Development and initial validation of a new self-report measure to assess perceived dependence on tobacco and nicotine products. Sci Rep 2024; 14:10098. [PMID: 38698227 PMCID: PMC11066063 DOI: 10.1038/s41598-024-60790-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Accepted: 04/26/2024] [Indexed: 05/05/2024] Open
Abstract
How nicotine is administered has evolved from cigarettes to various delivery systems. Assessing perceived dependence on nicotine-containing products now requires accounting for product specificity while allowing comparisons across products and users. This study aims to develop a new self-report measure to assess perceived dependence on tobacco and nicotine products (TNPs) among exclusive and poly-TNP users. A draft version of the new measure, the ABOUT-Dependence, was constructed based on literature review, qualitative research, and expert opinion. Data for scale formation and psychometric assessment was obtained through a US-based web survey (n = 2334) that included additional dependence measures for convergent validity assessment. Qualitative research confirmed a preliminary conceptual framework with seven sub-concepts. Following a cognitive debriefing, 19 items were considered to best represent the different sub-concepts. Psychometric findings supported a three-domain structure [i.e., behavioral impact (five items), signs and symptoms (five items), and extent/timing of use (two items)] and an overall total composite score. The data confirmed convergent and known-group validity, as well as test-retest reliability. The ABOUT-Dependence is a 12-item, psychometrically sound, self-report measure that may be used as a tool for research and further understanding of perceived dependence across the spectrum of TNP and TNP users.

Abstract
BACKGROUND Substance use behaviours (SUB) including smoking, alcohol consumption, and coffee intake are associated with many health outcomes. However, whether the health effects of SUB are causal remains controversial, especially for alcohol consumption and coffee intake. METHODS In this study, we assess 11 commonly used Mendelian Randomization (MR) methods by simulation and apply them to investigate the causal relationship between 7 SUB traits and health outcomes. We also combine stratified regression, genetic correlation, and MR analyses to investigate the dosage-dependent effects. RESULTS We show that smoking initiation has widespread risk effects on common diseases such as asthma, type 2 diabetes, and peripheral vascular disease. Alcohol consumption shows risk effects specifically on cardiovascular diseases, dyslipidemia, and hypertensive diseases. We find evidence of dosage-dependent effects of coffee and tea intake on common diseases (e.g., cardiovascular disease and osteoarthritis). We observe that the minor allele effect of rs4410790 (the top signal for tea intake level) is negative on heavy tea intake ( b ̂ G W A S = - 0.091 , s . e . = 0.007 , P = 4.90 × 10 - 35 ) but positive on moderate tea intake ( b ̂ G W A S = 0.034 , s . e . = 0.006 , P = 3.40 × 10 - 8 ) , compared to the non-tea-drinkers. CONCLUSION Our study reveals the complexity of the health effects of SUB and informs design for future studies aiming to dissect the causal relationships between behavioural traits and complex diseases.

Lund KE, Saebo G. Challenges in legitimizing further measures against smoking in jurisdictions with robust infrastructure for tobacco control: how far can the authorities allow themselves to go? Harm Reduct J 2024; 21:33.

Abstract
BACKGROUND According to a recently published study, approximately half of those who currently smoke in Norway have little or no desire to quit despite a hostile regulatory and socio-cultural climate for smoking. On this background, we discuss some challenges that regulators will face in a further tightening of structural measures to curb smoking. MAIN BODY Central to our discussion is the research literature concerned with the concept of state-paternalism in tobacco control-the line between an ethically justified interference with the freedom of those who smoke and an exaggerated infringement disproportionate to the same people's right to live as they choose. In countries with an already advanced infrastructure for tobacco control, this dilemma might become quite intrusive for regulators. We ask that if people, who smoke are aware of and have accepted the risks, are willing to pay the price, smoke exclusively in designated areas, and make decisions uninfluenced by persuasive messages from manufacturers-is a further tightening of anti-smoking measures still legitimate? Strengthening of the infrastructure for tobacco control can be seen as a "help" to people who-due to some sort of "decision failure"-continue to smoke against their own will. However, for those who want to continue smoking for reasons that for them appear rational, such measures may appear unwanted, punitive, and coercive. Is it within the rights of regulators to ignore peoples' self-determination for the sake of their own good? We problematize the "help" argument and discuss the authorities' right to elevate the zero-vision of smoking as universally applicable while at the same time setting up barriers to switching to alternative nicotine products with reduced risk. CONCLUSION We recommend that a further intensification of smoking control in countries that already have a well-developed policy in this area requires that regulators start to exploit the opportunity that lies in the ongoing diversification of the recreational nicotine market.

Abstract
Introduction Most adult cigarette smokers have tried unsuccessfully to quit. We followed participants in the Population Assessment of Tobacco and Health (PATH) study through five waves (2013-2019), comparing smoking, quit behaviors and other characteristics between persistent smokers and those who became and stayed former smokers. Methods The main analysis employed treatment effects to estimate mean differences in smoking and quitting behaviors among smoker groups. Logistic models were used to estimate predicted means based on continuing smokers' demographic characteristics to ensure that any differences in outcomes did not come from differences in demographic characteristics. Results Among smokers enrolled in PATH Wave 1, 68 % persisted in all subsequent waves. Compared with smokers who quit after Wave 1, persistent smokers had remarkably stable smoking behaviors, including significantly higher proportions of everyday smokers, consuming 10+ cigarettes per day, and smoking within 30 min of waking up. Persistent smokers were also less likely to try to quit completely, and experienced more negative symptoms from nicotine withdrawal. They also showed less interest in quitting and were less confident of being successful than smokers who quit by the next wave. Neither electronic nicotine delivery systems nor menthol played a role in continued smoking or quitting. Conclusions The characteristics and behaviors of persistent smokers in this study were stable over five waves of data collection during a six-year period, suggesting that these smokers need new cessation options.

Abstract
PURPOSE OF REVIEW Tobacco use is associated with significant health consequences especially for people with medical conditions. Although lifestyle strategies (e.g., sleep, diet) are commonly recommended as part of migraine treatment, tobacco-related strategies (e.g., smoking cessation) are rarely included. This review is aimed at elucidating what is known about tobacco use and migraine and at identifying gaps in the research. RECENT FINDINGS The prevalence of smoking is higher among people with migraine, and people with migraine believe that smoking makes migraine attacks worse. There is also evidence that smoking may exacerbate migraine-related consequences (e.g., stroke). Very few studies have examined other aspects of smoking and migraine or tobacco products other than cigarettes. There are significant gaps in our knowledge of smoking and migraine. More research is needed to understand the relationship of tobacco use to migraine and potential benefits of adding smoking cessation efforts into migraine care.

Abstract
Introduction First aiders are commonly exposed to different forms of traumatic event (TE) during their duties, such as Chronic Indirect Vicarious Exposure which refers to an indirect exposure to aversive details of the trauma (APA, 2013). If the psychopathological impact of TE is well documented, the mental health of first aiders remains neglected. Therefore, our main objectives are (i) to study the link between exposure to traumatic events and psychopathological outcomes and (ii) to quantify the rates of mental health disorders among first aiders. Method Our sample comprised of 53 volunteer first aiders (21 females and 32 males) with an average age of 32.4 years (SD = 13.6 years). Traumatic event exposure and mental health were assessed through a set of validated questionnaires completed online. Results Rates of mental health outcomes were higher than within the general population. Females showed higher scores of post-traumatic stress disorder (PTSD) than males. PTSD scores were significantly correlated with all mental issues scores, apart from tobacco use and eating disorders scores. There was a significant correlation between the number of traumatic events and the years of experience. Exposure to traumatic events only correlated with nicotine dependency. No other correlation reaches statistical significance. Discussion The scores of all mental health outcomes were high; a surprising result, as volunteer first aiders are thought to be recruited for their strong dispositional cognitive and emotional abilities. The high levels of post-traumatic stress disorder and burnout, along with the prevalent anxiety and depression, highlight the need for greater psychosocial support. Resilience training and peer support would be useful interventions in this group.

