    2009-05-01

    Intrinsic vulnerability is central to the transition of recreational drug use to misuse. Several factors contribute to vulnerability, inherent or acquired, and they account for the huge individual differences observed concerning the propensity to enter in the addiction process. Some of the multifactional causes for a vulnerable phenotype will be examined: genetic factors, age and gender influences, various comorbidities and epidemiological observations. Stress-induced vulnerability will be particularly reviewed because it provides a good model for a pathophysiological research and for relating environmental events to biological consequences of drug vulnerability, namely through the striato-cortical dopamine system. Experimental studies are generally blind concerning these historical factors that contribute vulnerability and a critical evaluation of current animal models is needed. The transition of the last stage of the process, addiction, is conceptualized as a progression from homeostasis to allostasis and then, to pathology.

    To describe the design, implementation, and student perceptions of a Drugs of Abuse and Addiction elective course utilizing an integrated teaching model. Third-year pharmacy students enrolled in the two credit hour elective. Teaching methodology included didactic lecture, journal club, simulated addiction assignment with reflection, debates, external speakers, site visit to a residential drug court program and research paper with presentation. A course objective survey was administered upon course completion. All students strongly agreed that having science- and clinical-based faculty members develop and deliver course content was beneficial. Additionally, all students agree to strongly agree that their research project helped them integrate and comprehend the science and practice surrounding drugs of abuse and addiction. Students enjoyed an integrated teaching approach and multiple teaching methodologies leading to increased engagement and enhancement of student learning. Course enrollment was beneficial for personalized learning, but limited student perspective. Copyright © 2017 Elsevier Inc. All rights reserved.

Not surprisingly, there is a high percentage of prisoners who during sentence execution abuse or are dependent on drugs. Antisocial personality disorder can be considered a common predictor of committing criminal offenses and drug abuse. A review of studies has revealed a high prevalence of inmates who use drugs while serving a sentence. Also, prison environment represents only a new context of the continuum of drug abuse by inmates. There are different theoretical approaches in explaining this phenomenon. Treatment programs based on empirically validated principles that guarantee the effectiveness, may be one strategy for solving the problem of drug abuse in prisons, with multiple positive effects.

    Full Text Available Abstract Background Opiates are the main drugs of abuse, and Methadone Maintenance Treatment (MMT is the most widely administered drug addiction treatment program in Iran. Our study aimed to investigate patterns of pre-treatment drug abuse, addiction treatment history and characteristics of patients in MMT in Tehran. Methods We applied a stratified cluster random sampling technique and conducted a cross-sectional survey utilizing a standard patient characteristic and addiction history form with patients (n = 810 in MMT. The Chi-square test and t-test served for statistical analyses. Results A clear majority of the participants were men (96%, more than 60% of whom were between 25 and 44 years of age, educated (89% had more than elementary education, and employed (>70%. The most commonly reported main drugs of abuse prior to MMT entry were opium (69% and crystalline heroin (24%. The patients’ lifetime drug experience included opium (92%, crystalline heroin (28%, cannabis (16%, amphetamines (15%, and other drugs (33%. Crystalline heroin abusers were younger than opium users, had begun abusing drugs earlier, and reported a shorter history of opiate addiction. Conclusion Opium and crystalline heroin were the main drugs of abuse. A high rate of addiction using more dangerous opiate drugs such as crystalline heroin calls for more preventive efforts, especially among young men.

    Immunotherapeutic vaccines to drugs of abuse, including nicotine, cocaine, heroin, oxycodone, methamphetamine, and others are being developed. The theoretical basis of such vaccines is to induce antibodies that sequester the drug in the blood in the form of antibody-bound drug that cannot cross the blood brain barrier, thereby preventing psychoactive effects. Because the drugs are haptens a successful vaccine relies on development of appropriate hapten-protein carrier conjugates. However, because induction of high and prolonged levels of antibodies is required for an effective vaccine, and because injection of T-independent haptenic drugs of abuse does not induce memory recall responses, the role of adjuvants during immunization plays a critical role. As reviewed herein, preclinical studies often use strong adjuvants such as complete and incomplete Freund's adjuvant and others that cannot be, or in the case of many newer adjuvants, have never been, employed in humans. Balanced against this, the only adjuvant that has been included in candidate vaccines in human clinical trials to nicotine and cocaine has been aluminum hydroxide gel. While aluminum salts have been widely utilized worldwide in numerous licensed vaccines, the experience with human responses to aluminum salt-adjuvanted vaccines to haptenic drugs of abuse has suggested that the immune responses are too weak to allow development of a successful vaccine. What is needed is an adjuvant or combination of adjuvants that are safe, potent, widely available, easily manufactured, and cost-effective. Based on our review of the field we recommend the following adjuvant combinations either for research or for product development for human use: aluminum salt with adsorbed monophosphoryl lipid A (MPLA); liposomes containing MPLA [L(MPLA)]; L(MPLA) adsorbed to aluminum salt; oil-in-water emulsion; or oil-in-water emulsion containing MPLA.

    The mental health problems and pathways to drug addiction and crime among female inmates have long been of interest to researchers and practitioners. The purpose of the current study was to examine the possible association between multiple types of childhood abuse, mental health problems, and drug addiction and the incarceration of 50 Israeli women in prison. The findings indicated that female inmates come from risky families with a high prevalence of family mental health problems, parental drug addiction and crime, and sibling drug addiction and crime. Furthermore, they revealed that incarcerated women from risky families were victims of multiple types of childhood abuse and neglect by their parents, as well as their siblings. Overall, the results suggest that the adverse consequences of a family's mental health problems are much more dramatic than we assumed to date, and that women are more likely than men to be the victims of multiple types of childhood abuse and neglect, as well as suffering more severe psychiatric problems, depression, and drug addiction. The implications of these findings are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The aim of the present study was to clarify the association between child abuse experiences and drug addiction severity among Japanese drug-dependent patients using the Addiction Severity Index-Japanese version (ASI-J). One hundred and eleven inpatients and outpatients with drug dependence participated in the study. Some of the questions on the ASI-J asked about lifetime experiences of abuse. A higher percentage of female participants experienced child abuse compared with male participants. Male participants who experienced child abuse (MEA) had a significantly higher severity of drug use than men who did not experience it (MNEA). Female participants who experienced child abuse (FEA) had significantly more serious problems in family/social relationships than female participants who did not experience it (FNEA). Patients in the MEA group were arrested less frequently for drug charges, experienced more serious problems with their fathers, and experienced more severe anxiety in their lifetime compared with the MNEA group. The FEA group experienced more serious troubles with their sexual partners, close friends, and families and experienced more severe psychiatric problems in their lifetime compared with the FNEA group. These results suggest gender differences in the problems experienced by drug-dependent patients with child abuse experiences, and gender-specific interventions may be more effective in treating their drug dependence.

    Full Text Available This article focuses on the quantitative grounds for the emergence and spread of addiction among women, its medical, social and psychological problems, impediments for the treatment of addiction among women as well as gender differences concerning drug abuse and its treatment. This article is a translation of a statistical research on addiction among women and a number of other researches. Based on conclusions drawn from the said researches, women become inclined to addiction mostly by their husbands due to their cordial relationships. Moreover, the negative attitudes of peer groups can overshadow girls and women more than boys and men. From the viewpoint of psychological disorders, the relationship between disorders resulting from psychological pressure after an incident and addiction is stronger among girls and women compared to boys and men. Addiction among women in addition to certain ailments such as malnutrition, hypertension and cancer, can expose them to dangerous diseases such as Hepatitis and AIDS. There is more possibility for addicted women to be infected with AIDS and other sexually transmitted diseases compared to men and they are more exposed to female ailments compared to other women. As far as treatment impediments are concerned, women face a greater social stigma due to their addiction compared to men. Social approach considering addicted women as an indecent person is a major impediment for their treatment. Taking care of the child is also another obstacle for their treatment. There is less possibility for women to receive support from their families for quitting their addiction compared to men. Treatment programs also unwantedly may create obstacles for the treatment of women such as financial constraints, administrative bureaucracy, concentration of treatment programs for men and lack of sensitivity towards women’s addiction. The psychological impediments to treatment include internalizing the notion that addiction is a

    Substances of abuse induce alteration in neurobehavioral symptoms, which can lead to simultaneous exacerbation of liver injury. The biochemical changes of liver are significantly observed in the abused group of people using illicit drugs or drugs that are abused. A huge amount of work has been carried out by scientists for validation experiments using animal models to assess hepatotoxicity in cases of drugs of abuse. The risk of hepatotoxicity from these psychostimulants has been determined by different research groups. Hepatotoxicity of these drugs has been recently highlighted and isolated case reports always have been documented in relation to misuse of the drugs. These drugs induce liver toxicity on acute or chronic dose dependent process, which ultimately lead to liver damage, acute fatty infiltration, cholestatic jaundice, liver granulomas, hepatitis, liver cirrhosis etc. Considering the importance of drug-induced hepatotoxicity as a major cause of liver damage, this review emphasizes on various drugs of abuse and addiction which induce hepatotoxicity along with their mechanism of liver damage in clinical aspect as well as in vitro and in vivo approach. However, the mechanisms of drug-induced hepatotoxicity is dependent on reactive metabolite formation via metabolism, modification of covalent bonding between cellular components with drug and its metabolites, reactive oxygen species generation inside and outside of hepatocytes, activation of signal transduction pathways that alter cell death or survival mechanism, and cellular mitochondrial damage, which leads to alteration in ATP generation have been notified here. Moreover, how the cytokines are modulated by these drugs has been mentioned here. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  3. Appropriate experimental approaches for predicting abuse potential and addictive qualities in preclinical drug discovery.

    2014-11-01

    Drug abuse is an increasing social and public health issue, putting the onus on drug developers and regulatory agencies to ensure that the abuse potential of novel drugs is adequately assessed prior to product launch. This review summarizes the core preclinical data that frequently contribute to building an understanding of abuse potential for a new molecular entity, in addition to highlighting models that can provide increased resolution regarding the level of risk. Second, an important distinction between abuse potential and addiction potential is drawn, with comments on how preclinical models can inform on each. While the currently adopted preclinical models possess strong predictive validity, there are areas for future refinement and research. These areas include a more refined use of self-administration models to assess relative reinforcement; and the need for open innovation in pursuing improvements. There is also the need for careful scientifically driven application of models rather than a standardization of methodologies, and the need to explore the opportunities that may exist for enhancing the value of physical dependence and withdrawal studies by focusing on withdrawal-induced drug seeking, rather than broad symptomology.

    Background Substance use–related communication for drug use promotion and its prevention is widely prevalent on social media. Social media big data involve naturally occurring communication phenomena that are observable through social media platforms, which can be used in computational or scalable solutions to generate data-driven inferences. Despite the promising potential to utilize social media big data to monitor and treat substance use problems, the characteristics, mechanisms, and outcomes of substance use–related communications on social media are largely unknown. Understanding these aspects can help researchers effectively leverage social media big data and platforms for observation and health communication outreach for people with substance use problems. Objective The objective of this critical review was to determine how social media big data can be used to understand communication and behavioral patterns of problematic use of prescription drugs. We elaborate on theoretical applications, ethical challenges and methodological considerations when using social media big data for research on drug abuse and addiction. Based on a critical review process, we propose a typology with key initiatives to address the knowledge gap in the use of social media for research on prescription drug abuse and addiction. Methods First, we provided a narrative summary of the literature on drug use–related communication on social media. We also examined ethical considerations in the research processes of (1) social media big data mining, (2) subgroup or follow-up investigation, and (3) dissemination of social media data-driven findings. To develop a critical review-based typology, we searched the PubMed database and the entire e-collection theme of “infodemiology and infoveillance” in the Journal of Medical Internet Research / JMIR Publications.

    Lemieux, Andrine; al'Absi, Mustafa

    2016-01-01

    In this chapter, we briefly review the basic biology of psychological stress and the stress response. We propose that psychological stress and the neurobiology of the stress response play in substance use initiation, maintenance, and relapse. The proposed mechanisms for this include, on the one hand, the complex interactions between biological mediators of the stress response and the dopaminergic reward system and, on the other hand, mediators of the stress response and other systems crucial in moderating key addiction-related behaviors such as endogenous opioids, the sympathetic-adrenal-medullary system, and endocannabinoids. Exciting new avenues of study including genomics, sex as a moderator of the stress response, and behavioral addictions (gambling, hypersexuality, dysfunctional internet use, and food as an addictive substance) are also briefly presented within the context of stress as a moderator of the addictive process. © 2016 Elsevier B.V.

    2017-06-01

    The protein β -arrestin ( β arr) 2 directly interacts with receptors and signaling pathways that mediate the behavioral effects of drugs of abuse, making it a prime candidate for therapeutic interventions. β arr2 drives desensitization and internalization of G protein-coupled receptors, including dopamine, opioid, and cannabinoid receptors, and it can also trigger G protein-independent intracellular signaling. β arr2 mediates several drug-induced behaviors, but the relationship is complex and dependent on the type of behavior (e.g., psychomotor versus reward), the class of drug (e.g., psychostimulant versus opioid), and the circuit being interrogated (e.g., brain region, cell type, and specific receptor ligand). Here we discuss the current state of research concerning the contribution of β arr2 to the psychomotor and rewarding effects of addictive drugs. Next we identify key knowledge gaps and suggest new tools and approaches needed to further elucidate the neuroanatomical substrates and neurobiological mechanisms to explain how β arr2 modulates behavioral responses to drugs of abuse, as well as its potential as a therapeutic target.

    Sex differences are present for all of the phases of drug abuse (initiation, escalation of use, addiction, and relapse following abstinence). While there are some differences among specific classes of abused drugs, the general pattern of sex differences is the same for all drugs of abuse.

    The purpose of the current study was to evaluate possible overlapping substance abuse and internet addiction in a large, uniformly sampled population, ranging in age from 13 to 18 years. Participants (N=73,238) in the current study were drawn from the 6th Korea Youth Risk Behavior Web-based Survey (KYRBWS-V) for students from 400 middle schools and 400 high schools in 16 cities within South Korea. Of adolescent internet users, 85.2% were general users (GU), 11.9% were users with potential risk for internet addiction (PR), and 3.0% were users with high risk for internet addiction (HR). There was a difference in the number of students with alcohol drinking among the GU, PR, and HR groups (20.8% vs 23.1% vs 27.4%). There was a difference in the number of students who smoked among the GS, PR, and HR groups (11.7% vs 13.5% vs 20.4%). There was a difference in the number of students with drug use among the GU, PR, and HR groups (1.7% vs 2.0% vs 6.5%). After adjusting for sex, age, stress, depressed mood, and suicidal ideation, smoking may predict a high risk for internet addiction (OR=1.203, p=0.004). In addition, drug use may predict a high risk for internet addiction (OR=2.591, paddiction have vulnerability for addictive behaviors, co-morbid substance abuse should be evaluated and, if found, treated in adolescents with internet addiction.

    Child abuse is known to correlate with drug abuse and interferes with recovery from substance-related disorders. To determine the prevalence and severity of child abuse among drug addicts, we conducted a nationwide cross-sectional survey of residents and outpatients at drug addiction rehabilitation centers (DARC) in Japan. A total of 445 participants gave informed consent and completed a self-reporting questionnaire. Sixty-eight percent of participants had experienced some kind of child abuse by the time they reached junior high school. The kinds of abuse experienced were physical (53.7%), psychological (60.4%), sexual (5.4%) abuse and neglect (24.5%). Comparison of female and male participants revealed that more female than male participants had experienced psychological (76.9% vs. 58.2%) and sexual (17.5% vs. 4.0%) abuse. Comparison of participants who had experienced some kind of child abuse ("Abused" group 68.3%) and those who had not experienced abuse ("Non-abused" group 24.3%) revealed that the "Abused" group was younger than the "Non-abused" group (35.7 SD9.0 vs. 39.7 SD10.8). Participants in the "Abused" group were found to have more severe psychological difficulties than those in the "Non-abused" group for the following: anxiety (73.0% vs. 61.1%), delusional atmosphere (48.0% vs. 28.7%), lack of energy (53.9% vs. 40.7%), ideas of persecution (48.7% vs. 29.6%), depression (62.2% vs. 43.5%) and suicidal ideation in the previous year (50.7% vs. 24.3%). The present results suggest that additional program that prepared to care the drug addicts who experienced child abuse and are experiencing suicidal ideation is needed. Furthermore, intervention for families with risk factors for child abuse should be developed in order to prevent the victim from suffering not only from post traumatic stress disorder but also from substance related disorders.

  19. Sex differences in drug abuse.

    Science.gov (United States)

    Becker, Jill B; Hu, Ming

    2008-01-01

    Sex differences are present for all of the phases of drug abuse (initiation, escalation of use, addiction, and relapse following abstinence). While there are some differences among specific classes of abused drugs, the general pattern of sex differences is the same for all drugs of abuse. Females begin regularly self-administering licit and illicit drugs of abuse at lower doses than do males, use escalates more rapidly to addiction, and females are at greater risk for relapse following abstinence. In this review, sex differences in drug abuse are discussed for humans and in animal models. The possible neuroendocrine mechanisms mediating these sex differences are discussed.

    To describe the characteristics and health effects of adolescent (age 13-19 years) prescription drug abuse and misuse using the Researched Abuse Diversion and Addiction-Related Surveillance (RADARS(®)) System. Secondary analysis of data collected from RADARS System participating poison centers was performed. Data for all intentional exposures from 2007 through 2009 were used to describe adolescent prescription opioid (oxycodone, fentanyl, hydrocodone, hydromorphone, morphine, methadone, buprenorphine, and tramadol) and stimulant (methylphenidate and amphetamines) exposures. A total of 16,209 intentional adolescent exposures to prescription drugs were identified, 68% to opioids and 32% to stimulants. The mean age was 16.6 years (SD ± 1.7 years). Slightly more than half (52.4%) of drug mentions involved females. The five most frequently misused or abused drugs were hydrocodone (32%), amphetamines (18%), oxycodone (15%), methylphenidate (14%), and tramadol (11%). Of all exposures, 38% were classified as suspected suicidal. Of adolescents who intentionally exposed themselves to prescription drugs, 30% were treated in a health care facility, 2,792 of whom were admitted to the hospital, including 1,293 to the intensive care unit. A total of 17.2% of intentional exposures were associated with no effect, 38.9% minor effects, 23.3% moderate effects, 3.6% major effects, and 0.1% were associated with death. Oxycodone and methadone were associated with the most deaths. No deaths were associated with exposures to stimulants. Prescription drug misuse and abuse poses an important health problem and results in thousands of hospitalizations of adolescents per year. Further work is needed to develop focused interventions and educational programs to prevent prescription drug abuse and misuse by adolescents.

  3. Effects of drugs of abuse on hippocampal plasticity and hippocampus-dependent learning and memory: contributions to development and maintenance of addiction.

    Kutlu, Munir Gunes; Gould, Thomas J

    2016-10-01

    It has long been hypothesized that conditioning mechanisms play major roles in addiction. Specifically, the associations between rewarding properties of drugs of abuse and the drug context can contribute to future use and facilitate the transition from initial drug use into drug dependency. On the other hand, the self-medication hypothesis of drug abuse suggests that negative consequences of drug withdrawal result in relapse to drug use as an attempt to alleviate the negative symptoms. In this review, we explored these hypotheses and the involvement of the hippocampus in the development and maintenance of addiction to widely abused drugs such as cocaine, amphetamine, nicotine, alcohol, opiates, and cannabis. Studies suggest that initial exposure to stimulants (i.e., cocaine, nicotine, and amphetamine) and alcohol may enhance hippocampal function and, therefore, the formation of augmented drug-context associations that contribute to the development of addiction. In line with the self-medication hypothesis, withdrawal from stimulants, ethanol, and cannabis results in hippocampus-dependent learning and memory deficits, which suggest that an attempt to alleviate these deficits may contribute to relapse to drug use and maintenance of addiction. Interestingly, opiate withdrawal leads to enhancement of hippocampus-dependent learning and memory. Given that a conditioned aversion to drug context develops during opiate withdrawal, the cognitive enhancement in this case may result in the formation of an augmented association between withdrawal-induced aversion and withdrawal context. Therefore, individuals with opiate addiction may return to opiate use to avoid aversive symptoms triggered by the withdrawal context. Overall, the systematic examination of the role of the hippocampus in drug addiction may help to formulate a better understanding of addiction and underlying neural substrates. © 2016 Kutlu and Gould; Published by Cold Spring Harbor Laboratory Press.

    2013-04-01

    Lipidomics aims to identify and characterize all endogenous species of lipids and understand their roles in cellular signaling and, ultimately, the functioning of the organism. We are on the cusp of fully understanding the functions of many of the lipid signaling systems that have been identified for decades (e.g., steroids, prostaglandins), whereas our understanding of newer lipid signaling systems (e.g., endocannabinoids, N-acyl amides) still lags considerably behind. With an emphasis on their roles in the neurophysiology of addiction, we will examine three classes of lipids--sex steroids, prostaglandins, and cannabinoids--and how they work synergistically in the neurocircuitry of motivation. We will first give a brief overview of the biosynthesis for each class of lipid and its receptors, and then summarize what is known about the collective roles of the lipids in cocaine and alcohol abuse. This approach provides a novel view of lipid signaling as a class of molecules and their synergistic roles in addiction. © 2013 New York Academy of Sciences.

    Street-based prostitution accounts for 10% of the prostitution activity in Denmark, mainly involving female drug addicts. We studied a group of women with a common history of substance abuse and their comparative psychosocial characteristics, correlated with whether they had previously been a prostitute or not. Their psychic symptoms were evaluated and compared with those of controls. 27 females receiving maintenance treatment for substance abuse completed a questionnaire dealing with their social background, substance abuse profile, and history of sexual abuse and prostitution, as well as their current health status, including SCL-90. The scores were compared to those of a control group of an age- and gender-matched Danish standard population. Neglect in childhood and adulthood corresponded to international findings. 14 of the women had previous sex-trading experience, and early use of heroin and cocaine was a predictor for starting a career in prostitution. The SCL-90 scores for the dimensions of somatization and depression were significantly higher for drug-abusing women in general than in the control group. The scores of drug-abusing former prostitutes were similarly significantly higher on most of the dimensions except the hostility dimension when compared to those of drug-abusing women who had never been involved in prostitution. Rape and domestic violence were characteristic phenomena among drug-abusing prostitutes (p prostitution. Various psychosocial stress factors among street-based prostitutes indicate the need for broader psychiatric approaches in Danish drug addiction maintenance programmes.

    This paper reports that this study used SPECT to examine patients who have abused drugs to determine whether SPECT could identify abnormalities and whether these findings have clinical importance. Fifteen patients with a history of substance abuse (eight with cocaine, six with amphetamine, and one with organic solvent) underwent SPECT performed with a triple-headed camera and Tc-99m HMPAO both early for blood flow and later for functional information. These images were then processed into a 3D videotaped display used in group therapy. All 15 patients had multiple areas of decreased tracer uptake peppered throughout the cortex but mainly affecting the parietal lobes, expect for the organic solvent abuser who had a large parietal defect. The videotapes were subjectively described by a therapist as an exceptional tool that countered patient denial of physical damage from substance abuse.

    2011-09-01

    This discussion piece suggests that reliance on a Higher Power in drug abuse recovery programs is entertained among some addicts for its psychobiological effects. Prayer, meditation, early romantic love, and drug abuse may have in common activation of mesolimbic dopaminergic pathways of the brain and the generation of intense emotional states. In this sense, reliance on a Higher Power may operate as a substitute addiction, which replaces the psychobiological functions formerly served by drug use. Implications of this perspective are discussed.

    Pregabalin is a novel GABA-analogue approved for the treatment of partial onset seizures, neuropathic pain, and general anxiety disorder. Pregabalin has been classified as a Schedule V drug with a low risk of inflicting abuse or addiction. However, some publications have indicated that pregabalin may have a potential for abuse among patients with past or current opiate addiction. Thus, we hypothesized that pregabalin might be abused by patients who were undergoing an opiate replacement therapy and never had an indication for taking pregabalin on medical grounds. Urine specimens from 124 patients with opiate dependency syndrome and from 111 patients with other addiction disorders (alcohol, benzodiazepines, cannabis, amphetamines) were screened for pregabalin by means of a mass spectrometer analysis. We found 12.1 % of all urine specimens from patients with opiate addiction to be positive for pregabalin. None of the patients concerned had a medical indication for using pregabalin. In the control group, 2.7 % of the patients were tested positively for pregabalin, due to their taking it regularly for chronic pain or general anxiety. Our data suggest that pregabalin is liable to be abused among individuals with opiate dependency syndrome Thus, vigilance and caution are called for when patients with a past or current opiate dependency are exposed to treatment with pregabalin.

  13. Addiction and substance abuse in anesthesiology.

    Bryson, Ethan O; Silverstein, Jeffrey H

    2008-11-01

    Despite substantial advances in our understanding of addiction and the technology and therapeutic approaches used to fight this disease, addiction still remains a major issue in the anesthesia workplace, and outcomes have not appreciably changed. Although alcoholism and other forms of impairment, such as addiction to other substances and mental illness, impact anesthesiologists at rates similar to those in other professions, as recently as 2005, the drug of choice for anesthesiologists entering treatment was still an opioid. There exists a considerable association between chemical dependence and other psychopathology, and successful treatment for addiction is less likely when comorbid psychopathology is not treated. Individuals under evaluation or treatment for substance abuse should have an evaluation with subsequent management of comorbid psychiatric conditions. Participation in self-help groups is still considered a vital component in the therapy of the impaired physician, along with regular monitoring if the anesthesiologist wishes to attempt reentry into clinical practice.

    2015-08-01

    General anesthetics (GA) are well known for the ability to induce a state of reversible loss of consciousness and unresponsiveness to painful stimuli. However, evidence from animal models and clinical studies show that GA exposure may induce behavioral changes beyond acute effects. Most research and concerns are focused on changes in cognition and memory. We will look at effects of GA on behavior that is mediated by the dopaminergic system. Pharmacological resemblance of GA with drugs of abuse, and the complexity and importance of dopaminergic systems in both reward seeking and addictive illnesses make us believe that it deserves an overview about what is already known and what matters to us as healthcare workers and specifically as anesthesiologists. A review of available evidence strongly suggests that there may be a link between the effects of GA on the brain and substance abuse, partly explained by their influence on the dopaminergic system. © 2015 The Acta Anaesthesiologica Scandinavica Foundation.

    Addiction to illicit drugs in one of today's most important social issues. Most addictive drugs lead to irreversible parenchymal changes in the human brain. Neuroimaging data bring to light the pharmacodynamics and pharmacokinetics of the abused drugs, and demonstrate that addiction is a disease of the brain. Continuous researches better illustrate the neurochemical alterations in brain function, and attempt to discover the links to consequent behavioral changes. Newer hypotheses and theories follow the numerous results, and more rational methods of approaching therapy are being developed. Substance abuse is on the rise in Korea, and social interest in the matter as well. On the other hand, diagnosis and treatment of drug addiction is still very difficult, because how the abused substance acts in the brain, or how it leads to behavioral problems in not widely known. Therefore, understanding the mechanism of drug addiction can improve the process of diagnosing addict patients, planning therapy, and predicting the prognosis . Neuroimaging approaches by nuclear medicine methods are expected to objectively judge behavioral and neurochemical changes, and response to treatment. In addition, as genes associated with addictive behavior are discovered, functional nuclear medicine images will aid in the assessment of individuals. Reviewing published literature on neuroimaging regarding nuclear medicine is expected to be of assistance to the management of drug addict patients. What's more, means of applying nuclear medicine to the care of drug addict patients should be investigated further.

The effect of drugs leaves permanent consequences on the brain, organic in type, followed by numerous manifestations, and it significantly affects the development of mental dysfunctions. The clinicians are often given a task to estimate a patient’s personality during treatment or during experts estimate of a drug addict. The aim of this research was to determine the differences, if any, in characteristics of addicts experience and personality traits in drug addicts with or without cerebral edema. Methods. The research was conducted on a sample of 252 male drug addicts, the average age of 23.3 (SD = 4.3 years. Cerebral edema was confirmed on magnetic resonance (MR images of the brain performed during the treatment of the addicts. The participants were tested by the psychologists using Minnesota Multiphasic Personality Inventory (MMPI-201 test, and the data were processed using canonical discriminate analysis within the SPSS program. The dependent variable in the study was cerebral edema. A block of independent variables, designed for the requirements of this study, consisted of two subgroups. The first one consisted of 12 variables describing the relevant characteristics of drug abuse. The second subgroup consisted of 8 psychopathological tendencies in the personality defined by the mentioned test. Results. Cerebral edema was confirmed in 52 (20.63% of the drug addicts. The differences between the groups of drug addicts with and without cerebral edema were determined in the following: the time span of taking drugs (0.301, use of alcohol parallel with drugs (0.466, and treatment for addiction (0.603. In the drug addicts with a cerebral edema, MMPI-201 confirmed the increase in the scales for hypochondria, psychopathic deviations and psychastenia, and the decrease in the scales for schizophrenia and depression. Conclusion. Our study confirmed a possible connection between cerebral edema and personality traits in a number of the

    Full Text Available ABSTRACT:Drug abuse is the willful misuse of either licit or illicit drugs for the purpose of recreation, perceived necessity or convenience. Drug abuse is a more intense and often willful misuse of drugs often to the point of addiction. In the eastern world the incidence shows a decline or a static pattern but the number of drug addicts is still enormous.. The major drug of abuse are heroin and marijuana but designer drugs are shown to be on the increase. The aim of the study is to determine the ratio of the drug abuse in student. For this purpose we selected different institutions including “the university of Lahore”, “Forman Christian college”(private sector and Punjab university(Govt sector and conducted survey in 500 student. High proportion of students was found abusing drugs. From this study, we came across multiple factors which are the main cause of drug abuse in medical student including depression, anxiety, schizophrenia, as well as personality disorder like antisocial personality disorder. The most commonly abused drugs include stimulants, opioids, and benzodiazepines, antihistamines. Although survey have indicated high rate of illicit and prescription drugs misuse among college students, few have assessed the negative consequences, personel concerns, or interest in intervention for drugs use. Drug abuse although regarded as a personality disorder, may also be seen as worldwide epidemic with evolutionary genetic, physiology and environmental influences Controlling and affecting human behavior. Globally, the use has reached all time high. The study showed males are more drug abusers as compared to females. The drug abuse ratio in students of private sector is more as compared to Govt sector.

    2002-10-01

    The goals of present article are three – fold: In the first step, it introduces a brief form of motivational Interviewing for addictive behaviors. Its primary basis is the idea that most substance abusers seek medical treatment without being ready to change addictive behaviors. As a result, attempts the addicts to change often lead to their resistance. Therefore, the use of motivational interviewing (MI in which clients are directed towards realizing their own reasons and arguments for changing their behavior, seems to be most oppropriate to motivate and prepare them for change. In the second step, the article tries to discuss advantages of motivational interviewing approach to often opproaches (e.g, skills training approach, Indirect approach and confrontational – denial approach and suggests that (MI is the most appropriate strategy for the substance abusers, according to their degree of readiness for change. Finally in the third step, the article attempts to indicate the current dominant strategies of addiction treatment in Iran and concludes that due to dominance and commonality of medicine – based treatment strategies of addictive behaviors, (MI could be introduced as an alternative and appropriate treatment strategy for drug addicts in Iran.

  1. New drugs of abuse.

    2015-02-01

    Drug abuse is a common problem and growing concern in the United States, and over the past decade, novel or atypical drugs have emerged and have become increasingly popular. Recognition and treatment of new drugs of abuse pose many challenges for health care providers due to lack of quantitative reporting and routine surveillance, and the difficulty of detection in routine blood and urine analyses. Furthermore, street manufacturers are able to rapidly adapt and develop new synthetic isolates of older drugs as soon as law enforcement agencies render them illegal. In this article, we describe the clinical and adverse effects and purported pharmacology of several new classes of drugs of abuse including synthetic cannabinoids, synthetic cathinones, salvia, desomorphine, and kratom. Because many of these substances can have severe or life-threatening adverse effects, knowledge of general toxicology is key in recognizing acute intoxication and overdose; however, typical toxidromes (e.g., cholinergic, sympathomimetic, opioid, etc.) are not precipitated by many of these agents. Medical management of patients who abuse or overdose on these drugs largely consists of supportive care, although naloxone may be used as an antidote for desomorphine overdose. Symptoms of aggression and psychosis may be treated with sedation (benzodiazepines, propofol) and antipsychotics (haloperidol or atypical agents such as quetiapine or ziprasidone). Other facets of management to consider include treatment for withdrawal or addiction, nutrition support, and potential for transmission of infectious diseases. © 2014 Pharmacotherapy Publications, Inc.

    Newman, Michelle G; Szkodny, Lauren E; Llera, Sandra J; Przeworski, Amy

    2011-02-01

    Technology-based self-help and minimal contact therapies have been proposed as effective and low-cost interventions for addictive disorders, such as nicotine, alcohol, and drug abuse and addiction. The present article reviews the literature published before 2010 on computerized treatments for drug and alcohol abuse and dependence and smoking addiction. Treatment studies are examined by disorder as well as amount of therapist contact, ranging from self-administered therapy and predominantly self-help interventions to minimal contact therapy where the therapist is actively involved in treatment but to a lesser degree than traditional therapy and predominantly therapist-administered treatments involving regular contact with a therapist for a typical number of sessions. In the treatment of substance use and abuse it is concluded that self-administered and predominantly self-help computer-based cognitive and behavioral interventions are efficacious, but some therapist contact is important for greater and more sustained reductions in addictive behavior.

    Winger, Gail; Woods, James H.; Galuska, Chad M.; Wade-Galuska, Tammy

    2005-01-01

    Neuroscientific approaches to drug addiction traditionally have been based on the premise that addiction is a process that results from brain changes that in turn result from chronic administration of drugs of abuse. An alternative approach views drug addiction as a behavioral disorder in which drugs function as preeminent reinforcers. Although…

  5. Cannabinoid-1 receptor (CB1R) blockers as medicines: beyond obesity and cardiometabolic disorders to substance abuse/drug addiction with CB1R neutral antagonists.

    Science.gov (United States)

    Janero, David R

    2012-03-01

    Addiction to chemical substances with abuse potential presents medical needs largely unsolved by extant therapeutic strategies. Signal transmission through the cannabinoid-1 receptor (CB1R) in the central nervous system (CNS) modulates neurotransmitters/neuronal pathways contributing to the rewarding properties and hedonic effects of certain nondrug stimuli (e.g., food) and many prototypical addictive drugs, promoting excessive intake and its pathological consequences. Typical CB1R antagonists/inverse agonists reduce the rewarding effects and normalize behavioral phenotypes associated with food and abused drugs, but carry an unacceptable adverse-event profile that may reflect, at least partly, their intrinsic ability to alter basal homeostatic CB1R signaling in the CNS and elicit a negative efficacy response. Alternatively, peripherally biased CB1R inverse agonists with limited CNS permeability and putative CB1R neutral antagonists expressing modest (if any) inverse-agonist efficacy are garnering attention for treating obesity and related cardiometabolic complications with a potentially enhanced benefit-to-risk profile. This mini-review calls attention to the proposition that CB1R neutral antagonists offer attractive opportunities for pharmacotherapeutic exploitation in the substance abuse/drug addiction space, whereas the restricted CNS accessibility of peripherally biased CB1R inverse agonists circumscribes their therapeutic utility for this indication. The unique preclinical pharmacology, efficacy profiles, and reduced adverse-event risk of CB1R neutral antagonists make them worthy of translational study for their potential therapeutic application beyond obesity/cardiometabolic disease to include substance-abuse/drug-addiction disorders.

