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 Measures designed to assess electronic cigarette (ECIG) dependence are largely adapted from those developed for cigarette smoking, and have been evaluated mainly among dual ECIG-cigarette users. The present study evaluated the psychometric properties of four dependence measures among former-smoking ECIG users. METHODS Respondents (N = 187) were daily ECIG users who had formerly smoked cigarettes regularly. As part of an online survey, they completed four dependence measures: Penn State Electronic Cigarette Dependence Index (PSECDI); E-Cigarette Dependence Scale (EDS-4); Glover Nilsson Behavioral Questionnaire (GNBQ); and Diagnostic and Statistical Manual 5th Edition (DSM-5). RESULTS Confirmatory factor analysis revealed a single factor structure for all four measures, and fit indices were adequate for all models. Most inter-item correlations (mean r's = 0.21 to 0.45) and all item-total correlations (mean r's = 0.53 to 0.80) were significant for all four measures. Internal consistency was highest for the GNBQ (α = 0.86) followed by the EDS-4 (α = 0.81), PSECDI (α = 0.76), and DSM-5 (α = 0.75). Age of ECIG initiation was correlated negatively with scores on the EDS-4 and DSM-5, while number of ECIG quit attempts was correlated positively with scores on all measures except the GNBQ. Convergent validity was highest for comparisons between the EDS-4 and PSECDI (r = 0.75) though all comparisons were significant (p's < 0.001). CONCLUSIONS All four measures demonstrated acceptable reliability and validity in this sample of former-smoking ECIG users.

Abstract
BACKGROUND Nicotine replacement therapy (NRT) and short messaging service (SMS)-based tobacco cessation interventions have demonstrated effectiveness in reducing tobacco use in many populations, but evidence is needed on which tailored treatments are most efficacious in meeting the complex medical and psychosocial factors confronting people living with HIV (PLWH) in sub-Saharan Africa (SSA). This paper describes the protocol of a study to test the efficacy of both NRT and a tailored SMS-based tobacco use cessation intervention among PLWH in Uganda and Zambia. METHODS In a randomized controlled trial, 800 adult PLWH who use tobacco will be recruited by health care professionals at HIV treatment centers where they are receiving care. Participants will be randomized to one of the four study arms: (1) standard of care [SOC; brief clinician advice to quit combined with HIV education and information aimed at encouraging HIV treatment adherence (with no mention of tobacco) delivered via text messages]; (2) SOC + 12 weeks of NRT; (3) SOC + 6 weeks of SMS text messages to support quitting tobacco use (SMS); or (4) SOC + NRT + SMS. Participants will receive a cell phone and solar panel with power bank for charging the phone. The main outcome is cessation of tobacco use by study participants verified by urinary cotinine (< 15 ng/mL) at 6 months post-enrollment. As a secondary tobacco use outcome, we will measure 7-day point-prevalence abstinence (7 consecutive days of no tobacco use) measured by self-report and biochemically-verified at 4 weeks, 8 weeks, and 3 months post enrollment. DISCUSSION Our study will provide insight into the efficacy, feasibility and applicability of delivering tobacco cessation interventions through health care professionals combined with tailored tobacco cessation SMS text messaging in two countries with different tobacco use patterns, policy environments, and health care resources and provide needed information to providers and policymakers looking for cost-effective tobacco cessation interventions. The previously tested SMS-platform to be used in our study is uniquely positioned to be scaled in low- and middle-income countries worldwide, in which case evidence of even modest success in reducing the prevalence of tobacco consumption among PLWH could confer enormous health and economic benefits.

Abstract
Cigarette smoking is the world's leading cause of preventable death and disease. Alternative nicotine products such as e-cigarettes have tobacco harm reduction potential, by providing smokers with an alternative form of nicotine delivery but with either the reduced presence or absence of the numerous harmful chemicals found in combustible cigarette smoke. One aspect of importance in determining the potential of e-cigarettes to provide a viable alternative to combustible cigarettes for smokers is their ability to cause dependence, also known as their abuse liability. E-cigarettes with little or no abuse liability would be unlikely to be used as a substitute for cigarettes, whereas at least some degree of abuse liability is acknowledged as supportive both to aiding cigarette substitution or complete cessation and to preventing relapse. Given this link between abuse liability and substitution efficacy, human studies assessing the abuse liability of e-cigarettes are important to determine their true harm reduction potential. In this review, the concept of tobacco product abuse liability is discussed, along with the primary elements-pharmacokinetics and pharmacodynamics (subjective effects)-that need to be assessed to determine abuse liability. The review also presents a number of human abuse liability study design considerations and discusses what existing studies in the literature tell us about the abuse liability and harm reduction potential of e-cigarettes.

