also to be agents of change in their communities in the fight against drug abuse. At the end of this article the pharmacist will be better able to: 1. Explain the disease concept of chemical dependence 2. Gather the information necessary to conduct a screen for chemical dependence 3. Inform patients about the treatment options for chemical dependence 4. Locate resources needed to answer questions about the effects of common drugs of abuse (alcohol, marijuana, narcotics, "ecstasy", and cocaine 5. Develop a list of local resources for drug abuse treatment 6. Counsel parents who are concerned about drug use by their children 7.

    2007-06-01

    Caffeine is the most widely consumed psychoactive substance and is a legal stimulant that is readily available to children. Caffeine has occasionally been considered a drug of abuse and the potential for dependence on caffeine has been debated. Presently, due to a paucity of clinical evidence on caffeine dependence or abuse, no such diagnosis is included in the Diagnostic and Statistical Manual of Mental Disorder-fourth edition. The authors present two cases of abuse or dependence on the caffeine contained in 'eutrophic' (energy/nutritional) beverages or caffeine preparations, followed by a review of clinical studies demonstrating evidence that some people can manifest a clinical syndrome of caffeine dependence or abuse. The cases suggest that caffeine can produce a clinical dependence syndrome similar to those produced by other psychoactive substances and has a potential for abuse. In a recent study using a structured interview and the Diagnostic and Statistical Manual of Mental Disorder-fourth edition criteria for substance dependence and abuse, a subset of the general population was found to demonstrate caffeine dependence or caffeine abuse. Therefore, the authors propose that companies or businesses manufacturing or marketing caffeine or products containing caffeine must meet the following guidelines: (i) clearly indicate the caffeine content of products containing comparatively higher quantities of caffeine; (ii) warn that such products should be avoided by infants and children wherever possible, and inform adult consumers about the precise quantity of caffeine that is considered safe for consumption; and (iii) clearly state that consuming large quantities of caffeine and the long-term use of caffeine carry health risks.

    While childhood behaviors such as aggression, social withdrawal and likeability have been linked to substance abuse outcomes in adolescence and adulthood, the mechanisms by which these variables relate are not yet well established. Self and peer perceptions of childhood behaviors in men and women were compared to assess the role of context in the prediction of drug and alcohol abuse and dependence. Participants (N=676) in an ongoing longitudinal project examining the relation between childhood behavior and adult mental health outcomes completed the Structured Clinical Interview for the DSM IV regarding their histories of substance abuse in mid-adulthood (mean age=34, SD=2). In women, higher levels of both self and peer reported aggression were associated with drug and alcohol abuse and dependence, and higher levels of peer reported aggression were associated with higher levels of alcohol abuse and dependence. As well, higher levels of self-perceived likeability were protective regarding substance abuse and dependence outcomes. In men, higher levels of peer perceived social withdrawal were protective regarding substance abuse and dependence outcomes. Findings support the comparison of self and peer perceptions of childhood behavior as a method of assessing the mechanisms by which childhood behaviors impact adult outcomes, and suggest the importance of gender in the relation between childhood behaviors and adult substance abuse and dependence.

  12. Studying the factors in dependency to substances changing the mood and behavior and effective methods in drug addiction counseling

    Directory of Open Access Journals (Sweden)

    2004-05-01

    Full Text Available Addicts to alcohol and other substances changing the mood and behavior attempt to stop their addiction and avoid its relapse because they suffer mental and physical problems, they are under the pressure of family members, employer and other individuals who influence over their life as well as negative effects of drug addiction on their performance in family, work and social relations. Since drug addicts experience physical pain when they are not using drugs, they refer, at first, to physicians and then to psychiatrists. Although emerging and applying non-medical and non-pharmaceutical approaches models is not too old, arising various addictive drugs and increasing the number of drug addicts as well as individual/social destructive consequences of drug addiction have caused that psychiatrists, psychologists and social workers to represent various non-pharmaceutical theories, models, methods and guidelines based on the conditions of their clients and their clinical experiences. The present article attempts to identify the reasons of drug addiction tendency, consumption patterns, models, theories of addiction to substances changing the mood and behavior, various methods of drug treatment, effective methods in drug addiction counseling and non-medical and non-pharmaceutical methods to give up drug addiction by using recent research findings. On this basis, the most effective methods to help those who suffer from alcohol and other drugs abuse and dependency are studied.