    "Krokodil" is the street name for the semi-synthetic opioid derivative desomorphine. Although an old drug, it re-staged on "drug arena" during the last decade causing detrimental effects to its users. Despite the fact that Russia and other former Soviet Republics were the initial plagued countries, "krokodil" arrived in Europe and United States lately, as a substitute of the relative expensive, and in many cases unavailable, heroin. It can be easily manufactured in home-environment from codeine and causes significant health problems, even deaths worldwide. The aim of this review is to summarize the current knowledge about this drug, concerning its chemistry, synthesis, pharmacology and toxicology. Published or reported "krokodil" related cases, fatalities or intoxications, as well as self reports from drug users are reviewed. The existing analytical methodologies for the determination of desomorphine in biological samples as well as its legal status are also presented. Copyright © 2014 Elsevier Inc. All rights reserved.

    One of the most effective strategies in the prevention of addiction is increasing awareness among young people, towards the tendency for taking drugs their physical, mental and social side effects. Storytelling is effective for increasing characteristics of happiness and resilience. This study uses storytelling, a common and popular method to increase awareness among adolescents. To examine the effect of storytelling-based education on the prevention of drug abuse, based on a readiness to addiction index. This quasi-experimental study was conducted on 136 high school students (grade one), selected by a cluster sampling procedure from May 2014 to February 2015 in Zabol, Iran. The instrument for gathering data was a readiness to addiction questionnaire. This questionnaire included 41 items for which the scoring of each item followed the Likerts format. The data gathered was analysed using SPSS version 21 with descriptive statistics and inferential statistics. The results revealed that the mean of the readiness to addiction index in the case group fell from 75.66±19.99 to 69.57±21.83 (paired t-test; p =0.02); in the control group the same index changed from 103.01±21.88 to 93.98±27.70 (paired t-test, p = 0.775). That is, the index decreased for both groups, but the reduction was statistically significant only for the case group (p =0.02). This suggests that the narrative method is effective in reducing adolescents readiness to addiction. Storytelling is an effective way to raise awareness among young people about addiction and its detrimental impacts on health. Therefore, such a technique can be taken into consideration in teaching principles of prevention.

  16. Substance Abuse in Addicts Referred to Public and Private Substance Abuse Treatment Centers

    Directory of Open Access Journals (Sweden)

    Kadkhodaei M.* MSc,

    2015-06-01

    Full Text Available Aims Drug addiction is a mental, social, and economic problem that comes from abnormal and illicit consumption of substances such as alcohol, opium, hashish, and etc., making the addict psychologically and physiologically dependent to those substances. This study was designed and performed to evaluate the pattern of drug abuse change in the addicts visiting addiction treatment centers of Kashan City, Iran. Instrument & Methods This retrospective descriptive research was performed on 4066 persons referred to addiction treatment and harm reduction therapy centers, monitored by Kashan University of Medical Sciences, during 2004 to 2008. After coding, data were entered into the SPSS 16 software. Chi-square and one-way ANOVA was used to analyze the data. Findings The main reasons of the tendency to drugs were not having fun (72.5%, family problems (55% and not having knowledge (22.7%. The use of opium was the highest in all the years while the crack was used by 7.1% of drug addicts in 2004 and increased to 76% in 2007. 92.8% of drug abuses were through fumigation, 33.7% through injection, 48% orally and 8.6% through inhalants. Conclusion Youths are the most vulnerable age group to drug addiction. Easy access to illegal drugs, wrong friends, and curiosity are of the significant factors spreading drug addiction.

    This article attempts to review the most current and the well-established facts concerning drug addiction and sexual dysfunction. Surprisingly, even though alcohol is prevalent in many societies with many myths surrounding its sexual-enhancing effects, current scientific research cannot provide a solid conclusion on its effect on sexual function. Unfortunately, the same concept applies to tobacco smoking; however, most of the current knowledge tends to support the notion that it, indeed, can negatively affect sexual function. Similar ambiguities also prevail with substances of abuse. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Richard B FrancoeurSchool of Social Work, Adelphi University, Garden City, NY, USA; Center for the Psychosocial Study of Health and Illness, Columbia University, New York, NY, USAAbstract: This article proposes and develops novel components of community-oriented programs for creating and affording access to safe medication dispensing centers in existing retail pharmacies and in permanent or travelling pharmacy clinics that are guarded by assigned or off-duty police officers. Pharmacists at these centers would work with police, medical providers, social workers, hospital administrators, and other professionals in: planning and overseeing the safe storage of controlled substance medications in off-site community safe-deposit boxes; strengthening communication and cooperation with the prescribing medical provider; assisting the prescribing medical provider in patient monitoring (checking the state prescription registry, providing pill counts and urine samples; expanding access to lower-cost, and in some cases, abuse-resistant formulations of controlled substance medications; improving transportation access for underserved patients and caregivers to obtain prescriptions; and integrating community agencies and social networks as resources for patient support and monitoring. Novel components of two related community-oriented programs, which may be hosted outside of safe medication dispensing centers, are also suggested and described: (1 developing medication purchasing cooperatives (ie, to help patients, families, and health institutions afford the costs of medications, including tamper- or abuse-resistant/deterrent drug formulations; and (2 expanding the role of inner-city methadone maintenance treatment programs in palliative care (ie, to provide additional patient monitoring from a second treatment team focusing on narcotics addiction, and potentially, to serve as an untapped source of opioid medication for pain that is less subject to abuse

    Individuals addicted to drugs of abuse such as alcohol, nicotine, cocaine, and heroin are a significant burden on healthcare systems all over the world. The positive reinforcing (rewarding) effects of the above mentioned drugs play a major role in the initiation and maintenance of the drug-taking habit. Thus, understanding the neurochemical mechanisms underlying the reinforcing effects of drugs of abuse is critical to reducing the burden of drug addiction in society. Over the last two decades, there has been an increasing focus on the role of the excitatory neurotransmitter glutamate in drug addiction. In this review, pharmacological and genetic evidence supporting the role of glutamate in mediating the rewarding effects of the above described drugs of abuse will be discussed. Further, the review will discuss the role of glutamate transmission in two complex heterogeneous brain regions, namely the nucleus accumbens (NAcc) and the ventral tegmental area (VTA), which mediate the rewarding effects of drugs of abuse. In addition, several medications approved by the Food and Drug Administration that act by blocking glutamate transmission will be discussed in the context of drug reward. Finally, this review will discuss future studies needed to address currently unanswered gaps in knowledge, which will further elucidate the role of glutamate in the rewarding effects of drugs of abuse.

  6. Cannabis abuse and addiction: a contemporary literature review.

    Science.gov (United States)

    Iyalomhe, G B S

    2009-01-01

    Drug addiction, particularly among teenagers and young adults, has become a serious public health problem globally. Drugs with addictive potential include the non-therapeutic drugs that are licit/legal (caffeine, tobacco or nicotine, alcohol) and those that are illegal/illicit for common use such as benzodiazepines, amphetamines, cocaine and crack, heroin and cannabis. Worldwide, the challenge of cannabis abuse and addiction is particularly devastating, nay in Nigeria. Despite this ugly scenario, the use of cannabis continues unabated and its control remains enigmatic. The aim of the present review is to provide a contemporary comprehensible overview of exciting recent developments in the understanding of brain circuits related to the nature and effects of cannabis abuse and addiction as well as to highlight the current therapeutic approach to effective management. A thorough manual literature and internet (Medline and HINARI databases) search were conducted. It was found that recent advances in the neurobiology of drug abuse and addiction have led to the identification of neuronal substrates (eg dopamine, 5-hydroxyltrypytamine etc) as being responsible for the rewarding effects of cannabis and are also crucial to the addictive process/behaviour. There is increasing evidence that prolonged exposure to drugs of abuse including cannabis, produces long-lasting effects in cognitive and drug-rewarding brain circuits. Hence, addiction is now generally considered a chronic brain disease. Chronic use of cannabis impairs cognitive functions, perception, reaction time, learning, memory, concentration, social skills and control of emotions. There may also be panic reactions, hallucinations, paranoid states with fixed delusions and even acute psychosis. These impairments have obvious negative implications for the operation of a motor vehicle or machinery and performance at school or workplace as well as the development of a healthy family, a strong national economy and a

    Being the center of energy production in eukaryotic cells, mitochondria are also crucial for various cellular processes including intracellular Ca(2+) signaling and generation of reactive oxygen species (ROS). Mitochondria contain their own circular DNA which encodes not only proteins, transfer RNA and ribosomal RNAs but also non-coding RNAs. The most recent line of evidence indicates the presence of 5-methylcytosine and 5-hydroxymethylcytosine in mitochondrial DNA (mtDNA); thus, the level of gene expression - in a way similar to nuclear DNA - can be regulated by direct epigenetic modifications. Up to now, very little data shows the possibility of epigenetic regulation of mtDNA. Mitochondria and mtDNA are particularly important in the nervous system and may participate in the initiation of drug addiction. In fact, some addictive drugs enhance ROS production and generate oxidative stress that in turn alters mitochondrial and nuclear gene expression. This review summarizes recent findings on mitochondrial function, mtDNA copy number and epigenetics in drug addiction. Copyright © 2014 Elsevier Inc. All rights reserved.

    2011-12-01

    An essential feature of drug addiction is that an individual continues to use drug despite the threat of severely adverse physical or psychosocial consequences. Persistent changes in behavior and psychological function that occur as a function of drugs of abuse are thought to be due to the reorganization of synaptic connections (structural plasticity) in relevant brain circuits (especially the brains reward circuits). In this paper we summarized evidence that, indeed, exposure to amphetamine, cocaine, nicotine or morphine produced persistent changes in the structure of dendrites and dendritic spines on cells in relevant brain regions. We also approached the potential molecular mechanisms of these changes. It is suggested that structural plasticity associated with exposure to drugs of abuse reflects a reorganization of patterns of synaptic connectivity in these neural systems, a reorganization that alters their operation, thus contributing to some of the persistent sequela associated with drug use-including addiction.

    Opioid drug abuse and dependence/addiction are complex disorders regulated by a wide range of interacting networks of genes and pathways that control a variety of phenotypes. Although the field has been extensively progressed since the birth of the National Institute on Drug Abuse in 1974, the fundamental knowledge and involved mechanisms that lead to drug dependence/addiction are poorly understood, and thus, there has been limited success in the prevention of drug addiction and development of therapeutics for definitive treatment and cure of addiction disease. The lack of success in both identification of addiction in at-risk populations and the development of efficient drugs has resulted in a serious social and economic burden from opioid drug abuse with global increasing rate of mortality from drug overdoses. This perspective aims to draw the attention of scientists to the potential role of nanotechnologies, which might pave the way for the development of more practical platforms for either drug development or identification and screening of patients who may be vulnerable to addiction after using opioid drugs.

    Science.gov (United States)

    Maldonado, R

    2010-01-01

    Drug addiction is a chronic brain disorder leading to complex adaptive changes within the brain reward circuits. Several neurotransmitters, including the endogenous opioid system are involved in these changes. The opioid system plays a pivotal role in different aspects of addiction. Thus, opioid receptors and endogenous opioid peptides are largely distributed in the mesolimbic system and modulate dopaminergic activity within the reward circuits. Opioid receptors and peptides are selectively involved in several components of the addictive processes induced by opioids, cannabinoids, psychostimulants, alcohol and nicotine. This review is focused on the contribution of each component of the endogenous opioid system in the addictive properties of the different drugs of abuse. Copyright 2010 Elsevier Masson SAS.

  17. Natural Rewards, Neuroplasticity, and Non-Drug Addictions

    Science.gov (United States)

    Olsen, Christopher M.

    2011-01-01

    There is a high degree of overlap between brain regions involved in processing natural rewards and drugs of abuse. “Non-drug” or “behavioral” addictions have become increasingly documented in the clinic, and pathologies include compulsive activities such as shopping, eating, exercising, sexual behavior, and gambling. Like drug addiction, non-drug addictions manifest in symptoms including craving, impaired control over the behavior, tolerance, withdrawal, and high rates of relapse. These alterations in behavior suggest that plasticity may be occurring in brain regions associated with drug addiction. In this review, I summarize data demonstrating that exposure to non-drug rewards can alter neural plasticity in regions of the brain that are affected by drugs of abuse. Research suggests that there are several similarities between neuroplasticity induced by natural and drug rewards and that, depending on the reward, repeated exposure to natural rewards might induce neuroplasticity that either promotes or counteracts addictive behavior.

    On January 1, 1997, as the result of federal legislation, many low-income substance abusers lost income and healthcare benefits provided by the Supplemental Security Income (SSI) program. This study examined the effects of eliminating drug addiction and alcoholism (DAA) as qualifying impairments for SSI benefits on the mental health and mental health treatment utilization of former beneficiaries 3.5 years following the policy change. Study participants in four Northern California counties were categorized into three comparison groups based on their primary income source over the lifetime of the study. Findings indicated that overall the reported mental health status of former SSI DAA beneficiaries improved following the policy change; however, study participants who relied primarily on some other type of public assistance post-termination reported an increase in mental health treatment utilization.

    2014-02-01

    The incidence of drug abuse with alternative agents is increasing. The term "alternative drugs of abuse" is a catch-all term for abused chemicals that do not fit into one of the classic categories of drugs of abuse. The most common age group abusing these agents range from 17 to 25 years old and are often associated with group settings. Due to their diverse pharmacological nature, legislative efforts to classify these chemicals as a schedule I drug have lagged behind the development of new alternative agents. The potential reason for abuse of these agents is their hallucinogenic, dissociative, stimulant, anti-muscarinic, or sedative properties. Some of these drugs are easily obtainable such as Datura stramonium (Jimson Weed) or Lophophora williamsii (Peyote) because they are natural plants indigenous to certain regions. The diverse pharmacology and clinical effects of these agents are so broad that they do not produce a universal constellation of signs and symptoms. Detailed physical exams are essential for identifying clues leading one to suspect an alternative drug of abuse. Testing for the presence of these agents is often limited, and even when available, the results do not return in a timely fashion. Intoxications from these agents pose unique challenges for health care providers. Physician knowledge of the physiological effects of these alternative agents and the local patterns of drug of abuse are important for the accurate diagnosis and optimal care of poisoned patients. This review summarizes the current knowledge of alternative drugs of abuse and highlights their clinical presentations.

    Destitute drug addicts have not deliberately chosen to be socially excluded; it's more the consequence of a sanitary and social policy which has given a greater importance to the treatment of addiction than to the drug addict's health. Facing Aids, physicians, with their pragmatic attitude, have reversed this drift. On the streets, the drug addict holds handicaps concurrently; medicinal addiction leads to harder sevrance and substitution. Having access to social rights allows to regain an identity, compulsory for an access to health care; but public hospitals have to make casier both the admission and the stay of patients whose therapeutic observance is dependent on a preliminary substitution. Drug addiction and precarity represent a double social challenge that a democratic society must take up without any segregation.

    The use of recreational drugs of abuse continues to expand without limitations to national boundaries, social status, race, or education. Beyond the prevalence of illicit drug use and dependence, their contribution to the global burden of disease and death are large and troubling. All medical providers should be aware of the evolving drugs of abuse and their medical and social consequences. In addition to heroin and stimulants such as cocaine and methamphetamine, new designer stimulants called "bath salts" and cannabinoids called "spice," along with the abuse of prescription drugs and volatile substances, are now widely recognized problems in many societies. The wide variety and continuingly expanding clinical manifestations of toxicity of recreational drugs of abuse is not widely appreciated by clinicians. This edition attempts to summarize six major classes of drugs of abuse and their clinical effects with special emphasis on their immunological and respiratory effects.

    Parental substance use is a major risk factor for child development, heightening the risk of drug problems in adolescence and young adulthood, and exposing offspring to several types of traumatic events. First, prenatal drug exposure can be considered a form of trauma itself, with subtle but long-lasting sequelae at the neuro-behavioral level. Second, parents' addiction often entails a childrearing environment characterized by poor parenting skills, disadvantaged contexts and adverse childhood experiences (ACEs), leading to dysfunctional outcomes. Young adults born from/raised by parents with drug problems and diagnosed with a Substance Used Disorder (SUD) themselves might display a particularly severe condition in terms of cognitive deficits and impaired personality function. This preliminary study aims to investigate the role of early exposure to drugs as a traumatic event, capable of affecting the psychological status of young drug addicts. In particular, it intends to examine the neuropsychological functioning and personality profile of young adults with severe SUDs who were exposed to drugs early in their family context. The research involved three groups, each consisting of 15 young adults (aged 18-24): a group of inpatients diagnosed with SUDs and exposed to drugs early, a comparison group of non-exposed inpatients and a group of non-exposed youth without SUDs. A neuropsychological battery (Esame Neuropsicologico Breve-2), an assessment procedure for personality disorders (Shedler-Westen Assessment Procedure-200) and the Symptom CheckList-90-Revised were administered. According to present preliminary results, young drug addicts exposed to drugs during their developmental age were characterized by elevated rates of neuropsychological impairments, especially at the expense of attentive and executive functions (EF); personality disorders were also common but did not differentiate them from non-exposed youth with SUDs.

    Full Text Available Abstract Background The epidemiological significance of Hepatitis B virus genotypes has been well established and becoming an essential concern day by day however, much little is known about the mixed infection with more than one Hepatitis B virus genotypes and their clinical relevance. Methods Intravenous drug abusers are considered as a major risk group for the acquisition and transmission of blood borne infections like hepatitis B, however, in Pakistan, no such data has ever been reported about the epidemiology of HBV and its genotypes in Injecting Drug Users. 250 individuals were analyzed for hepatitis B virus genotypes after prior screening with serological assay for the detection of HBsAg. Results 56 (22.4% individuals were found positive on ELSIA for HBsAg. The genotype distribution was found to be as: genotype D, 62.5%; genotype A, 8.92% while 28.57% individuals were found to be infected with a mixture of genotype A and D. Conclusion There is an urgent need of the time to develop public health care policies with special emphasis towards the control of HBV transmission through high risk groups especially Injecting Drug Users.

    Full Text Available Objectives: There are researches to point epidemiology of addiction to drugs, chemical and solvent abuse in elderlies. Drug and Solvent abuse is considered as one of these addictions. This study was point to chemical abuse among elderly population of Ahwaz an Iranian city during year of 2007. Methods & Materials: Research method is description-exploration with use to questionnaire, clinical interview and survey of medical and clinical reports among volunteer clients. Statistical community is all elderly population at one of citizen region in Ahwaz city (Iran. Seventy four dossiers were considered via random sampling; with 30 Elder volunteer clients been interviewed and replied to Elderly Drug Abuse Questionnaire (EDAQ. Results: Signification of hypothesis with X2 test was considered significant relation between age and addiction record variables to solvent abuse; this relation is very significant to second value of drug's derivations such as Morphine, Codeine, Tebaine and Heroine. Interview showed psychological dependent due to appeal them to solvent abuse. Kind of abuse among elderly was snuffing and abuse of medicine drugs which were been recommended to them by their physician. Conclusion: Although study of solvent and chemical abuse's epidemiology pointed less average of this addiction in samples, should be considered important and notice in studies. Finally, researchers were suggested to avoid of this new drug abuse and so to control behavior and interaction of these addicted and their behavior development; it's better to control on distribution of solvent and glue materials and recommending of medicine drug via physicians visiting exderlies.

    This article proposes and develops novel components of community-oriented programs for creating and affording access to safe medication dispensing centers in existing retail pharmacies and in permanent or travelling pharmacy clinics that are guarded by assigned or off-duty police officers. Pharmacists at these centers would work with police, medical providers, social workers, hospital administrators, and other professionals in: planning and overseeing the safe storage of controlled substance medications in off-site community safe-deposit boxes; strengthening communication and cooperation with the prescribing medical provider; assisting the prescribing medical provider in patient monitoring (checking the state prescription registry, providing pill counts and urine samples); expanding access to lower-cost, and in some cases, abuse-resistant formulations of controlled substance medications; improving transportation access for underserved patients and caregivers to obtain prescriptions; and integrating community agencies and social networks as resources for patient support and monitoring. Novel components of two related community-oriented programs, which may be hosted outside of safe medication dispensing centers, are also suggested and described: (1) developing medication purchasing cooperatives (ie, to help patients, families, and health institutions afford the costs of medications, including tamper-or abuse-resistant/deterrent drug formulations); and (2) expanding the role of inner-city methadone maintenance treatment programs in palliative care (ie, to provide additional patient monitoring from a second treatment team focusing on narcotics addiction, and potentially, to serve as an untapped source of opioid medication for pain that is less subject to abuse, misuse, or diversion).

    Despite the growing prevalence of prescription opioid dependence, longitudinal studies have not examined long-term treatment response. The current study examined outcomes over 42 months in the Prescription Opioid Addiction Treatment Study (POATS). POATS was a multi-site clinical trial lasting up to 9 months, examining different durations of buprenorphine-naloxone plus standard medical management for prescription opioid dependence, with participants randomized to receive or not receive additional opioid drug counseling. A subset of participants (N=375 of 653) enrolled in a follow-up study. Telephone interviews were administered approximately 18, 30, and 42 months after main-trial enrollment. Comparison of baseline characteristics by follow-up participation suggested few differences. At Month 42, much improvement was seen: 31.7% were abstinent from opioids and not on agonist therapy; 29.4% were receiving opioid agonist therapy, but met no symptom criteria for current opioid dependence; 7.5% were using illicit opioids while on agonist therapy; and the remaining 31.4% were using opioids without agonist therapy. Participants reporting a lifetime history of heroin use at baseline were more likely to meet DSM-IV criteria for opioid dependence at Month 42 (OR=4.56, 95% CI=1.29-16.04, popioid abstinence. Eight percent (n=27/338) used heroin for the first time during follow-up; 10.1% reported first-time injection heroin use. Long-term outcomes for those dependent on prescription opioids demonstrated clear improvement from baseline. However, a subset exhibited a worsening course, by initiating heroin use and/or injection opioid use. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Drug addiction is present in a significant proportion of the population in the USA and worldwide. Drug addiction can occur with the abuse of many types of substances including cocaine, marijuana, stimulants, alcohol, opioids, and tranquilizers. There is a high likelihood that clinicians will encounter patients with substance abuse disorders on a regular basis with the prevalence of the use of illicit substances and the high rate of abuse of prescription drugs. The use of abuse deterrent formulations of prescription opioid agents, pill counts, and urine drug abuse screenings are all useful strategies. Optimum pain management of patients with addiction in the outpatient and inpatient setting is essential to minimize pain states. Careful selection of medications and appropriate oversight, including drug agreements, can reduce drug-induced impairments, including sleep deficits and diminished physical, social, and sexual functioning. This review, therefore, discusses the prevalence of illicit and prescription drug addiction, the challenges of achieving optimum pain control, and the therapeutic approaches to be considered in this challenging population. More research is warranted to develop improved therapies and routes of treatments for optimum pain relief and to prevent the development of central sensitization, chronic pain, and impaired physical and social functioning in patients with drug addiction.

    Drug addiction places a significant burden on society and individuals. Proteomics and metabolomics approaches pave the road for searching potential biomarkers to assist the diagnosis and treatment. This review summarized putative drug addiction-related biomarkers in proteomics and metabolomics studies and discussed challenges and prospects in future studies. Alterations of several hundred proteins and metabolites were reported when exposure to abused drug, which enriched in energy metabolism, oxidative stress response, protein modification and degradation, synaptic function and neurotrasmission, etc. Hsp70, peroxiredoxin-6 and α- and β-synuclein, as well as n-methylserotonin and purine metabolites, were promising as potential biomarker for drug addiction.

    Many new emerging drugs of abuse are marketed as legal highs despite being labeled "not for human consumption" to avoid regulation. The availability of these substances over the Internet and in "head shops" has lead to a multitude of emergency department visits with severe complications including deaths worldwide. Despite recent media attention, many of the newer drugs of abuse are still largely unknown by health care providers. Slight alterations of the basic chemical structure of substances create an entirely new drug no longer regulated by current laws and an ever-changing landscape of clinical effects. The purity of each substance with exact pharmacokinetic and toxicity profiles is largely unknown. Many of these substances can be grouped by the class of drug and includes synthetic cannabinoids, synthetic cathinones, phenethylamines, as well as piperazine derivatives. Resultant effects generally include psychoactive and sympathomimetic-like symptoms. Additionally, prescription medications, performance enhancing medications, and herbal supplements are also becoming more commonly abused. Most new drugs of abuse have no specific antidote and management largely involves symptom based goal directed supportive care with benzodiazepines as a useful adjunct. This paper will focus on the history, epidemiology, clinical effects, laboratory analysis, and management strategy for many of these emerging drugs of abuse. Copyright © 2014 Elsevier Inc.

  13. An endocannabinoid hypothesis of drug reward and drug addiction.

    2008-10-01

    Pharmacologic treatment of drug and alcohol dependency has largely been disappointing, and new therapeutic targets and hypotheses are needed. There is accumulating evidence indicating a central role for the previously unknown but ubiquitous endocannabinoid physiological control system (EPCS) in the regulation of the rewarding effects of abused substances. Thus an endocannabinoid hypothesis of drug reward is postulated. Endocannabinoids mediate retrograde signaling in neuronal tissues and are involved in the regulation of synaptic transmission to suppress neurotransmitter release by the presynaptic cannabinoid receptors (CB-Rs). This powerful modulatory action on synaptic transmission has significant functional implications and interactions with the effects of abused substances. Our data, along with those from other investigators, provide strong new evidence for a role for EPCS modulation in the effects of drugs of abuse, and specifically for involvement of cannabinoid receptors in the neural basis of addiction. Cannabinoids and endocannabinoids appear to be involved in adding to the rewarding effects of addictive substances, including, nicotine, opiates, alcohol, cocaine, and BDZs. The results suggest that the EPCS may be an important natural regulatory mechanism for drug reward and a target for the treatment of addictive disorders.

    Glutamate is the principal excitatory neurotransmitter in the central nervous system and its actions are related to the behavioral effects of psychostimulant drugs. In the last two decades, basic neuroscience research and preclinical studies with animal models are suggesting a critical role for glutamate transmission in drug reward, reinforcement, and relapse. Although most of the interest has been centered in post-synaptic glutamate receptors, the presynaptic synthesis of glutamate through brain glutaminases may also contribute to imbalances in glutamate homeostasis, a key feature of the glutamatergic hypothesis of addiction. Glutaminases are the main glutamate-producing enzymes in brain and dysregulation of their function have been associated with neurodegenerative diseases and neurological disorders; however, the possible implication of these enzymes in drug addiction remains largely unknown. This mini-review focuses on brain glutaminase isozymes and their alterations by in vivo exposure to drugs of abuse, which are discussed in the context of the glutamate homeostasis theory of addiction. Recent findings from mouse models have shown that drugs induce changes in the expression profiles of key glutamatergic transmission genes, although the molecular mechanisms that regulate drug-induced neuronal sensitization and behavioral plasticity are not clear.

    Full Text Available Claudia L Reardon, Shane Creado Department of Psychiatry, University of Wisconsin School of Medicine and Public Health, Madison, WI, USA Abstract: Drug abuse occurs in all sports and at most levels of competition. Athletic life may lead to drug abuse for a number of reasons, including for performance enhancement, to self-treat otherwise untreated mental illness, and to deal with stressors, such as pressure to perform, injuries, physical pain, and retirement from sport. This review examines the history of doping in athletes, the effects of different classes of substances used for doping, side effects of doping, the role of anti-doping organizations, and treatment of affected athletes. Doping goes back to ancient times, prior to the development of organized sports. Performance-enhancing drugs have continued to evolve, with “advances” in doping strategies driven by improved drug testing detection methods and advances in scientific research that can lead to the discovery and use of substances that may later be banned. Many sports organizations have come to ban the use of performance-enhancing drugs and have very strict consequences for people caught using them. There is variable evidence for the performance-enhancing effects and side effects of the various substances that are used for doping. Drug abuse in athletes should be addressed with preventive measures, education, motivational interviewing, and, when indicated, pharmacologic interventions.

The relations these discursive positions establish with the discourses of the master, the hysteric, the university and the capitalist are discussed. By analyzing material from clinical listening at a public outpatient drug and alcohol rehab center, it was seen that addiction can be described in different discourses. This article shows that the shift of focus from the symptom to the discursive position of the subject is an indicator for the clinical treatment of addiction.

    Drug abuse has resulted in a huge burden on public health and the economy in China. Since the reemergence of drug abuse in China in the 1980s, the number of drug addicts has increased dramatically, especially the proportion of users of synthetic drugs, such as amphetamine-type stimulant (ATS). Further, the proportion of opiate addicts has decreased among the new initiates. This review describes the new pattern of drug abuse and the resultant intervention strategy in China. The demographics regarding drug abuse in China point to a trend of younger users, and indicate that Internet and telephone are facilitating drug trafficking. Furthermore, polydrug use is common. Many heroin addicts have used ATS and other synthetic drugs, and some synthetic drug abusers have used opiate drugs too. HIV infection and psychosis comorbidity are primarily associated with drug abuse in China. Although opiate drug use and its associated harm have been controlled effectively in some areas, the synthetic drugs and new designer drugs have complicated the drug abuse scene. A national system of management and intervention for synthetic drugs and associated diseases urgently needs to be established in China.

    Drug addiction is a chronic brain disorder leading to complex adaptive changes within the brain reward circuits that involve several neurotransmitters. One of the neurochemical systems that plays a pivotal role in different aspects of addiction is the endogenous opioid system (EOS). Opioid receptors and endogenous opioid peptides are largely distributed in the mesolimbic system and modulate dopaminergic activity within these reward circuits. Chronic exposure to the different prototypical drugs of abuse, including opioids, alcohol, nicotine, psychostimulants and cannabinoids has been reported to produce significant alterations within the EOS, which seem to play an important role in the development of the addictive process. In this review, we will describe the adaptive changes produced by different drugs of abuse on the EOS, and the current knowledge about the contribution of each component of this neurobiological system to their addictive properties.

    Full Text Available Introduction and Aim. Further gains in the prevention of drug abuse disorders require in-depth and holistic understanding of the risk factors of addiction from different perspectives. Lay persons and experts have different concepts of risk which could complement each other. The purpose of this study was to elaborate drug abuse risk factors through the story of individuals who had become drug dependent. Design and Methods. In this qualitative research, 33 individuals attending treatment centres for drug abuse were interviewed about the story of their addiction in Kerman, Iran. Interview questions were around the story of the participants. Results. All participants were male and in the age range of 18–40 years. Narrative analysis identified five themes as the main risk factors: family factors, peer pressure, the effect of gateway drugs (especially waterpipe, individual characteristics, and the community factors. More emphasis was placed upon the role of family factors, peer influence, and gateway effect. Discussion and Conclusion. This study elicited information from drug dependent subjects regarding the risk factors of drug abuse. According to drug dependent individuals’ views, more attention should be devoted to family and peer influences by policy makers, in developing culture-based preventive strategies.

  2. Addictive drugs and brain stimulation reward.

    Science.gov (United States)

    Wise, R A

    1996-01-01

    Direct electrical or chemical stimulation of specific brain regions can establish response habits similar to those established by natural rewards such as food or sexual contact. Cocaine, mu and delta opiates, nicotine, phencyclidine, and cannabis each have actions that summate with rewarding electrical stimulation of the medial forebrain bundle (MFB). The reward-potentiating effects of amphetamine and opiates are associated with central sites of action where these drugs also have their direct rewarding effects, suggesting common mechanisms for drug reward per se and for drug potentiation of brain stimulation reward. The central sites at which these and perhaps other drugs of abuse potentiate brain stimulation reward and are rewarding in their own right are consistent with the hypothesis that the laboratory reward of brain stimulation and the pharmacological rewards of addictive drugs are habit forming because they act in the brain circuits that subserve more natural and biologically significant rewards.

    The Alcohol and Drug Abuse Research Unit (ADARU) was established at the South African Medical Research Council (MRC) at the beginning of 2001, although its origins lie in the activities of the Centre for Epidemiological Research in Southern Africa and other MRC entities. Initial challenges included attracting external funding, recruiting new staff, developing the skills of junior staff, publishing in international journals and building national and international collaborative networks. ADARU currently comprises a core staff of 33 members who work on 22 projects spanning substance use epidemiology and associated consequences, intervention studies with at-risk populations and services research. A large component of this portfolio focuses on the link between alcohol and other drug use and human immunodeficiency virus (HIV) risk behaviour, with funding from the US Centers for Disease Control and Prevention. Junior staff members are encouraged to develop independent research interests and pursue PhD studies. Research outputs, such as the 20 papers that were published in 2010 and the 35 conference presentations from that year, form an important part of the unit's research translation activities. We engage actively with policy processes at the local, provincial, national and international levels, and have given particular attention to alcohol policy in recent years. The paper includes an analysis of major challenges currently facing the unit and how we are attempting to address them. It ends with some thoughts on what the unit intends doing to enhance the quality of its research, the capacity of its staff and its international standing. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

    To determine the patterns of substance abuse of students attending the Lugo School of Nursing. Observational, descriptive and cross-sectional study in the classroom carried out by survey research in April 2015. 61.5% of students participated (185), 83.2% of whom were females. The first addictive substance consumed by participants was tobacco (at 15 years old). In the last month cigarettes were consumed by 36.2% of students, while alcohol was consumed by 89.9% (58.4% of the total got drunk). 2.2% were consuming tranquilizers/hypnotics in the same time period. The most widely used illegal drug was cannabis (17.8%) and then cocaine (2.2%). There is a significant correlation between illegal drug consumption and being male, smoking cigarettes or drinking alcohol, living alone or with friends (not family), have poor academic performance and public drinking (botellón). There were no association between illegal drugs and sports or reading. Polydrug use was also studied: a 16.2% declared to have consumed alcohol and cannabis simultaneously, and a 4.9% alcohol and cocaine. Consumption patterns are similar compared to the general population in that age group, with some of them being higher. Therefore, it is necessary to take measures in order to prevent substance abuse at the university level. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

    The development of animal models of drug reward and addiction is an essential factor for progress in understanding the biological basis of this disorder and for the identification of new therapeutic targets. Depending on the component of reward to be studied, one type of animal model or another may be used. There are models of reinforcement based on the primary hedonic effect produced by the consumption of the addictive substance, such as the self-administration (SA) and intracranial self-stimulation (ICSS) paradigms, and there are models based on the component of reward related to associative learning and cognitive ability to make predictions about obtaining reward in the future, such as the conditioned place preference (CPP) paradigm. In recent years these models have incorporated methodological modifications to study extinction, reinstatement and reconsolidation processes, or to model specific aspects of addictive behavior such as motivation to consume drugs, compulsive consumption or drug seeking under punishment situations. There are also models that link different reinforcement components or model voluntary motivation to consume (two-bottle choice, or drinking in the dark tests). In short, innovations in these models allow progress in scientific knowledge regarding the different aspects that lead individuals to consume a drug and develop compulsive consumption, providing a target for future treatments of addiction.

    Full Text Available Introduction: Child abuse includes abuse of the body, mental and sexual abuse or misbehavior against children that leads to damage to the child's heath and comfort. Therefore, the present study was done in order to determine the prevalence of child abuse in opiate addicts referring to addiction withdrawal centers. Methods: The cross sectional study included 300 participations (150 addicts and 150 non-addicts The addicted group comprised of opiate addicts referring to addiction withdrawal centers of Yazd. The non addicted group was selected randomly from healthy people. Data collection was performed via a standard questionnaire. Data assessment was done via statistical analysis (K S Results: Collected data in the addicted group showed the following results about 56 percent were child tormentors, 1- 45.3% males, 10.7% females, 2-18.7% uneducated, 3-46% with divorce history in their family and 4-38% child body abuse. The most prevalent type of the body abuse was slapping (24%, mostly because of bad training (26%. Collected data in the no addicted group showed the following results 42% were child tormentors (26% male and 15.3% female 23.4% with family divorce history, 30.4% were child body abuse and the most prevalent type of body abuse was slapping (22.79%, mostly because of bad training (33.3% Conclusion: A direct relationship was observed between child abuse and persons addicted to opiates. Factors playing an important role include illiteracy, divorce history in the family and history of child abuse in childhood period. Therefore, compilation of rules supporting children, establishment of support and parent education centers can be effective to reduce child persecution.