Abstract
The salience network, including the insula and anterior cingulate cortex (ACC), has been implicated in nicotine addiction. Structural imaging studies have reported diminished insula and ACC gray matter volumes (GMVs) in smokers as compared to nonsmokers. However, it remains unclear how insula and ACC GMVs may relate to years of smoking, addiction severity, or behavioral traits known to dispose individuals to smoking. Here, with a dataset curated from the Human Connectome Project and voxel-based morphometry, we replicated the findings of smaller GMVs of the insula and medial prefrontal cortex, including the dorsal ACC and supplementary motor area (dACC/SMA), in (70 heavy < 209 light < 209 never) smokers matched in age, sex, and average daily num ber of drinks. The GMVs of the insula or dACC/SMA were not significantly correlated with years of smoking or Fagerstrom Test for Nicotine Dependence (FTND) scores. Heavy relative to never smokers demonstrated higher externalizing and internalizing scores, as evaluated by the NIH Emotion. In heavy smokers, the dACC/SMA but not insula GMV was positively correlated with both externalizing and internalizing scores. The findings together confirm volumetric changes in the salience network in heavy smokers and suggest potentially distinct dysfunctional roles of the insula and dACC/SMA in chronic smoking.

Abstract
SIGNIFICANCE Cannabis use is increasing among cigarette smokers. If cannabis use is associated with cigarette dependence, a barrier to smoking cessation, this could have public health implications for tobacco control. The current study estimated the prevalence of cigarette dependence among US individuals who smoke cigarettes by cannabis use status, and investigated trends in cigarette dependence from 2002 to 2019 among cigarette smokers by cannabis use status and cigarette consumption (ie, cigarettes per day, CPD). METHODS Data were drawn from the 2002-2019 annual National Survey on Drug Use and Health and included US individuals aged 12+ years who used cigarettes at least once in the past month (n=231 572). Logistic regression was used to estimate the prevalence of cigarette dependence, measured as time to first cigarette <30 min, by past-month cannabis use (no use, non-daily use, daily use), and to estimate trends in cigarette dependence from 2002 to 2019 overall and stratified by cannabis use and smoking level (light, 1-5 CPD; moderate, 6-15 CPD; heavy, 16+ CPD). RESULTS Across all levels of cigarette use, cigarette dependence was significantly more common among individuals with daily cannabis use compared with those with non-daily or no cannabis use. From 2002 to 2019, cigarette dependence increased among cigarette smokers with non-daily cannabis use, and among light and moderate cigarette smokers with no cannabis use. CONCLUSIONS US individuals who use both cigarettes and cannabis report a higher prevalence of cigarette dependence relative to individuals who use cigarettes and do not use cannabis at virtually all levels of cigarette consumption. Further, cigarette dependence is increasing in the USA both among those who use and do not use cannabis. Given the increase in cannabis use among those using cigarettes, efforts to elucidate the nature of the association between cannabis and cigarette dependence are needed.

Abstract
INTRODUCTION Sexual minorities are at increased risk for tobacco use; however, there is heterogeneity in this risk by sociodemographic factors. AIMS AND METHODS This study sought to understand if vulnerability to tobacco use among US sexual minorities varies by age group. For this study we used data from wave 4 of the Population Assessment of Tobacco and Health adolescent and adult surveys (n = 37 959), a nationally representative survey. We examined five nicotine/tobacco use outcomes by sex and sexual identity across four age groups. The five outcomes included past 30-day e-cigarette use, past 30-day cigarette use, past 30-day other tobacco use, the number of tobacco products used, and nicotine dependence symptoms. RESULTS For males, sexual identity differences were greatest in middle adulthood, particularly for bisexual males; adjusted odds ratios and adjusted incident rate ratios ranged from 2.08 to 5.59 in middle adulthood compared to 0.83-1.62 in adolescence. For females, sexual identity differences were persistent from adolescence through middle adulthood. We found significant differences most consistently for nicotine dependence symptoms when comparing gay/lesbian and bisexual females across multiple age groups; adjusted incident rate ratios ranged from 1.90 in middle adulthood to 3.26 in adolescence. CONCLUSIONS Risk among sexual minorities varied considerably across age groups and by nicotine/tobacco product and severity of symptoms. Our findings underscore the importance of looking beyond single tobacco products when examining nicotine/tobacco differences related to sexual identity and in examining differences by age group. Our results demonstrating age-varying risk among sexual minorities have important implications for tobacco prevention and cessation efforts. IMPLICATIONS This study identifies important age variation in sexual minority differences in tobacco use, particularly among males. This study also shows that many sexual minorities not only have higher risk for tobacco and nicotine product use but also use significantly more tobacco products and have higher nicotine dependence symptom scores. These results have important implications for implementation of nicotine and tobacco prevention and cessation strategies for sexual minority adolescents and adults.

Abstract
We examined the role of depressive symptoms in the longitudinal trajectory of the number of tobacco products used across young adulthood, ages 18-30 years, and whether peer tobacco use exacerbated the effects of the depressive symptoms. Participants were 4534 initially 18-25-year-old young adults in the Marketing and Promotions Across Colleges in Texas project (Project M-PACT), which collected data across a 4.5-year period from 2014 to 2019. Growth curve modeling within an accelerated design was used to test study hypotheses. Elevated depressive symptoms were associated with a greater number of tobacco products used concurrently and at least six months later. The number of tobacco-using peers moderated the association between depressive symptoms and the number of tobacco products trajectory. Young adults with elevated depressive symptoms used a greater number of tobacco products but only when they had a greater number of tobacco-using peers. Findings indicate that not all young adults with depressive symptoms use tobacco. Having a greater number of tobacco-using peers may facilitate a context that both models and encourages tobacco use. Therefore, tobacco prevention programs should aim to include peer components, especially for young adults.

Abstract
INTRODUCTION Cigarette smoking prevalences are very high in persons living with HIV (PLWH). Identifying variables among PLWH that are linked to smoking in community samples (e.g., self-control) can inform smoking treatments for PLWH. The current study examined the association of self-reported self-control and smoking (e.g., smoking status, cigarette dependence) in a sample of PLWH. METHODS Adult PLWH were recruited from the Center for Positive Living (Montefiore Medical Center, Bronx, New York, US). All participants completed measures of demographics, cigarette smoking, and self-control. Participants who reported current cigarette smoking completed measures of cigarette dependence; intolerance for smoking abstinence; and motivation, confidence, and desire to quit smoking. RESULTS The overall sample included 285 PLWH (49.1% cigarette users, 55.4% male, 52.7% Black race, 54.8% Latino/a ethnicity). PLWH with current cigarette smoking reported lower self-control than PLWH with no current cigarette smoking (M = 116.88, SD = 17.07 versus M = 127.39, SD = 20.32; t = -4.15, df = 211, p < 0.001). Among PLWH with current cigarette smoking, lower self-control was associated with greater cigarette dependence (ρ = -0.272, p < 0.01), and lower confidence in quitting smoking cigarettes (ρ = 0.214, p < 0.05). Lower self-control was associated with greater overall smoking abstinence intolerance (ρ = -0.221, p < 0.05) and withdrawal intolerance (ρ = -0.264, p < 0.01). DISCUSSION Among a sample of PLWH, lower self-control was related to cigarette smoking (versus no smoking), greater cigarette dependence, lower confidence in quitting smoking, and greater intolerance for smoking abstinence. It may be useful to target self-control among PLWH to increase confidence in quitting and abstinence intolerance with the goal of improving smoking cessation outcomes.