    Full Text Available Abstract: Abortion is a very sensitive issue with relevance to public health; however few clinical or population-based studies have examined induced abortion among drug users. The study aims to evaluate the prevalence of induced abortion and sex-related conditions in an inpatient drug user sample. A cross-sectional design study was conducted in an inpatient addiction treatment unit in São Paulo, Brazil, with a sample of 616 patients, aged 18-75. Sociodemographic data, sexual behavior, and dependence severity were evaluated in relation to induced abortion. Approximately 27% of patients reported having a history of abortion (themselves in the case of women or partners in the case of men. The mean age was 34.6±10.9 years old, 34.9% diagnosed with severe alcohol dependence, 33% were diagnosed with severe levels of dependence on other drugs, 69.6% were diagnosed cocaine users (inhaled and smoked, and alcohol was the drug of choice for 30.4%. Chances of having a history of abortion is greater for women than for men with a odds ratio (OR = 2.9; 95%CI: 1.75-4.76, (OR = 1.7; 95%CI: 1.09-2.75 of no condom use; (OR = 2.0; 95%CI: 1.35-3.23 of history of STI and (OR = 3.2; 95%CI: 1.29-5.73 use of morning-after pill. Drug- and alcohol-dependent patients have high-risk behaviours of sporadic use or no-condom use which contribute to unplanned pregnancy and induced abortion, making this vulnerable population a group which deserves special attention in sexual health prevention programmes and health promotion efforts for the reduction of induced abortion.

    This study examined the role of workplace mandates to chemical dependency treatment in treatment adherence, alcohol and drug abstinence, severity of employment problems, and severity of psychiatric problems. The sample included 448 employed members of a private, nonprofit U.S. managed care health plan who entered chemical dependency treatment with a workplace mandate (N=75) or without one (N=373); 405 of these individuals were followed up at one year (N=70 and N=335, respectively), and 362 participated in a five-year follow up (N=60 and N=302, respectively). Propensity scores predicting receipt of a workplace mandate were calculated. Logistic regression and ordinary least-squares regression were used to predict length of stay in chemical dependency treatment, alcohol and drug abstinence, and psychiatric and employment problem severity at one and five years. Overall, participants with a workplace mandate had one- and five-year outcomes similar to those without such a mandate. Having a workplace mandate also predicted longer treatment stays and improvement in employment problems. When other factors related to outcomes were controlled for, having a workplace mandate predicted abstinence at one year, with length of stay as a mediating variable. Workplace mandates can be an effective mechanism for improving work performance and other outcomes. Study participants who had a workplace mandate were more likely than those who did not have a workplace mandate to be abstinent at follow-up, and they did as well in treatment, both short and long term. Pressure from the workplace likely gets people to treatment earlier and provides incentives for treatment adherence.

    Objective This study examined the role of workplace mandates to chemical dependency treatment in treatment adherence, alcohol and drug abstinence, severity of employment problems, and severity of psychiatric problems. Methods The sample included 448 employed members of a private, nonprofit U.S. managed care health plan who entered chemical dependency treatment with a workplace mandate (N=75) or without one (N=373); 405 of these individuals were followed up at one year (N=70 and N=335, respectively), and 362 participated in a five-year follow up (N=60 and N=302, respectively). Propensity scores predicting receipt of a workplace mandate were calculated. Logistic regression and ordinary least-squares regression were used to predict length of stay in chemical dependency treatment, alcohol and drug abstinence, and psychiatric and employment problem severity at one and five years. Results Overall, participants with a workplace mandate had one- and five-year outcomes similar to those without such a mandate. Having a workplace mandate also predicted longer treatment stays and improvement in employment problems. When other factors related to outcomes were controlled for, having a workplace mandate predicted abstinence at one year, with length of stay as a mediating variable. Conclusions Workplace mandates can be an effective mechanism for improving work performance and other outcomes. Study participants who had a workplace mandate were more likely than those who did not have a workplace mandate to be abstinent at follow-up, and they did as well in treatment, both short and long term. Pressure from the workplace likely gets people to treatment earlier and provides incentives for treatment adherence. PMID:19411353

    Illicit drug abuse has crossed social, economic, and geographical borders, and remains one of the major health problems that modern society is facing worldwide. The role of multiple drug abuse as a basic for chromosome damage has been overlooked and it is important to determine its possible adverse health effects. This study aimed to compare the frequency of chromosomal damages between drug addicts and free drug controls. Cytogenetic study was obtained from 146 illicit drug-users and 200 free drug controls. Subjects were grouped into three categories depending on main drug of dependence. Cytogenetic studies on cultured lymphocytes showed an increase the frequency of chromosomal damages among addicts including opiate (5.89%), heroin (7.65%), and crystal (4.9%) when compared with drug free controls (1.45%). The frequency of chromosomal abnormalities was breaks, gaps, marker, and acentric, respectively. Our findings are also important as they are among the first to suggest here, illicit drug addiction continue to be significant public health problems in Iran.