  13. Addictive drugs and their relationship with infectious diseases.

    The use of drugs of abuse, both recreationally and medicinally, may be related to serious public health concerns. There is a relationship between addictive drugs of abuse such as alcohol and nicotine in cigarette smoke, as well as illegal drugs such as opiates, cocaine and marijuana, and increased susceptibility to infections. The nature and mechanisms of immunomodulation induced by such drugs of abuse are described in this review. The effects of opiates and marijuana, using animal models as well as in vitro studies with immune cells from experimental animals and humans, have shown that immunomodulation induced by these drugs is mainly receptor-mediated, either directly by interaction with specific receptors on immune cells or indirectly by reaction with similar receptors on cells of the nervous system. Similar studies also show that cocaine and nicotine have marked immunomodulatory effects, which are mainly receptor-mediated. Both cocaine, an illegal drug, and nicotine, a widely used legal addictive component of cigarettes, are markedly immunomodulatory and increase susceptibility to infection. The nature and mechanism of immunomodulation induced by alcohol, the most widely used addictive substance of abuse, are similar but immunomodulatory effects, although not receptor-mediated. The many research studies on the effects of these drugs on immunity and increased susceptibility to infectious diseases, including AIDS, are providing a better understanding of the complex interactions between immunity, infections and substance abuse.

    There is overwhelming evidence that addiction is a disease of the brain (Leshner, 1997). Yet public perception that addiction is a reflection of moral weakness or a lack of willpower persists. The insidious consequence of this perception is that we lose sight of the fact that there are enormous medical consequences of addiction including the fact that a large fraction of the total deaths from cancer and heart disease are caused by smoking addiction. Ironically the medical school that educates physicians in addiction medicine and the cancer hospital that has a smoking cessation clinic are vanishingly rare and efforts at harm reduction are frequently met with a public indignation. Meanwhile the number of people addicted to substances is enormous and increasing particularly the addictions to cigarettes and alcohol. It is particularly tragic that addiction usually begins in adolescence and becomes a chronic relapsing problem and there are basically no completely effective treatments. Clearly we need to understand how drugs of abuse affect the brain and we need to be creative in using this information to develop effective treatments. Imaging technologies have played a major role in the conceptualization of addiction as a disease of the brain (Fowler et al., 1998a; Fowler et al., 1999a). New knowledge has been driven by advances in radiotracer design and chemistry and positron emission tomography (PET) instrumentation and the integration of these scientific tools with the tools of biochemistry, pharmacology and medicine. This topic cuts across the medical specialties of neurology, psychiatry, cancer and heart disease because of the high medical, social and economic toll that drugs of abuse, including and especially the legal drugs, cigarettes and alcohol, take on society. In this chapter we will begin by highlighting the important role that chemistry has played in making it possible to quantitatively image the movement of drugs as well as their effects on the human brain

    Full Text Available Narcotics is a highly addictive drug that acts as a stimulant or depresant for the central nervous system. The prevalence of various diseases found to be higher in the group of drug users then those who not use drugs such as endocarditis, hepatitis and HIV. Further evidence that the drug effects the oral health which includes the effect of the hard tissues by increased incidence of caries and periodontitis and the effect of the soft tissues in the form of leukoplakia and oral mucosal fibrosis, reduced production, especially the parotid salivary glands in amphetamine and cannabis users. In addition to the drug is a predisposing of oral infections such as candidiasis and gingivitis. Reduced volume of saliva on abusers may result in reduced immune function of saliva in maintaining oral health. Consequently the drug abusers increased number of bacteria and fungi in the oral cavity, including anaerobic bacteria and Candida albicans, especially in cases of abuse of cannabis. Gingival plaque formation and the growing colonies of anaerobic bacteria may increase the occurrence of gingivitis in the drug abusers. Lack of awareness of drug abusers in oral hygiene causing the gingivitis develops into periodontitis followed by alveolar bone loss.

  16. Drugs as instruments: a new framework for non-addictive psychoactive drug use.

    2011-12-01

    Most people who are regular consumers of psychoactive drugs are not drug addicts, nor will they ever become addicts. In neurobiological theories, non-addictive drug consumption is acknowledged only as a "necessary" prerequisite for addiction, but not as a stable and widespread behavior in its own right. This target article proposes a new neurobiological framework theory for non-addictive psychoactive drug consumption, introducing the concept of "drug instrumentalization." Psychoactive drugs are consumed for their effects on mental states. Humans are able to learn that mental states can be changed on purpose by drugs, in order to facilitate other, non-drug-related behaviors. We discuss specific "instrumentalization goals" and outline neurobiological mechanisms of how major classes of psychoactive drugs change mental states and serve non-drug-related behaviors. We argue that drug instrumentalization behavior may provide a functional adaptation to modern environments based on a historical selection for learning mechanisms that allow the dynamic modification of consummatory behavior. It is assumed that in order to effectively instrumentalize psychoactive drugs, the establishment of and retrieval from a drug memory is required. Here, we propose a new classification of different drug memory subtypes and discuss how they interact during drug instrumentalization learning and retrieval. Understanding the everyday utility and the learning mechanisms of non-addictive psychotropic drug use may help to prevent abuse and the transition to drug addiction in the future.

    Epidemiological data demonstrate that while women report lower rates of drug use than men, the number of current drug users and abusers who are women continues to increase. In addition women progress through the phases of addiction differently than men; women transition from casual drug use to addiction faster, are more reactive to stimuli that trigger relapse, and have higher rates of relapse then men. Sex differences in physiological and psychological responses to drugs of abuse are well documented and it is well established that estrogen effects on dopamine (DA) systems are largely responsible for these sex differences. However, the downstream mechanisms that result from interactions between estrogen and the effects of drugs of abuse on the DA system are just beginning to be explored. Here we review the basic neurocircuitry which underlies reward and addiction; highlighting the neuroadaptive changes that occur in the mesolimbic dopamine reward and anti-reward/stress pathways. We propose that sex differences in addiction are due to sex differences in the neural systems which mediate positive and negative reinforcement and that these differences are modulated by ovarian hormones. This forms a neurobehavioral basis for the search for the molecular and cellular underpinnings that uniquely guide motivational behaviors and make women more vulnerable to developing and sustaining addiction than men.

    To compare the risk of comorbid sexual addiction in a sample of individuals with a diagnosis of substance dependence, stratifying the sample by drug of choice as well as by mono versus polysubstance addiction. All data were collected at Santa Casa de São Paulo, Brazil. The study sample comprised all alcohol or drug dependents admitted to the Addiction Treatment Unit between November 2013 and August 2014. A generalized linear model with a binomial distribution was performed to compare the odds of having a Sexual Addiction Screening Test (SAST) score greater than 6 points in the subgroups analyzed. A total of 133 participants were included in our analysis, all reporting cocaine/crack and/or alcohol as drug of choice. Polysubstance addicts had a significant higher risk of a positive screening for sexual addiction compared to monosubstance addicts, age-sex adjusted odds ratios of sexual addiction being respectively 2.72 (95CI 1.1-6.71) and 0.37 (95CI 0.15-0.91). The odds of a SAST score greater than 6 was not statistically different between the cocaine/crack and alcohol groups, respectively 0.38 (95CI 0.14-1.02) and 2.67 (95CI 0.98-7.25). We found a significant relation between stronger drug addiction and greater levels of sexual addiction in the cocaine/crack group (p=0.0012), but not in the alcohol group. Our study reinforces the importance of assessing sexual behavior of drug addicts in clinical practice, especially considering users of multiple substances or with severe dependence.

    2017-01-01

    Drug addiction is a complex disorder which can be influenced by both genetic and environmental factors. Research has shown that epigenetic modifications can translate environmental signals into changes in gene expression, suggesting that epigenetic changes may underlie the causes and possibly treatment of substance use disorders. This chapter will focus on epigenetic modifications to DNA, which include DNA methylation and several recently defined additional DNA epigenetic changes. We will discuss the functions of DNA modifications and methods for detecting them, followed by a description of the research investigating the function and consequences of drug-induced changes in DNA methylation patterns. Understanding these epigenetic changes may provide us translational tools for the diagnosis and treatment of addiction in the future.

    Drug abuse is associated with a variety of neurological complications. The use of certain recreational drugs shows a marked temporal association with the onset of both haemorrhagic and ischaemic strokes, the majority of which develop within minutes to 1 h after the administration of the index drug. Delayed onset of stroke has also been observed. Acute, severe elevation of blood pressure, cardiac dysrhythmias, cerebral vasospasm, vasculitis, embolization due to infective endocarditis or dilated cardiomyopathy, embolization due to foreign material injected with the diluents under non-sterile conditions and 'street drug' contaminants with cardiovascular effects have been suggested as possible underlying mechanisms. Rupture of aneurysms and arteriovenous malformations have been detected in up to half of the patients with haemorrhagic stroke due to cocaine abuse. The less common findings reported have included a mycotic cerebrovascular aneurysm in a patient with infective endocarditis and haemorrhagic stroke. In addition to stroke, cocaine seems to provoke vascular headache. Seizures precipitated by recreational drug abuse are usually caused by acute intoxication in contrast to the withdrawal seizures encountered in subjects with alcohol abuse. Movement disorders and cerebral atrophy correlating with the duration of abuse have been described. Snorting of organic solvents may cause encephalopathy. Cases of spongiform leukoencephalopathy in heroin addicts have also been reported. Peripheral neuropathy is occasionally precipitated by drug poisoning after intravenous administration. Impurities of the drug, risky administration techniques, and the use of mixtures of various drugs, frequently with simultaneous alcohol drinking, should be taken into account when assessing the background of the adverse event as well as the overall lifestyle of the addicted subjects.

  2. Addicted to palatable foods: comparing the neurobiology of Bulimia Nervosa to that of drug addiction.

    2014-05-01

    Bulimia nervosa (BN) is highly comorbid with substance abuse and shares common phenotypic and genetic predispositions with drug addiction. Although treatments for the two disorders are similar, controversy remains about whether BN should be classified as addiction. Here, we review the animal and human literature with the goal of assessing whether BN and drug addiction share a common neurobiology. Similar neurobiological features are present following administration of drugs and bingeing on palatable food, especially sugar. Specifically, both disorders involve increases in extracellular dopamine (DA), D1 binding, D3 messenger RNA (mRNA), and ΔFosB in the nucleus accumbens (NAc). Animal models of BN reveal increases in ventral tegmental area (VTA) DA and enzymes involved in DA synthesis that resemble changes observed after exposure to addictive drugs. Additionally, alterations in the expression of glutamate receptors and prefrontal cortex activity present in human BN or following sugar bingeing in animals are comparable to the effects of addictive drugs. The two disorders differ in regards to alterations in NAc D2 binding, VTA DAT mRNA expression, and the efficacy of drugs targeting glutamate to treat these disorders. Although additional empirical studies are necessary, the synthesis of the two bodies of research presented here suggests that BN shares many neurobiological features with drug addiction. While few Food and Drug Administration-approved options currently exist for the treatment of drug addiction, pharmacotherapies developed in the future, which target the glutamate, DA, and opioid systems, may be beneficial for the treatment of both BN and drug addiction.

    Full Text Available Background: Substance abuse has significant impact on nutritional status. Due to the increased malnutrition during drug use and withdrawal, this study aimed at assessing the anthropometric indices in individuals referring to drug treatment centers in Qom. Methods: In this descriptive-analytical study, 329 addicted individuals referring to addiction centers in Qom were randomly selected. A questionnaire was used with three parts including demographic characteristics, drug abuse history, and anthropometric indices including measurement of height, weight, waist circumference, arm circumference, and skinfold thickness in triceps and calf muscles. Results: The participants consisted of 328 men and only one woman, 29% of whom were in detoxification. The participants' mean age was 39.0 ± 7.1 years. The first and most-frequently used drug was opium. All anthropometric indices were associated with the consumption of opium substances and drug use was associated significantly with some parameters. With the exception of skinfold thickness in the calf, all the indices were affected by the type of consumed substances. The opium addicts had a higher body mass index compared with other drug users. Conclusions: Due to the importance of nutrition status in drug abusers' health and their lack of self-care, careful monitoring and evaluation of dietary intake, as well as nutrition status can play important roles in the rehabilitation of these individuals and help to prevent from reappearance of these habits.

    Full Text Available Background and Objectives: Narcotics addiction is a chronic and relapsing  psychological disorder, which is associated with severe motivational disorders and loss of behavioural control. Addiction and abuse of narcotic substances have various predisposing factors in the areas of attitude, environment, and society. On the other hand, previous researches have shown that addiction causes transformation in the perception of social issues and type of attitude toward this problem. This study aimed to investigate the relationship between abuse of narcotic substances and psychological obstinacy, quality of life, and self-concept in the addicts. Methods: This research was a correlational study. Statistical population included individuals covered by addiction withdrawal centers of Qom city, who were selected (250 subjects by convenience sampling. Data collection was performed using drug screening, self-concept, psychological obstinacy and quality of life questionnaires. To analyse the data, Pearson correlation coefficient and regression tests, were used. Results: There was a significant negative correlation at the 0.05 level, between narcotics abuse and psychological obstinacy (-0.531. On the other hand, there was a significant negative correlation at the 0.05 levels, between narcotics abuse and quality of life (0.285. Also, there was a significant negative correlation at the 0.05 levels, between narcotics abuse and self-concept (-0.475. Conclusion: The results of this study showed that there is significant correlation (in 0.05 levels between narcotics abuse and psychological obstinacy, life quality, and self-concept, and individuals with higher narcotic abuse have lower psychological obstinacy, quality of life, and self-concept.

    In this review, we highlight the role of neuroimaging techniques in studying the emotional and cognitive-behavioral components of the addiction syndrome by focusing on the neural substrates subserving them. The phenomenology of drug addiction can be characterized by a recurrent pattern of subjective experiences that includes drug intoxication, craving, bingeing, and withdrawal with the cycle culminating in a persistent preoccupation with obtaining, consuming, and recovering from the drug. In the past two decades, imaging studies of drug addiction have demonstrated deficits in brain circuits related to reward and impulsivity. The current review focuses on studies employing positron emission tomography (PET), functional magnetic resonance imaging (fMRI), and electroencephalography (EEG) to investigate these behaviors in drug-addicted human populations. We begin with a brief account of drug addiction followed by a technical account of each of these imaging modalities. We then discuss how these techniques have uniquely contributed to a deeper understanding of addictive behaviors.

    The majority of adult people in western societies regularly consume psychoactive drugs. While this consumption is integrated in everyday life activities and controlled in most consumers, it may escalate and result in drug addiction. Non-addicted drug use requires the systematic establishment of highly organized behaviors, such as drug-seeking and -taking. While a significant role for classical and instrumental learning processes is well established in drug use and abuse, declarative drug memo...

  17. Prescription opioid abuse, pain and addiction: clinical issues and implications.

    2011-05-01

    Prescription opioid misuse in the USA has increased over threefold since 1990 to epidemic proportions, with substantial increases in prescription opioid use also reported in other countries, such as Australia and New Zealand. The broad availability of prescription pain medications, coupled with public misconceptions about their safety and addictive potential, have contributed to the recent surge in non-medical use of prescription opioids and corresponding increases in treatment admissions for problems related to opioid misuse. Given competing pressures faced by physicians to both diagnose and treat pain syndromes and identify individuals at risk for addictive disorders, the use of opioids in the treatment of pain poses a significant clinical challenge. This paper reviews the interaction between pain and opioid addiction with a focus on clinical management issues, including risk factors for opioid dependence in patients with chronic pain and the use of assessment tools to identify and monitor at-risk individuals. Treatment options for opioid dependence and pain are reviewed, including the use of the partial µ agonist buprenorphine in the management of concurrent pain and opioid addiction. Physicians should strive to find a reasonable balance between minimising potential adverse effects of opioid medications without diminishing legitimate access to opioids for analgesia. The article discusses the need to identify methods for minimising risks and negative consequences associated with opioid analgesics and poses research directions, including the development of abuse-deterrent opioid formulations, genetic risk factors for opioid dependence and opioid-induced hyperalgesia as a potential target for medication therapy. © 2011 Australasian Professional Society on Alcohol and other Drugs.

  18. Using Metabolomics to Investigate Biomarkers of Drug Addiction.

    Drug addiction has been associated with an increased risk for cancer, psychological complications, heart, liver, and lung disease, as well as infection. While genes have been identified that can mark individuals at risk for substance abuse, the initiation step of addiction is attributed to persistent metabolic disruptions occurring following the first instance of narcotic drug use. Advances in analytical technologies can enable the detection of thousands of signals in body fluids and excreta that can be used to define biochemical profiles of addiction. Today, these approaches hold promise for determining how exposure to drugs, in the absence or presence of other environmentally relevant factors, can impact human metabolism. We posit that these can lead to candidate biomarkers of drug dependence, treatment, withdrawal, or relapse. Copyright © 2017. Published by Elsevier Ltd.

    1976-07-01

    Psychotropic drug treatment of persons on methadone maintenance is discussed. Patients with clear target symptoms, such as anxiety, depression, or psychosis responded just as non-opioid addicts would to the major psychotropic agents. The minor tranquilizers are felt to be of doubtful value, and subject to abuse. Sleep disturbances cannot be treated by the usual means, as the drugs needed again are abused. However, chlorpromazine shows some promise here. Methods of drug delivery and goals of treatment must be adapted to the realities of this patient-group's characteristics, particularly anti-social traits, poor motivation and unreliability. Psychotropic drugs are unlikely to be of aid in multiple drug abusers, personality and character disorders, and opioid withdrawal. Four case histories are presented.

However, there is limited information concerning clinical profiles of individuals seeking detoxification, and the opportunity to engage patients in detoxification for aftercare often is missed. This study examined clinical profiles of a geographically diverse sample of opioid-dependent adults in detoxification to discern the treatment needs of a growing number of women and whites with opioid addiction and to inform interventions aimed at improving use of aftercare or rehabilitation.Methods: The sample included 343 opioid-dependent patients enrolled in two national multisite studies of the National Drug Abuse Treatment Clinical Trials Network (CTN001-002. Patients were recruited from 12 addiction treatment programs across the nation. Gender and racial/ethnic differences in addiction severity, human immunodeficiency virus (HIV risk, and quality of life were examined.Results: Women and whites were more likely than men and African Americans to have greater psychiatric and family/social relationship problems and report poorer health-related quality of life and functioning.

    Drug addiction is often underestimated among the aged. Opiate drugs (mostly pain killers) are the most frequently implicated in drug addiction after benzodiazepines (BZD) in the aged. The subjects aged of 65 years or more are the most represented among the BZD users in France. Frequency of BZD use varies according to various studies from 39 to 55% in this age group. Leading a lonely life is associated with the use of psychotropic drugs among retired people (OR=1.7). Vulnerability at this age must take into account not only polypathology, but also the faster aging of a minority of the population under opiate drugs substitution treatment (OST), more subjects to drugs interaction. Drug addiction among elderly often reflects the drift of "lawful" doctor's instructions that leads to an increase in drugs use. The difficulty has to do with a lack of specificity of diagnosis of addiction at this age, but perhaps also with physicans'instructions in the aged. Some authors suggest that continued and prolonged use should be considered the main criterion for BZD addiction at this age, with or without increase in doses and failed attempt at cessation. Besides, the prescription of BZD increases after retirement and loneliness.

  3. Molecular Mechanism: ERK Signaling, Drug Addiction, and Behavioral Effects.

    Science.gov (United States)

    Sun, Wei-Lun; Quizon, Pamela M; Zhu, Jun

    2016-01-01

    Addiction to psychostimulants has been considered as a chronic psychiatric disorder characterized by craving and compulsive drug seeking and use. Over the past two decades, accumulating evidence has demonstrated that repeated drug exposure causes long-lasting neurochemical and cellular changes that result in enduring neuroadaptation in brain circuitry and underlie compulsive drug consumption and relapse. Through intercellular signaling cascades, drugs of abuse induce remodeling in the rewarding circuitry that contributes to the neuroplasticity of learning and memory associated with addiction. Here, we review the role of the extracellular signal-regulated kinase (ERK), a member of the mitogen-activated protein kinase, and its related intracellular signaling pathways in drug-induced neuroadaptive changes that are associated with drug-mediated psychomotor activity, rewarding properties and relapse of drug seeking behaviors. We also discuss the neurobiological and behavioral effects of pharmacological and genetic interferences with ERK-associated molecular cascades in response to abused substances. Understanding the dynamic modulation of ERK signaling in response to drugs may provide novel molecular targets for therapeutic strategies to drug addiction. Copyright © 2016.

    This qualitative study summarizes information that individuals shared online about use of OxyContin following the August 2010 introduction of the abuse deterrent formulation (ADF). The primary objective was to study online posts that endorsed continued use of OxyContin or a switch from OxyContin to another formulation of oxycodone or another substance altogether following the introduction of the ADF. A secondary objective was to determine whether posts revealed that the ADF led to cessation of OxyContin use. Data were collected with the Researched Abuse, Diversion, and Addiction-Related Surveillance System Web Monitoring Program, an online surveillance system that collects and organizes posts about prescription drugs from social media websites, blogs, and forums from 3Q2009 to 4Q2014 using a commercially available web platform. Posts were categorized by whether they conveyed a switch to drugs other than reformulated OxyContin or a continuation of reformulated OxyContin abuse. "Switch posts" primarily discussed switching to immediate-release opioids. "Continue abusing" posts identified tampering strategies for alternate routes of administration, oral use, and continued use although post authors were generally unhappy with the experience. No reference to OxyContin cessation as a function of the introduction of the ADF was found; however, discontinued use was discussed. Web Monitoring data are useful for capturing cross sections of Internet conversation reflecting reactions to new drug formulations. These data support the notion that users will gravitate to non-ADFs generally, and to immediate-release non-ADF opioid formulations, specifically, as long as these options remain on the market.

  10. Glutamatergic substrates of drug addiction and alcoholism1

    2008-01-01

    The past two decades have witnessed a dramatic accumulation of evidence indicating that the excitatory amino acid glutamate plays an important role in drug addiction and alcoholism. The purpose of this review is to summarize findings on glutamatergic substrates of addiction, surveying data from both human and animal studies. The effects of various drugs of abuse on glutamatergic neurotransmission are discussed, as are the effects of pharmacological or genetic manipulation of various components of glutamate transmission on drug reinforcement, conditioned reward, extinction, and relapse-like behavior. In addition, glutamatergic agents that are currently in use or are undergoing testing in clinical trials for the treatment of addiction are discussed, including acamprosate, N-acetylcysteine, modafinil, topiramate, lamotrigine, gabapentin and mematine. All drugs of abuse appear to modulate glutamatergic transmission, albeit by different mechanisms, and this modulation of glutamate transmission is believed to result in long-lasting neuroplastic changes in the brain that may contribute to the perseveration of drug-seeking behavior and drug-associated memories. In general, attenuation of glutamatergic transmission reduces drug reward, reinforcement, and relapse-like behavior. On the other hand, potentiation of glutamatergic transmission appears to facilitate the extinction of drug-seeking behavior. However, attempts at identifying genetic polymorphisms in components of glutamate transmission in humans have yielded only a limited number of candidate genes that may serve as risk factors for the development of addiction. Nonetheless, manipulation of glutamatergic neurotransmission appears to be a promising avenue of research in developing improved therapeutic agents for the treatment of drug addiction and alcoholism.

    Addiction is a chronic, relapsing disease of the brain that includes drug-induced compulsive seeking behavior and consumption of drugs. Dopamine (DA) is considered to be critical in drug addiction due to reward mechanisms in the midbrain. In this article, we review the major animal models in addictive drug experiments in vivo and in vitro. We discuss the relevance of the structure and pharmacological function of DA receptors. To improve the understanding of the role of DA receptors in reward pathways, specific brain regions, including the Ventral tegmental area, Nucleus accumbens, Prefrontal cortex, and Habenula, are highlighted. These factors contribute to the development of novel therapeutic targets that act at DA receptors. In addiction, the development of neuroimaging method will increase our understanding of the mechanisms underlying drug addiction.

  12. Pharmacotherapies for decreasing maladaptive choice in drug addiction: Targeting the behavior and the drug.

    Science.gov (United States)

    Perkins, Frank N; Freeman, Kevin B

    2018-01-01

    Drug addiction can be conceptualized as a disorder of maladaptive decision making in which drugs are chosen at the expense of pro-social, nondrug alternatives. The study of decision making in drug addiction has focused largely on the role of impulsivity as a facilitator of addiction, in particular the tendency for drug abusers to choose small, immediate gains over larger but delayed outcomes (i.e., delay discounting). A parallel line of work, also focused on decision making in drug addiction, has focused on identifying the determinants underlying the choice to take drugs over nondrug alternatives (i.e., drug vs. nondrug choice). Both tracks of research have been valuable tools in the development of pharmacotherapies for treating maladaptive decision making in drug addiction, and a number of common drugs have been studied in both designs. However, we have observed that there is little uniformity in the administration regimens of potential treatments between the designs, which hinders congruence in the development of single treatment strategies to reduce both impulsive behavior and drug choice. The current review provides an overview of the drugs that have been tested in both delay-discounting and drug-choice designs, and focuses on drugs that reduced the maladaptive choice in both designs. Suggestions to enhance congruence between the findings in future studies are provided. Finally, we propose the use of a hybridized, experimental approach that may enable researchers to test the effectiveness of therapeutics at decreasing impulsive and drug choice in a single design.

    The study involved 152 adolescents which had abused narcotic and toxic substances once, occasionally or regularly. Males aged 15 to 16 years displayed highest occurrence rate of the abuse. Drug addiction and toxicomania were established in 6% of subjects. Volatile stuff and tranquilizers were most frequent in use. Microsocial adversities were experienced by all the subjects. Besides, an "altered background" is characteristic of drug addicts and toxicomania patients. The fact of narcotic and toxic substances usage as euphorigenic agents deserves due attention of narcologists, pedagogues, sociologists. Biologically conditioned risk factors conducive to drug addiction and toxicomania should be investigated.

  16. Vaccines against drugs of abuse: a viable treatment option?

    Science.gov (United States)

    Kantak, Kathleen M

    2003-01-01

    Drug addiction is a chronically relapsing brain disorder. There is an urgent need for new treatment options for this disease because the relapse rate among drug abusers seeking treatment is quite high. During the past decade, many groups have explored the feasibility of using vaccines directed against drugs of abuse as a means of eliminating illicit drug use as well as drug overdose and neurotoxicity. Vaccines work by inducing drug-specific antibodies in the bloodstream that bind to the drug of abuse and prevent its entry into the brain. The majority of work in this area has been conducted with vaccines and antibodies directed against cocaine and nicotine. On the basis of preclinical work, vaccines for cocaine and nicotine are now in clinical trials because they can offer long-term protection with minimal treatment compliance. In addition, vaccines and antibodies for phencyclidine, methamphetamine and heroin abuse are currently under development. An underlying theme in this research is the need for high concentrations of circulating drug-specific antibodies to reduce drug-seeking and drug-taking behaviour when the drug is repeatedly available, especially in high doses. Although vaccines against drugs of abuse may become a viable treatment option, there are several drawbacks that need to be considered. These include: a lack of protection against a structurally dissimilar drug that produces the same effects as the drug of choice;a lack of an effect on drug craving that predisposes an addict to relapse; and tremendous individual variability in antibody formation. Forced or coerced vaccination is not likely to work from a scientific perspective, and also carries serious legal and ethical concerns. All things considered, vaccination against a drug of abuse is likely to work best with individuals who are highly motivated to quit using drugs altogether and as part of a comprehensive treatment programme. As such, the medical treatment of drug abuse will not be radically

    2017-01-01

    This chapter summarizes recent developments in preclinical and clinical research on Chinese herbal medicines and their neurochemical mechanism of action for the treatment of drug addiction. We searched Chinese and English scientific literature and selected several kinds of Chinese herbal medicines that have beneficial effects on drug addiction. Ginseng (Renshen) may be clinically useful for the prevention of opioid abuse and dependence. Rhizoma Corydalis (Yanhusuo) may be used to prevent relapse to chronic drug dependence. Alkaloids of Uncaria rhynchophylla (Gouteng) appear to have positive effects on methamphetamine and ketamine addiction. Both Salvia miltiorrhiza (Danshen) and Radix Pueraiae (Gegen) have beneficial inhibitory effects on alcohol intake. Sinomenine has been shown to have preventive and curative effects on opioid dependence. l-Stepholidine, an alkaloid extract of the Chinese herb Stephania intermedia (Rulan), attenuated the acquisition, maintenance, and reacquisition of morphine-induced conditioned place preference and antagonized the heroin-induced reinstatement of heroin seeking. Traditional Chinese herbal medicines may be used to complement current treatments for drug addiction, including withdrawal and relapse. As the molecular mechanisms of action of traditional Chinese herbal medicines are elucidated, further advances in their use for the treatment of drug addiction are promising. © 2017 Elsevier Inc.

All patients underwent bone scintigraphy with 17-20 mCi of /sup 99/sup(m)Tc labeling either pyrophosphate or methylene diphosphonate. Whole body and spot scans located the area of disease in most patients. This permitted biopsy of the affected area when the pathogen recurs. One of the two patients whose scintigrams were normal was on adequate treatment before the bone scintigram and the other was on oxacillin. Radiographs of the affected areas were normal, which indicates bone scintigraphy should be preferred to radiography in the early diagnosis of osseous infections.

    The mobile phone is a relatively new technological tool, versatile and accessible, and very attractive, especially for young people, but whose use involves a risk of abuse and addictive behavior. In recent years there has been increasing interest in this problem, especially in view of the fact that it involves an increasingly younger population. The aim of this paper is to review the current state of scientific knowledge about cell phone addiction/abuse. To this end, a search was carried out in international databases, using the descriptors "mobile phone", "cellular telephones", "addiction" and "abuse", and focusing on prevalence studies, diagnostic tests, associations with psychological variables and gender differences. There is a conceptual vagueness about the concepts of abuse and addiction in relation to mobile phones, and wide disparity in the adoption of diagnostic criteria; moreover, there are numerous instruments for the assessment of these concepts. As a result, the estimated prevalence ranges from 0-38%, depending on the scale used and the characteristics of the population studied. Surprisingly, self-attribution of cell phone addiction exceeds the prevalence estimated in the studies themselves. The personality trait most consistently associated with addiction is low self-esteem, though extraversion is associated with more intense use. Women with low self-esteem are the most vulnerable group, and the most commonly associated psychopathological symptom was depression. In short, while the evidence suggests a problem in relation to mobile phone use, the vagueness of the cell phone addiction concept and the poor quality of the studies make it difficult to generalize the results. It is necessary to define and unify criteria with a view to carrying out quality studies that permit appropriate comparisons.

    Tapentadol, a Schedule II opioid with a combination of µ-opioid activity and norepinephrine reuptake inhibition, is used for the management of moderate to severe acute and chronic pain. Its dual mechanism of action is thought to reduce opioid-related side effects that can complicate pain management. Since approval, tapentadol has been tracked across multiple outcomes suggesting abuse liability, and a pattern of relatively low, although not absent, abuse liability has been found. This retrospective cohort study further details the abuse liability of tapentadol as an active pharmaceutical ingredient (API) when immediate-release as well as extended-release formulations were on the market together (fourth quarter of 2011 to second quarter of 2016). Tapentadol (API) was compared with tramadol, hydrocodone, morphine, oxycodone, hydromorphone, and oxymorphone across Poison Center, Drug Diversion, and Treatment Center Programs Combined data streams from the Researched Abuse, Diversion and Addiction-Related Surveillance system. Findings suggest the public health burden related to tapentadol to date is low, but present. Event rates of abuse per population-level denominators were significantly lower than all other opioids examined. However, when adjusted for drug availability, event rates of abuse were lower than most Schedule II opioids studied, but were not the lowest. Disentangling these 2 sets of findings further by examining various opioid formulations, such as extended-release and the role of abuse-deterrent formulations, is warranted. This article presents the results from an examination of tapentadol API across the Researched Abuse, Diversion and Addiction-Related Surveillance System: a broad and carefully designed postmarketing mosaic. Data to date from Poison Center, Drug Diversion, and Treatment Centers combined suggest a low, but present public health burden related to tapentadol. Copyright © 2018. Published by Elsevier Inc.

  5. Imaging neurotransmitter release by drugs of abuse.

    2010-01-01

    Previous studies have shown that imaging with positron emission tomography (PET) and single photon emission computed tomography (SPECT) radiotracers that are specific for brain dopamine receptors can be used to indirectly image the change in the levels of neurotransmitters within the brain. Most of the studies in addiction have focused on dopamine, since the dopamine neurons that project to the striatum have been shown to play a critical role in mediating addictive behavior. These imaging studies have shown that increased extracellular dopamine produced by psychostimulants can be measured with PET and SPECT. However, there are some technical issues associated with imaging changes in dopamine, and these are reviewed in this chapter. Among these are the loss of sensitivity, the time course of dopamine pulse relative to PET and SPECT imaging, and the question of affinity state of the receptor. In addition, animal studies have shown that most drugs of abuse increase extracellular dopamine in the striatum, yet not all produce a change in neurotransmitter that can be measured. As a result, imaging with a psychostimulant has become the preferred method for imaging presynaptic dopamine transmission, and this method has been used in studies of addiction. The results of these studies suggest that cocaine and alcohol addiction are associated with a loss of dopamine transmission, and a number of studies show that this loss correlates with severity of disease.

    2015-02-01

    Drug addiction involves long-term behavioral abnormalities and gene expression changes throughout the mesolimbic dopamine system. Epigenetic mechanisms establish/maintain alterations in gene expression in the brain, providing the impetus for investigations characterizing how epigenetic processes mediate the effects of drugs of abuse. This review focuses on evidence that epigenetic events, specifically histone modifications, regulate gene expression changes throughout the reward circuitry. Drugs of abuse induce changes in histone modifications throughout the reward circuitry by altering histone-modifying enzymes, manipulation of which reveals a role for histone modification in addiction-related behaviors. There is a complex interplay between these enzymes, resulting in a histone signature of the addicted phenotype. Insights gained from these studies are key to identifying novel targets for diagnosis and therapy. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2015-01-01

    Full Text Available Alcohol and other drugs of abuse, including psychostimulants and opioids, can induce epigenetic changes: a contributing factor for drug addiction, tolerance and associated withdrawal symptoms. DNA methylation is the major epigenetic mechanism and it is one of more than 200 methylation reactions supported by methyl donor S-adenosylmethionine (SAM. The levels of SAM are controlled by cellular redox status via the folate and vitamin B12-dependent enzyme methionine synthase (MS, for example; under oxidative conditions MS is inhibited, diverting its substrate homocysteine (HCY to the transsulfuration pathway. Alcohol, dopamine and morphine, can alter intracellular levels of glutathione (GSH-based cellular redox status, subsequently affecting S-adenosylmethionine (SAM levels and DNA methylation status. In this discussion, we compile this and other existing evidence in a coherent manner to present a novel hypothesis implicating the involvement of redox-based epigenetic changes in drug addiction. Next, we also discuss how gene priming phenomenon can contribute to maintenance of redox and methylation status homeostasis under various stimuli including drugs of abuse. Lastly, based on our hypothesis and some preliminary evidence, we discuss a mechanistic explanation for use of metabolic interventions / redox-replenishers as symptomatic treatment of alcohol addiction and associated withdrawal symptoms. Hence, the current review article strengthens the hypothesis that neuronal metabolism has a critical bidirectional coupling with epigenetic changes in drug addiction and we support this claim via exemplifying the link between redox-based metabolic changes and resultant epigenetic consequences under the effect of drugs of abuse.