Abstract
OBJECTIVE Nationally representative data on changes in 12-month prevalences of nicotine use, DSM-IV nicotine dependence, and DSM-IV nicotine dependence among users were analyzed to test the "hardening hypothesis," which proposes that declines in nicotine use resulting from population-level control measures leave a growing proportion of highly dependent users. METHODS Data were derived from two nationally representative surveys of U.S. adults: the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC, N=43,093) and the 2012-2013 NESARC-III (N=36,309). Weighted estimates of nicotine use, DSM-IV nicotine dependence, and an approximation of the Fagerström Test for Nicotine Dependence were compared for the 2001-2002 NESARC and 2012-2013 NESARC-III among the overall population and among nicotine users. Adjusted risk differences were obtained from logistic regression analyses using the predicted marginal approach. RESULTS Between the 2001-2002 and 2012-2013 surveys, rates of 12-month nicotine use declined slightly (from 27.7% to 26.9%), but increased slightly but significantly when adjusted for sociodemographic characteristics (adjusted risk difference=1.4%). Larger significant increases were seen in 12-month nicotine dependence (adjusted risk difference=2.6%) and nicotine dependence among users (adjusted risk difference=6.4%). With few exceptions, increases in nicotine use, nicotine dependence, and nicotine dependence among users were statistically significant across most sociodemographic subgroups. Notable increases were seen among men; middle and older age groups; whites, blacks, and Hispanics; and the socioeconomically disadvantaged. CONCLUSIONS Smaller increases in 12-month nicotine use relative to larger increases in 12-month nicotine dependence and nicotine dependence among users suggests that increases in nicotine dependence between the 2001-2002 and 2012-2013 surveys are findings that support the hardening hypothesis. Vulnerable subgroups of the population in terms of hardening were identified who would benefit from targeted nicotine dependence intervention programs to help them in overcoming dependence and quitting nicotine use.

Abstract
BACKGROUND AND AIMS Cigarette smoking often results in nicotine dependence. With use of electronic cigarettes as an alternative source of nicotine, it is important to assess dependence associated with e-cigarette use. This study assesses dependence among current and former adult e-cigarette users on cigarettes and e-cigarettes, compared with dependence on cigarettes. DESIGN Cross-sectional data from the Population Assessment of Tobacco and Health (PATH) study from 2013-2016. Psychometrically assessed dependence was compared for cigarettes and e-cigarettes among current and former exclusive and dual users of the products and among e-cigarette users who had and had not recently stopped smoking. Setting A population-based representative sample of US adults. Participants Participants were 13 311 US adults (18+) in Waves 1-3 of PATH reporting current established smoking, current use of e-cigarettes, or stopping use of either product in the past year who were administered dependence assessments for cigarettes and/or e-cigarettes. Measurements A 16-item scale assessing tobacco dependence (on a 1-5 scale), previously validated for assessment and comparison of dependence on varied tobacco products, including cigarettes and e-cigarettes, with a variation assessing residual dependence among users who stopped in the past year. Findings Among current users, dependence on e-cigarettes was significantly lower than dependence on cigarettes, in within-subjects comparisons among dual users of both e-cigarettes and cigarettes (1.58 [SE = 0.05] vs. 2.76 [0.04]), P < 0.0001), and in separate groups of e-cigarette users and cigarette smokers (1.95 [0.05] vs. 2.52 [0.02], P < 0.0001), and among both daily and non-daily users of each product. Among former users, residual symptoms were significantly lower for e-cigarettes than cigarettes, both among former dual users (1.23 [0.07] vs. 1.41 [0.06], P < 0.001) and among users of one product (1.28 [0.03] vs. 1.53 [0.03], P < 0.0001). The highest level of e-cigarette dependence was among e-cigarette users who had stopped smoking (2.17 [0.08]). Conclusion Use of e-cigarettes appears to be consistently associated with lower nicotine dependence than cigarette smoking.

Abstract
Smoking is the leading preventable cause of death worldwide and tobacco addiction has become a serious public health problem. Nicotine is the main addictive component of tobacco, and the majority of people that smoke regularly develop nicotine dependence. Nicotine addiction is deemed to be a chronic mental disorder. Although it is well known that nicotine binds to the nicotinic acetylcholine receptors (nAChRs) and activates the mesolimbic dopaminergic system (MDS) to generate the pleasant and rewarding effects, the molecular mechanisms of nicotine addiction are not fully understood. Brain-derived neurotrophic factor (BDNF) is the most prevalent growth factor in the brain, which regulates neuron survival, differentiation, and synaptic plasticity, mainly through binding to the high affinity receptor tyrosine kinase receptor B (TrkB). BDNF gene polymorphisms are associated with nicotine dependence and blood BDNF levels are altered in smokers. In this review, we discussed the effects of nicotine on BDNF expression in the brain and summarized the underlying signaling pathways, which further indicated BDNF as a key regulator in nicotine dependence. Further studies that aim to understand the neurobiological mechanism of BDNF in nicotine addcition would provide a valuable reference for quitting smoking and developing the treatment of other addictive substances.

Abstract
The present study aimed to replicate the finding that younger age predicts higher pre quit-day attrition. Our second aim was to explain this relation by examining empirically and theoretically informed age-related risk factors for low smoking cessation treatment engagement. 136 participants (Mage = 44.2 years, SD = 11.3 years; age = 22-64 years) were randomized to 15-weeks of either 1) an exercise intervention (n = 72) or 2) a wellness education control condition (n = 64). First, a logistic regression analysis was employed to test whether younger adults were more likely than older adults to drop prior to quit date. Next, we assessed whether smoking related health concerns, social expectancies, and/or perceived severity of craving affected the strength of the relation between age and attrition, by adding these three variables to the logistic regression along with age. The logistic regression model indicated that younger age and treatment condition were significantly related to the odds of dropping from treatment prior to the scheduled quit date. Further, health concerns, social expectancies, and/or perceived severity of cravings did not account for the effect of age on pre quit-day attrition. These findings highlight the importance of identifying empirically and theoretically informed variables associated with the pre quit-day attrition problem of young smokers.

Abstract
INTRODUCTION Reducing adverse events from pharmacologic treatment is an important goal of precision medicine and identifying genetic predictors of adverse events is a step toward this goal. In 2012, King et al. reported associations between genetic variants and adverse events in a placebo-controlled smoking cessation trial of varenicline and bupropion. Strong associations were found between gastrointestinal adverse events and 11 variants in the CHRNA5-CHRNA3-CHRNB4 region of chromosome 15, a region repeatedly associated with smoking-related phenotypes. Our goal was to replicate, in an independent sample, the impact of variants in the CHRNA5-CHRNA3-CHRNB4 region on gastrointestinal adverse events and to extend the analyses to adherence and smoking cessation. METHODS The University of Wisconsin Transdisciplinary Tobacco Use Research Center (TTURC) conducted a multiarmed, placebo-controlled smoking cessation trial of bupropion and nicotine replacement therapy that included 985 genotyped European-ancestry participants. We evaluated relationships between our key variables using logistic regression. RESULTS Gastrointestinal adverse events were experienced by 31.6% TTURC participants. Each of the CHRNA5-CHRNA3-CHRNB4 associations from the King et al. study was found in TTURC, with the same direction of effect. Neither these variants nor the gastrointestinal adverse events themselves were associated with adherence to medication or successful smoking cessation. CONCLUSIONS Variants in the CHRNA5-CHRNA3-CHRNB4 region of chromosome 15 are associated with gastrointestinal adverse events in smoking cessation. Additional independent variants in this region strengthen the association. The consistency between the results of these two independent studies supports the conclusion that these findings reflect biological response to the use of smoking cessation medication. IMPLICATIONS The fact that our findings from the TTURC smoking cessation trial support the independent findings of King et al. suggest that associations of variants in the CHRNA5-CHRNA3-CHRNB4 region of chromosome 15 with gastrointestinal adverse events while taking medications for smoking cessation reflect biology. However, although adherence to medication was a strong predictor of successful smoking cessation in TTURC, neither adverse events nor the genetic variants associated with them predicted either adherence or successful cessation in this study. Thus, although we should strive to minimize adverse events during treatment, we should not expect that to increase successful smoking cessation substantially.