  19. Pleasure, power and dangerous substances: applying Foucault to the study of 'heroin dependence' in Germany.

    Taking the observation of disciplining and controlling everyday practices of methadone substitution as a point of departure, this paper explores the question of what exactly is so threatening or dangerous about heroin and heroin users. Drawing on the work of Michel Foucault and Judith Butler, the main argument of this article is that the danger of heroin use is a discursive construction in accordance with bio-power. On the one hand, the juridical governance of heroin dependence is shifting from punishment to therapy, and biomedical discourses proclaim the substitution of a moral notion of heroin dependence by a disease model. Nevertheless, in the context of the anxiety associated with HIV, heroin remains the dangerous drug par excellence, and heroin users are constructed as 'abject others', unable to subordinate to certain social norms. As a reaction to such injurious ascriptions, I argue, applicants to the methadone programme in their life stories intensely narrate a desire for normalization, which I read as a desire to emerge from the realm of the abject. Both the danger and the pleasure associated with heroin use are bound to fundamental processes of subject formation, which are often ignored in biomedical and anthropological discourses.

    Full Text Available Background. TEN-D by Night is an international, multicentre, cross-sectional portal survey conducted on a large sample of young people in six European countries. This paper aims to investigate the alcohol and psychoactive drug consumption of this sample, with a focus on the prevalence of binge drinking and the poly-drug habits of the TEN-D cohort. Design and Methods. The study population consisted of 4695 young people attending recreational sites on weekend nights. The intervention included two questionnaires and two psychoactive substance detection tests performed at the entry and exit of the recreational sites. A multivariate logistic regression model was used to predict the probability of binge drinking. Results. Binge drinking was reported by 20% of the males and 13% of the females (P=0.001 before entry into the recreational sites and by 18% of the males and 11% of the females before entry into the clubs (P<0.001. Poly-drug use was reported by 71% of the males and 66% of the females. Living with a parent (OR 1.57; P=0.01, seeking employment (OR 1.66; P=0.005 and cannabis consumption (several times per month and several times per week, OR 1.94 and 3.66, respectively, P<0.05 were associated with binge drinking. Conclusions. Our survey showed that it is possible to identify individuals and groups at higher risk of binge drinking. This identification would allow for a focus on specific targets and would facilitate the redesign of prevention programmes. The increased use of psychoactive substances among youths should be studied extensively to promote successful prevention campaigns.

    Full Text Available Abstract Background A high prevalence of lifetime psychiatric disorders among help-seeking substance abusers has been clearly established. However, the long-term course of psychiatric disorders and mental distress among help-seeking substance abusers is still unclear. The aim of this research was to examine the course of mental distress using a six-year follow-up study of treatment-seeking substance-dependent patients, and to explore whether lifetime Axis I and II disorders measured at admission predict the level of mental distress at follow-up, when age, sex, and substance-use variables measured both at baseline and at follow-up are controlled for. Methods A consecutive sample of substance dependent in- and outpatients (n = 287 from two counties of Norway were assessed at baseline (T1 with the Composite International Diagnostic Interview (Axis I, Millon's Clinical Multiaxial Inventory (Axis II, and the Hopkins Symptom Checklist (HSCL-25 (mental distress. At follow-up (T2, 48% (137/287 subjects, 29% women were assessed with the HSCL-25, the Alcohol Use Disorders Identification Test, and the Drug Use Disorders Identification Test. Results The stability of mental distress is a main finding and the level of mental distress remained high after six years, but was significantly lower among abstainers at T2, especially among female abstainers. Both the number of and specific lifetime Axis I disorders (social anxiety disorder, generalized anxiety disorder, and somatization disorder, the number of and specific Axis II disorders (anxious and impulsive personality disorders, and the severity of substance-use disorder at the index admission were all independent predictors of a high level of mental distress at follow-up, even when we controlled for age, sex, and substance use at follow-up. Conclusion These results underscore the importance of diagnosing and treating both substance-use disorder and non-substance-use disorder Axis I and Axis II disorders in

    Numerous prospective studies have shown that children diagnosed with attention deficit/hyperactivity disorder (ADHD) are at higher risk of long-term substance abuse/dependence. However, there are three important limits to these studies: (a) most did not differentiate the role of hyperactivity and inattention; (b) most did not control for associated behavioral problems; and (c) most did not consider females. Our aim was to clarify the unique and interactive contributions of childhood inattention and hyperactivity symptoms to early adulthood substance abuse/dependence. Behavioral problems of 1803 participants (814 males) in a population-based longitudinal study were assessed yearly between 6 and 12 years by mothers and teachers. The prevalence of substance abuse/dependence at age 21 years was 30.7% for nicotine, 13.4% for alcohol, 9.1% for cannabis and 2.0% for cocaine. The significant predictors of nicotine dependence were inattention (odds ratio (OR): 2.25; 95% confidence interval (CI): 1.63-3.11) and opposition (OR: 1.65; 95%: 1.20-2.28). Only opposition contributed to the prediction of cannabis dependence (OR: 2.33; 95% CI: 1.40-3.87) and cocaine dependence (OR: 2.97; 95% CI: 1.06-8.57). The best behavioral predictor of alcohol abuse/dependence (opposition) was only marginally significant (OR: 1.38; 95% CI: 0.98-1.95). Frequent oppositional behaviors during elementary school were clearly the most pervasive predictors of substance abuse/dependence in early adulthood. The association of childhood ADHD with substance abuse/dependence is largely attributable to its association with opposition problems during childhood. However, inattention remained an important predictor of nicotine dependence, in line with genetic and molecular commonalities between the two phenotypes suggested in the literature.

