    Exposure to cigarette smoke among smokers is highly variable. This variability has been attributed to differences in smoking behavior as measured by smoking topography, as well as other behavioral and subjective aspects of smoking. The objective of this study was to determine the factors affecting smoke exposure as estimated by biomarkers of exposure to nicotine and carbon monoxide (CO). In a multi-center cross-sectional study of 3585 adult smokers and 1077 adult nonsmokers, exposure to nicotine and CO was estimated by 24h urinary excretion of nicotine and five of its metabolites and by blood carboxyhemoglobin, respectively. Number of cigarettes smoked per day (CPD) was determined from cigarette butts returned. Puffing parameters were determined through a CreSS® micro device and a 182-item adult smoker questionnaire (ASQ) was administered. The relationship between exposure and demographic factors, smoking machine measured tar yield and CPD was examined in a statistical model (Model A). Topography parameters were added to this model (Model B) which was further expanded (Model C) by adding selected questions from the ASQ identified by a data reduction process. In all the models, CPD was the most important and highest ranking factor determining daily exposure. Other statistically significant factors were number of years smoked, questions related to morning smoking, topography and tar yield categories. In conclusion, the models investigated in this analysis, explain about 30-40% of variability in exposure to nicotine and CO.

    The novelty of e-cigarettes and ambiguity about their effects may foster informal sharing of information, such as through social interactions. We aimed to describe smokers’ social interactions about e-cigarettes and their recommendations that others use e-cigarettes. Data were collected from 2149 adult smokers in North Carolina and California who participated in a study of the impact of pictorial cigarette pack warnings. In the previous month, almost half of participants (45%) reported talking to at least one person about e-cigarettes and nearly a third of participants (27%) recommended e-cigarettes to someone else. Smokers recommended e-cigarettes to cut back on smoking (57%), to quit smoking (48%), for health reasons (36%), and for fun (27%). In adjusted analyses, more frequent e-cigarette use, positive views about typical e-cigarette users, and attempting to quit smoking in the past month were associated with recommending e-cigarettes for health reasons (all p < 0.05). Social interactions appear to be a popular method of information-sharing about e-cigarettes among smokers. Health communication campaigns may help to fill in the gaps of smokers’ understanding of e-cigarettes and their long-term effects. PMID:27527199

    Full Text Available This study investigates 1 the relationship between menthol cigarette smoking and obesity and 2 the association of body mass index with the nicotine metabolite ratio among menthol and non-menthol daily smokers aged 18–35 (n = 175. A brief survey on smoking and measures of height and weight, carbon monoxide, and saliva samples were collected from participants from May to December 2013 in Honolulu, Hawaii. Multiple regression was used to estimate differences in body mass index among menthol and non-menthol smokers and the association of menthol smoking with obesity. We calculated the log of the nicotine metabolite ratio to examine differences in the nicotine metabolite ratio among normal, overweight, and obese smokers. Sixty-eight percent of smokers used menthol cigarettes. Results showed that 62% of normal, 54% of overweight, and 91% of obese smokers used menthol cigarettes (p = .000. The mean body mass index was significantly higher among menthol compared with non-menthol smokers (29.4 versus 24.5, p = .000. After controlling for gender, marital status, educational attainment, employment status, and race/ethnicity, menthol smokers were more than 3 times as likely as non-menthol smokers to be obese (p = .04. The nicotine metabolite ratio was significantly lower for overweight menthol smokers compared with non-menthol smokers (.16 versus .26, p = .02 in the unadjusted model, but was not significant after adjusting for the covariates. Consistent with prior studies, our data show that menthol smokers are more likely to be obese compared with non-menthol smokers. Future studies are needed to determine how flavored tobacco products influence obesity among smokers.

    Small cigar smoking among young adult cigarette smokers may be attributed to their exposure to its advertisements and promotions. We examined the association between exposure to a celebrity music artist's endorsement of a specific brand of small cigars and young adult cigarette smokers' susceptibility to smoking that brand. Venue-based sampling procedures were used to select and survey a random sample of 121 young adult cigarette smokers, aged 18-35. Fourteen percent reported exposure to the artist's endorsement of the small cigar and 45.4% reported an intention to smoke the product in the future. The odds of small cigar smoking susceptibility increased threefold for those who reported exposure to the endorsement compared to those not exposed (OR = 3.64, 95% CI 1.06 to 12.54). Past 30-day small cigar use (OR = 3.30, 95% CI 1.24 to 8.74) and past 30-day cigar use (OR = 5.08, 95% CI 1.23, 21.08) were also associated with susceptibility to smoke a small cigar. An association between young adult cigarette smokers' exposure to the music artist's small cigar endorsement and their susceptibility to smoke small cigars was found. This association underscores the importance of monitoring small cigar promotions geared toward young people and their impact on small cigar product smoking. PMID:24371444

    Rationale. To date no state-of-the-art clinical study has been conducted to address the question as to whether switching to lower tar cigarettes reduces exposure to smoke constituents in humans. Methods. Randomized, controlled, forced switching study in 225 adult smokers of full flavor Marlboro (MFF) cigarettes for 8 days with a 24-week follow-up. Subjects smoked MFF (a 15-mg Federal Trade Commission (FTC) tar cigarette) at baseline and were randomized to smoke 11-mg Marlboro Lights (ML) or 6-mg Marlboro Ultra Lights (MUL) cigarettes. Biomarkers of exposure to nicotine, 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), pyrene, CO, benzene, acrolein, and mutagenic substances were measured. Results. In the short-term phase, switching from MFF to ML showed statistically significant decreases in nicotine exposure (-13%) and non-significant increases in CO exposure (+6%), while switching from MFF to MUL showed statistically significant decreases in nicotine (-27%) and CO (-13%) exposure. Both nicotine and CO biomarkers trended similarly in the 24-week follow-up as in the short-term phase. The other biomarkers of cigarette smoke constituents followed the same trend as nicotine at the end of the 24-week follow-up. Conclusions. Switching smokers to lower FTC tar yield cigarettes, on average, reduces nicotine and other biomarkers considered surrogates of tar exposure. PMID:18565634

    Full Text Available Introduction: Pulmonary function is compromised in most smokers. Yet it is unknown whether exercise training improves pulmonary function and aerobic capacity in cigarette and hookah smokers and whether these smokers respond in a similar way as do non-smokers. Aim: To evaluate the effects of an interval exercise training program on pulmonary function and aerobic capacity in cigarette and hookah smokers. Methods: Twelve cigarette smokers, 10 hookah smokers, and 11 non-smokers participated in our exercise program. All subjects performed 30 min of interval exercise (2 min of work followed by 1 min of rest three times a week for 12 weeks at an intensity estimated at 70% of the subject's maximum aerobic capacity (VO2max. Pulmonary function was measured using spirometry, and maximum aerobic capacity was assessed by maximal exercise testing on a treadmill before the beginning and at the end of the exercise training program. Results: As expected, prior to the exercise intervention, the cigarette and hookah smokers had significantly lower pulmonary function than the non-smokers. The 12-week exercise training program did not significantly affect lung function as assessed by spirometry in the non-smoker group. However, it significantly increased both forced expiratory volume in 1 second and peak expiratory flow (PEF in the cigarette smoker group, and PEF in the hookah smoker group. Our training program had its most notable impact on the cardiopulmonary system of smokers. In the non-smoker and cigarette smoker groups, the training program significantly improved VO2max (4.4 and 4.7%, respectively, v VO2max (6.7 and 5.6%, respectively, and the recovery index (7.9 and 10.5%, respectively. Conclusions: After 12 weeks of interval training program, the increase of VO2max and the decrease of recovery index and resting heart rate in the smoking subjects indicated better exercise tolerance. Although the intermittent training program altered pulmonary function only

    Full Text Available Abstract Background This article describes the data mining analysis of a clinical exposure study of 3585 adult smokers and 1077 nonsmokers. The analysis focused on developing models for four biomarkers of potential harm (BOPH: white blood cell count (WBC, 24 h urine 8-epi-prostaglandin F2α (EPI8, 24 h urine 11-dehydro-thromboxane B2 (DEH11, and high-density lipoprotein cholesterol (HDL. Methods Random Forest was used for initial variable selection and Multivariate Adaptive Regression Spline was used for developing the final statistical models Results The analysis resulted in the generation of models that predict each of the BOPH as function of selected variables from the smokers and nonsmokers. The statistically significant variables in the models were: platelet count, hemoglobin, C-reactive protein, triglycerides, race and biomarkers of exposure to cigarette smoke for WBC (R-squared = 0.29; creatinine clearance, liver enzymes, weight, vitamin use and biomarkers of exposure for EPI8 (R-squared = 0.41; creatinine clearance, urine creatinine excretion, liver enzymes, use of Non-steroidal antiinflammatory drugs, vitamins and biomarkers of exposure for DEH11 (R-squared = 0.29; and triglycerides, weight, age, sex, alcohol consumption and biomarkers of exposure for HDL (R-squared = 0.39. Conclusions Levels of WBC, EPI8, DEH11 and HDL were statistically associated with biomarkers of exposure to cigarette smoking and demographics and life style factors. All of the predictors togather explain 29%-41% of the variability in the BOPH.

    Rationale Cigarette smoking has been linked to real-world risky behavior, but this association has been based largely on retrospective self-reports. Limitations of self-report data can be avoided by using laboratory, performance-based measures, such as the Balloon Analogue Risk Task (BART; Lejuez et al., J Exp Psychol Appl 8:75–84, 2002). Initial studies have suggested that smokers display greater risk-taking on this task than nonsmokers, but these studies did not account for drug abuse and p...

    Cigarette butts are consistently the most collected items in litter clean-up efforts, which are a costly burden to local economies. In addition, tobacco waste may be detrimental to our natural environment. The tobacco industry has conducted or funded numerous studies on smokers' littering knowledge and behavior, however, non-industry sponsored research is rare. We sought to examine whether demographics and smokers' knowledge and beliefs toward cigarette waste as litter predicts littering behavior. Smokers aged 18 and older (n = 1,000) were interviewed about their knowledge and beliefs towards cigarette waste as litter. Respondents were members of the Research Now panel, an online panel of over three million respondents in the United States. Multivariate logistic regressions were conducted to determine factors significantly predictive of ever having littered cigarette butts or having littered cigarette butts within the past month (p-value cigarette butts at least once in their life, by disposing of them on the ground or throwing them out of a car window. Over half (55.7%) reported disposing of cigarette butts on the ground, in a sewer/gutter, or down a drain in the past month. Those who did not consider cigarette butts to be litter were over three and half times as likely to report having ever littered cigarette butts (OR = 3.68, 95%CI = 2.04, 6.66) and four times as likely to have littered cigarette butts in the past month (OR = 4.00, 95%CI = 2.53, 6.32). Males were significantly more likely to have littered cigarette butts in the past month compared to females (OR = 1.49, 95%CI = 1.14, 1.94). Holding the belief that cigarette butts are not litter was the only belief in this study that predicted ever or past-month littering of cigarette waste. Messages in anti-cigarette-litter campaigns should emphasize that cigarette butts are not just litter but are toxic waste and are harmful when disposed of improperly.

    Cigarette warning labels are important sources of risk information, but warning research for other tobacco products is limited. This study aimed to gauge perceptions about warnings that may be used for e-cigarettes. We conducted six small focus groups in late 2014/early 2015 with adult current e-cigarette users and cigarette-only smokers. Participants rated and discussed their perceptions of six e-cigarette warning statements, and warnings in two existing Vuse and MarkTen e-cigarette ads. Participants were open to e-cigarette warnings and provided the strongest reactions to statements warning that e-liquid/e-vapor or e-cigarettes can be poisonous, contain toxins, or are "not a safe alternative to smoking". However, many also noted that these statements were exaggerated, potentially misleading, and could scare smokers away from reducing their harm by switching to e-cigarettes. Opinions on the Food and Drug Administration's proposed nicotine addiction warning and warnings that e-cigarettes had not been approved for smoking cessation or had unknown health effects were mixed. Participants perceived MarkTen's advertisement warning to be stronger and more noticeable than Vuse's. Care should be taken in developing e-cigarette warnings given their relative recentness and potential for harm reduction compared to other tobacco products. Additional research, including with varied audiences, would be instructive. PMID:27376310

    Full Text Available This cross-sectional study examined the differences in barriers to cessation and reasons for quitting smoking among dual smokers of cigarettes and waterpipe tobacco, exclusive cigarette smokers and exclusive waterpipe smokers. Participants were Arab American adults residing in Richmond, Virginia, who were recruited from Middle Eastern grocery stores, restaurants/lounges and faith and charity organizations. The study yielded several key findings: (1 Exclusive cigarette and waterpipe smokers had similar mean barriers to quitting and were more concerned about their health than dual smokers. (F(2, 150 = 5.594, p = 0.0045. This implies that barriers to smoking and health concerns could be a function of the individual who smokes rather than the modality of smoking itself. (2 Exclusive cigarette or waterpipe smokers and dual smokers may have different reasons for quitting, since they have different reasons for smoking. The proportion of smokers who endorsed smoking as a messy habit as the reason among exclusive cigarette smokers was 0.37, whereas the proportion among exclusive waterpipe smokers was 0.04 and among dual smokers 0.39. The difference in proportions is significant, χ2 (df = 2, N = 154 = 13.17, p = 0.0014. In summary, this study supports the need to further investigate dual cigarette and waterpipe smokers, as the study results indicate greater barriers to smoking cessation in this group. Recognition and understanding of these barriers among dual tobacco users would be important for any future tobacco intervention among waterpipe smokers.

    Full Text Available BACKGROUND: We examined electronic cigarette (EC use, correlates of use, and associated changes in smoking behavior among smokers with serious mental illness in a clinical trial. METHODS: Adult smokers were recruited during acute psychiatric hospitalization (N = 956, 73% enrollment among approached smokers in the San Francisco Bay Area between 2009-2013. At baseline, participants averaged 17 (SD = 10 cigarettes per day for 19 (SD = 14 years; 24% intended to quit smoking in the next month. Analyses examined frequency and correlates of EC use reported over the 18-month trial and changes in smoking behavior by EC use status. FINDINGS: EC use was 11% overall, and by year of enrollment, increased from 0% in 2009 to 25% in 2013. In multiple logistic regression, the likelihood of EC use was significantly greater with each additional year of recruitment, for those aged 18-26, and for those in the preparation versus precontemplation stage of change, and unlikely among Hispanic participants. EC use was unrelated to gender, psychiatric diagnosis, and measures of tobacco dependence at baseline. Further, over the 18-month trial, EC use was not associated with changes in smoking status or, among continued smokers, with reductions in cigarettes per day. INTERPRETATION: Within a clinical trial with smokers with serious mental illness, EC use increased over time, particularly among younger adults and those intending to quit tobacco. EC use was unrelated to changes in smoking. The findings are of clinical interest and warrant further study.

    Full Text Available Objectives: Studies have correlated second hand smoke (SHS with many diseases, especially respiratory effects. The goal of this study was to measure the impact of SHS on the respiratory symptoms and exhaled carbon monoxide. Material and Methods: The study population consisted of 50 young workers in restaurants serving waterpipes, 48 university students who sit frequently in the university cafeteria where cigarette smoking is allowed and 49 university students spending time in places where smoking is not allowed. Subjects completed questionnaires on socio-demographic characteristics, respiratory symptoms and exposure to SHS. Exhaled carbon monoxide levels were measured. ANOVA and Chi-square tests were used when applicable as well as linear and logistic regression analysis. Results: Exposure to cigarette smoke in university (adjusted odds ratio (ORa = 6.06 and occupational exposure to waterpipe smoke (ORa = 7.08 were predictors of chronic cough. Being married (ORa = 6.40, living near a heavy traffic road (ORa = 9.49 or near a local power generator (ORa = 7.54 appeared responsible for chronic sputum production. Moreover, predictors of chronic allergies were: being male (ORa = 7.81, living near a local power generator (ORa = 5.52 and having a family history of chronic respiratory diseases (ORa = 17.01. Carbon monoxide levels were augmented by the number of weekly hours of occupational exposure to waterpipe smoke (β = 1.46 and the number of daily hours of exposure to cigarette smoke (β = 1.14. Conclusions: In summary, young non-smoker subjects demonstrated more chronic cough and elevated carbon monoxide levels when exposed to SHS while the effect of waterpipe was even more evident.

The prevalence of COPD among cigarette smokers in the Middle East is not well studied. A prospective descriptive study was performed in the north of Jordan. Male cigarette smokers (≥10 pack-year aged 35 years and older were recruited from the community. They completed a questionnaire and a postbronchodilator spirometry. Global Initiative for Chronic Obstructive Lung Disease (GOLD criteria (postbronchodilator forced expiratory volume in 1 second <70% was used to define COPD. A total of 512 subjects completed the study protocol. According to the GOLD criteria, 42 subjects (8.2% had COPD. Of those, 27 subjects (64.3% had symptomatic COPD. Using the GOLD criteria, eight subjects (19% with COPD had mild disease, 24 (57.1% had moderate disease, eight (19% had severe disease, and two (4.8% had very severe disease. Only 10.6% were aware of COPD as a smoking-related respiratory illness, and 6.4% had received counseling about risk for COPD by a physician. Chronic bronchitis (cough for 3 months in 2 consecutive years was reported by 15% of the subjects, wheezes by 44.1%, and dyspnea by 65.2%. Subjects with COPD reported having more chronic bronchitis 18/42 (42.9% and wheezing 28/42 (66.7% than subjects without COPD. The prevalence of COPD increased with increased number of pack-years smoked. In conclusion, COPD prevalence among cigarette-smoking men in Jordan is lower than in the developed world.

    Guided by the extended parallel process model (EPPM) and reactance theory, this study examined the relationship between efficacy beliefs, reactance, and adult smokers' responses to pictorial health warning labels (HWL) on cigarette packaging, including whether efficacy beliefs or reactance modify the relationship between HWL responses and subsequent smoking cessation behavior. Four waves of data were analyzed from prospective cohorts of smokers in Australia and Canada (n = 7,120 observations) over a period of time after implementation of more prominent, pictorial HWLs. Three types of HWL responses were studied: psychological threat responses (i.e., thinking about risks from smoking), forgoing cigarettes due to HWLs, and avoiding HWLs. The results from Generalized Estimating Equation models indicated that stronger efficacy beliefs and lower trait reactance were significantly associated with greater psychological threat responses to HWLs. Similar results were found for models predicting forgoing behavior, although response efficacy was inversely associated with it. Only response efficacy was significantly associated with avoiding HWLs, showing a positive relationship. Higher self-efficacy and stronger responses to HWLs, no matter the type, were associated with attempting to quit in the follow-up period; reactance was unassociated. No statistically significant interactions were found. These results suggest that stronger efficacy beliefs and lower trait reactance are associated with some stronger responses to fear-arousing HWL responses; however, these HWL responses appear no less likely to lead to cessation attempts among smokers with different levels of self-efficacy to quit, of response efficacy beliefs, or of trait reactance against attempts to control their behavior.

    Objective Some researchers have raised concerns that pictorial health warning labels (HWLs) on cigarette packages may lead to message rejection and reduced effectiveness of HWL messages. This study aimed to determine how state reactance (i.e., negative affect due to perceived manipulation) in response to both pictorial and text-only HWLs is associated with other types of HWL responses and with subsequent cessation attempts. Methods Survey data were collected every 4 months between September 2013 and 2014 from online panels of adult smokers in Australia, Canada, Mexico, and the US were analyzed. Participants with at least one wave of follow-up were included in the analysis (n = 4,072 smokers; 7,459 observations). Surveys assessed psychological and behavioral responses to HWLs (i.e., attention to HWLs, cognitive elaboration of risks due to HWLs, avoiding HWLs, and forgoing cigarettes because of HWLs) and cessation attempts. Participants then viewed specific HWLs from their countries and were queried about affective state reactance. Logistic and linear Generalized Estimating Equation (GEE) models regressed each of the psychological and behavioral HWL responses on reactance, while controlling for socio-demographic and smoking-related variables. Logistic GEE models also regressed having attempted to quit by the subsequent survey on reactance, each of the psychological and behavioral HWL responses (analyzed separately), adjustment variables. Data from all countries were initially pooled, with interactions between country and reactance assessed; when interactions were statistically significant, country-stratified models were estimated. Results Interactions between country and reactance were found in all models that regressed psychological and behavioral HWL responses on study variables. In the US, stronger reactance was associated with more frequent reading of HWLs and thinking about health risks. Smokers from all four countries with stronger reactance reported greater

    Full Text Available Tongue has taste buds that contain taste receptor which affected by many factors, including smoking habit. Objective: To analyze the differences of sweet and bitter taste sensitivity in the pedicab driver clove cigarette smokers compared to non-smokers in Medan Padang Bulan. Methods: This study was conducted by placing the sweet taste strips and bitter taste strips on four taste receptors of the tongue, with increasing solution concentration in 74 subjects. This was a cross sectional study on pedicab driver population in Medan Padang Bulan. Results: There were differences between clove cigarette smokers and non-smokers on sweet taste examination (p<0.005. There was a difference between clove cigarette smokers and non-smokers on examination bitter taste receptors (p<0.005. On the clove cigarette smokers, there was no significant difference between sweet taste and bitter taste on the receptors itself. Conclusion: Non-smokers are more sensitive to sweet taste than the clove cigarette smokers. Bitter taste sensitivity is greater in cigarettes smokers than in non-smokers. Taste receptors on all location of the tongue could taste sweet and bitter substances, but a certain location of taste receptors were more sensitive compared to others.

    To investigate the role of the tobacco industry in marketing to and sustaining tobacco addiction among older smokers and aging baby boomers, We performed archival searches of electronic archives of internal tobacco company documents using a snowball sampling approach. Analysis was done using iterative and comparative review of documents, classification by themes, and a hermeneutic interpretive approach to develop a case study. Based on extensive marketing research, tobacco companies aggressively targeted older smokers and sought to prevent them from quitting. Innovative marketing approaches were used. "Low tar" cigarettes were developed in response to the health concerns of older smokers, despite industry knowledge that such products had no health advantage and did not help smokers quit. Tobacco industry activities influence the context of cessation for older smokers in several ways. Through marketing "low tar" or "light" cigarettes to older smokers "at risk" of quitting, the industry contributes to the illusion that such cigarettes are safer, although "light" cigarettes may make it harder for addicted smokers to quit. Through targeted mailings of coupons and incentives, the industry discourages older smokers from quitting. Through rhetoric aimed at convincing addicted smokers that they alone are responsible for their smoking, the industry contributes to self-blame, a documented barrier to cessation. Educating practitioners, older smokers, and families about the tobacco industry's influence may decrease the tendency to "blame the victim," thereby enhancing the likelihood of older adults receiving tobacco addiction treatment. Comprehensive tobacco control measures must include a focus on older smokers.

    Cigarette smoking is an economically and epidemiologically expensive public health concern. Most adult smokers become addicted during adolescence, rendering it a crucial period for prevention and intervention. Although litigation claims have delayed implementation, graphic warning labels proposed by the U.S. Food and Drug Administration (FDA) may be a promising way to achieve this goal. We aimed to determine the efficacy of the labels in reducing in-scanner craving and to characterize the neurobiological responses in adolescent and adult smokers and non-smokers. While undergoing functional magnetic resonance imaging, thirty-nine 13- to 18-year-old adolescent and forty-one 25- to 30-year-old adult smokers and non-smokers rated their desire to smoke when presented with emotionally graphic warning labels and comparison non-graphic labels. Compared with adult smokers, adolescent smokers exhibited greater craving reduction in response to the warning labels. Although smokers evinced overall blunted recruitment of insula and dorsolateral prefrontal cortex (DLPFC) relative to non-smokers, an effect that was stronger in adolescent smokers, parametrically increasing activation of these regions was associated with greater craving reduction. Functional connectivity analyses suggest that greater DLPFC regulation of limbic regions predicted cigarette craving. These data underscore a prominent role of frontoinsular circuitry in predicting the efficacy of FDA graphic warning labels in craving reduction in adult and adolescent smokers.

The relationship of body mass index with smoking status was also assessed in current daily and intermittent smokers. The male subjects (N=240 of 20-30 years and 30-40 years age category were divided into four groups of 30 subjects each based on Global Adult Tobacco Survey Questionnaire, India as follows: Group 1 - Current daily cigarette smokers, Group 2 - current intermittent cigarette smokers, Group 3 - Second hand cigarette smokers and Group 4 - Non-smokers (Control group. One way ANOVA test showed non-significant differences between and within all the groups in body mass index (F=1.11, p>0.05 in 20-30 years age category. In 30-40 years age category, significant differences (F=4.11, p<0.05 were observed between and within all the groups. Post hoc Scheffe test in 30-40 years category also revealed significant mean differences between current daily smokers and non-smokers. Karl Pearson’s correlation test showed a highly significant inverse linear relationship (p<0.001 between pack years and BMI in both current daily and intermittent smokers. Current smoking of moderate intensity has an effect to alter relative fatness (or BMI of the body. There may be no substantial difference in BMI with moderate and light smoking as well as exposure to second-hand smoke (SHS in younger adults. The greater the number of cigarettes smoked, the lower the adult smoker's BMI in both current moderate and intermittent light smokers.

    Full Text Available BACKGROUND: To illustrate the burden of high cigarette excise taxes on low-income smokers. METHODOLOGY/PRINCIPAL FINDINGS: Using data from the New York and national Adult Tobacco Surveys from 2010-2011, we estimated how smoking prevalence, daily cigarette consumption, and share of annual income spent on cigarettes vary by annual income (less than $30,000; $30,000-$59,999; and more than $60,000. The 2010-2011 sample includes 7,536 adults and 1,294 smokers from New York and 3,777 adults and 748 smokers nationally. Overall, smoking prevalence is lower in New York (16.1% than nationally (22.2% and is strongly associated with income in New York and nationally (P<.001. Smoking prevalence ranges from 12.2% to 33.7% nationally and from 10.1% to 24.3% from the highest to lowest income group. In 2010-2011, the lowest income group spent 23.6% of annual household income on cigarettes in New York (up from 11.6% in 2003-2004 and 14.2% nationally. Daily cigarette consumption is not related to income. CONCLUSIONS/SIGNIFICANCE: Although high cigarette taxes are an effective method for reducing cigarette smoking, they can impose a significant financial burden on low-income smokers.

    The 2009 Family Smoking Prevention and Tobacco Control Act opened the possibility for tobacco companies to apply to market their products as having "modified" or reduced risks. However, research on how to communicate comparative tobacco risks and how such messages are interpreted is limited. This study aimed to qualitatively examine perceptions of potential modified risk statements presented as warning labels for e-cigarettes. We conducted six focus groups between 2014 and 2015 with 27 adult e-cigarette users and cigarette-only smokers who provided comments on two versions of a modified risk warning for e-cigarettes: 1) "WARNING: No tobacco product is safe, but this product presents substantially lower risks to health than cigarettes" (as proposed by two companies for their smokeless tobacco products) and 2) "WARNING: This product may be harmful to health, but is substantially less harmful than cigarettes" (an alternative developed by our team). Although most personally believed that e-cigarettes are safer than cigarettes and some thought the messages were true and accurate, many were skeptical and uncomfortable with the warnings because they did not "seem like a warning" and because use of the phrase "substantially lower risks" could be misleading and difficult to understand. Several thought the second warning was stronger (e.g., more active, more specific). Modified risk messages about e-cigarettes may impact perceptions and use of the product. More research is needed to identify the framing, wording and placement (e.g. within or in addition to a warning) that could potentially increase population-level benefits and minimize harms.

    Previous research has clearly demonstrated that smokers associate cigarette descriptors such as 'light', 'ultra-light' and 'low tar' with reduced health risks, despite evidence showing that cigarettes with these descriptor terms do not present lower health risk. In June 2010, regulations implemented by the US Food and Drug Administration went into effect to ban the use of 'light', 'mild' and 'low' on cigarette packaging. We surveyed smokers participating in human laboratory studies at our Center in Philadelphia, PA, USA shortly after the ban went into effect to determine the extent of awareness of recent cigarette packaging changes among smokers of light cigarettes. In our sample of 266 smokers, 76 reported smoking light cigarettes, but fewer than half of these smokers reported noticing changes to their cigarette packaging. Simple removal of a few misleading terms may be too subtle of a change to register with consumers of so-called 'low tar' cigarettes; more comprehensive regulation of cigarette packaging design may be necessary to gain smokers' attention and minimize misperceptions associated with tobacco pack design characteristics and color.

    This paper examines how Chinese smokers respond to tax-driven cigarette price increases by estimating a discrete choice model of demand for differentiated products, using annual nationwide brand-level cigarette sales data in China from 2005 to 2010. We allow for substitution between different cigarette brands and also incorporate key features of rational addiction theory into the model. Results show that the average own-price elasticity of demand for cigarettes at the brand level is -0.807, and the overall price elasticity of cigarettes at the market level is -0.488 in China. We find tax-induced substitution toward low-price cigarettes as well as high-tar cigarettes and that tax hikes encourage within-class substitution more than across-class substitution. These results have important policy implications for the potential effects of cigarette taxation. Copyright © 2014 John Wiley & Sons, Ltd. PMID:25044632

    Patients with pulmonary fibrosis frequently smoke cigarettes. The cause of dyspnea in these patients is often complex because of the coexistence of multiple disease processes. We investigated 10 cigarette smokers with pulmonary fibrosis who were referred for evaluation of new onset or worsening dyspnea. Chest radiographs and pulmonary function tests were obtained in addition to high-resolution computed tomography (HRCT). In those patients with HRCT evidence of both diseases, spirometry and lung volumes were most often normal. Although plain films provided a reasonable assessment of fibrosis, they underestimated the severity of emphysema. Quantitation of both emphysema and fibrosis by HRCT was reproducible and correlated with key pulmonary function tests. Our findings indicate that the HRCT scan is a useful diagnostic test in patients with pulmonary fibrosis who are also cigarette smokers.

    Objectives To describe older smokers’ perceptions of risks and use of e-cigarettes, and their responses to marketing and knowledge of, and opinions about, regulation of e-cigarettes. Methods Eight 90-minute focus groups with 8 to 9 participants met in urban and suburban California to discuss topics related to cigarettes and alternative tobacco products. Results Older adults are using e-cigarettes for cessation and as a way to circumvent no-smoking policies; they have false perceptions about the effectiveness and safety of e-cigarettes. They perceive e-cigarette marketing as a way to renormalize smoking. Conclusions To stem the current epidemic of nicotine addiction, the FDA must take immediate action because e-cigarette advertising promotes dual use and may contribute to the renormalization of smoking.

    Electronic cigarettes (e-cigarettes) are battery-powered devices that deliver a heated aerosol, which typically contains nicotine, flavorings, and other additives, to the user. The e-cigarette marketplace is rapidly evolving, but the long-term health effects of these products are not known. Carcinogens and toxins such as diacetyl, acetaldehyde, and other harmful chemicals have been documented in the aerosol from some e-cigarettes (1-3). On May 5, 2016, the Food and Drug Administration (FDA) finalized a rule extending its authority to all tobacco products, including e-cigarettes.* The prevalence of e-cigarette use among U.S. adults has increased in recent years, particularly among current and former conventional cigarette smokers (4); in 2014, 3.7% of all U.S. adults, including 15.9% of current cigarette smokers, and 22.0% of former cigarette smokers, used e-cigarettes every day or some days (5). The extent of current e-cigarette use among U.S. working adults has not been assessed. Therefore, CDC analyzed 2014 National Health Interview Survey (NHIS) data for adults aged ≥18 years who were working during the week before the interview, to provide national estimates of current e-cigarette use among U.S. working adults by industry and occupation. Among the estimated 146 million working adults, 3.8% (5.5 million) were current (every day or some days) e-cigarette users; the highest prevalences were among males, non-Hispanic whites, persons aged 18-24 years, persons with annual household income <$35,000, persons with no health insurance, cigarette smokers, other combustible tobacco users, and smokeless tobacco users. By industry and occupation, workers in the accommodation and food services industry and in the food preparation and serving-related occupations had the highest prevalence of current e-cigarette use. Higher prevalences of e-cigarette use among specific groups and the effect of e-cigarette use on patterns of conventional tobacco use underscore the importance

    The role of inhalation behaviors as predictors of nicotine uptake was examined in the Pennsylvania Adult Smoking Study (2012-2014), a study of 332 adults whose cigarette smoking was measured in a naturalistic environment (e.g., at home) with portable handheld topography devices. Piecewise regression analyses showed that levels of salivary cotinine, trans-3'-hydroxycotinine, and total salivary nicotine metabolites (cotinine + trans-3'-hydroxycotinine) increased linearly up to a level of about 1 pack per day (20 cigarettes per day (CPD)) (P < 0.01). Total daily puff volume (TDPV; in mL) (P < 0.05) and total daily number of puffs (P < 0.05), but not other topographical measures, increased linearly with CPD up to a level of about 1 pack per day. The mean level of cotinine per cigarette did not change above 20 CPD and was 36% lower in heavy smokers (≥20 CPD) than in lighter smokers (<20 CPD) (15.6 ng/mL vs. 24.5 ng/mL, respectively; P < 0.01). Mediation models showed that TDPV accounted for 43%-63% of the association between CPD and nicotine metabolites for smokers of <20 CPD. TDPV was the best predictor of nicotine metabolite levels in light-to-moderate smokers (1-19 CPD). In contrast, neither CPD, total daily number of puffs, nor TDPV predicted nicotine metabolite levels above 20 CPD (up to 40 CPD). Finally, although light smokers are traditionally considered less dependent on nicotine, these findings suggest that they are exposed to more nicotine per cigarette than are heavy smokers due to more frequent, intensive puffing.

    The traditional view that excise taxes are regressive has been challenged. I document the history of the term regressive tax, show that traditional definitions have always found cigarette taxes to be regressive, and illustrate the implications of the greater price responsiveness observed among the poor. I explain the different definitions of tax burden: accounting, welfare-based willingness to pay, and welfare-based time inconsistent. Progressivity (equity across income groups) is sensitive to the way in which tax burden is assessed. Analysis of horizontal equity (fairness within a given income group) shows that cigarette taxes heavily burden poor smokers who do not quit, no matter how tax burden is assessed.

    Leg lymphatic segments were isolated from 10 patients (4 cigarette smokers and 6 non-smokers) undergoing conventional lymphography. Prostaglandin (PG) levels and PG synthesis in the lymphatics and in a variety of body fluids and the effects of eicosanoids on lymphatic contractility were determined. Leg lymphatics from 4 smokers generated less PGI2 and contained more 8-epi-PGF2 alpha when compared with leg lymphatics in 6 non-smokers. Similarly, levels of 8-epi-PGF2 alpha in smokers compared with non-smokers were higher in plasma (28.6 cf 19.7 pg/ml), leg lymph (146.7 cf 65.3 pg/ml), serum (299.0 cf 204.1 pg/ml), and urine (473.4 cf 241.0 pg/mg creatinine). Lymphatics from smokers also showed a higher contractile response, less 14C-arachidonic acid conversion to PGI2 and less PGI2-formation with various stimuli compared with non-smokers. Together these findings suggest that smoking induces oxidation injury, promotes altered (iso-)eicosanoid production and impacts on the function and dysfunction of peripheral lymphatics under normal circumstances and in a variety of clinical disorders.

    Full Text Available Background: Smoking is a major public health problem, especially in Iraq. There is very little information had been documented regarding smoking risk factors and quit intention among Iraqi smokers. Objectives: The main objectives of this study are to determine smokers' knowledge and perception about smoking health risks; and to determine smoking behavior and quitting intentions among Iraqi smokers; as well as to predict the factors that may associate with quit intentions. Methods: A cross-sectional study was conducted at the outpatient clinic in Tikrit Teaching Hospital, Tikrit City, Iraq. Adult smokers who are smoking cigarette everyday and able to communicate with the researcher were invited to participate in the study. A self-administered questionnaire was used to collect data from 386 participants. Results: This study showed that smokers had low awareness about some risk effects of smoking such as lung cancer in nonsmokers (30.1%, impotence in male smokers (52.6%, premature ageing (64%, and stroke (66.3%. In addition, the high score of knowledge and perception was significantly associated with quitting intention. Conclusion: Smokers' knowledge and perception regarding smoking health effects were low, especially in terms of secondhand smokers. Many efforts needed from health policy-makers and health care professionals to disseminate information about the risks of smoking and health benefits of give up smoking.

    HIV-positive populations have high smoking rates and smoking puts HIV-positive individuals at higher risk for HIV-related health problems. Little information is available on the characteristics of HIV-positive smokers. The present study examines the baseline psychosocial characteristics of 184 HIV-positive cigarette smokers enrolled in a smoking cessation clinical trial. The sample was 82% male, and 53% Caucasian. Over half were unemployed and 43.8% reported an income of less than $10,000. Mean cigarettes per day was 19.2 and the mean Fagerström Test Nicotine Dependence score was 4.8. The majority reported a strong desire to quit however, only 45% endorsed a goal of complete abstinence. On average, 43.2% of the smokers' social support was made up of other smokers. Both licit and illicit drug use was common and there were significant rates of lifetime psychiatric diagnoses in this cohort of smokers. It is critical to evaluate interventions that consider the specific needs of this group. PMID:19537954

  5. Disordered microbial communities in the upper respiratory tract of cigarette smokers.

    Full Text Available Cigarette smokers have an increased risk of infectious diseases involving the respiratory tract. Some effects of smoking on specific respiratory tract bacteria have been described, but the consequences for global airway microbial community composition have not been determined. Here, we used culture-independent high-density sequencing to analyze the microbiota from the right and left nasopharynx and oropharynx of 29 smoking and 33 nonsmoking healthy asymptomatic adults to assess microbial composition and effects of cigarette smoking. Bacterial communities were profiled using 454 pyrosequencing of 16S sequence tags (803,391 total reads, aligned to 16S rRNA databases, and communities compared using the UniFrac distance metric. A Random Forest machine-learning algorithm was used to predict smoking status and identify taxa that best distinguished between smokers and nonsmokers. Community composition was primarily determined by airway site, with individuals exhibiting minimal side-of-body or temporal variation. Within airway habitats, microbiota from smokers were significantly more diverse than nonsmokers and clustered separately. The distributions of several genera were systematically altered by smoking in both the oro- and nasopharynx, and there was an enrichment of anaerobic lineages associated with periodontal disease in the oropharynx. These results indicate that distinct regions of the human upper respiratory tract contain characteristic microbial communities that exhibit disordered patterns in cigarette smokers, both in individual components and global structure, which may contribute to the prevalence of respiratory tract complications in this population.

    Executive Summary Raising the price of cigarettes is one of the most effective interventions to prevent and reduce cigarette use. Local, state, and federal governments can change the price of cigarettes by raising or lowering cigarette excise taxes and by implementing and enforcing minimum price laws. Smokers can also adjust their behavior by choosing discount or “bargain” brands, buying fewer cigarettes, and avoiding paying cigarette taxes by purchasing from retailers that do not le...

    Full Text Available Objectives: Electronic cigarette (e-cigarette use is increasing in the U.S. Although marketed as a safer alternative for cigarettes, initial evidence suggests that e-cigarettes may pose a secondhand exposure risk. The current study explored the prevalence and correlates of support for e-cigarette bans. Methods: A sample of 265 current/former smokers completed a cross-sectional telephone survey from June–September 2014; 45% Black, 31% White, 21% Hispanic. Items assessed support for home and workplace bans for cigarettes and e-cigarettes and associated risk perceptions. Results: Most participants were aware of e-cigarettes (99%. Results demonstrated less support for complete e-cigarette bans in homes and workplaces compared to cigarettes. Support for complete e-cigarette bans was strongest among older, higher income, married respondents, and former smokers. Complete e-cigarette bans were most strongly endorsed when perceptions of addictiveness and health risks were high. While both e-cigarette lifetime and never-users strongly supported cigarette smoking bans, endorsement for e-cigarette bans varied by lifetime use and intentions to use e-cigarettes. Conclusions: Support for indoor e-cigarette bans is relatively low among individuals with a smoking history. Support for e-cigarette bans may change as evidence regarding their use emerges. These findings have implications for public health policy.

    Quest cigarettes are a relatively new (2003) product that has been marketed as a way for smokers to gradually reduce the nicotine they receive from cigarettes in order to, according to marketing materials, become nicotine free. However, despite lower levels of nicotine, Quest cigarettes do not have reduced tar levels and, thus, still pose health hazards. This study evaluated beliefs about Quest cigarettes following exposure to a single print advertisement among 200 regular smokers who had never heard of the brand itself. Descriptively, smokers made several specific false inferences about Quest cigarettes after exposure (i.e., lower in tar, healthier, less likely to cause cancer). Two individual-differences variables, need for cognition and perceived vulnerability, moderated smokers' health beliefs about Quest cigarettes. PMID:16536669

Data are from a mail survey of a population-based sample of adults aged 18 to 35 (N = 4740 in three U.S. metropolitan areas. Survey items assessed trial and use of e-cigarettes, cigarette smoking status, and reasons for trial and for ceasing use of e-cigarettes. Almost 23% reported trial of e-cigarettes, and 8.4% reported using them in the past month. Current smokers were much more likely to have tried e-cigarettes (70.2% than both former (32.3% and never smokers (7.6%; p < 0.001 and to have used them in the past month (30.8%, 10.1%, 2.0% respectively; p < 0.001. Smoking status and scores on sensation seeking were significant independent predictors of both trial and current use of e-cigarettes. Never-smokers cite curiosity as the reason for trying e-cigarettes and also that their friends used them. The most frequent reason for ceasing use among never and former smokers was health concerns. For virtually none of them were e-cigarettes their first exposure to nicotine.

    Full Text Available Electronic cigarettes (e-cigarettes are being increasingly used. We examined the correlates associated with e-cigarette awareness, use and perceived effectiveness in smoking cessation among Chinese daily smokers in Hong Kong.Daily smokers (N = 1,307 were recruited to a community-based randomised controlled trial ('Quit to Win' in 2014. Socio-demographic characteristics, conventional cigarette smoking status, nicotine addiction level, quit attempts, quit intention, e-cigarette awareness, use and perceived effectiveness on quitting were reported at baseline and 1-week follow-up. Multivariate logistic regression was used to identify factors associated with e-cigarette awareness, use and perceived effectiveness in quitting.Most smokers (82.6%, 95% CI 80.2%-84.9% had heard about e-cigarettes, and 13.3% (11.3%-15.5% ever used e-cigarettes. Most users (74.1% and non-users (91.2% did not perceive e-cigarettes as effective in quitting. Being younger and having a larger family income were associated with e-cigarette awareness. Being younger, a tertiary education and a stronger addiction to nicotine were associated with e-cigarette use, which was itself associated with lower levels of intention to quit and had no association with attempts to quit (P for trend 0.45. E-cigarette use, the last quit attempt being a month earlier, having made a quit attempt lasting 24 hours or longer and perceiving quitting as important were all associated with the perceived effectiveness of e-cigarettes in quitting (all P <0.05.Among community-recruited smokers who intended to quit, awareness of e-cigarettes was high, but most did not perceive e-cigarettes as effective in quitting. Correlates concerning e-cigarette perceptions and use will help to inform prospective studies, public education and policy on controlling e-cigarettes.

    Cigarette smoking is associated with various cutaneous disorders with defective permeability. Yet, whether cigarette smoking influences epidermal permeability barrier function is largely unknown. Here, we measured skin biophysical properties, including permeability barrier homeostasis, stratum corneum (SC) integrity, SC hydration, skin surface pH, and skin melanin/erythema index, in cigarette smokers. A total of 99 male volunteers were enrolled in this study. Smokers were categorized as light-to-moderate (melanin/erythema index on the dorsal hand, forehead, and cheek. Basal transepidermal water loss (TEWL) and barrier recovery rates were assessed on the forearm. A Skin-pH-Meter pH900 was used to measure skin surface pH. Our results showed that heavy cigarette smokers exhibited delayed barrier recovery after acute abrogation (1.02% ± 13.06 versus 16.48% ± 6.07), and barrier recovery rates correlated negatively with the number of daily cigarettes consumption (p = 0.0087). Changes in biophysical parameters in cigarette smokers varied with body sites. In conclusion, heavy cigarette smokers display compromised permeability barrier homeostasis, which could contribute, in part, to the increased prevalence of certain cutaneous disorders characterized by defective permeability. Thus, improving epidermal permeability barrier should be considered for heavy cigarette smokers. PMID:27437403

    Preliminary evidence, within both adults and adolescents, suggests that the intensity with which cigarettes are smoked (i.e., smoking topography) is predictive of success during a cessation attempt. These reports have also shown topography to be superior compared to other variables, such as cigarettes per day, in the prediction of abstinence. The possibility that gender may influence this predictive relationship has not been evaluated but may be clinically useful in tailoring gender-specific interventions. Within the context of a clinical trial for smoking cessation among women, adult daily smokers completed a laboratory session that included a 1-hour ad libitum smoking period in which measures of topography were collected (N=135). Participants were then randomized to active medication (nicotine patch vs. varenicline) and abstinence was monitored for 4weeks. Among all smoking topography measures and all abstinence outcomes, a moderate association was found between longer puff duration and greater puff volume and continued smoking during the active 4-week treatment phase, but only within the nicotine patch group. Based on the weak topography-abstinence relationship among female smokers found in the current study, future studies should focus on explicit gender comparisons to examine if these associations are specific to or more robust in male smokers.

    Full Text Available Abstract Background Previous cross-sectional research has suggested single cigarettes could either promote or inhibit consumption. The present study aimed to assess the effects of single cigarette availability and consumption on downstream quit behavior. Methods We analyzed population-based, longitudinal data from adult smokers who participated in the 2008 and 2010 administrations of the International Tobacco Control Policy Evaluation Survey in Mexico. Results At baseline, 30% of smokers saw single cigarettes for sale on a daily basis, 17% bought singles at their last purchase, and 7% bought singles daily. Smokers who most frequently purchased singles, both in general and specifically to control their consumption, were no more likely to attempt to quit over the 14 month follow-up period than those who did not purchase singles. Frequency of buying singles to reduce consumption had a non-monotonic association with being quit at followup. The odds of being quit was only statistically significant when comparing those who had not bought singles to reduce consumption with those who had done so on a more irregular basis (AOR = 2.30; 95% CI 1.19, 4.45, whereas those who did so more regularly were no more likely to be quit at followup. Frequency of self-reported urges to smoke upon seeing singles for sale was unassociated with either quit attempts or being quit at followup. Conclusions These results suggest that the relationship between singles consumption and quit behavior is complex, with no clear evidence that singles either promote or inhibit downstream quit behavior.