Abstract
Waterpipe smoking (WPS) is one of the most emerging popular trends in Lebanon, with a prevalence of 36.9%, the highest among all Middle Eastern countries. Thus, the primary objective of the study was to examine the factors associated with knowledge, attitudes, and practice (KAP) related to WPS among a representative sample of waterpipe smokers. The secondary objective was to examine the effect of KAP on cumulative waterpipe dose and dependence. This cross-sectional study was carried out between May and December 2018 and enrolled a representative sample of 1550 waterpipe smokers from all Lebanese districts. The questionnaire used was specifically designed for this study. High knowledge score (Beta = 0.02, p = 0.002) were significantly associated with higher waterpipe harm perception score. In addition, high knowledge score (Beta = 0.32, p = 0.007) were significantly associated with higher attitude score toward smoking ban. Higher waterpipe harm perception score (Beta = - 1.30, p < 0.001), higher attitude (Beta = - 0.21, p < 0.001), and higher knowledge score (Beta = - 0.11, p < 0.001) were significantly associated with lower waterpipe dependence. In addition, higher waterpipe dependence (Beta = 2.02, p < 0.001) was significantly associated with higher cumulative waterpipe smoking, while higher waterpipe harm perception score (Beta = - 1.96, p = 0.009) and higher knowledge score (Beta = 0.27, p < 0.001) were significantly associated with lower cumulative waterpipe smoking. Our main finding was that better knowledge and perception of the harmful effects of waterpipe were related to a better attitude toward smoking bans and a lower waterpipe smoking. Therefore, health care providers and policymakers should join efforts to make awareness campaigns across Lebanon and develop adequate interventions to curb the use of waterpipe among the population.

Abstract
Supplemental Digital Content is available in the text. Background Rare variants (minor allele frequency < 1% or 5 %) can help researchers to deal with the confounding issue of ‘missing heritability’ and have a proven role in dissecting the etiology for human diseases and complex traits. Methods We extended the combined multivariate and collapsing (CMC) and weighted sum statistic (WSS) methods and accounted for the effects of population stratification and subgroup effects using stratified analyses by the principal component analysis, named here as ‘str-CMC’ and ‘str-WSS’. To evaluate the validity of the extended methods, we analyzed the Genetic Architecture of Smoking and Smoking Cessation database, which includes African Americans and European Americans genotyped on Illumina Human Omni2.5, and we compared the results with those obtained with the sequence kernel association test (SKAT) and its modification, SKAT-O that included population stratification and subgroup effect as covariates. We utilized the Cochran–Mantel–Haenszel test to check for possible differences in single nucleotide polymorphism allele frequency between subgroups within a gene. We aimed to detect rare variants and considered population stratification and subgroup effects in the genomic region containing 39 acetylcholine receptor-related genes. Results The Cochran–Mantel–Haenszel test as applied to GABRG2 (P = 0.001) was significant. However, GABRG2 was detected both by str-CMC (P= 8.04E-06) and str-WSS (P= 0.046) in African Americans but not by SKAT or SKAT-O. Conclusions Our results imply that if associated rare variants are only specific to a subgroup, a stratified analysis might be a better approach than a combined analysis.

Abstract
BACKGROUND AND AIMS The associations between low educational attainment and substance use disorders (SUDs) may be related to a common genetic vulnerability. We aimed to elucidate the associations between polygenic scores for educational attainment and clinical criterion counts for three SUDs (alcohol, nicotine and cannabis). DESIGN Polygenic association and sibling comparison methods. The latter strengthens inferences in observational research by controlling for confounding factors that differ between families. SETTING Six sites in the United States. PARTICIPANTS European ancestry participants aged 25 years and older from the Collaborative Study on the Genetics of Alcoholism (COGA). Polygenic association analyses included 5582 (54% female) participants. Sibling comparisons included 3098 (52% female) participants from 1226 sibling groups nested within the overall sample. MEASUREMENTS Outcomes included criterion counts for DSM-5 alcohol use disorder (AUDSX), Fagerström nicotine dependence (NDSX) and DSM-5 cannabis use disorder (CUDSX). We derived polygenic scores for educational attainment (EduYears-GPS) using summary statistics from a large (> 1 million) genome-wide association study of educational attainment. FINDINGS In polygenic association analyses, higher EduYears-GPS predicted lower AUDSX, NDSX and CUDSX [P < 0.01, effect sizes (R2 ) ranging from 0.30 to 1.84%]. These effects were robust in sibling comparisons, where sibling differences in EduYears-GPS predicted all three SUDs (P < 0.05, R2 0.13-0.20%). CONCLUSIONS Individuals who carry more alleles associated with educational attainment tend to meet fewer clinical criteria for alcohol, nicotine and cannabis use disorders, and these effects are robust to rigorous controls for potentially confounding factors that differ between families (e.g. socio-economic status, urban-rural residency and parental education).

Abstract
Little research has evaluated whether conflicting evidence for gender and racial/ethnic differences in nicotine dependence (ND) may be attributed to differences in psychometric properties of ND symptoms, particularly for young Hispanic smokers. Inadequate racial/ethnic diversity and limited smoking exposure variability has hampered research in young smokers. We used integrative data analysis (IDA) to pool DSM-IV ND symptom data for current smokers aged 12-25 (N = 20,328) from three nationally representative surveys (1999, 2000 National Surveys on Drug Use and Health (NSDUH) and Wave 1 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Moderated nonlinear factor analysis (MNLFA) tested symptom measurement invariance in the pooled sample containing greater ethnic and smoking exposure variability. There was study noninvariance for most symptoms. NESARC participants were more likely to report tolerance, using larger amounts or for longer periods, inability to cut down/quit, and more time spent smoking at higher levels of ND severity, but reported emotional/physical health problems at lower ND severity. Four symptoms showed gender or race/ethnicity noninvariance, but observed differences were small. An ND severity factor score adjusting for symptom noninvariance related to study membership, gender, and race/ethnicity did not differ substantively from traditional DSM-IV diagnosis and number of endorsed symptoms in estimated gender and race/ethnicity differences in ND. Results were consistent with studies finding minimal gender and racial/ethnic differences in ND, and suggest that symptom noninvariance is not a major contributor to observed differences. Results support IDA as a potentially promising approach for testing novel ND hypotheses not possible in independent studies.

Abstract
Loneliness is a subjective and emotionally unpleasant experience of perceiving insufficient social relationships. Previous research has revealed that loneliness constitutes a psychosocial risk factor for depression, and is also related to unhealthy behaviors such as smoking. This study aims to examine the relation between loneliness, depression, and cigarette dependence, and to explore the role of sex in this relationship. A total sample of 275 adult treatment-seeking daily smokers (Mage = 45.3; 61.5% females) was used. Our results showed a significant correlation between higher scores of loneliness, depressive symptoms, and cigarette dependence. In addition, mediation analysis showed a significant indirect effect of loneliness on cigarette dependence, via depressive symptoms. Regarding the effect of sex, we found that this variable significantly moderated the relationship between depressive symptoms and cigarette dependence. Results of this study extend previous literature by showing that, in treatment seeking smokers, loneliness is a significant predictor of depressive symptoms, and through this relation, it predicts cigarette dependence. Additionally, sex was a significant moderator of this relation. These findings have several clinical implications, and also contribute to the understanding of cigarette dependence, which is a well-known barrier for smoking cessation.