    Bioethicists have warned against the dangers of mixing research with treatment. They are concerned that research priorities may take precedence over individual patient needs and that research subjects tend to misunderstand the purpose of research or overestimate the direct medical benefits of participating in studies. Yet, other work has questioned whether clinical research can always be separated from therapeutic benefit for participants. Using in-depth interviews with participants in two phase III randomized U.S. clinical trials for methamphetamine dependency, we examine the treatment options available to participants, their experiences with participating in the trials, and potential problems of trial participation. We find that while participants have experience with four alternative treatment modalities - quitting alone, support groups, in-patient treatment facilities, and consulting primary care physicians - the randomized clinical trials compare favorably to alternatives because they provide access to evidence-based behavioral treatments, specialized medical professionals, non-judgmental staff, and the possibility of receiving an experimental drug. We conclude that while randomized clinical trials are imperfect substitutes for clinical care, they constitute a fragile and sporadic therapeutic niche in a country with fundamental problems in access to health care, a mixed punitive-therapeutic drug addiction policy, and a profit-driven pharmaceutical development and approval process.

    There is growing interest in plants with psychoactive effects among consumers with different levels of experience. This has generated a need for updated knowledge among medical professionals and other health workers. These plants, which may be used in shamanic healing ceremonies or rituals or just for traditional purposes, have emerged in the Western world as new psychoactive drugs; largely thanks to the ease of purchase, sale, cultivation and exchange of information that the Internet offers. This review summarizes the current knowledge about the most important psychoactive plants, either by their mention in Internet forums or harm-reduction portals or by their allusion in scientific texts.

  5. Investigating nitrate-dependent humic substance oxidation and in-service K-12 teachers' understanding of microbiology

    Humic substances (HS) are the humified portions of totally decomposed soil organic matter that are ubiquitous in nature. Although these substances have been studied for more than 200 years, neither their metabolic capabilities nor a specific chemical structure has yet to be determined. HS have been studied as a carbon source in many environments where they are degraded; however, previous studies have shown that some microorganisms are capable of utilizing humic substances as electron acceptors and electron donors in anaerobic respiration. Even though there have been humic-reducing and humic-oxidizing microorganisms isolated and studied in recent years, the mechanism of humics metabolism and its interaction in the natural environment are not well understood. However, it is known that the continuous change in the redox state of HS is important to the cycling of iron, stability of nitrogen and carbon, and the mobility and bioavailability of inorganic and organic environmental pollutants. In this study, microbial communities were examined to evaluate the community dynamics of nitrate-dependent HS-oxidizing populations and to provide a snapshot of the phylogenetic diversity of these microorganisms. Column studies were performed using nitrate as the sole electron acceptor and the following as the electron donors in different columns: reduced humic acids, oxidized humic acids, and acetate as the control. Liquid buffered media was added to a separate column to serve as an additional control. Polymerase chain reactions of the 16S rRNA genes using DNA from the column studies were performed and analyzed by constructing 16S rDNA clone libraries and by performing denaturing gradient gel electrophoresis (DGGE). Clones from the library have been sequenced and analyzed to paint a phylogenetic picture of the microbial community under the various conditions. Results indicate that the majority of the clones were assigned to four well-characterized divisions, the Acidobacteria, the

    In the last two decades, the consumption of drugs of abuse among women of childbearing age has experienced a significant increase and results from analyses of surveys concerning maternal intake of psychoactive prescription drugs during pregnancy indicate that the rates of intake are increasing each year. Analyses of biological matrices such as maternal hair and neonatal meconium have recently been used for assessment of gestational consumption and consequent prenatal exposure to drugs of abuse in high-risk groups of women METHODS: Maternal hair and neonatal meconium were analyzed by validated chromatographic mass spectrometric methodologies to disclose gestational use of drugs of abuse and psychoactive prescription drugs and consequent prenatal exposure in a cohort of 513 mother-newborn dyads at the Sant Joan de Déu Barcelona Hospital, Spain, during 2012- 2013. A total of 3.9% the women reported drugs of abuse or prescription psychoactive drug consumption at any time during pregnancy. The prevalence of gestational consumption and consequent prenatal exposure to drugs of abuse (e.g. cannabis, cocaine and MDMA) was 1.2% in maternal hair and 0.4% in meconium; that of psychoactive prescription drugs (e.g. venlafaxine, citalopram, fluoxetine, clomipramine) was 1.7% in maternal hair and 1.2% in meconium. The prevalence of drugs of abuse and prescription psychoactive drug consumption was lower in our specific cohort of Spanish pregnant women than in other cohorts such as those from U.S. or Denmark. Analysis of materno-fetal matrices provides a viable alternative to study prenatal exposure to these substances and develop specific social and health intervention recommendations.