    Cigarette tax increases result in a reduced demand for cigarettes and increased efforts by smokers to reduce their cost of smoking. Less is known about how smokers think about their expenditures for cigarettes and the possible mechanisms that underlie price-minimizing behaviors. In-depth longitudinal interviews were conducted with Minnesota smokers to explore the factors that influence smokers' decisions one month prior to a $1.75 cigarette tax increase and again one and three months after the increase. A total of 42 were sampled with 35 completed interviews at all three time points, resulting in 106 interviews across all participants at all time points. A qualitative descriptive approach examined smoking and buying habits, as well as reasons behind these decisions. A hierarchy of ways to save money on cigarettes included saving the most money by changing to roll your own pipe tobacco, changing to a cheaper brand, cutting down or quitting, changing to cigarillos, and buying online. Using coupons, shopping around, buying by the carton, changing the style of cigarette, and stocking up prior to the tax increase were described as less effective. Five factors emerged as impacting smokers' efforts to save money on cigarettes after the tax: brand loyalty, frugality, addiction, stress, and acclimation. PMID:27322301

    Full Text Available Objective: To compare the periodontal bone height (PBH of exclusive narghile smokers (ENS with that of exclusive cigarette smokers (ECS. Methods: Tunisian males aged 20–35 years who have been ENS for more than five narghile-years or ECS for more than five pack-years were recruited to participate in this comparative cross-sectional study. Information about oral health habits and tobacco consumption were gathered using a predetermined questionnaire. Plaque levels were recorded in four sites using the plaque index of Loe and Silness. The PBH was measured mesially and distally from digital panoramic radiographs of each tooth and expressed as a percentage of the root length. A PBH level ≤0.70 was applied as a cutoff reference value signifying bone loss. Student t-test and Chi2 test were used to compare quantitative and qualitative data of both groups. Results: There were no significant differences between the ENS (n=60 and ECS (n=60 groups regarding age and the consumed quantities of tobacco (28±4 vs. 27±5 years, 7±3 narghile-years vs. 8±3 pack-years, respectively. Compared with the ECS group, the ENS group had a significantly higher plaque index (mean±SD values were 1.54±0.70 vs. 1.84±0.73, respectively. However, the two groups had similar means of PBH (0.85±0.03 vs. 0.86±0.04 and tooth brushing frequencies (1.1±0.8 vs. 0.9±0.6 a day, respectively and had similar bone loss frequencies (15% vs. 12%, respectively. Conclusions: Both ENS and ECS exhibited the same PBH reduction, which means that both types of tobacco smoking are associated with periodontal bone loss.

    Electronic cigarette (e-cigarette) use is becoming increasing popular among smokers, and there is a plethora of devices available. Nicotine delivery is clearly important for reducing tobacco craving and withdrawal symptoms, but other sensorimotor aspects of e-cigarettes (such as visual appearance) may contribute to this effect. This study explored whether it is important for an e-cigarette to visually resemble a tobacco cigarette in order to reduce craving and withdrawal symptoms. Sixty-three cigarette smokers (40% female, aged 18-65 years) who were not current e-cigarette users were randomly allocated to take ten 3-s puffs from either a white or a red first-generation e-cigarette following overnight abstinence. Current craving (urge to smoke) and nicotine withdrawal symptoms (using the Mood and Physical Symptoms Scale [MPSS]) were measured before and 10 min after use. Linear regression revealed higher craving and withdrawal symptoms in the red condition versus the white condition, but only among those who were e-cigarette naive (craving: B = .76, p = .009; withdrawal symptoms: B = 2.18, p = .009), not among those with e-cigarette experience (craving: B = -.08, p = .89; withdrawal symptoms: B = .24, p = .81), and these effects differed between groups (p = .04 and 0.01 for craving and withdrawal symptoms, respectively). In conclusion, cigarette-like appearance was associated with lower craving and withdrawal symptoms, but only for those with no prior e-cigarette experience. This effect, putatively mediated via classical conditioning or expectancies, may aid understanding of smokers' initial preferences for "cigalike" e-cigarette devices.

  2. The neural mechanisms underlying the acute effect of cigarette smoking on chronic smokers.

    Full Text Available Although previous research had related structural changes and impaired cognition to chronic cigarette smoking, recent neuroimaging studies have associated nicotine, which is a main chemical substance in cigarettes, with improvements in cognitive functions (e.g. improved attention performance. However, information about the alterations of whole-brain functional connectivity after acute cigarette smoking is limited. In this study, 22 smokers underwent resting-state functional magnetic resonance imaging (rs-fMRI after abstaining from smoking for 12 hours (state of abstinence, SOA. Subsequently, the smokers were allowed to smoke two cigarettes (state of satisfaction, SOS before they underwent a second rs-fMRI. Twenty non-smokers were also recruited to undergo rs-fMRI. In addition, high-resolution 3D T1-weighted images were acquired using the same magnetic resonance imaging(fMRIscanner for all participants. The results showed that smokers had structural changes in insula, thalamus, medial frontal cortex and several regions of the default mode network (DMN compared with non-smokers. Voxel-wise group comparisons of newly developed global brain connectivity (GBC showed that smokers in the SOA condition had higher GBC in the insula and superior frontal gyrus compared with non-smokers. However, smokers in the SOS condition demonstrated significantly lower GBC in several regions of the DMN, as compared with smokers in the SOA condition. These results suggest that structural integrity combined with dysfunction of the DMN might be involved in relapses after a short period of time among smokers.

This cross-sectional study reports on data collected at baseline from hospitalized cigarette smokers (N=944) recruited in monthly cohorts between December 2012 and September 2013. Participants were queried regarding e-cigarette awareness and use, and number and sources of e-cigarette advertisement exposures in the previous 6 months. Most Whites (99%) reported ever hearing of an e-cigarette compared to 96% of Blacks (padvertisement exposure reported for the previous 6 months, with a 14% increase each month (padvertisement exposure than Blacks (mean=25 vs. 8 in month 1 to 79 vs. 45 in month 9, respectively; padvertisement exposure was significantly associated with e-cigarette use (padvertisement exposure from stores and the Internet, and Blacks reported more advertisement exposure from radio or television. Results suggest that e-cigarette marketing is beginning to breach the Black population who are, as a consequence, "catching up" with Whites with regard to e-cigarette use. Given the significant disparities for smoking-related morbidity and mortality between Blacks and Whites, these findings identify new areas for future research and policy. PMID:25503053

    Cigarette smoking in college is often described as social smoking, but the term lacks definition and implicitly discounts dependence. We report on college students' use of the terms social smoker and smoker. Students who currently smoked cigarettes were asked whether they considered themselves smokers, and whether they smoked because they were social smokers. The survey was conducted during 1999-2004 at eight colleges; analysis was limited to 1,401 students aged 18-24 years. More than half of students (56.3%) denied being smokers ("deniers") despite current smoking behavior. Half of deniers, and fewer than half of admitters, called themselves social smokers. Deniers were highly likely to smoke infrequently, to say they were not addicted to cigarettes, to have mostly nonsmokers as close friends, to prefer dating nonsmokers, and to smoke for reasons other than stress relief. In contrast, social-smoker identity was associated only weakly with any attitude, behavior, or belief. Smoker and social-smoker identities were not significantly correlated with each other. Regardless of identity, more than half of the respondents wanted to quit smoking by graduation. Results suggest that denying being a smoker may be a widespread dissonance among college students who smoke. The possibility should be evaluated using population-level research, because it has potentially undermining implications for smoking cessation campaigns. Campus health centers should avoid using "smoker" self-assessment items on pre-exam questionnaires. Further research is needed to explore the psychosocial mechanisms involved with denier identity, to clarify the implications for public health communications, and to develop appropriate intervention strategies.

    Behavioral inhibitory control has been shown to play an important role in a variety of addictive behaviors. A number of studies involving the use of Go/NoGo and stop-signal paradigms have shown that smokers have reduced response inhibition for cigarette-related cues. However, it is not known whether male light smokers' response inhibition for cigarette-related cues is lower than that of non-smokers in the two-choice oddball paradigm. The objective of the current study was to provide further behavioral evidence of male light smokers' impaired response inhibition for cigarette-related cues, using the two-choice oddball paradigm. Sixty-two male students (31 smokers, 31 non-smokers), who were recruited via an advertisement, took part in this two-choice oddball experiment. Cigarette-related pictures (deviant stimuli) and pictures unrelated to cigarettes (standard stimuli) were used. Response inhibition for cigarette-related cues was measured by comparing accuracy (ACC) and reaction time (RT) for deviant and standard stimuli in the two groups of subjects. An analysis of variance (ANOVA) showed that in all the participants, ACC was significantly lower for deviant stimuli than for standard stimuli. For deviant stimuli, the RTs were significantly longer for male light smokers than for male non-smokers; however, there was no significant difference in RTs for standard stimuli. Compared to male non-smokers, male light smokers seem to have a reduced ability to inhibit responses to cigarette-related cues. PMID:26528200

    Full Text Available Electronic cigarettes (e-cigarettes use is becoming increasingly common, especially among adolescents and young adults, and there is little evidence on the impact of e-cigarettes use on never-smokers. With a meta-analysis method, we explore the association between e-cigarettes use and smoking intention that predicts future cigarette smoking. Studies were identified by searching three databases up to January 2016. The meta-analysis results were presented as pooled odds ratio (OR with 95% confidence interval (CI calculated by a fixed-effects model. A total of six studies (91,051 participants, including 1452 with ever e-cigarettes use were included in this meta-analysis study. We found that never-smoking adolescents and young adults who used e-cigarettes have more than 2 times increased odds of intention to cigarette smoking (OR = 2.21, 95% CI: 1.86–2.61 compared to those who never used, with low evidence of between-study heterogeneity (p = 0.28, I2 = 20.1%. Among never-smoking adolescents and young adults, e-cigarettes use was associated with increased smoking intention.

    Electronic cigarettes (e-cigarettes) use is becoming increasingly common, especially among adolescents and young adults, and there is little evidence on the impact of e-cigarettes use on never-smokers. With a meta-analysis method, we explore the association between e-cigarettes use and smoking intention that predicts future cigarette smoking. Studies were identified by searching three databases up to January 2016. The meta-analysis results were presented as pooled odds ratio (OR) with 95% confidence interval (CI) calculated by a fixed-effects model. A total of six studies (91,051 participants, including 1452 with ever e-cigarettes use) were included in this meta-analysis study. We found that never-smoking adolescents and young adults who used e-cigarettes have more than 2 times increased odds of intention to cigarette smoking (OR = 2.21, 95% CI: 1.86-2.61) compared to those who never used, with low evidence of between-study heterogeneity (p = 0.28, I² = 20.1%). Among never-smoking adolescents and young adults, e-cigarettes use was associated with increased smoking intention.

    Tobacco smoking is the leading cause of preventable disease and death in the United States, resulting in approximately 480,000 premature deaths and more than $300 billion in direct health care expenditures and productivity losses each year (1). To assess progress toward achieving the Healthy People 2020 objective of reducing the percentage of U.S. adults who smoke cigarettes to ≤12.0%,* CDC assessed the most recent national estimates of smoking prevalence among adults aged ≥18 years using data from the 2014 National Health Interview Survey (NHIS). The percentage of U.S. adults who smoke cigarettes declined from 20.9% in 2005 to 16.8% in 2014. Among daily cigarette smokers, declines were observed in the percentage who smoked 20–29 cigarettes per day (from 34.9% to 27.4%) or ≥30 cigarettes per day (from 12.7% to 6.9%). In 2014, prevalence of cigarette smoking was higher among males, adults aged 25–44 years, multiracial persons and American Indian/Alaska Natives, persons who have a General Education Development certificate, live below the federal poverty level, live in the Midwest, are insured through Medicaid or are uninsured, have a disability or limitation, or are lesbian, gay, or bisexual. Proven population-based interventions, including tobacco price increases, comprehensive smoke-free laws, high impact mass media campaigns, and barrier-free access to quitting assistance, are critical to reduce cigarette smoking and smoking-related disease and death among U.S. adults.

    Studies have suggested a link between exposure to tobacco advertising and cigarette brand preference. Knowing the brand preferences of young established smokers can provide insight into what influences young smokers to start and continue to smoke. A report of 2005 data indicated that the three most heavily advertised brands, Marlboro, Newport, and Camel, were preferred by 81% of U.S. youths aged 12-17 years. To assess the cigarette brand preferences among middle school and high school students who were established smokers, CDC analyzed data from the 2004 and 2006 National Youth Tobacco Survey (NYTS). This report summarizes the results of that analysis, which indicated that among established student smokers in middle and high school, Marlboro was the preferred brand (43.3% and 52.3%, respectively), followed by Newport (26.4% and 21.4%, respectively). The use of Newport was significantly higher among blacks in middle school (59.7%) and high school (78.6%) compared with other racial/ethnic groups. Information on brand preferences and tobacco marketing strategies that are attractive to students can be used by tobacco control programs and community initiatives in the design of tobacco countermarketing campaigns. These countermarketing campaigns have been shown to be effective as part of a comprehensive tobacco control program to decrease the initiation of tobacco use among youths and young adults.

    Full Text Available Cigarette smoke-induced oxidative stress leads to dyslipidemia and systemic inflammation. Morinda citrifolia (noni fruit juice has been found previously to have a significant antioxidant activity. One hundred thirty-two adult heavy smokers completed a randomized, double blind, placebo-controlled clinical trial designed to investigate the effect of noni juice on serum cholesterol, triglyceride, low density lipoprotein cholesterol (LDL, high density lipoprotein cholesterol (HDL, high-sensitivity C-reactive protein (hs-CRP, and homocysteine. Volunteers drank noni juice or a fruit juice placebo daily for one month. Drinking 29.5 mL to 188 mL of noni juice per day significantly reduced cholesterol levels, triglycerides, and hs-CRP. Decreases in LDL and homocysteine, as well increases in HDL, were also observed among noni juice drinkers. The placebo, which was devoid of iridoid glycosides, did not significantly influence blood lipid profiles or hs-CRP. Noni juice was able to mitigate cigarette smoke-induced dyslipidemia, an activity associated with the presence of iridoids.

    Full Text Available Behavioral inhibitory control has been shown to play an important role in a variety of addictive behaviors. A number of studies involving the use of Go/No-Go and stop-signal paradigms have shown that smokers have reduced response inhibition for cigarette-related cues. However, it is not known whether smokers’ response inhibition for cigarette-related cues is lower than that of non-smokers in the two-choice oddball paradigm. The objective of the current study was to provide further behavioral evidence of male smokers’ impaired response inhibition for cigarette-related cues, using the two-choice oddball paradigm. Sixty-two male students (31 smokers, 31 non-smokers, who were recruited via an advertisement, took part in this two-choice oddball experiment. Cigarette-related pictures (deviant stimuli and pictures unrelated to cigarettes (standard stimuli were used. Response inhibition for cigarette-related cues was measured by comparing accuracy (ACC and reaction time (RT for deviant and standard stimuli in the two groups of subjects. An analysis of variance (ANOVA showed that in all the participants, ACC was significantly lower for deviant stimuli than for standard stimuli. For deviant stimuli, the RTs were significantly longer for male smokers than for male non-smokers; however, there was no significant difference in RTs for standard stimuli. Compared to male non-smokers, male smokers seem to have a reduced ability to inhibit responses to cigarette-related cues.

    Elevated rates of cigarette smoking have been reported among individuals with Bulimia Nervosa. However, little is known about eating disorder symptoms within non-clinical samples of smokers. The purpose of the present study was to compare the eating disorder symptoms of young adult female smokers (n=184) and non-smokers (n=56), to determine whether smokers were more likely to endorse bulimic symptoms and report greater body shape concern than non-smokers. Analyses indicated that smokers scored significantly higher than non-smokers on the Body Shape Questionnaire, p=.03, and the Bulimia Test-Revised, p=.006. In addition, a higher proportion of smokers than non-smokers scored > or = 85 on the Bulimia Test-Revised, p=.05, suggesting the possibility that Bulimia Nervosa diagnoses were more prevalent among smokers. No differences were found between smokers and non-smokers on other measures of eating behavior. Overall, findings suggest that smoking is specifically associated with symptoms of Bulimia Nervosa and body shape concern among young adult females.

    Tobacco use in nondependent smokers (i.e. chippers) is believed to be largely determined by situational factors including social context. However, little empirical research has examined how different social contexts impact chippers' smoking behaviour. Twenty-eight (16 men) chippers completed two laboratory sessions where they were offered an opportunity to self-administer puffs of their preferred tobacco brand using a progressive ratio task. During an individual session, participants self-administered cigarettes alone and during a paired session, they self-administered cigarettes with a coparticipant who was also smoking. The strongest predictors for number of self-administered puffs and breakpoint during the paired session were coparticipants' number of puffs and breakpoint, respectively (P<0.001), followed by puffs taken and breakpoint during the individual session (P<0.01). Current smoking frequency (cigarettes/week) did not significantly predict puffs taken or breakpoint during the paired session. Latency to cigarette self-administration during the paired session was correlated positively with coparticipants' latency (P<0.05), but not with latency during the individual session or cigarettes per week. The findings suggest that the presence of another smoker exerts an important influence on the quantity of chippers' smoking behaviour, such that chippers match their smoking behaviour to that of other smokers in their proximate environment.

    Visual depictions of vaping in electronic cigarette advertisements may serve as smoking cues to smokers and former smokers, increasing urge to smoke and smoking behavior, and decreasing self-efficacy, attitudes, and intentions to quit or abstain. After assessing baseline urge to smoke, 301 daily smokers, 272 intermittent smokers, and 311 former smokers were randomly assigned to view three e-cigarette commercials with vaping visuals (the cue condition) or without vaping visuals (the no-cue condition), or to answer unrelated media use questions (the no-ad condition). Participants then answered a posttest questionnaire assessing the outcome variables of interest. Relative to other conditions, in the cue condition, daily smokers reported greater urge to smoke a tobacco cigarette and a marginally significantly greater incidence of actually smoking a tobacco cigarette during the experiment. Former smokers in the cue condition reported lower intentions to abstain from smoking than former smokers in other conditions. No significant differences emerged among intermittent smokers across conditions. These data suggest that visual depictions of vaping in e-cigarette commercials increase daily smokers' urge to smoke cigarettes and may lead to more actual smoking behavior. For former smokers, these cues in advertising may undermine abstinence efforts. Intermittent smokers did not appear to be reactive to these cues. A lack of significant differences between participants in the no-cue and no-ad conditions compared to the cue condition suggests that visual depictions of e-cigarettes and vaping function as smoking cues, and cue reactivity is the mechanism through which these effects were obtained.

    Filter vent blocking on best-selling light cigarettes increases smoke yield during standard machine testing but not in clinical investigations of smokers. The purpose of the study was to investigate the effect of (a) manipulating cigarette filter vent blocking and (b) blocking status of first cigarette of the day on carbon monoxide (CO) boost. Participants (n = 25; Marlboro Lights nonmenthol cigarette smokers, age range 21-60 years, minimum 15 daily cigarettes, and daily smoking for a minimum 5 years) completed the laboratory-based, within-subject, double-blind, cross-over design of 2 smoking sessions, one utilizing a smoking topography device, one without. Each session consisted of smoking 4 cigarettes; 2 with filter vents blocked and 2 with filter vents unblocked. Spent first daily cigarette filters collected between sessions were scored for evidence of filter vent blocking. Smoking cigarettes with blocked filter vents significantly increased CO boost in both laboratory sessions (p < .001). Those who blocked their first cigarette of the day (n = 10) had significantly greater CO boost when smoking a blocked cigarette, in relation to smoking an unblocked cigarette and in comparison with nonblockers (p = .04). Total puff volume was a significant predictor of CO boost when smoking unblocked and blocked cigarettes (ps < .04). Blocking filter vents significantly increased smoke exposure in relation to when filter vents are not blocked, particularly for those who block filter vents on their first cigarette of the day. Total puff volume predicted CO boost, and results suggest that smokers adjust their smoking behavior by cigarette blocking status. Those smokers who block filter vents may be increasing their exposure by 30%. PMID:19968405

    Cigarette smoking is associated with elevated risk of anxiety and mood disorder. Using the 7.5% carbon dioxide (CO2) inhalation model of anxiety induction, we examined the effects of smoking status and abstinence from smoking on anxiety responses. Physiological and subjective responses to CO2 and medical air were compared in smokers and non-smokers (Experiment One) and in overnight abstinent and non-abstinent smokers (Experiment Two). CO2 induced greater increases in blood pressure in non-smokers compared with smokers (ps < 0.043), and greater increases in anxiety (p = 0.005) and negative affect (p = 0.054) in non-abstinent compared with abstinent smokers. CO2 increased physiological and subjective indices of anxiety. There were differences across smoking groups indicating that the CO2 inhalation model is a useful tool for examining the relationship between smoking and anxiety. The findings suggested that both acute smoking and acute abstinence may protect against anxious responding. Further investigation is needed in long-term heavy smokers. PMID:24763184

    Despite depressive symptoms being very common among smokers from the general population, few studies have examined the effects of depressive symptoms on smoking treatment outcomes, and even less research has been carried out in the context of contingency management (CM). The authors conducted a secondary analysis to assess the interrelation between treatment condition, depressive symptoms and treatment outcomes among treatment-seeking smokers. The sample was made up of 147 treatment-seeking smokers who were randomly allocated 2 treatment conditions: cognitive behavioral treatment (CBT; n = 74), or CBT + CM (n = 73). CBT was applied in 1-hr group-based sessions over 6 weeks. The CM protocol was voucher-based with maximum earnings of €300 (US$339). Depressive symptoms were assessed using the Beck Depression Inventory-II. Smoking abstinence was verified though cotinine and carbon monoxide. Several analyses were conducted to explore the effect of treatment condition and baseline depressive symptoms on treatment outcomes, as well as the effect of treatment condition and smoking status on depressive symptoms. The CBT + CM condition was more effective than CBT, independent of depressive symptoms. The presence of depressive symptoms decreased the number of days of continuous smoking abstinence. Participants with a greater number of days of continuous smoking abstinence had fewer depressive symptoms than those with fewer days of continuous smoking abstinence. Findings suggest that health care providers should consider encouraging their patients with depressive symptoms to seek smoking cessation services that include both smoking cessation protocols and behavioral activation for mood management, thus maximizing both smoking and depressive outcomes.

    While much is known about the effect of smoke and vapors on the composition of blood, little is known about their impact on the composition of breath. When tobacco from traditional cigarettes (T) is burned, it produces harmful smoke compared with the vapor produced when using electronic cigarettes (E). Using a noninvasive, safe, and rapid CO2 laser-photoacoustic method, this study aimed to examine the ethylene changes at different time intervals in the exhaled breath composition of E-cigarette smokers and T-cigarette smokers, before and after the consecutive exposures to cigarettes. Oxidative stress from exposure to tobacco smoke has a role in the pathogenic process, leading to chronic obstructive pulmonary disease. The evidence on the mechanisms by which T-smoking causes damage indicates that there is no risk-free level of exposure to tobacco smoke. The study revealed that the ethylene level (in the E-cigarette smoker's case) was found to be in smaller concentrations (compared with T-cigarette smoker's case) and that E-cigarettes may provide an alternative to T-cigarette smoking.

    Tobacco use is the leading cause of preventable disease and death in the United States, resulting in more than 480,000 premature deaths and $289 billion in direct health care expenditures and productivity losses each year. Despite progress over the past several decades, millions of adults still smoke cigarettes, the most commonly used tobacco product in the United States. To assess progress made toward the Healthy People 2020 target of reducing the proportion of U.S. adults who smoke cigarettes to ≤12.0% (objective TU-1.1), CDC used data from the 2013 National Health Interview Survey (NHIS) to provide updated national estimates of cigarette smoking prevalence among adults aged ≥18 years. Additionally, for the first time, estimates of cigarette smoking prevalence were assessed among lesbian, gay, or bisexual persons (LGB) using NHIS data. The proportion of U.S. adults who smoke cigarettes declined from 20.9% in 2005 to 17.8% in 2013, and the proportion of daily smokers declined from 16.9% to 13.7%. Among daily cigarette smokers, the proportion who smoked 20-29 cigarettes per day (CPD) declined from 34.9% to 29.3%, and the proportion who smoked ≥30 CPD declined from 12.7% to 7.1%. However, cigarette smoking remains particularly high among certain groups, including adults who are male, younger, multiracial or American Indian/Alaska Native, have less education, live below the federal poverty level, live in the South or Midwest, have a disability/limitation, or who are LGB. Proven population-based interventions, including tobacco price increases, comprehensive smoke-free policies in worksites and public places, high-impact anti-tobacco mass media campaigns, and easy access to smoking cessation assistance, are critical to reducing cigarette smoking and smoking-related disease and death among U.S. adults, particularly among subpopulations with the greatest burden.

    A method for the rapid analysis of volatile organic compounds (VOCs) in smoke from tobacco and electronic cigarettes and in exhaled breath of users of these smoking systems has been developed. Both disposable and rechargeable e-cigarettes were considered. Smoke or breath were collected in Bio-VOCs. VOCs were then desorbed in Tenax cartridges which were subsequently analyzed by thermal desorption coupled to gas chromatography-mass spectrometry. The method provides consistent results when comparing the VOC compositions from cigarette smoke and the equivalent exhaled breath of the smokers. The differences in composition of these two sample types are useful to ascertain which compounds are retained in the respiratory system after tobacco cigarette or e-cigarette smoking. Strong differences were observed in the VOC composition of tobacco cigarette smoke and exhaled breath when comparing with those of e-cigarette smoking. The former involved transfers of a much larger burden of organic compounds into smokers, including benzene, toluene, naphthalene and other pollutants of general concern. e-Cigarettes led to strong absorptions of propylene glycol and glycerin in the users of these systems. Tobacco cigarettes were also those showing highest concentration differences between nicotine concentrations in smoke and exhaled breath. The results from disposable e-cigarettes were very similar to those from rechargeable e-cigarettes. PMID:26243705

    Behavioral economic demand curves, or quantitative representations of drug consumption across a range of prices, have been used to assess motivation for a variety of drugs. Such curves generate multiple measures of drug demand that are associated with cigarette consumption and nicotine dependence. However, little is known about the relationships among these facets of demand. The aim of the study was to quantify these relationships in adolescent smokers by using exploratory factor analysis to examine the underlying structure of the facets of nicotine incentive value generated from a demand curve measure. Participants were 138 adolescent smokers who completed a hypothetical cigarette purchase task, which assessed estimated cigarette consumption at escalating levels of price/cigarette. Demand curves and five facets of demand were generated from the measure: Elasticity (i.e., 1/α or proportionate price sensitivity); Intensity (i.e., consumption at zero price); O(max) (i.e., maximum financial expenditure on cigarettes); P(max) (i.e., price at which expenditure is maximized); and Breakpoint (i.e., the price that suppresses consumption to zero). Principal components analysis was used to examine the latent structure among the variables. The results revealed a two-factor solution, which were interpreted as "Persistence," reflecting insensitivity to escalating price, and "Amplitude," reflecting the absolute levels of consumption and price. These findings suggest a two factor structure of nicotine incentive value as measured via a demand curve. If supported, these findings have implications for understanding the relationships among individual demand indices in future behavioral economic studies and may further contribute to understanding of the nature of cigarette reinforcement.

    Tobacco use during later adolescence and young adulthood may cause serious neurophysiological changes; rationally, it is extremely important to study the relationship between brain dysfunction and behavioral performances in young adult smokers. Previous resting state studies investigated the neural mechanisms in smokers. Unfortunately, few studies focused on spontaneous activity differences between young adult smokers and nonsmokers from both intra-regional and inter-regional levels, less is known about the association between resting state abnormalities and behavioral deficits. Therefore, we used fractional amplitude of low frequency fluctuation (fALFF) and resting state functional connectivity (RSFC) to investigate the resting state spontaneous activity differences between young adult smokers and nonsmokers. A correlation analysis was carried out to assess the relationship between neuroimaging findings and clinical information (pack-years, cigarette dependence, age of onset and craving score) as well as cognitive control deficits measured by the Stroop task. Consistent with previous addiction findings, our results revealed the resting state abnormalities within frontostriatal circuits, i.e., enhanced spontaneous activity of the caudate and reduced functional strength between the caudate and anterior cingulate cortex (ACC) in young adult smokers. Moreover, the fALFF values of the caudate were correlated with craving and RSFC strength between the caudate and ACC was associated with the cognitive control impairments in young adult smokers. Our findings could lead to a better understanding of intrinsic functional architecture of baseline brain activity in young smokers by providing regional and brain circuit spontaneous neuronal activity properties as well as their association with cognitive control impairments.

    The aims of the study were to (1) describe how and why smokers start to vape and what products they use; (2) relate findings to the COM-B theory of behaviour change (three conditions are necessary for behaviour change (B): capability (C), opportunity (O), and motivation (M)); and (3) to consider implications for e-cigarette policy research. Semi-structured interviews (n = 30) were conducted in London, UK, with smokers or ex-smokers who were currently using or had used e-cigarettes. E-cigarette initiation (behaviour) was facilitated by: capability (physical capability to use an e-cigarette and psychological capability to understand that using e-cigarettes was less harmful than smoking); opportunity (physical opportunity to access e-cigarettes in shops, at a lower cost than cigarettes, and to vape in "smoke-free" environments, as well as social opportunity to vape with friends and family); and motivation (automatic motivation including curiosity, and reflective motivation, including self-conscious decision-making processes related to perceived health benefits). The application of the COM-B model identified multiple factors that may lead to e-cigarette initiation, including those that could be influenced by policy, such as price relative to cigarettes and use in smoke-free environments. The effects of these policies on initiation should be further investigated along with the possible moderating/mediating effects of social support. PMID:27376312

    Critical gaps exist in understanding the patterns and correlates of dual use of electronic cigarettes (ECs) and combustible cigarettes (CCs), particularly in ethnic minority populations. In this study, we assessed CC and EC use in the naturalistic environment using ecological momentary assessment (EMA). We hypothesized that within-subject variation in EC use (yes/no each day) would be inversely associated with within-subject variation in number of CCs consumed and craving during that same day. We also examined gender and nicotine dependence as moderators of the EC-CC and EC-craving covariations. Korean American emerging adult (KAEA; 18-25 years old) smokers (N = 78) completed 7 days of EMA. Participants completed EMA surveys throughout the day, which assessed CC craving, and end-of-day surveys, which assessed EC use and the number of CCs smoked that day. Generalized linear mixed models were used to predict day-level EC use, with number of CCs smoked and craving during that same day, gender, and nicotine dependence as predictors (n = 501). We found that within-subject variation in CC use was not associated with same-day EC use; neither was within-subject variation in craving (ps > .27). Gender moderated the relationship between craving and EC use on a given day (p = .03); only for females, on the days with higher craving, the likelihood of their EC use that day was significantly heightened. This study does not suggest that EC use is linked with lower CC smoking quantity, at least at the day level and among KAEA smokers. CC craving may play a role in dual EC-CC use for KAEA female smokers.

    Full Text Available In France, between 2000 and 2008, concurrently to the increase in cigarette price, we observed an increasing social differentiation of cigarette smoking: smoking prevalence decreased among executive managers and professional occupations, it remained stable among manual workers, and it increased among the unemployed. Poor smokers were heavier smokers, they were more frequently tobacco-dependent, and they were more prone to smoke automatically or to reduce “negative feelings”. In-depth interviews provided a more comprehensive insight into poor smokers’ motivations: they were aware of their addiction, but they also talked about the pleasure they get from smoking, and they highlighted the essential needs satisfied by smoking: stress relief, cheap leisure, compensation for loneliness, break-up or redundancy… Acknowledging the functional aspects of smoking experienced by poor smokers helps to understand why increasing the cigarette price is unlikely to deter many poor smokers from smoking.

    The present study explores different drivers of cigarette and water pipe smoking among middle and high school students in Isfahan province. A questionnaire-based cross-sectional study was conducted. Trained staff collected questionnaires and saliva samples for response accuracy evaluation. Prevalence by demographic, parental and educational factors was calculated. Logistic regression was applied to compare behavior drivers of those who purely smoked cigarettes or a waterpipe. Waterpipe smokers were considered as the reference category. This study reported ORs along 95% confidence intervals; 5408 questionnaires were returned. The sample age was 15.37±01.70 on average. The self-reported prevalence of cigarette and waterpipe experimentation was 11.60% (n=624) and 20.70% (n=1,109), respectively; and 5.08% (n=311), 11.06% (n=619) for smokers, and 13.30% (n=711) for the whole sample. Psychological factors were the most important driver for cigarette smoking; bad event happening with odds of 2.38 (95% CI: 1.29-4.39); angriness 2.58 times (95% CI: 1.51-4.43); and distress by 2.49 times (95% CI: 1.42-4.40). Habitual situations were strong predictors of cigarette smoking, but not a predictor of waterpipe smoking, such as smoking after a meal (OR=3.11, 95% CI: 1.67-5.77); and smoking after waking up (OR=2.56, 95% CI: 1.42-4.40). Comprehensive and multifaceted preventive programs must tailor identified factors and increase family's awareness. PMID:26231400

    Introduction Waterpipe tobacco smoking, also known as hookah and shisha, has surged in popularity among young people in the United States. Waterpipe is also increasingly becoming the first tobacco product that young people try. Given the limited access to and limited portability of waterpipes, waterpipe smokers who become more nicotine dependent over time may be more likely to turn to cigarettes. This study examined the relationship between waterpipe tobacco smoking and susceptibility to cigarette smoking among young adults in the United States. Methods Using data from the 2012–2013 National Adult Tobacco Survey, a nationally representative sample of US adults, we reported rates of current waterpipe smoking and susceptibility to cigarette smoking by demographic characteristics and by use of other tobacco products among survey participants aged 18 to 24 years. Multivariable logistic regression was used to examine the relationship between current waterpipe smoking and susceptibility to cigarette smoking, defined as the lack of a firm intention not to smoke soon or within the next year. Results Of 2,528 young adults who had never established cigarette smoking, 15.7% (n = 398) reported being waterpipe smokers (every day or some days [n = 97; 3.8%] or rarely [n = 301; 11.9%]); 44.2% (176/398) of waterpipe smokers reported being susceptible to cigarette smoking. Those who smoked waterpipe rarely were 2.3 times as susceptible to cigarette smoking as those who were not current waterpipe smokers (OR = 2.3; 95% CI, 1.6–3.4). Conclusion Current waterpipe smoking is associated with susceptibility to cigarette smoking among young adults in the United States. Longitudinal studies are needed to demonstrate causality between waterpipe smoking and initiation of cigarette smoking. PMID:26890407

    Further understanding is needed of the functionalities and efficiency of social media for health intervention research recruitment. Facebook was examined as a mechanism to recruit young adults for a smoking cessation intervention. An ad campaign targeting young adult smokers tested specific messaging based on market theory and successful strategies used to recruit smokers in previous clinical trials (i.e. informative, call to action, scarcity, social norms), previously successful ads, and general messaging. Images were selected to target smokers (e.g., lit cigarette), appeal to the target age, vary demographically, and vary graphically (cartoon, photo, logo). Facebook's Ads Manager was used over 7 weeks (6/10/13 - 7/29/13), targeted by age (18-25), location (U.S.), and language (English), and employed multiple ad types (newsfeed, standard, promoted posts, sponsored stories) and keywords. Ads linked to the online screening survey or study Facebook page. The 36 different ads generated 3,198,373 impressions, 5,895 unique clicks, at an overall cost of $2,024 ($0.34/click). Images of smoking and newsfeed ads had the greatest reach and clicks at the lowest cost. Of 5,895 unique clicks, 586 (10%) were study eligible and 230 (39%) consented. Advertising costs averaged $8.80 per eligible, consented participant. The final study sample (n=79) was largely Caucasian (77%) and male (69%), averaging 11 cigarettes/day (SD=8.3) and 2.7 years smoking (SD=0.7). Facebook is a useful, cost-effective recruitment source for young adult smokers. Ads posted via newsfeed posts were particularly successful, likely because they were viewable via mobile phone. Efforts to engage more ethnic minorities, young women, and smokers motivated to quit are needed. PMID:25045624

    2008-07-01

    Full Text Available IntroductionIn 2002, 16 focus groups with young adult smokers who used or had tried nontraditional tobacco products (e.g., bidis, shisha, herbal cigarettes, kreteks, cigars, herbal smokeless products were conducted in Dallas, Texas, and Chattanooga, Tennessee, to gain an understanding of the appeal of these products. MethodsIn each city, groups were segmented by race or ethnicity and by educational status. ResultsMany consistent themes emerged across the groups. Nontraditional tobacco use is not common among young adult smokers. Although some products such as Black & Mild and Swisher Sweets cigars are used frequently by some groups, other products such as shisha, kreteks, and herbal cigarettes are less well known and infrequently used. Among focus group participants, use of nontraditional tobacco products tends to occur in clubs, during social gatherings, or at times when cigarettes are unavailable. More college students than those who were not in college cited cost and inconvenience of purchasing nontraditional tobacco products as reasons for not using them. All focus group participants agreed that African Americans use cigars more than any other racial or ethnic group. ConclusionOverall, findings suggest that the reasons for trying nontraditional tobacco products did not differ by race or ethnicity. Family members and peers were mentioned as the source of nontraditional tobacco products when first used. Cost, convenience, taste, smell, and strength were given as reasons both for using these products and for discontinuing their use.

  4. Expiratory CT in cigarette smokers: correlation between areas of decreased lung attenuation, pulmonary function tests and smoking history

    International Nuclear Information System (INIS)

    The aim of this study was to determine the correlation between cigarette-smoke-related bronchial disease and air trapping as assessed by expiratory high-resolution CT (HRCT) scans. Thirty healthy subjects (11 non-smokers, 7 ex-smokers for > 2 years, 12 current smokers; age range 35-55 years) with a smoking history between 0 and 28.5 pack-years underwent pulmonary function tests (PFT) and HRCT in inspiration and expiration in supine and prone position. The extent of air trapping was scored in ventral and dorsal aspects of the upper, middle and lower lung portions. In 24 subjects (7 non-smokers, 7 ex-smokers, 10 current smokers) areas of focal air trapping were found, and were present significantly more often in dependent lung portions (p < 0.05) compared with non-dependent portions. No significant differences were found between apical and basal lung zones. Scores of focal air trapping were not significantly different between smokers and ex-smokers, but were significantly lower (p < 0.05) in non-smokers and showed a significant (p < 0.0005) correlation with pack-years. The degree of air trapping was also associated with several lung function tests, especially RV, DLCO, FRC, FEV1 and FEV1/VC. Air trapping is seen in smokers with normal PFT and correlates with the severity of the smoking history, independently of current smoking status. (orig.) (orig.)

    Xiaomeng Xu

    Full Text Available Self-expanding experiences like falling in love or engaging in novel, exciting and interesting activities activate the same brain reward mechanism (mesolimbic dopamine pathway that reinforces drug use and abuse, including tobacco smoking. This suggests the possibility that reward from smoking is substitutable by self-expansion (through competition with the same neural system, potentially aiding cessation efforts. Using a model of self-expansion in the context of romantic love, the present fMRI experiment examined whether, among nicotine-deprived smokers, relationship self-expansion is associated with deactivation of cigarette cue-reactivity regions. Results indicated that among participants who were experiencing moderate levels of craving, cigarette cue-reactivity regions (e.g., cuneus and posterior cingulate cortex showed significantly less activation during self-expansion conditions compared with control conditions. These results provide evidence that rewards from one domain (self-expansion can act as a substitute for reward from another domain (nicotine to attenuate cigarette cue reactivity.

    Full Text Available Background Cigarette smoking is an important cause of mortality across the world, resulting in death of nearly six million people. Nearly 40% of the deaths are caused by cardiovascular disease and 20% are due to lung cancer. Cigarette smoking is said to increase the susceptibility towards vascular injuries by impacting phases of atherosclerosis, and altering blood pressure (BP, heart rate (HR and elevating plasma catecholamine levels. The objective of this study was to assess if cigarette smoking increases the rate pressure product (RPP at rest and after standing in young adult light smokers compared to non-smokers. Methods 30 young adult smokers and 30 non-smokers (19 - 24 years were enrolled in this case control study. The smoking pack-years was calculated. Blood pressure (BP was measured and RPP was calculated. The mean values between both groups were compared using the univariate analysis of variance adjusted for confounding variables. Results The smoking pack-years was 1.6±1.0 (0.2-4.5. RPP in smokers was 88.8±8.0, 96.2±10.2 at rest and after standing respectively. RPP in non-smokers at rest was 81.6±8.1 and 89.5±10.3 after standing. RPP was statistically significant in between both groups at rest. Conclusion Smoking increases the RPP significantly in young adult light smokers due to an increased HR when compared to non-smokers, at rest. This study reinforces that young adults who are light smokers have an increased workload on the heart, which affects their cardiac performance.

  8. Young adult smokers' perceptions of illicit tobacco and the possible impact of plain packaging on purchase behaviour.

    2012-04-01

    Plain (unbranded) packaging for cigarettes is at the top of the tobacco control agenda in both Australia and Europe. The evidence suggests that it will benefit public health by decreasing the appeal of tobacco products and increasing the power of the health warning. The tobacco industry instead argues that plain packaging would make it easier to counterfeit cigarettes, which would both confuse consumers and reduce price; thereby increasing consumption. Using focus group research we examined young adult smokers (N = 54) perceptions of, and ability to recognize, illicit tobacco and the possible impact of plain packaging on illicit tobacco purchasing behaviour. We found that the pack has no impact on the decision to buy illicit tobacco. Smokers were easily able to identify counterfeit cigarettes, not least by the pack, and buy it knowingly and in the full expectation that it will be inferior in quality. Illicit tobacco purchase, including that for counterfeit tobacco, was instead driven by availability and price. Given the extremely low manufacturing cost, per pack, of certain types of illicit cigarettes, it is difficult to envisage how plain packaging would alter the price of illicit tobacco in any meaningful way. The findings therefore suggest that a move to plain packaging would have no impact on young adult smokers' purchase behaviour. PMID:21441554

    Full Text Available To examine the impact of low-intensity continuous training program on antioxidant defense capability and lipid profile in male cigarette or hookah smokers. Forty-three male adults participated in a 12-week continuous training program at an intensity of 40% of VO2max. All subjects were subjected to anthropometric, physical and biochemical tests before and after the training program. The increase of Glutathione reductase (GR and Superoxide dismutase (SOD is significant only for cigarette smokers (CS and hookah smokers (HS groups. The Malondialdehyde (MDA decrease and α-tocopherol increase are significant only for HS group. GPx was increased in NS, CS and HS by 2.6% (p< 0.01, 2% (p< 0.05 and 1.7% (p< 0.05 respectively. Likewise, significant improvements of high-density lipoprotein cholesterol (HDL-C, low-density lipoprotein cholesterol (LDL-C and TC/HDL-C ratio were observed in three groups. En contrast no significant changes were recorded in triglycerides (TG. Also, significant reduction of total cholesterol (TC for CS group (p< 0.01 and HS groups (p< 0.05. This continuous training program appears to have an important role in lipid levels improving and oxidative stress attenuation.

    2010-06-01

    The present investigation sought to evaluate the unique explanatory relevance of pain-related anxiety in relation to negative and positive reinforcement smoking outcome expectancies among 135 (40.7% female; M(age) = 26.11, SD = 11.23) adult daily cigarette smokers. As predicted, pain-related anxiety was significantly related to greater expectancies that smoking will decrease negative affect, and lesser expectancies that smoking will result in positive outcomes. The observed effects were evident above and beyond the variance accounted for by gender, current level of non-specific bodily pain, daily cigarette use, relations with non-criterion outcome expectancies, and shared variance with anxiety sensitivity. Results suggest that there may be segments of the smoking population who are at relatively greater risk for certain expectancies for tobacco smoking by virtue of individual differences in pain-related anxiety.

    Full Text Available Abstract Background Chronic smoking is the main risk factor for chronic obstructive pulmonary disease. Knowledge on the response to the initial smoke exposures might enhance the understanding of changes due to chronic smoking, since repetitive acute smoke effects may cumulate and lead to irreversible lung damage. Methods We investigated acute effects of smoking on inflammation in 16 healthy intermittent smokers in an open randomised cross-over study. We compared effects of smoking of two cigarettes on inflammatory markers in exhaled air, induced sputum, blood and urine at 0, 1, 3, 6, 12, 24, 48, 96 and 192 hours and outcomes without smoking. All sputum and blood parameters were log transformed and analysed using a linear mixed effect model. Results Significant findings were: Smoking increased exhaled carbon monoxide between 0 and 1 hour, and induced a greater decrease in blood eosinophils and sputum lymphocytes between 0 and 3 hours compared to non-smoking. Compared to non-smoking, smoking induced a greater interleukin-8 release from stimulated blood cells between 0 and 3 hours, and a greater increase in sputum lymphocytes and neutrophils between 3 and 12 hours. Conclusion We conclude that besides an increase in inflammation, as known from chronic smoking, there is also a suppressive effect of smoking two cigarettes on particular inflammatory parameters.

    Between 2008 and 2013, Brazil experienced a large decline in smoking prevalence, with an innovative round of aversive pictorial health warnings implemented on cigarette packs and at points of sale in 2009. The objective of this study was to examine changes over time in the distribution of quitting attempts and self-reported thoughts about quitting due to health warnings among current smokers. We conducted a pre-post study to evaluate data from two nationally-representative surveys conducted in 2008 and 2013. Responses to questions on smokers' quitting attempts in the last year (yes vs. no) and whether health warnings led them to think about quitting in the last month (yes vs. no) were combined into four categories, for which the distribution of the Brazilian smoking population by year was estimated. A multinomial model was used to obtain proportions for each category, adjusted by socio-demographic variables and nicotine dependence. The proportion of smokers who reported making a quitting attempt in the last year and stated that health warnings led them think about quitting smoking statistically increased over time (from 30.0% to 33.1%; p-value=0.010). The percentage of those who answered "no" to these two questions also increased over time (from 23.5% to 32.9%; p-value≤0.001). These findings suggest that innovative warnings introduced in Brazil likely served as a "reminder" for continuing to think about cessation among those who attempted to quit in the last year. These warnings may have also triggered more avoidance of thinking about their contents than the previous warnings, which some studies have found to promote subsequent quitting activity.