Abstract
OBJECTIVE This study examined the differential relationship of externalizing behavior, internalizing behavior, social context, and their interactions to three developmental indicators of smoking involvement: onset (age), amount of smoking, and dependence symptomatology. METHOD Participants (n = 504, 73% male) from a high-risk community-based longitudinal study were followed from age 12-14 to young adulthood (18-20). Smoking involvement was conceptualized as a process involving differences in (a) age of onset of smoking, (b) amount of smoking at age 18-20, and (c) level of nicotine dependence symptomatology at age 18-20. Survival analysis was used to predict onset of smoking, regression for smoking level, and zero-inflated Poisson regression for nicotine dependence. RESULTS Externalizing (teacher report) and internalizing behavior (youth self-report), prior to the onset of smoking, predicted different components of smoking and nicotine dependence in young adulthood. Parental smoking predicted all levels of smoking involvement. Peer smoking was related to early onset of smoking, but not higher levels of smoking involvement. Externalizing and internalizing behavior interacted to predict nicotine dependence level, with higher levels of internalizing behavior predicting higher levels of dependence symptoms, even at low levels of externalizing behavior. CONCLUSIONS Externalizing and internalizing behavior and social context are independent and interacting risk factors that come into play at different points in the developmental process occurring between smoking onset and dependence. This study provides important information for theoretical models of smoking progression and shows that different types of risk should be targeted for prevention at different points in smoking progression.

Abstract
Genetic association studies using high-throughput genotyping and sequencing technologies have identified a large number of genetic variants associated with complex human diseases. These findings have provided an unprecedented opportunity to identify individuals in the population at high risk for disease who carry causal genetic mutations and hold great promise for early intervention and individualized medicine. While interest is high in building risk prediction models based on recent genetic findings, it is crucial to have appropriate statistical measurements to assess the performance of a genetic risk prediction model. Predictiveness curves were recently proposed as a graphic tool for evaluating a risk prediction model on the basis of a single continuous biomarker. The curve evaluates a risk prediction model for classification performance as well as its usefulness when applied to a population. In this article, we extend the predictiveness curve to measure the collective contribution of multiple genetic variants. We further propose a nonparametric, U-statistics-based measurement, referred to as the U-Index, to quantify the performance of a multi-locus predictiveness curve. In particular, a global U-Index and a partial U-Index can be used in the general population and a subpopulation of particular clinical interest, respectively. Through simulation studies, we demonstrate that the proposed U-Index has advantages over several existing summary statistics under various disease models. We also show that the partial U-Index can have its own uniqueness when rare variants have a substantial contribution to disease risk. Finally, we use the proposed predictiveness curve and its corresponding U-Index to evaluate the performance of a genetic risk prediction model for nicotine dependence.

Abstract
Combustible cigarettes remain the most harmful and addictive tobacco product, and reducing the prevalence of smoking continues to be a critical public health goal. While nicotine is the constituent primarily responsible for addiction to cigarettes, most of the harm associated with smoking comes from byproducts of tobacco combustion. Recently, two different approaches for reducing the harms of smoking have emerged, both of which focus on breaking the link between the addiction to nicotine and the harms caused by smoking. First, the addictive potential of cigarettes could be minimized by requiring a large reduction in the nicotine content of cigarettes. Evidence for a nicotine reduction policy thus far shows that the use of very low nicotine content cigarettes results in a reduction in the number of cigarettes people smoke per day and a reduction in cigarette dependence. Second, emerging alternative nicotine delivery systems (ANDS) like electronic cigarettes may provide sufficient nicotine to act as substitutes for cigarettes while delivering much lower levels of toxicants. Evidence suggests that the emergence of ANDS has increased the percentage of smokers who are able to quit. The present paper will briefly review the evidence for each of these approaches, and consider what contemporary reinforcement and addiction theories can tell us about their likely success. We argue that the most effective endgame approach is one that pursues both nicotine reduction and alternative nicotine delivery systems as complementary.

Abstract
BACKGROUND Alcohol and tobacco use are heritable phenotypes. However, only a small number of common genetic variants have been identified, and common variants account for a modest proportion of the heritability. Therefore, this study aims to investigate the role of low-frequency and rare variants in alcohol and tobacco use. METHODS We meta-analyzed ExomeChip association results from eight discovery cohorts and included 12,466 subjects and 7432 smokers in the analysis of alcohol consumption and tobacco use, respectively. The ExomeChip interrogates low-frequency and rare exonic variants, and in addition a small pool of common variants. We investigated top variants in an independent sample in which ICD-9 diagnoses of "alcoholism" (N = 25,508) and "tobacco use disorder" (N = 27,068) had been assessed. In addition to the single variant analysis, we performed gene-based, polygenic risk score (PRS), and pathway analyses. RESULTS The meta-analysis did not yield exome-wide significant results. When we jointly analyzed our top results with the independent sample, no low-frequency or rare variants reached significance for alcohol consumption or tobacco use. However, two common variants that were present on the ExomeChip, rs16969968 (p = 2.39 × 10-7) and rs8034191 (p = 6.31 × 10-7) located in CHRNA5 and AGPHD1 at 15q25.1, showed evidence for association with tobacco use. DISCUSSION Low-frequency and rare exonic variants with large effects do not play a major role in alcohol and tobacco use, nor does the aggregate effect of ExomeChip variants. However, our results confirmed the role of the CHRNA5-CHRNA3-CHRNB4 cluster of nicotinic acetylcholine receptor subunit genes in tobacco use.

Abstract
OBJECTIVES Adults who smoke increase their likelihood of death from smoking-exacerbated illnesses. The presence of illnesses exacerbated by smoking can be a powerful incentive to quit smoking. However, having a smoking-exacerbated illness does not stop all patients from smoking. Understanding that smoking may be a coping mechanism for stress, this study examined the association between the experiences of adverse events in childhood with continued smoking in adulthood among individuals and a smoking-exacerbated illness. STUDY DESIGN This retrospective observational study used 2014-2015 data from the South Carolina Behavioral Risk Factor Surveillance System survey. METHODS We used multivariable logistic regression to examine the impact of adverse childhood experience (ACE) exposure on current smoking status. RESULTS A total of 6321 respondents reported having a smoking-exacerbated illness. The most frequently reported categories of smoking-exacerbated illnesses were current asthma (63.9%), previous asthma (13.0%), and diabetes (12.3%). Overall, 62.4% of respondents had at least one ACE, with 20.3% of respondents having four or more ACEs. Respondents with one to three ACEs (adjusted odds ratio [aOR] 1.38; 95% confidence interval [CI] 1.37-1.40) and four or more ACEs (aOR 2.89; CI 2.86-2.92) were both significantly more likely to smoke than respondents with no ACEs, even in the presence of illnesses exacerbated by smoking. CONCLUSIONS Results suggest that ACE exposure may influence risky health behaviors in adulthood, such as continued smoking even in the presence of illnesses that are exacerbated by smoking. Given that smoking has been found to be a coping mechanism for adversity, anti-smoking efforts might benefit from designing interventions and treatment plans that address ACE exposure.

Abstract
Cigarette smoking is highly addictive and modern genetic research has identified robust genetic influences on nicotine dependence. An important step in translating these genetic findings to clinical practice is identifying the genetic factors affecting smoking cessation in order to enhance current smoking cessation treatments. We reviewed the significant genetic variants that predict nicotine dependence, smoking cessation, and response to cessation pharmacotherapy. These data suggest that genetic risks can predict smoking cessation outcomes and moderate the effect of pharmacological treatments. Some pharmacogenetic findings have been replicated in meta-analyses or in multiple smoking cessation trials. The variation in efficacy between smokers with different genetic markers supports the notion that personalized smoking cessation intervention based upon genotype could maximize the efficiency of such treatment while minimizing side effects, thus influencing the number needed to treat (NNT) and the number needed to harm. In summary, as precision medicine is revolutionizing healthcare, smoking cessation may be one of the first areas where genetic variants may identify individuals at increased risk. Current evidence strongly suggests that genetic variants predict cessation failure and that cessation pharmacotherapy effectiveness is modulated by biomarkers such as nicotinic cholinergic receptor α5 subunit (CHRNA5) genotypes or nicotine metabolism ratio (NMR). These findings strengthen the case for the development and rigorous testing of treatments that target patients with different biological risk profiles.