    Novel forest decline is particularly pronounced in the area of the ridges of medium-range mountains. Whereas acid precipitation was viewed as its sole cause early on in the discussions, it turned out later that the impact of trace gases, too, contributes to the damaging of forests. This report wants to point out the importance of fog interception, which equally plays a part in the pollutant receipts of forests. The deposition of fog water to a forest stand depends very much on altitude, so that trace substance deposition, too, is to be expected to be dependent on altitude. By attempting to quantify this effect, the report helps to pinpoint areas of relevance of this deposition pathway (orig./KW) [Deutsch] Die neuartigen Waldschaeden sind in den Kammlagen der Mittelgebirge besonders ausgepraegt. Waehrend in der anfaenglichen Diskussion die sauren Niederschlaege als alleinige Ursache angesehen wurden, zeigte sich spaeter, dass auch Einwirkungen von Spurengasen zur Schaedigung des Waldes beitragen. Dieser Bericht soll auf die Bedeutung der Nebelinterzeption aufmerksam machen, die ebenfalls zum Schadstoffeintrag in den Wald beitraegt. Die Deposition von Wolkenwasser auf einen Waldbestand ist stark abhaengig von der Hoehenlage, in der sich der Waldbestand befindet, so dass auch eine Hoehenabhaengigkeit des Spurenstoffeintrages zu erwarten ist. Durch den Versuch der Quantifizierung traegt dieser Bericht dazu bei, Gebiete zu erkennen, in denen dieser Eintragspfad eine Rolle spielt. (orig./KW)

    A number of demographic factors, psychiatric disorders, and childhood risk factors have been associated with cocaine dependence (CD) and opioid dependence (OD), but little is known about their relevance to the rate at which dependence develops. Identification of the subpopulations at elevated risk for rapid development of dependence and the risk factors that accelerate the course of dependence is an important public health goal. Data were derived from cocaine dependent (n=6333) and opioid dependent (n=3513) participants in a multi-site study of substance dependence. Mean age was approximately 40 and 40% of participants were women; 51.9% of cocaine dependent participants and 29.5% of opioid dependent participants self-identified as Black/African-American. The time from first use to dependence was calculated for each substance and a range of demographic, psychiatric, and childhood risk factors were entered into ordinal logistic regression models to predict the (categorical) transition time to CD and OD. In both the cocaine and opioid models, conduct disorder and childhood physical abuse predicted rapid development of dependence and alcohol and nicotine dependence diagnoses were associated with slower progression to CD or OD. Blacks/African Americans were at greater risk than European Americans to progress rapidly to OD. Only a subset of factors known to be associated with CD and OD predicted the rate at which dependence developed. Nearly all were common to cocaine and opioids, suggesting that sources of influence on the timing of transitions to dependence are shared across the two substances. © 2013.

    One of the main challenges posed by the emergence of new psychoactive substances is their identification in human biological samples. Trying to detect the parent drug could lead to false-negative results when the delay between consumption and sampling has been too long. The identification of their metabolites could then improve their detection window in biological matrices. Oxidative metabolism by cytochromes P450 and glucuronidation are two major detoxification pathways in humans. In order to characterize possible CYP- and UGT-dependent metabolites of the 2-(4-bromo-2,5-dimethoxy-phenyl)-N-[(2-methoxyphenyl)methyl]ethanamine (25B-NBOMe), a synthetic psychoactive drug, analyses of human liver microsome (HLM) incubates were performed using an ultra-high performance liquid chromatography system coupled with a quadrupole-time of flight mass spectrometry detector (UHPLC-Q-TOF/MS). On-line analyses were performed using a Waters OASIS HLB column (30 x 2.1 mm, 20 µm) for the automatic sample loading and a Waters ACQUITY HSS C18 column (150 x 2 mm, 1.8 µm) for the chromatographic separation. Twenty-one metabolites, consisting of 12 CYP-derived and 9 UGT-derived metabolites, were identified. O-Desmethyl metabolites were the most abundant compounds after the phase I process, which appears to be in accordance with data from previously published NBOMe-intoxication case reports. Although other important metabolic transformations, such as sulfation, acetylation, methylation or glutathione conjugation, were not studied and artefactual metabolites might have been produced during the HLM incubation process, the record of all the metabolite MS spectra in our library should enable us to characterize relevant metabolites of 25B-NBOMe and allow us to detect 25B-MBOMe users.