    2016-01-01

    Background Identifying novel ways to recruit smokers for treatment studies is important. In particular, certain subgroups of adult smokers, such as heavy-drinking smokers, are at increased risk for serious medical problems and are less likely to try quitting smoking, so drawing this hard-to-reach population into treatment is important for improving health outcomes. Objective This study examined the utility of Facebook advertisements to recruit smokers and heavy-drinking smokers for treatment research and evaluated smoking and alcohol use and current treatment goals among those who responded to the Web-based survey. Methods Using Facebook’s advertising program, 3 separate advertisements ran for 2 months targeting smokers who were thinking about quitting. Advertisements were shown to adult (at least 18 years of age), English-speaking Facebook users in the greater New Haven, Connecticut, area. Participants were invited to complete a Web-based survey to determine initial eligibility for a smoking cessation research study. Results Advertisements generated 1781 clicks and 272 valid, completed surveys in 2 months, with one advertisement generating the most interest. Facebook advertising was highly cost-effective, averaging $0.27 per click, $1.76 per completed survey, and $4.37 per participant meeting initial screening eligibility. On average, those who completed the Web-based survey were 36.8 (SD 10.4) years old, and 65.8% (179/272) were female. Advertisements were successful in reaching smokers; all respondents reported daily smoking (mean 16.2 [SD 7.0] cigarettes per day). The majority of smokers (254/272, 93.4%) were interested in changing their smoking behavior immediately. Many smokers (161/272, 59.2%) also reported heavy alcohol consumption at least once a month. Among smokers interested in reducing their alcohol use, more were heavy drinkers (45/56, 80.4%) compared to non-heavy drinkers (11/56, 19.6%; χ2[1,N=272]=13.0, Padvertisements designed to target smokers

    Full Text Available Smoking-related diseases can be attributed to the inhalation of many different toxins, including heavy metals, which have a host of detrimental health effects. The current study reports the levels of arsenic (As, cadmium (Cd, chromium (Cr, nickel (Ni, and lead (Pb in cigarettes obtained from adult smokers participating in the 2009 wave of the ITC United States Survey (N = 320. The mean As, Cd, Cr, Ni, and Pb levels were 0.17, 0.86, 2.35, 2.21, and 0.44 µg/g, respectively. There were some differences in metal concentrations of cigarette brands produced by different manufacturers, suggesting differences in the source of tobaccos used by different companies. For Ni, there were significant pairwise differences between Philip Morris U.S. (PMUSA and R.J. Reynolds (RJR brands (PMUSA higher; p < 0.001, PMUSA and other manufacturer (OM brands (PMUSA higher; p < 0.001, and RJR and OM brands (RJR higher; p = 0.006. For Cr, RJR brands had higher levels than did OM brands (p = 0.02. Levels of As, Cd, and Pb did not differ significantly across manufacturer groups (p > 0.10. Because of the variety of toxic heavy metals in cigarette tobacco, and their numerous negative health effects, metal content in cigarette tobacco should be reduced.

    Background Warning labels on cigarette packages are an important venue for information about the hazards of smoking. The 2009 US Family Smoking Prevention and Tobacco Control Act mandated replacing the current text-only labels with graphic warning labels. However, labels proposed by the Food and Drug Administration (FDA) were challenged in court by the tobacco companies, who argued successfully that the proposed labels needlessly encroached on their right to free speech, in part because they included images of high emotional salience that indiscriminately frightened rather than informed consumers. Methods We used functional MRI to examine the effects of graphic warning labels' emotional salience on smokers' brain activity and cognition. Twenty-four smokers viewed a random sequence of blocks of graphic warning labels that have been rated high or low on an ‘emotional reaction’ scale in previous research. Results We found that labels rated high on emotional reaction were better remembered, associated with reduction in the urge to smoke, and produced greater brain response in the amygdala, hippocampi, inferior frontal gyri and the insulae. Conclusions Recognition memory and craving are, respectively, correlates of effectiveness of addiction related public health communications and interventions, and amygdala activation facilitates the encoding of emotional memories. Thus, our results suggest that emotional reaction to graphic warning labels contributes to their public health impact and may be an integral part of the neural mechanisms underlying their effectiveness. Given the urgency of the debate about the constitutional risks and public health benefits of graphic warning labels, these preliminary findings warrant consideration while longitudinal clinical studies are underway PMID:25564288

  18. Effects of Smoking Abstinence on Cigarette Craving, Nicotine Withdrawal, and Nicotine Reinforcement in Smokers With and Without Schizophrenia

    Science.gov (United States)

    2014-01-01

    Introduction: Schizophrenia is associated with a high prevalence of cigarette smoking. The aims of this study were to compare smokers with schizophrenia (SS) and control smokers without psychiatric illness (CS) on (a) cigarette craving and nicotine withdrawal symptom severity during a 72-hr smoking abstinence period; (b) nicotine reinforcement, before and after abstinence; and (c) latency to smoking lapse following abstinence. We also explored mediators of smoking lapse in SS and CS. Methods: SS (n = 28) and CS (n = 27) underwent a nicotine versus denicotinized cigarette puff choice task before and after a 72-hr period of smoking abstinence that was experimentally controlled by providing cash reinforcement contingent on biochemical verification of abstinence. Twenty-four hours after the second choice task, participants could receive a low-value reinforcer if they had continued to abstain since the previous day. Those who remained abstinent were recontacted a week later to determine time of their smoking lapse. Results: SS reported more severe cigarette craving and nicotine withdrawal symptoms throughout the 72-hr abstinence period, had greater nicotine preference after abstinence, and lapsed back to smoking significantly sooner than CS. The relationship between group and smoking lapse latency was mediated by baseline depression and nicotine withdrawal symptom severity but not by effects of abstinence on craving or nicotine reinforcement. Conclusions: Overall, these results indicate that negative affect is a key contributor to poor smoking cessation outcomes among those with schizophrenia. PMID:24113929

    2015-04-01

    This study investigated the relationship between lay theories of cigarette smoking and expectations to smoke. An incremental lay theory of smoking entails the belief that smoking behavior can change; an entity theory entails the belief that smoking behavior cannot change. Undergraduate nonsmokers and smokers completed a survey that assessed lay theories of smoking and smoking expectations. Results demonstrated that lay theories of smoking were differentially associated with smoking expectations for nonsmokers and smokers: stronger incremental beliefs were associated with greater expectations of trying smoking for nonsmokers but lower expectations of becoming a regular smoker for smokers. Implications for interventions are discussed.

  2. Systematic review of the epidemiological evidence comparing lung cancer risk in smokers of mentholated and unmentholated cigarettes

    Full Text Available Abstract Background US mentholated cigarette sales have increased considerably over 50 years. Preference for mentholated cigarettes is markedly higher in Black people. While menthol itself is not genotoxic or carcinogenic, its acute respiratory effects might affect inhalation of cigarette smoke. This possibility seems consistent with the higher lung cancer risk in Black men, despite Black people smoking less and starting smoking later than White people. Despite experimental data suggesting similar carcinogenicity of mentholated and non-mentholated cigarettes, the lack of convincing evidence that mentholation increases puffing, inhalation or smoke uptake, and the similarity of lung cancer rates in Black and White females, a review of cigarette mentholation and lung cancer is timely given current regulatory interest in the topic. Methods Epidemiological studies comparing lung cancer risk in mentholated and non-mentholated cigarette smokers were identified from MedLine and other sources. Study details were extracted and strengths and weaknesses assessed. Relative risk estimates were extracted, or derived, for ever mentholated use and for long-term use, overall and by gender, race, and current/ever smoking, and meta-analyses conducted. Results Eight generally good quality studies were identified, with valid cases and controls, and appropriate adjustment for age, gender, race and smoking. The studies afforded good power to detect possible effects. However, only one study presented results by histological type, none adjusted for occupation or diet, and some provided no results by length of mentholated cigarette use. The data do not suggest any effect of mentholation on lung cancer risk. Adjusted relative risk estimates for ever use vary from 0.81 to 1.12, giving a combined estimate of 0.93 (95% confidence interval 0.84-1.02, n = 8, with no increase in males (1.01, 0.84-1.22, n = 5, females (0.80, 0.67-0.95, n = 5, White people (0.87, 0.75-1.03, n = 4

    Young adults are at risk for initiation of tobacco use and progression to tobacco dependence. Not every person who smokes cigarettes becomes tobacco dependent, however, and non-daily smoking is becoming more prevalent among those who use tobacco. It is likely that individual differences in psychosocial and behavioral factors influence risk for engaging in non-daily and daily cigarette smoking. The objective of this study was to investigate the associations between impulsivity and smoking status in young adults who vary in frequency of cigarette smoking. Young adult first-year college students between the ages of 18-24 (512) were classified to one of three groups: non-smokers, non-daily smokers, or daily smokers, and impulsivity was assessed using the UPPS-P (negative and positive urgency, lack of premeditation, lack of perseverance, sensation seeking). When all impulsivity dimensions were used simultaneously to predict smoking status, negative urgency predicted increased risk of membership in the daily smoking group and lack of premeditation predicted increased risk of membership in the non-daily smoking group. These results suggest that dimensions of impulsivity may contribute differentially to forms of smoking behavior in young adults.

    In 2013, it was estimated that the prevalence of cigarette smoking among American Indians was 36.5%, the highest of all racial/ethnic groups in the continental United States (1). Among American Indians, considerable cultural and geographic variation in cigarette smoking exists. Smoking prevalence among American Indians is lowest in the Southwest and highest in the Upper Midwest/Northern Plains (2). Little information is available about tobacco use among urban American Indians, who might not have ever lived on a reservation or be enrolled in or affiliated with a tribe. In Minnesota, a significant proportion of American Indians reside in urban areas. Among Minnesota's residents who identify as American Indian alone or in combination with another race, 30% live in Hennepin County and Ramsey County, which encompass Minneapolis and St. Paul, respectively (collectively known as the Twin Cities). The predominant tribes (Ojibwe [Chippewa] and Dakota/Lakota/Nakota [Sioux]) traditionally have used locally grown tobacco (Nicotiana rustica), red willow, and other plants for religious ceremonies, although nonceremonial tobacco is often substituted for traditional plants. To assess prevalence of cigarette smoking among this population, it is important to distinguish ceremonial tobacco use (smoked or used in other ways) from nonceremonial tobacco use. To obtain estimates of cigarette smoking prevalence among American Indians in Hennepin and Ramsey counties, the American Indian Adult Tobacco Survey was administered to 964 American Indian residents in 2011, using respondent-driven sampling. Among all participants, 59% were current smokers, 19% were former smokers, and 22% had never smoked. Approximately 40% of employed participants reported that someone smoked in their workplace area during the preceding week. High prevalences of cigarette smoking and secondhand smoke exposure among urban American Indians in Minnesota underscores the need for a comprehensive and culturally

    Full Text Available Abstract Background Various factors affect tooth loss in older age including cigarette smoking; however, evidence regarding the association between smoking and tooth loss during young adulthood is limited. The present study examined the association between cigarette smoking and tooth loss experience among adults aged 20–39 years using linked data from two national databases in Japan. Methods Two databases of the National Nutrition Survey (NNS and the Survey of Dental Diseases (SDD, which were conducted in 1999, were obtained from the Ministry of Health, Labor and Welfare with permission for analytical use. In the NNS, participants received physical examinations and were interviewed regarding dietary intake and health practices including cigarette smoking, whereas in the SDD, participants were asked about their frequency of daily brushing, and received oral examinations by certified dentists. Among 6,805 records electronically linked via household identification code, 1314 records of individuals aged 20 to 39 years were analyzed. The prevalence of 1+ tooth loss was compared among non-, former, and current smokers. Multiple logistic regression models were constructed including confounders: frequency of tooth brushing, body mass index, alcohol consumption, and intake of vitamins C and E. Results Smoking rates differed greatly in men (53.3% and women (15.5%. The overall prevalence of tooth loss was 31.4% (31.8% men and 31.1% women. Tooth loss occurred more frequently among current smokers (40.6% than former (23.1% and non-smokers (27.9%. Current smoking showed a significant association with 1+ tooth loss in men (adjusted OR = 2.21 [1.40–3.50], P = 0.0007 and women (1.70 [1.13–2.55], P = 0.0111.

    Bacterial growth from a single flake of tobacco was documented for cigarettes that had been purchased recently from local vendors and from cigarettes that had been stored for more than six years in a warehouse. In a novel tobacco flake assay, a pack of cigarettes was opened within the sterile environment of a laminar flow hood. A single flake of tobacco was collected randomly and aseptically from the middle of the cigarette column and placed onto the surface of a blood agar plate. The test cigarettes included eight different popular US brands, and these were from three different tobacco companies. After 24 hours of incubation at 37 degrees C, the plates showed bacterial growth for tobacco from all brands of cigarettes. Further, more than 90% of the individual tobacco flakes of a given brand grew bacteria. Likewise, bacteria grew from microparticulate tobacco that had been sieved from cigarettes. Tobacco flakes were observed lying loosely on the cut surface of the filter of cigarettes in newly opened packs, and bacteria grew from cigarette filters that had been touched to the surface of a blood agar plate. In conclusion, the results of these studies predict that diverse microbes and microbial toxins are carried by tobacco microparticulates that are released from the cigarette during smoking, and carried into mainstream smoke that is sucked deep into the lung.

    Full Text Available Time to first cigarette (TTFC after waking is an indicator of nicotine dependence. The association between TTFC and chronic obstructive pulmonary disease (COPD, the third leading cause of death in the United States, has not yet been reported.We investigated the cross-sectional association between TTFC and prevalent COPD among 6,108 current smokers in the Prostate, Lung, Colorectal, and Ovarian (PLCO Cancer Screening Trial. COPD was defined as a self-reported diagnosis of emphysema, chronic bronchitis, or both. Current smokers in PLCO reported TTFC, the amount of time they typically waited before smoking their first cigarette of the day after waking, in four categories: ≤ 5, 6-30, 31-60, or > 60 minutes. We used logistic regression models to investigate the association between TTFC and prevalent COPD with adjustments for age, gender, race, education, and smoking (cigarettes/day, years smoked during lifetime, pack-years, age at smoking initiation, and prior lung cancer diagnosis.COPD was reported by 19% of these 6,108 smokers. Individuals with the shortest TTFC had the greatest risk of COPD; compared to those with the longest TTFC (> 60 minutes the adjusted odds ratios (OR and 95% confidence intervals (CI for COPD were 1.48 (95% CI, 1.15-1.91, 1.64 (95% CI, 1.29-2.08, 2.18 (95% CI, 1.65-2.87 for those with TTFC 31-60 minutes, 6-30 minutes, and ≤ 5 minutes, respectively (P-trend 60 minutes, the adjusted OR (95% CI was 2.29 (1.69-3.12 for emphysema and 2.99 (1.95-4.59 for chronic bronchitis.Current smokers with shorter TTFC have increased risk of COPD compared to those with longer TTFC, even after comprehensive adjustment for established smoking covariates. Future epidemiologic studies, including prospective designs, should incorporate TTFC to better assess disease risk and evaluate the potential utility of TTFC as a COPD screening tool for smokers in the clinical setting.

    Full Text Available Chronic obstructive pulmonary disease (COPD is often associated with age-related systemic abnormalities that adversely affect the prognosis. Whether these manifestations are linked to the lung alterations or are independent complications of smoking remains unclear.To look for aging-related systemic manifestations and telomere shortening in COPD patients and smokers with minor lung destruction responsible for a decline in the diffusing capacity for carbon monoxide (DLCO corrected for alveolar volume (KCO.Cross-sectional study in 301 individuals (100 with COPD, 100 smokers without COPD, and 101 nonsmokers without COPD.Compared to control smokers, patients with COPD had higher aortic pulse-wave velocity (PWV, lower bone mineral density (BMD and appendicular skeletal muscle mass index (ASMMI, and shorter telomere length (TL. Insulin resistance (HOMA-IR and glomerular filtration rate (GFR were similar between control smokers and COPD patients. Smokers did not differ from nonsmokers for any of these parameters. However, smokers with normal spirometry but low KCO had lower ASMMI values compared to those with normal KCO. Moreover, female smokers with low KCO, had lower BMD and shorter TL compared to those with normal KCO.Aging-related abnormalities in patients with COPD are also found in smokers with minor lung dysfunction manifesting as a KCO decrease. Decreased KCO might be useful, particularly among women, for identifying smokers at high risk for aging-related systemic manifestations and telomere shortening.

    The assessment of temporal differences in cigarette consumption may help in understanding whether a smoking population is becoming more resistant to quitting over time. We calculated absolute differences in average cigarette consumption, stratified by birth cohort and age group. Data were obtained from random samples from two Brazilian national household surveys (1989, N = 12,782; 2008, N = 6,675). A linear regression model was used to adjust estimates by gender, educational level, and place of residence. Birth cohort analysis found that average daily cigarette consumption increased for individuals born after 1964 and decreased for those born before 1955 (adjusted p-values consumption between 1989 and 2008 (adjusted p-values Brazil's anti-tobacco policy changes and rapid economic growth may be principally related to temporal changes in cigarette consumption for most age groups, rather than to a change in the relationship between age and cigarette consumption.

    Full Text Available Cigarette smoking is an important risk factor for hypertension. However, the effects on hypertension of the interaction between smoking and the genotype of the nicotinic acetylcholine receptor gene are unclear. The purpose of this study is to determine whether the CHRNA3 rs6495308 genotype affects the association between daily cigarette consumption and hypertension. We recruited 947 male smokers in southern China and used a questionnaire administered in face to face interviews to obtain information on their socio-demographic characteristics and smoking behavior. Blood samples were collected to test for CHRNA3 rs6495308 genotype variations. Three blood-pressure measurements were taken for each participant, and the average values recorded. We found that, compared with light smoking (<15 cigarettes per day, heavy smoking (≥15 cigarettes per day yielded a greater risk of hypertension. We also observed that the interaction between daily cigarette consumption and the CHRNA3 rs6495308 genotype may affect hypertension. Heavy smokers with the homozygous mutant CHRNA3 rs6495308 genotype exhibited a significantly greater risk of hypertension than light smokers with wild-type CHRNA3 rs6495308 genotypes. The positive interaction between heavy smoking and the homozygous mutant CHRNA3 rs6495308 genotype was found to affect the likelihood of hypertension in Chinese male smokers.

    This study used five waves of the Chinese Longitudinal Healthy Longevity Survey to examine the relationship between living arrangements, smoking, and drinking among older adults in China from 1998-2008. We found that living arrangements had strong implications for cigarette smoking and alcohol consumption among the elderly. First, the likelihood of smoking was lower among older men living with children, and older women living either with a spouse, or with both a spouse and children; and the likelihood of drinking was lower among both older men, and women living with both a spouse and children, compared with those living alone. Second, among dual consumers (i.e., being a drinker and a smoker), the amount of alcohol consumption was lower among male dual consumers living with children, while the number of cigarettes smoked was higher among female dual consumers living with others, compared with those living alone. Third, among non-smoking drinkers, the alcohol consumption was lower among non-smoking male drinkers in all types of co-residential arrangements (i.e., living with a spouse, living with children, living with both a spouse and children, or living with others), and non-smoking female drinkers living with others, compared with those living alone. Results highlighted the importance of living arrangements to cigarette smoking and alcohol consumption among Chinese elderly. Co-residential arrangements provided constraints on Chinese older adults' health-risk behaviors, and had differential effects for men and women.

    Increasing evidence indicates that cigarette smoking is a strong predictor of electronic cigarettes (e-cigarettes) use, particularly in adolescents, yet the effects has not be systematically reviewed and quantified. Relevant studies were retrieved by searching three databases up to June 2015. The meta-analysis results were presented as pooled odds ratios (ORs) with 95% confidence intervals (CIs) calculated by a random-effects model. Current smokers were more likely to use e-cigarette currently (OR: 14.89, 95% CI: 7.70-28.78) and the probability was greater in adolescents than in adults (39.13 vs. 7.51). The probability of ever e-cigarettes use was significantly increased in smokers (OR: 14.67, 95% CI: 11.04-19.49). Compared with ever smokers and adults, the probabilities were much greater in current smokers (16.10 vs. 9.47) and adolescents (15.19 vs. 14.30), respectively. Cigarette smoking increases the probability of e-cigarettes use, especially in current smokers and adolescents.

  15. Effect of Smoking Abstinence and Reduction in Asthmatic Smokers Switching to Electronic Cigarettes: Evidence for Harm Reversal

    Full Text Available Electronic cigarettes (e-cigs are marketed as safer alternatives to tobacco cigarettes and have shown to reduce their consumption. Here we report for the first time the effects of e-cigs on subjective and objective asthma parameters as well as tolerability in asthmatic smokers who quit or reduced their tobacco consumption by switching to these products. We retrospectively reviewed changes in spirometry data, airway hyper-responsiveness (AHR, asthma exacerbations and subjective asthma control in smoking asthmatics who switched to regular e-cig use. Measurements were taken prior to switching (baseline and at two consecutive visits (Follow-up/1 at 6 (±1 and Follow-up/2 at 12 (±2 months. Eighteen smoking asthmatics (10 single users, eight dual users were identified. Overall there were significant improvements in spirometry data, asthma control and AHR. These positive outcomes were noted in single and dual users. Reduction in exacerbation rates was reported, but was not significant. No severe adverse events were noted. This small retrospective study indicates that regular use of e-cigs to substitute smoking is associated with objective and subjective improvements in asthma outcomes. Considering that e-cig use is reportedly less harmful than conventional smoking and can lead to reduced cigarette consumption with subsequent improvements in asthma outcomes, this study shows that e-cigs can be a valid option for asthmatic patients who cannot quit smoking by other methods.

    Few studies have examined how diverse populations interpret warning labels. This study examined interpretations of 9 graphic cigarette warning labels (image plus text) proposed by the U.S. Food and Drug Administration among a convenience sample of youth (ages 13-17) and adults (18+) across the United States. Participants (N = 1,571) completed a cross-sectional survey. Participants were asked to select 1 of 3 plausible interpretations (1 preferred vs. 2 alternative) created by the research team about the particular consequence of smoking addressed in each warning label. Participants also rated each label for novelty, counterarguing, perceived effectiveness, and harm. Smokers reported their thoughts of quitting, self-efficacy, and motivation to quit. Although at least 70% of the sample chose the preferred interpretation for 7 of 9 labels, only 13% of participants chose all 9 preferred interpretations. The odds of selecting the preferred interpretation were lower among African Americans, among those with less education, and for labels perceived as being more novel. Smokers reported greater counterarguing and less perceived effectiveness and harms than nonsmokers, but results were not consistent across all labels and interpretations. The alternative interpretations of cigarette warning labels were associated with lower perceived effectiveness and lower perceived harms of smoking, both of which are important for motivating quit attempts.

Third, among non-smoking drinkers, the alcohol consumption was lower among non-smoking male drinkers in all types of co-residential arrangements (i.e., living with a spouse, living with children, living with both a spouse and children, or living with others, and non-smoking female drinkers living with others, compared with those living alone. Results highlighted the importance of living arrangements to cigarette smoking and alcohol consumption among Chinese elderly. Co-residential arrangements provided constraints on Chinese older adults’ health-risk behaviors, and had differential effects for men and women.

    Cigarette smoking and the use of smokeless tobacco both cause substantial morbidity and premature mortality. The concurrent use of these products might increase dependence and the risk for tobacco-related disease and death. State-specific estimates of prevalence and relative percent change in current cigarette smoking, smokeless tobacco use, and concurrent cigarette smoking and smokeless tobacco use among U.S. adults during 2011-2013, developed using data from the Behavioral Risk Factor Surveillance System (BRFSS), indicate statistically significant (padvertising and promotion, controlling access to tobacco products, and promoting cessation assistance for smokers to quit, as well as continuing and implementing mass media campaigns that contain graphic anti-smoking ads, such as the Tips from Former Smokers (TIPS) campaign.

    Smoking is one of the most prevalent dependence disorders. Previous studies have detected structural and functional deficits in smokers. However, few studies focused on the changes of resting state functional connectivity (RSFC) of the brain regions with structural deficits in young adult smokers. Twenty-six young adult smokers and 26 well-matched healthy non-smokers participated in our study. Voxel-based morphometry (VBM) and RSFC were employed to investigate the structural and functional changes in young adult smokers. Compared with healthy non-smokers, young smokers showed increased gray matter (GM) volume in the left putamen and decreased GM volume in the left anterior cingulate cortex (ACC). Moreover, GM volume in the left ACC has a negative correlation trend with pack-years and GM volume in the left putamen was positively correlated with pack-years. The left ACC and putamen with abnormal volumes were chosen as the regions of interest (ROIs) for the RSFC analysis. We found that smokers showed increased RSFC between the left ACC and right amygdala and between the left putamen and right anterior insula. We revealed structural and functional deficits within the frontostriatal circuits in young smokers, which may shed new insights into the neural mechanisms of smoking.

    Full Text Available This study uses longitudinal data from the International Tobacco Control Southeast Asia (ITC-SEA Thailand survey to explore patterns and predictors of successful quitting among Thai adult smokers as a function of time quit. A cohort of a representative sample of 2000 smokers was surveyed four times from 2005 to 2009. A sample of 1533 individuals provided data for at least one of the reported analyses. Over the four years of follow-up, 97% made attempts to quit. Outcomes were successful quitting/relapse: (a quit attempts of at least one month (short-term relapse, 43% (57% remaining quit; (b surviving at least six months (medium-term (31%; (c relapse between one and six months (45%; (d having continuously quit between Waves 3 and 4 (sustained abstinence (14%; and (e relapse from six months on (44% compared to those who continuously quit between Waves 3 and 4 (56%. Predictors for early relapse (<1 month differ from longer-term relapse. Age was associated with reduced relapse over all three periods, and was much stronger for longer periods of abstinence. Cigarette consumption predicted relapse for short and medium terms. Self-assessed addiction was predictive of early relapse, but reversed to predict abstinence beyond six months. Previous quit history of more than one week was predictive of early abstinence, but became unrelated subsequently. Self-efficacy was strongly predictive of abstinence in the first month but was associated with relapse thereafter. Some determinants of relapse change with time quit, but this may be in somewhat different to patterns found in the West.

    The prevalence of e-cigarette use is increasing, yet few studies have focused on its use in racial/ethnic minority populations. We examined associations between race/ethnicity and e-cigarette use, plans to continue using e-cigarettes, and reasons for use among current/former smokers. Participants (285 in total; 29% non-Hispanic White, 42% African American/Black, and 29% Hispanic) were recruited between June and November 2014. Telephone-administered surveys assessed demographics, cigarette smoking, e-cigarette use, plans to continue using, and reasons for use. Analyses of covariance (ANCOVAs) and multivariable logistic regressions were conducted. African Americans/Blacks were significantly less likely to report ever-use compared to Whites and Hispanics (50% vs. 71% and 71%, respectively; p e-cigarettes compared to Whites and Hispanics (72% vs. 53% and 47%, respectively, p = 0.01). African American/Black participants were more likely to use e-cigarettes as a cessation aid compared to both Whites (p = 0.03) and Hispanics (p = 0.48). White participants were more likely to use e-cigarettes to save money compared to Hispanics (p = 0.02). In conclusion, racial/ethnic differences in e-cigarette use, intentions, and reasons for use emerged in our study. African American ever users may be particularly vulnerable to maintaining their use, particularly to try to quit smoking. These findings have implications for cigarette smoking and e-cigarette dual use, continued e-cigarette use, and potentially for smoking-related disparities. PMID:27754449

    Background Identifying novel ways to recruit smokers for treatment studies is important. In particular, certain subgroups of adult smokers, such as heavy-drinking smokers, are at increased risk for serious medical problems and are less likely to try quitting smoking, so drawing this hard-to-reach population into treatment is important for improving health outcomes.

    The present investigation examined the extent to which panic reactivity to bodily sensations is related to distress tolerance (DT) among daily smokers. It was hypothesized that panic reactivity to an initial voluntary hyperventilation (i.e., whether participants met criteria for a DSM-IV panic attack; PA) would predict the relative degree of task persistence on a second hyperventilation trial (DT) above and beyond the variance accounted for by anxiety sensitivity (AS), negative affectivity (N...

    The current study utilized the intersectionality framework to explore whether smoking outcome expectancies (i.e., cognitions about the anticipated effects of smoking) were predicted by gender and ethnicity, and the gender-by-ethnicity interaction. In a cross-sectional design, daily smokers from the general community (32.2% women; non-Hispanic African American [n = 175], non-Hispanic White [n = 109], or Hispanic [n = 26]) completed self-report measures on smoking expectancies and other co-factors. Results showed that women reported greater negative reinforcement (i.e., anticipated smoking-induced negative affect reduction) and weight control (i.e., anticipated smoking-induced appetite/weight suppression) expectancies than men. Hispanic (vs. African American or White) smokers endorsed greater negative reinforcement expectancies. A gender-by-ethnicity interaction was found for weight control expectancies, such that White women reported greater weight control expectancies than White men, but no gender differences among African American and Hispanic smokers were found. These findings suggest that gender, ethnicity, and their intersectionality should be considered in research on cognitive mechanisms that may contribute to tobacco-related health disparities.

    Aerosols from eight e-cigarettes at different nicotine levels and flavoring were characterized as particle number size distributions in the range 5.6-560 nm by FMPS and CPC. Results were used to provided osimetry estimates applying the MMPD model.Particle number concentrations varied between 3.26 x 10(9) and 4.09 x 10(9) part cm(-3) for e-liquids without nicotine and between 5.08 x 10(9) and 5.29 x 10(9) part cm(-3) for e-liquids with nicotine. No flavor effects were detected on particle concentration data. Particle size distributions were unimodal with modes between 107-165 nm and 165-255 nm, for number and volume metrics, respectively. Averagely, 6.25 x 10(10) particles were deposited in respiratory tree after a single puff. Highest deposition densities and mean layer thickness of e-cigarette liquid on the lung epithelium were estimated at lobar bronchi. Our study shows that e-cigarette aerosol is source of high particle dose in respiratory system, from 23%to 35% of the daily dose of a no-smoking individual. PMID:25463721

    2011-05-01

    Full Text Available Abstract In order to more fully understand why individuals smoke menthol cigarettes, it is important to understand the perceptions held by youth and adults regarding menthol cigarettes. Perceptions are driven by many factors, and one factor that can be important is marketing. This review seeks to examine what role, if any, the marketing of menthol cigarettes plays in the formation of consumer perceptions of menthol cigarettes. The available literature suggests that menthol cigarettes may be perceived as safer choices than non-menthol cigarettes. Furthermore, there is significant overlap between menthol cigarette advertising campaigns and the perceptions of these products held by consumers. The marketing of menthol cigarettes has been higher in publications and venues whose target audiences are Blacks/African Americans. Finally, there appears to have been changes in cigarette menthol content over the past decade, which has been viewed by some researchers as an effort to attract different types of smokers.

The objectives were to determine the prevalence of smokers in this group and to establish the effectiveness of oral hygiene practices of this group of students. In a first stage, a group of students were asked about their smoking habits, initiating age and amount of cigarettes per day, in order to determine the prevalence of smokers. In a second stage, students were randomized selecting a total of 61 individuals, 32 of them didn't have smoking habits and 29 has it; in order to determine oral hygiene's effectiveness. The age average of non smokers was 23 ±2,109 years old, and of smokers 23,655 ± 1,913 year-old, not existing significant difference between them. Green & Vermillion simplified oral hygiene index was carried out to each student. AlI measures were registered by a gauged examiner to avoid the interexaminer mistake. Information on smoking habits was asked at the end of examination in order to avoid the subjectivity of the clinic examiner. The oral hygiene index assigned for each group was 1,103 (lC 95% 0,344-1,861 for smokers and 1,218 (lC 95% 0,245-2, 191 for non smokers. By confronting data and fixing p value <5%, we conclude that there are no significant differences between the accumulation of supragingival plaque in both groups, and the effectiveness of oral hygiene among young adult smokers and non smokers is similar and acceptable. This study determines smokers prevalence in health-area students, and Iike an advance for future "casecontrol" studies that we'lI carry out in similar populations, in order to control "oral hygiene" variable as a confusin factor in the etiologic causal design that

    2014-09-01

    Full Text Available Despite 50+ years of public health efforts to reduce smoking rates in the United States, approximately one-fifth of the adults living in this country continue to smoke cigarettes. Previous studies have examined smokers’ risk perceptions of cigarette smoking, as well as the perceived benefits of quitting smoking. Less research has focused on the perceived benefits of smoking among current cigarette smokers. The latter is the main focus of the present paper. Questionnaire-based interviews were conducted with a community-based sample of 485 adult current cigarette smokers recruited from the Atlanta, Georgia, metropolitan area between 2004 and 2007. Active and passive recruiting approaches were used, along with a targeted sampling strategy. Results revealed that most current cigarette smokers perceive themselves to experience benefits as a result of their cigarette use, including (among others increased relaxation, diminished nervousness in social situations, enjoyment of the taste of cigarettes when smoking, and greater enjoyment of parties when smoking. Perceiving benefits from cigarette smoking was associated with a variety of tobacco use measures, such as smoking more cigarettes, an increased likelihood of chain smoking, and overall negative attitude toward quitting smoking, among others. Several factors were associated with the extent to which smokers perceived themselves to benefit from their tobacco use, including education attainment, the age of first purchasing cigarettes, the proportion of friends who smoked, hiding smoking from others, being internally-oriented regarding locus of control, and self-esteem.

    Background Cross-national variance in smoking prevalence is relatively well documented. The aim of this study is to estimate levels of smoking persistence across 21 countries with a hypothesized inverse relationship between country income level and smoking persistence. Methods Data from the World Health Organization World Mental Health Survey Initiative were used to estimate cross-national differences in smoking persistence–the proportion of adults who started to smoke and persisted in smoking by the date of the survey. Result There is large variation in smoking persistence from 25% (Nigeria) to 85% (China), with a random-effects meta-analytic summary estimate of 55% with considerable cross-national variation. (Cochran's heterogeneity Q statistic=6,845; p<0.001). Meta-regressions indicated observed differences are not attributable to differences in country income level, age distribution of smokers, or how recent the onset of smoking began within each country. Conclusion While smoking should remain an important public health issue in any country where smokers are present, this report identifies several countries with higher levels of smoking persistence (namely, China and India).

    Research from the Multiethnic Cohort (MEC) demonstrated that, for the same quantity of cigarette smoking, African Americans and Native Hawaiians have a higher lung cancer risk than Whites, while Latinos and Japanese Americans are less susceptible. We collected urine samples from 2,239 cigarette smokers from five different ethnic groups in the MEC and analyzed each sample for S-phenylmercapturic acid (SPMA), a specific biomarker of benzene uptake. African Americans had significantly higher (geometric mean [SE] 3.69 [0.2], p<0.005) SPMA/ml urine than Whites (2.67 [0.13]) while Japanese Americans had significantly lower levels than Whites (1.65 [0.07], p<0.005). SPMA levels in Native Hawaiians and Latinos were not significantly different from those of Whites. We also conducted a genome-wide association study in search of genetic risk factors related to benzene exposure. The glutathione S-transferase T1 (GSTT1) deletion explained between 14.2–31.6% (p = 5.4x10-157) and the GSTM1 deletion explained between 0.2%-2.4% of the variance (p = 1.1x10-9) of SPMA levels in these populations. Ethnic differences in levels of SPMA remained strong even after controlling for the effects of these two deletions. These results demonstrate the powerful effect of GSTT1 status on SPMA levels in urine and show that uptake of benzene in African American, White, and Japanese American cigarette smokers is consistent with their lung cancer risk in the MEC. While benzene is not generally considered a cause of lung cancer, its metabolite SPMA could be a biomarker for other volatile lung carcinogens in cigarette smoke. PMID:26959369

    Mohammed Jawad

    Full Text Available INTRODUCTION: Waterpipe tobacco smoking is receiving growing attention due to accumulating evidence suggesting increasing prevalence in some populations and deleterious health effects. Nevertheless, the relationship between waterpipe and cigarette smoking remain unknown, particularly in low and middle income countries. MATERIALS AND METHODS: We analysed waterpipe and cigarette smoking using data from Global Adult Tobacco Survey, a household survey of adults aged ≥15 years conducted between 2008-2010 in LMICs. Factors associated with waterpipe and cigarette use were assessed using multiple logistic regression. Factors associated with the quantity of waterpipe and cigarette smoking were assessed using log-linear regression models. RESULTS: After adjusting for age, gender, residence, education, occupation and smokeless tobacco use, waterpipe smoking was significantly higher among cigarette users than in non-cigarette users in India (5.6% vs. 0.6%, AOR 13.12, 95% CI 7.41-23.23 and Russia (6.7% vs. 0.2%, AOR 27.73, 95% CI 11.41-67.43, but inversely associated in Egypt (2.6% vs. 3.4%, AOR 0.21, 95% CI 0.15-0.30 and not associated in Vietnam (13.3% vs. 4.7%, AOR 0.96, 95% CI 0.74-1.23. Compared to non-cigarette smokers, waterpipe smokers who also used cigarettes had more waterpipe smoking sessions per week in Russia (1.3 vs. 2.9, beta coefficient 0.31, 95% CI 0.06, 0.57, but less in Egypt (18.2 vs. 10.7, beta coefficient -0.45, 95% CI -0.73, -0.17 and Vietnam (102.0 vs. 79.3, beta coefficient -0.31, 95% CI -0.56, -0.06 and similar amounts in India (29.4 vs. 32.6, beta coefficient -0.12, 95% CI -0.46, 0.22. CONCLUSIONS: Waterpipe smoking is low in most LMICs but important country-level differences in use, including concurrent cigarette smoking, should be taken into account when designing and evaluating tobacco control interventions.

    Anxiety sensitivity (AS; fear of anxiety and internal sensations) has been implicated in a variety of aspects of smoking, including difficulties achieving and maintaining abstinence during tobacco cessation. However, research has yet to evaluate whether AS impacts premature termination of initiating a quit attempt. Therefore, the aim of the present investigation was to explore the extent to which AS was associated with tobacco cessation dropout, as indexed by attendance on the scheduled quit day visit. Participants included 84 adult daily cigarette smokers (61.7% male; Mage=34.6years, SD=13.9), who were recruited to participate in a self-guided quit attempt (an attempt to quit smoking without professional or pharmacological aid). Results indicated that after controlling for the effects of participant sex, race, current (past month) psychological disorder, cigarettes smoked per day, number of years as a regular smoker, and pre-quit levels of motivation to quit, AS significantly predicted increased odds of study dropout prior to attending the scheduled quit day. These findings suggest that AS may be a mechanism involved with challenges in the initiation of quitting. PMID:26896560

    2015-01-01

    The use of electronic cigarettes (e-cigarettes) is experiencing unprecedented growth. This can be contrasted to the use of conventional cigarettes which showed a decrease among adults with the current smoker prevalence dropping from 20.9% in 2005 to 17.8% in 2013. There is some data that e-cigarettes are attracting both former smokers and never smokers, and in particular, young people as users. Currently most states do not tax e-cigarettes. Taxation and regulation may have a similar overall goal of decreasing smoking but regulation tends to focus reduced availability of products. In terms of tobacco control, taxation focuses on the demand side of the equation. Taxation is a distinct strategy from regulation and has been shown to decrease new adopters of conventional cigarettes. A variety of potential taxation strategies can be considered by policymakers based on different assumptions about e-cigarettes and their utility, ranging from untaxed to taxation at moderate levels compared to conventional cigarettes to taxation equal to conventional cigarettes. Until more evidence for the benefits of e-cigarettes is presented, it seems prudent to view them as a potentially harmful and addictive product that ought to be regulated and taxed in an equivalent manner to conventional cigarettes.

    Full Text Available Cigarette warning labels are important sources of risk information, but warning research for other tobacco products is limited. This study aimed to gauge perceptions about warnings that may be used for e-cigarettes. We conducted six small focus groups in late 2014/early 2015 with adult current e-cigarette users and cigarette-only smokers. Participants rated and discussed their perceptions of six e-cigarette warning statements, and warnings in two existing Vuse and MarkTen e-cigarette ads. Participants were open to e-cigarette warnings and provided the strongest reactions to statements warning that e-liquid/e-vapor or e-cigarettes can be poisonous, contain toxins, or are “not a safe alternative to smoking”. However, many also noted that these statements were exaggerated, potentially misleading, and could scare smokers away from reducing their harm by switching to e-cigarettes. Opinions on the Food and Drug Administration’s proposed nicotine addiction warning and warnings that e-cigarettes had not been approved for smoking cessation or had unknown health effects were mixed. Participants perceived MarkTen’s advertisement warning to be stronger and more noticeable than Vuse’s. Care should be taken in developing e-cigarette warnings given their relative recentness and potential for harm reduction compared to other tobacco products. Additional research, including with varied audiences, would be instructive.

  10. The effect of systematic clinical interventions with cigarette smokers on quit status and the rates of smoking-related primary care office visits.

    Thomas G Land

    Full Text Available BACKGROUND: The United States Public Health Service (USPHS Guideline for Treating Tobacco Use and Dependence includes ten key recommendations regarding the identification and the treatment of tobacco users seen in all health care settings. To our knowledge, the impact of system-wide brief interventions with cigarette smokers on smoking prevalence and health care utilization has not been examined using patient population-based data. METHODS AND FINDINGS: Data on clinical interventions with cigarette smokers were examined for primary care office visits of 104,639 patients at 17 Harvard Vanguard Medical Associates (HVMA sites. An operational definition of "systems change" was developed. It included thresholds for intervention frequency and sustainability. Twelve sites met the criteria. Five did not. Decreases in self-reported smoking prevalence were 40% greater at sites that achieved systems change (13.6% vs. 9.7%, p<.01. On average, the likelihood of quitting increased by 2.6% (p<0.05, 95% CI: 0.1%-4.6% per occurrence of brief intervention. For patients with a recent history of current smoking whose home site experienced systems change, the likelihood of an office visit for smoking-related diagnoses decreased by 4.3% on an annualized basis after systems change occurred (p<0.05, 95% CI: 0.5%-8.1%. There was no change in the likelihood of an office visit for smoking-related diagnoses following systems change among non-smokers. CONCLUSIONS: The clinical practice data from HVMA suggest that a systems approach can lead to significant reductions in smoking prevalence and the rate of office visits for smoking-related diseases. Most comprehensive tobacco intervention strategies focus on the provider or the tobacco user, but these results argue that health systems should be included as an integral component of a comprehensive tobacco intervention strategy. The HVMA results also give us an indication of the potential health impacts when meaningful use core

    Results from the Multiethnic Cohort Study demonstrated significant differences in lung cancer risk among cigarette smokers from five different ethnic/racial groups. For the same number of cigarettes smoked, and particularly among light smokers, African Americans and Native Hawaiians had the highest risk for lung cancer, Whites had intermediate risk, while Latinos and Japanese Americans had the lowest risk. We analyzed urine samples from 331–709 participants from each ethnic group in this study for metabolites of phenanthrene, a surrogate for carcinogenic polycyclic aromatic hydrocarbon exposure. Consistent with their lung cancer risk and our previous studies of several other carcinogens and toxicants of cigarette smoke, African Americans had significantly (p<0.0001) higher median levels of the two phenanthrene metabolites 3-hydroxyphenanthrene (3-PheOH, 0.931 pmol/ml) and phenanthrene tetraol (PheT, 1.13 pmol/ml) than Whites (3-PheOH, 0.697 pmol/ml; PheT, 0.853 pmol/ml) while Japanese-Americans had significantly (p = 0.002) lower levels of 3-PheOH (0.621 pmol/ml) than Whites. PheT levels (0.838 pmol/ml) in Japanese-Americans were not different from those of Whites. These results are mainly consistent with the lung cancer risk of these three groups, but the results for Native Hawaiians and Latinos were more complex. We also carried out a genome wide association study in search of factors that could influence PheT and 3-PheOH levels. Deletion of GSTT1 explained 2.2% of the variability in PheT, while the strongest association, rs5751777 (p = 1.8x10-62) in the GSTT2 gene, explained 7.7% of the variability in PheT. These GWAS results suggested a possible protective effect of lower GSTT1 copy number variants on the diol epoxide pathway, which was an unexpected result. Collectively, the results of this study provide further evidence that different patterns of cigarette smoking are responsible for the higher lung cancer risk of African Americans than of Whites and the

    Full Text Available Abstract Background Describe the recent evolution of cigarette smoking habits by gender in Geneva, where incidence rates of lung cancer have been declining in men but increasing in women. Methods Continuous cross-sectional surveillance of the general adult (35–74 yrs population of Geneva, Switzerland for 11 years (1993–2003 using a locally-validated smoking questionnaire, yielding a representative random sample of 12,271 individuals (6,164 men, 6,107 women. Results In both genders, prevalence of current cigarette smoking was stable over the 11-year period, at about one third of men and one quarter of women, even though smoking began at an earlier age in more recent years. Older men were more likely to be former smokers than older women. Younger men, but not women, tended to quit smoking at an earlier age. Conclusion This continuous (1993–2003 risk factor surveillance system, unique in Europe, shows stable prevalence of smoking in both genders. However, sharp contrasts in age-specific prevalence of never and former smoking and of ages at smoking initiation indicate that smoking continues a long-term decline in men but has still not reached its peak in women.

    2008-02-01

    The present investigation evaluated the incremental validity of negative reinforcement/negative affect reduction smoking outcome expectancies in the prediction of anxious and fearful responding to bodily sensations. Participants included 171 daily smokers (82 women, 89 men; mean age = 25.67 years, SD = 10.54). Consistent with prediction, negative reinforcement/negative affect reduction smoking outcome expectancies were significantly predictive of anxiety focused on bodily sensations and postchallenge intensity of cognitive panic attack symptoms, but not of physical panic symptoms. The observed effects were evident above and beyond the statistically significant variance accounted for by the covariates of anxiety sensitivity, negative affectivity, cigarettes per day, and weekly alcohol use and independent of other smoking outcome expectancy factors. Findings are discussed in terms of the role of negative reinforcement/negative affect reduction smoking outcome expectancies and vulnerability for panic symptoms and psychopathology. PMID:18266553

    The Multiethnic Cohort epidemiology study has clearly demonstrated that, compared to Whites and for the same number of cigarettes smoked, African Americans and Native Hawaiians have a higher risk for lung cancer whereas Latinos and Japanese Americans have a lower risk. Acrolein and crotonaldehyde are two important constituents of cigarette smoke which have well documented toxic effects and could play a role in lung cancer etiology. Their urinary metabolites 3-hydroxypropylmercapturic acid (3-HPMA) and 3-hydroxy-1-methylpropylmercapturic acid (HMPMA), respectively, are validated biomarkers of acrolein and crotonaldehyde exposure. We quantified levels of 3-HPMA and HMPMA in the urine of more than 2200 smokers from these five ethnic groups, and also carried out a genome wide association study using blood samples from these subjects. After adjusting for age, sex, creatinine, and total nicotine equivalents, geometric mean levels of 3-HPMA and HMPMA were significantly different in the five groups (P<0.0001). Native Hawaiians had the highest and Latinos the lowest geometric mean levels of both 3-HPMA and HMPMA. Levels of 3-HPMA and HMPMA were 3787 and 2759 pmol/ml urine, respectively, in Native Hawaiians and 1720 and 2210 pmol/ml urine in Latinos. These results suggest that acrolein and crotonaldehyde may be involved in lung cancer etiology, and that their divergent levels may partially explain the differing risks of Native Hawaiian and Latino smokers. No strong signals were associated with 3-HPMA in the genome wide association study, suggesting that formation of the glutathione conjugate of acrolein is mainly non-enzymatic, while the top significant association with HMPMA was located on chromosome 12 near the TBX3 gene, but its relationship to HMPMA excretion is not clear.