This study was aimed at assessing any association between smoking and health-related quality of life (HRQoL) among adults aged 18 years and above living in Kermanshah city, western Iran. A cross-sectional study was conducted on a total sample of 1,543 participants obtained by convenient sampling during the period from February 1st to May 30th, 2017. Data were collected using a self-administrated questionnaire. The HRQoL of the study participants was assessed with reference to the EuroQol 5-dimensions-3-level (EQ-5D-3L). The impact of smoking behavior of the participants on HRQoL with controls for potential confounders was examined by multiple regression. Out of the total of 1,543 participants, current smokers, past smokers, and never smokers accounted for 19.7%, 4.2% and 76.1%, respectively. The mean EQ-5D indices were 0.69 ±SD 0.20, 0.70 ± SD 0.22, and 0.78 ± SD 0.16. The highest proportion of self-reported problems (including both ‘some’ and ‘severe’) were related to current, heavy smokers, with high nicotine dependence. Regression analysis indicated that current smokers had a significantly lower HRQoL compared to past smokers and never smokers (p < 0.05). The heavy smokers also had a significantly lower HRQoL score than moderate and light smokers (p < 0.05) and there was an inverse relationship between the HRQoL score and nicotine dependence (p<0.05). The current smokers, heavy smokers, and high nicotine dependent smokers had lower HRQoL scores. These findings provide inputs for better understanding and for devising interventions for smoking cessation, reducing the number of cigarettes smoked per day and nicotine dependency.

Abstract
INTRODUCTION Waterpipe typically is smoked intermittently over long smoking sessions. Waterpipe is addictive and its users show symptoms of nicotine dependence (ND). This study examined the risk of developing ND symptoms across waterpipe use patterns among Lebanese youth. METHODS Waterpipe use patterns (length of smoking session, smoking a whole waterpipe without sharing, past-30day use frequency, number of waterpipes smoked) were assessed. Symptoms of ND were assessed using the 10-item Hooked on Nicotine Checklist (HONC; endorsement of ≥1 symptom) and the 6 criteria of the International Classification of Diseases-10th revision (ICD-10 ND; presence of ≥3 criteria during 12months). RESULTS Both the proportion of participants endorsing ND symptoms and the average number of endorsed ND symptoms increased with increasing waterpipe use frequency, number of waterpipes smoked, and length of smoking session. The risk of endorsing≥1 HONC symptom increased with increasing number of waterpipes smoked in the past 30-days (≥10 vs. <4 waterpipes; Hazard ratio (HR)=2.05, 95% CI: 1.52-2.58, p=0.007), and session length (>60min vs. <30min; HR=2.87, 95% CI: 2.83-2.91, p=0.001). The risk of attaining ICD-10 ND increased with increasing number of waterpipes used in the past 30-days (≥10 vs. <4 waterpipes; HR=2.56, 95% CI: 1.89-3.22, p=0.006), and smoking every day/almost every day vs. less than once weekly (HR=2.86, 95% CI: 2.12-3.60, p=0.007). CONCLUSIONS Increasing use frequency, number of waterpipes smoked, and longer smoking sessions were associated with higher risk of ND. The length of smoking session emerged as a novel indicator of ND among waterpipe smokers.

Abstract
BACKGROUND AND AIMS With no established standard for assessing tobacco dependence (TD) across tobacco products in surveys, the Population Assessment of Tobacco and Health (PATH) Study provides a unique platform for examining the psychometric properties and validity of multiple indicators of tobacco dependence across a range of tobacco products. PARTICIPANTS A U.S. nationally representative sample from the 32,320 adult Wave 1 interviews with analyses focused on 14,287 respondents who were current established users of tobacco products. FINDINGS This analysis confirms a single primary latent construct underlying responses to TD indicators for cigarettes, e-cigarettes, cigars, hookah, and smokeless tobacco products. Mutually exclusive past year tobacco-user groups included: cigarette only (n=8689), e-cigarette only (n=437), cigar only (traditional, cigarillo, or filtered) (n=706), hookah only (n=461), smokeless tobacco only (n=971), cigarette plus e-cigarette (n=709), and multiple tobacco product users (n=2314). Differential Item Functioning (DIF) analyses supported use of 16 of the 24 examined TD indicators for comparisons across tobacco users. With cigarette users as a reference (mean=0.0, SD=1.0), we observed a range of TD with hookah (mean=-1.71) and cigar (mean=-1.92) only users being the lowest, and cigarette plus e-cigarette product users being the highest (mean=0.35). Regression models including sociodemographic factors supported concurrent validity with increased product use frequency and TD among cigarette-only (p<0.001), e-cigarette only (p<0.002), cigar (p<0.001), hookah only (p<0.001), and smokeless tobacco users (p<0.001). CONCLUSION The PATH Study Adult Wave 1 Questionnaire provided psychometrically valid measures of TD that enables future regulatory investigations of nicotine dependence across tobacco products.

Significant association of the CHRNB3-CHRNA6 gene cluster with nicotine dependence in the Chinese Han population. Sci Rep 2017; 7:9745. [PMID: 28851948 PMCID: PMC5575130 DOI: 10.1038/s41598-017-09492-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2017] [Accepted: 07/25/2017] [Indexed: 11/08/2022] Open
Abstract
Although numerous studies have revealed significant associations between variants in the nicotinic acetylcholine receptors (nAChR) subunits and nicotine dependence (ND), only few studies were performed in Chinese subjects. Here, we performed association and interaction analysis for 20 single nucleotide polymorphisms (SNPs) in the CHRNB3-CHRNA6 gene cluster with ND in a Chinese Han population (N = 5,055). We found nominally significant associations for all tested SNPs with ND measured by the Fagerström Test for Nicotine Dependence score; of these, 11 SNPs remained significant after Bonferroni correction for multiple tests (p = 9 × 10−4~2 × 10−3). Further conditional analysis indicated that no other SNP was significantly associated with ND independent of the most-highly significant SNP, rs6474414. Also, our haplotype-based association analysis indicated that each haplotype block was significantly associated with ND (p < 0.01). Further, we provide the first evidence of the genetic interaction of these two genes in affecting ND in this sample with an empirical p-value of 0.0015. Finally, our meta-analysis of samples with Asian and European origins for five SNPs in CHRNB3 showed significant associations with ND, with p-values ranging from 6.86 × 10−14 for rs13280604 to 6.50 × 10−8 for rs4950. This represents the first study showing that CHRNB3/A6 are highly associated with ND in a large Chinese Han sample.

Abstract
Background Smoking cessation is the most powerful intervention to modify progress of chronic obstructive pulmonary disease (COPD), and nicotine dependence is one of the most important determinants of success or failure in smoking cessation. We evaluated nicotine dependence status and investigated factors associated with moderate to high nicotine dependence in patients with COPD. Methods We included 53 current smokers with COPD in the Korean Obstructive Lung Disease II cohort enrolled between January 2014 and March 2016. Nicotine dependence was measured by using Fagerstrom test for nicotine dependence (FTND). Cognitive function was assessed by Korean version of Montreal Cognitive Assessment. Results The median FTND score was 3, and 32 patients (60%) had moderate to high nicotine dependence. The median smoking amount was 44 pack-years, which was not related to nicotine dependence. Multiple logistic regression analysis revealed that high education status (odds ratio, 1.286; 95% confidence interval, 1.036–1.596; p=0.023), age <70 (odds ratio, 6.407; 95% confidence interval, 1.376–29.830; p=0.018), and mild to moderate airflow obstruction (odds ratio, 6.969; 95% confidence interval, 1.388–34.998; p=0.018) were related to moderate to high nicotine dependence. Conclusion Nicotine dependence does not correlate with smoking amount, but with education level, age, and severity of airflow obstruction. Physicians should provide different strategies of smoking cessation intervention for current smokers with COPD according to their education levels, age, and severity of airflow obstruction.