    To establish the prevalence of psychoactive drug consumption in an obese population. We collected data from the clinical records of obese patients attending the Endocrinology and Nutrition Department and Psychiatry Department of Hospital del Mar between June 2005 and May 2006 (n=259). We recorded anthropometric, epidemiological and toxicological data. We also investigated the prevalence of concomitant diseases in this population. Psychoactive drugs were consumed by 37% of obese patients, mainly antidepressants (27%), anxiolytics, sedatives and hypnotics, and anticonvulsants. Moreover, 15% of all patients received combination treatment with two or more psychoactive drugs, mostly the association of an antidepressant and an antiepileptic drug. The prevalence of psychoactive drug consumption in our sample was higher than prevalence data observed in the general population, with antidepressant consumption being three-fold higher.

    The aim of this study was to examine early signs of psychosis in patients suffering from both drug dependence and schizophrenia, compared to a control group of drug-addicted patients without a comorbid psychotic disorder, and to assess whether the presence of these signs was related to changes in the pattern of substance abuse. In a rehabilitation hospital for young addicts, 32 patients with a comorbid diagnosis of schizophrenia and 30 patients without the diagnosis of a psychotic disorder, were assessed using the Interview for the Retrospective Assessment of the Onset of Schizophrenia. Information relating to 64 signs of early psychosis was collected from every patient. From the 64 signs, five groups of symptoms were defined: non-specific and precursor symptoms; non-specific and depressive symptoms; negative symptoms; positive symptoms; and impaired social adjustment. The semiquantitative pattern of substance abuse for each 1-year interval over the previous 10 years was investigated using the categories of chapter F1 of ICD-10 and including an additional category "biological drugs". The relationship between the pattern of substance abuse and the presence of early signs was assessed using anova and non-parametric statistical methods. The results indicate that the defined pathological symptomatology greatly influences the pattern of consumption of psychoactive substances in both the psychosis group and the control group. The group factor exerted the greatest influence within the categories "biological drugs" and "other stimulants", where the "psychosis and addiction group" consumed significantly more than the control group. There is a subgroup of non-psychotic addicted patients whose pattern of psychoactive substance abuse is similar to that found in addicted patients suffering from schizophrenia. It may be helpful to systematically identify this subgroup with regard to possible therapeutic implications, particularly with regard to possible pharmacological treatment

    Previous studies have shown that when assessing child psychopathology, parents tend to report more symptoms than children for externalizing disorders such as attention deficit hyperactivity disorder (ADHD), whereas children tend to report more symptoms for internalizing disorders such as major depression. Whether for clinical or research purposes, parents are also frequently asked to report on their children's experiences with alcohol and drugs. The purpose of this study was to analyze correspondence between adolescent and parent reports of adolescent substance use and abuse or dependence. In the current study, 591 subjects 12 to 17 years old were interviewed using the child version of the Semi-Structured Assessment for the Genetics of Alcoholism (C-SSAGA) as part of the Collaborative Study on the Genetics of Alcoholism (COGA). One parent was also interviewed about each adolescent using the parent version of the C-SSAGA. Sensitivities, specificities, and kappa coefficients were calculated to assess parental agreement with adolescent reports of lifetime substance use and Diagnostic and Statistical Manual of Mental Disorders-Third Revision substance abuse or dependence. The results indicate that parents are somewhat knowledgeable about their children's use of substances, particularly those that are used most commonly. For example, 55% of adolescents who had smoked cigarettes, 50% who had used alcohol, and 47% who had used marijuana had a parent who knew that they used. However, parents were less aware of substance-related problems experienced by their offspring, agreeing with adolescent reports only 27% of the time for diagnoses of alcohol abuse or dependence and 26% of the time for diagnoses of marijuana abuse or dependence. Parent reports added few cases of substance use for 12- to 13 year-olds and essentially no cases for 16- to 17-year-olds. Parent reports added a nominal number of diagnoses of substance abuse or dependence for older adolescents. Whether for

    The WHO Executive Board revised the guidance that governs the procedures for the WHO review of psychoactive substances for international drug control in 2010. To meet the standards defined in these guidelines, the current evaluation methodology at WHO must be an evidence-based assessment. We describe the history of substance evaluation from 1912 to the present and the development of the evaluation methods over time including a description of the current assessment system, using reports from WHO and its predecessor, the League of Nations. Furthermore, we describe the current review system. We found that some substances under international control were never reviewed; other substances were reviewed decades ago. We argue that assessments do not have unlimited validity, and therefore, substances need to be re-assessed periodically, as already recommended by the Expert Committee on Drug Dependence in 1982. We propose that the evaluation time be shortened; that the influence of the route of administration and/or dosage form of the preparation is considered in the evaluation; and we recommend studying national and regional assessment systems and adopting their best practices. With this article, we make a case for the inclusion of systematic review and other methods of comprehensive analysis of substance evaluation to arrive at a process of equal rigour and quality as already applied by WHO for the development of treatment guidelines.