    Introduction Cigarette smoke contributes to a diverse range of diseases including chronic obstructive pulmonary disease (COPD), cardiovascular disorders and many cancers. There currently is a need for human challenge models, to assess the acute effects of a controlled cigarette smoke stimulus, followed by serial sampling of blood and respiratory tissue for advanced molecular profiling. We employ precision sampling of nasal mucosal lining fluid by absorption to permit soluble mediators measurement in eluates. Serial nasal curettage was used for transcriptomic analysis of mucosal tissue. Methods and analysis Three groups of strictly defined patients will be studied: 12 smokers with COPD (GOLD Stage 2) with emphysema, 12 matched smokers with normal lung function and no evidence of emphysema, and 12 matched never smokers with normal spirometry. Patients in the smoking groups are current smokers, and will be given full support to stop smoking immediately after this study. In giving a controlled cigarette smoke stimulus, all patients will have abstained from smoking for 12 h, and will smoke two cigarettes with expiration through the nose in a ventilated chamber. Before and after inhalation of cigarette smoke, a series of samples will be taken from the blood, nasal mucosal lining fluid and nasal tissue by curettage. Analysis of plasma nicotine and metabolites in relation to levels of soluble inflammatory mediators in nasal lining fluid and blood, as well as assessing nasal transcriptomics, ex vivo blood platelet aggregation and leucocyte responses to toll-like receptor agonists will be undertaken. Implications Development of acute cigarette smoke challenge models has promise for the study of molecular effects of smoking in a range of pathological processes. Ethics and dissemination This study was approved by the West London National Research Ethics Committee (12/LO/1101). The study findings will be presented at conferences and will be reported in peer-reviewed journals

    A randomized, multi-center study of adult cigarette smokers switched to tobacco-heating cigarettes, snus or ultra-low machine yield tobacco-burning cigarettes (50/group) was conducted, and subjects' experience with the products was followed for 24 weeks. Differences in biomarkers of tobacco exposure between smokers and never smokers at baseline and among groups relative to each other and over time were assessed. Results indicated reduced exposure to many potentially harmful constituents found in cigarette smoke following product switching. Findings support differences in exposure from the use of various tobacco products and are relevant to the understanding of a risk continuum among tobacco products (ClinicalTrials.gov Identifier: NCT02061917).

    Full Text Available Cigarette smokers are being encouraged to use smokeless tobacco (SLT in locations where smoking is banned. We examined state-wide data from Minnesota to measure changes over time in the use of SLT and concurrent use of cigarettes and SLT. The Minnesota Adult Tobacco Survey was conducted four times between 1999 and 2010 and has provided state-wide estimates of cigarette smoking, SLT use and concurrent use of SLT by smokers. The prevalence of SLT was essentially unchanged through 2007, then increased significantly between 2007 and 2010 (3.1% versus 4.3%, P<0.05. Similarly, the prevalence of cigarette smokers who reported using SLT was stable then increased between 2007 and 2010 (4.4% versus 9.6%, P<0.05. The finding of higher SLT use by smokers could indicate that smokers in Minnesota are in an experimental phase of testing alternative products as they adjust to recent public policies restricting smoking in public places. The findings are suggestive that some Minnesota smokers are switching to concurrent use of cigarettes and SLT. Future surveillance reports will be necessary to confirm the results.

    Cigarette smoking during young adult may result in serious health issues in later life. Hence, it is extremely necessary to study the smoking neurophysiological mechanisms in this critical transitional period. However, few studies revealed the electrophysiological mechanisms of cognitive processing biases in young adult smokers. In present study, nineteen young smokers with 12h abstinent and 19 matched nonsmokers were recruited. By employing event-related potentials (ERP) measurements during a smoking cue induced craving task, electrophysiological brain responses were compared between the young adult smokers and nonsmokers. The Slow Positive Wave (SPW) amplitude of smoking-related cues was enhanced in young adult smokers compared with nonsmokers. In addition, increased P300/SPW component of smoking-related cues relative to neutral cues were found in young adult smokers. Meanwhile, a positive correlation between Cigarette Per Day (CPD) and the amplitude of ERPs wave (P300/SPW) at anterior (Fz), central (Cz) were observed in young adult smokers. Our findings provided direct electrophysiological evidence for the cognitive processing bias of smoking cue and may shed new insights into the smoking behavior in young adult smokers. PMID:27373532

    Langerhans cell histiocytosis (LCH) is a rare myeloid neoplasm characterized by the proliferation and dissemination of histiocytes. These in turn may cause symptoms ranging from isolated, infiltrative lesions to severe multisystem disease. Pulmonary Langerhans cell histiocytosis (PLCH) presents as a localized polyclonal proliferation of Langerhans cells in the lungs causing bilateral cysts and fibrosis. In adults, this rare condition is considered a reactive process associated with cigarette smoking.

We conducted a meta-analysis to systematically assess the potential association. Methods: PubMed and EMBASE were searched from the date of their inception to October 1, 2015, to identify relevant articles. Reference lists from these articles were reviewed to identify additional studies. Both cohort and case–control studies were included. Fixed-effects models were used to calculate the overall relative risk (RR with corresponding 95% confidence intervals (CIs. Results: The final analysis included 24 studies (seven cohort and 17 case–control studies, involving more than 2.3 million individuals. The combined RR was 1.04 (95% CI: 1.00, 1.09; P=0.073 for ever-smokers, 0.97 (95% CI: 0.88, 1.07; P=0.574 for current-smokers, and 1.07 (95% CI: 0.98, 1.16; P=0.130 for past smokers, with little evidence of heterogeneity. Omission of any single study from the analysis had little effect on the result. No evidence of publication bias was found. A small but statistically significant increase was found in past smokers in females (RR: 1.13, 95% CI: 1.00, 1.28; P=0.046 but not in males. Conclusion: In general, there was no association between cigarette smoking and adult glioma. The small but statistically significant association in females requires further investigation.

    The association between passive cigarette smoke exposure and breast cancer risk is inconclusive and may be modified by genotype. The authors investigated lifetime passive cigarette smoke exposures, 36 variants in 12 carcinogen-metabolizing genes, and breast cancer risk among Ontario, Canada, women who had never smoked (2003-2004). DNA (saliva) was available for 920 breast cancer cases and 960 controls. Detailed information about passive smoke exposure was collected for multiple age periods (childhood, teenage years, and adulthood) and environments (home, work, and social). Adjusted odds ratios and 95% confidence intervals were estimated by multivariable logistic regression, and statistical interactions were assessed using the likelihood ratio test. Among postmenopausal women, most associations between passive smoke and breast cancer risk were null, whereas among premenopausal women, nonsignificant positive associations were observed. Significant interactions were observed between certain types of passive smoke exposure and genetic variants in CYP2E1, NAT2, and UGT1A7. While these interactions were statistically significant, the magnitudes of the effect estimates were not consistent or easily interpretable, suggesting that they were perhaps due to chance. Although the results of this study were largely null, it is possible that premenopausal women exposed to passive smoke or carrying certain genetic variants may be at higher risk of breast cancer.

    2014-06-01

    Full Text Available A carefully structured Tobacco Harm Reduction (THR initiative, with e-cigarettes as a prominent THR modality, added to current tobacco control programming, is the most feasible policy option likely to substantially reduce tobacco-attributable illness and death in the United States over the next 20 years. E-cigarettes and related vapor products are the most promising harm reduction modalities because of their acceptability to smokers. There are about 46 million smokers in the United States, and an estimated 480,000 deaths per year attributed to cigarette smoking. These numbers have been essentially stable since 2004. Currently recommended pharmaceutical smoking cessation protocols fail in about 90% of smokers who use them as directed, even under the best of study conditions, when results are measured at six to twelve months. E-cigarettes have not been attractive to non-smoking teens or adults. Limited numbers non-smokers have experimented with them, but hardly any have continued their use. The vast majority of e-cigarette use is by current smokers using them to cut down or quit cigarettes. E-cigarettes, even when used in no-smoking areas, pose no discernable risk to bystanders. Finally, addition of a THR component to current tobacco control programming will likely reduce costs by reducing the need for counseling and drugs.

    2011-01-01

    Full Text Available Abstract Background It has been suggested that cigarette smokers will switch to alternative oral nicotine delivery products to reduce their health risks if informed of the relative risk difference. However, it is important to assess how smokers are likely to use cigarette alternatives before making predictions about their potential to promote individual or population harm reduction. Objectives This study examines smokers' interest in using a smokeless tobacco or a nicotine replacement product as a substitute for their cigarettes. Methods The study included 67 adult cigarette smokers, not currently interested in quitting, who were given an opportunity to sample four alternative oral nicotine products: 1 Camel Snus, 2 Marlboro Snus, 3 Stonewall dissolvable tobacco tablets, and 4 Commit nicotine lozenges. At visit 1, subjects were presented information about the relative benefits/risks of oral nicotine delivery compared to cigarettes. At visit 2, subjects were given a supply of each of the four products to sample at home for a week. At visit 3, subjects received a one-week supply of their preferred product to see if using such products reduced or eliminated cigarette use. Results After multiple product sampling, participants preferred the Commit lozenges over the three smokeless tobacco products (p = 0.011. Following the one week single-product trial experience, GEE models controlling for gender, age, level of education, baseline cigarettes use, and alternative product chosen, indicated a significant decline in cigarettes smoked per day across one week of single-product sampling (p Conclusions Findings from this study show that smokers, who are currently unwilling to make a quit attempt, may be willing to use alternative products in the short term as a temporary substitute for smoking. However, this use is more likely to be for partial substitution (i.e. they will continue to smoke, albeit at a lower rate rather than complete substitution. Of the

    The present study examined the relation between the big five personality traits and any lifetime cigarette use, progression to daily smoking, and smoking persistence among adults in the United States (US) over a ten-year period. Data were drawn from the Midlife Development in the US (MIDUS) I and II (N = 2101). Logistic regression was used to examine the relationship between continuously measured personality factors and any lifetime cigarette use, smoking progression, and smoking persistence at baseline (1995-1996) and at follow-up (2004-2006). The results revealed that higher levels of openness to experience and neuroticism were each significantly associated with increased risk of any lifetime cigarette use. Neuroticism also was associated with increased risk of progression from ever smoking to daily smoking and persistent daily smoking over a ten-year period. In contrast, conscientiousness was associated with decreased risk of lifetime cigarette use, progression to daily smoking, and smoking persistence. Most, but not all, associations between smoking and personality persisted after adjusting for demographic characteristics, depression, anxiety disorders, and substance use problems. The findings suggest that openness to experience and neuroticism may be involved in any lifetime cigarette use and smoking progression, and that conscientiousness appears to protect against smoking progression and persistence. These data add to a growing literature suggesting that certain personality factors--most consistently neuroticism--are important to assess and perhaps target during intervention programs for smoking behavior.

    Light and intermittent smoking has become a prevalent pattern of use among young adults. Little is known about which factors differentiate light and intermittent smokers (LITS) from heavy smokers (HS) in young adulthood. In this study, we compare young adult LITS with HS with regard to demographic- and smoking-related variables, self-control abilities, and concrete strategies of smoking restraint. The data were collected as part of an Ecological Momentary Assessment (EMA) study with 137 German young adult smokers (M Age = 21.1 years, 46.0% female; 76 HS [≥10 cigarettes/day] and 61 LITS [≤5 cigarettes/day]).

    Full Text Available Introduction: In 2012 in China, 52.9% of men were reported to smoke while only 2.4% of women smoked. This study explored the smoking-related Knowledge, Attitudes and Practices (KAP among young adult male smokers. Methods: A cross-sectional study was conducted in four municipal areas of Chongqing using a questionnaire administered to 536 natives young male smokers aged 18–45 years old. Results: The total score of smoking cognition, the total score of smoking attitude and the total score of positive behavior to quit smoking was significantly different among the three groups by education. Besides, 30.97% of male smokers never seriously thought about quitting smoking. Logistic regression analysis found smoking-related knowledge, attitudes, behaviors and sociodemographic factors affect having smoking cessation idea. But no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking in a sample of higher education. No statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.03012, p = 0.6811, and also no statistically significant correlation was observed between smoking cognition and positive behavior to quit smoking (Pearson correlation coefficient = 0.08869, p = 0.2364  in the sample of higher education young adult males Conclusions: Young adult males with higher education have a better knowledge of smoking hazards and a more positive attitude toward smoking, however, this knowledge and attitude do not necessarily translate into health behavioral outcomes such as not smoking. Overall the present findings indicate that no statistically significant correlation between the education level and quitting smoking idea exists among young adult male smokers in China. This survey gives a snapshot of the impact of education on smoking-related KAP among young adults male smokers.

    Although cigarette smoking has substantially declined since the release of the 1964 Surgeon General's report on smoking and health,* disparities in tobacco use exist among racial/ethnic populations (1). Moreover, because estimates of U.S. adult cigarette smoking and tobacco use are usually limited to aggregate racial or ethnic population categories (i.e., non-Hispanic whites [whites]; non-Hispanic blacks or African Americans [blacks]; American Indians and Alaska Natives [American Indians/Alaska Natives]; Asians; Native Hawaiians or Pacific Islanders [Native Hawaiians/Pacific Islanders]; and Hispanics/Latinos [Hispanics]), these estimates can mask differences in cigarette smoking prevalence among subgroups of these populations. To assess the prevalence of and changes in cigarette smoking among persons aged ≥18 years in six racial/ethnic populations and 10 select subgroups in the United States,(†) CDC analyzed self-reported data collected during 2002-2005 and 2010-2013 from the National Survey on Drug Use and Health (NSDUH) (2) and compared differences between the two periods. During 2010-2013, the overall prevalence of cigarette smoking among the racial/ethnic populations and subgroups ranged from 38.9% for American Indians/Alaska Natives to 7.6% for both Chinese and Asian Indians. During 2010-2013, although cigarette smoking prevalence was relatively low among Asians overall (10.9%) compared with whites (24.9%), wide within-group differences in smoking prevalence existed among Asian subgroups, from 7.6% among both Chinese and Asian Indians to 20.0% among Koreans. Similarly, among Hispanics, the overall prevalence of current cigarette smoking was 19.9%; however, within Hispanic subgroups, prevalences ranged from 15.6% among Central/South Americans to 28.5% among Puerto Ricans. The overall prevalence of cigarette smoking was higher among men than among women during both 2002-2005 (30.0% men versus 23.9% women) and 2010-2013 (26.4% versus 21.1%) (p<0.05). These

    2016-01-01

    Full Text Available Introduction Low socioeconomic status is associated with high rates of cigarette smoking, and socioeconomic differences in cigarette smoking tend to emerge during young adulthood. To further our understanding of socioeconomic differences in smoking among young adults, we examined correlates of smoking, with attention to multiple socioeconomic indicators that have not been examined in this population. Methods We analyzed data from the 2011–2012 California Health Interview Survey. The analytic sample consisted of young adults aged 18–30 years who were considered socioeconomically disadvantaged as measured by education and poverty. Logistic regression analyses were conducted to examine factors associated with smoking status in this group, and multinomial logistic regression analyses were conducted to examine correlates of smoking frequency. Results In this sample (N = 1,511; 48% female, 66% Hispanic/Latino, 18% non-Hispanic white, 39.7% reported experiencing food insecurity in the past year. Smoking prevalence was significantly higher among young adults who reported being food insecure (26.9% than among those who reported being food secure (16.4%. Past-year food insecurity was significantly associated with current smoking, independent of sociodemographic characteristics and alcohol use. Specifically, food insecurity was significantly associated with daily but not nondaily smoking. Conclusion Socioeconomically disadvantaged young adults with food insecurity may be considered a high-risk group with respect to cigarette smoking. Efforts to reduce tobacco-related health disparities should address diverse sources of socioeconomic influences, including experiences of food insecurity.

    Full Text Available This study is intended to evaluate the changes in Electrocardiogram (ECG in apparently healthy adult male smokers. This cross-sectional study covers 40 smokers, who smoked on an average 10 cigarettes per day for at least 5 years, and 40 non-smokers to find out the possible risk factors for cardiovascular disorders. This study was conducted during April 2011 to April 2012 in the Department of Physiology of Andhra Medical College, on subjects whose age ranged from 20 to 60 years. The ECG results were evaluated for different parameters like heart rate, P-wave, P-R interval, QRS complex, QT interval, and T-wave. The results were analyzed using student’s t-test. The probability (p value was calculated. The analysis showed that QRS and QT interval were shortened and that the QTc interval was widened in the smokers, although the values did not show any statistical significance. From the statistical analysis of the results obtained in the present study and their comparison with those of published reports, it appears that smoking 10 cigarettes per day for 5 Years does not cause major change in ECG wave forms.

    BACKGROUND: Use of electronic cigarettes (e-cigarettes) among adolescents has increased since their introduction into the US market in 2007. Little is known about the role of e-cigarette psychosocial factors on risk of e-cigarette or cigarette use in adolescence. METHODS: Information on e-cigarette and cigarette psychosocial factors (use and attitudes about use in the home and among friends) was collected from 11th- and 12th-grade participants in the Southern California Children’s Health Study during the spring of 2014. RESULTS: Of 2084 participants, 499 (24.0%) had used an e-cigarette, including 200 (9.6%) current users (past 30 days); 390 participants (18.7%) had smoked a combustible cigarette, and 119 (5.7%) were current cigarette smokers. Cigarette and e-cigarette use were correlated. Nevertheless, 40.5% (n = 81) of current e-cigarette users had never smoked a cigarette. Psychosocial factors (home use of each product, friends’ use of and positive attitudes toward e-cigarettes and cigarettes) and participant perception of the harm of e-cigarettes were strongly positively associated both with e-cigarette and cigarette use. Most youth who reported e-cigarette use had friends who used e-cigarettes, and almost half of current users reported that they did not believe there were health risks associated with e-cigarette use. CONCLUSIONS: Longitudinal studies of adolescents are needed to determine whether the strong association of e-cigarette psychosocial factors with both e-cigarette and cigarette use will lead to increased cigarette use or dual use of cigarettes and e-cigarettes, or whether e-cigarettes will serve as a gateway to cigarette use.

    Cigarette smoking may be one of the factors contributing to the high levels of cancer-related mortality experienced by certain Asian/Pacific Islander (A/PI) subgroups (e.g., Native Hawaiian). Given the collectivist cultural orientation attributed to A/PI groups, social strategies are recommended for substance abuse or smoking cessation treatment among A/PI. However, research examining how social network characteristics and social support relate to smoking across A/PI subgroups has been lacking. This study investigated the associations between social network characteristics (e.g., size, composition), perceived social support, and recent cigarette use across Native Hawaiian, Filipino, and East Asian (e.g., Japanese, Chinese) young adults (18-35 year old). Cross-sectional, self-report data were collected from N = 435 participants (M age = 25.6, SD = 8.3; 61% women). Ethnic differences were found in a number of pathways linking social network characteristics, perceived social support, and cigarette smoking. Larger network size was strongly associated with higher perceived social support and lower recent cigarette smoking among Native Hawaiians but not Filipinos or East Asians. Higher perceived social support was associated with lower recent smoking among East Asians and Filipinos but not Native Hawaiians. Implications are discussed with regard to smoking prevention and cessation among A/PI. PMID:27297612

Cross-sectional, self-report data were collected from N = 435 participants (M age = 25.6, SD = 8.3; 61% women). Ethnic differences were found in a number of pathways linking social network characteristics, perceived social support, and cigarette smoking. Larger network size was strongly associated with higher perceived social support and lower recent cigarette smoking among Native Hawaiians but not Filipinos or East Asians. Higher perceived social support was associated with lower recent smoking among East Asians and Filipinos but not Native Hawaiians. Implications are discussed with regard to smoking prevention and cessation among A/PI.

    Although smoking initiation typically occurs during adolescence, most preclinical studies of tobacco use involve adult animals. Furthermore, their focus is largely on nicotine alone, even though cigarette smoke contains thousands of constituents. The present study therefore aimed to determine whether aqueous constituents in cigarette smoke affect acquisition of nicotine self-administration during adolescence in rats. Adolescent and adult male rats, aged postnatal day (P) 25 and 85, respectively, were food trained on a fixed ratio 1 (FR1) schedule, then allowed to self-administer one of 5 doses of nicotine (0, 3.75, 7.5, 15, or 30 μg/kg) or aqueous cigarette smoke extract (CSE) with equivalent nicotine content. Three progressively more difficult schedules of reinforcement, FR1, FR2, and FR5, were used. Both adolescent and adult rats acquired self-administration of nicotine and CSE. Nicotine and CSE similarly increased non-reinforced responding in adolescents, leading to enhanced overall drug intake as compared to adults. When data were corrected for age-dependent alterations in non-reinforced responding, adolescents responded more for low doses of nicotine and CSE than adults at the FR1 reinforcement schedule. No differences in adolescent responding for the two drugs were seen at this schedule, whereas adults had fewer responses for CSE than for nicotine. However, when the reinforcement schedule was increased to FR5, animals dose-dependently self-administered both nicotine and CSE, but no drug or age differences were observed. These data suggest that non-nicotine tobacco smoke constituents do not influence the reinforcing effect of nicotine in adolescents. PMID:27346207

    China has a huge population of cigarette smokers and investigation on their consumer psychology and smoking habit or preferences are necessary to understand and interfere with their smoking behavior. To determine smoking preference caused by dietary habits and relationship between the cigarette aroma components and the smoking preference in Chinese smokers, a large-scale survey, which involves 2,096 smokers in five different geographical cities (Hangzhou, Guangzhou, Chengdu, Shenyang and Lanzhou) where represent different dietary habits, was conducted by this study. Sensory evaluation of smoking different cigarette branches at different location/seasons was carried out by a 7-members team. To determine key aroma components which influence the smoking preference of Chinese smokers, compositions of mainstream smoke were measured by chemical analysis methods.Our results indicated that (1) dietary habits of smokers had a significant impact on smoking preferences, for an instance, smokers who prefer spicy flavor had higher requirements on aroma quality, fullness and aftertaste of cigarette; (2) several aroma components of mainstream smoke had apparent influence on sensory quality;(3) some aroma chemical compositions of cigarette, including 2,5-dimethyl-pyridine, 2-ethyl furan, 3,4-dimethyl-2-hydroxy-2-cyclopenten-1-ketone, ZZZ,9,12,15-eighteen trienoic acid methyl ester and bitterness , were associated with dietary habit and smoking preferences. Taken together, this study provides useful data for reasonable cigarette consumption and smoking control in China.%我国吸烟群体巨大,其消费心理和行为偏好等人文因素研究,可以准确了解和干预吸烟行为。为了研究吸烟人群不同饮食习惯引起的吸烟(烟气)偏好及其引起偏好的卷烟香味成分因素,对杭州、广州、成都、沈阳和兰州5个不同区域吸烟人群进行了大规模群体调查,根据特定人群评吸卷烟样品感官评价结果,和化学

    Full Text Available Abstract Background Cigarette taxation has been perceived by academics and policy-makers as one of the most effective ways of reducing the use of cigarettes. On January 1 2002, the Taiwan government imposed a New Taiwan (NT $5 per pack tax earmarked for the purpose of tobacco control. This study uses a survey collected prior to taxation to assess public attitudes toward cigarette taxation, public beliefs about the effectiveness of cigarette taxation at reducing cigarette use and public opinions about the allocation of this tax revenue. Methods Data were drawn from a national face-to-face interview on cigarette consumption in 2000. A total of 3,279 adults were aged 18 to 64 years; 49.9% of whom were male and 50.1% female, and with a smoking prevalence of 49.1% and 4.1%, respectively. The attitudes toward cigarette tax were analysed using multi-logit regressions. We analysed by logistic regression the potential changes in smoking behaviour that smokers might make in response to the five NT (New Taiwan dollar earmarked tax on cigarettes per pack. We summarized public opinions about the allocation of earmarked tax revenue using descriptive statistics. Results Current smokers (OR = 0.34 and former smokers (OR = 0.68 were less likely to support the cigarette tax than non-smokers. A favourable attitude toward the tax was positively associated with personal monthly income, especially among females. Among male smokers, the possibility of reducing/quitting smoking in response to the five-NT-dollar tax was negatively associated with the monthly expense for smoking. The two most frequently-suggested areas to receive money from the revenue collected from the earmarked tax were health education and cancer subsidy. Conclusions Smoking status and economic factors determine the attitude and potential responses of people toward the cigarette tax. Taiwan's five NT-dollar earmarked tax for cigarettes may have only a limited effect upon the reduction in cigarette

    Full Text Available Despite increases in nondaily smoking among young adults, no prior research has aimed to develop and test an intervention targeting this group. Thus, we aimed to develop and test the feasibility, acceptability, and potential effectiveness of an online intervention targeting college student nondaily smokers. We conducted a one-arm feasibility and acceptability trial of a four-week online intervention with weekly contacts among 31 college student nondaily smokers. We conducted assessments at baseline (B, end of treatment (EOT, and six-week followup (FU. We maintained a 100% retention rate over the 10-week period. Google Analytics data indicated positive utilization results, and 71.0% were satisfied with the program. There were increases (P<.001 in the number of people refraining from smoking for the past 30 days and reducing their smoking from B to EOT and to FU, with additional individuals reporting being quit despite recent smoking. Participants also increased in their perceptions of how bothersome secondhand smoke is to others (P<.05; however, no other attitudinal variables were altered. Thus, this intervention demonstrated feasibility, acceptability, and potential effectiveness among college-aged nondaily smokers. Additional research is needed to understand how nondaily smokers define cessation, improve measures for cessation, and examine theoretical constructs related to smoking among this population.

    Full Text Available Background: The increasing number of children and young adults exposed to tobacco usage in the world is alarming. Indonesia is the third biggest tobacco consumer in the world after China and India. Smoking harms nearly every organ of the body, it reduce quality of life and life expectancy. Smoking causes illnesses, big economic lost and premature death. Tobacco use was the leading cause of preventable death. Smokers began at early age; they became the target of massive tobacco campaigns. Youth were vulnerable to tobacco advertising, once they began to smoke, it was difficult to quit. The Objectives of this paper is to identify tobacco usage among the Indonesian youth, to explore health problems, regulations related to tobacco consumption and efforts to implement the WHO Framework Convention on Tobacco Control. Methods: Method used is by reviewing studies and campaign information provided by researchers and practitioners in tobacco control programs. Result: Data shows that among people aged 10 to 24 years in Indonesia the current smokers were 23.7% daily smokers, 5.5% occasional smokers while the average cigarettes consumed daily were 12.2. Among lndonesian aged 13-15 years, there were 41% boys and 3.5% girls that were current cigarette smoking and 10.3% boys and 3,1% girls that had current tobacco other than cigarette. It is important that this preventable epidemic becomes a top public health issue in all countries. A complete ban on all tobacco advertising, promotion and sponsorship is a powerful tool to protect the world's youth and Indonesia should ratify tobacco ban. Key words: Indonesia, tobacco, youth, advertisement

  2. "A cigarette a day keeps the goodies away": smokers show automatic approach tendencies for smoking--but not for food-related stimuli.

    Directory of Open Access Journals (Sweden)

    Alla Machulska

    Full Text Available Smoking leads to the development of automatic tendencies that promote approach behavior toward smoking-related stimuli which in turn may maintain addictive behavior. The present study examined whether automatic approach tendencies toward smoking-related stimuli can be measured by using an adapted version of the Approach-Avoidance Task (AAT. Given that progression of addictive behavior has been associated with a decreased reactivity of the brain reward system for stimuli signaling natural rewards, we also used the AAT to measure approach behavior toward natural rewarding stimuli in smokers. During the AAT, 92 smokers and 51 non-smokers viewed smoking-related vs. non-smoking-related pictures and pictures of natural rewards (i.e. highly palatable food vs. neutral pictures. They were instructed to ignore image content and to respond to picture orientation by either pulling or pushing a joystick. Within-group comparisons revealed that smokers showed an automatic approach bias exclusively for smoking-related pictures. Contrary to our expectations, there was no difference in smokers' and non-smokers' approach bias for nicotine-related stimuli, indicating that non-smokers also showed approach tendencies for this picture category. Yet, in contrast to non-smokers, smokers did not show an approach bias for food-related pictures. Moreover, self-reported smoking attitude could not predict approach-avoidance behavior toward nicotine-related pictures in smokers or non-smokers. Our findings indicate that the AAT is suited for measuring smoking-related approach tendencies in smokers. Furthermore, we provide evidence for a diminished approach tendency toward food-related stimuli in smokers, suggesting a decreased sensitivity to natural rewards in the course of nicotine addiction. Our results indicate that in contrast to similar studies conducted in alcohol, cannabis and heroin users, the AAT might only be partially suited for measuring smoking-related approach

    Full Text Available Abstract Background Many smokers believe that "light" cigarettes are less harmful than regular cigarettes, which is at variance with the scientific evidence. The Framework Convention on Tobacco Control (FCTC aims to address this problem in Article 11 which deals with misleading labelling of tobacco products. In this study we aimed to determine smokers' use and beliefs concerning "light" and "mild" cigarettes ("lights", including in relation to ethnicity, deprivation and other socio-demographic characteristics. Methods The New Zealand (NZ arm of the International Tobacco Control Policy Evaluation Survey (ITC Project uses as its sampling frame the NZ Health Survey. This is a national sample with boosted sampling of Maori, Pacific peoples and Asians. From this sample we surveyed adult smokers (n = 1376 about use and beliefs relating to "light" cigarettes. We assessed the associations with smoking "lights" after adjusting for socio-demographic variables, and smoking-related behaviours and beliefs. Results Many smokers of "lights" believed that smoking "lights" made it easier to quit smoking (25%, that "lights" are less harmful (42%, and that smokers of "lights" take in less tar (43%. Overall most "lights" smokers (60% had at least one of these three beliefs, a proportion significantly higher than for smokers of "regular" cigarettes at 45% (adjusted odds ratio (aOR = 1.96, 95% CI = 1.29 – 2.96. While "lights" smokers had significantly lower tobacco consumption and were more aware of smoking harms, they were no more likely to be intending to quit or have made a previous quit attempt. By ethnicity, both Maori and Pacific people were less likely to smoke "lights" than Europeans (aOR = 0.53, 95% CI = 0.35 – 0.80 and aOR = 0.14, 95% CI = 0.05 – 0.40 respectively. In contrast there was no significant difference by level of deprivation. Roll-your-own (RYO tobacco smokers were less likely to smoke "light" forms of RYO tobacco while both older and women

    Empirical evidence supporting the interplay between pain intensity and tobacco smoking has been growing. The current investigation advances this work in three important ways: (1) controlling for negative affectivity and gender; (2) examining pain intensity in smokers from a community sample, rather than specialized pain treatment centers; and, (3) studying smokers who are highly motivated to quit. Participants were adult smokers (N=112; 35% female; Mage=41.4, SD=13.1) participating in a larger study examining barriers to cessation during a self-guided quit attempt. At baseline, participants completed self-report measures on pain intensity and smoking severity outcomes. As hypothesized, more intense pain was significantly associated with all four smoking severity variables: years as a daily smoker, current cigarettes per day, cigarettes per day during the heaviest lifetime smoking period, and current level of nicotine dependence. These associations remained when taking into account the variance accounted for by gender and negative affectivity. These data provide evidence that more intense pain is related to more severe smoking behavior and nicotine dependence. Pain reduction could be an important target in regard to smokers with chronic pain.

    2007-04-01

    Full Text Available IntroductionFor the past 20 years, there have been no changes to the text-only cigarette warning labels in the United States. During this same time period, other countries placed large graphic warning labels on cigarette packages. The purpose of this study was to investigate the reactions of U.S. young adult smokers and nonsmokers aged 18 to 24 years to Canadian cigarette label text and graphic warnings. The study focused on determining their perceptions and the potential impact of Canadian labels on smoking, and study participants were asked for suggestions for modifications of U.S. cigarette warning labels so they would be effective for smoking deterrence and cessation.Methods During January and February 2002, 11 focus groups consisting of 54 smokers and 41 nonsmokers were conducted in the Detroit metropolitan area. Current smokers were defined as those who had smoked a cigarette within the past 30 days. Participants were asked about their knowledge and perceptions of current U.S. cigarette warning labels and their impressions of Canadian cigarette warning labels.AnalysisA content analysis and a word index were applied to the transcripts of all focus groups to identify and clarify themes and domains that appeared in group discussions and to compare results across different groups.ResultsFocus group participants reported that Canadian cigarette warning labels were more visible and informative than U.S. cigarette warning labels. Messages perceived to be relevant to smokers were considered effective. Education level did not appear related to how participants responded to warning labels. There were some differences for warning labels that had sex-specific messages.DiscussionWarning labels are one component of comprehensive tobacco control and smoking cessation efforts. Stronger warnings on cigarette packages need to be part of a larger U.S. public health educational effort.

    Background: The “Valentino” cross-sectional study is aimed at evaluating the prevalence and pattern of cigarette smoking according to occupational group in a representative sample of workers aged 18-35 years from Abruzzo, Italy.

    Methods: Randomly selected workers anonymously self-compiled a structured questionnaire containing validated items. Job type was coded according to the International Standard Classification of Occupations.

    Results: The sample consisted of 3989 workers. Current smoking prevalence was 45.9%, varying across occupational groups and ranged from 37.2% among clerical support workers, up to 57.1% among craft, agricultural and fishery sector workers. After controlling for several potential confounders using logistic regression, craft, agricultural, forestry and fishery workers (adjusted odds ratio 1.65; 95%confidence intervals 1.21-2.27, and call-center operators (1.91; 1.44-2.53 were significantly more likely to be current smokers than professionals and clerical or support workers. Interestingly, when alcohol and cannabis use were included in multivariate analysis, the association between smoking and gender was no longer significant.

    Conclusions: An independent association was found between specific occupational classes and tobacco smoking, suggesting occupation type should be considered in prioritizing subsets of populations towards which smoking cessation campaigns should be targeted first.

    With attention to the rapidly growing market of electronic nicotine delivery systems (ENDS/e-cigarettes) and the fastest growing US ethnic minority group, the current study explored associations between awareness, perceived risks, and use of ENDS among Asian American and Pacific Islander (AAPI) young adults. AAPI young adults (ages 18-25) in California were recruited via social media, college classes, listservs for AAPI-serving non-profits, and snowball sampling to complete an anonymous survey between 2014 and 2015. The sample (N = 501) was 57% women, 15% LGBTQIA; with a mean age of 21; 26% foreign-born; identifying as Filipino (29%), Chinese (24%), Vietnamese (14%), mixed-AAPI heritage (13%), or 21% other. Nearly half the sample (44%) reported ever ENDS use; 11% were current users. Current ENDS use was twofold greater for: Filipino and Vietnamese compared to Chinese respondents; men versus women; LGBTQIA-identified respondents; those vocationally trained; and employed. Awareness of ENDS from peers/friends was most common and was associated with ever though not current ENDS use. Most respondents perceived ENDS as harmful (62%); low compared to high risk perception was associated with a three-fold greater likelihood of ever use and six-fold greater likelihood of current use. Popular flavors were fruit (49%, e.g., lychee, taro) and candy/sweets (26%). Current users viewed ENDS as a healthier alternative or quit aid for conventional cigarettes (42%); recreation/social use (33%) also was common. Findings indicate ENDS visibility among AAPI young adults in California with affinity for flavors and many engaging in trial and current use for harm reduction and recreational/social aims.

    The average retail price per pack of cigarettes is less than $6, which is substantially lower than the $10 per-pack target established in 2014 by the Surgeon General to reduce the smoking rate. We estimated the impact of three cigarette pricing scenarios on smoking prevalence among teens aged 12-17 years, young adults aged 18-25 years, and adults aged ≥26 years, by state: (1) $0.94 federal tax increase on cigarettes, as proposed in the fiscal year 2017 President's budget; (2) $10 per-pack retail price, allowing discounts; and (3) $10 per-pack retail price, eliminating discounts. We conducted Monte Carlo simulations to generate point estimates of reductions in cigarette smoking prevalence by state. We found that each price scenario would substantially reduce cigarette smoking prevalence. A $10 per-pack retail price eliminating discounts could result in 637,270 fewer smokers aged 12-17 years; 4,186,954 fewer smokers aged 18-25 years; and 7,722,460 fewer smokers aged ≥26 years. Raising cigarette prices and eliminating discounts could substantially reduce cigarette smoking prevalence as well as smoking-related death and disease. PMID:27453597

Evaluation of biomarkers of biological effect (e.g. inflammation, lipids, hypercoaguable state) indicated that the majority of consistent and statistically significant improvements over time within each group were observed in markers of inflammation. Consistent and statistically significant differences in pairwise comparisons between product groups were not observed. These findings are relevant to the understanding of biomarkers of biological effect related to cigarette smoking as well as the risk continuum across various tobacco products (ClinicalTrials.gov Identifier: NCT02061917).

    Objective: To assess the impact of promotions on cigarette sales in Taiwan after the cigarette market opened to foreign companies, and to assess whether young smokers were targeted by these companies. Methods: Trends in cigarette sales, advertising expenditure, brand preference, and cigarette consumption were examined for the period following the 1987 opening of the cigarette market. Tobacco industry internal documents from Legacy Tobacco Documents Library of the University of California, San Francisco, were searched for corporate strategies on promoting youth consumption in Taiwan. Results: Between 1995 and 2000, the inflation adjusted advertising expenditures by all foreign firms increased fourfold. Much of the expenditure was spent on brand stretching the Mild Seven (Japan) and Davidoff (Germany) brands in television advertising. By 2000, the market share of foreign cigarettes exceeded domestics by three to one among young smokers and the leading brand preferred by this segment shifted from the most popular domestic brand (Long Life) to a foreign brand (Mild Seven). Furthermore, there was a sudden increase of 16.4% in smoking rates among young adults (from 36.1% to 42.0%) during the first five years after the market opened. This was also accompanied by increased per capita cigarette consumption and decreased age of smoking initiation. Industry documents confirmed the use of strategies targeted at the young. In particular, establishing new point of sale (POS) retail stores or promotional activities at POS were found to be more effective than advertising in magazines. Conclusions: This study provides evidence that advertising increased with increased competition following the market opening, which, in turn, spurred cigarette sales and consumption.

    Full Text Available OBJECTIVE: This comparison of population-based representative samples of adult smokers in Canada (n=1 751 and Mexico (n=1 081 aimed to determine whether cigarette packages with graphic warning labels in Canada had a stronger impact than the text-only warning labels in Mexico. MATERIALS AND METHODS: Bivariate and multivariate adjusted models were used in this study. Results. Canadian smokers reported higher warning label salience (i.e., noticing labels & processing label messages than Mexican smokers, and warning label salience independently predicted intention to quit. Moreover, Canadians had higher levels of knowledge about smoking-related health outcomes that were included as content on Canadian, but not Mexican, warning labels. Finally, a majority of Mexican smokers want their cigarette packs to contain more information than they currently contain. DISCUSSION: These results are consistent with other studies that indicate that cigarette packages whose warning labels contain prominent graphic imagery are more likely than text-only warning labels to promote smoking-related knowledge and smoking cessation.OBJETIVO: Esta comparación basada en muestras representativas de la población de fumadores adultos de Canadá (n = 1 751 y México (n = 1 081 pretendió determinar si las cajetillas de cigarrillos con leyendas de advertencia que contienen imágenes gráficas en Canadá tuvieron un impacto más acentuado que las leyendas mexicanas que se basan sólo en textos.

MATERIALS AND METHODS: Cross-sectional survey of a representative sample of 1 765 adult smokers from Guadalajara, Mexico, 2010. Logistic regression models were estimated to determine the association between recall of having purchased a pack with a pictorial HWL and psychosocial variables indicating their impact. RESULTS: 58% reported having purchased a pack with one of the pictorial HWLs, and these were considered the exposed population. Exposed smokers reported a greater frequency of thinking about smoking-related risks (34 vs. 25% p=0.003, and thinking about quitting smoking (23 vs. 14% p=0.001. Exposure to pictorial HWLs was also associated with a greater acceptability of HWLs as a means of communicating with smokers (93 vs. 87% p<0.001, as was the perception that the government communicates well about tobacco-related health risks (68 vs. 55% p<0.001. CONCLUSION: Pictorial HWLs have made smokers think more about these risks and about quitting smoking. This policy should continue to be exploited as a cost-effective educational intervention.

    Results: Response rate was 98%. Prevalence of cigarette smoking was 9.7%. Among cigarette users, 12.6% reported smoking 2 years. Almost half of those surveyed (48.9% smoked 20 cpd. Almost a quarter (20.4% of the cigarette smokers tried to quit in the past year. Being male, married, aged 37-54, having higher perceived levels of stress, a non-manual occupation, and sedentary lifestyle were positively associated with cigarette smoking. Manual labor occupations, housewife/jobless status, and going frequently to restaurants were positive predictors of hookah smoking. Conclusions: Compared to cigarettes, hookah smoking was more prevalent among Iranian adults. Approximately, the prevalence of hookah smoking in women is the same as men, whereas cigarette use was 31 times more common in men. Cigarette and hookah smoking were associated with less healthy lifestyle habits in both men and women.

  17. Smokers' strategic responses to sin taxes: evidence from panel data in Thailand.

    White, Justin S; Ross, Hana

    2015-02-01

    In addition to quitting and cutting consumption, smokers faced with higher cigarette prices may compensate in several ways that mute the health impact of cigarette taxes. This study examines three price avoidance strategies among adult male smokers in Thailand: trading down to a lower-priced brand, buying individual sticks of cigarettes instead of packs, and substituting roll-your-own tobacco for factory-manufactured cigarettes. Using two panels of microlevel data from the International Tobacco Control Southeast Asia Study, collected in 2005 and 2006, we estimate the effects of a substantial excise tax increase implemented throughout Thailand in December 2005. We present estimates of the marginal effects and price elasticities for each of five consumer behaviors. We find that, controlling for baseline smoking characteristics, sociodemographics, and policy variables, quitting is highly sensitive to changes in cigarette prices, but so are brand choice, stick-buying, and use of roll-your-own tobacco. Neglecting such strategic responses leads to overestimates of a sin tax's health impact, and neglecting product substitution distorts estimates of the price elasticity of cigarette demand. We discuss the implications for consumer welfare and several policies that mitigate the adverse impact of consumer responses. PMID:24677731

    Full Text Available Timed-pregnant C57BL/6J mice were exposed to 2.4% nicotine in propylene glycol (PG or 0% nicotine /PG once a day from gestational day 15 until delivery. After delivery, offspring and mothers were exposed to E-cigarette vapors for an additional 14 days from postnatal day 2 through 16. Following their last exposure serum cotinine levels were measured in female juvenile mice. Male mice underwent behavioral testing at 14 weeks of age to assess sensorimotor, affective, and cognitive functional domains.Adult male mice exposed to 2.4% nicotine/PG E-cigarette vapors had significantly more head dips in the zero maze test and higher levels of rearing activity in the open field test compared to 0% nicotine/PG exposed mice and untreated controls. In the water maze test after reversal training, the 2.4% nicotine/PG mice spent more than 25% of time in the new location whereas the other groups did not.Adult male mice exhibited increased levels of activity in the zero maze and open field tests when exposed to E-cigarette vapor containing nicotine during late prenatal and early postnatal life. These findings indicate that nicotine exposure from E-cigarettes may cause persistent behavioral changes when exposure occurs during a period of rapid brain growth.

    Kelly L Kandra

    Full Text Available Electronic cigarettes (e-cigarettes are not currently approved or recommended by the Food and Drug Administration (FDA or various medical organizations; yet, they appear to play a substantial role in tobacco users' cessation attempts. This study reports on a physician survey that measured beliefs, attitudes, and behavior related to e-cigarettes and smoking cessation. To our knowledge this is the first study to measure attitudes toward e-cigarettes among physicians treating adult smokers.Using a direct marketing company, a random sample of 787 North Carolina physicians were contacted in 2013 through email, with 413 opening the email and 128 responding (response rate = 31%. Physicians' attitudes towards e-cigarettes were measured through a series of close-ended questions. Recommending e-cigarettes to patients served as the outcome variable for a logistic regression analysis.Two thirds (67% of the surveyed physicians indicated e-cigarettes are a helpful aid for smoking cessation, and 35% recommended them to their patients. Physicians were more likely to recommend e-cigarettes when their patients asked about them or when the physician believed e-cigarettes were safer than smoking standard cigarettes.Many North Carolina physicians are having conversations about e-cigarettes with their patients, and some are recommending them. Future FDA regulation of e-cigarettes may help provide evidence-based guidance to physicians about e-cigarettes and will help ensure that patients receive evidence-based recommendations about the safety and efficacy of e-cigarettes in tobacco cessation.

    2014-10-01

    Full Text Available The electronic nicotine delivery system, also known as the electronic cigarette, is generating considerable controversy, not only in the general population but also among health professionals. Smokers the world over have been increasingly using electronic cigarettes as an aid to smoking cessation and as a substitute for conventional cigarettes. There are few available data regarding the safety of electronic cigarettes. There is as yet no evidence that electronic cigarettes are effective in treating nicotine addiction. Some smokers have reported using electronic cigarettes for over a year, often combined with conventional cigarettes, thus prolonging nicotine addiction. In addition, the increasing use of electronic cigarettes by adolescents is a cause for concern. The objective of this study was to describe electronic cigarettes and their components, as well as to review the literature regarding their safety; their impact on smoking initiation and smoking cessation; and regulatory issues related to their use.

    Full Text Available Tobacco use is inextricably linked to a number of health risks both in the general and HIV-infected populations. There is, however, a dearth of research on effective tobacco control programs among people living with HIV, and especially among adolescents, young adults and pregnant women, groups with heightened or increased vulnerability secondary to tobacco use. Adolescents and young adults constitute a growing population of persons living with HIV infection. Early and continued tobacco use in this population living with a disease characterized by premature onset multimorbidity and chronic inflammation is of concern. Additionally, there is an increased acuity for tobacco control among HIV-infected pregnant women to reduce pregnancy morbidity and improve fetal outcome. This review will provide an important summary of current knowledge of tobacco use among HIV-infected adolescents, young adults and pregnant women. The effects of tobacco use in these specific populations will be presented and the current state of tobacco control within these populations, assessed.