Abstract
Nicotine dependence (ND) has a reported heritability of 40-70%. Low-coverage whole-genome sequencing was conducted in 1,889 samples from the UCSF Family study. Linear mixed models were used to conduct genome-wide association (GWA) tests of ND in this and five cohorts obtained from the database of Genotypes and Phenotypes. Fixed-effect meta-analysis was carried out separately for European (n = 14,713) and African (n = 3,369) participants, and then in a combined analysis of both ancestral groups. The meta-analysis of African participants identified a significant and novel susceptibility signal (rs56247223; p = 4.11 × 10-8 ). Data from the Genotype-Tissue Expression (GTEx) study suggested the protective allele is associated with reduced mRNA expression of CACNA2D3 in three human brain tissues (p < 4.94 × 10-2 ). Sequence data from the UCSF Family study suggested that a rare nonsynonymous variant in this gene conferred increased risk for ND (p = 0.01) providing further support for CACNA2D3 involvement in ND. Suggestive associations were observed in six additional regions in both European and merged populations (p < 5.00 × 10-6 ). The top variants were found to regulate mRNA expression levels of genes in human brains using GTEx data (p < 0.05): HAX1 and CHRNB2 (rs1760803), ADAMTSL1 (rs17198023), PEX2 (rs12680810), GLIS3 (rs12348139), non-coding RNA for LINC00476 (rs10759883), and GABBR1 (rs56020557 and rs62392942). A gene-based association test further supported the relation between GABBR1 and ND (p = 6.36 × 10-7 ). These findings will inform the biological mechanisms and development of therapeutic targets for ND.

Abstract
INTRODUCTION We examined the stability of smoking behaviors, and factors associated with persistent smoking in a longitudinal study of HIV-positive gay and bisexual men in primary relationships. METHODS A sample of 377 HIV-positive men on antiretroviral therapy and their same-sex partners completed five assessments over two years. Participants completed semi-structured interviews which assessed smoking status, sociodemographic factors, relationship dynamics, and HIV-related disease characteristics. Latent transition analysis estimated the amount of transition in smoking over time. Latent class analysis examined factors associated with smoking status across the study period. RESULTS At baseline, 28.1% (n=106) of participants reported current smoking. Over 90% of the HIV-positive men remained in the same smoking category over time (68.4% persistent non-smokers; 24.1% persistent smokers). Men whose partners smoked and men with lower income had higher odds of being persistent smokers, whereas older men and men who identified as Latino race/ethnicity had lower odds of being persistent smokers compared to non-smokers. CONCLUSIONS Despite efforts to reduce smoking among people living with HIV (PLWH), a substantial subset of men continued to smoke during their two years in the study. Findings suggest that primary partners who also smoke and low income were the strongest predictors of sustained smoking behaviors among HIV-positive men. Additional research is needed to better understand how to increase motivation and support for smoking cessation among PLWH and their primary partners, while attending to how socioeconomic status may inhibit access to and the sustained impact of existing smoking cessation programs.

Abstract
Context: Successful tobacco quit by the tobacco users can avoid millions of premature death. However, the physical dependence on tobacco use results in frequent relapse most commonly due to withdrawal symptoms. Aims: The aim of this study was to study the level of tobacco dependence among tobacco users in an urban slum of Puducherry. Materials and Methods: This facility-based descriptive pilot study was conducted among patients aged 15 years or above attending an urban health and training center in an urban slum of Puducherry. A total of 90 consecutive current tobacco users were included after obtaining verbal informed consent and interviewed using a pretested questionnaire. The information on tobacco dependence was collected using Fagerstrom Addiction Scale for smokers and smokeless tobacco users separately. Results: Of the 90 current tobacco users, 95% were daily tobacco users. Of the current tobacco users, 48.8%, 45.6%, and 5.6% were smokers, smokeless tobacco users, and dual users, respectively. Majority of the smokers (61%) and most of the smokeless tobacco users (41%) had medium dependence for tobacco use. However, physical dependence was much higher among smokeless tobacco users (41.3%) than smokers (20.4%). Conclusion: Proportionately high physical dependence on tobacco is a concern in the study population. Community-based interventions are required to curb the problem; however, study with representative sample should be carried out before that.

Abstract
AIMS Although it is known that there is a high smoking prevalence among Chinese, key issues such as social and environmental factors impacting smoking initiation and persistence, the percentage of smokers considered nicotine dependence (ND), and the availability and use of ND treatments have rarely been investigated. METHODS To address these issues, from 2012 to 2014, we conducted a large-scale study in the Zhejiang and Shanxi provinces of China using the Fagerström Test for Nicotine Dependence and other validated questionnaires. RESULTS Of the 17,057 subjects, consisting of 13,476 males and 3,581 females aged 15 years or older, the prevalence of male smoking was 66.1% [95% confidence interval (CI) 65.5%, 66.9%] and that of female smoking was 3.2% (95% CI 3.0%, 3.8%). Among males, 25.8% (95% CI 25.0%, 26.5%) were low-to-moderate ND, and 11.8% (95% CI 11.2%, 12.3%) were high ND (H-ND), persons who have significant difficulty quitting without treatment. The degrees of ND were related to age, extent of education, and annual family income. The social-environmental factors examined conveyed a higher risk for smoking initiation, which is particularly true for the influence of smoking by friends. Furthermore, current smokers had a significantly higher risk of suffering respiratory and digestive symptoms. CONCLUSION These data not only show a high smoking prevalence in Chinese men but also reveal that a relatively large number of smokers are H-ND. Considering that few Chinese smokers seek ND treatment, a comprehensive smoking prevention and treatment program designed specifically for Chinese is greatly needed.

Abstract
This research sought to determine whether smoking influences affect by means other than withdrawal reduction. Little previous evidence suggests such an effect. We surmised that such an effect would be especially apparent in posttraumatic stress disorder (PTSD) and major depressive disorder (MDD), 2 disorders that are frequently comorbid with smoking and that involve dysregulated affect. Participants were U.S. veterans who were regular smokers (N = 159): 52 with PTSD (58% with comorbid MDD), 51 with MDD, and 56 controls with no psychiatric disorder. During 3 positive and 3 negative mood induction trials (scheduled over 2 sessions), nonwithdrawn participants smoked either a nicotine-containing cigarette (NIC+), a nicotine-free cigarette (NIC-), or held a pen. Positive and negative affect were each measured before and after mood induction. Results showed a significant 2-way interaction of Smoking Condition × Time on negative affect during the negative mood induction (F(6, 576) = 2.41, p = .03) in those with PTSD and controls. In these groups, both NIC+ and NIC-, relative to pen, produced lower negative affect ratings after the negative mood induction. There was also a 2-way interaction of Smoking Condition × Time on positive affect response to the positive mood induction among those with PTSD and controls (F(6, 564) = 3.17, p = .005) and among MDD and controls (F(6, 564) = 2.27, p = .036). Among all smokers, NIC+ enhanced the magnitude and duration of positive affect more than did NIC-. Results revealed affect modulation outside the context of withdrawal relief; such effects may motivate smoking among those with psychiatric diagnoses, and among smokers in general.

Abstract
BACKGROUND/AIM Exhaled CO level provides an objective measure of a patient's smoking status. The relationship between CO levels and nicotine dependence is controversial. The aim of this study is to evaluate the relationship between exhaled CO levels and nicotine dependence as well as to demonstrate that exhaled CO levels may be used as a marker of nicotine dependence. MATERIALS AND METHODS Two hundred eighty-nine patients (132 females, 157 males) were included in the study. Smoking duration, the age of smoking initiation, exhaled CO levels, and Fagerström Test for Nicotine Dependence (FTND) scores were recorded. The relationship between FTND scores and exhaled CO levels was investigated. RESULTS There was a statistically significant correlation between FTND score and exhaled CO levels (P < 0.001). We found that a cut-off score of 7.5 ppm for exhaled CO may be useful as a marker for heavy smoking. The sensitivity and specificity of this cut-off score for exhaled CO was 69.3% and 49.3%, respectively (P < 0.001). CONCLUSION We found that exhaled CO levels significantly correlated with FTND scores. For patients who are unable to provide reliable answers to questions in the FTND, exhaled CO measurements may be used as an alternative test for estimating the status of heavy smoking.