    In this article the research directed on development of a technique of definition of time of induction of the self-ignition of substances and materials which is an indicator of the beginning of development of an emergency is conducted. The experiment consisting in supervision over process of self-ignition of coal and oil deposits was the basis for research. On the basis of experimental data the curve expressing analytic - expected dependence of size of temperature of ignition on induction time was constructed. Proceeding from graphical representation of process, functional dependence of time of induction on a temperature indicator was received: y = 16920 • x 0 537 . By means of known indicators of such substances as bitumen oil oxidized (the combustible solid substance received by oxidation of residual product of oil refining) and tar oil (the combustible solid substance which is residual product of oil refining) and the received algorithm, verification of reliability of the received dependence and a technique of definition of time of induction of spontaneous ignition of deposits of oil in general was carried out. The practical importance of the conducted research is that having data on time of induction of process of self-ignition, by means of preventive measures becomes possible to avoid and prevent accidents in oil and oil processing branches, at the same time loss of property and loss of human life.

    The study was conducted in response to the lack of epidemiological data in recent time on the use of psychoactive substances by adolescents in metropolitan Lagos-a city unique for its socio-economic profile. We considered some methodological issues omitted in several previous studies. A total of 4,286 school pupils (mean age 15.2) were anonymously administered a Self-Report Questionnaire to ascertain a range of key drug use factors in lifetime and 1-year periods. The rate of use of most of the 14 substances investigated was much higher than reported in any other study on comparable population sample. We found that 61.8 and 32.1% of respondents have used one or more substances in their lifetime and in the past 1 year, respectively. High lifetime rates of use were found for common stimulants: coffee, kolanut, and prescription drugs (barbiturates and minor tranquilisers). The rate of use of proscribed addictive substances, cannabis, heroin, and cocaine, ranged between 4.0 and 4.8%. Missing data and non-response rates were few; however, social acquiescence, under and over reporting, could be mitigant to estimation of rates and patterns of use. We advocate properly articulated school-based educative programmes that can facilitate drug demand reduction.

    Ritual use of ayahuasca within the context of the Brazilian ayahuasca churches often starts during late childhood or early adolescence. Premature access to psychoactive drugs may represent a risk factor for drug misuse. Conversely, religious affiliation seems to play a protective role in terms of substance abuse. The objective of this study was to describe patterns of drug use in a sample of adolescents using ayahuasca within a religious setting. Forty-one adolescents from a Brazilian ayahuasca sect were compared with 43 adolescents who never drank ayahuasca. No significant differences were identified in terms of lifetime substance consumption. Throughout the previous year period, ayahuasca adolescents used less alcohol (46.31%) than the comparison group (74.4%). Recent use of alcohol was also more frequent among the latter group (65.1%) than among ayahuasca drinkers (32.5%). Although not statistically significant, slight differences in terms of patterns of drug use were definitely observed among groups. Despite their early exposure to a hallucinogenic substance, adolescents using ayahuasca in a controlled setting were mostly comparable to controls except for a considerably smaller proportion of alcohol users. Religious affiliation may have played a central role as a possible protective factor for alcohol use. Thus, ayahuasca seems to be a relatively safe substance as far as drug misuse is concerned.

    Full Text Available This study was performed on a representative sample of the Danish population in order to investigate the connection to the use of psychoactive drugs and quality of life (QOL by way of a questionnaire-based survey. The questionnaire was mailed in February 1993 to 2,460 persons aged between 18 and 88, randomly selected from the CPR (Danish Central Register, and 7,222 persons from the Copenhagen Perinatal Birth Cohort 1959–61.A total of 1,501 persons between the ages 18 and 88 years and 4,626 persons between the ages 31 and 33 years returned the questionnaire (response rates of 61.0% and 64.1%, respectively. Variables investigated in this study were ten different psychotropic drugs and quality of life.Our study showed that over half the Danish population had used illegal psychotropic drugs. The most commonly used was cannabis (marijuana though experience of this drug appeared not to co-vary with QOL to any significant extent. Cocaine, amphetamine, and psilocybin had been used by 1.2 to 3.3% of the population and this varied with QOL to a clear albeit small extent. LSD has been used by 1.2% of the population and the users had a QOL score 10% lower than those who had never used psychotropic drugs. The group with the lowest quality of life was found to be persons who had used heroin, morphine, methadone, and a mixture of alcohol and tranquilizers (10–20% below the group with the highest quality of life.