    Full Text Available Background: Global Adult Tobacco Survey (GATS, Malaysia 2011 reported that the prevalence of smoking was highest among Malays male i.e., 24.6% (CI:22.1,27.3. The aim of this study was to evaluate the perception of a group of smokers towards various national anti-smoking initiatives as well as its association with age and education level.Methods: The study was conducted in a randomly selected pre-dominantly Malay settlement in Malaysia using a validated self-administered questionnaire. The national anti-smoking initiatives assessed were ‘anti-smoking campaign’, ‘labelling on cigarette pack’, ‘increment of cigarette price’, ‘smoke free zone policies’ and ‘Quit smoking clinic’ initiatives.Results: A total of 136 Malay male smokers participated in this study. The percentage of respondents agreeing with the questions asked were very low, ranging from only 5.9% to 24.3%, except for one i.e., 99.3% agreed that the information on cigarette packs can be trusted. Assessing the success of various types of national anti-smoking initiatives in helping smokers to quit, the percentage of those who agreed ranged between 17.6% - 24.3% and in helping to reduce numbers of cigarette smoked, the range was from 12.5% to 18.4%. There was a significant association between ‘increment of cigarette price’ initiative with level of education (P=0.02.Conclusion: The percentage of positive perceptions towards all anti-smoking efforts was low and perception towards ‘increment of cigarette price’ was associated with level of education. Keywords: Perception, Anti-smoking initiatives, Malaysia

  12. [The challenge of electronic cigarettes].

    Córdoba García, Rodrigo

    2014-01-01

    The electronic cigarette (e-cig) is a device with a conventional cigarette shape that releases a determined dose of nicotine vapour through an electronic heating process. The nicotine cartridges vary significantly in the amount of nicotine released, even within the same brand. Not all brands admit that they contain nicotine, but this is detected in the majority of units analysed. The e-cig usually contains a propellant, such as propylene glycol, which is a lung irritant. The short-term respiratory effect of the vapour of an e-cig is similar to that caused by the smoke of a cigarette, and is a cause of broncho-restriction. The majority of brands contain glycerine and at least one case of lipoid pneumonia has been detected due to this substance. Many brands contain traces of N-nitrosamines, heavy metals, and other products that are found in conventional cigarette smoke, but in a much higher proportion. There is currently no scientific evidence available that shows it is an effective device for quitting smoking, thus it should not be pro-actively recommended for this purpose, and may interfere with the use of demonstrated scientific evidence-based treatments for quitting smoking. It may have an undesirable effect on promoting the starting of smoking in adolescents or keeping adult smokers consuming nicotine and on gestural dependency. The toxicity of the vapour is not well known, but it is known that they are not innocuous, thus they should not be used in closed public spaces. PMID:24704194

    Full Text Available Context: In India, 14% of the population use smoked tobacco products. Increasing prices of these products is one of the measures to curb their consumption. Aims: This study analyzes "unit price" and "daily consumption" of cigarettes and bidis and investigates their relation with each other. Settings And Design: A cross-sectional survey was conducted in four states of India (Bihar, West Bengal, Madhya Pradesh and Maharashtra as a part of the International Tobacco Control Policy (TCP Evaluation Project (the TCP India Project during 2010-2011. Methods: Information was collected from adult (aged ≥15 daily exclusive smokers of cigarette/bidi regarding (a last purchase (purchase in pack/loose, brand and price and (b daily consumption. Average unit price and daily consumption was calculated for different brands and states. Regression model was used to assess the impact of price on daily consumption. Results: Bidis were much less expensive (₹0.39 than cigarettes (₹3.1. The daily consumption was higher (14 among bidi smokers than cigarette smokers (8. The prices and daily consumption of bidis (₹0.33-0.43; 12-15 and cigarettes (₹2.9-3.6; 5-9 varied across the four states. The unit prices of bidis and cigarettes did not influence their daily consumption. Smokers purchasing bidis in packs paid substantially less per unit and purchase of bidis and cigarettes in packs influenced their consumption positively. Conclusions: Cigarettes although more expensive than bidis, seem very cheap if compared internationally. Hence, prices of both cigarettes and bidis do not influence their consumption.

    2015-02-01

    Twelve focus groups in Glasgow (Scotland) were conducted with female non-smokers and occasional smokers aged 12-24 years (N = 75), with each group shown 11 cigarettes: two (standard) cigarettes with cork filters; two coloured cigarettes (pink or brown); four slim cigarettes; an aromatized black cigarette; a menthol cigarette and a cigarette with a flavour-changing rupturable capsule in the filter. Participants were asked to rank the cigarettes by appeal, taste and harm. The capsule cigarette was then discussed in depth. The pink coloured cigarette and slim cigarettes created significant interest and were generally perceived as most appealing and pleasant tasting, and least harmful. The black aromatized cigarette received a mixed response, with some disliking the dark colour and associating it with low appeal, strong taste and increased harm, whereas for others the smell helped to enhance appeal and taste perceptions and lower perceptions of harm. The novel capsule cigarette, when discussed in-depth, was viewed very positively. Just as research shows that cigarette packs can influence perceptions of appeal, harm and taste, this study suggests that the actual cigarettes can do likewise. The findings have implications for tobacco education and policy.

  17. Socioeconomic Differences in the Effectiveness of the Removal of the “Light” Descriptor on Cigarette Packs: Findings from the International Tobacco Control (ITC Thailand Survey

    Directory of Open Access Journals (Sweden)

    Charamporn Holumyong

    2011-06-01

    Full Text Available Many smokers incorrectly believe that “light” cigarettes are less harmful than regular cigarettes. To address this problem, many countries have banned “light” or “mild” brand descriptors on cigarette packs. Our objective was to assess whether beliefs about “light” cigarettes changed following the 2007 removal of these brand descriptors in Thailand and, if a change occurred, the extent to which it differed by socioeconomic status. Data were from waves 2 (2006, 3 (2008, and 4 (2009 of the International Tobacco Control (ITC Thailand Survey of adult smokers in Thailand. The results showed that, following the introduction of the ban, there was an overall decline in the two beliefs that “light” cigarettes are less harmful and smoother than regular cigarettes. The decline in the “less harmful” belief was considerably steeper in lower income and education groups. However, there was no evidence that the rate of decline in the “smoother” belief varied by income or education. Removing the “light” brand descriptor from cigarette packs should thus be viewed not only as a means to address the problem of smokers’ incorrect beliefs about “light” cigarettes, but also as a factor that can potentially reduce socioeconomic disparities in smoking-related misconceptions.

Method: Data were obtained, in 1999, through application and analysis of a questionnaire, based on the model proposed by WHO, among 333 physicians of whom 213 (64% were men and 120 (36% were women. The average age of the sample was 43 (± 10.5 years with 65.1% between 30 and 50 years. Results: Smoking prevalence was 18.3% (15.9% regular smokers and 2.4% occasional smokers. Regular smoking prevalence was 17.8% among males and 12.5% among females, with no significant statistic difference (p > 0.05. The mean number of cigarettes smoked was 24.3 packets/years, being superior among men and increasing with age. It was verified that 86.8% of the smokers began smoking before 20 years of age, due to their desire or friends' influence in 63.2% of the cases. Conclusion: Although smoking prevalence among Rio Grande physicians is lower than in other countries, it is still unacceptable. Since this class has a decisive role in the prevention and fight against smoking, a specific campaign against tobacco among these professionals would greatly justify.

    The effect of raising cigarette taxes to reduce smoking has been the subject of several studies, which often treat the price of cigarettes as an exogenous factor given to smokers who respond to it by adjusting their smoking behavior. However, cigarette prices vary with brand and quality, and smokers can and do switch to lower-priced brands to reduce the impact of the tax on the cost of cigarettes as they try to consume the same number of cigarettes as they had before a tax hike. Using data from a two-year follow-up interview survey conducted before and after a new cigarette tax scheme was imposed in Taiwan in 2002, this study examines three behavioral changes smokers may make to respond to tax-induced cigarette price increase: brand-switching, amount consumed, and amount spent on smoking. These changes were studied in relation to smoker income, before-tax cigarette price, level of addiction, exposure to advertizing, and consumer loyalty. We found that smokers, depending upon exposure to advertizing, level of consumer loyalty and initial price of cigarettes, switched brands to maintain current smoking habits and control costs. We also found that the initial amount smoked and level of addiction, not price, at least not at the current levels in Taiwan, determined whether a smoker reduced the number of cigarettes he consumed.

    Quitting smoking benefits older individuals, yet few recent studies have described older smokers. The goal of this paper was to test a series of hypotheses about differences between smokers aged 50 years or older (50+) and those younger than age 50 (<50) presenting to the same treatment facility during 2002-2004 for participation in two randomized clinical trials: one exclusively for smokers aged 50+, and a second open to smokers aged 18 or older. As predicted, smokers aged 50+ were more tobacco dependent, had better psychological functioning, and had poorer physical functioning than those aged <50. Contrary to predictions, we found no differences in motivation to quit cigarette smoking or in alcohol use. Women aged 50+ were less likely to report marijuana use than women aged <50, and less likely than men to receive a positive diagnosis for alcohol abuse. Despite higher scores on measures of tobacco dependence, older smokers were less likely to be diagnosed as tobacco dependent or as having tobacco withdrawal using DSM-IV criteria. Rates of DSM-IV alcohol abuse and dependence were high in both age groups but were higher for smokers aged <50. We found no striking differences between studies in reasons for exclusion, but in both the proportion of individuals excluded due to current antidepressant use was high. Implications for the assessment and treatment of older adults are discussed. PMID:18324565

    Full Text Available Abstract Background Very few studies have evaluated the adverse effect of passive smoking exposure among active smokers, probably due to the unproven assumption that the dose of toxic compounds that a smoker inhales by passive smoke is negligible compared to the dose inhaled by active smoke. Methods In a controlled situation of indoor active smoking, we compared daily benzo(apyrene (BaP dose, estimated to be inhaled by smokers due to the mainstream (MS of cigarettes they have smoked, to the measured environmental tobacco smoke (ETS they inhaled in an indoor environment. For this aim, we re-examined our previous study on daily personal exposure to BaP of thirty newsagents, according to their smoking habits. Results Daily BaP dose due to indoor environmental contamination measured inside newsstands (traffic emission and ETS produced by smoker newsagents was linearly correlated (p = 0.001 R2 = 0.62 with estimated BaP dose from MS of daily smoked cigarettes. In smoker subjects, the percentage of BaP daily dose due to ETS, in comparison to mainstream dose due to smoked cigarettes, was estimated with 95% confidence interval, between 14.6% and 23% for full flavour cigarettes and between 21% and 34% for full flavour light cigarettes. Conclusions During indoor smoking, ETS contribution to total BaP dose of the same smoker, may be not negligible. Therefore both active and passive smoking exposures should be considered in studies about health of active smokers.

    Full Text Available Current smokers who are prescribed home oxygen may not benefit from the therapy. In addition to being an obvious fire hazard, there is some evidence that the physiological mechanisms by which home oxygen is believed to operate are inhibited by smoking. Although their effectiveness is yet to be demonstrated, electronic cigarettes (e-cigarettes are often regarded as an aid to smoking cessation. However, several burn accidents in e-cigarette smokers receiving home oxygen therapy have also been reported, leading Health Canada to release a warning of fire risk to oxygen therapy patients from e-cigarettes. It is the authors’ position that patients receiving oxygen should definitely not use e-cigarettes. The authors provide suggestions for addressing the delicate issue of home oxygen therapy in current cigarette and/or e-cigarette smokers.

    This study was conducted to evaluate the effects of e-cigarette refill liquid administration alone or with nicotine on the antioxidant defense status, functional and histopathological changes in adult rat liver tissue. For this purpose, 32 rats were treated for 28 days as follows: control group was injected intra-peritoneally with physiological saline; e-cigarette 0% treated group received an intra-peritoneal injection of e-liquid without nicotine diluted in physiological saline, e-cigarette-treated group received an intra-peritoneal injection of e-liquid containing 0.5 mg of nicotine/kg of body weight/day diluted in physiological saline and nicotine-treated group received an intra-peritoneal injection of 0.5 mg of nicotine/kg of body weight/day diluted in physiological saline. In e-liquid without nicotine-exposed group, activities of the liver biomarkers aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and lactate dehydrogenase increase. Interestingly, oxidative stress indicators showed decreased total protein content, associated with a reduction in the antioxidant enzymes activities superoxide dismutase, catalase and glutathione-S-transferase, and an elevation in malondialdehyde content, highlighting the promotion of lipid peroxidation and oxidative stress. Histological studies identified inflammatory cells infiltration and cell death. Thus, e-liquid seems to promote oxidative tissue injuries, which in turn lead to the observed histopathological finding. In comparison, nicotine alone induced less oxidative stress and less histopathological disorders, whereas e-liquid with nicotine gave rise to more histopathological injuries. Thereby, e-liquid, per se, is able to induce hepatotoxicity and supplementation with nicotine worsens this state.

    Full Text Available Background: In recent years, electronic cigarettes (e-cigarettes have generated considerable interest and debate on the implications for tobacco control and public health. Although the rapid growth of e-cigarettes is global, at present, little is known about awareness and use. This paper presents self-reported awareness, trial and current use of e-cigarettes in 10 countries surveyed between 2009 and 2013; for six of these countries, we present the first data on e-cigarettes from probability samples of adult smokers. Methods: A cross-sectional analysis of probability samples of adult (≥ 18 years current and former smokers participating in the International Tobacco Control (ITC surveys from 10 countries. Surveys were administered either via phone, face-to-face interviews, or the web. Survey questions included sociodemographic and smoking-related variables, and questions about e-cigarette awareness, trial and current use. Results: There was considerable cross-country variation by year of data collection and for awareness of e-cigarettes (Netherlands (2013: 88%, Republic of Korea (2010: 79%, United States (2010: 73%, Australia (2013: 66%, Malaysia (2011: 62%, United Kingdom (2010: 54%, Canada (2010: 40%, Brazil (2013: 35%, Mexico (2012: 34%, and China (2009: 31%, in self-reports of ever having tried e-cigarettes (Australia, (20%, Malaysia (19%, Netherlands (18%, United States (15%, Republic of Korea (11%, United Kingdom (10%, Mexico (4%, Canada (4%, Brazil (3%, and China (2%, and in current use (Malaysia (14%, Republic of Korea (7%, Australia (7%, United States (6%, United Kingdom (4%, Netherlands (3%, Canada (1%, and China (0.05%. Conclusions: The cross-country variability in awareness, trial, and current use of e-cigarettes is likely due to a confluence of country-specific market factors, tobacco control policies and regulations (e.g., the legal status of e-cigarettes and nicotine, and the survey timing along the trajectory of e-cigarette

    Previous researchers have argued that the social market for cigarettes insulates its participants from policies designed to curb youth smoking. Using state Youth Risk Behavior Survey data, we examine whether recent changes in state cigarette taxes affected how young smokers obtained their cigarettes. Our estimates suggest that tax increases reduce youth smoking participation primarily through their effect on third-party purchase, although there is evidence that they are negatively related to ...

    We examine differences between college students and non-students with respect to orientation toward e-cigarettes. Participants were U.S. adults 18-24 (465 students, 409 non-students). Data collection employed an online survey by GfK Custom Research. Smoking, vaping, and use of alternate tobacco were assessed, as were variables from the Theory of Reasoned Action and Diffusion of Innovations. This study showed that smoking status largely explains use and orientation toward electronic cigarettes among both students and non-students, with differences attributable to higher smoking rates among non-students. Results also showed that among student smokers there was a greater level of information exposure concerning electronic cigarettes, and more prevalence in the use of alternate tobacco. Hookah use in that group was significantly greater than for non-student smokers. Together these findings suggest that students may be more vulnerable to electronic cigarette use due to higher related information exposure and the integration of vaping into hookah culture. Significance for public health This is the first study that we are aware of that looks specifically at the differences between college students’ and non-students’ behaviours and attitudes toward electronic cigarettes. A critical concern for young adults is whether adoption of electronic cigarettes will eventually lead to adoption of tobacco use. In this study we find that differences between student and non-student groups can be largely accounted for by smoking status. However, students may be more vulnerable to electronic cigarette use due to higher related-information exposure and the integration of vaping into hookah culture. PMID:27747198

    Although nicotine addiction is characterized by both structural and functional abnormalities in brain networks involved in salience and cognitive control, few studies have integrated these data to understand how these abnormalities may support addiction. This study aimed to (1) evaluate gray matter density and functional connectivity of the anterior insula in cigarette smokers and never smokers and (2) characterize how differences in these measures were related to smoking behavior. We compared structural magnetic resonance imaging (MRI) (gray matter density via voxel-based morphometry) and seed-based functional connectivity MRI data in 16 minimally deprived smokers and 16 matched never smokers. Compared with controls, smokers had lower gray matter density in left anterior insula extending into inferior frontal and temporal cortex. Gray matter density in this region was inversely correlated with cigarettes smoked per day. Smokers exhibited negative functional connectivity (anti-correlation) between the anterior insula and regions involved in cognitive control (left lPFC) and semantic processing/emotion regulation (lateral temporal cortex), whereas controls exhibited positive connectivity between these regions. There were differences in the anterior insula, a central region in the brain's salience network, when comparing both volumetric and functional connectivity data between cigarette smokers and never smokers. Volumetric data, but not the functional connectivity data, were also associated with an aspect of smoking behavior (daily cigarettes smoked). PMID:25990865

    Tobacco use is a leading preventable cause of morbidity and mortality, with nearly 6 million deaths caused by tobacco use worldwide every year (1). Cigarette smoking is the most common form of tobacco use in most countries, and the majority of adult smokers initiate smoking before age 18 years (2,3). Limiting access to cigarettes among youths is an effective strategy to curb the tobacco epidemic by preventing smoking initiation and reducing the number of new smokers (3,4). CDC used the Global Youth Tobacco Survey (GYTS) data from 45 countries to examine the prevalence of current cigarette smoking, purchase of cigarettes from retail outlets, and type of cigarette purchases made among school students aged 13-15 years. The results are presented by the six World Health Organization (WHO) regions: African Region (AFR); Eastern Mediterranean Region (EMR); European Region (EUR); Region of the Americas (AMR); South-East Asian Region (SEAR); and Western Pacific Region (WPR). Across all 45 countries, the median overall current cigarette smoking prevalence among students aged 13-15 years was 6.8% (range = 1.7% [Kazakhstan]-28.9% [Timor-Leste]); the median prevalence among boys was 9.7% (2.0% [Kazakhstan]-53.5% [Timor-Leste]), and among girls was 3.5% (0.0% [Bangladesh]-26.3% [Italy]). The proportion of current cigarette smokers aged 13-15 years who reported purchasing cigarettes from a retail outlet such as a store, street vendor, or kiosk during the past 30 days ranged from 14.9% [Latvia] to 95.1% [Montenegro], and in approximately half the countries, exceeded 50%. In the majority of countries assessed in AFR and SEAR, approximately 40% of cigarette smokers aged 13-15 years reported purchasing individual cigarettes. Approximately half of smokers in all but one country assessed in EUR reported purchasing cigarettes in packs. These findings could be used by countries to inform tobacco control strategies in the retail environment to reduce and prevent marketing and sales of

    Full Text Available OBJECTIVE: The growing consensus on the negative impact of cigarette smoking on fertility prompted us to compare the rate of sperm respiration in smokers and non-smokers. MATERIALS AND METHODS: Semen samples from 20 smokers and 58 non-smokers consulting at the andrology laboratory for fertility evaluation were used. Smoking was defined as consumption of at least a half a pack per day. A phosphorescence analyzer that measures O2 concentration in sperm suspensions as function of time was used to determine the rate of respiration. In a sealed vial, the rate of sperm respiration (k was defined as -d[O2]/dt; where [O2] was obtained from the phosphorescence decay rate of a palladium phosphor. [O2] in solutions containing sperm and glucose declined linearly with time, showing the kinetics of O2 consumption was zero-order. Inhibition of O2 consumption by cyanide confirmed the oxidations that occurred in the sperm mitochondrial respiratory chain. RESULTS: There were no differences (p > 0.28 between smokers and non-smokers for ejaculate volume, motility, concentration, normal morphology, viability and hypo-osmotic swelling test. The rate (mean ± SD, in µM O2/min/108 sperm of sperm mitochondrial O2 consumption in the smokers was 0.96 ± 0.58 and in the non-smokers 1.39 ± 0.67 (p = 0.004. CONCLUSIONS: The rate of sperm respiration was significantly lower in smokers. This negative impact of cigarette smoking on sperm aerobic metabolism may, in part, explain the lower rate of fertility in smokers.

    Objectives Smoking prevalence is slow to reduce among Indigenous Australians of reproductive age. We analysed the relationships between age of smoking initiation, recalled initiation influences and self-assessment of smoking risks in Aboriginal smokers. Design, setting and participants A community-based cross-sectional survey of Aboriginal smokers aged 18–45 years (N=121; 58 men) was undertaken, using single-item measures. The Smoking Risk Assessment Target (SRAT) as the primary outcome measure enabled self-assessment of smoking risks from 12 options, recategorised into 3 groups. Participants recalled influences on their smoking initiation. Multinomial logistic regression modelling included age, gender, strength of urges to smoke, age at initiation (regular uptake) and statistically significant initiation influences on χ2 tests (‘to be cool’, alcohol and cannabis). Results Frequent initiation influences included friends (74%; SD 0.44), family (57%; SD 0.5) and alcohol (40%; SD 0.49). 54% (n=65) of smokers had the highest risk perception on the SRAT, selected by those who cared about the smoking risks and intended to quit soon. On multivariate analyses, compared with the highest level of SRAT, male gender, lower age of uptake and strong urges to smoke were significantly associated with the lowest level of SRAT, selected by those who refuted risks or thought they could not quit. Lower age of uptake and alcohol were associated with mid-level of SRAT, selected by those who cared about smoking risks, but did not consider quitting as a priority. Conclusions Characteristics of smoking initiation in youth may have far-reaching associations with how smoking risks are assessed by adults of reproductive age, and their intentions to quit smoking. Becoming a regular smoker at under the age of 16 years, and influences of alcohol on smoking uptake, were inversely associated with high-level assessment of smoking risks and intention to quit in regional Aboriginal smokers

    Full Text Available The purpose of this study was to estimate black/white differences in cotinine levels for current smokers of both sexes, and to explore the potential contribution of mentholated cigarettes to these differences. Sera from 255 current smokers sampled from Southern Community Cohort Study participants (65 black men, 65 black women, 63 white men, 62 white women were analyzed for cotinine, and linear regression was used to model the effect of race on cotinine level, adjusting for the number of cigarettes smoked within the last 24 hours, use of menthol vs. non-menthol cigarettes, exposure to environmental tobacco smoke, and age. Black smokers smoked fewer cigarettes than white smokers, yet had crude mean cotinine levels nearly as high or higher than white smokers. After multivariate adjustment, cotinine levels were an average of 50 ng/ml higher among black than white women (p=0.008 and non-significantly 12 ng/ml higher among black than white men (p=0.52. We observed no increase in cotinine levels associated with menthol cigarette use. We conclude that differences in cotinine levels among smokers suggest racial variation in exposure to and/or metabolism of tobacco smoke constituents, but our findings do not support a role for menthol preference in this disparity.

  3. Economics and cigarettes.

    Schelling, T C

    1986-09-01

    Economic facts on cigarette consumption and production are summarized, and the health consequences of cigarette smoking are reviewed. The magnitude and distribution of these health consequences among the population are discussed in economic terms, that is, in an "accounting framework" comprising such disparate elements as lost lives, lost livelihoods, pain, fear, discomfort, medical costs, excise taxes, and the costs of regulating smoking behaviors. The importance of these factors and their potential influence on public policy and individual behavior are considered. Difficulties include assigning a monetary value to an expected extension of life, the "voluntary" nature of smoking (even though most smokers wish they could quit), deciding what to include as economic consequences of smoking, and the attribution to smoking of some share of the costs for diseases known to be affected by smoking. "Transfers," or purely financial transactions, in contrast to expenditures for goods and services, are explained as one assessment component of the economic impact of smoking-related diseases. The issue of the economic benefit to the United States as a whole and to the population engaged in the cigarette industry, because of the earnings and employment generated by cigarette purchases, is examined, as is the issue of cigarette purchases as a significant source of federal and state revenue.

    Polonium (210Po), the most volatile of naturally-occurring radionuclides in plants, was analysed in three common brands of cigarettes produced in Portugal. The analyses were carried out on the unburned tobacco contained in cigarettes, on the ashes and butts of smoked cigarettes and on the mainstream smoke. 210Po in tobacco displays concentrations ranging from 3 to 37 mBq g-1, depending upon the cigarette brand. The 210Po activity remaining in the solid residue of a smoked cigarette varied from 0.3 to 4.9 mBq per cigarette, and the 210Po in the inhaled smoke varied from 2.6 to 28.9 mBq. In all brands of cigarettes tested, a large fraction of the 210Po content is not inhaled by the smoker and it is released into the atmosphere. Part of it may be inhaled by passive smokers. Depending upon the commercial brand and upon the presence or absence of a filter in the cigarette, 5 to 37 % of the 210Po in the cigarette can be inhaled by the smoker. Taking into account the average 210Po in surface air, the smoker of one pack of twenty cigarettes per day may inhale 50 times 210Po than a non smoker. Cigarette smoke contributes with 1.5 % to the daily rate of 210Po absorption into the blood, 0.39 Bq d-1, and, after systemic circulation it gives rise to a whole body radiation dose in the same proportion. However, in the smoker the deposition of 210Po in the lungs is much more elevated than normal and may originate an enhanced radiation exposure. Estimated dose to the lungs is presented and radiobiological effects of cigarette smoke are discussed.

    Despite increasing popularity, health consequences of vaping (smoking electronic cigarettes, e-cigarettes) are poorly described. Few studies suggest that vaping has less deleterious effects on lung function than smoking conventional cigarettes. One large study found that e-cigarettes were as efficient as nicotine patches in smoking cessation. The long-term consequences of vaping are however unknown and while some experts are open towards e-cigarettes as a safer way of satisfying nicotine addiction, others worry that vaping in addition to presenting a health hazard may lead to an increased number of smokers of conventional cigarettes.

    BACKGROUND Cigarette smoke has been identified as the main cause of oral cavity carcinoma. Recently, the electronic cigarette, a battery-operated device, was developed to help smokers stop their tobacco addiction. This study aimed to evaluate the safety of electronic cigarettes and to establish the possible role of such device in the primary prevention of oral cavity cancer. SUBJECTS AND METHODS This study included 65 subjects who were divided into three groups (smokers, e-cigarette smokers, and nonsmokers). All subjects were submitted to cytologic examination by scraping of oral mucosa. The slides were microscopically evaluated through a micronucleus assay test. RESULTS The prevalence of micronuclei was significantly decreased in the e-cigarette smoker group. There were no statistically significant differences in micronuclei distribution according to the type of cigarette, gender, and age. CONCLUSIONS The use of electronic cigarettes seems to be safe for oral cells and should be suggested as an aid to smoking cessation.

    This research examines the salient attitudes and beliefs that college students hold about cigarette smoking. An exploratory survey was employed that contained a combination of semantic differential items and open-ended questions. The data indicated that smoking status (i.e., whether a student is a nonsmoker, smoker, or ex-smoker) was related to attitudes about the attractiveness, riskiness, and intelligence of cigarette smoking. Additionally, salient beliefs about smoking include that nonsmokers report never smoking due to health reasons, smokers and ex-smokers both report peer pressure as the primary reason for starting to smoke, and the main reason smokers continue to smoke is because they are addicted. The best thing reported about smoking was that it relieves stress, and the worst thing reported about smoking was the smell. Several suggestions are made for future interventions targeted toward college students. PMID:15255159

    The objective of this study was to assess the cigarette purchase patterns of smokers in Erie and Niagara Counties following recent increases in the state excise tax for cigarettes. Data were collected with telephone interviews of a sample of 1,548 randomly selected people in Erie and Niagara Counties between October 2002 and March 2003. Purchase patterns were assessed for the 908 smokers in the sample who responded to questions about cigarette purchasing patterns. Thirty-three percent reported that their usual source of cigarettes is from a small store, large store, pharmacy, or vending machine, while 67% reported that their usual source is from an Indian reservation. Only one smoker reported the Internet was a usual source of cigarettes. The average price paid per pack was $4.80 in a small store and $1.91 on an Indian reservation. Price influences smoking behavior; however, the majority of smokers are taking advantage of readily available venues where less expensive, untaxed cigarettes are sold. This may undermine the public health benefit of higher prices and cause lost revenue to state and local governments. PMID:15643371

    Full Text Available Pulmonary Langerhans Cell Histiocytosis (PLCH is a rare idiopathic disorder that primarily affects young adult cigarette smokers. Affected patients often present with cough and dyspnea and about 20% of patients present with or later develop pneumothorax. It is striking that more than 90% of patients are smokers. We report a very unusual case of PLCH in a 20-year- old male patient with no smoking history in whom a life- threatening complication such as simultaneous bilateral pneumothorax was the presenting feature. The final diagnosis was made by open surgical biopsy and recurrent pneumothoraces necessitated surgical management with pleurodesis. We emphasize the early use of pleurodesis in managing patients with PLCH and spontaneous pneumothorax.

    Full Text Available Age and metabolic syndrome are major risk factors for atherosclerosis. However, limited information is available regarding whether cigarette smoking, another major, modifiable risk factor, has synergistic effects with age and metabolic syndrome on subclinical atherosclerosis, particularly in young adults. This aspect was examined in 1,051 adults (747 whites and 304 blacks; aged 24-43 years from the Bogalusa Heart Study. General linear models were used to examine the effects of cigarette smoking and its interactive effects with age and metabolic syndrome on carotid intima-media thickness (CIMT. After adjusting for age, race, and sex, current smokers had lower BMI (mean ± SE: 27.4 ± 0.4, 29.3 ± 0.5, and 29.9 ± 0.3 kg/m2 in current, former, and never smokers, respectively; p<0.0001 and lower levels of fasting glucose (82.8 ± 0.9, 89.5 ± 2.3, and 87.1 ± 1.1 mg/dL, respectively; p = 0.001 and insulin (10.6 ± 0.4, 14.2 ± 1.0, 13.6 ± 0. 6 µU/ml, respectively; p<0.0001. Despite being lean and having favorable levels of glucose and insulin, current smokers had greater CIMT (0.850 ± 0.012, 0.808 ± 0.011, and 0.801 ± 0.006 mm, respectively; p = 0.0004. Importantly, cigarette smoking showed significant interactions with age and metabolic syndrome on CIMT: Age-related change in CIMT in current smokers was significantly greater (0.013 ± 0.002 mm/year than in nonsmokers (former and never smokers combined (0.008 ± 0.001 mm/year (p for interaction = 0.005; the difference in CIMT between those with and without metabolic syndrome was significantly greater in current smokers (0.154 ± 0.030 mm, p<0.0001 than in nonsmokers (0.031 ± 0.014 mm, p = 0.03 (p for interaction<0.0001. In conclusion, cigarette smoking significantly exacerbates the adverse effects of age and metabolic syndrome on subclinical atherosclerosis in young adults, which underscores the importance of prevention and cessation of cigarette smoking behavior in the young.

    Full Text Available We examine differences between college students and non-students with respect to orientation toward e-cigarettes. Participants were U.S. adults 18-24 (465 students, 409 non-students. Data collection employed an online survey by GfK Custom Research. Smoking, vaping, and use of alternate tobacco were assessed, as were variables from the Theory of Reasoned Action and Diffusion of Innovations. This study showed that smoking status largely explains use and orientation toward electronic cigarettes among both students and non-students, with differences attributable to higher smoking rates among non-students. Results also showed that among student smokers there was a greater level of information exposure concerning electronic cigarettes, and more prevalence in the use of alternate tobacco. Hookah use in that group was significantly greater than for non-student smokers. Together these findings suggest that students may be more vulnerable to electronic cigarette use due to higher related information exposure and the integration of vaping into hookah culture.

    Prenatal cigarette smoke exposure (PCSE) has been associated with physiological and developmental changes that may be related to an increased risk for childhood and adult neuropsychiatric diseases. The present study investigated locomotor activity and cholinesterase enzyme activity in rats, following PCSE and/or ketamine treatment in adulthood. Pregnant female Wistar rats were exposed to 12 commercially filtered cigarettes per day for a period of 28 days. We evaluated motor activity and cholinesterase activity in the brain and serum of adult male offspring that were administered acute subanesthetic doses of ketamine (5, 15 and 25 mg/kg), which serves as an animal model of schizophrenia. To determine locomotor activity, we used the open field test. Cholinesterase activity was assessed by hydrolysis monitored spectrophotometrically. Our results show that both PCSE and ketamine treatment in the adult offspring induced increase of locomotor activity. Additionally, it was observed increase of acetylcholinesterase and butyrylcholinesterase activity in the brain and serum, respectively. We demonstrated that animals exposed to cigarettes in the prenatal period had increased the risk for psychotic symptoms in adulthood. This also occurs in a dose-dependent manner. These changes provoke molecular events that are not completely understood and may result in abnormal behavioral responses found in neuropsychiatric disorders, such as schizophrenia.

    Full Text Available Abstract Background This study uses cigarette price elasticity to evaluate the effect of a new excise tax increase on cigarette consumption and to investigate responses from various types of smokers. Methods Our sample consisted of current smokers between 17 and 69 years old interviewed during an annual face-to-face survey conducted by Taiwan National Health Research Institutes between 2000 to 2003. We used Ordinary Least Squares (OLS procedure to estimate double logarithmic function of cigarette demand and cigarette price elasticity. Results In 2002, after Taiwan had enacted the new tax scheme, cigarette price elasticity in Taiwan was found to be -0.5274. The new tax scheme brought about an average annual 13.27 packs/person (10.5% reduction in cigarette consumption. Using the cigarette price elasticity estimate from -0.309 in 2003, we calculated that if the Health and Welfare Tax were increased by another NT$ 3 per pack and cigarette producers shifted this increase to the consumers, cigarette consumption would be reduced by 2.47 packs/person (2.2%. The value of the estimated cigarette price elasticity is smaller than one, meaning that the tax will not only reduce cigarette consumption but it will also generate additional tax revenues. Male smokers who had no income or who smoked light cigarettes were found to be more responsive to changes in cigarette price. Conclusions An additional tax added to the cost of cigarettes would bring about a reduction in cigarette consumption and increased tax revenues. It would also help reduce incidents smoking-related illnesses. The additional tax revenues generated by the tax increase could be used to offset the current financial deficiency of Taiwan's National Health Insurance program and provide better public services.

    In non-smokers, passive heat stress increases shear stress and vasodilation, decreasing arterial stiffness. Smokers, who reportedly have arterial dysfunction, may have similar improvements in arterial stiffness with passive heat stress. Therefore, we examined the effects of an acute bout of whole-body passive heat stress on arterial stiffness in smokers vs. non-smokers. Thirteen smokers (8.8 ± 5.5 [median = 6] cigarettes per day for >4 years) and 13 non-smokers matched for age, mass, height, and exercise habits (27 ± 8 years; 78.8 ± 15.4 kg; 177.6 ± 6.7 cm) were passively heated to 1.5 °C core temperature ( T C) increase. At baseline and each 0.5 °C T C increase, peripheral (pPWV) and central pulse wave velocity (cPWV) were measured via Doppler ultrasound. No differences existed between smokers and non-smokers for any variables (all p > 0.05), except cPWV slightly increased from baseline (526.7 ± 81.7 cm · s-1) to 1.5 °C Δ T C (579.7 ± 69.8 cm · s-1; p 0.05). Changes in cPWV and pPWV during heating correlated ( p smoking status, baseline stiffness appears to mediate the magnitude of heating-induced changes in arterial stiffness.

    2014-01-01

    The research field on e-cigarettes is characterized by severe methodological problems, severe conflicts of interest, relatively few and often small studies, inconsistencies and contradictions in results, and a lack of long-term follow-up. Therefore, no firm conclusions can be drawn on the harm of e-cigarettes......, but they can hardly be called safe. Experimental studies indicate negative health effects and, amongst others, the major ingredient propylene glycol warrants concern. Growing evidence raises doubt about the efficacy of e-cigarettes as a smoking cessation aid. Unfortunately, it seems that many smokers use e-cigarettes...... with the intention to quit but switch to long-term use of e-cigarettes or dual use. Use is spreading rapidly to minors, ex-smokers, and never-smokers. It is questionable whether the potential health benefits obtained by some smokers outweigh the potential harm by use of non-smokers, of undermining of complete...

    Recently, genome-wide association studies have identified and validated genetic variations associated with urinary bladder cancer (UBC). However, it is still unknown whether the high-risk alleles of several SNPs interact with one another, leading to an even higher disease risk. Additionally, there is no information available on how the UBC risk due to these SNPs compare to the risk of cigarette smoking and to occupational exposure to urinary bladder carcinogens, and whether the same or different SNP combinations are relevant in smokers and non-smokers. To address these questions, we analyzed the genotypes of six SNPs, previously found to be associated with UBC, together with the GSTM1 deletion, in 1,595 UBC cases and 1,760 controls, stratified for smoking habits. We identified the strongest interactions of different orders and tested the stability of their effect by bootstrapping. We found that different SNP combinations were relevant in smokers and non-smokers. In smokers, polymorphisms involved in detoxification of cigarette smoke carcinogens were most relevant (GSTM1, rs11892031), in contrast to those in non-smokers with MYC and APOBEC3A near polymorphisms (rs9642880, rs1014971) being the most influential. Stable combinations of up to three high-risk alleles resulted in higher odds ratios (OR) than the individual SNPs, although the interaction effect was less than additive. The highest stable combination effects resulted in an OR of about 2.0, which is still lower than the ORs of cigarette smoking (here, current smokers' OR: 3.28) and comparable to occupational carcinogen exposure risks which, depending on the workplace, show mostly ORs up to 2.0.

    It is widely accepted that tabagism is a predisposing factor to oral candidosis and cumulate data suggest that cigarette compounds may increase candidal virulence. To verify if enhanced virulence occurs in Candida albicans from chronic smokers, a cohort of 42 non-smokers and other of 58 smokers (all with excellent oral conditions and without signs of candidosis) were swabbed on tong dorsum and jugal mucosa. Results showed that oral candidal loads do not differ between smoker and non-smokers. Activities of secreted aspartyl-protease (Sap), phospholipase, chondroitinase, esterase-lipase, and haemolysin secretions were screened for thirty-two C. albicans isolates. There were detected significant increments in phospholipasic and chondroitinasic activities in isolates from non-smokers. For other virulence factors, no differences between both cohorts were achieved. PMID:21924704

    Full Text Available Abstract Background Characterizing and comparing the determinant of cotinine concentrations in different populations should facilitate a better understanding of smoking patterns and addiction. This study describes and characterizes determinants of salivary cotinine concentration in a sample of Spanish adult daily smoker men and women. Methods A cross-sectional study was carried out between March 2004 and December 2005 in a representative sample of 1245 people from the general population of Barcelona, Spain. A standard questionnaire was used to gather information on active tobacco smoking and passive exposure, and a saliva specimen was obtained to determine salivary cotinine concentration. Two hundred and eleven adult smokers (>16 years old with complete data were included in the analysis. Determinants of cotinine concentrations were assessed using linear regression models. Results Salivary cotinine concentration was associated with the reported number of cigarettes smoked in the previous 24 hours (R2 = 0.339; p R2 = 0.386; p Conclusion This study shows that salivary cotinine concentration is significantly associated with the number of cigarettes smoked and sex, but not with other smoking-related variables.

    2016-01-01

    Background: Traditional cigarette advertising has existed in the US for over 200 years. Studies suggest that advertising has an impact on the initiation and maintenance of smoking behaviors. In recent years, electronic cigarettes (e-cigarettes) emerged on the market as an alternative to the traditional tobacco cigarette. The purpose of this study was to describe advertisements in popular US magazines marketed to women for cigarettes and e-cigarettes. Methods: This study involved analyzing 99 issues of 14 popular US magazines marketed to women. Results: Compared to advertisements for traditional cigarettes, advertisements for e-cigarettes were more often found in magazines geared toward the 31–40-year-old audience (76.5% vs. 53.1%, P = 0.011) whereas traditional cigarette advertisements were nearly equally distributed among women 31–40 and ≥40 years. More than three-quarters of the e-cigarette advertisements presented in magazines aimed at the higher median income households compared to a balanced distribution by income for traditional cigarettes (P = 0.033). Conclusions: Future studies should focus on specific marketing tactics used to promote e-cigarette use as this product increases in popularity, especially among young women smokers. PMID:27688867

    Little is known about the consistency of people's reasons for smoking and how these might influence the amount of smoking in individuals. Therefore, we developed a new concept, motivational flexibility, which suggests that a behavior is more common when people have multiple reasons for engaging in it and when the primary reason changes across occurrences of the behavior. The purpose of this study was to examine motivational flexibility in cigarette smokers. We hypothesized that smoking would be associated with greater number of reasons for smoking and greater frequency of change (shifting) in the most important motive for smoking among light smokers. Student cigarette smokers (N=116) completed daily entries for 14 days: whether they smoked or not and their reasons for doing so, with importance ratings for each reason listed. Multilevel modeling was used to examine the relationship between motivational flexibility and daily cigarette smoking. Shifting among the most important motive over the 14-day assessment was associated with greater frequency of smoking in light but not daily smokers. Also, smoking for craving and social reasons was associated with smoking fewer cigarettes and on fewer days. Results confirm the applicability of the motivational flexibility concept to smoking. The association between motive shifting and greater frequency of smoking may indicate a greater responsiveness to environmental cues. That we found this association in light but not daily smokers who are likely addicted to cigarettes may indicate that light smokers are affected more by triggers for smoking, or that they may rationalize their smoking behavior more than heavier smokers.

    Mutations in the essential telomerase genes TERT and TR cause familial pulmonary fibrosis; however, in telomerase-null mice, short telomeres predispose to emphysema after chronic cigarette smoke exposure. Here, we tested whether telomerase mutations are a risk factor for human emphysema by examining their frequency in smokers with chronic obstructive pulmonary disease (COPD). Across two independent cohorts, we found 3 of 292 severe COPD cases carried deleterious mutations in TERT (1%). This p...

  9. [Cigarette prices, tobacco taxes and the proportion of contraband cigarettes in Germany].

    Taxes on tobacco products are among the most efficient instruments against tobacco consumption and the arising cost of illness associated with them. The main argument of the tobacco industry against increases of excise taxes on cigarettes is a presumed substitution effect of smokers turning from consumption of legal cigarettes to smuggled ones. Besides deriving this proposition from the tobacco industry's own funded research, it has never been tested empirically. This article analyses the interdependence between contraband cigarettes and cigarette prices in Germany. Using VAR-modelling on the time-series of the variables of interest, we find no empirically valid correlation or causation between prices and untaxed contraband cigarettes. Furthermore, we find a positive relationship between contraband and legal taxed cigarettes, i. e., when the demand for legal cigarettes decreased in amount, so did the quantity of untaxed cigarettes. We conclude that the proposed relationship between prices and smuggled cigarettes as well as an overall substitution effect among smokers is non-existent. This has important implications for public health policy. The proposition that higher taxes on tobacco products incur social costs from increased smuggling activity cannot be corroborated empirically. Furthermore, this finding should encourage public health policy to keep using tobacco taxes as an instrument for prevention. PMID:22932830

    This study investigated the relationship between plasma and saliva cotinine kinetics after smoking one cigarette and the relationship between cotinine kinetics and estimated nicotine intake, which was calculated as mouth level exposure (MLE) of nicotine, from smoking two test cigarettes with different nicotine yields. This study was conducted in 16 healthy adult Japanese smokers, who did not have null nor reduced-activity alleles of CYP2A6, with a quasi-randomized crossover design of smoking a low-tar cigarette or a high-tar cigarette. Saliva cotinine showed similar concentration profiles to plasma cotinine, and all of the calculated pharmacokinetic parameters of cotinine showed the same values in plasma and saliva. The Cmax and AUC of cotinine showed almost the same dose-responsiveness to the estimated MLE of nicotine between plasma and saliva, but the tmax and t1/2 of cotinine were not affected by the estimated MLE of nicotine in either plasma or saliva. The results show that saliva cotinine kinetics reflects plasma cotinine kinetics, and measurement of saliva cotinine concentration gives the same information as plasma cotinine on the nicotine intake. Thus, saliva cotinine would be a good and less-invasive exposure marker of cigarette smoke, reflecting the plasma cotinine concentration and kinetics.

    Full Text Available Abstract Background The prevalence of waterpipe tobacco smoking (WTS in the Middle East region and worldwide is increasing. There is evidence to indicate both short term and long term health effects of WTS, resulting in the issuance of an advisory note by the World Health Organization. Methods This research aimed at gaining an in-depth understanding of the factors contributing to the rise in WTS in Lebanon. Qualitative focus groups (25 and in-depth interviews (9 were conducted with adults in Lebanon in 2007. Participants were recruited to represent diversity in smoking status, gender, age groups and urban/rural residence. The interviews and focus groups were thematically analyzed, and recurrent themes noted and summarized. Results The main themes identified were availability, affordability, innovation, influence of media, lack of a policy framework, and the sensory characteristics evoked from WTS. Men and women, smokers and non-smokers, and younger and older participants differed in their emphases on the above themes. These themes, though specific to waterpipe, are similar to themes manipulated by the cigarette industry, and eventually controlled through tobacco control policies. Conclusions Understanding reasons behind the rise in waterpipe tobacco use is important if appropriate prevention, cessation, and policy interventions are to be formulated. Strict adherence to the FCTC is warranted, with careful and vigilant attention that all tobacco products are covered by laws in both high as well as middle to lower income countries.