    Drug addiction is a serious worldwide problem with strong genetic and environmental influences. Different technologies have revealed a variety of genes and pathways underlying addiction; however, each individual technology can be biased and incomplete. We integrated 2,343 items of evidence from peer-reviewed publications between 1976 and 2006 linking genes and chromosome regions to addiction by single-gene strategies, microrray, proteomics, or genetic studies. We identified 1,500 human addiction-related genes and developed KARG (http://karg.cbi.pku.edu.cn), the first molecular database for addiction-related genes with extensive annotations and a friendly Web interface. We then performed a meta-analysis of 396 genes that were supported by two or more independent items of evidence to identify 18 molecular pathways that were statistically significantly enriched, covering both upstream signaling events and downstream effects. Five molecular pathways significantly enriched for all four different types of addictive drugs were identified as common pathways which may underlie shared rewarding and addictive actions, including two new ones, GnRH signaling pathway and gap junction. We connected the common pathways into a hypothetical common molecular network for addiction. We observed that fast and slow positive feedback loops were interlinked through CAMKII, which may provide clues to explain some of the irreversible features of addiction. PMID:18179280

    Periostitis and osteomyelitis can occur in drug addicts not only by hematogeneous dissemination of the infecting organisms, but as a result of introduction of bacteria by direct injection into periosteum or injection through infected skin and subcutaneous tissues. A spectrum of examples of osteomyelitis of the bones of the forearm in drug addicts is presented to illustrate this phenomenon. Neglect of these infections and the trauma of continued injections can lead to extensive tissue and bone loss. (orig.)

    Full Text Available Introduction: Drug abuse is a global phenomenon, affecting almost every country, but its extent and characteristics differ from region to region. India too is caught in this vicious circle of drug abuse, and the numbers of drug addicts are increasing day by day. The bane of drug abuse in Punjab has acquired the proportions of a pestilence that has shaken the entire society in the state. It is observed that in Punjab “drug abuse” is a raging epidemic, especially among the young. Methodology: The present cross-sectional study was conducted on 400 adolescents and young adults (11–35 years from 15 villages of Jalandhar District. Systematic sampling (probability proportionate to size was used for the selection of study subjects. A preformed, semi-structured questionnaire was used to collect information on type and frequency of drugs abused and other sociodemographic variables. The statistical evaluation of the data was performed using SPSS software, version 21.0. Results: The prevalence of substance abuse among study group was 65.5% and most common substance abused was alcohol (41.8%, followed by tobacco (21.3%. A high prevalence of heroin abusers was noted among study subjects (20.8%. The prevalence of nonalcohol and nontobacco substance abuse was 34.8%. A significant association of drug abuse was observed with male gender, illiteracy, and age above 30 years. Conclusions: The problem of drug abuse in youth of Punjab is a matter of serious concern as every third person is hooked to drugs other than alcohol and tobacco. The other striking observations were the high prevalence of heroin and intravenous drug abuse.

    Drug-addiction may trigger early onset of age-related disease, due to drug-induced multi-system toxicity and perilous lifestyle, which remains mostly undetected and untreated. We present the literature on pathophysiological processes that may hasten aging and its relevance to addiction, including: oxidative stress and cellular aging, inflammation in periphery and brain, decline in brain volume and function, and early onset of cardiac, cerebrovascular, kidney, and liver disease. Timely detection of accelerated aging in addiction is crucial for the prevention of premature morbidity and mortality.

    Carroll, Marilyn E; Smethells, John R

    2015-01-01

    The purpose of this review is to discuss recent findings related to sex differences in behavioral dyscontrol that lead to drug addiction, and clinical implications for humans are discussed. This review includes research conducted in animals and humans that reveals fundamental aspects of behavioral dyscontrol. The importance of sex differences in aspects of behavioral dyscontrol, such as impulsivity and compulsivity, is discussed as major determinants of drug addiction. Behavioral dyscontrol during adolescence is also an important consideration, as this is the time of onset for drug addiction. These vulnerability factors additively increase drug-abuse vulnerability, and they are integral aspects of addiction that covary and interact with sex differences. Sex differences in treatments for drug addiction are also reviewed in terms of their ability to modify the behavioral dyscontrol that underlies addictive behavior. Customized treatments to reduce behavioral dyscontrol are discussed, such as (1) using natural consequences such as non-drug rewards (e.g., exercise) to maintain abstinence, or using punishment as a consequence for drug use, (2) targeting factors that underlie behavioral dyscontrol, such as impulsivity or anxiety, by repurposing medications to relieve these underlying conditions, and (3) combining two or more novel behavioral or pharmacological treatments to produce additive reductions in drug seeking. Recent published work has indicated that factors contributing to behavioral dyscontrol are an important target for advancing our knowledge on the etiology of drug abuse, intervening with the drug addiction process and developing novel treatments.

  1. Addiction and autonomy: can addicted people consent to the prescription of their drug of addiction?

    Science.gov (United States)

    Foddy, Bennett; Savulescu, Julian

    2006-02-01

    It is often claimed that the autonomy of heroin addicts is compromised when they are choosing between taking their drug of addiction and abstaining. This is the basis of claims that they are incompetent to give consent to be prescribed heroin. We reject these claims on a number of empirical and theoretical grounds. First we argue that addicts are likely to be sober, and thus capable of rational thought, when approaching researchers to participate in research. We reject behavioural evidence purported to establish that addicts lack autonomy. We present an argument that extrinsic forces must be irresistible in order to make a choice non-autonomous. We argue that heroin does not present such an irresistible force. We make a case that drug-oriented desires are strong regular appetitive desires, which do not compromise consent. Finally we argue that an addict's apparent desire to engage in a harmful act cannot be construed as evidence of irrational or compulsive thought. On these arguments, a sober heroin addict must be considered competent, autonomous and capable of giving consent. More generally, any argument against legalisation of drugs or supporting infringement of the liberty of those desiring to take drugs of addiction must be based on considerations of harm and paternalism, and not on false claims that addicts lack freedom of the will.

    Dopamine (DA) is involved in drug reinforcement, but its role in drug addiction remains unclear. Positron emission tomography (PET) is the first technology used for the direct measurement of components of the dopaminergic system in the living human brain. In this article, we reviewed the major findings of PET imaging studies on the involvement of DA in drug addiction, especially in heroin addiction. Furthermore, we summarized PET radiotracers that have been used to study the role of DA in drug addiction. To investigate presynaptic function in drug addiction, PET tracers have been developed to measure DA synthesis and transport. For the investigation of postsynaptic function, several radioligands targeting dopamine one (D1) receptor and dopamine two (D2) receptor are extensively used in PET imaging studies. Moreover, we also summarized the PET imaging findings of heroin addiction studies, including heroin-induced DA increases and the reinforcement, role of DA in the long-term effects of heroin abuse, DA and vulnerability to heroin abuse and the treatment implications. PET imaging studies have corroborated the role of DA in drug addiction and increase our understanding the mechanism of drug addiction. Copyright © 2012 Wiley Periodicals, Inc.

    Drug abuse has a long, but also different history in Germany and China. The Opium War largely influenced the history of China in 19th century; however, China was once recognized as a drug-free nation for 3 decades from the 1950s to the 1980s. Drug abuse has spread quickly since re-emerging as a national problem in China in the late 1980s. The number of registered drug abusers increased from 70 000 in 1990 to more than 1 million by the end of 2005. In past decades, illicit drug trafficking and production have swept most provinces in China, and drug abuse has caused many problems for both abusers and the community. One major drug-related problem is the spread of HIV, which has caused major social and economic damage in China. Germany, the largest developed European country, also faces the drug and addiction problem. Germany has about 150 000 heroin addicts, for whom HIV/AIDS has become a serious threat since the mid 1980s. To control the drug problem, the German Government adopted the pAction Plan on Drugs and Addictionq in 2003; the China Central Government approved a similar regulation in the antidrug campaign in 2005. Germany has experience in reducing drug-related harm. The methadone maintenance treatment (MMT) program has run for more than 20 years and the public has become more tolerant of addicts. In 2003, China began the MMT program for controlling the spread of HIV/AIDS. It is necessary for China to learn from developed countries to acquire success in its antidrug campaign. In this review, we will go over the differences and similarities in drug abuse between Germany and China. The differences are related to history, population and economics, drug policy context, drug laws, HIV/hepatitis C virus infection, the MMT program and so on. These 2 nations have drug abuse problems with different histories and currently use different approaches to handle illicit drug marketing and use. The legal penalties for illicit drug offences reflect the social differences of

  16. The development and maintenance of drug addiction.

    Science.gov (United States)

    Wise, Roy A; Koob, George F

    2014-01-01

    What is the defining property of addiction? We dust off a several-decades-long debate about the relative importance of two forms of reinforcement—positive reinforcement, subjectively linked to drug-induced euphoria, and negative reinforcement, subjectively linked to the alleviation of pain—both of which figure importantly in addiction theory; each of these forms has dominated addiction theory in its time. We agree that addiction begins with the formation of habits through positive reinforcement and that drug-opposite physiological responses often establish the conditions for negative reinforcement to come into play at a time when tolerance, in the form of increasing reward thresholds, appears to develop into positive reinforcement. Wise’s work has tended to focus on positive-reinforcement mechanisms that are important for establishing drug-seeking habits and reinstating them quickly after periods of abstinence, whereas Koob’s work has tended to focus on the negative-reinforcement mechanisms that become most obvious in the late stages of sustained addiction. While we tend to agree with each other about the early and late stages of addiction, we hold different views as to (i) the point between early and late at which the diagnosis of ‘addiction’ should be invoked, (ii) the relative importance of positive and negative reinforcement leading up to this transition, and (iii) the degree to which the specifics of negative reinforcement can be generalized across the range of addictive agents.

    Substance abuse is a common problem among HIV-infected individuals. Importantly, addictions as well as moderate use of alcohol, smoking, or other illicit drugs have been identified as major reasons for non-adherence to antiretroviral therapy (ART) among HIV patients. The literature also suggests a decrease in the response to ART among HIV patients who use these substances, leading to failure to achieve optimal virological response and increased disease progression. This review discusses the challenges with adherence to ART as well as observed drug interactions and known toxicities with major drugs of abuse, such as alcohol, smoking, methamphetamine, cocaine, marijuana, and opioids. The lack of adherence and drug interactions potentially lead to decreased efficacy of ART drugs and increased ART, and drugs of abuse-mediated toxicity. As CYP is the common pathway in metabolizing both ART and drugs of abuse, we discuss the possible involvement of CYP pathways in such drug interactions. We acknowledge that further studies focusing on common metabolic pathways involving CYP and advance research in this area would help to potentially develop novel/alternate interventions and drug dose/regimen adjustments to improve medication outcomes in HIV patients who consume drugs of abuse.

  18. Sex differences in behavioral dyscontrol: Role in drug addiction and novel treatments

    Full Text Available The purpose of this review is to discuss recent findings related to sex differences in behavioral dyscontrol that lead to drug addiction, and clinical implications for humans are discussed. This review includes research conducted in animals and humans that reveals fundamental aspects of behavioral dyscontrol. The importance of sex differences in aspects of behavioral dyscontrol, such as impulsivity and compulsivity, are discussed as major determinants of drug addiction. Behavioral dyscontrol during adolescence is also an important consideration, as this is the time of onset for drug addiction. These vulnerability factors additively increase drug abuse vulnerability, and they are integral aspects of addiction that covary and interact with sex differences. Sex differences in treatments for drug addiction are also reviewed in terms of their ability to modify the behavioral dyscontrol that underlies addictive behavior. Customized treatments to reduce behavioral dyscontrol are discussed, such as: 1 using natural consequences such as nondrug rewards (e.g., exercise to maintain abstinence, or using punishment as a consequence for drug use, 2 targeting factors that underlie behavioral dyscontrol, such as impulsivity or anxiety, by repurposing medications to relieve these underlying conditions, and 3 combining two or more novel behavioral or pharmacological treatments to produce additive reductions in drug seeking. Recent published work has indicated that factors contributing to behavioral dyscontrol are an important target for advancing our knowledge on the etiology of drug abuse, intervening with the drug addiction process and developing novel treatments.

  1. Episodic memories and their relevance for psychoactive drug use and addiction.

    2013-01-01

    The majority of adult people in western societies regularly consume psychoactive drugs. While this consumption is integrated in everyday life activities and controlled in most consumers, it may escalate and result in drug addiction. Non-addicted drug use requires the systematic establishment of highly organized behaviors, such as drug-seeking and -taking. While a significant role for classical and instrumental learning processes is well established in drug use and abuse, declarative drug memories have largely been neglected in research. Episodic memories are an important part of the declarative memories. Here a role of episodic drug memories in the establishment of non-addicted drug use and its transition to addiction is suggested. In relation to psychoactive drug consumption, episodic drug memories are formed when a person prepares for consumption, when the drug is consumed and, most important, when acute effects, withdrawal, craving, and relapse are experienced. Episodic drug memories are one-trial memories with emotional components that can be much stronger than "normal" episodic memories. Their establishment coincides with drug-induced neuronal activation and plasticity. These memories may be highly extinction resistant and influence psychoactive drug consumption, in particular during initial establishment and at the transition to "drug instrumentalization." In that, understanding how addictive drugs interact with episodic memory circuits in the brain may provide crucial information for how drug use and addiction are established.

    The aim of this survey was to evaluate the distribution of pathological gamblers treated in an alcohol or drug addiction treatment program run by the Italian National Health Service providing assistance to alcohol and drug abusers in Venice (North east Italy) from September 1 to December 31, 2001. Each drug- or alcohol-dependent patient retained for treatment for at least one month was administrated an anonymous precoded questionnaire to collect personal and socio-demographic features. The South Oaks Gambling Screen (SOGS) was used to measure pathological gambling and the Symptom Checklist-90-Revised (SCL-90-R) to measure psychological distress levels and psychiatric symptoms. Among the 113 enrolled subjects we found a greater prevalence of pathological gamblers among drug users than among alcoholics and drug abusers were younger than alcoholics; moreover, there was a prevalence of single status, low schooling, and a low-medium income despite full-time occupation. Only pathological gamblers revealed a significant positive correlation with a family history of gambling and reached positive scores (>1.5) for some likely psychiatric symptoms. Abuse disorders and pathological gambling are frequently associated with multidependence personality traits. Preventing substance abuse may reduce the pathological gambling rates and better results can be obtained with educational campaigns beginning earlier in life.

  5. Overlaps in the nosology of substance abuse and overeating: the translational implications of "food addiction".

    The obesity epidemic has led to the postulation that highly palatable foods may be "addictive" for some individuals. This idea is supported by the fact that there are overlaps in brain circuitry that underlie addictive behavior as well as overeating. In this paper, we discuss the utility of the concept of "food addiction" as it may relate to treating certain disordered eating behaviors. Using criteria set forth in the DSM-IV for substance-use disorders, we review data that have emerged from animal models suggesting that overeating, in the form of binge eating, fits some of the criteria for substance abuse. Further, we discuss preclinical data revealing that the addiction-like behavioral changes observed in response to overeating are concomitant with neurochemical changes that are similar to those observed in response to drugs of abuse. With this background and evidence in mind, we conclude this article with a discussion as to how "food addiction" research may translate into clinical strategies and pharmaceutical treatments useful in curtailing overeating.

    Violent deaths are of considerable importance among young adults, since they account for half the deaths in this age group (average age 26.4 years). Suicide and accidents (both categories including drug overdoses) are the most frequent categories of deaths from non-natural causes, while in the USA deaths by homicide are also of considerable importance. Current repressive policies have not brought the problem of drug addiction under control. Each year deaths by overdose among drug abusers occur. Nevertheless, 40% of deaths among drug addicts are from other causes, principally accidents and suicides. In the near future, AIDS may well account for the majority of deaths among drug addicts, thus adding to the mortality from overdose, both accidental and suicidal. Has the time come to reconsider the problem of drug abuse and to find radical solutions which would previously have been unthinkable?

    Adaptation of the nervous system to different chemical and physiologic conditions is important for the homeostasis of brain processes and for learning and remembering appropriate responses to challenges. Although processes such as tolerance and dependence to various drugs of abuse have been known for a long time, it was recently discovered that even a single pharmacologically relevant dose of various drugs of abuse induces neuroplasticity in selected neuronal populations, such as the dopamine neurons of the ventral tegmental area, which persist long after the drug has been excreted. Prolonged (self-) administration of drugs induces gene expression, neurochemical, neurophysiological, and structural changes in many brain cell populations. These region-specific changes correlate with addiction, drug intake, and conditioned drugs effects, such as cue- or stress-induced reinstatement of drug seeking. In rodents, adolescent drug exposure often causes significantly more behavioral changes later in adulthood than a corresponding exposure in adults. Clinically the most impairing and devastating effects on the brain are produced by alcohol during fetal development. In adult recreational drug users or in medicated patients, it has been difficult to find persistent functional or behavioral changes, suggesting that heavy exposure to drugs of abuse is needed for neurotoxicity and for persistent emotional and cognitive alterations. This review describes recent advances in this important area of research, which harbors the aim of translating this knowledge to better treatments for addictions and related neuropsychiatric illnesses.

  8. Psychophysiological prediction of choice: relevance to insight and drug addiction

    An important goal of addiction research and treatment is to predict behavioural responses to drug-related stimuli. This goal is especially important for patients with impaired insight, which can interfere with therapeutic interventions and potentially invalidate self-report questionnaires. This research tested (i) whether event-related potentials, specifically the late positive potential, predict choice to view cocaine images in cocaine addiction; and (ii) whether such behaviour prediction differs by insight (operationalized in this study as self-awareness of image choice). Fifty-nine cocaine abusers and 32 healthy controls provided data for the following laboratory components that were completed in a fixed-sequence (to establish prediction): (i) event-related potential recordings while passively viewing pleasant, unpleasant, neutral and cocaine images, during which early (400–1000 ms) and late (1000–2000 ms) window late positive potentials were collected; (ii) self-reported arousal ratings for each picture; and (iii) two previously validated tasks: one to assess choice for viewing these same images, and the other to group cocaine abusers by insight. Results showed that pleasant-related late positive potentials and arousal ratings predicted pleasant choice (the choice to view pleasant pictures) in all subjects, validating the method. In the cocaine abusers, the predictive ability of the late positive potentials and arousal ratings depended on insight. Cocaine-related late positive potentials better predicted cocaine image choice in cocaine abusers with impaired insight. Another emotion-relevant event-related potential component (the early posterior negativity) did not show these results, indicating specificity of the late positive potential. In contrast, arousal ratings better predicted respective cocaine image choice (and actual cocaine use severity) in cocaine abusers with intact insight. Taken together, the late positive potential could serve as a biomarker

    A growing body of literature shows that a link exists between substance abuse and stress and that the crosstalk of sex hormones with the neuroendocrine system might differently prime vulnerability to drug addiction in male and female subjects. Thus, understanding the neurobiological mechanisms of addiction and the identification of sex-driven determinants in vulnerability to drug abuse may help to better devise and/or implement strategic (pharmacological, behavioural, social) interventions to prevent or face the issue of addiction. Differences between sexes can be found at all stages of life (in both the animal model and human studies) and may account for genetic, epigenetic and environmental/hormonal factors that in turn affect the functionality of the whole organism leading also to a sex-driven differential vulnerability or resilience to non-communicable pathologies. These include the onset and precipitation of stress-related psychiatric disorders as well as "substance-related and addictive disorders" (as defined in the DSM-V). This paper reviews the scientific literature highlighting significant differences in male and female subjects in stress and neuroendocrine function and the implications for sex-dependent differential vulnerability to drug addiction.

    2011-05-01

    Positron emission tomography (PET) neuroimaging in nonhuman primates has led to significant advances in our current understanding of the neurobiology and treatment of stimulant addiction in humans. PET neuroimaging has defined the in vivo biodistribution and pharmacokinetics of abused drugs and related these findings to the time course of behavioral effects associated with their addictive properties. With novel radiotracers and enhanced resolution, PET neuroimaging techniques have also characterized in vivo drug interactions with specific protein targets in the brain, including neurotransmitter receptors and transporters. In vivo determinations of cerebral blood flow and metabolism have localized brain circuits implicated in the effects of abused drugs and drug-associated stimuli. Moreover, determinations of the predisposing factors to chronic drug use and long-term neurobiological consequences of chronic drug use, such as potential neurotoxicity, have led to novel insights regarding the pathology and treatment of drug addiction. However, similar approaches clearly need to be extended to drug classes other than stimulants. Although dopaminergic systems have been extensively studied, other neurotransmitter systems known to play a critical role in the pharmacological effects of abused drugs have been largely ignored in nonhuman primate PET neuroimaging. Finally, the study of brain activation with PET neuroimaging has been replaced in humans mostly by functional magnetic resonance imaging (fMRI). There has been some success in implementing pharmacological fMRI in awake nonhuman primates. Nevertheless, the unique versatility of PET imaging will continue to complement the systems-level strengths of fMRI, especially in the context of nonhuman primate drug abuse research.

  13. 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.

    A survey was carried out to gather information on knowledge, attitudes and perception of parents and their children in relation to drug abuse matters. Significantly more teenagers knew more of the cause of drug addiction, as well as places for treatment and rehabilitation. Both teenagers and parents were also aware of reasons why drug addicts find it difficult to change their habits, mainly lacking motivation to stop taking drugs and that drug addicts do not have the power to control themselves. Teenagers were significantly more aware of effects of negative parental attitudes contributing to drug abuse, apart from school factors. Personal experiences before abusing drugs such as knowledge of pleasurable effects of drugs and where to obtain them has also a role to play in leading to drug abuse. There was also agreement that unfulfilled needs such as 'not being respected recognised for ones capabilities' and 'not being loved or treated fairly by parents', were causes of drug abuse. Significantly more teenagers knew of the ways of abusing drugs, mainly by injection, smoking and sniffing, and also sources of information via the mass media, social clubs, rehabilitation centres and schools. However, both the parents and teenagers were relatively ignorant of the long term effects of abusing drugs.

  15. Forensic and family psychiatry in abuse dwarfism: Munchausen's syndrome by proxy, atonement, and addiction to abuse.

    Money, J; Annecillo, C; Hutchison, J W

    1985-01-01

    The syndrome of abuse dwarfism is characterized by gross impairment of statural and intellectual growth and social maturation while the abused child remains in the domicile of abuse. The parents collude as child abusers, and are medical impostors regarding the symptoms of abuse. The syndrome as a whole is appropriately named Munchausen's syndrome by proxy. Though the mother typically initiates abuse, she cannot give a rational explanation for doing so. In her own history there is a sin that is expiated or atoned for symbolically by the sacrifice of the child--explainable in terms of the theory of opponent-process learning. In the two cases presented, the sin was the mother's own birth out of wedlock, in one case as a sequel to incest. The child's addiction to abuse is a challenge to the program of rehabilitation. With respect to parents at risk, the data of this paper are relevant to the prevention of a predisposition toward, or the actual implementation of child abuse, though a program of prevention needs still to be formulated. The sexological relevance of this paper is that the data demonstrate that the effects of sexual abuse may be transmitted to the next generation and manifested as child abuse which is not necessarily sexual in content.

    Glutamate plays a pivotal role in drug addiction, and the N-methyl-D-aspartate (NMDA) glutamate receptor subtype serves as a molecular target for several drugs of abuse. In this review, we will provide an overview of NMDA receptor structure and function, followed by a review of the mechanism of action, clinical efficacy, and side effect profile of NMDA receptor ligands that are currently in use or being explored for the treatment of drug addiction. These ligands include the NMDA receptor modulators memantine and acamprosate, as well as the partial NMDA agonist D-cycloserine. Data collected to date suggest that direct NMDA receptor modulators have relatively limited efficacy in the treatment of drug addiction, and that partial agonism of NMDA receptors may have some efficacy with regards to extinction learning during cue exposure therapy. However, the lack of consistency in results to date clearly indicates that additional studies are needed, as are studies examining novel ligands with indirect mechanisms for altering NMDA receptor function.

    2016-01-04

    The term "drug of abuse" is highly contextual. What constitutes a drug of abuse for one population of patients does not for another. It is therefore important to examine the needs of the patient population to properly assess the status of drugs of abuse. The focus of this article is on the bidirectional relationship between patients and drug abuse. In this paper we will introduce the dopaminergic systems of the brain in Parkinson's and the influence of antiparkinsonian drugs upon them before discussing this synergy of condition and medication as fertile ground for drug abuse. We will then examine the relationship between drugs of abuse and Parkinson's, both beneficial and deleterious. In summary we will draw the different strands together and speculate on the future merit of current drugs of abuse as treatments for Parkinson's disease. Copyright © 2015 Elsevier Inc.

    Relationships were explored among the frequencies of use of various drugs by a sample of drug-abusing clients of the Addiction Research Foundation (ARF) in Toronto and by drug abusers volunteering to participate in research at the Addiction Research Center (ARC) in Baltimore. The two groups of drug-abusing individuals differed in a number of characteristics. Those from ARF were admitted primarily for diagnosis and possible treatment for alcohol and non-opioid drug problems, whereas those from the ARC were admitted for participation in research on other drugs of abuse, primarily involving opioids. Patterns of use of certain drugs tended to covary in both groups. Of particular interest was the finding that severity of alcoholism was directly related to various measures of tobacco and caffeinated beverage use. In contrast, there was little correlation between the frequency of use among other drugs of abuse (e.g., heroin, cannabis, glue) and the use of tobacco and caffeine. These findings suggest that dependence on nicotine, caffeine, and alcohol may be governed by the same factors and possibly should be considered jointly in the treatment of alcoholic persons. Frequency of use of other drugs examined may be controlled by other factors than those which determine level of use of tobacco and caffeine.

    Difficulties of biological, psychological, social and legal nature may be seen involved in the treatment of drug-addict persons. In this study, the major models used in the treatment are analysed, so as so one may arrived at a new model which will better integrate the various factors involved. The major models may be brought down to three: the medical psychiatric model which emphasizes the biological dependency on drugs and which equates drug addiction and "mental illness"; the behavioristic model which utilizes directive conditioning and desensitizing techniques, as well as educational and suggestional means, in order to determine new kinds of behavior; the relational model which takes origin from psychoanalysis and the systemic approach and sponsors a non-directive treatment of the drug-addict through the exploration and work on his personal and social unconscious conflicts, drive and desires, as well as his self-destructive tendencies. To assure the drug-addict a way to assume responsibility for his own behavior and to be free by respecting other people's rights, it is necessary to elaborate an integrative model of treatment which will consider also the anthropological specificity of the problems, referring also to the Brazilian society.

    This article provides an overview on prescription drug abuse and highlights a number of related legislative bills introduced during the 112th Congress in response to this growing epidemic. Prescription drug abuse has emerged as the nation's fastest growing drug problem. Although prescription drugs have been used effectively and appropriately for decades, deaths from prescription pain medicine in particular have reached epidemic proportions. Bills related to prescription drug abuse introduced during the 112th Congress focus on strengthening provider and consumer education, tracking and monitoring prescription drug abuse, improving data collection on drug overdose fatalities, combating fraud and abuse in Medicare and Medicaid programs, reclassifying drugs to make them more difficult to prescribe and obtain, and enforcing stricter penalties for individuals who operate scam pain clinics and sell pain pills illegitimately. This article underscores the importance of a multifaceted approach to combating prescription drug abuse and concludes with implications for nursing. Copyright © 2013. Published by Mosby, Inc.

    Phasic increases in brain dopamine are required for cue-directed reward seeking. While compelling within the framework of appetitive behavior, the view that illicit drugs hijack reward circuits by hyper-activating these dopamine transients is inconsistent with established psychostimulant pharmacology. However, recent work reclassifying amphetamine (AMPH), cocaine, and other addictive dopamine-transporter inhibitors (DAT-Is) supports transient hyper-activation as a unifying hypothesis of abuse...

  7. S-Glutathionylation and Redox Protein Signaling in Drug Addiction.

    Science.gov (United States)

    Womersley, Jacqueline S; Uys, Joachim D

    2016-01-01

    Drug addiction is a chronic relapsing disorder that comes at a high cost to individuals and society. Therefore understanding the mechanisms by which drugs exert their effects is of prime importance. Drugs of abuse increase the production of reactive oxygen and nitrogen species resulting in oxidative stress. This change in redox homeostasis increases the conjugation of glutathione to protein cysteine residues; a process called S-glutathionylation. Although traditionally regarded as a protective mechanism against irreversible protein oxidation, accumulated evidence suggests a more nuanced role for S-glutathionylation, namely as a mediator in redox-sensitive protein signaling. The reversible modification of protein thiols leading to alteration in function under different physiologic/pathologic conditions provides a mechanism whereby change in redox status can be translated into a functional response. As such, S-glutathionylation represents an understudied means of post-translational protein modification that may be important in the mechanisms underlying drug addiction. This review will discuss the evidence for S-glutathionylation as a redox-sensing mechanism and how this may be involved in the response to drug-induced oxidative stress. The function of S-glutathionylated proteins involved in neurotransmission, dendritic spine structure, and drug-induced behavioral outputs will be reviewed with specific reference to alcohol, cocaine, and heroin.

    Drug addiction is a multileveled behavior controlled by interactions among many diverse neuronal groups involving several neurotransmitter systems. The involvement of brainstem-sourced, cholinergic neurotransmission in the development of addiction and in the persistent physiological processes that drive this maladaptive behavior has not been widely investigated. The major cholinergic input to neurons in the midbrain which are instrumental in assessment of reward and assignment of salience to stimuli, including drugs of abuse, sources from acetylcholine- (ACh-) containing pontine neurons of the laterodorsal tegmentum (LDT). Excitatory LDT input, likely cholinergic, is critical in allowing behaviorally relevant neuronal firing patterns within midbrain reward circuitry. Via this control, the LDT is positioned to be importantly involved in development of compulsive, addictive patterns of behavior. The goal of this review is to present the anatomical, physiological, and behavioral evidence suggesting a role of the LDT in the neurobiology underlying addiction to drugs of abuse. Although focus is directed on the evidence supporting a vital participation of the cholinergic neurons of the LDT, data indicating a contribution of noncholinergic LDT neurons to processes underlying addiction are also reviewed. While sparse, available information of actions of drugs of abuse on LDT cells and the output of these neurons as well as their influence on addiction-related behavior are also presented. Taken together, data from studies presented in this review strongly support the position that the LDT is a major player in the neurobiology of drug addiction. Accordingly, the LDT may serve as a future treatment target for efficacious pharmaceutical combat of drug addiction.

    2018-04-01

    The study of sex as a biological variable is a necessary emphasis across a wide array of endpoints, including basic neuroscience, medicine, mental health, physiology and behavior. The present review summarizes work from clinical and preclinical populations on sex differences in drug use and abuse, ranging from initiation to escalation/dysregulation and from drug cessation/abstinence to relapse. These differences are analyzed in the context of the addiction cycle conceptualization of Koob and his colleagues and address patterns of drug use (binge/intoxication), motivation underlying its use (withdrawal/negative affect) and likelihood and causes of craving and relapse of drug taking (preoccupation/anticipation). Following this overview, an assessment of the basis for the reported sex differences is discussed in the context of the affective (rewarding and aversive) properties of drugs of abuse and how such properties and their balance vary with sex and contribute to drug intake. Finally, the interaction of sex with several experiential (drug history) and subject (age) factors and how these interactions affect reward and aversion are discussed to highlight the importance of understanding such interactions in predicting drug use and abuse. We note that sex as a biological variable remains one of critical evaluation and that such investigations of sex differences in drug use and abuse continue and be expanded to assess all facets of their mediation, including these affective properties, how their balance may be impacted by the multiple conditions under which drugs are taken and how this overall balance affects drug use and addiction vulnerability.

    The nucleus accumbens is a major input structure of the basal ganglia and integrates information from cortical and limbic structures to mediate goal-directed behaviors. Chronic exposure to several classes of drugs of abuse disrupts plasticity in this region, allowing drug-associated cues to engender a pathologic motivation for drug seeking. A number of alterations in glutamatergic transmission occur within the nucleus accumbens after withdrawal from chronic drug exposure. These drug-induced neuroadaptations serve as the molecular basis for relapse vulnerability. In this review, we focus on the role that glutamate signal transduction in the nucleus accumbens plays in addiction-related behaviors. First, we explore the nucleus accumbens, including the cell types and neuronal populations present as well as afferent and efferent connections. Next we discuss rodent models of addiction and assess the viability of these models for testing candidate pharmacotherapies for the prevention of relapse. Then we provide a review of the literature describing how synaptic plasticity in the accumbens is altered after exposure to drugs of abuse and withdrawal and also how pharmacological manipulation of glutamate systems in the accumbens can inhibit drug seeking in the laboratory setting. Finally, we examine results from clinical trials in which pharmacotherapies designed to manipulate glutamate systems have been effective in treating relapse in human patients. Further elucidation of how drugs of abuse alter glutamatergic plasticity within the accumbens will be necessary for the development of new therapeutics for the treatment of addiction across all classes of addictive substances.

  12. Neural and psychological mechanisms underlying compulsive drug seeking habits and drug memories--indications for novel treatments of addiction.

    2014-07-01

    This review discusses the evidence for the hypothesis that the development of drug addiction can be understood in terms of interactions between Pavlovian and instrumental learning and memory mechanisms in the brain that underlie the seeking and taking of drugs. It is argued that these behaviours initially are goal-directed, but increasingly become elicited as stimulus-response habits by drug-associated conditioned stimuli that are established by Pavlovian conditioning. It is further argued that compulsive drug use emerges as the result of a loss of prefrontal cortical inhibitory control over drug seeking habits. Data are reviewed that indicate these transitions from use to abuse to addiction depend upon shifts from ventral to dorsal striatal control over behaviour, mediated in part by serial connectivity between the striatum and midbrain dopamine systems. Only some individuals lose control over their drug use, and the importance of behavioural impulsivity as a vulnerability trait predicting stimulant abuse and addiction in animals and humans, together with consideration of an emerging neuroendophenotype for addiction are discussed. Finally, the potential for developing treatments for addiction is considered in light of the neuropsychological advances that are reviewed, including the possibility of targeting drug memory reconsolidation and extinction to reduce Pavlovian influences on drug seeking as a means of promoting abstinence and preventing relapse. © 2014 The Author.

    We review the evaluation and treatment of patients with drug addictions complicated by other acute or chronic diseases from the perspective of the hospital setting. The spectrum of drug addiction's complications is broad and in many instances it is predetermined by the abuse substance and its administration route. Some complications of intravenous drug addiction have dramatically decreased in the last few years as a result of a better knowledge of hygienic customs and after the implementation of some health interventions such as the provision of sterile injectable devices. Two highly prevalent infections --HIV/AIDS and hepatitis C-- remain from the period in which most HIV infections owed to the intravenous use of heroin. Of note, these two infections largely account for the survival and quality of life of those who quit their addiction. On the other hand, it is still common the hospitalization of patients with both alcohol dependence and intercurrent diseases in whom their drug addiction may pass unnoticed. Other common situations include the treatment of acute patients with cocaine addiction and psychiatric comorbidity, patients under methadone therapy and, in general, all those cases in which, in emergency, ordinary hospital wards and specialized units, a wide differential diagnosis is raised when there is a coexistence of signs and symptoms common to an addiction, infection and/or intoxication. An integral vision of drug addiction and its complications, as well as the clinical evaluation of all health problems, is fundamental for the prognosis and treatment of these patients.

  14. [Are there any sex/gender differences in drug use and drug addiction?].