    Full Text Available The study was to survey and assess the drug dependence and abuse potential of tramadol with no history of substance abuse. Subjects of tramadol dependence with no prior history of substance abuse were surveyed by interview. Physical dependence of tramadol was assessed using 10 items opiate withdrawal scale (OWS, and psychological dependence was assessed by Addiction Research Center Inventory—Chinese Version (ARCI-CV. Twenty-three male subjects (the median age was 23.4±4.1 years referred to the addiction unit in Medical Hospital of Guangzhou with tramadol abuse problems were included in this cross-sectional study. The control group included 87 heroin addicts, 60 methamphetamine (MA abusers, and 50 healthy men. The scores of OWS of tramadol were 0.83–2.30; the mean scores of identifying euphoric effects–MBG, sedative effects–PCAG, and psychotomimetic effects–LSD of ARCI were 8.96±3.08, 6.52±3.25, and 6.65±2.50, respectively, F = 4.927, P0.05 but were higher than those in healthy men (P<0.05. Tramadol with no history of substance abuse has a clear risk of producing high abuse potential under the long-term infrequent abuse and the high doses.

    This cross-sectional study sought to determine the prevalence of attention-deficit/hyperactivity disorder (ADHD) and conduct disorder among adults admitted to 2 chemical dependency treatment centers. It was hypothesized that ADHD alone or in combination with conduct disorder would be overrepresented in a population of patients with psychoactive substance use disorders. Two hundred one participants were selected randomly from 2 chemical dependency treatment centers. Standardized clinical interviews were conducted using the Structured Clinical Interview for DSM-IV, the Addiction Severity Index, and DSM-IV criteria for ADHD. Reliabilities for the diagnostic categories were established using the Cohen kappa, and the subgroups of individuals with and without ADHD and conduct disorder were compared. Forty-eight (24%) of the participants were found to meet DSM-IV criteria for ADHD. The prevalence of ADHD was 28% in men (30/106) and 19% in women (18/95; NS). Seventy-nine participants (39%) met criteria for conduct disorder, and 34 of these individuals also had ADHD. Overall, individuals with ADHD (compared with those without ADHD) were more likely to have had more motor vehicle accidents. Women with ADHD (in comparison with women without ADHD) had a higher number of treatments for alcohol abuse. Individuals with conduct disorder (in comparison with those without conduct disorder) were younger, had a greater number of jobs as adults, and were more likely to repeat a grade in school, have a learning disability, be suspended or expelled from school, have an earlier age at onset of alcohol dependence, and have had a greater number of treatments for drug abuse. They were more likely to have a lifetime history of abuse of and/or dependence on cocaine, stimulants, hallucinogens, and/or cannabis. A significant overrepresentation of ADHD exists among inpatients with psychoactive substance use disorders. Over two thirds of those with ADHD in this sample also met criteria for conduct

    Cognitive-behavioral therapy (CBT) that has been modified to incorporate clients' spiritual beliefs and practices has been used to treat a variety of problems. This study examines the utility of this modality with the treatment of alcohol dependence and other forms of substance abuse. Toward this end, six focus groups (three therapist groups and three client groups) were conducted to identify the presumed benefits and limitations of using spiritually modified CBT in substance dependence treatment. In terms of benefits, spiritually modified CBT was perceived to enhance outcomes through operationalizing horizontal and vertical sources of social support, divine coping resources, and spiritual motivation. Potential challenges include the risk of therapists inadvertently imposing their own beliefs during the modification process and the possibility of offending clients when conflicts in belief systems emerge, particularly in group setting. The article concludes by providing suggestions for incorporating spiritually modified CBT into treatment and develops a number of illustrative examples of spiritually modified CBT self-statements.

    Novel treatments for substance use disorders are needed. Acute bouts of exercise can improve mood states in non-clinical populations, but effects in those with poly-substance dependence are understudied. We examined the feasibility and short-term effects of three types of exercise on drug cravings, self-esteem, mood and positive/negative affect in nine poly-drug-dependent inpatients. Using a cross-over design, changes in the four study outcomes were assessed immediately before exercise and on four separate occasions post-exercise (immediately after, then at 1, 2 and 4 h post-exercise) enabling patterns of change over time (analysis of covariance) to be observed. Participants were willing and able to engage in different non-laboratory based exercises. Football was associated with non-significant short-term reductions in drug cravings. A similar trend was seen for circuit-training, but not walking. Football and circuit-training were associated with brief improvements in mood and positive/negative affect. No adverse events were reported. Football, circuit training and walking are feasible therapeutic activities for inpatients with poly-substance dependence. Controlled trials are needed to determine the long-term effects of these activities. © 2018 Australasian Professional Society on Alcohol and other Drugs.