Abstract
BACKGROUND Cigarette smoking induces dopamine release in the striatum, and smoking- or nicotine-induced ventral striatal dopamine release is correlated with nicotine dependence. Smokers also exhibit lower dopamine D2/3 receptor availability in the dorsal striatum than nonsmokers. Negative correlations of striatal dopamine D2/3 receptor availability with smoking exposure and nicotine dependence, therefore, might be expected but have not been tested. METHODS Twenty smokers had positron emission tomography scans with [18F]fallypride to measure dopamine D2/3 receptor availability in ventral and dorsal regions of the striatum and provided self-report measures of recent and lifetime smoking and of nicotine dependence. RESULTS As reported before, lifetime smoking was correlated with nicotine dependence. New findings were that ventral striatal dopamine D2/3 receptor availability was negatively correlated with recent and lifetime smoking and also with nicotine dependence. CONCLUSION The results suggest an effect of smoking on ventral striatal D2/3 dopamine receptors that may contribute to nicotine dependence.

Abstract
Background Cigar and e-cigarette use is becoming increasingly common among US tobacco users and the Food and Drug Administration recently asserted regulatory jurisdiction over these products, among others, in May 2016. Research on tobacco dependence among users of these products is limited, however. We therefore examined several symptoms of dependence and cessation intentions among adult cigarette, cigar, and/or e-cigarette users in a nationally representative sample. Methods We used nationally representative data from more than 60,000 participants in the US National Adult Tobacco Survey (NATS) from 2012 to 2013 to analyze dependence symptoms and cessation intentions for users of cigarettes, cigars, and/or e-cigarettes but not other tobacco products. Results Among daily tobacco users, dual cigarette and cigar users on average smoked more cigarettes per day (17.3, 95 % CI = 16.1, 18.6 vs. 15.8, 95 % CI = 15.4, 16.2), had shorter times to first tobacco use after waking (21.4 min, 95 % CI = 16.6, 24.9 vs. 25.9 min, 95 % CI = 25.3, 26.5), and were more likely to report withdrawal and craving symptoms than exclusive cigarette smokers. Dual cigarette and e-cigarette users were more likely than exclusive cigarette smokers to report withdrawal and craving symptoms and cessation intentions. Exclusive cigar and e-cigarette users were less likely to report withdrawal and craving symptoms than users of other products, but even so, more than a third of exclusive cigar (38.8 %, 95 % CI = 27.4 %, 51.6 %) and e-cigarette (46.1 %, 95 % CI = 35.1 %, 57.4 %) users reported experiencing a strong craving for a tobacco product in the past 30 days. Conclusions Dual cigarette and cigar users show evidence of greater dependence symptoms and dual cigarette and e-cigarette users show evidence of greater dependence symptoms and cessation intentions compared with exclusive cigarette smokers. A sizeable number of users of all of the tobacco products report dependence symptoms such as craving for tobacco.

Abstract
Little is known of smoking trajectories or of the correlates of smoking trajectories among African American youth. Ninth-grade African American adolescents (n = 566) were interviewed in Year 1 and then were subsequently interviewed annually for 3 additional years. Five trajectories of cigarette smokers were identified: abstainers, experimenters/consistent light smokers, consistent regular smokers, accelerators, and quitters. Psychological well-being at Year 1 was lower among consistent regular smokers and accelerators as compared to abstainers. Variance in other problem behaviors mirrored the smoker trajectories. At Year 4,the abstainers and experimenters/consistent light smokers reported greater participation in sports activities as compared to the quitters, whereas the abstainers reported greater participation in other school activities as compared to the consistent regular smokers.

Abstract
As the risks of tobacco use become recognized and smoking becomes stigmatized, new smokers may be increasingly driven to smoke by biological or genetic vulnerabilities rather than social desirability. Given that genetic risk for deviant proneness is shared across other psychiatric and addictive disorders, we predicted that as rates of smoking decreased through the latter half of the twentieth century, associations between smoking and psychopathology would increase. Participants (N=25 412) from a large US study-the National Epidemiologic Survey on Alcohol and Related Conditions, NESARC-were interviewed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule - DSM-IV Version (AUDADIS-IV) and classified into one of five birth cohort decades (1940s to 1980s) and three smoking history (nonsmokers, never-dependent smokers and ever-dependent smokers) groups. We found that the prevalence of smoking decreased across the five birth cohorts, but associations of smoking with drug and AUDs, attention-deficit hyperactivity disorder, bipolar disorder and antisocial personality disorder, each increased monotonically in more recently born cohorts, even after adjusting for concurrent demographic and socioeconomic changes. For drug and AUDs, increases were observed among smokers both with and without a history of nicotine dependence; for other outcomes, increases were entirely driven by nicotine-dependent smokers. Findings suggest that smokers in more recent cohorts have disproportionately high psychiatric vulnerability, and may benefit from greater mental health screenings. Differentiating between casual and dependent smokers may further help prioritize those at greatest risk. Researchers should also be aware of potential variation in psychiatric comorbidity based on cohort of birth when defining groups of smokers, to minimize confounding.

Abstract
Empirical evidence has identified several risk factors for panic psychopathology, including smoking and anxiety sensitivity (AS; the fear of anxiety-related sensations). Smokers with elevated AS are therefore a particularly vulnerable population for panic. Yet, there is little knowledge about how to reduce risk of panic among high AS smokers. The present study prospectively evaluated panic outcomes within the context of a controlled randomized risk reduction program for smokers. Participants (N = 526) included current smokers who all received a state-of-the-art smoking cessation intervention with approximately half randomized to the AS reduction intervention termed Panic-smoking Program (PSP). The primary hypotheses focus on examining the effects of a PSP on panic symptoms in the context of this vulnerable population. Consistent with prediction, there was a significant effect of treatment condition on AS, such that individuals in the PSP condition, compared to those in the control condition, demonstrated greater decreases in AS throughout treatment and the follow-up period. In addition, PSP treatment resulted in lower rates of panic-related symptomatology. Moreover, mediation analyses indicated that reductions in AS resulted in lower panic symptoms. The present study provides the first empirical evidence that brief, targeted psychoeducational interventions can mitigate panic risk among smokers.

Abstract
Background Depression and anxiety are correlated with greater nicotine dependence, smoking persistence, and relapse back to smoking after a quit attempt. Menthol cigarette smoking, which is prevalent in young adults, is associated with nicotine dependence, progression to regular smoking, and worse cessation outcomes than non-menthol smoking. Few have established a link between menthol tobacco use, beyond just smoking, with mental health in this high-risk age group. This study examined the association of menthol tobacco use to anxiety and depression in a national sample of young adults. Methods Data were from Waves 1 through 7 (n = 9720, weighted) of the Truth Initiative Young Adult Cohort, a national sample of men and women aged 18 to 34 assessed every 6-months. Demographics, past 30-day use of non-menthol and menthol tobacco products, and current alcohol, marijuana, and other drug use were assessed among those with depression and anxiety. Results Thirty nine percent of current tobacco users used menthol as their preferred brand. Using a cross-sectional analysis (collapsed across waves), past 30-day menthol tobacco was uniquely associated with greater odds of both depression and anxiety, beyond the effects of demographic and substance correlates and non-menthol tobacco product use. Conclusions Menthol is disproportionately used among young adults tobacco users with mental health problems, above and beyond the impact of a variety of other mental health and tobacco use risk factors. Findings suggest a strong link between menthol tobacco use and poor health outcomes. Policies should be developed to deter menthol tobacco use in vulnerable groups.