    Science.gov (United States)

    Mendrek, Adrianna

    Drug use and drug addiction have been traditionally considered to be a male problem, however the gender gap has been decreasing over the past few decades. Thus, while the prevalence of alcohol, cannabis and nicotine dependence is still overall greater among men than among women, sex/gender differences in the abuse of stimulants and opiates seem to have disappeared. Moreover, women appear to be more prone to develop drug dependence, suffer more severe physical and psychological consequences of drug abuse, and have more difficulties quitting the habit. Numerous psychological, socio-cultural and biological factors have been implicated in these changing statistics. For example, while a large proportion of men initiate drug use to induce feelings of elation, energy or focus, women frequently start taking drugs to alleviate pre-existing mental health problems, including high levels of stress, feelings of alienation, depression, anxiety, or post-traumatic stress disorder. This maladaptive self-medication strategy often results in a faster transition to a habitual drug use and eventually a more severe dependence. In addition, the socio-cultural norms (particularly in the Western society) have changed dramatically over the past few decades. Thus, while there is still a more severe stigma and prejudice against women who use drugs (especially if they are pregnant of have children), overall there is much greater acceptance of women's drug use than it was several decades ago. Moreover, women have much greater access to various drugs of abuse than they used to have. Finally, over the past couple of decades new research started emerging pointing to some neurobiological factors that could also contribute to sex differences in drug addiction. Thus, there is now evidence that dopamine system, which for decades has been strongly implicated in drug reinforcement, is sexually dimorphic. The number of dopaminergic neurons, the density of the dopaminergic terminals, as well as

    Much has been presented and debated on the topic of drug abuse and its multidimensional nature, including the role of society and its customs and laws, economical factors, and the magnitude and nature of the burden. Given the complex nature of the receptors and pathways implicated in regulation of the cognitive and behavioral processes associated with addiction, a large number of molecular targets have been interrogated during recent years to discover starting points for development of small-molecule interventions. This review describes recent developments in the field of early drug discovery for drug abuse interventions with an emphasis on the advances published during the 2012 - 2014 period. Technologically, the processes/platforms utilized in drug abuse drug discovery are nearly identical to those used in the other disease areas. A key complicating factor in drug abuse research is the enormous biological complexity surrounding the brain processes involved and the associated difficulty in finding 'good' targets and achieving exquisite selectivity of treatment agents. While tremendous progress has been made during recent years to use the power of high-throughput technologies to discover proof-of-principle molecules for many new targets, next-generation models will be especially important in this field. Examples include: seeking advantageous drug-drug combinations, the use of automated whole-animal behavioral screening systems, advancing our understanding of the role of epigenetics in drug addiction and the employment of organoid-level 3D test platforms (also referred to as tissue-chip or organs-on-chip).

    Psychiatric disease is overlooked in drug users. Patients with both drug abuse and a psychiatric disease - dual diagnosis - suffer decreased compliance to treatment and decreased life expectancy compared with single-diagnosis patients. Identifying the patients among either drug addicts or mentally ill patients is difficult. All drug addicts autopsied at the Department of Forensic Medicine, University of Copenhagen, Denmark, in the years 1992, 2002 and 2012 were included. The group was divided into two subpopulations of possible dual diagnosis patients either according to police reports stating mental illness or to psychotropics found in the toxicology screening after autopsy. We found a rise in possible mental illness in both subpopulations in the study period. Drug addicts with psychotropics in the blood at the time of death increased from 3.1% in 1992 to 48.1% in 2012, and this group was significantly younger at the time of death than those without psychotropics in the blood. Suspected dual diagnosis patients have increased in number. They die earlier than their drug addict counterparts. Methadone remains the leading cause of death in all subpopulations. Possible causes are misuse of treatment and/or illegally bought methadone, wrongly assigned cause of death due to unknown tolerance and/or polydrug toxicity in combination with psychotropic medicine. none. not relevant.

    Since the 1970s, media frenzies about drug addiction have focused mainly on illicit drugs taken by rebellious or marginalised addicts, relegating iatrogenic drug abuse, and policies and problems linked to psychotropic pharmaceuticals available by prescription or over-the-counter to the shadows. In this article I go beyond the division between illicit drugs and medicines still configuring both public representations and historiography: using archival materials from the 1960s-1990s in France, I highlight some blind spots in drug history. Firstly I demonstrate the role of pharmaceutical abuse in the career of addicts, and then examine regulation policies, which are the dark side, however complementary, of drug policies and prohibition. Finally, I analyse the role of physicians and pharmacists in this control, and discuss the various professional debates relating to the legal supply of psychoactive drugs. In all these issues, the frame of the Cold War context will also be highlighted.

  3. MicroRNAs and drug addiction

    Full Text Available Drug addiction is considered a disorder of neuroplasticity in brain reward and cognition systems resulting from aberrant activation of gene expression programs in response to prolonged drug consumption. Noncoding RNAs are key regulators of almost all aspects of cellular physiology. MicroRNAs (miRNAs are small (~21–23 nucleotides noncoding RNA transcripts that regulate gene expression at the post-transcriptional level. Recently, microRNAs were shown to play key roles in the drug-induced remodeling of brain reward systems that likely drives the emergence of addiction. Here, we review evidence suggesting that one particular miRNA, miR-212, plays a particularly prominent role in vulnerability to cocaine addiction. We review evidence showing that miR-212 expression is increased in the dorsal striatum of rats that show compulsive-like cocaine-taking behaviors. Increases in miR-212 expression appear to protect against cocaine addiction, as virus-mediated striatal miR-212 over-expression decreases cocaine consumption in rats. Conversely, disruption of striatal miR-212 signaling using an antisense oligonucleotide increases cocaine intake. We also review data that identify two mechanisms by which miR-212 may regulate cocaine intake. First, miR-212 has been shown to amplify striatal CREB signaling through a mechanism involving activation of Raf1 kinase. Second, miR-212 was also shown to regulate cocaine intake by repressing striatal expression of methyl CpG binding protein 2 (MeCP2, consequently decreasing protein levels of brain-derived neurotrophic factor (BDNF. The concerted actions of miR-212 on striatal CREB and MeCP2/BDNF activity greatly attenuate the motivational effects of cocaine. These findings highlight the unique role for miRNAs in simultaneously controlling multiple signaling cascades implicated in addiction.

    Although imaging studies in and of themselves have significant contributions to the study of human behavior, imaging in drug abuse has a much broader agenda. Drugs of abuse bind to molecules in specific parts of the brain in order to produce their effects. Positron emission tomography (PET) provides a unique opportunity to track this process, capturing the kinetics with which an abused compound is transported to its site of action. The specific examples discussed here were chosen to illustrate how PET can be used to map the regional distribution and kinetics of compounds that may or may not have abuse liability. We also discussed some morphological and functional changes associated with drug abuse and different stages of recovery following abstinence. PET measurements of functional changes in the brain have also led to the development of several treatment strategies, one of which is discussed in detail here. Information such as this becomes more than a matter of academic interest. Such knowledge can provide the bases for anticipating which compounds may be abused and which may not. It can also be used to identify biological markers or changes in brain function that are associated with progression from drug use to drug abuse and also to stage the recovery process. This new knowledge can guide legislative initiatives on the optimal duration of mandatory treatment stays, promoting long-lasting abstinence and greatly reducing the societal burden of drug abuse. Imaging can also give some insights into potential pharmacotherapeutic targets to manage the reinforcing effects of addictive compounds, as well as into protective strategies to minimize their toxic consequences.

  8. Individual differences and vulnerability to drug addiction: a focus on the endocannabinoid system.

    Sagheddu, Claudia; Melis, Miriam

    2015-01-01

    Vulnerability to drug addiction depends upon the interactions between the biological makeup of the individual, the environment, and age. These interactions are complex and difficult to tease apart. Since dopamine is involved in the rewarding effects of drugs of abuse, it is postulated that innate differences in mesocorticolimbic pathway can influence the response to drug exposure. In particular, higher and lower expression of dopamine D2 receptors in the ventral striatum (i.e. a marker of dopamine function) has been considered a putative protective and a risk factor, respectively, that can influence one's susceptibility to continued drug abuse as well as the transition to addiction. This phenomenon, which is phylogenetically preserved, appears to be a compensatory change to increased impulse activity of midbrain dopamine neurons. Hence, dopamine neuronal excitability plays a fundamental role in the diverse stages of the drug addiction cycle. In this review, a framework for the evidence that modulation of dopamine neuronal activity plays in the context of vulnerability to drug addiction will be presented. Furthermore, since endogenous cannabinoids serve as retrograde messengers to shape afferent neuronal activity in a short- and long-lasting fashion, their role in individual differences and vulnerability to drug addiction will be discussed.

    In recent decades, the decline in human fertility has become increasingly more worrying: while therapeutic interventions might help, they are vexing for the couple and often burdened with high failure rates and costs. Prevention is the most successful approach to fertility disorders in males and females alike. We performed a literature review on three of the most common unhealthy habits - tobacco, alcohol and drug addiction - and their reported effects on male fertility. Tobacco smoking is remarkably common in most first-world countries; despite a progressive decline in the US, recent reports suggest a prevalence of more than 30% in subjects of reproductive age - a disturbing perspective, given the well-known ill-effects on reproductive and sexual function as well as general health. Alcohol consumption is often considered socially acceptable, but its negative effects on gonadal function have been consistently reported in the last 30 years. Several studies have reported a variety of negative effects on male fertility following drug abuse - a worrying phenomenon, as illicit drug consumption is on the rise, most notably in younger subjects. While evidence in these regards is still far from solid, mostly as a result of several confounding factors, it is safe to assume that cessation of tobacco smoking, alcohol consumption and recreational drug addiction might represent the best course of action for any couple trying to achieve pregnancy.

    Global treatment of drug addiction costs society billions of dollars annually, but current psychopharmacological therapies have not been successful at desired rates. The increasing number of individuals suffering from substance abuse has turned attention to what makes some people more vulnerable to drug addiction than others. One personality trait that stands out as a contributing factor is novelty seeking. Novelty seeking, affected by both genetic and environmental factors, is defined as the tendency to desire novel stimuli and environments. It can be measured in humans through questionnaires and in rodents using behavioral tasks. On the behavioral level, both human and rodent studies demonstrate that high novelty seeking can predict the initiation of drug use and a transition to compulsive drug use and create a propensity to relapse. These predictions are valid for several drugs of abuse, such as alcohol, nicotine, cocaine, amphetamine, and opiates. On the molecular level, both novelty seeking and addiction are modulated by the central reward system in the brain. Dopamine is the primary neurotransmitter involved in the overlapping neural substrates of both parameters. In sum, the novelty-seeking trait can be valuable for predicting individual vulnerability to drug addiction and for generating successful treatment for patients with substance abuse disorders.

    Full Text Available The striatum plays a key role in mediating the acute and chronic effects of addictive drugs, with drugs of abuse causing long-lasting molecular and cellular alterations in both dorsal striatum and nucleus accumbens (ventral striatum. Despite the wealth of research on the biological actions of abused drugs in striatum, until recently, the distinct roles of the striatum’s two major subtypes of medium spiny neuron (MSN in drug addiction remained elusive. Recent advances in cell-type specific technologies, including fluorescent reporter mice, transgenic or knockout mice, and viral-mediated gene transfer, have advanced the field toward a more comprehensive understanding of the two MSN subtypes in the long-term actions of drugs of abuse. Here we review progress in defining the distinct molecular and functional contributions of the two MSN subtypes in mediating addiction.

    Full Text Available Drug abuse has become a global issue of concern. It affects not only individual users, but also their families and communities. Data were retrieved from the database of the Taiwan Surveillance System of Drug Abuse and Addiction Treatment (SSDAAT from 2002 to 2011, and 147,660 cases reported by medical institutions in Taiwan were reviewed. This study showed that the top five reported abused drugs by medical institutions during the last decade were heroin, methamphetamine, benzodiazepines, ketamine, and zolpidem. Heroin and methamphetamine continued to be the first two abused drugs reported by medical institutions. Heroin abuse was significant, but has shown a downward trend. However, emerging abused drugs, such as ketamine and zolpidem, presented upward trends. 3,4-Methylenedioxy-N-methylamphetamine (MDMA abuse seems to have re-emerged and has increased gradually since 2010. Injection without needle sharing has become the most common route of administration of abused drugs since 2002. The majority of causes for these reported drug abuses were drug dependence, followed by peer influence and stress relief. Hepatitis C was the most commonly reported infectious disease, followed by hepatitis B and AIDS in the drug abusers reported by medical institutions. It should be noted that access to drugs via the Internet increased year by year, and this is clearly an area needing constant monitoring.

    To describe 8 cases of toxic keratopathy due to abuse of topical anesthetic drugs. Clinical findings from patients with toxic keratopathy were investigated retrospectively. Two patients had toxic keratopathy bilaterally. Five of 8 patients had an ocular history of a corneal foreign body, 1 had basal membrane dystrophy, 1 had ultraviolet radiation, and 1 had chemical burn. All patients had undergone psychiatric consultation. Four patients had anxiety disorder and 1 had bipolar disease. Clinical signs were improved in all patients with discontinuation of topical anesthetic drug use along with adjunctive psychiatric treatment. Penetrating keratoplasty was performed in 2 patients. Toxic keratopathy due to topical anesthetic abuse is a curable disease. Early diagnosis and prevention of topical anesthetic drug use are the most important steps in the treatment of this condition. As these patients commonly exhibit psychiatric disorders, adjunctive psychiatric treatment may help to break the chemical addiction.

    As a member of the neurotrophic factor family, brain derived neurotrophic factor (BDNF) plays an important role in the survival and differentiation of neurons. The aim of our work was to evaluate the role of BDNF promoter methylation in drug addiction. A total of 60 drug abusers (30 heroin and 30 methylamphetamine addicts) and 52 healthy age- and gender-matched controls were recruited for the current case control study. Bisulfite pyrosequencing technology was used to determine the methylation levels of five CpGs (CpG1-5) on the BDNF promoter. Among the five CpGs, CpG5 methylation was significantly lower in drug abusers than controls. Moreover, significant associations were found between CpG5 methylation and addictive phenotypes including tension-anxiety, anger-hostility, fatigue-inertia, and depression-dejection. In addition, luciferase assay showed that the DNA fragment of BDNF promoter played a key role in the regulation of gene expression. Our results suggest that BDNF promoter methylation is associated with drug addiction, although further studies are needed to understand the mechanisms by which BDNF promoter methylation contributes to the pathophysiology of drug addiction.

    1987-01-01

    Lung and heart sections from 33 drug addicts submitted for medico-legal autopsy at the Institute of Forensic Medicine in Copenhagen were studied together with tissue sections from 20 'normal' persons. In the drug addict cases focal bleedings in lung tissue were found in 94%, signs of earlier bleedings, haemosiderin containing histiocytes, were seen in 91%, and focal fibrosis in 46%. The bleeding episodes may be due to hypoxia in connection with heroin intake. In 94% of the drug addicts birefringent material in lung tissue was demonstrated, in 58% in granulomas and giant cells, in 27% in giant cells only and in 9% in isolated histiocytes. The material was localized in the wall of pulmonar arteries and/or in the interstitial tissue, undoubtedly depending on the duration of the abuse. In 18% angiothrombosis was seen, in all cases granulomas/giant cells were observed in the wall of the vessel concerned. The results indicate periodical intravenous injection of dissolved tablets in addition to heroin. Histological signs of pulmonary hypertension were not seen, possibly due to the fact that abuse of central stimulants is very rare in Denmark. Regarding heart alterations no significant differences were demonstrated between drug addicts and controls. The only note-worthy finding was focal infiltration of lymphocytes in the atrio-ventricular bundle in two drug addicts, the meaning of which is uncertain.

    Drug addiction is a complex neurological dysfunction induced by recurring drug intoxication. Strategies to prevent and treat drug addiction constitute a topic of research interest. Early-stage romantic love is characterized by some characteristics of addiction, which gradually disappear as the love relationship progresses. Therefore, comparison of the concordance and discordance between romantic love and drug addiction may elucidate potential treatments for addiction. This focused review uses the evidences from our recent studies to compare the neural alterations between romantic love and drug addiction, moreover we also compare the behavioral and neurochemical alterations between romantic love and drug addiction. From the behavioral comparisons we find that there are many similarities between the early stage of romantic love and drug addiction, and this stage romantic love is considered as a behavioral addiction, while significant differences exist between the later stage of romantic love and drug addiction, and this stage of romantic love eventually developed into a prosocial behavior. The neuroimaging comparisons suggest that romantic love and drug addiction both display the functional enhancement in reward and emotion regulation network. Except the similar neural changes, romantic love display special function enhancement in social cognition network, while drug addiction display special dysfunction in cognitive control network. The neurochemical comparisons show that there are many similarities in the dopamine (DA) system, while significant differences in oxytocin (OT) system for romantic love and drug addiction. These findings indicate that the functional alterations in reward and emotion regulation network and the DA system may be the neurophysiological basis of romantic love as a behavioral addiction, and the functional alterations in social cognition network and the OT system may be the neurophysiological basis of romantic love as a prosocial behavior.

    Full Text Available Objective: This study was an attempt to compare cognitive functioning in substance abusers and addicts under methadone treatment with normal individuals. Method: The current study was a causal-comparative one. The statistical population of this research consisted of all male substance abusers who had referred to addiction treatment centers of Khoy city in 2013. The total of 40 addicts under methadone treatment, 40 active drug users, and 40 non-addicts were selected as the participants of this study via convenience sampling method. Wisconsin Card Sorting Test and Wechsler Memory Scale were administered to the three groups for data collection purposes. Results: The results showed that the substance abusers’ scores in Wisconsin card sorting test and Wechsler memory scale were significantly different from those of addicts under methadone treatment and normal individuals. In the same way, there was a significant difference between addicts under methadone treatment and normal individuals in terms of cognitive function however, there was no significant difference between these two groups in terms of perseveration error. Conclusion: It can be concluded that chronic use of psychoactive substances causes damage to multiple brain regions such as prefrontal cortex and hippocampus and, thereby, it leads to cognitive malfunctioning in these areas.

    Childhood maltreatment may lead to development of future substance use; however the contributions of a family history of substance use is unclear. To better understand the relationship between childhood abuse, family history of alcohol and drug abuse, and injecting drug use initiation in a cohort of chronic opioid users. A cross-sectional survey of long-term and difficult to treat intravenous opiate users of the North American Opiate Medication Initiative (NAOMI) cohort was conducted in two Canadian cities (Vancouver and Montreal). For the analysis, we selected a subsample (n = 87) of the population reported experiencing childhood abuse and completed a 12-month follow up. The sample was 41.4% female and 14.9% First Nations, with a mean age of 38 years. This sample then completed the Childhood Trauma Questionnaire (CTQ) and the Addiction Severity Index (ASI) beside others. Maternal alcohol and drug use was significantly associated with childhood sexual abuse, emotional abuse, and physical neglect. Paternal alcohol and drug use was significantly associated with childhood physical abuse. Increased severity of all types of childhood trauma was related to an earlier age of first injection. CONCLUSIONS/IMPORTANCE: Family history of drug and alcohol use is strongly associated with childhood trauma, which may, in turn, lead to an earlier initiation to the dangerous routes of drug injection.

    A quantitative epidemiological prevalence study of problem drug abuse in Sweden is the basis for a study of differences between drug abuse among men and women. A significant difference between genders was that, of those who come to the attention of the authorities, fewer women than men abuse drugs. The women were younger than the men. A greater percent of women abused amphetamines and injected heroin, as well as abusing tranquilizers/soporifics. A larger proportion of women than men were unemployed. The men had a significantly longer history of drug abuse than the women, a greater percent of them were born outside Sweden, and more of them had smoked heroin and used cannabis. A greater percent of the men had used illegal means to finance their abuse. There was a group of women (17%, median age 32) at the margins of the society, i.e. who had no work or place of residence, socialized solely with other addicts and financed their habit by illegal activities. Abuse of amphetamines and heroin was the most common. The majority of the women were polydrug abusers. Sweden has historically had, and continues to have, a large number of amphetamine abusers, but has now also developed a distinct population of heroin addicts.

    Kobayashi, Ohji

    2015-09-01

    In Japan, synthetic drugs have emerged since late 2000s, and cases of emergency visits and fatal traffic accidents due to acute intoxication have rapidly increased. The synthetic drugs gained popularity mainly because they were cheap and thought to be "legal". The Japanese government restricted not only production and distribution, but also its possession and use in April 2014. As the synthetic drug dependent patients have better social profiles compared to methamphetamine abusers, this legal sanction may have triggered the decrease in the number of synthetic drug dependent patient visits observed at Kanagawa Psychiatric Center since July 2014. Treatment of the synthetic drug dependent patients should begin with empathic inquiry into the motives and positive psychological effects of the drug use. In the maintenance phase, training patients to trust others and express their hidden negative emotions through verbal communications is essential. The recovery is a process of understanding the relationship between psychological isolation and drug abuse, and gaining trust in others to cope with negative emotions that the patients inevitably would face in their subsequent lives.

    Stigmatizing attitudes toward people with a drug addiction have detrimental effects on the lives of these people. However, the factors that influence stigma toward people with a drug addiction have not yet been thoroughly investigated, compared with the stigma of other mental illnesses. Based on attribution theory, our experiment examined to what extent individual and contextual characteristics of people with a drug addiction influence stigmatizing attitudes toward people with a drug addiction. Moreover, we explored whether respondent characteristics indicative of familiarity with addiction decrease stigma toward people with a drug addiction. We conducted a full factorial survey of 2,857 respondents from a German online access panel who were from all walks of life. We experimentally varied vignettes (2 9 -design) that featured a fictional person with an addiction. Stigmatizing beliefs, such as blame or fear, were assessed using the Attribution Questionnaire (AQ-9). Different attributes of people with a drug addiction and of the characteristics of their addiction modulated stigma in ways that are mostly consistent with attribution theory and related research. For example, female gender and younger age of people with a drug addiction diminished several stigmatizing attitudes; greater duration of addiction and social influence to use drugs increased them. Furthermore, characteristics of respondents modulated stigma: women, younger respondents, and those with higher education expressed less-stigmatizing responses than others. The stigmatization of people with a drug addiction is influenced by several factors, including characteristics of the stigmatized person, the addiction, and the person holding stigmatizing attitudes. A better understanding of the underlying mechanisms of these effects is needed to develop evidence-based antistigma measures.

    A pregnant adolescent's vulnerability increases when she is a victim of intrafamilial violence and drug addiction, which cause physical and biopsychosocial damage to the mother and her baby. Objective Present and analyze the case of an adolescent who is addicted to drugs, pregnant and the victim of lifelong intrafamilial violence. Method A case study based on a semi-structured interview conducted in the Obstetrics Emergency Unit at the Teaching Hospital of the University of São Paulo. The data were interpreted and analyzed using Content Analysis. Results intrafamilial violence experienced at the beginning of the adolescent's early relationships seriously affected her emotional maturity, triggering the development of psychopathologies and leaving her more susceptible to the use and abuse of alcohol and other drugs. The adolescent is repeating her history with her daughter, reproducing the cycle of violence. Conclusion Adolescent pregnancy combined with intrafamilial violence and drug addiction and multiplies the adolescent's psychosocial vulnerability increased the adolescent's vulnerability.

  1. The importance of the adenosine A(2A) receptor-dopamine D(2) receptor interaction in drug addiction.

    Filip, M; Zaniewska, M; Frankowska, M; Wydra, K; Fuxe, K

    2012-01-01

    Drug addiction is a serious brain disorder with somatic, psychological, psychiatric, socio-economic and legal implications in the developed world. Illegal (e.g., psychostimulants, opioids, cannabinoids) and legal (alcohol, nicotine) drugs of abuse create a complex behavioral pattern composed of drug intake, withdrawal, seeking and relapse. One of the hallmarks of drugs that are abused by humans is that they have different mechanisms of action to increase dopamine (DA) neurotransmission within the mesolimbic circuitry of the brain and indirectly activate DA receptors. Among the DA receptors, D(2) receptors are linked to drug abuse and addiction because their function has been proven to be correlated with drug reinforcement and relapses. The recognition that D(2) receptors exist not only as homomers but also can form heteromers, such as with the adenosine (A)(2A) receptor, that are pharmacologically and functionally distinct from their constituent receptors, has significantly expanded the range of potential drug targets and provided new avenues for drug design in the search for novel drug addiction therapies. The aim of this review is to bring current focus on A(2A) receptors, their physiology and pharmacology in the central nervous system, and to discuss the therapeutic relevance of these receptors to drug addiction. We concentrate on the contribution of A(2A) receptors to the effects of different classes of drugs of abuse examined in preclinical behavioral experiments carried out with pharmacological and genetic tools. The consequences of chronic drug treatment on A(2A) receptor-assigned functions in preclinical studies are also presented. Finally, the neurochemical mechanism of the interaction between A(2A) receptors and drugs of abuse in the context of the heteromeric A(2A)-D(2) receptor complex is discussed. Taken together, a significant amount of experimental analyses provide evidence that targeting A(2A) receptors may offer innovative translational strategies

    Drug abusers have access to new, more potent compounds that evade existing laws by virtue of their novel chemical structures. These drugs are available for purchase at stores and over the internet. The drugs are not illegal because they are so new that laws have not yet been passed to ban them. These drugs are leading to emergency department visits for cardiovascular, neurologic, and psychiatric complications. Standard drug screens are not designed to detect these new substances. The internet provides access to drugs for substance abusers but also provides physicians speed of access to the habits of substance abusers.

  4. Opioid Addiction and Abuse in Primary Care Practice: A Comparison of Methadone and Buprenorphine as Treatment Options

    Bonhomme, Jean; Shim, Ruth S.; Gooden, Richard; Tyus, Dawn; Rust, George

    2014-01-01

    Opioid abuse and addiction have increased in frequency in the United States over the past 20 years. In 2009, an estimated 5.3 million persons used opioid medications nonmedically within the past month, 200 000 used heroin, and approximately 9.6% of African Americans used an illicit drug. Racial and ethnic minorities experience disparities in availability and access to mental health care, including substance use disorders. Primary care practitioners are often called upon to differentiate between appropriate, medically indicated opioid use in pain management vs inappropriate abuse or addiction. Racial and ethnic minority populations tend to favor primary care treatment settings over specialty mental health settings. Recent therapeutic advances allow patients requiring specialized treatment for opioid abuse and addiction to be managed in primary care settings. The Drug Addiction Treatment Act of 2000 enables qualified physicians with readily available short-term training to treat opioid-dependent patients with buprenorphine in an office-based setting, potentially making primary care physicians active partners in the diagnosis and treatment of opioid use disorders. Methadone and buprenorphine are effective opioid replacement agents for maintenance and/or detoxification of opioid-addicted individuals. However, restrictive federal regulations and stigmatization of opioid addiction and treatment have limited the availability of methadone. The opioid partial agonist-antagonist buprenorphine/naloxone combination has proven an effective alternative. This article reviews the literature on differences between buprenorphine and methadone regarding availability, efficacy, safety, side-effects, and dosing, identifying resources for enhancing the effectiveness of medication-assisted recovery through coordination with behavioral/psychological counseling, embedded in the context of recovery-oriented systems of care.

  5. Reinforcement principles for addiction medicine; from recreational drug use to psychiatric disorder.

    Science.gov (United States)

    Edwards, Scott

    2016-01-01

    The transition from recreational drug use to addiction can be conceptualized as a pathological timeline whereby the psychological mechanisms responsible for disordered drug use evolve from positive reinforcement to favor elements of negative reinforcement. Abused substances (ranging from alcohol to psychostimulants) are initially ingested at regular occasions according to their positive reinforcing properties. Importantly, repeated exposure to rewarding substances sets off a chain of secondary reinforcing events, whereby cues and contexts associated with drug use may themselves become reinforcing and thereby contribute to the continued use and possible abuse of the substance(s) of choice. Indeed, the powerful reinforcing efficacy of certain drugs may eclipse that of competing social rewards (such as career and family) and lead to an aberrant narrowing of behavioral repertoire. In certain vulnerable individuals, escalation of drug use over time is thought to drive specific molecular neuroadaptations that foster the development of addiction. Research has identified neurobiological elements of altered reinforcement following excessive drug use that comprise within-circuit and between-circuit neuroadaptations, both of which contribute to addiction. Central to this process is the eventual potentiation of negative reinforcement mechanisms that may represent the final definitive criterion locking vulnerable individuals into a persistent state of addiction. Targeting the neural substrates of reinforcement likely represents our best chances for therapeutic intervention for this devastating disease. © 2016 Elsevier B.V. All rights reserved.

    2012-08-01

    Due to demographic changes there will be a fraction of elderly patients with substance use disorders. However, only a few data have been published about elderly abusers of prescription drugs. Since substance abuse is frequently comorbid with psychiatric disorders, treatment in a psychiatric hospital is often needed. In this explorative study elderly people with prescription drug abuse who required psychiatric inpatient treatment should be characterized. This study was part of the gerontopsychiatry study Berlin (Gepsy-B), an investigation of the data of all older inpatients (≥ 65 years) admitted to a psychiatric hospital within a period of 3 years. Among 1266 documented admissions in 110 cases (8.7 %) (mean age: 75.7 ± 7.1 years) prescription drug abuse, mostly of benzodiazepines was diagnosed. Females showed benzodiazepine abuse more often than males. In only a small proportion of the cases the reason for admission was withdrawal of prescribed drugs. 85.5 % suffered from psychiatric comorbidity, mostly depression. As risk factors for abuse depressive symptoms (OR: 3.32) as well as concurrent nicotine (OR: 2.69) or alcohol abuse (OR: 2.14) were calculated. Psychiatric inpatient treatment was primarily not necessary because of prescription drug abuse but because of other psychopathological symptoms. © Georg Thieme Verlag KG Stuttgart · New York.

  7. Neural Mechanisms of Reproduction in Females as a Predisposing Factor for Drug Addiction

    Science.gov (United States)

    Hedges, Valerie L.; Staffend, Nancy A.; Meisel, Robert L.

    2010-01-01

    There is an increasing awareness that adolescent females differ from males in their response to drugs of abuse and consequently in their vulnerability to addiction. One possible component of this vulnerability to drug addiction is the neurobiological impact that reproductive physiology and behaviors have on the mesolimbic dopamine system, a key neural pathway mediating drug addiction. In this review, we examine animal models that address the impact of ovarian cyclicity, sexual affiliation, sexual behavior, and maternal care on the long-term plasticity of the mesolimbic dopamine system. The thesis is that this plasticity in synaptic neurotransmission stemming from an individual’s normal life history contributes to the pathological impact of drugs of abuse on the neurobiology of this system. Hormones released during reproductive cycles have only transient effects on these dopamine systems, whereas reproductive behaviors produce a persistent sensitization of dopamine release and postsynaptic neuronal responsiveness. Puberty itself may not represent a neurobiological risk factor for drug abuse, but attendant behavioral experiences may have a negative impact on females engaging in drug use. PMID:20176045

  8. Does media coverage influence the spread of drug addiction?

    Ma, Mingju; Liu, Sanyang; Li, Jun

    2017-09-01

    In this paper, a three dimensional drug model is constructed to investigate the impact of media coverage on the spread and control of drug addiction. The dynamical behavior of the model is studied by using the basic reproduction number R0. The drug-free equilibrium is globally asymptotically stable if R0 drug addiction equilibrium is locally stable if R0 > 1. The results demonstrate that the media effect in human population cannot change the stabilities of equilibria but can affect the number of drug addicts. Sensitivity analyses are performed to seek for effective control measures for drug treatment. Numerical simulations are given to support the theoretical results.

    Full Text Available Objective: Having the information about pattern of substance abuse in the community and its epidemiological features is one of the most important protocols for evaluation, follow–up and control of the use of these substances. The aim of this study was to evaluate the patterns of substances abuse among narcotic anonymous (N. A. addicted patients. Materials & Methods: In this descriptive and analytical study, three hundred patients from narcotic abusers anonymous (N. A. association who were referred to a treatment center in Tehran were participated consecutively. The information about demographic characteristics, socioeconomic status, type of drug and the patterns of substance abuse of all cases were collected by researcher made questionnaire. Data were analyzed by Chi–Square test. Results: 80% of the patients were male. Almost 65. 2% of cases aged less than 40 years. More than two–third of cases had free jobs and 21. 2% of them were unemployed. Also, 32% of patients had college degrees. The most common types of abused substance were opium (88%, cigarette (76.7%, and alcohol (63% and 34% of them used substances intravenously. The use of alcohol (P=0.033, cannabis (P<0.001, cocaine (P=0.009 and ecstasy (P<0.001 was more prevalent significantly in the cases less than 40 years old than the elderly. Conclusion: It seems that the trend of substance abuse has been changed to younger population. The pattern of drug abuse in young adults is more toward psychosis drugs such as cocaine and ecstasy.

    Brain imaging techniques enable visualizing the activity of central nervous system without invasive neurosurgery. Dopamine is an important neurotransmitter. Its fluctuation in brain leads to a wide range of diseases and disorders, like drug addiction, depression, and Parkinson's disease. We designed near-infrared fluorescence dopamine-responsive nanoprobes (DRNs) for brain activity imaging during drug abuse and addiction process. On the basis of light-induced electron transfer between DRNs and dopamine and molecular wire effect of the DRNs, we can track the dynamical change of the neurotransmitter level in the physiological environment and the releasing of the neurotransmitter in living dopaminergic neurons in response to nicotine stimulation. The functional near-infrared fluorescence imaging can dynamically track the dopamine level in the mice midbrain under normal or drug-activated condition and evaluate the long-term effect of addictive substances to the brain. This strategy has the potential for studying neural activity under physiological condition.

    This study includes all deaths among drug addicts in the years 1991 (n = 219) and 1992 (n = 214) investigated at the three institutes of forensic medicine in Denmark. The results are compared with deaths among drug addicts in 1984-1985. The number of deaths among drug addicts increased by approximately 50% in 1991-1992 compared with 1984-1985. The increase was most significant among drug addicts over 35 years of age. The cause of death was intoxication in three-quarters of the cases in 1991-1992. In half of these cases heroin/morphine had caused death, while intoxications caused by methadone accounted for approximately 30% of the cases. In the metropolitan area the frequency of methadone intoxications increased significantly compared with 1984-1985, whereas the number of heroin/morphine intoxications did not change. Outside the metropolitan area, however, a significant increase in heroin/morphine intoxications was noticed. In all parts of the country the number of propoxyphene intoxications decreased to a few annual cases. The most commonly used drugs of abuse were heroin/morphine, diazepam and methadone, often in combination with alcohol.

    Difficulties in emotion regulation are commonly reported among individuals with alcohol and drug addictions and contribute to the acquisition and maintenance of addictive behaviors. Alterations in neural processing of negative affective stimuli have further been demonstrated among individuals with addictions. However, it is unclear whether these alterations are a general feature of addictions or are a result of prolonged exposure to drugs of abuse. To test the hypothesis of altered negative affect processing independent of drug effects, this study assessed neural function among drug-naïve youth with a behavioral addiction-Internet gaming disorder (IGD). Fifty-six young adults (28 with IGD, 28 matched controls) participated in fMRI scanning during performance of a well-validated emotion regulation task. Between-group differences in neural activity during task performance were assessed using a whole-brain, mixed-effects ANOVA with correction for multiple comparisons at currently recommended thresholds (voxel-level peffects.

    Drug addiction is a brain disorder that has negative consequences for individuals and society. Addictions are chronic relapsing diseases of the brain that are caused by direct drug-induced effects and persevering neuroadaptations at the epigenetic, neuropeptide and neurotransmitter levels. Because the dopaminergic system has a significant role in drug abuse, the purpose of this study was to analyze the methylation and expression profile of brain-derived neurotrophic factor (BDNF) and dopamine transporter (DAT1) genes in individuals with drug addiction. BDNF and DAT1 promoter methylation were investigated with a methylation-specific polymerase chain reaction (PCR) technique in blood samples from 75 individuals with drug addiction and 65 healthy controls. The expression levels of BDNF and DAT1 were assessed in 12 mRNA samples from the blood of patients and compared to the samples of healthy controls (n = 12) with real-time quantitative reverse transcription PCR. No significant differences were found in the methylation of BDNF and DAT1 between patients and controls, but the relative levels of expression of BDNF and DAT1 mRNA differed significantly in the patients compared to controls (p drug addiction.