    Full Text Available ABSTRACT Introduction: Although the harmful effects of smoking on the cardiovascular and respiratory systems have been established for a long time, the effect on physiological and physical parameters in modern female dancers is not well documented. Objective: To determine differences in selected pulmonary functions, biochemical parameters, and body composition in female smoker and non-smoker modern dancers who are university or graduate students. Methods: A total of twenty-two female modern dancers (mean age of 24.6 ± 4.3 years, who were non-smokers (n = 11 and smokers (n = 11, voluntarily participated in the study. The smokers had been smoking 1 to 20 cigarettes per day for an average period of seven years. The pulmonary function test Mir Spirobank Spirometer, (Italy was applied; selected biochemical parameters were tested, and various anthropometric measurements (height, weight and seven skinfold thickness were performed. The results of body composition were evaluated using Jackson-Pollock equations. Intergroup comparisons were performed using the Mann-Whitney U test. Result: No significant differences were found between smoker and non-smoker dancers in terms of body composition (body fat, % body fat, lean body fat and selected biochemical parameters (p > 0.05. However, non-smokers had prediction values of forced expiratory volume during the first second (FEV1 and peak expiratory flow (PEF significantly better (p < 0.05. The effect of smoking on the performance of female modern dancers should be examined in a longitudinal study, with a higher number of participants. Conclusion: It was observed that smoking reduces lung pulmonary capacity at a certain rate, although the biochemical parameters and body composition of the female smoker and non-smoker dancers were similar.

    Exposure to cigarette smoke is known to result in impaired host defense responses and immune suppressive effects. However, the effects of new and emerging tobacco products, such as e-cigarettes, on the immune status of the respiratory epithelium are largely unknown. We conducted a clinical study collecting superficial nasal scrape biopsies, nasal lavage, urine, and serum from nonsmokers, cigarette smokers, and e-cigarette users and assessed them for changes in immune gene expression profiles. Smoking status was determined based on a smoking history and a 3- to 4-wk smoking diary and confirmed using serum cotinine and urine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) levels. Total RNA from nasal scrape biopsies was analyzed using the nCounter Human Immunology v2 Expression panel. Smoking cigarettes or vaping e-cigarettes resulted in decreased expression of immune-related genes. All genes with decreased expression in cigarette smokers (n = 53) were also decreased in e-cigarette smokers. Additionally, vaping e-cigarettes was associated with suppression of a large number of unique genes (n = 305). Furthermore, the e-cigarette users showed a greater suppression of genes common with those changed in cigarette smokers. This was particularly apparent for suppressed expression of transcription factors, such as EGR1, which was functionally associated with decreased expression of 5 target genes in cigarette smokers and 18 target genes in e-cigarette users. Taken together, these data indicate that vaping e-cigarettes is associated with decreased expression of a large number of immune-related genes, which are consistent with immune suppression at the level of the nasal mucosa.

    Teenage cigarette smoking is sensitive to the price of cigarettes. The most recent research suggests that a 10% increase in price would reduce the number of teenagers who smoke by 7%. If the proposed 43-cent hike in the Federal excise tax rate on cigarettes contained in the Hatch-Kennedy Bill were enacted, the number of teenage smokers would fall by approximately 16%.

  18. Do electronic cigarettes help with smoking cessation?

    Science.gov (United States)

    2014-11-01

    Smoking causes around 100,000 deaths each year in the UK, and is the leading cause of preventable disease and early mortality. Smoking cessation remains difficult and existing licensed treatments have limited success. Nicotine addiction is thought to be one of the primary reasons that smokers find it so hard to give up, and earlier this year DTB reviewed the effects of nicotine on health. Electronic cigarettes (e-cigarettes) are nicotine delivery devices that aim to mimic the process of smoking but avoid exposing the user to some of the harmful components of traditional cigarettes. However, the increase in the use of e-cigarettes and their potential use as an aid to smoking cessation has been subject to much debate. In this article we consider the regulatory and safety issues associated with the use of e-cigarettes, and their efficacy in smoking cessation and reduction.

Reasons cited by the regulatory bodies for its ouster were the toxic contents it contained. Some countries preferred to ban them while some have legalised them. However, the manufacturers have claimed that it does have the potential to help smokers quit or at least replace the conventional cigarettes which cause millions of death globally. Research is hence needed to prove the efficacy and utility of this device for welfare of people who are looking for better options than puffing cigarettes. (author)

    Full Text Available OBJECTIVE: The use of pictorial warning labels on cigarette packages is one of the provisions included in the first ever global health treaty by the World Health Organization against the tobacco epidemic. There is substantial evidence demonstrating the effectiveness of graphic health warning labels on intention to quit, thoughts about health risks and engaging in cessation behaviors. However, studies that address the implicit emotional drives evoked by such warnings are still underexplored. Here, we provide experimental data for the use of pictorial health warnings as a reliable strategy for tobacco control. METHODS: Experiment 1 pre-tested nineteen prototypes of pictorial warnings to screen for their emotional impact. Participants (n = 338 were young adults balanced in gender, smoking status and education. Experiment 2 (n = 63 tested pictorial warnings (ten that were stamped on packs. We employed an innovative set-up to investigate the impact of the warnings on the ordinary attitude of packs' manipulation, and quantified judgments of warnings' emotional strength and efficacy against smoking. FINDINGS: Experiment 1 revealed that women judged the warning prototypes as more aversive than men, and smokers judged them more aversive than non-smokers. Participants with lower education judged the prototypes more aversive than participants with higher education. Experiment 2 showed that stamped warnings antagonized the appeal of the brands by imposing a cost to manipulate the cigarette packs, especially for smokers. Additionally, participants' judgments revealed that the more aversive a warning, the more it is perceived as effective against smoking. CONCLUSIONS: Health warning labels are one of the key components of the integrated approach to control the global tobacco epidemic. The evidence presented in this study adds to the understanding of how implicit responses to pictorial warnings may contribute to behavioral change.

    Full Text Available Objective. Among current smokers, the proportion of Nondaily smokers is increasing. A better understanding of the characteristics and smoking behaviors of Nondaily smokers is needed. Methods. We analyzed data from the New York City (NYC Community Health Survey to explore Nondaily smoking among NYC adults. Univariate analyses assessed changes in Nondaily smoking over time (2002–2010 and identified unique characteristics of Nondaily smokers; multivariable logistic regression analysis identified correlates of Nondaily smoking in 2010. Results. The proportion of smokers who engage in Nondaily smoking significantly increased between 2002 and 2010, from 31% to 36% (P=0.05. A larger proportion of Nondaily smokers in 2010 were low income and made tax-avoidant cigarette purchases compared to 2002. Smoking behaviors significantly associated with Nondaily smoking in 2010 included smoking more than one hour after waking (AOR=8.8, 95% CI (5.38–14.27; buying “loosies” (AOR=3.5, 95% CI (1.72–7.08; attempting to quit (AOR=2.3, 95% CI (1.36–3.96. Conclusion. Nondaily smokers have changed over time and have characteristics distinct from daily smokers. Tobacco control efforts should be targeted towards “ready to quit” Nondaily smokers.

    Emotion regulation dysfunctions are assumed to contribute to the development of tobacco addiction and relapses among smokers attempting to quit. To further examine this hypothesis, the present study compared heavy smokers with non-smokers (NS) in a reappraisal task. Specifically, we investigated whether non-deprived smokers (NDS) and deprived smokers (DS) differ from non-smokers in cognitive emotion regulation and whether there is an association between the outcome of emotion regulation and the cigarette craving. Sixty-five participants (23 non-smokers, 22 NDS, and 20 DS) were instructed to down-regulate emotions by reappraising negative or positive pictorial scenarios. Self-ratings of valence, arousal, and cigarette craving as well as facial electromyography and electroencephalograph activities were measured. Ratings, facial electromyography, and electroencephalograph data indicated that both NDS and DS performed comparably to nonsmokers in regulating emotional responses via reappraisal, irrespective of the valence of pictorial stimuli. Interestingly, changes in cigarette craving were positively associated with regulation of emotional arousal irrespective of emotional valence. These results suggest that heavy smokers are capable to regulate emotion via deliberate reappraisal and smokers’ cigarette craving is associated with emotional arousal rather than emotional valence. This study provides preliminary support for the therapeutic use of reappraisal to replace maladaptive emotion-regulation strategies in nicotine addicts. PMID:26528213

    Science.gov (United States)

    2012-03-30

    Increasing the price of cigarettes reduces the demand for cigarettes, thereby reducing youth smoking initiation and cigarette consumption and decreasing the prevalence of cigarette use in the United States overall, particularly among youths and young adults. The most common way governments have increased the price of cigarettes is by increasing cigarette excise taxes, which currently are imposed by all states and the District of Columbia. To update data on state cigarette excise taxes in 2009, CDC conducted a survey of changes in state cigarette excise taxes during 2010-2011. During that period, eight states increased their cigarette excise taxes, and one state decreased its tax; as a result, the mean state tax increased from $1.34 in 2009 to $1.46 in 2011. Previous evidence indicates that further increases in cigarette excise taxes would be expected to result in further reductions in demand for cigarettes, decreasing smoking and associated morbidity and mortality.

    Background: There is scarce evidence about passive exposure to the vapour released or exhaled from electronic cigarettes (e-cigarettes) under real conditions. The aim of this study is to characterise passive exposure to nicotine from e-cigarettes' vapour and conventional cigarettes' smoke at home among non-smokers under real-use conditions. Methods: We conducted an observational study with 54 non-smoker volunteers from different homes: 25 living at home with conventional smokers, 5 living with nicotine e-cigarette users, and 24 from control homes (not using conventional cigarettes neither e-cigarettes). We measured airborne nicotine at home and biomarkers (cotinine in saliva and urine). We calculated geometric mean (GM) and geometric standard deviations (GSD). We also performed ANOVA and Student's t tests for the log-transformed data. We used Bonferroni-corrected t-tests to control the family error rate for multiple comparisons at 5%. Results: The GMs of airborne nicotine were 0.74 μg/m{sup 3} (GSD=4.05) in the smokers’ homes, 0.13 μg/m{sup 3} (GSD=2.4) in the e-cigarettes users’ homes, and 0.02 μg/m{sup 3} (GSD=3.51) in the control homes. The GMs of salivary cotinine were 0.38 ng/ml (GSD=2.34) in the smokers’ homes, 0.19 ng/ml (GSD=2.17) in the e-cigarettes users’ homes, and 0.07 ng/ml (GSD=1.79) in the control homes. Salivary cotinine concentrations of the non-smokers exposed to e-cigarette's vapour at home (all exposed ≥2 h/day) were statistically significant different that those found in non-smokers exposed to second-hand smoke ≥2 h/day and in non-smokers from control homes. Conclusions: The airborne markers were statistically higher in conventional cigarette homes than in e-cigarettes homes (5.7 times higher). However, concentrations of both biomarkers among non-smokers exposed to conventional cigarettes and e-cigarettes’ vapour were statistically similar (only 2 and 1.4 times higher, respectively).

    Full Text Available Cigarette butts are consistently the most collected items in litter clean-up efforts, which are a costly burden to local economies. In addition, tobacco waste may be detrimental to our natural environment. The tobacco industry has conducted or funded numerous studies on smokers’ littering knowledge and behavior, however, non-industry sponsored research is rare. We sought to examine whether demographics and smokers’ knowledge and beliefs toward cigarette waste as litter predicts littering behavior. Smokers aged 18 and older (n = 1,000 were interviewed about their knowledge and beliefs towards cigarette waste as litter. Respondents were members of the Research Now panel, an online panel of over three million respondents in the United States. Multivariate logistic regressions were conducted to determine factors significantly predictive of ever having littered cigarette butts or having littered cigarette butts within the past month (p-value < 0.05. The majority (74.1% of smokers reported having littered cigarette butts at least once in their life, by disposing of them on the ground or throwing them out of a car window. Over half (55.7% reported disposing of cigarette butts on the ground, in a sewer/gutter, or down a drain in the past month. Those who did not consider cigarette butts to be litter were over three and half times as likely to report having ever littered cigarette butts (OR = 3.68, 95%CI = 2.04, 6.66 and four times as likely to have littered cigarette butts in the past month (OR = 4.00, 95%CI = 2.53, 6.32. Males were significantly more likely to have littered cigarette butts in the past month compared to females (OR = 1.49, 95%CI = 1.14, 1.94. Holding the belief that cigarette butts are not litter was the only belief in this study that predicted ever or past-month littering of cigarette waste. Messages in anti-cigarette-litter campaigns should emphasize that cigarette butts are not just litter but are toxic

    This study describes the prevalence of reported history of traumatic brain injury (TBI) and its association with reports of current substance use, cigarette smoking, and psychological distress among Canadian adults in a population sample. A cross-sectional sample of 1999 Ontario adults 18-93 years of age were surveyed by telephone in 2011 as part of the Center for Addiction and Mental Health's ongoing representative survey of adult mental health and substance use in Ontario, Canada. Loss of consciousness for at least 5 min or at least one overnight hospitalization resulting from symptoms associated with the TBI injury represented minimum criteria for TBI. An estimated 16.8% (95% confidence interval, 14.8, 19.0) of adults reported a TBI in their lifetime. Men had higher prevalence of TBI than women. Adults who reported a history of TBI had higher odds of reported past-year daily smoking (adjusted odds ratio [AOR] = 2.15), using cannabis (AOR = 2.80) and nonmedical opioids (AOR = 2.90), as well as screened significantly for recent elevated psychological distress (AOR = 1.97) in the past few weeks, compared to adults without a history of TBI. Co-occurrence of a history of TBI with current elevated psychological distress and substance use warrants vigilance among medical practitioners to assess the possibility of a history of TBI during reviews of the history leading to the occurrence of these conditions.

    Full Text Available Asthma environmental triggers play important roles in severity of disease. Passive smoking could exacerbate asthma symptoms and enhance the decrease in lung function. Cotinine levels could be a reflection of passive exposure to the cigarette both in adults and pediatrics. The aim of this study was to determine degree of association of asthma severity and cotinine level as a marker of passive smoking. In a cross-sectional study, 100 pediatric patients (under 10 years old with asthma were enrolled, 50 of whom, had been exposed to passive smoking and 50 others included as controls. A complete clinical history, lab exam, and spirometry were performed. A sample of urine, serum and saliva was collected from all attendant patients and controls in the study after confirmation of diagnosis and determination of severity of asthma. The results revealed that age, sex, age of onset of asthma, family history and allergic history were not significantly different between two groups of patients. According to GINA classification, percentage of patients with severe asthma was significantly higher in passive smoker group (p=0.001. Cotinine was significantly higher in passive smoker group compared to control group in serum (p=001, saliva (p=0.001, and urine (p=0.0014. In passive smoker group, cotinine levels were significantly higher in serum (p=0.001, urine (p=0.007, and saliva (p=0.01 of patients with severe asthma than moderate and mild asthma. Serum cotinine (OR: 1.81, 95% CI: 1.35-2.32, p=0.024, urine cotinine (OR: 3.56,95% CI = 1.29-5.53, p=0.01 and saliva cotinine (OR: 1.66, 95% CI: 1.23-1.98, p=0.031 were also significantly associated with higher risk of severe asthma. Cotinine levels were higher in passive smokers compared to non-passive smokers. Besides, cotinine was a predictive risk factor for severe asthma.

    Cigarette smoke, which contains many harmful compounds, affects not only the smoker's health but also indoor air quality. To evaluate indoor air contamination by cadmium (Cd) and lead (Pb), we measured Cd and Pb contained in the mainstream and sidestream smoke exhaled by experimental smoking of Japanese cigarettes and also determined urinary and blood Cd and Pb levels in smokers and non-smokers and air Cd and Pb levels in smoky environments. 1. One cigarette of each of 7 Japanese brands contained about 1 microgram each of Cd and Pb, of which about 50 ng each was released to the mainstream and 250 ng of Cd and 50 ng of Pb to the sidestream by smoking. 2. The blood Cd level in the smokers was significantly higher than that in the non-smokers. The urinary Cd level in the smokers was slightly higher than that in the non-smokers. The blood Cd level was related to the number of cigarettes smoked daily. Blood and urinary Pb levels did not differ between the smokers and non-smokers, but the blood Pb level was also related to the number of cigarettes smoked daily. 3. The air Cd levels in smoky places such as the smoking car of the special express train, an office, and a pachinko parlor were markedly higher than that in outdoor air. The air Cd concentration was well correlated with the environmental tobacco smoke concentration. On the other hand, the air Pb level was slightly higher in the above smoky places than outdoors. The mean air Pb concentration was not correlated with the environmental tobacco smoke concentration but was higher at higher environmental tobacco smoke concentration in each place.

    In recent years, attempts have been made to incorporate religion into tobacco control efforts, especially in countries like Malaysia and Thailand where religion is central to the lives of people. This paper is a prospective examination of the perceived relevance and role of religion and religious authorities in influencing smoking behaviour among Muslims in Malaysia and Buddhists in Thailand. Data were collected from 1482 Muslim Malaysian and 1971 Buddhist Thai adult smokers who completed wave 1 (early 2005) of the International Tobacco Control Southeast Asia Survey (ITC-SEA). Respondents were asked about the role of religion and religious leadership on smoking at Wave 1 and among those recontacted, quitting activity at Wave 2. Results revealed that over 90% of both religious groups reported that their religion guides their day-to-day behaviour at least sometimes, but Malaysian Muslims were more likely to report that this was always the case. The majority (79% Muslims and 88% Buddhists) of both groups believed that their religion discourages smoking. About 61% of the Muslims and 58% of the Buddhists reported that their religious leaders had encouraged them to quit before and a minority (30% and 26%, respectively) said they would be an influential source to motivate them to quit. Logistic regression models suggest that these religious factors had a clear independent association with making quitting attempts in both countries and this translated to success for Malaysian Muslims but not for the Thai Buddhists. Taken together, results from this study indicate that religion and religious authorities are both relevant and important drivers of quitting, but whether this is always enough to guarantee success is less clear. Religion can be a culturally relevant vehicle to complement other tobacco control efforts.

    Full Text Available Concentrations of metals Fe, Zn, Cu, Cr, Cd and Ni and their relationship with oxidative stress biomarkers were evaluated in 50 chronic smokers, both females and males (30 to 84 years. Smokers were divided into two groups (1-5 cigarettes/day, 25, and smokers of more than 6 cigarettes/day, 25. Metal concentrations in whole blood and urine were determined by atomic absorption spectrophotometry with inductively coupled (ICP; hematological and biochemical assays were performed to determine total proteins, fractionated proteins and total thiols. Smokers had higher concentrations of Fe regardless of the number of cigarettes smoked and lower concentrations of Zn, Cr and Ni, No di erences were observed in Cu blood concentrations. Smokers show Cd concentrations between 5.0-10.0 μg/L and non-smokers between 0,0-5,0 μg/L. No signi cant di erences were observed in of Hb, Hct and MCHC concentrations, neither albumin and globulins concentrations; an increased in leukocytes and total thiol was observed in smokers. Blood Fe concentrations were correlated with leucocytes and with Cd. Also, it was showed correlation between albumin and thiols. Zn and Cu concentrations were increased in urine of smokers. According to these results, in chronic smokers, the distribution of Fein the body plays a central role in the possible progression and development of diseases related to smoking.

    The decreasing proportion of smokers due to smoking restrictions have led producers to invent and disseminate electronic cigarettes (e-cigarettes) worldwide as a new form of nicotine enjoyment. This review summarizes the existing knowledge about e-cigarettes based on publications of PubMed, and on reviews and research data published by national and international scientific institutions. Present knowledge about the composition of e-cigarettes confirms that they are harmful products since their vapor is equally detrimental to the health of users and bystanders. Their benefits in smoking cessation still have not been justified by adequate scientific evidence, however, it has been proven that e-cigarettes uphold nicotine addiction and may increase the risk of starting conventional cigarette use by youth. In order to ensure the results of tobacco control policy and to assist smoking cessation, the same regulations are to be applied to e-cigarettes as to conventional tobacco products.

    Due to their similarity to tobacco cigarettes, electronic cigarettes (e-cigarettes) could play an important role in tobacco harm reduction. However, the public health community remains divided concerning the appropriateness of endorsing a device whose safety and efficacy for smoking cessation remain unclear. We identified the major ethical considerations surrounding the use of e-cigarettes for tobacco harm reduction, including product safety, efficacy for smoking cessation and reduction, use among non-smokers, use among youth, marketing and advertisement, use in public places, renormalization of a smoking culture, and market ownership. Overall, the safety profile of e-cigarettes is unlikely to warrant serious public health concerns, particularly given the known adverse health effects associated with tobacco cigarettes. As a result, it is unlikely that the population-level harms resulting from e-cigarette uptake among non-smokers would overshadow the public health gains obtained from tobacco harm reduction among current smokers. While the existence of a gateway effect for youth remains uncertain, e-cigarette use in this population should be discouraged. Similarly, marketing and advertisement should remain aligned with the degree of known product risk and should be targeted to current smokers. Overall, the available evidence supports the cautionary implementation of harm reduction interventions aimed at promoting e-cigarettes as attractive and competitive alternatives to cigarette smoking, while taking measures to protect vulnerable groups and individuals.

    Full Text Available Smoking and unhealthy diet are two major risk factors for non-communicable diseases. The aim of this study was to investigate the possible association between these two risk factors amongst healthy adults 30-60 years old in Tehran, Iran.Overall, 2602 healthy adults 30 to 60 years old in Tehran were studied. The demographic characteristics, anthropometric and smoking status of the participants were questioned. The frequency of consumption of red meat, white meat, fruits and vegetables, dairy products, bread and cereals and fast food were questioned to be daily, weekly, monthly, once every 6 months or yearly and categorized as "healthy" or "unhealthy".Of the 2602 participants, 974 (37.4% had smoked more than 100 cigarettes in their life time and continued daily or smoked occasionally. Smokers significantly consumed more fast food and white meat but less fruit and vegetables and dairy product (P<0.0001. Totally, 586 (22.5% consumed "unhealthy" diet. A positive association between cigarette smoking and unhealthy diet (OR=1.68; 95% CI: 1.40-2.03 were found. After adjusting the analysis for the effect of age, education and gender, the odds ratio of consuming unhealthy diet for the smoker increased to 1.83 (1.50, 2.25 compared with non-smoker.Our study found a noticeable association between cigarette smoking and unhealthy diet. Smoking cessation and changing diet program for smokers is recommended.

    Full Text Available To examine prevalence of, and factors associated with, e-cigarette use among young people aged 16-17 in Ireland.In 2014, a representative sample of 821 young people aged 16-17 recruited from secondary schools completed a pen and paper survey on e-cigarette use, tobacco use, and socio-demographic items.A total of 23.8% of respondents had used e-cigarettes at least once. Dual trial of tobacco and e-cigarettes was common with 69.5% of regular smokers and 30.4% of 'ever' smokers having tried e-cigarettes and 10.6% of current smokers using e-cigarettes regularly. 4.2% of never smokers have tried e-cigarettes. Overall, current e-cigarette use (once a month or more was low (3.2%. Binary logistic regression conducted through generalized estimating equations (GEE determined that controlling for other variables, current tobacco use and 'ever' tobacco use predicted ever e-cigarette use. Gender and school-level socioeconomic status were also independent predictors of ever e-cigarette use. Gender stood as the only predictor of on-going e-cigarette use, with males being more likely to regularly use e-cigarettes at least once a month.E-cigarette use among 16-17 year olds in Ireland is of note, with nearly a quarter of students having tried them. Concurrent or experimental use of e-cigarettes and tobacco is more common than sole use, while a small number have tried e-cigarettes without having tried tobacco.

    Smokers' expectancies regarding the effects of cigarette use are powerful predictors of smoking motivation and behavior. However, studies have not investigated the consequences that smokers expect when they attempt to quit smoking: abstinence-related expectancies. The primary goal of this qualitative study was to gain initial insight into smokers' expectancies for abstinence. Eight focus groups were conducted with 30 smokers diverse with respect to age, gender, and ethnoracial background. Content analyses indicated that smokers anticipate a variety of outcomes from abstinence. The most frequently reported expectancies included pharmacologic withdrawal symptoms, behavioral withdrawal symptoms, decreased monetary expense, and immediate improvement of certain aspects of physical functioning and health. Additional expectancies concerned weight gain, improved attractiveness, enhanced social functioning/self-esteem, long-term health outcomes, and loss of relationships. Finally, a number of relatively unheralded expectancies were revealed. These involved nicotine replacement therapy effectiveness, alcohol and other drug use, cue reactivity, cessation-related social support, aversion to smoking, and "political process" implications. This study provides a preliminary step in understanding smokers' expectancies for abstinence from cigarettes. PMID:19586157

    Full Text Available ABSTRACT: BACKGROUND: Smoking is one of the environmental factors which can alter normal lipid profile. It is one of the major risk fa ctors in the genesis of coronary atherosclerosis and development of coronary heart disease. AIMS: To evaluate and compare the lipid profile in both groups and to evaluate the existence of dose de pendent relationship and durational significance between smoking and lipid profile among smokers. SETTINGS AND DESIGN: Out of 100 apparently healthy male subjects of age group 21-4 0yrs, 50 were smokers and 50 were non smokers. All the subjects were non alcoholic, non – obese, normotensives and from same socioeconomic status. Subjects who smoke more than equal 10 cigarettes for more than 2 years were considered as smokers group. METHODS AND MATERIAL: The subjects were asked to fast overnight and early morning blood samples colle cted and analyzed for lipid profile by appropriate methods. STATISTICAL ANALYSIS USED: The student’s unpaired “t” test was used for statistical analysis. P-value of < 0.05 or P va lue <0.01 was considered statistically significant. RESULTS: In our study we found serum TC, TG, LDL and VLDL w ere higher in smokers as compared to non smokers and the serum HDL level was significantly decreased in smokers compared to non smokers showing greater risk of thes e persons to atherosclerosis and coronary heart disease. Conclusions: - We conclude our study with the obser vation that smoking causes alteration in lipid profile. Increased amount and duration of smok ing causes more dyslipidaemia .This alteration in serum lipid levels increases risk for coronary artery disease.

    Full Text Available BACKGROUND: Tobacco smoking is a major contributor to the public health burden and healthcare costs worldwide, but the determinants of smoking behaviours are poorly understood. We conducted a large individual-participant meta-analysis to examine the extent to which work-related stress, operationalised as job strain, is associated with tobacco smoking in working adults. METHODOLOGY AND PRINCIPAL FINDINGS: We analysed cross-sectional data from 15 European studies comprising 166,130 participants. Longitudinal data from six studies were used. Job strain and smoking were self-reported. Smoking was harmonised into three categories never, ex- and current. We modelled the cross-sectional associations using logistic regression and the results pooled in random effects meta-analyses. Mixed effects logistic regression was used to examine longitudinal associations. Of the 166,130 participants, 17% reported job strain, 42% were never smokers, 33% ex-smokers and 25% current smokers. In the analyses of the cross-sectional data, current smokers had higher odds of job strain than never-smokers (age, sex and socioeconomic position-adjusted odds ratio: 1.11, 95% confidence interval: 1.03, 1.18. Current smokers with job strain smoked, on average, three cigarettes per week more than current smokers without job strain. In the analyses of longitudinal data (1 to 9 years of follow-up, there was no clear evidence for longitudinal associations between job strain and taking up or quitting smoking. CONCLUSIONS: Our findings show that smokers are slightly more likely than non-smokers to report work-related stress. In addition, smokers who reported work stress smoked, on average, slightly more cigarettes than stress-free smokers.

    Full Text Available Abstract Background Undiagnosed airflow limitation is common in the general population and is associated with impaired health and functional status. Smoking is the most important risk factor for this condition. Although primary care practitioners see most adult smokers, few currently have spirometers or regularly order spirometry tests in these patients. Brief medical advice has shown to be effective in modifying smoking habits in a large number of smokers but only a small proportion remain abstinent after one year. The aim of this study is to evaluate the effectiveness of regular reporting of spirometric results combined with a smoking cessation advice by a primary care physician on smoking quit rate in adult smokers. Methods/design Intervention study with a randomized two arms in 5 primary care centres. A total of 485 smokers over the age of 18 years consulting their primary care physician will be recruited. On the selection visit all participants will undergo a spirometry, peak expiratory flow rate, test of smoking dependence, test of motivation for giving up smoking and a questionnaire on socio-demographic data. Thereafter an appointment will be made to give the participants brief structured advice to give up smoking combined with a detailed discussion on the results of the spirometry. After this, the patients will be randomised and given appointment for follow up visits at 3, 6, 12 and 24 months. Both arms will receive brief structured advice and a detailed discussion of the spirometry results at visit 0. The control group will only be given brief structured advice about giving up smoking on the follow up. Cessation of smoking will be tested with the carbon monoxide test. Discussion Early identification of functional pulmonary abnormalities in asymptomatic patients or in those with little respiratory symptomatology may provide "ideal educational opportunities". These opportunities may increase the success of efforts to give up smoking and

    Tobacco or better known as the cigarette was smoked since ages. Although many efforts had been made by the Ministry of Health to prevent or reduce the cigarette problem, the smokers still consider that cigarette are not harmful to health. This work is conducted to study the concentration of radionuclides alpha in tobacco and tobacco products in Malaysia. The radionuclide sought in this study is 210Po which is an alpha emitter. The sample used are tobacco and cigarettes, the tobacco samples were taken from tobacco farms in Malaysia while the sample branded cigarettes Marlboro and Gudang Garam were bought in the supermarket. The objectives of this study are to determine the concentration of radionuclides 210Po in tobacco and tobacco products as well as to estimate the radioactivity doses contributing to the smokers in Malaysia. The results for Marlboro cigarettes and Gudang Garam were found to be on the average radionuclide concentration of 210Po is 13.3 mBq/g (Marlboro cigarettes) and 11.9 mBq/g (Gudang Garam). From the total concentration of the cigarette, the estimated annual contribution dose to smokers for every 20 cigarettes smoked per day are 111.9 ± 14.7 μSv/year for Marlboro cigarettes and 100.2 ± 3.3 μSv/year for Gudang Garam cigarettes. The average concentration of radionuclides for tobacco leaf tobacco for each area taken is 3.6 mBq / g for Bachok, 2.4 mBq / g for Tumpat and 3.1 mBq / g for Semerak district.

    Loneliness is common in persons living with HIV (PLWH). Lonely people smoke at higher rates than the general population, and loneliness is a likely contributor to the ongoing smoking epidemic among PLWH. We explored factors associated with loneliness in a cohort of 272 PLWH smokers enrolled in two separate tobacco treatment trials. Loneliness was independently associated with lack of a spouse or partner, lower educational attainment, "other or unknown" HIV exposure category, depression, anxiety, recent alcohol consumption, and higher daily cigarette consumption. Referral to group therapy reduced loneliness, whereas referral to an individual web-based tobacco treatment did not.

    Full Text Available Aims: The aim of this study was to assess the effect of tobacco smoking on gingival health and the oral hygiene status of respondents. Materials and Methods: A cross-sectional survey of 213 adults from three communities in the Ibadan North local government was carried out. Respondents were divided into two groups comprising of 117 smokers (cases and 96 non-smokers (control. Intra oral examination was done using the Simplified Oral Hygiene Index (OHI-S and Gingival index (GI. Results: The mean age of the smokers was 31.2 ± 12.6 years and that of the non-smokers 32.8 ± 9.5 years. The mean Simplified Oral Hygiene Index (OHI-S was 1.15 ± 0.51 for the non-smokers and 2.19 ± 0.62 for the smokers (P < 0.05. The mean GI was 1.06 ± 0.55 for the non-smokers and 1.62 ± 0.58 for the smokers (P < 0.05. Conclusion: The study shows that smoking is associated with increased severity of gingival disease. It is, therefore, recommended that smokers should be encouraged to visit a dentist for preventive procedure more regularly than the non-smokers and better still, smokers should be encouraged to quit smoking as gingival disease is not without consequences if allowed to persist.

    This paper empirically studies time inconsistent preferences in the context of cigarette smoking behavior. With hyperbolic discounting, an individual has time inconsistent preferences, which give rise to a lack of self-control, i.e., she may perpetually postpone the execution of a plan. This implies that a smoker who wants to quit has a demand for control devices, e.g., a smoking ban in public areas or a hike in cigarette excise taxes. This paper empirically tests this implication, using a sa...

    Impaired response inhibition plays a major role in many addictive behaviors. However, in studies using go/no-go tasks, findings regarding the presence of response inhibition deficits in nicotine-dependent individuals are mixed. This might be due to differences between studies on a number of task parameters. Here we aimed to identify task conditions under which go/no-go task performance deficits can be observed in smokers and to characterize the nature of such deficits. Sixty-one male students (30 smokers, 31 non-smokers) performed a go/no-go task while independently manipulating three task parameters: (1) percentage no-go trials (50% or 25%), (2) stimulus presentation time (600 ms or 200 ms), and (3) nature of no-go stimuli (cigarette related or cigarette unrelated). Three measures, reaction time on go trials and percentage correct responses on go and no-go trials, served as performance indicators. Under 200-ms but not 600-ms stimulus presentation conditions, the smokers responded faster on go trials and made more errors on both go and no-go trials than the non-smokers did. These differences occurred irrespective of the percentage of no-go trials and nature of no-go stimuli. The accuracy differences disappeared after controlling for the response time differences, suggesting a strong speed-accuracy trade-off. This study contributes to unraveling the conditions under which smokers display impaired inhibition performance and helps to characterize the nature of this impairment. Under task conditions prompting fast responding, smokers are more prone to increase response speed and to make more errors than non-smokers. PMID:27500831

    This study aims at examine the effect of cigarettes smoking on paraoxonase 1 (PON1) activity and lipid profile. Our study included 102 smokers aged 35.5 +/- 16.0 years and 98 non-smokers aged 38.5 +/- 21.9 years. Total cholesterol (TC), triacylglycerols (TG), HDL cholesterol (CHDL) and LDL-cholesterol (cLDL) were determined by enzymatic colorimetric methods. ApoA1 and ApoB and Lp(a) were analyzed by immunoturbidimetry on Konélab 30, PON1 activity was measured by a kinetic method. Plasma CT, TG, cLDL, Lp(a) and ApoB/ApoA1 ratio appeared significantly higher in the smokers when compared to nonsmokers, since cHDL levels were lower. In addition, TG values were significantly higher in subjects smoking more than 30 cigarettes/day as compared to those smoking 5-10 cigarettes/day. We noted a significant decrease of PON1 activity in smokers compared to non smokers (94 +/- 104 vs 158 +/- 133 IU/L), with regression of PON1 activity according number of cigarettes/day. In conclusion, hypertriglyceridemia, low levels of cHDL, high levels of ApoB/ApoA1 and significant decrease of PON1 activity confirm the high risk of cardiovascular diseases in smokers.

    Teenage cigarette smoking is sensitive to the price of cigarettes. The most recent research suggests that a 10% increase in price would reduce the number of teenagers who smoke by 7%. If the proposed 43-cent hike in the Federal excise tax rate on cigarettes contained in the Hatch-Kennedy Bill were enacted, the number of teenage smokers would fall by approximately 16%. This translates into more than 2.6 million fewer smokers and more than 850,000 fewer smoking-related premature deaths in the current cohort of 0 to 17-year-olds. Adjusted for inflation, the current 24-cent-a-pack tax costs the buyer about half of the original cigarette tax of 8 cents imposed in 1951. A substantial tax hike would curb youth smoking; this strategy should move to the forefront of the antismoking campaign. PMID:9258294

    Full Text Available Introduction: A strong relationship exists between cigarette smoking and the development of oral squamous cell carcinoma. Smoking can significantly increase cellular proliferation. Nevertheless, there is little reference in literature to the cytological assessment of oral mucosa in this respect. Methods: Changes in nuclear and neucleolar cytomorphometric parameters such as diameter, surface, number and color intensity, in cytologic smears which were collected from normal buccal mucosa of 30 cigarette smokers and 30 non smokers, using methyl green-pyronin staining were studied. Results: Our findings attested to smoking as significant inductive factor in cytochemistry as well as morphologic changes. Conclusion: This technique is a valuable tool.

    Aim To examine the association of socio-economic position (education, income and employment status) with cigarette consumption, intention to quit and self-efficacy to quit among male smokers in Thailand and Malaysia. Design and setting The data were based on a survey of adult smokers conducted in early 2005 in Thailand and Malaysia as part of the International Tobacco Control-South-East Asia (ITC-SEA) project. Participants A total of 1846 men in Thailand and 1906 men in Malaysia. Measurement Participants were asked questions on daily cigarette consumption, intention to quit and self-efficacy to quit in face-to-face interviews. Findings Analyses were based on multivariate regression models that adjusted for all three socio-economic indicators. In Thailand, higher level of education was associated strongly with not having self-efficacy, associated weakly with having an intention to quit and was not associated with cigarette consumption. Higher income was associated strongly with having self-efficacy, associated weakly with high cigarette consumption and was not associated with having an intention to quit. Being employed was associated strongly with having an intention to quit and was not associated with cigarette consumption or self-efficacy. In Malaysia, higher level of education was not associated with any of the outcomes. Higher income was associated strongly with having self-efficacy, and was not associated with the other outcomes. Being employed was associated moderately with higher cigarette consumption and was not associated with the other outcomes. Conclusion Socio-economic and cultural conditions, as well as tobacco control policies and tobacco industry activities, shape the determinants of smoking behaviour and beliefs. Existing knowledge from high-income countries about disparities in smoking should not be generalized readily to other countries. PMID:18269370

    Full Text Available Background: Acne vulgaris is a common chronic inflammatory disease of pilosebaceous unit. Different factors have been suggested to influence acne including diet, menstruation and occupation. The role of some of these factors on acne intensity is confirmed. The affect of Cigarette smoking on acne intensity has been suggested. In this research, we evaluated the association between cigarette smoking and the acne intensity.Materials and Methods: This cross-sectional study was performed on 278 smoker and 277non smoker males referred to dermatology clinics of Semnan during 2006-2007. The dermatologists interviewing the patients completed questionnaires based on clinical diagnosis and intensity of acne. Data analysis was performed using t-test, Mann-Whitney, Chi-square and Spearman coefficient tests. P-value less than 0.05 were considered significant. Results: Severe acne was observed in 16.6% of non-smokers and 22.7% of smokers. Distribution of acne intensity in both groups was significant (P=0.023. Association between duration of cigarette smoking and acne intensity was significant too (P<0.001. The association between dosage of cigarette smoking and acne intensity was also significant (P<0.001.Conclusion: Significant association between cigarette smoking and acne intensity showed that smoking withdrawal is helpful for reducing the acne intensity

    A procedure based on the use of ion mobility spectrometry (IMS), after liquid-liquid microextraction (LLME), has been successfully employed for the determination of passive exposure to nicotine from cigarette and e-cigarette smoking. Nicotine has been determined in exhaled breath and oral fluids of both, active and passive smokers. The aforementioned studies, made in closed environments, evidenced that the exhaled breath after conventional blend cigarette smoke provides nicotine levels of the order of 220 ng per puff, in the case of experienced smokers, being exhaled only 32 ng in the case of e-cigarettes. On the other hand, the nicotine amount in oral fluids of passive vapers was between 8 and 14 µg L(-1) lower than the average value of 38±14 µg L(-1) found for passive smokers of rolling tobacco and clearly lower than the 79±36 µg L(-1) obtained from passive smokers of classical yellow blend. This study was also placed in the frame of the verification of the e-cigarettes composition. PMID:26992528

    Freeman, Allison

    This research examined the fundamental frequency and perturbation (jitter % and shimmer %) measures in young adult (20-30 year-old) and middle-aged adult (40-55 year-old) smokers and non-smokers; there were 36 smokers and 36 non-smokers. Acoustic analysis was carried out utilizing one task: production of sustained /a/. These voice samples were analyzed utilizing Multi-Dimensional Voice Program (MDVP) software, which provided values for fundamental frequency, jitter %, and shimmer %.These values were analyzed for trends regarding smoking status, age, and gender. Statistical significance was found regarding the fundamental frequency, jitter %, and shimmer % for smokers as compared to non-smokers; smokers were found to have significantly lower fundamental frequency values, and significantly higher jitter % and shimmer % values. Statistical significance was not found regarding fundamental frequency, jitter %, and shimmer % for age group comparisons. With regard to gender, statistical significance was found regarding fundamental frequency; females were found to have statistically higher fundamental frequencies as compared to males. However, the relationships between gender and jitter % and shimmer % lacked statistical significance. These results indicate that smoking negatively affects voice quality. This study also examined the ability of untrained listeners to identify smokers and non-smokers based on their voices. Results of this voice perception task suggest that listeners are not accurately able to identify smokers and non-smokers, as statistical significance was not reached. However, despite a lack of significance, trends in data suggest that listeners are able to utilize voice quality to identify smokers and non-smokers.

    Full Text Available Cigarette smoke is a known source of exposure to carcinogenic polycyclic aromatic hydrocarbons (PAHs, especially benzo[a]pyrene (BaP. Exposure to BaP in cigarette smoke is influenced by how a person smokes and factors, such as tobacco blend. To determine whether sustained use of reduced-nicotine cigarettes is associated with changes in exposure to nicotine and BaP, levels of BaP in spent cigarette filter butts were correlated with levels of BaP in cigarette smoke to estimate mouth-level intake (MLI of BaP for 72 daily smokers given three progressively reduced nicotine content cigarettes. Urinary cotinine, a marker of nicotine exposure, and urinary 1-hydroxypyrene (1-HOP, a marker of PAH exposure, were measured throughout the study. Median daily BaP MLI and urine cotinine decreased in a similar manner as smokers switched to progressively lower nicotine cigarettes, despite relatively constant daily cigarette consumption. 1-HOP levels were less responsive to the use of reduced nicotine content cigarettes. We demonstrate that spent cigarette filter butt analysis is a promising tool to estimate MLI of harmful chemicals on a per cigarette or per-day basis, which partially addresses the concerns of the temporal influence of smoking behavior or differences in cigarette design on exposure.

    Full Text Available INTRODUCTION: There is a clear relationship between the amount of cigarette smoked and mortality. Ironically there is also an increased incidence of cigarette smoking in women all over the world with an increased risk of spontaneous abortion in pregnant women. Although exposure is small as compared with that experienced by mainstream smokers, non - smoking passive smokers, who are in the same room may show pulmonary deposition of smoke particles as well as increased blood levels of nicotine and carboxyhaemoglobin, which became dangerous for infant and children. Smoking cessation is usually associate with improvement of lung functions, that can returns to normal over a period of time. AIMS: To compare the efficiency of lung function in active smokers, passive smokers and after cessation of smoking. MATERIALS AND METHODS: 200 subjects with various age groups ranging from less than 20 years upto 60 years, selected from the relative and attendants of patients attending the outpatient department and indoor wards. They were divided into study and control group. Their lung func tions were tested by spirometry with the help of Medispiror. The results obtained were analyzed statistically. STATISTICAL ANALYSIS: the statistical analysis was done by using the formulas of two tail t test. RESULT: There is a highly significant (p0.05. CONCLUSION: All the pulmonary functions get worse because of smoking and even passive smoking, which can come back to normal (as in non - smoker after cessation of smoking, whic h is a true fact for both the genders.

    Full Text Available BACKGROUND: Some smokeless tobacco products (SLT have been shown to be associated with only a fraction of the risks of cigarettes. This study assessed South African smokers' interest in switching to a hypothetical reduced harm SLT product. METHODS: The 2007 South African Social Attitudes Survey was analysed for 678 exclusive cigarette smokers. Respondents were asked about their perceptions about relative harm of snuff compared to cigarettes, and their interest in switching to snuff if informed it was 99% less harmful than cigarettes. RESULTS: About 49.7% of exclusive cigarette smokers believed that snuff was equally as harmful as cigarettes; 12.9% thought snuff was more harmful; 5.7% thought snuff was less harmful; while 31.8% did not know if there was a difference in harm between snuff and cigarettes. Approximately 24.2% of exclusive cigarette smokers indicated interest in switching to snuff, with significantly greater interest observed among those exposed to 100% smoke-free work environment. Interest in switching was highest (34.7% among smokers who believed a priori that using snuff was more harmful than cigarettes, and lowest (14.5% among those who did not know if there was a difference in harm. In a multi-variable adjusted logistic regression model, this latter group remained less likely to be interested in harm reduction switching (adjusted odds ratio = 0.42; 95% CI: 0.19-0.91. CONCLUSION: About a quarter of smokers indicated interest in harm reduction switching to snuff. SLT products have a potential role in reducing the harm from smoking in South Africa, but only if they are not used to circumvent smoke-free laws that have been associated with reduced smoking.

  9. Motion and twisting of magnetic particles ingested by alveolar macrophages in non-smokers and smokers: Implementation of viscoelasticity

    International Nuclear Information System (INIS)

    Ferrimagnetic iron oxide particles were inhaled by 17 healthy volunteers (9 non-smokers, 8 smokers), and the retained particles were magnetized and detected by a SQUID. Stochastic particle transport due to cytoskeletal reorganizations within macrophages (relaxation) and directed particle motion in a weak magnetic twisting field were investigated with respect to viscous and elastic properties of the cytoskeleton. Relaxation and cytoskeletal stiffness were not influenced by cigarette smoking. Relaxation and particle twisting revealed a non-Newtonian viscosity with a pure viscous and a viscoelastic compartment. Viscous and elastic data obtained from relaxation correlated with particle twisting, indicating that the proposed simple model is a reasonable approximation of cytoskeletal mechanical properties

    The purpose of the present study is to examine the relation between magazine advertising for cigarettes and adolescent cigarette smoking. Participants (242 adolescents) reported their frequency of reading 46 magazines and their attention to cigarette ads. Recognition of cigarette ads, passive peer pressure (i.e., normative beliefs), and the smoker image also were assessed. Results indicate that exposure to cigarette advertising and recognition of ads augment the effect of passive peer pressure on smoking. In addition, a positive smoker image was associated with attention to advertising and mediated the relation between attention and smoking. It is suggested that the effect of magazine ads on adolescents should be considered in policymaking on cigarette advertising. PMID:16624795

    We employed a time series design to evaluate the impact of the 1989 California cigarette tax increase on cigarette consumption in California. Adult per capita consumption data from 1980 to 1990 were analyzed for California and the United States. Trend data indicated a sharp drop in California cigarette consumption coincident with the tax increase. Time-series regression analyses support this observation, and suggest that a 5% to 7% decline in consumption is attributable to the tax increase.

  15. Cigarettes Butts and the Case for an Environmental Policy on Hazardous Cigarette Waste

    Directory of Open Access Journals (Sweden)

    2009-05-01

    Full Text Available Discarded cigarette butts are a form of non-biodegradable litter. Carried as runoff from streets to drains, to rivers, and ultimately to the ocean and its beaches, cigarette filters are the single most collected item in international beach cleanups each year. They are an environmental blight on streets, sidewalks, and other open areas. Rather than being a protective health device, cigarette filters are primarily a marketing tool to help sell ‘safe’ cigarettes. They are perceived by much of the public (especially current smokers to reduce the health risks of smoking through technology. Filters have reduced the machine-measured yield of tar and nicotine from burning cigarettes, but there is controversy as to whether this has correspondingly reduced the disease burden of smoking to the population. Filters actually may serve to sustain smoking by making it seem less urgent for smokers to quit and easier for children to initiate smoking because of reduced irritation from early experimentation. Several options are available to reduce the environmental impact of cigarette butt waste, including developing biodegradable filters, increasing fines and penalties for littering butts, monetary deposits on filters, increasing availability of butt receptacles, and expanded public education. It may even be possible to ban the sale of filtered cigarettes altogether on the basis of their adverse environmental impact. This option may be attractive in coastal regions where beaches accumulate butt waste and where smoking indoors is increasingly prohibited. Additional research is needed on the various policy options, including behavioral research on the impact of banning the sale of filtered cigarettes altogether.