    2015-01-01

    Alcohol abuse is comorbid with abuse of many other drugs, some with similar pharmacology and others quite different. This leads to the hypothesis of an underlying, unitary dysfunctional neurobiological basis for substance abuse risk and consequences. In this review, we discuss commonalities and distinctions of addiction to alcohol and other drugs. We focus on recent advances in pre-clinical studies using rodent models of drug self-administration. While there are specific behavioral and molecular manifestations common to alcohol, psychostimulant, opioid, and nicotine dependence, attempts to propose a unifying theory of the addictions inevitably face details where distinctions are found among classes of drugs. For alcohol, versus other drugs of abuse, we discuss and compare advances in: 1) neurocircuitry important for the different stages of drug dependence; 2) transcriptomics and genetical genomics; and 3) enduring effects. We note in particular the contributions of behavioral genetics and animal models: discussions of progress specifically relevant to treatment development can be found in the accompanying review (Karoly et al, this issue).

    The ability to adapt to environmental changes is an essential feature of biological systems, achieved in animals by a coordinated crosstalk between neuronal and hormonal programs that allow rapid and integrated organismal responses. Reward systems play a key role in mediating this adaptation by reinforcing behaviors that enhance immediate survival, such as eating or drinking, or those that ensure long-term survival, such as sexual behavior or caring for offspring. Drugs of abuse co-opt neuronal and molecular pathways that mediate natural rewards, which under certain circumstances can lead to addiction. Many factors can contribute to the transition from drug use to drug addiction, highlighting the need to discover mechanisms underlying the progression from initial drug use to drug addiction. Since similar responses to natural and drug rewards are present in very different animals, it is likely that the central systems that process reward stimuli originated early in evolution, and that common ancient biological principles and genes are involved in these processes. Thus, the neurobiology of natural and drug rewards can be studied using simpler model organisms that have their systems stripped of some of the immense complexity that exists in mammalian brains. In this paper we review studies in Drosophila melanogaster that model different aspects of natural and drug rewards, with an emphasis on how motivational states shape the value of the rewarding experience, as an entry point to understanding the mechanisms that contribute to the vulnerability of drug addiction.

    Full Text Available AIM: Since psychosocial characteristics of drug abuse involve mainly specific personality and emotional changes, it is very important to investigate characteristics of addictive personality in relationship with emotional state of the individual. Considering that, the objective of this study was to analyse the relationship between personality structure and emotional state of two different groups: heroin addicts and recreate drug abusers. METHODS: The total of 288 (219 males and 69 females; 191 heroin addicts and 97 recreate drug users clients of Centre for the prevention and treatment of drug abuse in Rijeka completed Eysenck's Personality Questionnaire (EPQ R/A, Beck's Anxiety Inventory (BAI and Beck's Depression Inventory (BDI. Their average age was 22. RESULTS: In the group of heroin addicts, higher levels of anxiety and depression were significantly correlated with higher levels of psychoticism, neuroticism, criminality and addiction. In the group of recreate drug users, higher extraversion and social conformity were determined. Furthermore, in the first group was found even higher depression. However when the anxiety level was compared between these two groups, there was no significant difference. CONCLUSION: Overall, the findings implied that the used measurement instruments could serve as the useful diagnostic tools that could ensure advantageous treatment directions.

    Chronic drug abuse is associated with elevated extracellular glutamate concentration in the brain reward regions. Deficit of glutamate clearance has been identified as a contributing factor that leads to enhanced glutamate concentration following extended drug abuse. Importantly, normalization of glutamate level through induction of glutamate transporter 1 (GLT1)/ excitatory amino acid transporter 2 (EAAT2) expression has been described in several in vivo studies. GLT1 upregulators including ceftriaxone, a beta-lactam antibiotic, have been effective in attenuating drug-seeking and drug-consumption behavior in rodent models. However, potential obstacles toward clinical translation of GLT1 (EAAT2) upregulators as treatment for drug addiction might include poor gastrointestinal absorption, serious peripheral adverse effects, and/or suboptimal CNS concentrations. Given the growing success of nanotechnology in targeting CNS ailments, nanoformulating known GLT1 (EAAT2) upregulators for selective uptake across the blood brain barrier presents an ideal therapeutic approach for treating drug addiction. In this review, we summarize the results obtained with promising GLT1 (EAAT2) inducing compounds in animal models recapitulating drug addiction. Additionally, the various nanoformulations that can be employed for selectively increasing the CNS bioavailability of GLT1 (EAAT2) upregulators are discussed. Finally, the applicability of GLT1 (EAAT2) induction via central delivery of drug-loaded nanoformulations is described.

    Clinical and preclinical findings indicate that males and females differ on several aspects of drug reinforcement. Females are more vulnerable than males during transition periods of drug use that are characteristic of drug addiction and relapse. Females are also more sensitive than males to the reinforcing effects of stimulants. It has been suggested that ovarian hormones contribute to the mechanisms of action underlying these sex differences. This review examines the preclinical literature on sex differences and ovarian hormonal influences on drug self-administration in animals. It summarizes the findings on the effects of these variables during different phases of drug addiction. Possible differences in the mechanisms of action of drugs of abuse due to interactions with sex differences or ovarian hormonal factors are considered. The animal literature on sex differences in drug abuse treatment effectiveness is also discussed.

    Phasic increases in brain dopamine are required for cue-directed reward seeking. Although compelling within the framework of appetitive behavior, the view that illicit drugs hijack reward circuits by hyperactivating these dopamine transients is inconsistent with established psychostimulant pharmacology. However, recent work reclassifying amphetamine (AMPH), cocaine, and other addictive dopamine-transporter inhibitors (DAT-Is) supports transient hyperactivation as a unifying hypothesis of abused drugs. We argue here that reclassification also identifies generating burst firing by dopamine neurons as a keystone action. Unlike natural rewards, which are processed by sensory systems, drugs act directly on the brain. Consequently, to mimic natural rewards and exploit reward circuits, dopamine transients must be elicited de novo. Of available drug targets, only burst firing achieves this essential outcome.

    Drug addiction shares common neurobiological pathways and risk genes with other psychiatric diseases, including psychosis. One of the commonly identified risk genes associated with broad psychosis has been ZNF804A. We sought to test whether psychosis risk variants in ZNF804A increase the risk of heroin addiction by modulating neurocognitive performance and gray matter volume (GMV) in heroin addiction. Using case-control genetic analysis, we compared the distribution of ZNF804A variants (genotype and haplotype) in 1035 heroin abusers and 2887 healthy subjects. We also compared neurocognitive performance (impulsivity, global cognitive ability and decision-making ability) in 224 subjects and GMV in 154 subjects based on the ZNF804A variants. We found significant differences in the distribution of ZNF804A intronic variants (rs1344706 and rs7597593) allele and haplotype frequencies between the heroin and control groups. Decision-making impairment was worse in heroin abusers who carried the ZNF804A risk allele and haplotype. Subjects who carried more risk alleles and haplotypes of ZNF804A had greater GMV in the bilateral insular cortex, right temporal cortex and superior parietal cortex. The interaction between heroin addiction and ZNF804A variants affected GMV in the left sensorimotor cortex. Our findings revealed several ZNF804A variants that were significantly associated with the risk of heroin addiction, and these variants affected decision making and GMV in heroin abusers compared with controls. The precise neural mechanisms that underlie these associations are unknown, which requires future investigations of the effects of ZNF804A on both dopamine neurotransmission and the relative increases in the volume of various brain areas. © 2015 Society for the Study of Addiction.

    The nucleus accumbens is a major input structure of the basal ganglia and integrates information from cortical and limbic structures to mediate goal-directed behaviors. Chronic exposure to several classes of drugs of abuse disrupts plasticity in this region, allowing drug-associated cues to engender a pathologic motivation for drug seeking. A number of alterations in glutamatergic transmission occur within the nucleus accumbens after withdrawal from chronic drug exposure. These drug-induced neuroadaptations serve as the molecular basis for relapse vulnerability. In this review, we focus on the role that glutamate signal transduction in the nucleus accumbens plays in addiction-related behaviors. First, we explore the nucleus accumbens, including the cell types and neuronal populations present as well as afferent and efferent connections. Next we discuss rodent models of addiction and assess the viability of these models for testing candidate pharmacotherapies for the prevention of relapse. Then we provide a review of the literature describing how synaptic plasticity in the accumbens is altered after exposure to drugs of abuse and withdrawal and also how pharmacological manipulation of glutamate systems in the accumbens can inhibit drug seeking in the laboratory setting. Finally, we examine results from clinical trials in which pharmacotherapies designed to manipulate glutamate systems have been effective in treating relapse in human patients. Further elucidation of how drugs of abuse alter glutamatergic plasticity within the accumbens will be necessary for the development of new therapeutics for the treatment of addiction across all classes of addictive substances.

    Many studies have provided evidence for important sex-dependent differences in the origins, outcomes and treatment of drug abuse and dependence. Preclinical studies typically have employed animal models of addiction, such as oral or intravenous self-administration, to untangle the environmental, neurobiological and genetic factors that contribute to the shift from occasional, recreational use to compulsive, uncontrolled intake of drugs. Craving and relapse of drug seeking in abstinent individuals have also been found to differ between men and women. Identification of the neurobiological basis of craving and drug dependence continues to pose a challenge to addiction research. Significant sex differences are emerging in substance-abuse-related behavior, which has increased the demand for research on how drug consumption may have different causes, progression and consequences in men and women. In keeping with epidemiological data in humans, differences between the two sexes in drug seeking and intake have been well-documented in animal studies, with most recent findings related to abuse of cannabinoids. Clinical and preclinical findings indicate that sex and gonadal hormones may account for individual differences in susceptibility to the reinforcing effects of addictive substances, and that differences in vulnerability to drug abuse may be mediated by the same biological mechanisms. This review focuses on the differences between males and females in relation to drug self-administration and how such behavior may be affected by hormonal status.

    2014-05-01

    Full Text Available Abstract Introduction: Addiction changes people from positive, active and healthy beings to consuming and negative patients. This study was carried out with the aim of determining the prevalence of the abuse of epioid substances among people referring to Yazd Addiction Diagnosis Laboratory using Rapid Test and Chromatography. Methods: In this descriptive cross-sectional study, all people who attended Yazd Addiction Diagnosis Laboratory for any reason, that is, marriage, employment or obtaining job license between 1386 and 1388, were examined. Totally, 2790 individuals were selected randomly. First, their demographic information was entered in the questionnaire. Then, urine samples were collected at the presence of a laboratory technician and tested using Ennissan Strip Rapid Test if the result was positive, the rest of the sample was tested with Chromatography. Results: Totally, 2790 individuals were surveyed in this study. The mean age of the participants was 25.9±7.2 years. About 62.9% were male and the rest were female. In addition, the reason for taking the test was marriage in 73.2%, employment in 15.5%, obtaining job license in 3.3% and other reasons for others. The prevalence of the abuse of opioid substances was 5.3% (95% CI 4.5% - 6.1%. Conclusions: Many test takers are aware of the fact that the result of the drug test becomes negative after three days of withdrawal, which might be the reason for the low prevalence of addiction in this study. However, prenuptial testing for addiction is quite prudent and necessary. Moreover, calculation of OR showed a male to female ratio of 15 to 1 for opioid abuse which was significant. Higher age, lower education level, labor work and working freelance, smoking and history of addiction in family were other risk factors for opioid substance abuse.

    Drug addiction takes a massive toll on society. Novel animal models are needed to test new treatments and understand the basic mechanisms underlying addiction. Rodent models have identified the neurocircuitry involved in addictive behavior and indicate that rodents possess some of the same neurobiologic mechanisms that mediate addiction in humans. Recent studies indicate that addiction is mechanistically and phylogenetically ancient and many mechanisms that underlie human addiction are also present in invertebrates. The nematode Caenorhabditis elegans has conserved neurobiologic systems with powerful molecular and genetic tools and a rapid rate of development that enables cost-effective translational discovery. Emerging evidence suggests that C. elegans is an excellent model to identify molecular mechanisms that mediate drug-induced behavior and potential targets for medications development for various addictive compounds. C. elegans emit many behaviors that can be easily quantitated including some that involve interactions with the environment. Ethanol (EtOH) is the best-studied drug-of-abuse in C. elegans and at least 50 different genes/targets have been identified as mediating EtOH's effects and polymorphisms in some orthologs in humans are associated with alcohol use disorders. C. elegans has also been shown to display dopamine and cholinergic system-dependent attraction to nicotine and demonstrate preference for cues previously associated with nicotine. Cocaine and methamphetamine have been found to produce dopamine-dependent reward-like behaviors in C. elegans. These behavioral tests in combination with genetic/molecular manipulations have led to the identification of dozens of target genes/systems in C. elegans that mediate drug effects. The one target/gene identified as essential for drug-induced behavioral responses across all drugs of abuse was the cat-2 gene coding for tyrosine hydroxylase, which is consistent with the role of dopamine neurotransmission

Cocaine and methamphetamine have been found to produce dopamine-dependent reward-like behaviors in C. elegans. These behavioral tests in combination with genetic/molecular manipulations have led to the identification of dozens of target genes/systems in C. elegans that mediate drug effects. The one target/gene identified as essential for drug-induced behavioral responses across all drugs of abuse was the cat-2 gene coding for tyrosine hydroxylase, which is consistent with the role of dopamine

    Translational molecular imaging with positron emission tomography (PET) and allied technologies offer unrivalled applications in the discovery of biomarkers and aetiological mechanisms relevant to human disease. Foremost among clinical PET findings during the past two decades of addiction research is the seminal discovery of reduced dopamine D(2/3) receptor expression in the striatum of drug addicts, which could indicate a predisposing factor and/or compensatory reaction to the chronic abuse of stimulant drugs. In parallel, recent years have witnessed significant improvements in the performance of small animal tomographs (microPET) and a refinement of animal models of addiction based on clinically relevant diagnostic criteria. This review surveys the utility of PET in the elucidation of neuropharmacological mechanisms underlying drug addiction. It considers the consequences of chronic drug exposure on regional brain metabolism and neurotransmitter function and identifies those areas where further research is needed, especially concerning the implementation of PET tracers targeting neurotransmitter systems other than dopamine, which increasingly have been implicated in the pathophysiology of drug addiction. In addition, this review considers the causal effects of behavioural traits such as impulsivity and novelty/sensation-seeking on the emergence of compulsive drug-taking. Previous research indicates that spontaneously high-impulsive rats--as exemplified by 'Zippy'--are pre-disposed to escalate intravenous cocaine self-administration, and subsequently to develop compulsive drug taking tendencies that endure despite concurrent adverse consequences of such behaviour, just as in human addiction. The discovery using microPET of pre-existing differences in dopamine D(2/3) receptor expression in the striatum of high-impulsive rats suggests a neural endophenotype that may likewise pre-dispose to stimulant addiction in humans. © 2011 The Authors.

    Full Text Available Abstract Background Recent epidemiological data show an increased trend of official estimates for syphilis infection in the general population. Many of the infected cases remain undetected leaving an underestimation of the true prevalence of syphilis in the general population, but also among subpopulations such as illicit drug users. There is limited epidemiological data published on the proportion and risk factors of syphilis infections associated with illicit drug abuse. Methods Illicit drug addicts (n = 1223 in inpatients units in Germany were screened (2000–01 for syphilis and interviewed regarding patterns of drug use and sexual behaviour. TPHA-test for initial screening and FTA-ABS-IgM test in TPHA-positive patients were used. Results In total, TPHA-tests were positive in 39 (3.3% and 7 patients (0.6% were IgM positive. The prevalence rate for syphilis in males was 1.9% and for women it was 8.5%. Female patients were 4.56 (CI 95% 2.37–8.78 times more likely to have a positive TPHA test than males. Sexual behaviours such as high number of sexual partners, sex for drugs/money, sex on the first day were associated with syphilis infection only in women. Females with frequent sex for drugs or money had 4.31 (CI 95% 2.32–8.52 times more likely a reactive TPHA test than remaining patients. Neither the sociodemographic factors nor sexual behaviour were statistically significant associated with syphilis infection among men at all. Conclusion Our data suggest the need for screening for syphilis among these illicit drug users in inpatient settings, in particular among sexual active women. This conclusion is corroborated by the finding of increasing numbers of syphilis infections in the general population. The identification of syphilis cases among drug addicts would give treatment options to these individuals and would help to reduce the spread of infection in this population, but also a spread into heterosexual populations related to

    The use of addictive drugs can have profound short- and long-term consequences on social behaviors. Similarly, social experiences and the presence or absence of social attachments during early development and throughout life can greatly influence drug intake and the susceptibility to drug abuse. The following review details this reciprocal interaction, focusing on common drugs of abuse (e.g., psychostimulants, opiates, alcohol and nicotine) and social behaviors (e.g., maternal, sexual, play, aggressive and bonding behaviors). The neural mechanisms underlying this interaction are discussed, with a particular emphasis on the involvement of the mesocorticolimbic dopamine system. Copyright © 2010 Elsevier Ltd.

    The growing rates of obesity have prompted comparisons between the uncontrolled intake of food and drugs; however, an evaluation of the equivalence of food- and drug-related behaviors requires a thorough understanding of the underlying neural circuits driving each behavior. Although it has been attractive to borrow neurobiological concepts from addiction to explore compulsive food seeking, a more integrated model is needed to understand how food and drugs differ in their ability to drive behavior. In this Review, we will examine the commonalities and differences in the systems-level and behavioral responses to food and to drugs of abuse, with the goal of identifying areas of research that would address gaps in our understanding and ultimately identify new treatments for obesity or drug addiction.

    This article examines some of the consequences of drug addiction in terms of family pathology and family disintegration. It briefly elucidates the role of the family in developing and maintaining drug addiction in family members. The concept of 'secondary' sufferers of the illness of drug addiction is examined. An actual case history will be presented in order to facilitate analysis of some of the forms of pathology and disintegration so often seen in the family of the drug addict. Within the family context, the question of who, if anyone, is the victim of drug addiction, is raised.

    Drug addiction and alcoholism involve a complex etiopathogenesis with a variable degree of risk contributions from the host (person), environment, and addictive substances. In this work, temperament and character features of individuals addicted to opiates or alcohol are compared with normal controls to study personality factors in the overall risk for drug addiction. The study was done in a permissive environment, with easy access to alcohol and heroin, which facilitated analyses of personality factors in drug choice. Participants included 412 consecutive patients (312 opiate addicts, 100 alcohol addicts) treated at the Specialized Hospital for Chemical Dependency in Belgrade, Serbia, and a community sample of 346 controls. Opiate addicts manifested antisocial temperament configuration (high Novelty Seeking, low Reward Dependence) coupled with high Self-transcendence (ie, susceptibility to fantasy and imagination). Alcohol addicts manifested sensitive temperament configuration (high Novelty Seeking coexisting with high Harm Avoidance). Immature personality was observed far more frequently in opiate addicts than in alcoholics or normals. Novelty Seeking appears to be a general risk factor for drug addiction. High Harm Avoidance appears to channel individuals with high Novelty Seeking towards alcoholism. Immature character traits and probable Personality Disorder increase the risk of illegal drugs. Based on equivalent research in nonpermissive environments, at least a portion of our opiate addicts could have developed alcoholism instead in environments with more limited access to opiates. Personality factors provide useful guidelines for preventive work with young individuals with personality risk factors for drug addiction. Copyright © American Academy of Addiction Psychiatry.

  4. Stress, habits, and drug addiction: a psychoneuroendocrinological perspective.

    It is well known that stress is a significant risk factor for the development of drug addiction and addiction relapse. Remarkably, the cognitive processes involved in the effects of stress on addictive behavior remain poorly understood. Here it is proposed that stress-induced changes in the neural circuits controlling instrumental action provide a potential mechanism by which stress affects the development of addiction and relapse vulnerability. Instrumental action can be controlled by two anatomically distinct systems: a goal-directed system that involves learning of action-outcome associations, and a habit system that learns stimulus-response associations. The transition from initial voluntary drug use to subsequent involuntary, compulsive drug use represents a switch from goal-directed to habitual control of action. Recent evidence indicates that this switch from goal-directed to habit action can be prompted by stress and stress hormones. We argue (i) that acute stressors reinstate habitual responding to drug-related cues and thus trigger relapse to addictive behavior, and (ii) that prolonged or repeated stress may accelerate the transition from voluntary to involuntary drug use and thus promote the development of addiction. The suggested mechanism encompasses cognitive processes that may contribute to the effects of stress on addictive behavior and could have important implications for the treatment of addiction and the prevention of relapse.

    Drug addiction is a disease that manifests as an inappropriate allocation of behavior towards the procurement and use of the abused substance and away from other behaviors that produce more adaptive reinforcers (e.g. exercise, work, family and social relationships). The goal of treating drug addiction is not only to decrease drug-maintained behaviors, but also to promote a reallocation of behavior towards alternative, nondrug reinforcers. Experimental procedures that offer concurrent access to both a drug reinforcer and an alternative, nondrug reinforcer provide a research tool for assessment of medication effects on drug choice and behavioral allocation. Choice procedures are currently the standard in human laboratory research on medications development. Preclinical choice procedures have been utilized in biomedical research since the early 1940's, and during the last 10-15 years, their use for evaluation of medications to treat drug addiction has increased. We propose here that parallel use of choice procedures in preclinical and clinical studies will facilitate translational research on development of medications to treat cocaine addiction. In support of this proposition, a review of the literature suggests strong concordance between preclinical effectiveness of candidate medications to modify cocaine choice in nonhuman primates and rodents and clinical effectiveness of these medications to modify either cocaine choice in human laboratory studies or metrics of cocaine abuse in patients with cocaine use disorder. The strongest evidence for medication effectiveness in preclinical choice studies has been obtained with maintenance on the monoamine releaser d -amphetamine, a candidate agonist medication for cocaine use analogous to use of methadone to treat heroin abuse or nicotine formulations to treat tobacco dependence.

    2009-01-01

    The past decade has witnessed an impressive accumulation of evidence indicating that the excitatory amino acid glutamate and its receptors, in particular the N-methyl-D-aspartate (NMDA) receptor subtype, play an important role in drug addiction. Various lines of research using animal models of drug addiction have demonstrated that drug-induced craving is accompanied by significant upregulation of NR2B subunit expression. Furthermore, selective blockade of NR2B-containing NMDA receptors in the striatum, especially in the nucleus accumbens (NAc) can inhibit drug craving and reinstatement. The purpose of this review is to examine the role of striatal NMDA receptors in drug addiction. After a brief description of glutamatergic innervation and NMDA receptor subunit distribution in the striatum, we discuss potential mechanisms to explain the role of striatal NMDA receptors in drug addiction by elucidating signaling cascades involved in the regulation of subunit expression and redistribution, phosphorylation of receptor subunits, as well as activation of intracellular signals triggered by drug experience. Understanding the mechanisms regulating striatal NMDA receptor changes in drug addiction will provide more specific and rational targets to counteract the deleterious effects of drug addiction.

    An increasingly important issue in the Polish population is drug abuse. It leads to extensive damage of parenchymal organs, including kidney. Establishing early markers of organ damage and their monitoring during rehabilitation therapy is therefore of pivotal importance. This study evaluated the utility of highly specific and selective markers (NGAL, IL-18, a and π-GST isoenzyme, and ß2-M). The influence of opioid drugs and other factors on kidney function (HIV and HCV infections, duration and the kind of drugs abused) was determined. Urine collected from 83 subjects who abused drugs and 33 healthy volunteers was tested with ELISA using specific antibodies (IBL, Biotron, Bioporto-Diagnostics). HIV infection was confirmed with western-blotting and HCV with PCR. CD4 lymphocytes were quantified with flow cytometry. RFLP and PCR were used to determine the viral load of HIV and HCV (genotype). A significant increase of IL-18, NGAL and β2M activity in heroin addicts compared to the control group was noted as well as the influence of HIV infection on NGAL and β2M excretion. A statistically significant (p=0.04) correlation between the viral load and IL-18 concentration was noted while no significant influence of the duration and the kind of drugs abused, the route of intake or the age of addicts was seen. Only the NGAL concentration was sex dependent and significantly higher in women. This study showed the specific, clinical utility of IL-18, NGAL, and β2M in the evaluation of renal function in drug addicts. Early detection of nephropathy with biochemical indicators might help prevent severe conditions that require hospitalization and intensive care.

    Full Text Available Background: Scholastic works suggest that those at risk for exercise addiction are also often addicted to illicit drugs, nicotine, and/or alcohol, but empirical evidence is lacking. Aims: The aim of the present work was to examine the co-occurrence of illicit drug, nicotine, and alcohol use frequency (prevalence of users and severity (level of problem in users among exercisers classified at three levels of risk for exercise addiction: (i asymptomatic, (ii symptomatic, and (iii at-risk. Methods: A sample of 538 regular exercisers were surveyed via the Qualtrics research platform. They completed the (i Drug Use Disorder Identification Test, (ii Fagerström Test for Nicotine Dependence, (iii Alcohol Use Disorder Identification Test, and (iv Exercise Addition Inventory. Results: A large proportion (n=59; 10.97% of the sample was found to be at risk for exercise addiction. The proportion of drug and alcohol users among these participants did not differ from the rest of the sample. However, the incidence of nicotine consumption was lowest among them. The severity of problematic substance use did not differ across the groups. Conclusions: These findings suggest that substance addiction and the risk for exercise addiction are unrelated. In fact, those at risk for exercise addiction exhibited the healthiest profile related to the prevalence of smoking.

    More than 80% of addicted individuals fail to seek treatment, which might reflect impairments in recognition of severity of disorder. Considered by some as intentional deception, such `denial' might instead reflect dysfunction of brain networks subserving insight and selfawareness. Here we review the scant literature on insight in addiction and integrate this perspective with the role of: (i) the insula in interoception, self-awareness and drug craving; (ii) the anterior cingulate in behavioral monitoring and response selection (relevant to disadvantageous choices in addiction); (iii) the dorsal striatum in automatic habit formation; and (iv) drug related stimuli that predict emotional behavior in addicted individuals, even without conscious awareness. We discuss implications for clinical treatment including the design of interventions to improve insight into illness severity in addiction. PMID:19716751

  16. Neurobiology of dysregulated motivational systems in drug addiction

    Edwards, Scott; Koob, George F

    2010-01-01

    The progression from recreational drug use to drug addiction impacts multiple neurobiological processes and can be conceptualized as a transition from positive to negative reinforcement mechanisms driving both drug-taking and drug-seeking behaviors. Neurobiological mechanisms for negative reinforcement, defined as drug taking that alleviates a negative emotional state, involve changes in the brain reward system and recruitment of brain stress (or antireward) systems within forebrain structures, including the extended amygdala. These systems are hypothesized to be dysregulated by excessive drug intake and to contribute to allostatic changes in reinforcement mechanisms associated with addiction. Points of intersection between positive and negative motivational circuitry may further drive the compulsivity of drug addiction but also provide a rich neurobiological substrate for therapeutic intervention.

    2001-01-01

    This study was undertaken to determine differences in previous treatment patterns in individuals currently using different numbers of substances. Medical records of 1198 inpatient detoxification (detox) admissions were analyzed. Numbers of past admissions to completed detox, methadone, or other types of drug abuse treatment were totaled and ranked to determine most frequent type. Within gender, treatment histories of single and multiple drug abusers usually do not differ. The one exception is male multiple drug abusers ages 26-30, who show increased admissions. Possible explanations are that men do not seek treatment before developing medical complications of addiction or until external factors influence admission. There were differences in treatment histories between genders in multiple drug abusers only. Before age 30, women reported increased treatment of certain types. Possible explanations are that treatment priority is given to women who are, or may be, pregnant. Also, younger men may not enter or complete treatment. Previous treatment history may influence many behaviors. The results of this study delineate several valuable indicators for assessing past history.

    2008-01-01

    Addiction research has historically neglected research on women, and most studies have been conducted on men only, with the concluding results generalized to the female population. The role of sex differences in vulnerability to drug abuse, their repercussions on prevention and treatment strategies all require detailed studies, as does the progression from recreational drug use to dependence. This review synthesizes evidence of gender differences in drug addiction, with particular emphasis on women's health and implications. We first reviewed behavioral studies showing sex differences in the preference for and self-administration of licit (i.e., alcohol and nicotine) and illicit (i.e., cocaine, amphetamine, heroin and cannabis) substances as revealed by animal models of addiction. Clinical studies demonstrating differences between men and women in craving, drug use, abstinence and relapse will then be examined. For both animal and human studies, the effects of hormones and estrous/menstrual cycle will be reviewed. Finally, neurobiological factors underlying gender differences in vulnerability to drug addiction (i.e., brain morphology and neurotransmission) and need for gender-specific detoxification treatments will be discussed.

    Montoya, Iván D.

    2008-01-01

    Immunotherapies in the form of vaccines (active immunization) or monoclonal antibodies (passive immunization) appear safe and a promising treatment approaches for some substance-related disorders. The mechanism of action of the antibody therapy is by preventing the rapid entry of drugs of abuse into the central nervous system. In theory, immunotherapies could have several clinical applications. Monoclonal antibodies may be useful to treat drug overdoses and prevent the neurotoxic effects of drugs by blocking the access of drugs to the brain. Vaccines may help to prevent the development of addiction, initiate drug abstinence in those already addicted to drugs, or prevent drug use relapse by reducing the pharmacological effects and rewarding properties of the drugs of abuse on the brain. Passive immunization with monoclonal antibodies has been investigated for cocaine, methamphetamine, nicotine, and phencyclidine (PCP). Active immunization with vaccines has been studied for cocaine, heroin, methamphetamine, and nicotine. These immunotherapies seem promising therapeutic tools and are at different stages in their development before they can be approved by regulatory agencies for the treatment of substance-related disorders. The purpose of this article is to review the current immunotherapy approaches with emphasis on the risks and benefits for the treatment of these disorders. PMID:18551223

    The purpose of the study was to develop a scale for measuring the recovery in self-help program for drug addicts. Our study sites were fourteen self-help groups for drug addicts called "DARC: Drug Addiction Rehabilitation Center". DARC activities were based on Narcotics Anonymous types of self-help program. The 25-items DASH-scale questionnaire was developed using data, which were obtained through in-depth interview among DARC staff. A cross-sectional study among recovering addicts participating in "DARC" activities was implemented from Jan 2004 to Feb 2004. 164 subjects were responded to our questionnaire. Factor analysis was carried out and items with weaker or split loadings were removed. Factor analysis of DASH-scale results produced a surprisingly clean four-factor solution. 19-items were left to form the final DASH-scale; regular life-style (6 items), acceptance of drug addiction (5 items), sympathy with member (5 items), reborn (3 items). The internal consistency (Cronbach's Alpha) of these scales was very high (0.87). Low but significant concurrent correlations were observed between the DASH-scale and the Rosenberg Self-Esteem Scale (0.22), Purpose in Life Test (0.35). Discriminant validity of the DASH-scale was supported by significant increase with exposed period of self-help program. Evidence supports the DASH-scale was possible to measure recovery in self-help program.

  1. The dopamine hypothesis of drug addiction and its potential therapeutic value.

    Directory of Open Access Journals (Sweden)

    Marco eDiana

    2011-11-01

    Full Text Available Dopamine (DA transmission is deeply affected by drugs of abuse, and alterations in DA function are involved in various phases of drug addiction and potentially exploitable therapeutically. In particular, basic studies have documented a reduction in the electrophysiological activity of DA neurons in alcohol, opiate, cannabinoid and other drug-dependent rats. Further, DA release in the Nacc is decreased in virtually all drug-dependent rodents. In parallel, these studies are supported by increments in intracranial self stimulation (ICSS thresholds during withdrawal from alcohol, nicotine, opiates, and other drugs of abuse, thereby suggesting a hypofunction of the neural substrate of ICSS. Accordingly, morphological evaluations fed into realistic computational analysis of the Medium Spiny Neuron (MSN of the Nucleus accumbens (Nacc, post-synaptic counterpart of DA terminals, show profound changes in structure and function of the entire mesolimbic system. In line with these findings, human imaging studies have shown a reduction of dopamine receptors accompanied by a lesser release of endogenous DA in the ventral striatum of cocaine, heroin and alcohol-dependent subjects, thereby offering visual proof of the ‘dopamine-impoverished’ addicted human brain.The reduction in physiological activity of the DA system leads to the idea that an increment in its activity, to restore pre-drug levels, may yield significant clinical improvements (reduction of craving, relapse and drug-seeking/taking. In theory, it may be achieved pharmacologically and/or with novel interventions such as Transcranial Magnetic Stimulation (TMS. Its anatomo-physiological rationale as a possible therapeutic aid in alcoholics and other addicts will be described and proposed as a theoretical framework to be subjected to experimental testing in human addicts.

    The idea that addiction occurs when the brain is not able to differentiate whether specific reward circuits were triggered by adaptive natural rewards or falsely activated by addictive drugs exist in several models of drug addiction. The suitability of crayfish ( Orconectes rusticus ) for drug addiction research arises from developmental variation of growth, life span, reproduction, behavior and some quantitative traits, especially among isogenic mates reared in the same environment. This broad spectrum of traits makes it easier to analyze the effect of mammalian drugs of abuse in shaping behavioral phenotype. Moreover, the broad behavioral repertoire allows the investigation of self-reinforcing circuitries involving appetitive and exploratory motor behavior, while the step-wise alteration of the phenotype by metamorphosis allows accurate longitudinal analysis of different behavioral states. This paper reviews a series of recent experimental findings that evidence the suitability of crayfish as an invertebrate model system for the study of drug addiction. Results from these studies reveal that unconditioned exposure to mammalian drugs of abuse produces a variety of stereotyped behaviors. Moreover, if presented in the context of novelty, drugs directly stimulate exploration and appetitive motor patterns along with molecular processes for drug conditioned reward. Findings from these studies indicate the existence of drug sensitive circuitry in crayfish that facilitates exploratory behavior and appetitive motor patterns via increased incentive salience of environmental stimuli or by increasing exploratory motor patterns. This work demonstrates the potential of crayfish as a model system for research into the neural mechanisms of addiction, by contributing an evolutionary, comparative context to our understanding of natural reward as an important life-sustaining process.

Moreover, the broad behavioral repertoire allows the investigation of self-reinforcing circuitries involving appetitive and exploratory motor behavior, while the step-wise alteration of the phenotype by metamorphosis allows accurate longitudinal analysis of different behavioral states. This paper reviews a series of recent experimental findings that evidence the suitability of crayfish as an invertebrate model system for the study of drug addiction. Results from these studies reveal that unconditioned exposure to mammalian drugs of abuse produces a variety of stereotyped behaviors. Moreover, if presented in the context of novelty, drugs directly stimulate exploration and appetitive motor patterns along with molecular processes for drug conditioned reward. Findings from these studies indicate the existence of drug sensitive circuitry in crayfish that facilitates exploratory behavior and appetitive motor patterns via increased incentive salience of environmental stimuli or by increasing exploratory motor patterns. This work demonstrates the potential of crayfish as a model system for research into the neural mechanisms of addiction, by contributing an evolutionary, comparative context to our understanding of natural reward as an important life-sustaining process.

    This study aimed to determine whether selected superabsorbent polymers (SAPs) could be used as a suitable alternative to thwart extraction, filtration, and syringeability attempts for abuse. Many abuse-deterrent formulations (ADFs) rely on high molecular weight polymers such as poly(ethylene oxide) to provide crush and extraction resistance. However, these polymers suffer from slow dissolution kinetics, and are susceptible to a variety of abuse conditions. Several commercially available SAPs were evaluated for swelling behavior in extraction solvents, and tableting properties. Post-compaction abuse properties were evaluated by recoverable volume and syringeability after solvent extraction. Drug release and percent drug extraction were conducted using tramadol HCl as a model drug. Certain SAPs had the ability to rapidly imbibe solvent and effectively stop extraction processes in a variety of solvents, including water and water/alcohol mixtures. Tablets containing SAP and drug showed no effect on drug release in vitro. SAPs possess adequate properties for tableting, and maintain their high and fast swelling properties after compaction. The fast and extensive interactions of SAPs with aqueous medium are a major advantage over non-crosslinked high molecular weight viscosifying agents such as poly(ethylene oxide).

    The aim of this study was to assess knowledge, attitudes and practice towards HIV/AIDS among alcohol and drug abusers and the effect of health education (HE) on their knowledge and attitudes. Participants were 265 substance abusers, recruited from 8 addiction rehabilitation centers. A base line study preceding HE was done using a questionnaire composed of five sections. Three scores were developed to assess HIV/AIDS related knowledge. The base line study indicates that addicts with good knowledge scores > or =75%) regarding modes of transmission were significantly higher among males than females. About 70% of the addicts had negative attitudes towards dealing with HIV/AIDS patients, while 55.5% felt sympathy for them. Eleven percent of the injection drug abusers were sharing needle with others, while 38% of the participating females were previously convicted of prostitution. Logistic analysis showed that high level of education was the best predictive variable for good knowledge scores (> or =75%). Evaluation of the health education program revealed a highly significant increase in the knowledge scores among both males and females compared to the pretest scores. An increase in the percentages of male and female addicts with improved attitudes towards HIV/AIDS patients was also noted after HE. So, HE was found to be a successful tool in improving the knowledge and attitudes of substance abusers towards HIV/AIDS.

    In Singapore, the treatment and rehabilitation of drug addicts consist of detoxification, recuperation and orientation, indoctrination, physical training and work programme. This is followed by a Day Release Scheme to bridge the gap between the strict disciplinary regime and the free environment of the outside world. The addicts are given the opportunities to pursue academic studies. Two review committees monitor their progress. There has been a significant decrease in the total number of admission from 7084 in 1977 to 2043 in 1982. Over this period, there appears to be a drop in the number of youths recruited into drug abuse. At the same time, more and more of those who have been previously treated are coming into the drug scene.

    Abuse of designer drugs is widespread among young people, especially in the so-called "dance club scene" or "rave scene", worldwide. Severe and even fatal poisonings have been attributed to the consumption of such drugs of abuse. However, in contrast to new medicaments, which are extensively studied in controlled clinical studies concerning metabolism, including cytochrome P450 isoenzyme differentiation, and further pharmacokinetics, designer drugs are consumed without any safety testing. This paper reviews the metabolism of new designer drugs of abuse that have emerged on the black market during the last years. Para-methoxyamphetamine (PMA), para-methoxymethamphetamine (PMMA) and 4-methylthioamphetamine (4-MTA), were taken into consideration as new "classical" amphetamine-derived designer drugs. Furthermore, N-benzylpiperazine (BZP), 1-(3, 4-methylenedioxybenzyl)piperazine (MDBP), 1-(3-trifluoromethylphenyl)piperazine (TFMPP), 1-(3-chlorophenyl)piperazine (mCPP) and 1-(4-methoxyphenyl)piperazine (MeOPP) were taken into consideration as derivatives of the class of piperazine-derived designer drugs, as well as alpha-pyr-rolidinopropiophenone (PPP), 4'-methoxy-alpha-pyrrolidinopropiophenone (MOPPP), 3', 4'-methylenedioxy-alpha-pyrrolidino-propiophenone (MDPPP), 4'-methyl-alpha-pyrrolidinopropiophenone (MPPP), and 4'-methyl-alpha-pyrrolidinoexanophenone (MPHP) as derivatives of the class of alpha-pyrrolidinophenone-derived designer drugs. Papers describing identification of in vivo or in vitro human or animal metabolites and cytochrome P450 isoenzyme dependent metabolism have been considered and summarized.

    Children's emotional and relational development can be negatively influenced by maternal substance abuse, particularly through a dysfunctional caregiving environment. Attachment Theory offers a privileged framework to analyze how drug addiction can affect the quality of adult attachment style, parenting attitudes and behaviors toward the child, and how it can have a detrimental effect on the co-construction of the attachment bond by the mother and the infant. Several studies, as a matter of fact, have identified a prevalence of insecure patterns among drug-abusing mothers and their children. Many interventions for mothers with Substance Use Disorders have focused on enhancing parental skills, but they have often overlooked the emotional and relational features of the mother-infant bond. Instead, in recent years, a number of protocols have been developed in order to strengthen the relationship between drug-abusing mothers and their children, drawing lessons from Attachment Theory. The present study reviews the literature on the adult and infant attachment style in the context of drug addiction, describing currently available treatment programs that address parenting and specifically focus on the mother-infant bond, relying on Attachment Theory.

    Full Text Available Objective: To report the self-perception of substance-abusing individuals who were in a recovery process regarding sociodemographic conditions and general and oral health. Methods: Descriptive cross-sectional study conducted in a recovery center for drug addiction in Alfenas, Minas Gerais, Brazil, in 2015, with 39 men aged over 18 years old. Data were collected using a semi-structured questionnaire that addressed: socioeconomic status, selfperception of general and oral health, access to dental care, relationship with the dentist, and other issues. In order to assess the self-perception of oral health, the variable was dichotomized into “satisfactory” and “unsatisfactory”, which refer to what the individual acknowledges as a good or poor condition of oral health, using Fisher’s exact test with 5% significance level. Results: Most frequent diseases were depression, 35.90% (n=14, insomnia, 35.9%, (n=14 and recurring headache (23.1%; n=9; however, 61.50% (n=24 of the participants reported not getting sick easily, which contrasts with their self-perception. Regarding oral health, only 30.50% (n=12 of the participants reported brushing their teeth three times a day; 53.80% (n=21 had dentinal hypersensitivity; 41.00% (n=16 had dry mouth and bad breath; 30.80% (n=12 claimed to have bruxism and reported having one or more loose teeth; 28.20% (n=11 reported clenching the teeth in an exaggerated way, and 33.30% (n=13 reported feeling tooth pain. Conclusion: The self-perception of individuals – under 30 years old, single, white or mulattos – regarding their general health was contradictory, as they rated it as good but have reported depression, insomnia and weight loss; additionally, oral health was considered poor with unsatisfactory conditions, which highlights the harmful effects of substance abuse.

    Kandall, Stephen R

    2010-04-01

    The history of women and addiction in America extends back more than 150 years. Although the true epidemiology of women and addiction has always been difficult to determine, the spectrum of female addicts extends well beyond those women who make sensationalistic headlines by "abandoning" or "battering" their children. Historically, female addiction has been largely the result of inappropriate overmedication practices by physicians and pharmacists, media manipulation, or individuals own attempts to cope with social or occupational barriers preventing equality and self-fulfillment. From the mid-nineteenth century, uneasy tolerance, social ostracism, vilification, persecution, and legal prosecution have grudgingly, but not completely, given way to more humane treatment opportunities in the setting of more enlightened comprehensive care.

  16. Treatment approaches for interoceptive dysfunctions in drug addiction.

    Science.gov (United States)

    Paulus, Martin P; Stewart, Jennifer L; Haase, Lori

    2013-10-18

    There is emerging evidence that individuals with drug addiction have dysfunctions in brain systems that are important for interoceptive processing, which include, among others, the insular and the anterior cingulate cortices. These individuals may not be expending sufficient neural resources to process perturbations of the interoceptive state but may exert over-activation of these systems when processing drug-related stimuli. As a consequence, insufficient detection and processing of interoceptive state changes may result in inadequate anticipation and preparation to adapt to environmental challenges, e.g., adapt to abstinence in the presence of withdrawal symptoms. Here, we integrate interoceptive dysfunction in drug-addicted individuals, with the neural basis for meditation and exercise to develop a heuristic to target the interoceptive system as potential treatments for drug addiction. First, it is suggested that mindfulness-based approaches can modulate both interoceptive function and insular activation patterns. Second, there is an emerging literature showing that the regulation of physical exercise in the brain involves the insula and anterior cingulate cortex and that intense physical exercise is associated with a insula changes that may provide a window to attenuate the increased interoceptive response to drug-related stimuli. It is concluded that the conceptual framework of interoceptive dysfunctions in drug addiction and the experimental findings in meditation and exercise provide a useful approach to develop new interventions for drug addiction.

    2015-12-01

    Full Text Available Cannabinoids (Δ9-tetrahydrocannabinol are the active ingredient of marijuana (cannabis which is the most commonly abused illicit drug in the USA. In addition to being known and used as recreational drugs, cannabinoids are produced endogenously by neurons in the brain (endocannabinoids and serve as important signaling molecules in the nervous system and the rest of the body. Cannabinoids have been implicated in bodily processes both in health and disease. Recent pharmacological and physiological experiments have described novel aspects of classic brain signaling mechanisms or revealed unknown mechanisms of cellular communication involving the endocannabinoid system. While several forms of signaling have been described for endocannabinoids, the most distinguishing feature of endocannabinoids is their ability to act as retrograde messengers in neural circuits. Neurons in the main olfactory bulb express high levels of cannabinoid receptors. Here, we describe the cellular mechanisms and function of this novel brain signaling system in regulating neural activity at synapses in olfactory circuits. Results from basic research have the potential to provide the groundwork for translating the neurobiology of drug abuse to the realm of the pharmacotherapeutic treatment of addiction, specifically marijuana substance use disorder.

    Beckley, Jacob T; Woodward, John J

    2013-12-01

    Volatile solvents such as those found in fuels, paints, and thinners are found throughout the world and are used in a variety of industrial applications. However, these compounds are also often intentionally inhaled at high concentrations to produce intoxication. While solvent use has been recognized as a potential drug problem for many years, research on the sites and mechanisms of action of these compounds lags behind that of other drugs of abuse. In this review, we first discuss the epidemiology of voluntary solvent use throughout the world and then consider what is known about their basic pharmacology and how this may explain their use as drugs of abuse. We next present data from preclinical and clinical studies indicating that these substances induce common addiction sequelae such as dependence, withdrawal, and cognitive impairments. We describe how toluene, the most commonly studied psychoactive volatile solvent, alters synaptic transmission in key brain circuits such as the mesolimbic dopamine system and medial prefrontal cortex (mPFC) that are thought to underlie addiction pathology. Finally, we make the case that activity in mPFC circuits is a critical regulator of the mesolimbic dopamine system's ability to respond to volatile solvents like toluene. Overall, this review provides evidence that volatile solvents have high abuse liability because of their selective effects on critical nodes of the addiction neurocircuitry, and underscores the need for more research into how these compounds induce adaptations in neural circuits that underlie addiction pathology.

    The dopamine D3 receptor is located in the limbic area and apparently mediates selective effects on motivation to take drugs and drug-seeking behaviors, so that there has been considerable interest on the possible use of D3 receptor ligands to treat drug addiction. However, only recently selective tools allowing studying this receptor have been developed. This chapter presents an overview of findings that were presented at a symposium on the conference Dopamine 2013 in Sardinia in May 2013. Novel neurobiological findings indicate that drugs of abuse can lead to significant structural plasticity in rodent brain and that this is dependent on the availability of functional dopamine D3 autoreceptor, whose activation increased phosphorylation in the ERK pathway and in the Akt/mTORC1 pathway indicating the parallel engagement of a series of intracellular signaling pathways all involved in cell growth and survival. Preclinical findings using animal models of drug-seeking behaviors confirm that D3 antagonists have a promising profile to treat drug addiction across drugs of abuse type. Imaging the D3 is now feasible in human subjects. Notably, the development of (+)-4-propyl-9-hydroxynaphthoxazine ligand used in positron emission tomography (PET) studies in humans allows to measure D3 and D2 receptors based on the area of the brain under study. This PET ligand has been used to confirm up-regulation of D3 sites in psychostimulant users and to reveal that tobacco smoking produces elevation of dopamine at the level of D3 sites. There are now novel antagonists being developed, but also old drugs such as buspirone, that are available to test the D3 hypothesis in humans. The first results of clinical investigations are now being provided. Overall, those recent findings support further exploration of D3 ligands to treat drug addiction. © 2014 Elsevier B.V.

    2014-07-01

    The mammalian (or mechanistic) target of rapamycin (mTOR) complex 1 (mTORC1) is a serine and threonine kinase that regulates cell growth, survival, and proliferation. mTORC1 is a master controller of the translation of a subset of mRNAs. In the central nervous system mTORC1 plays a crucial role in mechanisms underlying learning and memory by controlling synaptic protein synthesis. Here, we review recent evidence suggesting that the mTORC1 signaling pathway promotes neuroadaptations following exposure to a diverse group of drugs of abuse including stimulants, cannabinoids, opiates, and alcohol. We further describe potential molecular mechanisms by which drug-induced mTORC1 activation may alter brain functions. Finally, we propose that mTORC1 is a focal point shared by drugs of abuse to mediate drug-related behaviors such as reward seeking and excessive drug intake, and offer future directions to decipher the contribution of the kinase to mechanisms underlying addiction. Recent studies suggesting that exposure to diverse classes of drugs of abuse as well as exposure to drug-associated memories lead to mTORC1 kinase activation in the limbic system. In turn, mTORC1 controls the onset and the maintenance of pathological neuroadaptions that underlie several features of drug addiction such as drug seeking and relapse. Therefore, we propose that targeting mTORC1 and its effectors is a promising strategy to treat drug disorders. © 2014 International Society for Neurochemistry.

    The rising toll of opioid overdoses in the past decade has been declared a prescription drug epidemic by the Centers for Disease Control. In that same period, Internet platforms, such as Facebook and Twitter, have grown exponentially, being used primarily by a population similar to new initiates of substance abuse. Researchers have utilized social media to gain insights into use patterns and prevailing attitudes about various substances. Social media has potential to enhance screening, prevention, and treatment of addiction. With future funding, they should be leveraged to advance understanding of prescription drug use and improve treatment and prevention of abuse.

    Full Text Available Background. Parenteral drug abuse is the most common cause of infected femoral artery pseudoaneurysms (IFAP. This complication of intravenous drug abuse is not only limb threatening but can also be life threatening. The management of the IFAP is difficult and controversial. Generally speaking, ligation and excision of the pseudoaneurysm without revascularization is accepted procedure in majority of the patients. However it is not regarded as an appropriate procedure for cases where the high probability of amputation is expected from acute interruption of the femoral artery flow.Patients, methods and results. We present three cases of young (average 20 years, range 18–24 patients with IFAP, in which a primary reconstruction was performed due to absence of doppler signal over pedal arteries after ligation of common femoral artery. In two of them complications in form of haemorrhage and repeated infection developed in late postoperative period. The first one, had an excision and ligation while the second one had a reconstruction made by means of a silver impregnated dacron prosthesis. None of the patients required an amputation.Conclusions. Overall prognosis and prognosis of the reconstruction in parenteral drug abuse patients is uncertain because there is a high incidence of postoperative drug injection despite aggressive drug rehabilitation.

  10. Neuroimaging Impaired Response Inhibition and Salience Attribution in Human Drug Addiction: A Systematic Review.

    2018-06-06

    The impaired response inhibition and salience attribution (iRISA) model proposes that impaired response inhibition and salience attribution underlie drug seeking and taking. To update this model, we systematically reviewed 105 task-related neuroimaging studies (n > 15/group) published since 2010. Results demonstrate specific impairments within six large-scale brain networks (reward, habit, salience, executive, memory, and self-directed networks) during drug cue exposure, decision making, inhibitory control, and social-emotional processing. Addicted individuals demonstrated increased recruitment of these networks during drug-related processing but a blunted response during non-drug-related processing, with the same networks also being implicated during resting state. Associations with real-life drug use, relapse, therapeutic interventions, and the relevance to initiation of drug use during adolescence support the clinical relevance of the results. Whereas the salience and executive networks showed impairments throughout the addiction cycle, the reward network was dysregulated at later stages of abuse. Effects were similar in alcohol, cannabis, and stimulant addiction. Copyright © 2018 Elsevier Inc. All rights reserved.

    2013-01-01

    Drug addictions remain a substantial health issue, with limited treatment options currently available. Despite considerable advances in the understanding of our genetic architecture, the genetic underpinning of complex disorders remains elusive. Numerous candidate genes have been implicated in the etiology and response to treatment for different addictions based on our current understanding of the neurobiology. Genome-wide association studies have also provided novel targets. However, replication of these studies is often lacking which complicates interpretation; this will improve as issues such as phenotypic characterization, the apparent “missing heritability”, the identification of functional variants, and possible gene-environment interactions are addressed. In addition, there is growing evidence that genetic information can be useful for refining the choice of addiction treatment. As genetic testing becomes more common in the practice of medicine, a variety of ethical and practical challenges, some of which are unique to drug addiction, will also need to be considered.

    Impairments in response inhibition and salience attribution (iRISA) have been proposed to underlie the clinical symptoms of drug addiction as mediated by cortico-striatal-thalamo-cortical networks. The bulk of evidence supporting the iRISA model comes from neuroimaging research that has focused on cortical and striatal influences with less emphasis on the role of the thalamus. Here, we highlight the importance of the thalamus in drug addiction, focusing on animal literature findings on thalamic nuclei in the context of drug-seeking, structural and functional changes of the thalamus as measured by imaging studies in human drug addiction, particularly during drug cue and non-drug reward processing, and response inhibition tasks. Findings from the animal literature suggest that the paraventricular nucleus of the thalamus, the lateral habenula and the mediodorsal nucleus may be involved in the reinstatement, extinction and expression of drug-seeking behaviours. In support of the iRISA model, the human addiction imaging literature demonstrates enhanced thalamus activation when reacting to drug cues and reduced thalamus activation during response inhibition. This pattern of response was further associated with the severity of, and relapse in, drug addiction. Future animal studies could widen their field of focus by investigating the specific role(s) of different thalamic nuclei in different phases of the addiction cycle. Similarly, future human imaging studies should aim to specifically delineate the structure and function of different thalamic nuclei, for example, through the application of advanced imaging protocols at higher magnetic fields (7 Tesla).This article is part of a discussion meeting issue 'Of mice and mental health: facilitating dialogue between basic and clinical neuroscientists'. © 2018 The Author(s).

    Immunotherapy has a great potential of becoming a new therapeutic strategy in the treatment of addiction to psychoactive drugs. It may be used to treat addiction but also to prevent neurotoxic complications of drug overdose. In preclinical studies two immunological methods have been tested; active immunization, which relies on the administration of vaccines and passive immunization, which relies on the administration of monoclonal antibodies. Until now researchers have succeeded in developing vaccines and/or antibodies against addiction to heroin, cocaine, methamphetamine, nicotine and phencyclidine. Their effectiveness has been confirmed in preclinical studies. At present, clinical studies are being conducted for vaccines against nicotine and cocaine and also anti-methamphetamine monoclonal antibody. These preclinical and clinical studies suggest that immunotherapy may be useful in the treatment of addiction and drug overdose. However, there are a few problems to be solved. One of them is controlling the level of antibodies due to variability between subjects. But even obtaining a suitable antibody titer does not guarantee the effectiveness of the vaccine. Additionally, there is a risk of intentional or unintentional overdose. As vaccines prevent passing of drugs through the blood/brain barrier and thereby prevent their positive reinforcement, some addicted patients may erroneously seek higher doses of psychoactive substances to get "high". Consequently, vaccination should be targeted at persons who have a strong motivation to free themselves from drug dependency. It seems that immunotherapy may be an opportunity for effective treatment of drug addiction if directed to adequate candidates for treatment. For other addicts, immunotherapy may be a very important element supporting psycho- and pharmacotherapy. Copyright © 2015 Elsevier Ltd. All rights reserved.

  15. Recent updates on drug abuse analyzed by neuroproteomics studies: Cocaine, Methamphetamine and MDMA

    Full Text Available Currently, drug abuse and addiction represent a global public health concern with about 13.6 million people using illicit drugs in the USA alone. Substance abuse intervenes in normal brain functioning, causing alterations in memory, behavior and neuronal physiology. Although many studies have been conducted to elucidate the mode of action of different drugs, the heterogeneous modes of drug intake led to a complicated profile of drug-induced brain changes involving neurotoxicity and addiction. Given the complex interplay of genes and proteins in mediating these effects, neuroproteomics analysis has been considered among the methods of choice to complement what has already been discovered and to create targeted therapies. In this review, we will focus on three drugs, namely cocaine, methamphetamine (METH and 3,4-methylenedioxy-N-methylamphetamine (MDMA. In the context of neuroproteomics, these drugs have been extensively studied by utilizing different experimental models, including primate and non-primate animals along with postmortem human samples. Even though there are many variations in the results, these drugs were shown to employ common pathways in eliciting their effects. Neuroproteomics analysis of these drugs has led to the identification of differentially expressed proteins involved in metabolism, oxidative stress, cell signaling, cytoskeleton, cell death and synaptic plasticity. Finally, this work will discuss recent findings from our laboratory by looking at a model of chronic methamphetamine abuse and its effect on different brain regions.

    Full Text Available Objective . We present the clinical, biochemical, and imaging findings of a woman with vitamin D deficiency and severe osteomalacia related to intravenous heroin addiction. Results . A 54-year-old woman with a medical history significant for long-standing heroin abuse presented with complaints of bone pain, muscle cramping, and a left hip ulcer. She had been bed bound for approximately 1 year secondary to pain of uncertain etiology, and her husband was bringing her both food and drugs. She was admitted to the hospital for debridement of a right ischial ulcer. Further workup revealed osteomyelitis of the left hip and severe vitamin D deficiency. Radiologic evaluation demonstrated diffuse osteopenia with pseudofractures, as well as true fractures. Conclusion . This is the first case reported in the English literature of advanced osteomalacia resulting from a debilitating narcotic dependency. Vitamin D deficiency should be considered in patients with poor nutrition and prolonged sunlight deprivation from any cause.

  17. Developing a coordinated response to drug abuse in Pakistan.

    2010-03-01

    This paper describes moves towards the coordination of efforts to respond to the worsening drug abuse situation in Pakistan which affects all segments of society. The efforts reported seek to rectify inconsistencies in treatment policy resulting in unsatisfactory outcomes. Examples of collaborative strategies with encouraging results need further underpinning and expansion. There is, however, a lack of realization at the policy level of the need to effect changes in treatment formulated on a consistent and evidence-based approach. Policy has therefore been reviewed and proposals made for a comprehensive treatment strategy in line with international best practices to deal with this problem effectively and efficiently. Establishment of an addiction study centre at university level to continue professional and academic development is suggested.

  18. Behavioral characteristics and neurobiological substrates shared by Pavlovian sign-tracking and drug abuse.

    Tomie, Arthur; Grimes, Kathryn L; Pohorecky, Larissa A

    2008-06-01

    Drug abuse researchers have noted striking similarities between behaviors elicited by Pavlovian sign-tracking procedures and prominent symptoms of drug abuse. In Pavlovian sign-tracking procedures, repeated paired presentations of a small object (conditioned stimulus, CS) with a reward (unconditioned stimulus, US) elicits a conditioned response (CR) that typically consists of approaching the CS, contacting the CS, and expressing consummatory responses at the CS. Sign-tracking CR performance is poorly controlled and exhibits spontaneous recovery and long-term retention, effects that resemble relapse. Sign-tracking resembles psychomotor activation, a syndrome of behavioral responses evoked by addictive drugs, and the effects of sign-tracking on corticosterone levels and activation of dopamine pathways resemble the neurobiological effects of abused drugs. Finally, the neurobiological profile of individuals susceptible to sign-tracking resembles the pathophysiological profile of vulnerability to drug abuse, and vulnerability to sign-tracking predicts vulnerability to impulsive responding and alcohol self-administration. Implications of sign-tracking for models of drug addiction are considered.

    Full Text Available Background and Aim: Statistics show that 30% to 40 % of  opium addicted fathers’ children are prone to substance abuse in the future. The present study aimed at assessing the effectiveness of cognitive therapy approach  to attitude changing of adolescents with substance dependent fathers. Materials and Methods:  In this controlled. field-trail randomized study. .data collection tool was “attitude to addiction questionnaire”. The study population was all male students in the first grade of high school in Maneh - Samalghan city. . Six sessions of group cognitive therapy based on the effectiveness of drug side-effects in drug-addicted fathers’ adolescent children’s attitude were held. The above-mentioned questionnaire was filled out before and after intervention. The obtained data  was fed into SPSS software (V: 16 using. Independent t-test .and paired t-test were used for analysis and P<0.05 was taken as the significant level. Results:  There were no significant differences between the two groups in pre-test regarding their attitude about drug abuse (P=.20%. Mean score variance from pre-test to post-test in the intervention group decreased, but in the control group, it showed a slight increase. This means that the intervention reduced the positive attitude towards drugs, but the changes were not statistically significant (p=0.57. Besides, among ten factors decisive in an individual’s attitude about addiction, only group cognitive therapy  was able  to decrease mean points of an individual’s attitude about drug abuse .. Significantly (P = 0.04. Conclusion: It was found that group cognitive therapy education about opium  addict complicationsdidn`t have a significant effect on the attitude of the students with addicted fathers. Thus, a change of adolescents’ attitude requires more research.

  3. Fischer 344 and Lewis Rat Strains as a Model of Genetic Vulnerability to Drug Addiction.

    Cadoni, Cristina

    2016-01-01

    Today it is well acknowledged that both nature and nurture play important roles in the genesis of psychopathologies, including drug addiction. Increasing evidence suggests that genetic factors contribute for at least 40-60% of the variation in liability to drug dependence. Human genetic studies suggest that multiple genes of small effect, rather than single genes, contribute to the genesis of behavioral psychopathologies. Therefore, the use of inbred rat strains might provide a valuable tool to identify differences, linked to genotype, important in liability to addiction and related disorders. In this regard, Lewis and Fischer 344 inbred rats have been proposed as a model of genetic vulnerability to drug addiction, given their innate differences in sensitivity to the reinforcing and rewarding effects of drugs of abuse, as well their different responsiveness to stressful stimuli. This review will provide evidence in support of this model for the study of the genetic influence on addiction vulnerability, with particular emphasis on differences in mesolimbic dopamine (DA) transmission, rewarding and emotional function. It will be highlighted that Lewis and Fischer 344 rats differ not only in several indices of DA transmission and adaptive changes following repeated drug exposure, but also in hypothalamic-pituitary-adrenal (HPA) axis responsiveness, influencing not only the ability of the individual to cope with stressful events, but also interfering with rewarding and motivational processes, given the influence of corticosteroids on dopamine neuron functionality. Further differences between the two strains, as impulsivity or anxiousness, might contribute to their different proneness to addiction, and likely these features might be linked to their different DA neurotransmission plasticity. Although differences in other neurotransmitter systems might deserve further investigation, results from the reviewed studies might open new vistas in understanding aberrant

    Full Text Available The main aim of this study is to investigate the influence of dissociative experiences and alcohol/drugs dependence on Internet addiction. From a clinical point of view Internet addiction, an excessive or poorly controlled preoccupation, urges, and/or behaviors regarding Internet use, lead to emotional and social problems in several life domains. Moreover, the increased prevalence of Internet addiction among adolescents and young adults is cause of concerns. Data was collected on 441 undergraduate students (285 female, aging from 18 to 36, using an assessment self-reporting set consisting of the Young’s Internet Addiction Test, the Leeds Dependence Questionnaire and the Dissociative Experience Scale. Results converging for the three psychological phenomena involved are interrelated, corroborating the hypothesis of the search for an altered state of consciousness as their common underlying mechanism. Findings show that the tendency to escape from reality, through dissociation and substance abuse, are risk factors for Internet addiction in youngsters. The implications of these results are discussed in a preventive and clinical perspective.

    Most of the researches in Pakistan are concerned with the aetiological factors of drug addiction among the youth. However, few studies seek to explore the social aspects of this phenomenon. The present study aimed to explore the role of family, the influence of parental involvement, and communication styles in youth's drug addiction in a qualitative manner. Twenty drug addicts (age range 18-28 years) were taken as a sample from drug rehabilitation centres in Rawalpindi and Islamabad, Pakistan. A structured interview guide was administered comprising questions related to the individual's habits, relationship with family and friends, and modes of communication within the family. Case profiles of the participants were also taken. The rehabilitation centres offered family therapy and the researcher, as a non-participant, observed these sessions as part of the analysis. The demographic information revealed that majority of the participants were poly-substance abusers (80%) and the significant reasons for starting drugs were the company of peers and curiosity. The thematic analysis revealed parental involvement and emotional expressiveness as two major components in family communication. It was found that parents were concerned about their children, but were not assertive in the implementation of family rules. It was also found that the major life decisions of the participants were taken by their parents, which is a characteristic of collectivist Pakistani society.

  8. Studying the relationship between the styles of attachment, drug addiction and psychological profile of addicts in comparison with non-addicts (in self-introduced centers of Bushehr Province

    Directory of Open Access Journals (Sweden)

    2004-05-01

    Full Text Available Emphasizing on effective factors in drug dependency and multiple drug relapse, is probably related to formation of personality models. These models are heavily affected by development orientation personality. Various researches show that attachment as a development factor has a decisive role in forming personality models. Hence, in one hand, the present research evaluates the relationship between attachment styles and drug dependency and ,in the other hand, it addresses the relationship between attachment /drug addiction and psychological profile. The statistical community of this research consists of all male referrals to self-introduced centers in Bushehr province in summer 1381. The sample group consists 100 individuals of this community and comparison group cnosists another 100 individuals who had no history of drug abuse. They were controlled by counterpart variables. The tools of this research are MCMI-II and adults’ attachment questionnaire. The satisfaction of validity and reliabilty of research literature are reported. Apllied statistical methods include χ² statistical test and profile analysis. To compare the individual distribution based on attachment style, χ² test is obtained meaningfully in P<0/05 level. Also, the results of profile analysis for evaluating the effect of drug addiction and attachment style on psychological profile is meaningful in P<0/01 level. In summary, the research shows that there is a relationship between attachment style and drug addiction as well as between attachment/addiction and psychological profile.

    Addiction is a chronic brain disorder. Prolonged abstinence from drugs of abuse involves dysphoria, high stress responsiveness and craving. The neurobiology of drug abstinence, however, is poorly understood. We previously identified a unique set of hundred mu-opioid receptor-dependent genes in the extended amygdala, a key site for hedonic and stress processing in the brain. Here we examined these candidate genes either immediately after chronic morphine, nicotine, Δ9-tetrahydrocannabinol or alcohol, or following 4 weeks of abstinence. Regulation patterns strongly differed among chronic groups. In contrast, gene regulations strikingly converged in the abstinent groups and revealed unforeseen common adaptations within a novel huntingtin-centered molecular network previously unreported in addiction research. This study demonstrates that, regardless the drug, a specific set of transcriptional regulations develops in the abstinent brain, which possibly contributes to the negative affect characterizing protracted abstinence. This transcriptional signature may represent a hallmark of drug abstinence and a unitary adaptive molecular mechanism in substance abuse disorders. © 2011 The Authors, Addiction Biology © 2011 Society for the Study of Addiction.

  10. Role of the dopamine transporter in the action of psychostimulants, nicotine, and other drugs of abuse.

    Zhu, J; Reith, M E A

    2008-11-01

    A number of studies over the last two decades have demonstrated the critical importance of dopamine (DA) in the behavioral pharmacology and addictive properties of abused drugs. The DA transporter (DAT) is a major target for drugs of abuse in the category of psychostimulants, and for methylphenidate (MPH), a drug used for treating attention deficit hyperactivity disorder (ADHD), which can also be a psychostimulant drug of abuse. Other drugs of abuse such as nicotine, ethanol, heroin and morphine interact with the DAT in more indirect ways. Despite the different ways in which drugs of abuse can affect DAT function, one evolving theme in all cases is regulation of the DAT at the level of surface expression. DAT function is dynamically regulated by multiple intracellular and extracellular signaling pathways and several protein-protein interactions. In addition, DAT expression is regulated through the removal (internalization) and recycling of the protein from the cell surface. Furthermore, recent studies have demonstrated that individual differences in response to novel environments and psychostimulants can be predicted based on individual basal functional DAT expression. Although current knowledge of multiple factors regulating DAT activity has greatly expanded, many aspects of this regulation remain to be elucidated; these data will enable efforts to identify drugs that might be used therapeutically for drug dependence therapeutics.

    Inappropriate use of analgesic drugs has become increasingly pervasive over the past decade. Currently, drug abuse potential is primarily assessed post-marketing; no validated tools are available to assess this potential in phase II and III clinical trials. This paper describes the development and feasibility testing of a Misuse, Abuse, and Diversion Drug Event Reporting System (MADDERS), which aims to identify potentially abuse-related events and classify them according to a recently developed classification scheme, allowing the quantification of these events in clinical trials. The system was initially conceived and designed with input from experts and patients, followed by field-testing to assess its feasibility and content validity in both completed and ongoing clinical trials. The results suggest that MADDERS is a feasible system with initial validity. It showed higher rates of the triggering events in subjects taking medications with known abuse potential than in patients taking medications without abuse potential. Additionally, experts agreed on the classification of most abuse-related events in MADDERS. MADDERS is a new systematic approach to collect information on potentially abuse-related events in clinical trials and classify them. The system has demonstrated feasibility for implementation. Additional research is ongoing to further evaluate its validity. Currently, there are no validated tools to assess drug abuse potential during clinical trials. Because of its ease of implementation, its systematic approach, and its preliminary validation results, MADDERS could provide such a tool for clinical trials.

    2012-12-01

    The steady increase of new drugs of abuse on the illicit drug market is a great challenge for analytical toxicologists. Because most of these new drugs or drug classes are not included in established analytical methods targeting classic drugs of abuse, analytical procedures must be adapted or new procedures must be developed to cover such new compounds. This review summarizes procedures for analysis of these drugs of abuse published from January 2009 to January 2012 covering the following classes of emerging drugs of abuse as follows: β-keto-amphetamines, pyrrolidinophenones, tryptamines, and synthetic cannabinoids.

    Full Text Available The intention of this article is to demonstrate, within the framework of cognitive linguistics (Lakoff and Johnson, 1980a, how slang words associated with substance abuse are conceptualized via metaphors. This study analyses recreational drug slang terms found in the Drug Slang Dictionary in order to reveal categories of metaphors involved in drug users’ language. The results of the data analysis effectively reveal that, within a thematic approach, classes of metaphor are coded to enable connections between metaphorical concepts and drug addicts’ physiological experiences in order to present their personal meanings and cognitive processes. The study also involves drug addicts’ narratives to identify conceptual metaphors in their experiences. Notably, it is argued within this research that figurative language use is also connected to the cultural background of users to a great extent.

  15. Post-training amphetamine administration enhances memory consolidation in appetitive Pavlovian conditioning: Implications for drug addiction.

    Simon, Nicholas W; Setlow, Barry

    2006-11-01

    It has been suggested that some of the addictive potential of psychostimulant drugs of abuse such as amphetamine may result from their ability to enhance memory for drug-related experiences through actions on memory consolidation. This experiment examined whether amphetamine can specifically enhance consolidation of memory for a Pavlovian association between a neutral conditioned stimulus (CS-a light) and a rewarding unconditioned stimulus (US-food), as Pavlovian conditioning of this sort plays a major role in drug addiction. Male Long-Evans rats were given six training sessions consisting of 8 CS presentations followed by delivery of the food into a recessed food cup. After the 1st, 3rd, and 5th session, rats received subcutaneous injections of amphetamine (1.0 or 2.0 mg/kg) or saline vehicle immediately following training. Conditioned responding was assessed using the percentage of time rats spent in the food cup during the CS relative to a pre-CS baseline period. Both amphetamine-treated groups showed significantly more selective conditioned responding than saline controls. In a control experiment, there were no differences among groups given saline, 1.0 or 2.0 mg/kg amphetamine 2 h post-training, suggesting that immediate post-training amphetamine enhanced performance specifically through actions on memory consolidation rather than through non-mnemonic processes. This procedure modeled Pavlovian learning involved in drug addiction, in which the emotional valence of a drug reward is transferred to neutral drug-predictive stimuli such as drug paraphernalia. These data suggest that amphetamine may contribute to its addictive potential through actions specifically on memory consolidation.