    Smoking abstinence differentially affects cognitive functioning in smokers with ADHD, compared to non-ADHD smokers. Alternative approaches for analyzing reaction time data from these tasks may further elucidate important group differences. Adults smoking ≥15 cigarettes with (n = 12) or without (n = 14) a diagnosis of ADHD completed a continuous performance task (CPT) during two sessions under two separate laboratory conditions—a ‘Satiated’ condition wherein participants smoked up to and during the session; and an ‘Abstinent’ condition, in which participants were abstinent overnight and during the session. Reaction time (RT) distributions from the CPT were modeled to fit an ex-Gaussian distribution. The indicator of central tendency for RT from the normal component of the RT distribution (mu) showed a main effect of Group (ADHD Satiated), Group × Session interaction (ADHD increased significantly under Abstinent condition compared to Control), and a trend toward a main effect of Group (ADHD > Control). Alternative approaches to analyzing RT data provide a more detailed description of the effects of smoking abstinence in ADHD and non-ADHD smokers and results differ from analyses using more traditional approaches. These findings have implications for understanding the neuropsychopharmacology of nicotine and nicotine withdrawal. PMID:19041198

    Full Text Available E-cigarettes are emerging products, often described as “reduced-risk” nicotine products or alternatives to combustible cigarettes. Many smokers switch to e-cigarettes to quit or significantly reduce smoking. However, no regulations for e-cigarettes are currently into force, so that the quality and safety of e-liquids is not necessarily guaranteed. We exposed primary human bronchial epithelial cells of two different donors to vapor of e-cigarette liquid with or without nicotine, vapor of the carrier substances propylene glycol and glycerol as well as to mainstream smoke of K3R4F research cigarettes. The exposure was done in a CULTEX® RFS compact  module, allowing the exposure of the cells at the air-liquid interface. 24 h post-exposure, cell viability and oxidative stress levels in the cells were analyzed. We found toxicological effects of e-cigarette vapor and the pure carrier substances, whereas the nicotine concentration did not have an effect on the cell viability. The viability of mainstream smoke cigarette exposed cells was 4.5–8 times lower and the oxidative stress levels 4.5–5 times higher than those of e-cigarette vapor exposed cells, depending on the donor. Our experimental setup delivered reproducible data and thus provides the opportunity for routine testing of e-cigarette liquids to ensure safety and quality for the user.

    Cadmium has been determined in 26 brands of cigarettes purchased in eight different countries throughout the world and in 16 different samples of cigarettes produced in Sweden between 1918 and 1968. In addition the amount of cadmium released from smoking one cigarette to the particulate phase collected from a smoking simulation machine, corresponding to the amount actually inhaled by a smoker, has been determined. The cadmium concentration in different brands of cigarettes ranged from 0.19 to 3.0 micrograms Cd/g dry wt, with a general tendency toward lower values in cigarettes from developing countries. No systematic change in the cadmium concentration of cigarettes with time could be revealed. The amount of cadmium inhaled from smoking one cigarette containing about 1.7 microgram Cd was estimated to be 0.14 to 0.19 microgram, corresponding to about 10% of the total cadmium content in the cigarette.

    This study investigated the relationship between the total amount of cigarettes smoked (TACS) and indoor air pollution, with the risk of COPD among urban and rural Chinese adults. A nested case-control study was performed using data collected in a large community survey (N = 29 319) conducted between October 2000 and March 2001 in Nanjing, China. The exposure to indoor respiratory pollutants of cooking and heating materials and to passive cigarette smoke was compared in patients diagnosed with COPD (n = 1743) and controls matched for age, gender and residence (n = 1743). The smoking rate among COPD patients was significantly higher than that among the controls. After controlling for possible confounders, the adjusted odds ratios for COPD increased across TACS tertiles: from lower (OR = 1.40, 95% confidence interval (CI): 1.09-1.79), to middle (OR = 1.55, 95% CI: 1.21-1.99), and upper (OR = 1.77, 95% CI: 1.37-2.29). Among smokers, women were significantly more likely to develop COPD than men (OR = 1.20, 95% CI: 1.02-1.41). There were no significant associations between COPD and domestic fuels used, kitchen ventilation or passive smoking. Heating in winter with coal was weakly but positively linked with COPD among non-smokers overall, among women non-smokers, and specifically for women living in urban as well as rural areas. This clear dose-response relationship exists between cigarette smoking and COPD; compared with men, women smokers were more susceptible to COPD. Exposure to other respiratory pollutants in the home was not significantly associated with the diagnosis of COPD.

    CT scans were performed in 11 cases of respiratory bronchiolitis caused by cigarette smoking. Characteristics of CT findings were as follows: Remarkable visualization of the branching in peripheral bronchi within secondary lobules, multiple ground-glass opacities of centrilobular or lobular size adjacent to the above mentioned bronchial branching, thickening of the bronchial wall without dilatation, and no or minimal centrilobular emphysema. These characteristic CT findings were observed in all of 11 cases, who are current smokers, and never observed in non-smokers, ex-smokers and patients with apparent centrilobular emphysema. (author)

  6. Successful Nicotine Intake in Medical Assisted Use of E-Cigarettes: A Pilot Study

    Full Text Available The electronic cigarette (e-cig has gained popularity as an aid in smoking cessation programs mainly because it maintains the gestures and rituals of tobacco smoking. However, it has been shown in inexperienced e-cig users that ineffective nicotine delivery can cause tobacco craving that could be responsible for unsuccessful smoking reduction/cessation. Moreover, the incorrect use of an e-cig could also led to potential nicotine overdosage and intoxication. Medically assisted training on the proper use of an e-cig plus behavioral support for tobacco dependence could be a pivotal step in avoiding both issues. We performed an eight-month pilot study of adult smokers who started e-cig use after receiving a multi-component medically assisted training program with monitoring of nicotine intake as a biomarker of correct e-cig use. Participants were tested during follow-up for breath carbon monoxide (CO, plasma cotinine and trans-3’-hydroxycotinine, and number of tobacco cigarettes smoked. At the end of the first, fourth, and eighth month of follow-up, 91.1, 73.5, and 76.5% of participants respectively were e-cig users (‘only e-cig’ and ‘dual users’. They showed no significant variation in plasma cotinine and trans-3’-hydroxycotinine with respect to the start of the study when they smoked only tobacco cigarettes, but a significant reduction in breath CO. The proposed medically assisted training program of e-cig use led to a successful nicotine intake, lack of typical cigarette craving and overdosage symptoms and a significant decrease in the biomarker of cigarette combustion products.

    Perceived ethnic discrimination has been associated with cigarette smoking in US adults in the majority of studies, but gaps in understanding remain. It is unclear if the association of discrimination to smoking is a function of lifetime or recent exposure to discrimination. Some sociodemographic and mood-related risk factors may confound the relationship of discrimination to smoking. Gender and race/ethnicity differences in this relationship have been understudied. This study examines the relationship of lifetime and recent discrimination to smoking status and frequency, controlling for sociodemographic and mood-related variables and investigating the moderating role of race/ethnicity and gender. Participants included 518 Black and Latino(a) adults from New York, US. Lifetime and past week discrimination were measured with the Perceived Ethnic Discrimination Questionnaire-Community Version. Ecological momentary assessment methods were used to collect data on smoking and mood every 20 min throughout one testing day using an electronic diary. Controlling for sociodemographic and mood-related variables, there was a significant association of recent (past week) discrimination exposure to current smoking. Lifetime discrimination was associated with smoking frequency, but not current smoking status. The association of recent discrimination to smoking status was moderated by race/ethnicity and gender, with positive associations emerging for both Black adults and for men. The association of lifetime discrimination on smoking frequency was not moderated by gender or race/ethnicity. Acute race/ethnicity-related stressors may be associated with the decision to smoke at all on a given day; whereas chronic stigmatization may reduce the barriers to smoking more frequently.

    The carcinogenic effect of {sup 210}Po and {sup 210}Pb with respect to lung cancer is an important problem in many countries with very high cigarette consumption. Poland has one of the highest consumptions of cigarettes in the world. The results of {sup 210}Po determination on the 14 most frequently smoked brands of cigarettes which constitute over 70% of the total cigarette consumption in Poland are presented and discussed. Moreover, the polonium content in cigarette smoke was estimated on the basis of its activity in fresh tobaccos, ash, fresh filters and post-smoking filters. The annual effective doses were calculated on the basis of {sup 210}Po and {sup 210}Pb inhalation with the cigarette smoke. The results of this work indicate that Polish smokers who smoke one pack (20 cigarettes) per day inhale from 20 to 215 mBq of {sup 210}Po and {sup 210}Pb each. The mean values of the annual effective dose for smokers were estimated to be 35 and 70 {mu}Sv from {sup 210}Po and {sup 210}Pb, respectively. For persons who smoke two packs of cigarettes with higher radionuclide concentrations, the effective dose is much higher (471 {mu}Sv yr{sup -1}) in comparison with the intake in diet. Therefore, cigarettes and the absorption through the respiratory system are the main sources and the principal pathway of {sup 210}Po and {sup 210}Pb intake of smokers in Poland.

    The current study assessed antecedents and consequences of ad lib cigarette smoking in smokers diagnosed with attention-deficit/hyperactivity disorder (ADHD) using ecological momentary assessment (EMA). Adult smokers with ADHD (n = 17) completed 870 smoking and 622 nonsmoking electronic diary entries over a 7-day observation period of their naturalistic smoking behavior. Data collection occurred from 2011 to 2012. Generalized estimating equations indicated that ADHD smokers were more likely to smoke when urge to smoke, negative affect, boredom, stress, worry, and restlessness were elevated. In addition, participants were more likely to smoke in situations that elicited higher levels of nervousness and frustration. ADHD symptoms, in general, did not differ between smoking and nonsmoking contexts, though hyperactive-impulsive ADHD symptoms were elevated prior to smoking in frustrating situations. Additional situational antecedent variables were associated with smoking, including being in the presence of others smoking, being in a bar or restaurant, while outside, and while consuming caffeinated or alcoholic beverages. Participants also reported a significant improvement in urge to smoke, negative affect, stress, hunger, and ADHD symptoms after smoking a cigarette. Findings suggest certain contextual factors that may maintain ad lib cigarette smoking in smokers with ADHD and identify potential treatment targets in smoking cessation interventions for this at-risk group. Clinical implications and future research directions are discussed. Funding for this study was provided by the National Institute on Drug Abuse.

    Cigarette smoking is a leading cause of preventable morbidity and mortality in the United States. Although public policies have resulted in a decreased number of new smokers, smoking rates remain stubbornly high in certain demographics with 20% of all American middle-aged men smoking. In addition to the well-established harmful effects of smoking (i.e. coronary artery disease and lung cancer), the past three decades have led to a compendium of evidence being compiled into the development of a relationship between cigarette smoking and erectile dysfunction. The main physiologic mechanism that appears to be affected includes the nitric oxide signal transduction pathway. This review details the recent literature linking cigarette smoking to erectile dysfunction, epidemiological associations, dose dependency and the effects of smoking cessation on improving erectile quality.

    Full Text Available Numerous studies have identified specific body systems affected by the hazardous effects of the cigarette smoking particularly the respiratory and cardiovascular systems. The effect of smoking on male reproduction has also been studied where semen quality was investigated in different cross-sectional studies including infertile patients with conflicting results. This article aimed to assess the relationship between smoking and male infertility. A review of published articles was carried out, using PubMed, medical subject heading (MSH databases and Scopus engine excluding the effects of smoking outside male infertility. Key words used to assess exposure, outcome, and estimates for the concerned associations were: smoking, semen, male infertility, sperm, humans, and fertility. Most of the reports showed that smoking reduces sperm production, sperm motility, sperm normal forms and sperm fertilising capacity through increased seminal oxidative stress and DNA damage. Few papers reported nonsignificant differences in semen parameters between smokers or non-smokers. It is concluded that although some smokers may not experience reduced fertility, men with marginal semen quality can benefit from quitting smoking.

    Recent studies have shown that alveolar macrophages (AM) are able to release leukotrienes (LTs). Since cigarette smoking inhibits the cyclooxygenase pathway of arachidonic acid metabolism in the AM, we evaluated the LT production by AM from smokers and nonsmokers. AM were obtained from 35 volunteers, 16 nonsmokers, and 19 smokers. The cells were incubated under various conditions including stimulation with 30 microM arachidonic acid, 2 microM ionophore A23187, or both. Each experiment was per...

    Adolescents obtain cigarettes from both commercial and social sources. While the relationship between commercial access and adolescent smoking has been researched, no one has considered in detail whether rates of peer smoking affect cigarette availability. In two relatively deprived Scottish schools that differed in their pupil smoking rates, we assess pupil access to cigarettes. 896 13 and 15 year olds were surveyed, and 25 single-sex discussion groups held with a sub-sample of the 13 year olds. Smokers in both schools obtained cigarettes from shops, food vans and other pupils. However, pupils in the 'high' smoking school perceived greater access to both commercial and social sources, and had access to an active 'peer market'. These findings suggest that variations in cigarette access may contribute to school differences in pupil smoking rates, and that the relationship between access and adolescent smoking is circular, with greater availability increasing rates, and higher rates enhancing access.

    The U.S. Food and Drug Administration revealed new pictorial warning labels in June 2011 for cigarette packages, yet little is known about how these labels are perceived by U.S. residents. We examined the reactions to and attitudes about the new labels among residents of Appalachian Ohio, a region with a high smoking prevalence. We conducted focus groups with Appalachian Ohio residents between July and October 2011. Participants included healthcare providers (n = 30), community leaders (n = 26), parents (n = 28), and young adult men ages 18-26 (n = 18). Most participants supported the addition of the new labels to U.S. cigarette packages, though many were unaware of the labels prior to the focus groups. Participants did not think the labels would be effective in promoting smoking cessation among smokers in their communities, but they were more positive about the potential of the labels to reduce smoking initiation. Participants reported positive feedback about the more graphic labels, particularly those showing a man with a tracheal stoma or a person with severe oral disease. The labels that include a cartoon image of an ill infant and a man who quit smoking received the most negative feedback. Participants generally supported adding pictorial warning labels to U.S. cigarette packages, but only a few of labels received mostly positive feedback. Results offer early insight into how the new labels may be received if they are put into practice. PMID:22527659

    Full Text Available Introduction The exact mechanisms by which smoking effects the periodontal tissues are not known. Studies in which plaque or calculus are taken into consideration come to conflicting conclusions regarding effects of smoking. Aim The aim of this study was to examine the oral hygiene and periodontal status in smokers and compare them with nonsmokers. Material and methods The study group comprised 83 smokers and 83 nonsmokers. The mean age (SD of smokers and nonsmokers was 42,4±7,0 years and 43,7±6,4 years, respectively. The age difference was not statistically significant. The average tobacco consumption of the smokers at the time of investigation was 14 cigarettes a day and they had been regular smokers for 21 years on average. Results The amount of dental plaque was evaluated in accordance with the criteria of Green-Vermillion by using disclosing solution. The periodontal condition was evaluated by Ramfjord Periodontal Disease Index. For gingival recession the distance from the cemento-enamel junction to the gingival margin was determined on mid-buccal and mid-lingual surfaces of all teeth. Each subject was radiographically examined with a full mouth intraoral survey. Alveolar bone loss was determined as the distance from the cemento-enamel junction to the point where lamina dura became continuous with the compact bone of the interdental septum. Mean alveolar bone loss based on all mesial and distal measurements was calculated for each subject. The amount of dental plaque was high in both smokers (2,60,60 and nonsmokers (1,50,70, whereas the differences were statistically significant (p<0.001. Conclusion Periodontal destruction, alveolar bone loss and gingival recession were significantly increased in smokers compared to nonsmokers (p<0.001. It is concluded that differences observed between smokers and nonsmokers with regard to periodontal condition are attributable to differences in oral hygiene. Smoking is a risk factor for periodontal

    Rationale Individuals with attention deficit hyperactivity disorder (ADHD) have a more difficult time quitting smoking compared to their non-ADHD peers. Little is known about the underlying behavioral mechanisms associated with this increased risk. Objectives This study aims to assess the effects of 24-h smoking abstinence in adult smokers with and without ADHD on the following outcomes: smoking-reinforced responding, withdrawal, and cognitive function. Methods Thirty-three (n=16 with ADHD, 17 without ADHD) adult smokers (more than or equal to ten cigarettes/day) were enrolled. Each participant completed two experimental sessions: one following smoking as usual and one following biochemically verified 24-h smoking abstinence. Smoking-reinforced responding measured via a progressive ratio task, smoking withdrawal measured via questionnaire, and cognition measured via a continuous performance test (CPT) were assessed at each session. Results Smoking abstinence robustly increased responding for cigarette puffs in both groups, and ADHD smokers responded more for puffs regardless of condition. Males in both groups worked more for cigarette puffs and made more commission errors on the CPT than females, regardless of condition. Smoking abstinence also increased ratings of withdrawal symptoms in both groups and smokers with ADHD, regardless of condition, reported greater symptoms of arousal, habit withdrawal, and somatic complaints. Across groups, smoking abstinence decreased inhibitory control and increased reaction time variability on the CPT. Abstinence-induced changes in inhibitory control and negative affect significantly predicted smoking-reinforced responding across groups. Conclusions Smokers with ADHD reported higher levels of withdrawal symptoms and worked more for cigarette puffs, regardless of condition, which could help explain higher levels of nicotine dependence and poorer cessation outcomes in this population.

    The use of electronic cigarettes (e-cigarettes) among adults in the Netherlands is increasing but is still relatively low. Increasing numbers of young people abroad are experimenting with e-cigarettes but no trend data for the Netherlands are available to date. Young people who experiment with e-cigarettes are principally those young people who already smoke conventional cigarettes or have done so in the past; the same applies to adults. There are no indications that experimenting with e-cigarettes can lead to tobacco addiction. Although the vapour from e-cigarettes contains substances that are harmful to health, the health risks from the use of e-cigarettes are far smaller than those from smoking conventional cigarettes. Too few research data are available to be able to conclude that e-cigarettes are an effective aid to smoking cessation.

    Cigarette smoke increases the risk for respiratory and other diseases. Although smoking prevalence has declined over the years, millions of adults choose to continue to smoke. Modified risk tobacco products (MRTPs) are potentially valuable tools for adult smokers that are unwilling to quit their habit. Here, we investigated the biological impact of a candidate MRTP, the tobacco-heating system (THS) 2.2, compared to that of the 3R4F reference cigarette in normal primary human bronchial epithelial cells. Chemical characterization of the THS 2.2 aerosol showed reduced levels of harmful constituents compared to those of a combustible cigarette. Multiparametric indicators of cellular toxicity were measured via real-time cellular analysis and high-content screening. The study was complemented by a whole transcriptome analysis, followed by computational approaches to identify and quantify perturbed molecular pathways. Exposure of cells to 3R4F cigarette smoke resulted in a dose-dependent response in most toxicity end points. Moreover, we found a significant level of perturbation in multiple biological pathways, particularly in those related to cellular stress. By contrast, exposure to THS 2.2 resulted in an overall lower biological impact. At 3R4F doses, no toxic effects were observed. A toxic response was observed for THS 2.2 in some functional end points, but the responses occurred at doses between 3 and 15 times higher than those of 3R4F. The level of biological network perturbation was also significantly reduced following THS 2.2 aerosol exposure compared to that of 3R4F cigarette smoke. Taken together, the data suggest that THS 2.2 aerosol is less toxic than combustible cigarette smoke and thus may have the potential to reduce the risk for smoke-related diseases. PMID:26651182

    Caffeine-containing energy drinks have emerged as a public health concern due to their association with caffeine toxicity and alcohol use. Despite the fact that previous research has linked caffeine use in the form of coffee drinking to smoking, there is little research examining the association between energy drinks and smoking. The present study examines demographic and behavioral factors associated with energy drink use among a sample of rural Ohio Appalachian smokers. It was hypothesized that male gender, young age (21-30 years.) and alcohol use would be associated with energy drink use. A sample of adult smokers (n = 298) from Ohio Appalachian counties were interviewed regarding demographic and behavioral factors. Logistic regression analysis was used to assess the association between these factors and energy drink use. Seventy percent of Ohio Appalachian smokers studied had ever used an energy drink and 40 % had used an energy drink in the past month. Young age, male gender, and single marital status were associated with higher odds of ever having used an energy drink. Young age, and binge drinking were associated with higher odds of past 30-day use while abstinence from drinking was associated with lower odds of past 30-day use. Ohio Appalachian adult smokers had higher rates of energy drink use compared to previous estimates of ever or past month use found in other studies. The combined use of caffeine, nicotine, and alcohol warrants attention due to potential for health risk.

    Full Text Available Background and Aim: A strong causal relationship exists between cigarette smoking and development of oral squamous cell carcinoma, so oral screening using exfoliative cytology has been recommended to facilitate the early diagnosis of cellular alterations in oral mucosa and silver staining (AgNOR technique has been proven to be of value in the detection of incipient cellular alterations. The purpose of this study was to compare the argyrophilic nucleolar regions (AgNORs count of cells collected from normal mucosa of cigarette smokers with that obtained from non- smokers. Materials and Methods: In this cross-sectional study, cytologic smears of normal tongue, buccal mucosa and floor of the mouth from 19 smokers and 19 non- smokers were stained for AgNORs. The AgNORs count was established on 100 cells. The count value of groups were compared and analyzed using the Levens, Paired T, Student and Factorial tests. Using P<0.05 as the limit of significance. Results: The AgNORs were round and had a clustered distribution in both groups. The mean AgNORs count was statistically higher in cells of smokers than non- smokers (P<0.05. There was a significant difference between smears from the floor of the mouth and other anatomical sites in both groups. In this study, no correlation was found between AgNORs count and gender. Conclusion: Analysis of AgNORs suggests that there might be a correlation between the smoking habit and an increased rate of cellular proliferation in the oral mucosal cells.

    Full Text Available INTRODUCTION : Emphysema is defined by the American Thoracic Society thr ough pathological criteria as "A bnormal permanent enlargement of airspaces distal to terminal bronchioles , accompanied by destruction of their walls and without obvious fibrosis." In the present scenario there is no diagnostic tool to detect the susceptible smoker. Hence a noninvasive tool that can detect the pathologic al changes early will be of immense value to guide the physician to alter the risk factors in asymptomatic patients as emphysema has its roots decades before the onset of symptoms. Recently High Resolution Computed Tomography Scan (HRCT has established it self as a sensitive modality for the detection of early emphysema. MATERIALS AND METHODS : The study group consisted of 32 adult current smokers defined as those who have been smoking five or more cigarettes per day regularly for more than five years. The s tudy group was chosen from attendants/healthy volunteers who attended the outpatient department , Government Fever Hospital , Guntur between January 2014 to march 2015. RESULTS : All the 32 subjects included in the study were males. Overall normal spirometer was observed in all the subjects. 17 (53% out of 32 subjects had CT evidence of emphysema. 5 of these 17 subjects with emphysema showed evidence of air trapping on expiratory scans only with normal inspiratory HRCT scan. 15 subjects (47% had no evidence of emphysema on both inspiratory and expiratory HRCT scans. The incidence of emphysema increased with increasing age and pack years . CONCLUSIONS : The present study concludes that HRCT done in both inspiration and expiration is a good noninvasive modality to detect early emphysema in asymptomatic current smokers there by enabling the physician to implement preventive measures in susceptible subjects. The present study also emphasized the advantage of expiratory scan in detecting emphysema when inspiratory s can is normal. The HRCT of lung is also

    Full Text Available Abstract Background We have recently published some work on CEA levels in hookah (also called narghile, shisha elsewhere and cigarette smokers. Hookah smokers had higher levels of CEA than non-smokers although mean levels were low compared to cigarette smokers. However some of them were also users of other tobacco products (cigarettes, bidis, etc.. Objectives To find serum CEA levels in ever/exclusive hookah smokers, i.e. those who smoked only hookah (no cigarettes, bidis, etc., prepared between 1 and 4 times a day with a quantity of up to 120 g of a tobacco-molasses mixture each (i.e. the tobacco weight equivalent of up to 60 cigarettes of 1 g each and consumed in 1 to 8 sessions. Methods Enhanced chemiluminescent immunometric technique was applied to measure CEA levels in serum samples from 59 exclusive male smokers with age ranging from 20–80 years (mean = 58.8 ± 14.7 years and 8–65 years of smoking (mean = 37.7 ± 16.8. 36 non-smokers served as controls. Subjects were divided into 3 groups according to the number of preparations; the number of sessions and the total daily smoking time: Light (1; 1; ≤ 20 minutes; Medium (1–3; 1–3; >20 min to ≤ 2 hrs and Heavy smokers (2–4; 3–8; >2 hrs to ≤ 6 hrs. Because of the nature of distribution of CEA levels among our individuals, Wilcoxon's rank sum two-sample test was applied to compare the variables. Results The overall CEA levels in exclusive hookah smokers (mean: 3.58 ± 2.61 ng/ml; n = 59 were not significantly different (p ≤ 0.0937 from the levels in non-smokers (2.35 ± 0.71 ng/ml. Mean levels in light, medium and heavy smokers were: 1.06 ± 0.492 ng/ml (n = 5; 2.52 ± 1.15 ng/ml (n = 28 and 5.11 ± 3.08 ng/ml (n = 26 respectively. The levels in medium smokers and non-smokers were also not significantly different (p ≤ 0.9138. In heavy smokers, the CEA levels were significantly higher than in non-smokers (p ≤ 0.0001567. Conclusion Overall CEA levels in exclusive hookah

    Tobacco and tobacco smoke are very complex mixtures. In addition to various chemical and organic compounds they also contain natural radioactive elements (radionuclides). In this work, the natural radionuclide activity concentrations ((234)U, (238)U, (228)Th, (230)Th, (232)Th, (226)Ra, (210)Pb and (210)Po) of nine different cigarette samples available on the Slovenian market are reported. In addition to (210)Po, the transfer of thorium isotopes from a cigarette to a smoker's body and lungs have been determined for the first time. Cigarette smoke and exhaled air from smokers' lungs were collected from volunteer smokers (C-4 brand) to determinate what quantity of (210)Po and thorium isotopes is transferred from the tobacco to the smoker's lungs. Cigarette ash and smoked filters were also collected and analysed. Among the determined isotopes, (210)Pb and (210)Po showed the highest activity concentrations. During the smoking of one cigarette approximately 22% of (210)Po (and presumably its predecessor (210)Pb), 0.6% of (228)Th, 24% of (230)Th, and 31% of (232)Th are transferred from the cigarette and retained in the smoker's body. The estimated annual effective dose for smokers is 61 μSv/year from (210)Po; 9 μSv/year from (210)Pb; 6 μSv/year from (228)Th; 47 μSv/year from (230)Th, and 37 μSv/year from (232)Th. These results show the importance of thorium isotopes in contributing to the annual effective dose for smoking. PMID:26942842

  14. Smaller Cigarette Pack as a Commitment to Smoke Less? Insights from Behavioral Economics.

    Directory of Open Access Journals (Sweden)

    Joachim Marti

    Full Text Available Cigarettes are commonly sold in packs of 20 units and therefore little is known about the potential impact of pack size on consumption. Using insights from behavioral economics, we suggest that cigarette packs smaller than the standard size may help some smokers cut back and/or quit, consistent with their long-term goals. Results from an online hypothetical purchase experiment conducted in a sample of US smokers reveal that over a third of smokers are willing to pay a price premium to purchase in smaller quantities. Further, a desire to quit smoking and high self-control is associated with preference for a smaller pack. While we provide some preliminary evidence that smaller packs may be beneficial to certain types of smokers, further research should be conducted to assess whether the smaller pack size should be considered in the arsenal of tobacco control policies to help current smokers quit (JEL: I18; I12; D12.

    Full Text Available Objective. To determine the prevalence of the smoking habit among Mexican physicians as well as some of their attitudes and information on specific issues concerning smoking. Material and methods. In 1993, a survey was carried out among 3 568 physicians of the three major official health care institutions in Mexico City. A questionnaire designed for The Mexican National Survey of Addictions (ENA 1993 was used. Prevalence of cigarette smoking, age of onset, number of cigarettes per day; also information and attitudes concerning smoking were assessed. Results. The mean age was 37, 66% were males. Of the 3,488 (98% surveyed, 26.9% were smokers (62% daily, 20.6% were ex-smokers and 52.5% non-smokers. There were differences related to age and sex (p< 0.05. Of daily smokers, 36% smoked between 1 and 5 cigarettes. There was a significant trend among ex-smokers that linked the time they had ceased smoking with the fear to start smoking again. Physicians were well informed of the relationship between cigarette smoking and lung cancer. Over 80% considered tobacco an addictive drug but only 65% were in favor of banning smoking from their workplaces and over 10% were not aware that it is forbidden to smoke inside health care facilities. Conclusions. These results differ from other studies that find the prevalence of smoking among physicians lower than in the general population. Our study revealed a greater prevalence of the smoking habit among female physicians and the number of cigarettes smoked per day was greater than in the general population regardless of sex.

    AIM:To determine the levels of salivary immunoglobulin classes in Nigerian smokers and non-smokers with periodontitis.METHODS:Sixty-nine individuals were recruited into this study after obtaining informed consent.They were subdivided into three groups that consisted of 20(aged 46 ± 11 years) cigarette smokers with periodontitis(S+P);24(40 ± 12 years) smokers without periodontitis(S-P);and 25(53 ± 11 years) non-smokers with periodontitis(NS+P).An oral and maxillofacial surgeon used radiographs for periodontal probing for the diagnosis of periodontitis.The smokers included subjects who smoked at least six cigarettes per day and all the periodontitis patients were newly diagnosed.About 5 mL of unstimulated saliva was expectorated by each subject into plain sample bottles.Salivary immunoglobulin levels were estimated using enzyme linked immunosorbent assay.Student’s t test was used to deter-mine significant differences between the means.Values of P < 0.05 were regarded as significant.RESULTS:No significant differences were observed in the mean salivary levels of the immunoglobulin classes(IgG,IgA,IgM and IgE) when S+P was compared with S-P.Mean salivary levels of IgA(520.0 ± 155.1 ng/mL vs 670.0 ± 110 ng/mL,P = 0.000) and IgM(644.5 ± 160.0 ng/mL vs 791.4 ± 43.7 ng/mL,P = 0.000) were significantly lower in the S+P compared with NS+P group.Salivary IgA(570.4 ± 145.6 ng/mL vs 670.0 ± 110 ng/mL,P = 0.008) and IgM(703.1 ± 169.3 ng/mL vs 791.4 ± 43.7 ng/mL,P = 0.012) levels were significantly lower in the S-P compared with NS+P group.Only one(5%) periodontal patient had detectable levels of salivary IgE(0.20 IU/mL).Similarly,only one smoker(4.17%) had detectable levels of salivary IgE(0.04 IU/mL) and two non-smokers(9.52%) had detectable levels of IgE(0.24 IU/mL).CONCLUSION:Our study suggests that reduced salivary IgA and IgM levels in smokers with periodontitis could enhance increased susceptibility to periodontitis.

    The electronic cigarette (EC) is a device formed by three basic elements: battery, atomizer and cartridge. When assembled, it looks like a cigarette. The cartridge contains different substances: propylene glycol, glycerine and, sometimes, nicotine. When the user "vapes", the battery is activated, the atomizer is heated and the liquid is drawn in and vaporized. The smoker inhales the mist produced. Various substances have been detected in this mist: formaldehyde, acetaldehyde and acrolein and some heavy metals. Although these are found in lower concentrations than in cigarettes, they may still be harmful for the human body. Several surveys show that 3-10% of smokers regularly use e-cigarettes. A randomized study has shown that the efficacy of e-cigarettes for helping smokers to quit is similar to nicotine patches. Nevertheless, the study has relevant methodological limitations and reliable conclusions cannot be deduced. This report sets down the Position Statement of the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) on the efficacy and safety of e-cigarettes. This statement declares that e-cigarettes should be regulated as medicinal products.

    Circulating microRNAs (miRNAs) are receiving attention as potential biomarkers of various diseases, including cancers, chronic obstructive pulmonary disease, and cardiovascular disease. However, it is unknown whether the levels of circulating miRNAs in a healthy subject might vary with external factors in daily life. In this study, we investigated whether cigarette smoking, a habit that has spread throughout the world and is a risk factor for various diseases, affects plasma miRNA profiles. We determined the profiles of 11 smokers and 7 non-smokers by TaqMan MicroRNA array analysis. A larger number of miRNAs were detected in smokers than in non-smokers, and the plasma levels of two-thirds of the detected miRNAs (43 miRNAs) were significantly higher in smokers than in non-smokers. A principal component analysis of the plasma miRNA profiles clearly separated smokers and non-smokers. Twenty-four of the miRNAs were previously reported to be potential biomarkers of disease, suggesting the possibility that smoking status might interfere with the diagnosis of disease. Interestingly, we found that quitting smoking altered the plasma miRNA profiles to resemble those of non-smokers. These results suggested that the differences in the plasma miRNA profiles between smokers and non-smokers could be attributed to cigarette smoking. In addition, we found that an acute exposure of ex-smokers to cigarette smoke (smoking one cigarette) did not cause a dramatic change in the plasma miRNA profile. In conclusion, we found that repeated cigarette smoking substantially alters the plasma miRNA profile, interfering with the diagnosis of disease or signaling potential smoking-related diseases. - Highlights: • Plasma miRNA profiles were unambiguously different between smokers and non-smokers. • Smoking status might interfere with the diagnosis of disease using plasma miRNAs. • Changes of plasma miRNA profiles may be a signal of smoking-related diseases.

  19. The use and perception of electronic cigarettes and snus among the U.S. population.

    Full Text Available BACKGROUND: E-cigarettes have generated controversy in the tobacco control field similar to that of Swedish snus, which came to the U.S. market six years earlier. Some argue that e-cigarettes have great potential to help smokers quit regular cigarettes while others contend they should be banned for lack of safety and efficacy data. This study examined population data from the U.S. METHODS: A U.S. population survey with a national probability sample (N=10,041 was conducted (February 24 to March 8, 2012, before any major paid advertisement of e-cigarettes appeared on television. Survey respondents were asked if they had heard about e-cigarettes, where they had heard about them, whether they had used e-cigarettes or snus, how often they used them, and why they used them. Responses were weighted to represent the entire U.S. population. FINDINGS: A high proportion, 75.4%, reported having heard about e-cigarettes. Television ranked as the number one source of information, followed by "in-person conversation" and "Internet." About 8.1% had tried e-cigarettes, and 1.4% were current users. These rates were twice those of snus (4.3% and 0.8%, respectively. Among current smokers, 32.2% had tried e-cigarettes, and 6.3% were current users. Over 80% of current e-cigarette users were non-daily users. Women were significantly more likely to have tried e-cigarettes than men. Those who had tried e-cigarettes were more likely than those who tried snus to report their products being safer than regular cigarettes (49.9% vs. 10.8%. Almost half (49.5% of current smokers were susceptible to using e-cigarettes in the future. CONCLUSIONS: That e-cigarettes have surpassed snus in adoption rate, even before any promotion by major tobacco companies, suggests that the former have tapped into smokers' intuitive preference for potentially harm-reducing products, probably due to the product design. E-cigarette use is likely to increase in the next few years.

    The objective was to determine the prevalence of bronchial diverticula in smokers on thin-section CT and the relationship to clinical and other morphological features on CT. Thin-section CT images of 503 cigarette smokers were assessed for the profusion and location of diverticula in the major airways. The extent of the bronchial diverticula was recorded as follows: grade 0, none; grade 1, one to three diverticula; grade 2, more than three diverticula. The extent of emphysema, bronchial wall thickness, clinical features, and pulmonary function were compared in the sub-groups stratified according to the extent of bronchial diverticula. A total of 229/503 (45.5%) smokers had bronchial diverticula, with 168/503 (33.3%) and 61/503 (12.2%) having grade 1 and 2 bronchial diverticula respectively. Subjects with grade 2 bronchial diverticula were heavier smokers, reported a history of coughing more frequently, and showed more severe functional impairment, greater extent of emphysema and more severe bronchial wall thickening compared with subjects with grade 1 and those individuals without bronchial diverticula (P<0.05). Multivariate regression analysis revealed that only bronchial wall thickness predicted the extent of the bronchial diverticula (P<0.0001). Bronchial diverticula are a frequent finding in the major airways of smokers, and they are associated with other markers of smoking-related damage. (orig.)

    Full Text Available The most common form of smoking in the world is cigarette smoking, which is one of the leading causes of lung cancer, blood pressure, emphysema9, bronchitis, heart attack etc5… In the present study, Fourier-transform infrared spectroscopy was used for analysis of saliva sample for the detection of markers for smokers. The analysis included 7 individuals. The samples were classified as 2 samples from smokers of group 10-25, 2 samples from smokers of group 25-40, 1 sample from smokers of group 40-60 and 2 samples from smokers ofgroup 60 & above. Several interesting peaks have been identified as markers for smokers from saliva sample. Many peaks were significantly altered in absorption level of different age groups. The peaks at 754 cm-1, 1644 cm-1, 2136 cm-1, 3408 cm-1 were altered differently in different age groups as compared to non-smokers. Our study indicates that a stable marker was possible for active smokers by analysing the spectral graph obtained from the FTIR technique2. These parameters could be used for developing a spectral method of detection of active smokers along with predicting their duration of smoking by studying the effect of smoking in the different age groups.

    Full Text Available Abstract Background Little is known about users of electronic cigarettes, or their opinions, satisfaction or how and why they use such products. Methods An internet survey of 81 ever-users of ecigarettes in 2009. Participants answered open-ended questions on use of, and opinions about, ecigarettes. Results Respondents (73 current and 8 former users lived in France, Canada, Belgium or Switzerland. Most respondents (77% were men; 63% were former smokers and 37% were current smokers. They had used e-cigarettes for 100 days (median and drew 175 puffs per day (median. Participants used the ecigarette either to quit smoking (53 comments, to reduce their cigarette consumption (14 comments, in order not to disturb other people with smoke (20 comments, or in smoke-free places (21 comments. Positive effects reported with ecigarettes included their usefulness to quit smoking, and the benefits of abstinence from smoking (less coughing, improved breathing, better physical fitness. Respondents also enjoyed the flavour of ecigarettes and the sensation of inhalation. Side effects included dryness of the mouth and throat. Respondents complained about the frequent technical failures of ecigarettes and had some concerns about the possible toxicity of the devices and about their future legal status. Conclusions Ecigarettes were used mainly to quit smoking, and may be helpful for this purpose, but several respondents were concerned about potential toxicity. There are very few published studies on ecigarettes and research is urgently required, particularly on the efficacy and toxicity of these devices.

    Experimental studies on the effects of graphic fear appeals on cigarette packages typically expose smokers in a single session to a fear appeal, although in practice the exposure is always repeated. The present study applied an improved study design with repeated exposure to fear appeals on cigarette packages. In this field-experiment, 118 smokers were assigned to 1 of 2 conditions with either graphic fear appeals or textual warnings on their cigarette packages. During 3 weeks, fear and disgust were assessed 6 times. The intention to quit smoking after 3 weeks and quitting activity during the 3 weeks were the dependent measures. The effects of 3 pretest individual difference moderators were tested: disengagement beliefs, number of cigarettes smoked a day, and readiness to quit. Three weeks of exposure to the graphic fear appeals led to a stronger intention to quit, but only when smokers scored low on disengagement beliefs, or were heavier smokers. In addition, smokers low in disengagement more often reported to have cut down on smoking in the graphic condition. There were no indications of habituation of fear and disgust over the 3 weeks. The effects of graphic fear appeals depended on smokers' characteristics: The moderators may explain the mixed findings in the literature. The lack of habituation may be caused by the renewal of the graphics every few days. The used field-experimental design with natural repeated exposure to graphics is promising. PMID:25621418

  6. Impact of cigarette taxation policy on excise revenues and cigarette consumption in Uzbekistan

    2013-05-01

    Full Text Available BACKGROUND: In 2012, Uzbekistan ratified the Framework Convention on Tobacco Control, which states that price and tax measures are an effective means of reducing tobacco consumption. We aimed to explore the effect of taxation policies on revenues and cigarette consumption. METHODS: Data on tax rates, revenues, cigarette sales were taken from national reports. To forecast potential revenues, a scenario analysis was performed. RESULTS: In 1991-2004, ad valorem excise system was in place in Uzbekistan, which was later replaced by the specific excise system. In 1997-2011, the nominal average excise has increased by a factor of twenty, but in real terms, after a sharp increase in 1999, average excise declined annually and increased only in 2010-2011. Annual cigarette sales per capita of adult population in 1999-2007 constituted 17-25 cigarette packs, while in 2008-2011 it increased to 30-37 packs. Four scenarios of excise tax increases in 2012 were developed: one actual scenario based on the rates effective in Uzbekistan in 2012, and three hypothetical ones anticipating excise rates increase by 1.5, 2 and 3-fold. With actual excise increase in 2012, the inflation-adjusted budget revenues would grow by 5%, and with three hypothetical - by 17%, 35% and 66% respectively, despite the decline of tax-paid cigarette sales. CONCLUSION: Stabilization or reduction in cigarette excises in Uzbekistan in 2002-2008 led to a decline in real excise revenues and the growth of cigarette sales. In 1999 and 2010-2011, excises were significantly increased and the real revenues have risen, despite the decline in cigarette sales. As cigarette prices are low, the illegal outflow of cigarettes from Uzbekistan apparently exceeds the illegal inflow. A significant increase in cigarette excise (1.5-3 fold can both increase budget revenues and reduce cigarette consumption, with greater increase yielding more benefits.

This study was undertaken to evaluate the lipid profile, plasma fibrinogen and platelet count in male smokers, compared with healthy non smokers in rural area of south India, Out of 100 male healthy volunteers, 50 members were healthy smokers and 50 healthy non smokers, subjects were divided in both groups in age around 30 to 45yrs, with no past history of diabetes mellitus, hypertension, hepatic disorders and were neither on anti hypertensive, lipid lowering drugs were included in the study. Lipid profile, plasma fibrinogen and platelet count were analyzed by standard methods. Our results showed mean platelet count for smokers is 2, 86,345per mm3 and for non-smokers 2, 04,484.6per mm3. The mean plasma fibrinogen concentration for smokers is 3.48gm/dl and for non smokers is 3.12gm/dl. The platelet count and plasma fibrinogen concentration shows a higher value for smokers when compared to non- smokers. This is statistically significant. The mean total cholesterol level for smokers (186±30.10 mg/dl and non smokers (166.3±24.26 mg/dl and the mean triglyceride level for smokers (175±59.43 mg/dl and non smokers (132.09±+33.80 mg/dl are also statistically significant. The mean HDL level for smokers (40.4±4.13 mg/dl and for non smokers (44.68±4.13 mg/dl, the mean LDL level for smokers (105.8±28.16 mg/dl and non smokers (89.68±16.50 mg/dl and the mean VLDL level for smokers (28.4± 8.16 mg/dl and non smokers (14.3.±3.2 mg/dl indicate that the Lipid profile also is statistically significant between the two groups. We concluded that there is an elevated lipid profile; plasma fibrinogen and platelet count in smokers when compared to non smokers, which shows that smokers have high risk of prevalence of cardiovascular and vessel wall

  9. Mu Opioid Receptor Binding Correlates with Nicotine Dependence and Reward in Smokers.

    Directory of Open Access Journals (Sweden)

    Hiroto Kuwabara

    Full Text Available The rewarding effects of nicotine are associated with activation of nicotine receptors. However, there is increasing evidence that the endogenous opioid system is involved in nicotine's rewarding effects. We employed PET imaging with [11C]carfentanil to test the hypotheses that acute cigarette smoking increases release of endogenous opioids in the human brain and that smokers have an upregulation of mu opioid receptors (MORs when compared to nonsmokers. We found no significant changes in binding potential (BPND of [11C]carfentanil between the placebo and the active cigarette sessions, nor did we observe differences in MOR binding between smokers and nonsmokers. Interestingly, we showed that in smokers MOR availability in bilateral superior temporal cortices during the placebo condition was negatively correlated with scores on the Fagerström Test for Nicotine Dependence (FTND. Also in smokers, smoking-induced decreases in [11C]carfentanil binding in frontal cortical regions were associated with self-reports of cigarette liking and wanting. Although we did not show differences between smokers and nonsmokers, the negative correlation with FTND corroborates the role of MORs in superior temporal cortices in nicotine addiction and provides preliminary evidence of a role of endogenous opioid signaling in frontal cortex in nicotine reward.

  10. The impact of smoking in adolescence on early adult anxiety symptoms and the relationship between infant vulnerability factors for anxiety and early adult anxiety symptoms: the TOPP Study.

    Full Text Available Cigarette smoking is increased in people with trait anxiety and anxiety disorders, however no longitudinal data exist illuminating whether smoking in adolescence can influence the developmental trajectory of anxiety symptoms from early vulnerability in infancy to adult anxiety expression. Using The Tracing Opportunities and Problems in Childhood and Adolescence (TOPP Study, a community-based cohort of children and adolescents from Norway who were observed from the age of 18 months to age 18-19 years, we explored the relationship between adolescent smoking, early vulnerability for anxiety in infancy (e.g. shyness, internalizing behaviors, emotional temperaments and reported early adult anxiety. Structural equation modeling demonstrated that adolescent active smoking was positively associated with increased early adulthood anxiety (β = 0.17, p<0.05, after controlling for maternal education (proxy for socioeconomic status. Adolescent anxiety did not predict early adult smoking. Adolescent active smoking was a significant effect modifier in the relationship between some infant vulnerability factors and later anxiety; smoking during adolescence moderated the relationship between infant internalizing behaviors (total sample: active smokers: β = 0.85, p<0.01, non-active smokers: ns and highly emotional temperament (total sample: active smokers: β = 0.55, p<0.01,non-active smokers: ns, but not shyness, and anxiety in early adulthood. The results support a model where smoking acts as an exogenous risk factor in the development of anxiety, and smoking may alter the developmental trajectory of anxiety from infant vulnerability to early adult anxiety symptom expression. Although alternative non-mutually exclusive models may explain these findings, the results suggest that adolescent smoking may be a risk factor for adult anxiety, potentially by influencing anxiety developmental trajectories.