    Full Text Available Abstract Background and objective: NAS is a combination of signs and symptoms that due to physical and mental dependency, develops in neonates born from drug addicted mothers. The onset of NAS varies in accordance with the type, amount, frequency and duration of substance used. Because of diverse and unclear pattern of substance abuse in Iranian addicted pregnant mothers in comparison with western countries, this multi-center study has been designed to evaluate NAS in neonates born from drug addicted mothers. Material and method: A cross sectional study was carried out on newborns of narcotic addicted mothers during the first six months of 2008. The newborn’s status and clinical signs were checked by physical examination and scored by the Finnegan scoring system. Results: In this study 100 neonates born from narcotic addicted mothers were examined; the most used narcotic was crack (36%. 60% of neonates showed signs of NAS. The most prevalent signs of NAS were increased muscle tonicity (60%/7, irritability (59%/6 and increased moro reflex (51%/8. Neonates born from crack abusers, in comparison with other drugs, were significantly at risk of NAS (100% vs.87%, p

    2015-11-01

    New drugs of abuse continue to emerge, including synthetic cannabinoids, synthetic cathinones, and hallucinogens. It is important to recognize their individual psychopharmacologic properties, symptoms of intoxication, and symptoms of withdrawal.

    2004-04-01

    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. Counsel individuals who are concerned about drug use by a loved one. 8. Counsel individuals who are concerned about their own drug use

    The persistence of the motivational salience of drug-related environmental cues and contexts is one of the most problematic obstacles to successful treatment of drug addiction. Behavioral approaches to extinguishing the salience of drug-associated cues, such as cue exposure therapy, have generally produced disappointing results which have been attributed to, among other things, the context specificity of extinction and inadequate consolidation of extinction learning. Extinction of any behavio...

      This study aims to estimate the prevalence of drug use by pregnant women living in Ibiza, using structured interviews and biomarkers in maternal hair. In addition, the potentially detrimental effects of maternal drug abuse on their newborns were investigated. Ibiza has a large international night-life resort associated with clubs, music and use of recreational drugs.   Hair samples were collected prospectively from January to March 2010 from a cohort of consecutive mothers after giving birth in the Hospital Can Misses in Ibiza.   Opiates, cocaine, cannabis, methadone, amphetamines, 3,4-methylenedioxymethamphetamine (MDMA) and their metabolites were detected in a 3-cm-long proximal segment of maternal hair corresponding to the last trimester of pregnancy by gas chromatography coupled to mass spectrometry (n = 107). Data on socio-demographic characteristics and on tobacco, alcohol, drugs of prescription and drugs of abuse consumption during pregnancy were collected using a structured questionnaire.   Hair analysis showed an overall 16% positivity for drugs of abuse in the third trimester of pregnancy, with a specific prevalence of cannabis, cocaine, MDMA and opiates use of 10.3, 6.4, 0.9 and 0%, respectively. In the questionnaires, only 1.9% of mothers declared using drugs of abuse during pregnancy. Gestational drug of abuse consumption was associated with active tobacco smoking, a higher number of smoked cigarettes and the mother being Spanish.   Illicit drug use is substantially under-reported among pregnant women living in Ibiza, particularly among Spanish nationals. Voluntary, routine objective biological toxicology screening should be considered as part of routine examinations in antenatal clinics on this Mediterranean island. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

    Drug use among patients with bipolar disorder is greater than the one observed in the general population; psychotic episodes are likely to occur after consumption. This has implications in the prevention, etiology, management, and treatment of the disease. Bipolar disorder pathology is likely to have positive response to pharmacological treatment. Therefore, identifying the strategies with better results to be applied in these patients is fundamental for psychiatrists and primary care physicians. Review literature in order to determine the prevalence and characteristics of drug abuse in patients with bipolar disorder and establish the pharmacological strategies that have produced better results. Literature review. A great variety of studies demonstrate the relationship between bipolar disorder and drug use disorder. These patients are hospitalized more frequently, have an earlier onset of the disease, and present a larger number of depressive episodes and suicide attempts which affect the course of the disease. The drug with better results in the treatment of these patients is Divalproate. Satisfactory results have been also obtained with other mood stabilizers such as carbamazepine, lamotrigine, and the antipsychotic aripiprazole. Substance abuse is present in a large number of patients with bipolar disorder. The Divalproate is the drug that has shown better results in the studies.

  7. Biological basis of sex differences in drug abuse: preclinical and clinical studies.

    Lynch, Wendy J; Roth, Megan E; Carroll, Marilyn E

    2002-11-01

    The recent focus on drug abuse in women has brought attention to numerous differences between women and men. In this review, we discuss both preclinical and clinical findings of sex differences in drug abuse as well as mechanisms that may underlie these differences. Recent evidence suggests that the progression to dependence and abuse may differ between women and men; thus, different prevention and treatment strategies may be required. Similar sex differences in drug sensitivity and self-administration have been reported in laboratory animal studies. Females appear to be more vulnerable than males to the reinforcing effects of psychostimulants, opiates, and nicotine during many phases of the addiction process (e.g. acquisition, maintenance, dysregulation-escalation, relapse). Male and female animals differ in their behavioral, neurological, and pharmacological responses to drugs. Although the role of sex in the mechanisms of drug action remains unclear, preclinical and clinical studies indicate that ovarian hormones, particularly estrogen, play a role in producing sex differences in drug abuse. Future research is necessary to provide information on how to design more effective drug abuse treatment programs and resources that are sex specific.

    Heroin and methylamphetamine (METH) are two addictive drugs that cause serious problems for society. Dopamine receptor D4 (DRD4), a key receptor in the dopaminergic system, may facilitate the development of drug addiction. The aim of the present study was to investigate the association between the promoter methylation level of DRD4 gene and drug addiction. Bisulfite pyrosequencing technology was used to measure the methylation levels of DRD4 promoter in 60 drug addicts and 52 matched controls. Significantly higher levels of DRD4 CpG1 and CpG4 methylation were detected in METH and heroin drug addicts compared with controls (Pdrug addiction.

  9. Stress- and glucocorticoid-induced priming of neuroinflammatory responses: potential mechanisms of stress-induced vulnerability to drugs of abuse.

    Frank, Matthew G; Watkins, Linda R; Maier, Steven F

    2011-06-01

    Stress and stress-induced glucocorticoids (GCs) sensitize drug abuse behavior as well as the neuroinflammatory response to a subsequent pro-inflammatory challenge. Stress also predisposes or sensitizes individuals to develop substance abuse. There is an emerging evidence that glia and glia-derived neuroinflammatory mediators play key roles in the development of drug abuse. Drugs of abuse such as opioids, psychostimulants, and alcohol induce neuroinflammatory mediators such as pro-inflammatory cytokines (e.g. interleukin (IL)-1β), which modulate drug reward, dependence, and tolerance as well as analgesic properties. Drugs of abuse may directly activate microglial and astroglial cells via ligation of Toll-like receptors (TLRs), which mediate the innate immune response to pathogens as well as xenobiotic agents (e.g. drugs of abuse). The present review focuses on understanding the immunologic mechanism(s) whereby stress primes or sensitizes the neuroinflammatory response to drugs of abuse and explores whether stress- and GC-induced sensitization of neuroimmune processes predisposes individuals to drug abuse liability and the role of neuroinflammatory mediators in the development of drug addiction.

  10. The affective dimension of pain as a risk factor for drug and alcohol addiction.

    Science.gov (United States)

    LeBlanc, Dana M; McGinn, M Adrienne; Itoga, Christy A; Edwards, Scott

    2015-12-01

    Addiction, or substance use disorder (SUD), is a devastating psychiatric disease composed of multiple elemental features. As a biobehavioral disorder, escalation of drug and/or alcohol intake is both a cause and consequence of molecular neuroadaptations in central brain reinforcement circuitry. Multiple mesolimbic areas mediate a host of negative affective and motivational symptoms that appear to be central to the addiction process. Brain stress- and reinforcement-related regions such as the central amygdala (CeA), prefrontal cortex (PFC), and nucleus accumbens (NAc) also serve as central processors of ascending nociceptive input. We hypothesize that a sensitization of brain mechanisms underlying the processing of persistent and maladaptive pain contributes to a composite negative affective state to drive the enduring, relapsing nature of addiction, particularly in the case of alcohol and opioid use disorder. At the neurochemical level, pain activates central stress-related neuropeptide signaling, including the dynorphin and corticotropin-releasing factor (CRF) systems, and by this process may facilitate negative affect and escalated drug and alcohol use over time. Importantly, the widespread prevalence of unresolved pain and associated affective dysregulation in clinical populations highlights the need for more effective analgesic medications with reduced potential for tolerance and dependence. The burgeoning epidemic of prescription opioid abuse also demands a closer investigation into the neurobiological mechanisms of how pain treatment could potentially represent a significant risk factor for addiction in vulnerable populations. Finally, the continuing convergence of sensory and affective neuroscience fields is expected to generate insight into the critical balance between pain relief and addiction liability, as well as provide more effective therapeutic strategies for chronic pain and addiction.

    Given the recent interest in the concept of sexual addictions, it is instructive to study subjects with pedophilia alongside chemically addicted individuals and non-addicted controls in order to help identify which factors may determine the objects of people's respective addictions, as well as any factors that may predispose people to developing an addictive disorder. In this study, we considered whether childhood sexual abuse (CSA) is a specific risk factor for pedophilia as opposed to other types of addictive disorders by comparing the childhood sexual histories of 48 pedophilic sex offenders, 25 subjects with opiate addiction in remission, and 61 healthy controls. CSA was assessed with The Sexual History Questionnaire and the Child Trauma Questionnaire (CTQ). Compared with both opiate addicted subjects and healthy controls, subjects with pedophilia were more likely to report experiencing adult sexual advances when they were children and a first sexual contact by age 13 with a partner at least 5 years older. Although both subjects with pedophilia and those with opiate addiction first had sex at a younger age than healthy controls, opiate addicted subjects, compared with healthy controls, reported neither increased reception of sexual advances as children nor increased rates of first sexual contact before age 13 with a partner at least 5 years older. Further, subjects with pedophilia but not those with opiate addiction scored significantly higher than healthy controls on the CTQ. Sexual abuse in childhood may be a specific risk factor for sexual addictions such as pedophilia but may not be a specific risk factor for chemical addictions.

  15. [The Nature and Issues of Drug Addiction Treatment under Constraint].

    Science.gov (United States)

    Quirion, Bastien

    This article is exploring different forms of constraint that are exerted in the field of drug addiction treatment. The objective of this article is to establish benchmarks and to stimulate reflection about the ethical and clinical implications of those constraints in the field of drug addiction treatment. This article is presenting a critical review of different forms of constraint that can be exerted in Canada in regard to the treatment of drug addiction. In the first section of the article, a definition of therapeutic intervention is proposed, that includes the dimension of power, which justifies the importance of considering the coercive aspects of treatment. The second section, which represents the core section of the paper, is devoted to the presentation of different levels of constraint that can be distinguished in regard to drug addicts who are under treatment. Three levels of constraint are exposed: judicial constraint, institutional constraint and relational constraint. The coercive aspect of treatment can then be recognized as a combination of all tree levels of constraint. Judicial constraint refers to any form of constraint in which the court or the judge is imposing or recommending treatment. This particular level of constraint can take different forms, such as therapeutic remands, conditions of a probation order, conditions of a conditional sentence of imprisonment, and coercive treatment such as the ones provided through drug courts. Institutional constraint refers to any form of constraint exerted within any institutional setting, such as correctional facilities and programs offered in community. Correctional facilities being limited by their own specific mission, it might have a major impact on the way the objectives of treatment are defined. Those limitations can then be considered as a form of constraint, in which drug users don't have much space to express their personal needs. Finally, relational constraint refers to any form of constraint in

    Glutamatergic excitatory transmission is implicated in physiological and pathological conditions like learning, memory, neuronal plasticity and emotions, while glutamatergic abnormalities are reported in numerous neurological and psychiatric disorders, including neurodegenerative diseases, epilepsy, stroke, traumatic brain injury, depression, anxiety, schizophrenia and pain. Also, several lines of evidence have accumulated indicating a pivotal role for glutamatergic neurotransmission in mediating addictive behaviors. Among the proteins regulating glutamatergic transmission, the metabotropic glutamate receptors (mGluR) are being developed as pharmacological targets for treating many neuropsychiatric disorders, including drug addiction. In this review we describe the molecular structure of mGluRs and their distribution, physiology and pharmacology in the central nervous system, as well as their use as targets in preclinical studies of drug addiction.

    2016-05-01

    Full Text Available Employees who abuse Internet privileges have become a major concern among today's employers. Employees misuse Internet at the workplace due to the overcrowded schedule, pressures at work, etc. Internet for private purposes is also used as a release or escape from work, escape from the reality of the workplace or due to poor organizational climate; it can be used as an efficient use of time at work but it can also be excessively used when the employees are not monitored. The survey results show that there is a correlation between Internet addiction and misuse of the Internet in the workplace. Electronic monitoring has a strong impact on the abuse of the Internet. More electronic monitoring will decrease the abuse of the internet services in the workplace and vice versa. Organizational climate, relations in the working organization, the Internet policy and demographic factors do not affect the abuse of Internet services in the workplace.

    Science.gov (United States)

    Anker, Justin J; Carroll, Marilyn E

    2011-01-01

    Human and animal research indicates the presence of sex differences in drug abuse. These data suggest that females, compared to males, are more vulnerable to key phases of the addiction process that mark transitions in drug use such as initiation, drug bingeing, and relapse. Recent data indicate that the female gonadal hormone estrogen may facilitate drug abuse in women. For example, phases of the menstrual cycle when estrogen levels are high are associated with enhanced positive subjective measures following cocaine and amphetamine administration in women. Furthermore, in animal research, the administration of estrogen increases drug taking and facilitates the acquisition, escalation, and reinstatement of cocaine-seeking behavior. Neurobiological data suggest that estrogen may facilitate drug taking by interacting with reward- and stress-related systems. This chapter discusses sex differences in and hormonal effects on drug-seeking behaviors in animal models of drug abuse. The neurobiological basis of these differences and effects are also discussed.

    Drug abuse is both a personal and a public issue, raising questions about individual rights and the boundaries of law, as well as about national sovereignty and international control. Ethical issues that arise under these headings may be related to certain broad ethical positions. The implications of adopting utilitarian assumptions may be contrasted with basing ethics on a theory of individual rights, closely related to a theory of human nature. Neither position justifies a libertarian presumption against control, for, first, an individual decision to expose one's mind and personality to the control of drugs cannot be ethically justified and, second, there are no ethical reasons, nor any compelling arguments from social and political theory, for decriminalizing non-medical drug use.

    Addiction is a chronic and relapsing psychiatric disorder that is thought to occur in vulnerable individuals. Synaptic plasticity evoked by drugs of abuse in the so-called neuronal circuits of reward has been proposed to underlie behavioral adaptations that characterize addiction. By increasing dopamine in the striatum, addictive drugs alter the balance of dopamine and glutamate signals converging onto striatal medium-sized spiny neurons (MSNs) and activate intracellular events involved in long-term behavioral alterations. Our laboratory contributed to the identification of salient molecular changes induced by administration of addictive drugs to rodents. We pioneered the observation that a common feature of addictive drugs is to activate, by a double tyrosine/threonine phosphorylation, the extracellular signal-regulated kinases 1 and 2 (ERK1/2) in the striatum, which control a plethora of substrates, some of them being critically involved in cocaine-mediated molecular and behavioral adaptations. Herein, we review how the interplay between dopamine and glutamate signaling controls cocaine-induced ERK1/2 activation in MSNs. We emphasize the key role of N-methyl-D-aspartate receptor potentiation by D1 receptor to trigger ERK1/2 activation and its subsequent nuclear translocation where it modulates both epigenetic and genetic processes engaged by cocaine. We discuss how cocaine-induced long-term synaptic and structural plasticity of MSNs, as well as behavioral adaptations, are influenced by ERK1/2-controlled targets. We conclude that a better knowledge of molecular mechanisms underlying ERK1/2 activation by drugs of abuse and/or its role in long-term neuronal plasticity in the striatum may provide a new route for therapeutic treatment in addiction.

  7. Intracranial self-stimulation to evaluate abuse potential of drugs.

    Science.gov (United States)

    Negus, S Stevens; Miller, Laurence L

    2014-07-01

    Intracranial self-stimulation (ICSS) is a behavioral procedure in which operant responding is maintained by pulses of electrical brain stimulation. In research to study abuse-related drug effects, ICSS relies on electrode placements that target the medial forebrain bundle at the level of the lateral hypothalamus, and experimental sessions manipulate frequency or amplitude of stimulation to engender a wide range of baseline response rates or response probabilities. Under these conditions, drug-induced increases in low rates/probabilities of responding maintained by low frequencies/amplitudes of stimulation are interpreted as an abuse-related effect. Conversely, drug-induced decreases in high rates/probabilities of responding maintained by high frequencies/amplitudes of stimulation can be interpreted as an abuse-limiting effect. Overall abuse potential can be inferred from the relative expression of abuse-related and abuse-limiting effects. The sensitivity and selectivity of ICSS to detect abuse potential of many classes of abused drugs is similar to the sensitivity and selectivity of drug self-administration procedures. Moreover, similar to progressive-ratio drug self-administration procedures, ICSS data can be used to rank the relative abuse potential of different drugs. Strengths of ICSS in comparison with drug self-administration include 1) potential for simultaneous evaluation of both abuse-related and abuse-limiting effects, 2) flexibility for use with various routes of drug administration or drug vehicles, 3) utility for studies in drug-naive subjects as well as in subjects with controlled levels of prior drug exposure, and 4) utility for studies of drug time course. Taken together, these considerations suggest that ICSS can make significant contributions to the practice of abuse potential testing.

    Traub, S J; Levine, M D

    2017-01-01

    Many substances can affect the central nervous system, and may cause patients to become critically ill. Acute central neurotoxicologic syndromes associated with drugs of abuse are usually caused by an overdose of sedative-hypnotic agents (including alcohol) or opioids, withdrawal from sedative-hypnotic agents, or an overdose of anticholinergic or sympathomimetic agents. Clinical findings are often syndromic, making physical examination the most important diagnostic tool in the approach to the patient with an unknown ingestion. Treatment focusses on supportive care as the most important intervention for all such patients, augmented by antidotal therapy when appropriate. © 2017 Elsevier B.V. All rights reserved.

    Opioid use in chronic pain treatment is complex, as patients may derive both benefit and harm. Identification of individuals currently using opioids in a problematic way is important given the substantial recent increases in prescription rates and consequent increases in morbidity and mortality. The present review provides updated and expanded information regarding rates of problematic opioid use in chronic pain. Because previous reviews have indicated substantial variability in this literature, several steps were taken to enhance precision and utility. First, problematic use was coded using explicitly defined terms, referring to different patterns of use (ie, misuse, abuse, and addiction). Second, average prevalence rates were calculated and weighted by sample size and study quality. Third, the influence of differences in study methodology was examined. In total, data from 38 studies were included. Rates of problematic use were quite broad, ranging from addiction averaged between 8% and 12% (range, 95% CI: 3%-17%). Abuse was reported in only a single study. Only 1 difference emerged when study methods were examined, where rates of addiction were lower in studies that identified prevalence assessment as a primary, rather than secondary, objective. Although significant variability remains in this literature, this review provides guidance regarding possible average rates of opioid misuse and addiction and also highlights areas in need of further clarification.

  13. The meaning of suffering in drug addiction and recovery from the perspective of existentialism, Buddhism and the 12-Step program.

    The aim of the current article was to examine the meaning of suffering in drug addiction and in the recovery process. Negative emotions may cause primary suffering that can drive an individual toward substance abuse. At the same time, drugs only provide temporary relief, and over time, the pathological effects of the addiction worsen causing secondary suffering, which is a motivation for treatment. The 12-Step program offers a practical way to cope with suffering through a process of surrender. The act of surrender sets in motion a conversion experience, which involves a self-change including reorganization of one's identity and meaning in life. This article is another step toward understanding one of the several factors that contribute to the addict's motivation for treatment. This knowledge may be helpful for tailoring treatment that addresses suffering as a factor that initiates treatment motivation and, in turn, treatment success.

    2016-07-01

    In the 1970s, Turkey ceased to be a significant producer state of illicit drugs, but it continued to serve as a key route for the trade of drugs between East and West. Over the past decade, however, authorities identified two concerns beyond its continued transit state status. These reported problems entail both new modes of production and a rising incidence of drug abuse within the nation-state - particularly among its youth. Amid these developments, new law enforcement institutions emerged and acquired European sponsorship, leading to the establishment of TUBİM (the Turkish Monitoring Center for Drugs and Drug Addiction). Coordinating with and reporting to the European Union agency EMCDDA (the European Monitoring Center for Drugs and Drug Addiction), TUBİM's primary assigned duties entail the collection and analysis of data on drug abuse, trafficking, and prevention, the geographic identification of sites of concern (e.g. consumption, drug-related crimes, and peoples undergoing treatment), and the production of annual national reports. In this article, we examine the geopolitical origins of TUBİM as Turkey's central apparatus for confronting drug problems and its role as a vehicle for policy development, interpretation, and enforcement. In doing so, we emphasize the political and spatial dimensions inherent to the country's institutional and policy-driven approaches to contend with drug-related problems, and we assess how this line of attack reveals particular ambiguities in mission when evaluated from scales at world regional, national, and local levels. In sum, we assess how Turkey's new institutional and legislative landscapes condition the state's engagements with drug use, matters of user's health, and policy implementation at local scales and amid ongoing political developments.

    Addiction biology has focused on the mechanisms of the positive and negative reinforcing actions of addictive drugs but neglected potential benefits. Two new studies provide the first insights into a neurobiology of psychoactive drug instrumentalization. This may help us design better models for addiction neuroscience and opens a new dimension for the development of personalized pharmacotherapy of drug addiction. Copyright © 2017 Elsevier Ltd.

  20. The dopamine motive system: implications for drug and food addiction.

    Science.gov (United States)

    Volkow, Nora D; Wise, Roy A; Baler, Ruben

    2017-11-16

    Behaviours such as eating, copulating, defending oneself or taking addictive drugs begin with a motivation to initiate the behaviour. Both this motivational drive and the behaviours that follow are influenced by past and present experience with the reinforcing stimuli (such as drugs or energy-rich foods) that increase the likelihood and/or strength of the behavioural response (such as drug taking or overeating). At a cellular and circuit level, motivational drive is dependent on the concentration of extrasynaptic dopamine present in specific brain areas such as the striatum. Cues that predict a reinforcing stimulus also modulate extrasynaptic dopamine concentrations, energizing motivation. Repeated administration of the reinforcer (drugs, energy-rich foods) generates conditioned associations between the reinforcer and the predicting cues, which is accompanied by downregulated dopaminergic response to other incentives and downregulated capacity for top-down self-regulation, facilitating the emergence of impulsive and compulsive responses to food or drug cues. Thus, dopamine contributes to addiction and obesity through its differentiated roles in reinforcement, motivation and self-regulation, referred to here as the 'dopamine motive system', which, if compromised, can result in increased, habitual and inflexible responding. Thus, interventions to rebalance the dopamine motive system might have therapeutic potential for obesity and addiction.

    Drugs and food exert their reinforcing effects in part by increasing dopamine (DA) in limbic regions, which has generated interest in understanding how drug abuse/addiction relates to obesity. Here, we integrate findings from positron emission tomography imaging studies on DA's role in drug abuse/addiction and in obesity and propose a common model for these two conditions. Both in abuse/addiction and in obesity, there is an enhanced value of one type of reinforcer (drugs and food, respectivel...

  2. Rapid Assessment of Drugs of Abuse.

    Wiencek, Joesph R; Colby, Jennifer M; Nichols, James H

    Laboratory testing for drugs of abuse has become standard practice in many settings both forensic and clinical. Urine is the predominant specimen, but other specimens are possible including hair, nails, sweat, and oral fluid. Point-of-care test kits provide for rapid analysis at the site where specimens are collected allowing for immediate action on the results. POCT is based on immunochromatography where the drug in the patient's sample competes with drug and antibody conjugates in the test to develop or block the development of a colored line. Most POCTs are visually interpreted in a few minutes. The potential for false positives is possible due to drug cross-reactivity with the antibodies in the test. False negatives are also possible due to dilution of the sample and the potential for adulteration or sample substitution by the patient. POCT shows more variability than central laboratory testing because of the variety of operators involved in the testing process, but POCT has good agreement for most tests with mass spectrometry provided comparable cutoffs and cross-reactivity of drugs/metabolites are considered. Validation of the test performance with the intended operators will identify potential interferences and operational issues before implementing the test in routine practice. POCT offers faster turnaround of test results provided the limitations and challenges of the test are considered. © 2017 Elsevier Inc. All rights reserved.

    In the past two decades a trickle of manuscripts examining the non-neuronal central nervous system immune consequences of the drugs of abuse has now swollen to a significant body of work. Initially, these studies reported associative evidence of central nervous system proinflammation resulting from exposure to the drugs of abuse demonstrating key implications for neurotoxicity and disease progression associated with, for example, HIV infection. However, more recently this drug-induced activation of central immune signaling is now understood to contribute substantially to the pharmacodynamic actions of the drugs of abuse, by enhancing the engagement of classical mesolimbic dopamine reward pathways and withdrawal centers. This review will highlight the key in vivo animal, human, biological and molecular evidence of these central immune signaling actions of opioids, alcohol, cocaine, methamphetamine, and 3,4-methylenedioxymethamphetamine (MDMA). Excitingly, this new appreciation of central immune signaling activity of drugs of abuse provides novel therapeutic interventions and opportunities to identify 'at risk' individuals through the use of immunogenetics. Discussion will also cover the evidence of modulation of this signaling by existing clinical and pre-clinical drug candidates, and novel pharmacological targets. Finally, following examination of the breadth of central immune signaling actions of the drugs of abuse highlighted here, the current known common immune signaling components will be outlined and their impact on established addiction neurocircuitry discussed, thereby synthesizing a common neuroimmune hypothesis of addiction.

    Full Text Available Background: About 8 percent of Iranian adult population are illicit drug abusers. Affected persons grow more each day. Ominous consequences such as divorce, prostitution, murder and other crimes and infectious diseases such as AIDS and hepatitis take place following drug abuse, as well as a loss equall to 29% of national income for our country. Traditional treatment methods wasted too much time and cost. professional inpatient clinics are not adequate for admission of all care seekers. Rapid detoxification methods are supposed to be better alternatives. Materials and Methods: 140 male drug abusers in two matched groups were assessed from March to September, 2005. They used heroin or opium. Both groups were scheduled for detoxification and were closely observed for 3 months thereafter. First group received Clonidine, Benzodiazepine and Naltrexone besides symptom relieving modalities in first 4 days of treatment. Naltrexone was continued in maintenance dose for one month. Second group received Methadone for one month. Results: Clients age was between 18 to 73 years, with mean age 34 years old. Their intelligence quotients were above the lower limit of normal range. There was no significant difference according to these parameters between two groups. Success rate in rapid detoxification group was 55 % and in Methadone group was 50 %. Relapse in rapid detoxification method occurred less frequent and slower (45 % vs. 50%. In Naltrexone group, better success rate was due to less duration of drug abuse and heroin dependency. In Methadone group, therapy had better results in patients with longer drug abuse history and opium addiction. There was no significant difference between success rate and either drug kind or job, marital status or education level. The most serious adverse effect in both groups was hypotension (10% in Naltrexone and 5 % in Methadone groups.

  6. Stigma, discrimination, treatment effectiveness, and policy: public views about drug addiction and mental illness.

    Public attitudes about drug addiction and mental illness were compared. A Web-based national survey (N=709) was conducted to compare attitudes about stigma, discrimination, treatment effectiveness, and policy support in regard to drug addiction and mental illness. Respondents held significantly more negative views toward persons with drug addiction. More respondents were unwilling to have a person with drug addiction marry into their family or work closely with them. Respondents were more willing to accept discriminatory practices against persons with drug addiction, more skeptical about the effectiveness of treatments, and more likely to oppose policies aimed at helping them. Drug addiction is often treated as a subcategory of mental illness, and insurance plans group them together under the rubric of "behavioral health." Given starkly different public views about drug addiction and mental illness, advocates may need to adopt differing approaches to reducing stigma and advancing public policy.

    Background and aims Pathological gambling is associated with comorbid disorders, such as anxiety, depression, and drug and alcohol abuse. Difficulties of emotion regulation may be one of the factors related to the presence of addictive disorders, along with comorbid symptomatology in pathological gamblers. Therefore, the aim of this study was to evaluate the difficulties of emotion regulation, drug and alcohol abuse, and anxious and depressive symptomatology in pathological gamblers, and the mediating role of difficulties of emotion regulation between anxiety and pathological gambling. Methods The study sample included 167 male pathological gamblers (mean age = 39.29 years) and 107 non-gamblers (mean age = 33.43 years). Pathological gambling (SOGS), difficulties of emotion regulation (DERS), drug and alcohol abuse (MUTICAGE CAD-4), and anxious and depressive symptomatology (SA-45) were measured. Student's t, Pearson's r, stepwise multiple linear regression and multiple mediation analyses were conducted. The study was approved by an Investigational Review Board. Results Relative to non-gamblers, pathological gamblers exhibited greater difficulties of emotion regulation, as well as more anxiety, depression, and drug abuse. Moreover, pathological gambling correlated with emotion regulation difficulties, anxiety, depression, and drug abuse. Besides, emotion regulation difficulties correlated with and predicted pathological gambling, drug and alcohol abuse, and anxious and depressive symptomatology. Finally, emotion regulation difficulties mediated the relationship between anxiety and pathological gambling controlling the effect of age, both when controlling and not controlling for the effect of other abuses. Discussion and conclusions These results suggest that difficulties of emotion regulation may provide new keys to understanding and treating pathological gambling and comorbid disorders.

  8. Redox-based epigenetic status in drug addiction: a potential contributor to gene priming and a mechanistic rationale for metabolic intervention.

    Trivedi, Malav S; Deth, Richard

    2014-01-01

    Alcohol and other drugs of abuse, including psychostimulants and opioids, can induce epigenetic changes: a contributing factor for drug addiction, tolerance, and associated withdrawal symptoms. DNA methylation is a major epigenetic mechanism and it is one of more than 200 methylation reactions supported by methyl donor S-adenosylmethionine (SAM). Levels of SAM are controlled by cellular redox status via the folate and vitamin B12-dependent enzyme methionine synthase (MS). For example, under oxidative conditions MS is inhibited, diverting its substrate homocysteine (HCY) to the trans sulfuration pathway. Alcohol, dopamine, and morphine, can alter intracellular levels of glutathione (GSH)-based cellular redox status, subsequently affecting SAM levels and DNA methylation status. Here, existing evidence is presented in a coherent manner to propose a novel hypothesis implicating the involvement of redox-based epigenetic changes in drug addiction. Further, we discuss how a "gene priming" phenomenon can contribute to the maintenance of redox and methylation status homeostasis under various stimuli including drugs of abuse. Additionally, a new mechanistic rationale for the use of metabolic interventions/redox-replenishers as symptomatic treatment of alcohol and other drug addiction and associated withdrawal symptoms is also provided. Hence, the current review article strengthens the hypothesis that neuronal metabolism has a critical bidirectional coupling with epigenetic changes in drug addiction exemplified by the link between redox-based metabolic changes and resultant epigenetic consequences under the effect of drugs of abuse.

  9. NIDA-Drug Addiction Treatment Outcome Study (DATOS) Relapse as a Function of Spirituality/Religiosity.

    The connection between religion/spirituality and deviance, like substance abuse, was first made by Durkheim who defined socially expected behaviors as norms. He explained that deviance is due in large part to their absence (called anomie), and concluded that spirituality lowers deviance by preserving norms and social bonds. Impairments in brain reward circuitry, as observed in Reward Deficiency Syndrome (RDS), may also result in deviance and as such we wondered if stronger belief in spirituality practice and religious belief could lower relapse from drugs of abuse. The NIDA Drug Addiction Treatment Outcome Study data set was used to examine post hoc relapse rates among 2,947 clients who were interviewed at 12 months after intake broken down by five spirituality measures. Our main findings strongly indicate, that those with low spirituality have higher relapse rates and those with high spirituality have higher remission rates with crack use being the sole exception. We found significant differences in terms of cocaine, heroin, alcohol, and marijuana relapse as a function of strength of religious beliefs (x 2 = 15.18, p = 0.028; logistic regression = 10.65, p = 0.006); frequency of attending religious services (x 2 = 40.78, p Durkheim's social bond theory. Stronger spiritual/religious beliefs and practices are directly associated with remission from abused drugs except crack. Much like the value of having a sponsor, for clients who abuse drugs, regular spiritual practice, particularly weekly attendance at the religious services of their choice is associated with significantly higher remission. These results demonstrate the clinically significant role of spirituality and the social bonds it creates in drug treatment programs.

    Different immunotherapeutic approaches are in the pipeline for the treatment of drug dependence. "Drug vaccines" aim to induce the immune system to produce antibodies that bind to drugs and prevent them from inducing rewarding effects in the brain. Drugs of abuse currently being tested using these new approaches are opioids, nicotine, cocaine, and methamphetamine. In human clinical trials, "cocaine and nicotine vaccines" have been shown to induce sufficient antibody levels while producing few side effects. Studies in humans, determining how these vaccines interact in combination with their target drug, are underway. However, although vaccines can become a reasonable treatment option for drugs of abuse, there are several disadvantages that must be considered. These include i) great individual variability in the formation of antibodies, ii) the lack of protection against a structurally dissimilar drug that produces the same effects as the drug of choice, and iii) the lack of an effect on the drug desire that may predispose an addict to relapse. In addition, a comprehensive overview of several crucial ethical issues has not yet been widely discussed in order to have not only a biological approach to immunotherapy of addiction. Overall, immunotherapy offers a range of possible treatment options: the pharmacological treatment of addiction, the treatment of overdoses, the prevention of toxicity to the brain or the heart, and the protection of the fetus during pregnancy. So far, the results obtained from a small-scale experiment using vaccines against cocaine and nicotine suggest that a number of important technical challenges still need to be overcome before such vaccines can be approved for clinical use.

    Coffee, tea, chocolate and caffeinated drinks are the main sources of caffeine, which is consumed in almost all ages and socioeconomic levels. Caffeine acts as a non-selective adenosine receptor antagonist in the central nervous system. Its main effects are as psychostimulant, acting in addition on the respiratory, muscular and cardiovascular systems. Basically, caffeine is metabolized by the hepatic cytochrome P-450 1A2 enzymes (CYP1A2). Several drugs can interact with its metabolism. The observed interindividual differences of its effects can be explained by variations in its metabolism. The main therapeutic use of caffeine is bronchodilator in respiratory diseases. Other possible uses are under investigation. Acute or chronic consumption of caffeine can induce several adverse effects, including intoxication that can be lethal. Finally, caffeine can be considered a drug of abuse. It has positive reinforcing actions, produces tolerance, and a withdrawal syndrome after stopping its consumption. Caffeine can cause different mental disorders such as dependence, which is not included in the DSM-IV-R, withdrawal syndrome and intoxication. Depending on its use, caffeine can be considered a nutrient, a drug or a drug of abuse.

    The aim of the present study was to determine the prevalence and correlates of dissociative disorders among patients with drug dependency. The Dissociative Experiences Scale (DES) was used to screen 104 consecutive patients at an addiction treatment center. Thirty-seven patients who had scores >or=30 were compared with 21 patients who scored suicide attempt and/or childhood emotional abuse was significant predictors of a dissociative disorder. The majority (59.3%) of dissociative drug users reported that dissociative experiences had existed prior to substance use. More patients in the dissociative disorder than in the non-dissociative group stopped their treatment prematurely. A considerable proportion of drug users have a dissociative disorder, which may also interfere with treatment process. The relatively young age of this subgroup of patients and frequent reports of childhood emotional abuse underline potential preventive benefits of early intervention among adolescents with developmental trauma history and dissociative psychopathology.