    The aerosol generated when a cigarette is smoked is a significant indoor contaminant. Both smokers and non-smokers can be exposed to this class of pollutants. Nevertheless, they are not exposed to the same kind of smoke. The active smoker breathes in the mainstream smoke (MSS) during a puff, whereas the passive smoker inhales not only the smoke generated by the lit cigarette between two puffs (SSS) but also the smoke exhaled by active smokers (EXS). The aerosol fraction of EXS has until now been poorly documented; its composition is expected to be different from MSS. This study aims to investigate the complex composition of aerosol from EXS to better understand the difference in exposure between active and passive smokers. To address this, the in-situ laser desorption ionisation Fourier transform ion cyclotron mass spectrometry (LDI-FTICRMS) was used to characterise the aerosol composition of EXS from two different smokers. Results clearly indicated many similarities between EXS samples but also significant differences with MSS and SSS aerosol. The comparison of MSS and EXS aerosol allowed the chemicals retained by the active smoker's lungs to be identified, whereas the convolution of the EXS and SSS aerosol compositions were considered relevant to the exposition of a passive smoker. As a consequence, active smokers are thought to be mainly exposed to polar and poorly unsaturated oxygenated and nitrogenated organics, compared with poorly oxygenated but highly unsaturated compounds in passive smokers.

    Full Text Available Introduction. Smoking and tuberculosis are among the most important problems of public health. Smoking and tuberculosis are responsible for 5 million and 2 million deaths per year, respectively, whereas smoking is responsible for half a million deaths in patients with tuberculosis. Discussion and Review of Literature. Nicotine is a significant suppressor of function of macrophages, dendritic cells and T-cells, which explains the immunosuppressive features of smoking that help develop the infection. Tobacco smoke contains many substances with immunomodulatory effects, including nicotine, carbon monoxide, acrolein, peroxynitrite and many others. The dominant immune and pathophysiological mechanism is the reduction of synthesis of tumor necrosis factor in lung macrophages, leading to increased susceptibility of persons who are exposed to tobacco smoke for developing active tuberculosis after infection and increased susceptibility to the development of other infections, such as infections of Gram-negative bacteria. Based on epidemiological studies and studies on this problem in the past 50 years, the World Health Organization has published the finding that smoking increases the risk of infection with M. tuberculosis, increases the risk of progression of infection to active disease and the risk of death. The prevalence of tuberculosis is higher in smokers and former smokers than in nonsmokers. The risk of tuberculosis depends on the number of cigarettes smoked and length of period the person has been a smoker. Passive smoking accelerates the development of active tuberculosis. in children who live with persons suffering from active tuberculosis, Conclusion. Given the multiple consequences of the association between smoking and tuberculosis, prevention of smoking may be an important measure in the control of tuberculosis.

  13. Increased levels of metallothionein in placenta of smokers

    International Nuclear Information System (INIS)

    Experiments were designed to evaluate and compare metallothionein (MT), zinc and cadmium levels in human placentas of smoking and non-smoking women. Smoking was assessed by self-reported cigarette consumption and urine cotinine levels before delivery. Smoking pregnant women with urine cotinine levels higher than 130 ng/ml were included in the smoking group. Determination of placental MT was performed by western blot analysis after tissue homogenization and saturation with cadmium chloride (1000 ppm). Metallothionein was analyzed with a monoclonal antibody raised against MT-1 and MT-2 and with a second anti mouse antibody conjugated to alkaline phosphatase. Zinc and cadmium were determined by neutron activation analysis and atomic absorption spectrometry respectively. Smokers showed higher placental MT and cadmium levels, together with decreased newborn birth weights, as compared to non-smokers. The semi-quantitative analysis of western blots by band densitometry indicated that darker bands corresponded to MT present in smokers' samples. This study confirms that cigarette smoking increases cadmium accumulation in placental tissue and suggests that this element has a stimulatory effect on placental MT production

    Full Text Available BACKGROUND: Smoking is the preventable risk factor for many non - communicable diseases like COPD, atherosclerotic diseases, stroke and many malignancies. Many smokers smoke their 1 st cigarette at early age due to various social factors. Ma ny of the smokers doesn’t know the harmful effects of the smoking on individual systems. METHODS : Prospective study conducted on 102 smokers attending to outpatient department of the Government fever hospital, Guntur. They were surveyed about their smoking preferences. After taking the preliminary details they are enquired about the level of awareness of harmful effects of smoking. RESULT : More than half the members (n=56 , 54.90% smoke in their houses. They don’t know about effect of second hand smoke on th e health of the members. Only few members know the complication of the smoking like Skin diseases (17 , 16.66%, Cerebrovascular accidents (26 , 25.49% and endocrine complications including diabetes (n=2, 1.8%. Most of subjects know risk of Carcinomas (92,90 .19%, Cardiovascular diseases (34,33.33% and Respiratory diseases (85,83.33%. People continue smoking inspite of awareness of complications of smoking due their addiction. CONCLUSIONS : Newer policies should raise towards educating the people about the exact impact of smoking on health. Policies should target the younger people that should stop smoking their 1 st cigarette or beedi

    The rate of clearance from the lung of the hydrophilic tracer molecule /sup 99m/Tc DTPA was used to investigate the short-term effects on lung epithelial function when smokers switched to cigarettes with lower yields of tobacco smoke constituents. Two separate studies were performed. In the first study, subjects smoked conventional mid- and low-tar cigarettes. The second study used two specially manufactured cigarettes with similar tar and nicotine yields, but differing carbon monoxide yields. Neither study demonstrated any significant improvement in /sup 99m/Tc DTPA clearance. The yields of carbon monoxide determined under standard machine smoking conditions implied that there would be a 44 percent reduction in exposure to carbon monoxide when subjects switched from smoking conventional mid-tar to low-tar cigarettes. However, measurements of carboxyhemoglobin showed that the smokers compensated for the lower yields and their exposure was reduced by only 11 percent. Similarly, in the second study, the subjects reduced their exposure by 7 percent instead of the expected 44 percent. Urine nicotine/cotinine excretion measurements in this study indicated that there was no complimentary increase in nicotine absorption suggesting the possibility that subjects may be able to regulate their intake of individual components of the cigarette smoke. Thus, the unexpected result from this study was the finding that cigarette smokers could, in some way, regulate their intake of smoke from cigarettes of different composition so as to maintain a constant exposure of smoke constituents.

  16. Cigarette purchasing behaviour in Thailand and Malaysia: comparative analysis of a semi-monopolistic and a free-market structure.

    A wide range of cigarette prices can undermine the impact of tobacco tax policy when smokers switch to cheaper cigarettes instead of quitting. In order to better understand this behaviour, we study socio-economic determinants of price/brand choices in two different markets: a semi-monopolistic market in Thailand and a competitive market in Malaysia. The hypothesis that the factors affecting the price/brand choice are different in these two markets is analysed by employing a 2005 survey among smokers. This survey provides a unique perspective on market characteristics usually described only in business reports by the tobacco industry. We found that smokers in Thailand have fewer opportunities to trade down to save money on cigarettes, but pay lower prices than smokers in Malaysia, despite Thailand's higher tax rate. The Malaysian market, on the other hand, offers many possibilities to shop around for cheaper cigarettes. Higher income and education increase the price paid per cigarette in both countries, but the impact of these factors is larger in Malaysia. This has implications for sensitivity to cigarette prices. Using tax policy alone should be a more effective tobacco control measure in Thailand as compared to Malaysia. The effectiveness of a tax increase in Malaysia can be improved by adding programmes focusing on smoking cessation among low-income/low-educated smokers.

  17. Reasons for Starting and Stopping Electronic Cigarette Use

    Full Text Available The aim of our study was to explore reasons for starting and then stopping electronic cigarette (e-cigarette use. Among a national sample of 3878 U.S. adults who reported ever trying e-cigarettes, the most common reasons for trying were curiosity (53%; because a friend or family member used, gave, or offered e-cigarettes (34%; and quitting or reducing smoking (30%. Nearly two-thirds (65% of people who started using e-cigarettes later stopped using them. Discontinuation was more common among those whose main reason for trying was not goal-oriented (e.g., curiosity than goal-oriented (e.g., quitting smoking (81% vs. 45%, p < 0.001. The most common reasons for stopping e-cigarette use were that respondents were just experimenting (49%, using e-cigarettes did not feel like smoking cigarettes (15%, and users did not like the taste (14%. Our results suggest there are two categories of e-cigarette users: those who try for goal-oriented reasons and typically continue using and those who try for non-goal-oriented reasons and then typically stop using. Research should distinguish e-cigarette experimenters from motivated users whose decisions to discontinue relate to the utility or experience of use. Depending on whether e-cigarettes prove to be effective smoking cessation tools or whether they deter cessation, public health programs may need distinct strategies to reach and influence different types of users.

    Cigarette smoking is a chronic relapsing brain disorder, and remains a premier cause of morbidity and mortality. Functional neuroimaging has been used to assess differences in the mean strength of brain activity in smokers' brains, however less is known about the temporal dynamics within smokers' brains. Temporal dynamics is a key feature of a dynamic system such as the brain, and may carry information critical to understanding the brain mechanisms underlying cigarette smoking. We measured the temporal dynamics of brain activity using brain entropy (BEN) mapping and compared BEN between chronic non-deprived smokers and non-smoking controls. Because of the known sex differences in neural and behavioral smoking characteristics, comparisons were also made between males and females. Associations between BEN and smoking related clinical measures were assessed in smokers. Our data showed globally higher BEN in chronic smokers compared to controls. The escalated BEN was associated with more years of smoking in the right limbic area and frontal region. Female nonsmokers showed higher BEN than male nonsmokers in prefrontal cortex, insula, and precuneus, but the BEN sex difference in smokers was less pronounced. These findings suggest that BEN mapping may provide a useful tool for probing brain mechanisms related to smoking. PMID:27377552

  19. Abnormal ventilation scans in middle-aged smokers. Comparison with tests of overall lung function

    International Nuclear Information System (INIS)

    The uniformity of regional ventilation during tidal breathing has been assessed using continuous inhalation of krypton-81m in 43 male, lifelong nonsmokers and 46 male, current cigarette smokers (mean daily consumption 24.1 cigarettes/day) between 44 and 61 yr of age and with mild or no respiratory symptoms. All subjects had normal chest radiographs. The results of the ventilation scans were compared with tests of overall lung function (spirometry, maximal expiratory flow-volume curves, and single-breath N2 test). Diffuse abnormalities of the ventilation scan were found in 19 (41%) of the 46 smokers but in none of the nonsmokers. Focal abnormalities were found in 7 smokers and 3 nonsmokers. Smokers showed the expected abnormalities in overall lung function (reduced FEV1 and VC, increased single-breath N2 slope, and closing volume), but in individual smokers there was only a weak relation between the severity of abnormality of overall lung function and an abnormal ventilation scan. Abnormal scans could be found when overall lung function was normal and were not invariably found when significant abnormalities in FEV1/VC or N2 slope were present. There was no relation between the presence of chronic expectoration and an abnormal scan. The prognostic significance of an abnormal ventilation scan in such smokers remains to be established

    Despite the recent popularity of e-cigarettes, to date only limited data is available on their safety for both users and secondhand smokers. The present study reports a comprehensive inner and outer exposure assessment of e-cigarette emissions in terms of particulate matter (PM), particle number concentrations (PNC), volatile organic compounds (VOC), polycyclic aromatic hydrocarbons (PAH), carbonyls, and metals. In six vaping sessions nine volunteers consumed e-cigarettes with and without nicotine in a thoroughly ventilated room for two hours. We analyzed the levels of e-cigarette pollutants in indoor air and monitored effects on FeNO release and urinary metabolite profile of the subjects. For comparison, the components of the e-cigarette solutions (liquids) were additionally analyzed. During the vaping sessions substantial amounts of 1,2-propanediol, glycerine and nicotine were found in the gas-phase, as well as high concentrations of PM2.5 (mean 197 μg/m(3)). The concentration of putative carcinogenic PAH in indoor air increased by 20% to 147 ng/m(3), and aluminum showed a 2.4-fold increase. PNC ranged from 48,620 to 88,386 particles/cm(3) (median), with peaks at diameters 24-36 nm. FeNO increased in 7 of 9 individuals. The nicotine content of the liquids varied and was 1.2-fold higher than claimed by the manufacturer. Our data confirm that e-cigarettes are not emission-free and their pollutants could be of health concern for users and secondhand smokers. In particular, ultrafine particles formed from supersaturated 1,2-propanediol vapor can be deposited in the lung, and aerosolized nicotine seems capable of increasing the release of the inflammatory signaling molecule NO upon inhalation. In view of consumer safety, e-cigarettes and nicotine liquids should be officially regulated and labeled with appropriate warnings of potential health effects, particularly of toxicity risk in children.

    We estimated the mortality from various diseases caused by cigarette smoking using two methods and compared the results. In one method, the "Prevent" model is used to simulate the effect on mortality of the prevalence of cigarette smoking derived retrospectively. The other method, suggested by R...... are small and appear to be explicable. The Prevent model can be used for more general scenarios of effective health promotion, but it requires more data than the Peto et al method, which can be used only to estimate mortality related to smoking........ Peto et al (Lancet 1992;339:1268-1278), requires data on mortality from lung cancer among people who have never smoked and among smokers, but it does not require data on the prevalence of smoking. In the Prevent model, 33% of deaths among men and 23% of those among women in 1993 from lung cancer...

  2. Children's perceptions of advertisements for cigarettes.

    1985-01-01

    Groups of children aged between 6 and 16 years discussed a series of advertisements, including those for cigarettes. Clear patterns emerged in their recognition of cigarette brand imagery. For example, in response to an advertisement for holidays which also presents the brand imagery of John Player Special cigarettes, 22% of primary school children and 91% of secondary school children said it advertises cigarettes. There were consistent trends in responses to the symbolism portrayed. Younger children were very much tied to what was specifically shown in the advertisements; older ones tended to perceive more complex imagery. For example, whereas 10-year-olds said people who like the advertisement for Kim cigarettes (which has symbols for drinking) would smoke and drink, some 12-year-olds and most 14- and 16-year-olds saw Kim as feminine, sociable, trendy and sporty. It seems that some 12-year-olds and most 14- and 16-year-olds perceive cigarette advertisements much in the way that young adults do; therefore advertising campaigns targeted at older teenagers and young adults are likely to present qualities which younger teenagers find attractive.

    In Italy, every year about 72 billion of cigarette butts are thrown away in the environment. Cigarette butts represent 50% of the wastes of urban areas (parks, roads) in the world, and 40% of Mediterranean Sea wastes. In particular, total polluting load is constituted of 1,872 Bq millions of Polonium-210, assuming 75 mBq per cigarette butt, and 1,800 tons of volatile organic compounds. As a matter of fact, according to several surveys, cigarette butts are considered by smokers and non-smokers as a common and acceptable waste in the environment. In 2008, European Union issued a Directive on wastes considering the «extended producer responsibility» (i.e., every industry is liable for costs of collection, transport and disposal of its own products). In October 2012, the Italian Parliament proposed a bill that classifies cigarette butts as special wastes in the frame of this responsibility. It could be interesting in the future to follow the legislative process of that bill in the Italian Parliament in order to show how strong it will be supported.

    The adverse effects of smoking have fostered a natural market for smoking cessation and smoking reduction products. Smokers attempting to quit or reduce consumption have tried everything: "low" or "light" cigarettes; nicotine-infused chewing gum, lozenges, and lollipops; dermal patches; and even hypnosis. The latest craze in the quest to find a safer source of nicotine is the electronic cigarette. Electronic cigarettes (e-cigarettes) have swept the market, reaching a rapidly expanding international consumer base. Boasting nicotine delivery and the tactile feel of a traditional cigarette without the dozens of other chemical constituents that contribute to carcinogenicity, e-cigarettes are often portrayed as less risky, as a smoking reduction or even a complete smoking cessation product, and perhaps most troubling for its appeal to youth, as a flavorful, trendy, and convenient accessory. The sensationalism associated with e-cigarettes has spurred outcry from health and medical professional groups, as well as the Food and Drug Administration (FDA), because of the unknown effects on public health. Inhabiting a realm of products deemed "tobacco products" under recent 2009 legislation, e-cigarettes pose new challenges to FDA regulation because of their novel method of nicotine delivery, various mechanical and electrical parts, and nearly nonexistent safety data. Consumer use, marketing and promotional claims, and technological characteristics of e-cigarettes have also raised decades old questions of when the FDA can assert authority over products as drugs or medical devices. Recent case law restricting FDA enforcement efforts against e-cigarettes further confounds the distinction among drugs and medical devices, emerging e-cigarette products, and traditional tobacco products such as cigarettes, cigars, and smokeless tobacco.

    Full Text Available Craving is a core feature of tobacco use disorder as well as a significant predictor of smoking relapse. Studies have shown that appetitive smoking-related stimuli (e.g. someone smoking trigger significant cravings in smokers which impedes their self-control capacities and promotes drug seeking behavior. In this review, we begin by an overview of functional magnetic resonance imaging (fMRI studies investigating the neural correlates of smokers to appetitive smoking cues. The literature reveals a complex and vastly distributed neuronal network underlying smokers’ craving response that recruits regions involved in self-referential processing, panning/regulatory processes, emotional responding, attentional biases, and automatic conducts. We then selectively review important factors contributing to the heterogeneity of results that significantly limit the implications of these findings, namely between- (abstinence, smoking expectancies and self-regulation and within-studies factors (severity of smoking dependence, sex-differences, motivation to quit and genetic factors. Remarkably, we found that little to no attention has been devoted to examine the influence of personality traits on the neural correlates of cigarette cravings in fMRI studies. Impulsivity has been linked with craving and relapse in substance and tobacco use, which prompted our research team to examine the influence of impulsivity on cigarette cravings in an fMRI study. We found that the influence of impulsivity on cigarette cravings was mediated by fronto-cingular mechanisms. Given the high prevalence of cigarette smoking in several psychiatric disorders that are characterized by significant levels of impulsivity, we conclude by identifying psychiatric patients as a target population whose tobacco smoking habits deserve further behavioral and neuro-imaging investigation.

    Full Text Available We used longitudinal data to investigate the relationship between computer use in internet cafés and smoking/drinking behavior among Chinese adolescents and young adults. Data are from two waves of the China Health and Nutrition Survey (2004 and 2006. Fixed effects models were used to examine if changes in internet café use were associated with changes in cigarette smoking and drinking of alcohol. Male café users spent on average 17.3 hours in front of the computer/week. This was associated with an increase in the probability of being a current smoker by 13.3% and with smoking 1.7 more cigarettes. Female café users spent on average 11 hours on the computer/week. This was associated with an increase in the probability of drinking wine and/or liquor by 14.74% and was not associated with smoking. Internet cafés are an important venue by which adolescent and young adults in China are exposed to smoking and drinking. Multi-component interventions are needed ranging from policies regulating cigarette and alcohol availability in these venues to anti-tobacco campaigns aimed at the general population but also at individuals who frequent these establishments.

    Full Text Available Background: The deterioration in lung function associated with Chronic Obstructive Pulmonary Disease (COPD is directly related to duration of smoking and the number of cigarettes smoked. Over 85% of lung cancers are attributed to smoking. The problem is, whether the length of smoking consumption period has more impact to COPD and lung cancer than the bigger number of cigarettes smoked per day?Examinees and methods: The sample has constituted of two groups of examinees, smokers, both gender, age 25-64 years old. The first group consisted of 240 examinees divided in 8 subgroups according to a number of years they have been smoking. The second group consisted of 180 examinees, which was divided in 6 subgroups, according to average number of cigarettes smoked daily during the smoking consumption period.Results: The prevalence of smoking was higher in men (65.7% vs. 62% than in women (34.3% vs. 38%. Smoking duration in the group of smokers according to the length of smoking consumption period was 20.34±10.63 y and in the group of smokers according to a number of cigarettes smoked daily 13.55±8.20y. COPD were registered as the most frequent lung disease, in the group of smokers according to a number of cigarettes smoked per day 52.2% and in the group according to the length of smoking consumption period 39.1%, and the middle values of FEV1 (82.77% vs. 97.64%, and FEV1/FVC (86.02% vs. 97.73% were lower in the group of smokers according to a number of cigarettes smoked.Conclusion: Chronic respiratory symptoms, impairment of lung function and diagnosis of COPD depended more on the length of smoking duration than a number of cigarettes smoked.

    Full Text Available Abstract Background Addiction to nicotine gum has never been described in never smokers or in never users of tobacco. Methods Internet questionnaire in 2004–2006 in a self-selected sample of 434 daily users of nicotine gum. To assess dependence on nicotine gum, we used modified versions of the Nicotine Dependence Syndrome Scale (NDSS, the Fagerström Test for Nicotine Dependence and the Cigarette Dependence Scale. Results Five never smokers used the nicotine gum daily. They had been using the nicotine gum for longer than the 429 ever smokers (median = 6 years vs 0.8 years, p = 0.004, and they had higher NDSS-gum Tolerance scores (median = 0.73 vs = -1.0, p = 0.03, a difference of 1.5 standard deviation units. Two never smokers had never used smokeless tobacco, both answered "extremely true" to: "I use nicotine gums because I am addicted to them", both "fully agreed" with: "after a few hours without chewing a nicotine gum, I feel an irresistible urge to chew one" and: "I am a prisoner of nicotine gum". Conclusion This is to our knowledge the first report of addiction to nicotine gum in never users of tobacco. However, this phenomenon is rare, and although the long-term effect of nicotine gum is unknown, this product is significantly less harmful than tobacco.

  13. Use of spirometry in detecting airway obstruction in asymptomatic smokers

    International Nuclear Information System (INIS)

    Objectives: To detect spirometric abnormalities in asymptomatic smokers in relation to duration of smoking. Study Design: Cross sectional study. Place and Duration of Study: The study was carried out at PNS Shifa from Oct 2006 to June 2007. Subjects and Methods: Hundred individuals were included in this study who fulfilled the required criteria. Spirometry was done after briefing the patient about the procedure. Smokers were divided into two groups. Group I (5 to 9 pack years) and group II (= 10 pack years). All relevant information were recorded on Performa (Annex-A). The data was analyzed through SPSS-10, in terms of Mean +- SD (Standard Deviation) for numeric response variables and independent sample T test was applied to compare significance of proportion for numeric response variables at p < 0.05. Categorical variables were compared by applying Chi-square test at p < 0.05 level of significance. Results: Significant statistical difference was found between the mean age in the two groups with p-value of 0.011. This may be due to the longer duration of smoking history in Group II. Strong association was found between number of cigarette smoked and the pattern of airway obstruction as significant statistical difference of airway obstruction and early airflow limitation was found between the two groups of smokers at p value of 0.004. Conclusion: There is strong association between duration of smoking and development of airway obstruction even before the smoker become symptomatic. (author)

    Background Chronic obstructive pulmonary disease (COPD) is thought to be an inflammatory immune response disease. In most cases, the disease is caused by cigarette smoke, but it has been demonstrated that only 10% to 20% of smokers will definitely suffer from COPD. Dendritic cells (DCs) are considered to be the promoter of immune responses.However, the underlying mechanisms involved are still unrevealed. In this study, we aimed to investigate the quantitative differentiation of pulmonary DC in smokers with or without COPD to explore the possible role of DCs in smokers suffering COPD.Methods Peripheral lung specimens from non-smokers without airflow obstruction (control group, n=7), smokers without airflow obstruction (smoker group, n=7) and patients with COPD (COPD group, n=7) were investigated to detect the quantity of S-100 and CD1a positive cells by immunohistochemical or immunofluorescent assay.Results In smokers with COPD, the number of S-100+ DCs was higher than in the controls and smokers without COPD (P 0.05). An inverse correlation was found between the number of DCs and forced expiratory volume in the first second (FEV1)% pred (r=-0.75, P <0.05), which was also found between the number of DCs and FEV1/forced vital capacity (FVC) (r=-0.72, P <0.05). The mean number of CD1a+ DCs, increased from non-smokers to non-COPD smokers to COPD patients, with significant differences between each group (P <0.01).Conclusions The quantity of DCs significantly increased in smokers with COPD compared with non-smokers or smokers without COPD. The results suggest that DCs may play an important role in the pathogenesis of smoking-induced COPD, and the upregulation of DCs may be a potential maker to identify the smokers who have more liability to suffer from COPD.

    Full Text Available Abstract Background Tobacco use is responsible for 5.4 million deaths every year worldwide and is a leading cause of preventable death. The burden of these deaths is rapidly shifting to low and middle-income countries, such as Brazil. Brazil has prohibited most forms of tobacco advertising; however, the cigarette pack remains a primary source of marketing. The current study examined how tobacco packaging influences brand appeal and perceptions of health risk among young women in Brazil. Methods A between-subjects experiment was conducted in which 640 Brazilian women aged 16–26 participated in an online survey. Participants were randomized to view 10 cigarette packages according to one of three experimental conditions: standard branded packages, the same packs without brand imagery (“plain packaging”, or the same packs without brand imagery or descriptors (e.g., flavors. Participants rated packages on perceived appeal, taste, health risk, smoothness, and smoker attributes. Finally, participants were shown a range of branded and plain packs from which they could select one as a free gift, which constituted a behavioral measure of appeal. Results Branded packs were rated as significantly more appealing, better tasting, and smoother on the throat than plain packs. Branded packs were also associated with a greater number of positive smoker attributes including style and sophistication, and were perceived as more likely to be smoked by females than the plain packs. Removing descriptors from the plain packs further decreased the ratings of appeal, taste and smoothness, and also reduced associations with positive attributes. In the pack offer, participants were three times more likely to select branded packs than plain packs. Conclusions Plain packaging and removal of descriptors may reduce the appeal of smoking for youth and young adults, and consequently reduce smoking susceptibility. Overall, the findings provide support for plain packaging

    Tran, Thuy-Ngan N.; Le, Cong-Hao; Chau, Van-Tao

    Smoking cigarettes contributes significantly to the increase of radiation in human body because 210Po and 210Pb exist relatively high in tobacco leaves. Therefore, these two radioisotopes in eighteen of the most frequently sold cigarette brands produced in Vietnam were examined in this study. 210Po was determined by alpha spectroscopy using a passivated implanted planar silicon (PIPS) detector after a procedure including radiochemical separation and spontaneous deposition of polonium on a copper disc (the deposition efficiency of 210Po on a copper disc was approximately 94%). Sequentially, 210Pb was determined through the ingrowth of 210Po after storing the sample solutions for approximately six months. The activity concentrations of 210Po in cigarettes ranged from 13.8 to 82.6 mBq/cigarette (the mean value was 26.4 mBq/cigarette) and the activity concentrations of 210Pb in cigarettes ranged from 13.9 to 78.8 mBq/cigarette (the mean value was 25.8 mBq/cigarette). The annual committed effective dose for smokers who smoke one pack per day was also estimated to be 295.4 µSv/year (223.0 µSv/year and 72.4 µSv/year from 210Po and 210Pb, respectively). These indicated that smoking increased the risk of developing lung cancer was approximately 60 times greater for smokers than for non-smokers.

    Alcohol consumption is strongly associated with cigarette smoking in young adults. The primary aim of this investigation was to complete a pilot evaluation of the efficacy of an integrated intervention that targets both cigarette smoking and binge drinking on the cigarette smoking and binge behavior of young adults at 6-month follow-up. Participants were 95 young adult (M=24.3; SD=3.5 years) smokers (≥1 cigarettes per day) who binge drink (≥1 time per month) and who were randomly assigned to standard treatment (n=47) involving six individual treatment visits plus eight weeks of nicotine patch therapy or the identical smoking cessation treatment integrated with a binge drinking intervention (integrated intervention; n=48). Using an intent-to-treat analysis for tobacco abstinence, at both 3 month end of treatment and 6 month follow-up, more participants who received integrated intervention were biochemically confirmed abstinent from tobacco than those who received standard treatment at 3 months (19% vs. 9%, p=0.06) and 6 months (21% vs. 9%, p=0.05). At 6 months, participants who completed the study and who received integrated intervention consumed fewer drinks per month (psmoking cessation and reduces binge drinking compared to standard treatment.

    OBJECTIVE—To provide an understanding of the targeting strategies of cigarette marketing, and the functions and importance of the advertising images chosen.
METHODS—Analysis of historical corporate documents produced by affiliates of British American Tobacco (BAT) and RJ Reynolds (RJR) in Canadian litigation challenging tobacco advertising regulation, the Tobacco Products Control Act (1987): Imperial Tobacco Limitee & RJR-Macdonald Inc c. Le Procurer General du Canada.
RESULTS—Careful and extensive research has been employed in all stages of the process of conceiving, developing, refining, and deploying cigarette advertising. Two segments commanding much management attention are "starters" and "concerned smokers". To recruit starters, brand images communicate independence, freedom and (sometimes) peer acceptance. These advertising images portray smokers as attractive and autonomous, accepted and admired, athletic and at home in nature. For "lighter" brands reassuring health concerned smokers, lest they quit, advertisements provide imagery conveying a sense of well being, harmony with nature, and a consumer's self image as intelligent.
CONCLUSIONS—The industry's steadfast assertions that its advertising influences only brand loyalty and switching in both its intent and effect is directly contradicted by their internal documents and proven false. So too is the justification of cigarette advertising as a medium creating better informed consumers, since visual imagery, not information, is the means of advertising influence.

  2. Bronchial airway gene expression in smokers with lung or head and neck cancer

    International Nuclear Information System (INIS)

    Cigarette smoking is the major cause of cancers of the respiratory tract, including non-small cell lung cancer (NSCLC) and head and neck cancer (HNC). In order to better understand carcinogenesis of the lung and upper airways, we have compared the gene expression profiles of tumor-distant, histologically normal bronchial biopsy specimens obtained from current smokers with NSCLC or HNC (SC, considered as a single group), as well as nonsmokers (NS) and smokers without cancer (SNC). RNA from a total of 97 biopsies was used for gene expression profiling (Affymetrix HG-U133 Plus 2.0 array). Differentially expressed genes were used to compare NS, SNC, and SC, and functional analysis was carried out using Ingenuity Pathway Analysis (IPA). Smoking-related cancer of the respiratory tract was found to affect the expression of genes encoding xenobiotic biotransformation proteins, as well as proteins associated with crucial inflammation/immunity pathways and other processes that protect the airway from the chemicals in cigarette smoke or contribute to carcinogenesis. Finally, we used the prediction analysis for microarray (PAM) method to identify gene signatures of cigarette smoking and cancer, and uncovered a 15-gene signature that distinguished between SNC and SC with an accuracy of 83%. Thus, gene profiling of histologically normal bronchial biopsy specimens provided insight into cigarette-induced carcinogenesis of the respiratory tract and gene signatures of cancer in smokers

    Full Text Available Abstract Background In the last decade Poland has successfully carried out effective anti-tobacco campaigns and introduced tobacco control legislation. This comprehensive strategy has focused on the general population and has led to a considerable decrease in tobacco consumption. Prisoners constitute a relatively small part of the entire Polish population and smoking habits in this group have been given little attention. The aim of the study was to assess the prevalence of cigarette smoking in Polish male prisoners, factors determining smoking in this group, prisoners' attitudes towards smoking cessation, and to evaluate prisoners' perception of different anti-tobacco measures. Methods An anonymous questionnaire including personal, demographic and smoking data was distributed among 944 male inmates. Of these, 907 men aged between 17 and 62 years (mean 32.3 years met the inclusion criteria of the study. For the comparison of proportions, a chi-square test was used with continuity correction whenever appropriate. Results In the entire group, 81% of the subjects were smokers, 12% – ex-smokers, and 7% – never smokers. Current smokers had significantly lower education level than non-smokers (p Conclusion The prevalence of cigarette smoking among Polish prisoners is high. However, a majority of smokers attempt to quit, and they should be encouraged and supported. Efforts to reduce cigarette smoking in prisons need to take into consideration the specific factors influencing smoking habits in prisons.

  5. Macrophage-stimulating protein differently affects human alveolar macrophages from smoker and non-smoker patients: evaluation of respiratory burst, cytokine release and NF-kappaB pathway.

    Macrophage activation is a key feature of inflammatory reactions occurring during bacterial infections, immune responses and tissue injury. We previously demonstrated that human macrophages of different origin express the tyrosine kinase receptor recepteur d'origine nantaise, the human receptor for MSP (RON) and produce superoxide anion (O(2)(-)) when challenged with macrophage-stimulating protein (MSP), the endogenous ligand for RON. This study was aimed to evaluate the role of MSP in alveolar macrophages (AM) isolated from healthy volunteers and patients with interstitial lung diseases (sarcoidosis, idiopathic pulmonary fibrosis), either smokers or non-smokers, by evaluating the respiratory burst, cytokine release and nuclear factor-kappa B (NF-kappaB) activation. MSP effects were compared with those induced by known AM stimuli, for example, phorbol myristate acetate, N-formyl-methionyl-leucyl-phenylalanine, lipopolysaccharide.MSP evokes O(2)(-) production, cytokine release and NF-kappaB activation in a concentration-dependent manner. By evaluating the respiratory burst, we demonstrate a significantly increased O(2)(-) production in AM from healthy smokers or smokers with pulmonary fibrosis, as compared to non-smokers, thus suggesting MSP as an enhancer of cigarette smoke toxicity. Besides inducing interleukin-1 beta (IL-1beta) and interleukin-10 (IL-10) production, MSP triggers an enhanced tumor necrosis factor-alpha release, especially in healthy and pulmonary fibrosis smokers. On the contrary, MSP-induced IL-10 release is higher in AM from healthy non-smokers. MSP activates the transcription factor NF-kappaB; this effect is more potent in healthy and fibrosis smokers (2.5-fold increase in p50 subunit translocation). This effect is receptor-mediated, as it is prevented by a monoclonal anti-human MSP antibody. The higher effectiveness of MSP in AM from healthy smokers and patients with pulmonary fibrosis is suggestive of its role in these clinical conditions

    Diet and other risk factors for cancer of the larynx were examined in a case-control study among white males in Western New York, conducted in 1975-1985. Incident, pathologically-confirmed cases and age- and neighborhood-matched controls were interviewed to determine usual diet, and lifetime use of tobacco and alcohol. Because response rates were low for both cases and controls, this cannot be considered a population-based study. A strong association of risk with cigarette but not pipe and cigar smoking was found. Beer and hard liquor but not wine were associated with increased risk. After control for cigarettes, alcohol and education, the upper quartile odds ratio for fat was 2.40, while the odds ratio for high intake of carotenoids was 0.51. There was effect modification by smoking. Carotenoids were most negatively associated with risk among lighter smokers; dietary fat was most positively associated with risk among heavier smokers. Total calories, protein, and retinol were associated with increased risk; there was no relationship between laryngeal cancer and vitamins C and E or carbohydrate. This study again demonstrates the strong association between tobacco and alcohol and laryngeal cancer and also suggests that diets low in carotenoids and high fat may increase risk.

    2013-01-01

    Reports have suggested that the use of a dangerously tainted form of marijuana, referred to in the vernacular as "wet" or "fry," has increased. Marijuana cigarettes are dipped into or laced with other substances, typically formaldehyde, phencyclidine, or both. Inhaling smoke from these cigarettes can cause lung injuries. We report the cases of 2 young adults who presented at our hospital with respiratory failure soon after they had smoked "wet" marijuana cigarettes. In both patients, progressive hypoxemic respiratory failure necessitated rescue therapy with extracorporeal membrane oxygenation. After lengthy hospitalizations, both patients recovered with only mild pulmonary function abnormalities. To our knowledge, this is the first 2-patient report of severe respiratory failure and rescue therapy with extracorporeal oxygenation after the smoking of marijuana cigarettes thus tainted. We believe that, in young adults with an unexplained presentation of severe respiratory failure, the possibility of exposure to tainted marijuana cigarettes should be considered. PMID:23466531

    两种经验方法在这篇研究论文中使用,为了调查在美国香烟价格跟香烟需求的关系通过可以找到的数据信息。这篇论文的目的为了调查香烟的价格是否是一个强有力的方式去减少香烟的需求。论文中的的数据收集来源于美国的48个州从1985年到1995年,目的是检测香烟价格跟其他独立的变量对香烟需求的作用。最小二乘回归模型跟虚拟变量的最小二乘法模型已经使用去决定香烟价格的作用。此外,其他因素像人均GDP,人口,CPI也使用在模型中去证实潜在的关系对于香烟需求。报告结果显示了任何方式的香烟价格上升将会导致个人香烟需求的下降。香烟需求的百分比下降取决于香烟价格的百分比上升,这个现象可以通过需求的价格弹性去估量。基于报告的分析可以放心的作出结论,香烟价格上升仍然是一种有效的工具去减少香烟的需求。%In this research paper two empirical methodologies are used for studying the relation between cigarette price and cigarette consumption in America with available statistical information. The purpose of the paper is to investigate whether the price of cigarette is a powerful method for cutting cigarette consumption. The statistical information used in the paper is collected from 48 U.S. states over the period from 1985 to 1995 for examining the effect of cigarette price and others independent variables on cigarette consumption. Ordinary least squares (OLS) regression model and Least square dummy variable model are used to determine effect of cigarette price. Furthermore, other factors such as GDP per capita, population and Consumer price index (CPI), have been added into the model to attest to their potential nexuses with cigarette consumption. The result of the report shows that any increase in the price of cigarettes will decrease personal consumption of cigarettes. Higher prices increase costs to

    A hallmark of cigarette smoking is a shift in the protease/antiprotease balance, in favor of protease activity. However, it has recently been shown that smokers have increased expression of a key antiprotease, secretory leukoprotease inhibitor (SLPI), yet the mechanisms involved in SLPI transcriptional regulation and functional activity of SLPI remain unclear. We examined SLPI mRNA and protein secretion in differentiated nasal epithelial cells (NECs) and nasal lavage fluid (NLF) from nonsmokers and smokers and demonstrated that SLPI expression is increased in NECs and NLF from smokers. Transcriptional regulation of SLPI expression was confirmed using SLPI promoter reporter assays followed by chromatin immunoprecipitation. The role of STAT1 in regulating SLPI expression was further elucidated using WT and stat1(-/-) mice. Our data demonstrate that STAT1 regulates SLPI transcription in epithelial cells and slpi protein in the lungs of mice. Additionally, we reveal that NECs from smokers have increased STAT1 mRNA/protein expression. Finally, we demonstrate that SLPI contained in the nasal mucosa of smokers is proteolytically cleaved but retains functional activity against neutrophil elastase. These results demonstrate that smoking enhances expression of SLPI in NECs in vitro and in vivo, and that this response is regulated by STAT1. In addition, despite posttranslational cleavage of SLPI, antiprotease activity against neutrophil elastase is enhanced in smokers. Together, our findings show that SLPI regulation and activity is altered in the nasal mucosa of smokers, which could have broad implications in the context of respiratory inflammation and infection.

    Cigarette smoking among college students is a critical public health problem with serious personal and social consequences. This study examined college student opinions about smoking in the student cafeteria, hallways and offices, considering smoking as freedom of choice, complying with the cigarette law and policy of universities on smoking. A sample of 1527 students (53.9% female, 46.1% male) attending to the six prestigious universities in Ankara, Turkey, completed a ten-item questionnaire. Results of the study showed that nonsmoking students reported the most favorable opinions toward the issues questioned, whereas occasional smokers and regular smokers reported the least favorable opinions. The highest level of disagreement by smokers and nonsmokers was provided for banning cigarette smoking in the cafeteria. Students generally agreed on that teachers should not smoke in the classrooms and in their offices with doors open. Recommended actions include campus-wide no-smoking policies embracing indoors and outdoors and identification and use of new ways of providing smoking prevention and cessation programs and services.

    Objectives Smokers might think that the negative effects of smoking can be compensated for by other behaviours, such as doing exercise or eating healthily. This phenomenon is known as compensatory health beliefs (CHBs). Graphic warning labels on cigarette packets emphasize the negative effects of sm

    Full Text Available Abstract Background Cigarette smoking is a tough addiction to break. Therefore, improved approaches to smoking cessation are necessary. The electronic-cigarette (e-Cigarette, a battery-powered electronic nicotine delivery device (ENDD resembling a cigarette, may help smokers to remain abstinent during their quit attempt or to reduce cigarette consumption. Efficacy and safety of these devices in long-term smoking cessation and/or smoking reduction studies have never been investigated. Methods In this prospective proof-of-concept study we monitored possible modifications in smoking habits of 40 regular smokers (unwilling to quit experimenting the 'Categoria' e-Cigarette with a focus on smoking reduction and smoking abstinence. Study participants were invited to attend a total of five study visits: at baseline, week-4, week-8, week-12 and week-24. Product use, number of cigarettes smoked, and exhaled carbon monoxide (eCO levels were measured at each visit. Smoking reduction and abstinence rates were calculated. Adverse events and product preferences were also reviewed. Results Sustained 50% reduction in the number of cig/day at week-24 was shown in 13/40(32.5% participants; their median of 25 cigs/day decreasing to 6 cigs/day (p Conclusion The use of e-Cigarette substantially decreased cigarette consumption without causing significant side effects in smokers not intending to quit (http://ClinicalTrials.gov number NCT01195597.

    Active marijuana produces significant subjective, psychomotor, and physiological effects relative to inactive marijuana, yet demonstrating that these effects are dose-dependent has proven difficult. This within-subject, double-blind study was designed to develop a smoking procedure to obtain a marijuana dose-response function. In four outpatient laboratory sessions, daily marijuana smokers (N = 17 males, 1 female) smoked six 5-s puffs from 3 marijuana cigarettes (2 puffs/cigarette). The number of puffs from active (≥5.5% Δ⁹-tetrahydrocannabinol/THC) and inactive (0.0% THC) marijuana varied according to condition (0, 2, 4, or 6 active puffs); active puffs were always smoked before inactive puffs. Subjective, physiological, and performance effects were assessed prior to and at set time points after marijuana administration. Active marijuana dose-dependently increased heart rate and decreased marijuana craving, despite evidence (carbon monoxide expiration, weight of marijuana cigarettes post-smoking) that participants inhaled less of each active marijuana cigarette than inactive cigarettes. Subjective ratings of marijuana "strength," "high," "liking," "good effect," and "take again" were increased by active marijuana compared with inactive marijuana, but these effects were not dose-dependent. Active marijuana also produced modest, non-dose-dependent deficits in attention, psychomotor function, and recall relative to the inactive condition. In summary, although changes in inhalation patterns as a function of marijuana strength likely minimized the difference between dose conditions, dose-dependent differences in marijuana's cardiovascular effects and ratings of craving were observed, whereas subjective ratings of marijuana effects did not significantly vary as a function of dose.

    Through Pavlovian conditioning, reward-associated neutral stimuli can acquire incentive salience and motivate complex behaviors. In smokers, cigarette-associated cues may induce cravings and trigger smoking. Understanding the brain mechanisms underlying conditioned responses to cigarette-associated relative to other inherently pleasant stimuli might contribute to the development of more effective smoking cessation treatments that emphasize the rehabilitation of reward circuitry. Here we measured brain responses to geometric patterns (the conditioned stimuli, CSs) predicting cigarette-related, intrinsically pleasant and neutral images (the unconditioned stimuli, USs) using event-related potentials (ERPs) in 29 never-smokers, 20 nicotine-deprived smokers, and 19 non-deprived smokers. Results showed that during US presentation, cigarette-related and pleasant images prompted higher cortical positivity than neutral images over centro-parietal sensors between 400 and 800ms post-US onset (late positive potential, LPP). The LPP evoked by pleasant images was significantly larger than the LPP evoked by cigarette images. During CS presentation, ERPs evoked by geometric patterns predicting pleasant and cigarette-related images had significantly larger amplitude than ERPs evoked by CSs predicting neutral images. These effects were maximal over right parietal sites between 220 and 240ms post-CS onset and over occipital and frontal sites between 308 and 344ms post-CS onset. Smoking status did not modulate these effects. Our results show that stimuli with no intrinsic reward value (e.g., geometric patterns) may acquire rewarding properties through repeated pairings with established reward cues (i.e., cigarette-related, intrinsically pleasant).

    Full Text Available Context: In Saudi Arabia, no studies have been conducted on the correlation between any possible cigarette′s price increase and its effects on cigarette consumption. Aims: The aim of this study was to determine the prevalence of cigarette smoking in Saudi Arabia and to predict the effect of price increase on cigarette consumption. Settings and Design: A cross-sectional study was conducted in April and May 2013. Methods: We developed an Arabic questionnaire with information on demographic and socioeconomic factors, smoking history, and personal opinion on the effect of price increase on cigarette consumption. The questionnaire was distributed in public places such as malls and posted on famous Saudi athlete media′s twitter accounts. Results: Among the 2057 included responses, 802 (39% were current smokers. The smokers′ population constituted of 746 (92% males, of which 546 (68% had a monthly income equal or greater to 800 US dollars, and 446 (55% were aged between 21 and 30 years. Multivariate analyses of the risk factors for smoking showed that male gender and older age were associated with greater risk. Despite the current low prices of 2.67 US dollars, 454 smokers (56% thought that cigarette prices are expensive. When asked about the price of cigarettes that will lead to smoking cessation, 443 smokers (55% expected that a price of 8.27 US dollars and more per pack will make them quit. Conclusions: Increasing the price of popular cigarettes pack from 2.67 US dollars to 8.27 US dollars is expected to lead to smoking cessation in a large number of smokers in the Saudi population.

    Full Text Available Abstract Objective To learn how cigarette packages are designed and to determine to what extent cigarette packages are designed to target children. Methods A computer search was made of all Internet websites that post tobacco industry documents using the search terms: packaging, package design, package study, box design, logo, trademark and design study. All documents were retrieved electronically and analyzed by the first author for recurrent themes. Data Synthesis Cigarette manufacturers devote a great deal of attention and expense to package design because it is central to their efforts to create brand images. Colors, graphic elements, proportioning, texture, materials and typography are tested and used in various combinations to create the desired product and user images. Designs help to create the perceived product attributes and project a personality image of the user with the intent of fulfilling the psychological needs of the targeted type of smoker. The communication of these images and attributes is conducted through conscious and subliminal processes. Extensive testing is conducted using a variety of qualitative and quantitative research techniques. Conclusion The promotion of tobacco products through appealing imagery cannot be stopped without regulating the package design. The same marketing research techniques used by the tobacco companies can be used to design generic packaging and more effective warning labels targeted at specific consumers.