Abstract
INTRODUCTION Extant electronic cigarette (ECIG) dependence measures are largely adapted from those designed for cigarette smoking, though few have been evaluated for their psychometric properties. AIMS AND METHODS Never-smoking ECIG users (N = 134) participating in an online survey completed four dependence measures: Penn state electronic cigarette dependence index (PSECDI), e-cigarette dependence scale (EDS-4), diagnostic and statistical manual for tobacco use disorder (DSM-5), and Glover Nilsson behavioral questionnaire (GNBQ). They also reported on their ECIG use characteristics (eg, behaviors and reasons). RESULTS Internal consistency was highest for the EDS-4 (Cronbach's α = 0.88) followed by the GNBQ (α = 0.75), PSECDI (α = 0.72), and DSM (α = 0.71). Confirmatory factor analyses revealed a single-factor structure for the PSECDI, EDS-4, and GNBQ. For the DSM-5, however, two items did not load significantly (ECIG use interferes with responsibilities; reduce/give up activities because of ECIG use). Significant correlations were observed between all measures and the number of ECIG use days/week and/or years using ECIGs, as well as between DSM-5 scores and the number of ECIG quit attempts and initiation age. Endorsement of using ECIGs because "I like flavors" was correlated positively with DSM-5 and GNBQ scores. CONCLUSIONS All dependence measures evaluated herein demonstrated adequate reliability and construct validity. Future work should focus on determining which aspects of dependence are those that are unique to ECIG use, and subsequently developing a more comprehensive measure of ECIG dependence. IMPLICATIONS The measures assessed herein-PSECDI, EDS-4, DSM-5, and GNBQ-demonstrated adequate to good reliability and construct validity among a sample of never-smoking ECIG users. The dependence domains covered across measures were related yet distinct. Findings demonstrate the need for future evaluation of these different domains to determine which are the most salient characteristics of ECIG dependence.

Abstract
INTRODUCTION Khaini is a smokeless tobacco (SLT) product commonly used in the South-Asian region. It is the most common smokeless tobacco product used in India, having a prevalence of 11.2% and is used by 104.1 million adults. No scales exist to assess khaini dependence. Existing scales available to assess dependence on smokeless tobacco products are not ideal as these are adapted from cigarette dependence scales and developed for western populations. This study aimed to develop a khaini dependence scale and assess its reliability and validity. METHODS Recommended methods for scale development were followed for item development, scale development and scale evaluation. Scale development was guided by a theoretical framework, a review of existing scales and in-depth interviews with 21 khaini users recruited from a tertiary care hospital in Mumbai, India. The process involved the identification of domains for dependence and the development of an item pool. Cognitive interviews and pre-testing were conducted with 20 khaini users to assess content validity. A cross-sectional survey with 323 khaini users was conducted, and Exploratory Factor Analysis (EFA) was used to determine the factor structure of the draft scale. The content validity, criterion validity (by cross-referencing with the cotinine level of users), convergent validity and internal consistency of the new scale were assessed. RESULTS The final version of the Khaini SLT Dependence Scale (KSLTDS) had 20 items. EFA indicated an acceptable goodness of fit for a three-factor structure with physical, psychological and sociocultural-behavioral sub-scales. It showed evidence of acceptable criterion validity with cotinine (ρ=0.43, p=0.0002), convergent validity with FTND-ST (ρ=0.51, p<0.0001) and frequency of khaini use (ρ=0.38, p<0.0001). The sub-scales (α=0.87-0.90) showed acceptable internal consistency. CONCLUSIONS The psychometric evaluation of the KSLTDS showed preliminary validity and reliability for assessing dependence on khaini, and therefore, it is appropriate for clinical and research purposes. Re-validation studies are required with various khaini user populations.

An abuse liability assessment of the glo tobacco heating product in comparison to combustible cigarettes and nicotine replacement therapy. Sci Rep 2022; 12:14701.

Abstract
Tobacco heating products (THPs) have reduced emissions of toxicants compared with cigarette smoke, and as they expose user to lower levels than smoking, have for a role to play in tobacco harm reduction. One key concern of Public Health is that new tobacco and nicotine products should not be more addictive than cigarettes. To assess their abuse liability, we determined nicotine pharmacokinetics and subjective effects of two THPs compared with conventional cigarettes and a nicotine replacement therapy (Nicotine inhaler). In a randomised, controlled, open-label, crossover study healthy adult smokers used a different study product in a 5 min ad libitum use session in each of four study periods. Product liking, overall intent to use again, urge for product and urge to smoke questionnaires were utilised to assess subjective effects. Nicotine uptake was greater for the cigarette (Cmax = 22.7 ng/mL) than for either THP (8.6 and 10.5 ng/mL) and the NRT (2.3 ng/mL). Median Tmax was significantly longer for the NRT (15.03 min) than for the tobacco products (4.05–6.03 min). Product liking and overall intent to use again was highest for the cigarette, and higher for the THPs than the NRT. Urge to smoke was reduced more by the cigarette than by the other three products. Urge to use the THPs was greater than the NRT. These findings suggest that the abuse liability of the THPs lies between that of subjects usual brand cigarettes and the NRT.

Abstract
BACKGROUND Due to the increasing use of alternative tobacco products (waterpipes, heat-not-burn) and tobacco alternatives (e-cigarettes), we studied recent changes in the prevalence of conventional tobacco use and alternative products. METHODS Data come from ten waves of the Epidemiological Survey of Substance Abuse (ESA) from 1995 to 2021, with representative samples collected via paperpencil questionnaires, telephone interviews, or online. We compared the prevalence of conventional tobacco use and alternative products by gender and age (18-24, 25-39, 40-59 years). RESULTS In all age groups, the use of conventional tobacco products decreased. The prevalence of the exclusive use of one of the three alternative products differed statistically significantly between age groups and in 2021 was higher for ages 18-24 (females: 11.1%, males: 12.4%) compared to ages 25-39 (females: 2.9%; males: 4.9%) and ages 40-59 (females: 1.4%; males: 2.0%). The use of alternative products was mainly due to the exclusive use of waterpipes among individuals aged 18 to 24 and 25 to 39 and the exclusive use of e-cigarettes among individuals aged 40 to 59. CONCLUSION The higher prevalence of alternative product use among young adults implies a turning point that needs to be considered in prevention. Because of the addictive potential of these products, young adults can be expected to maintain their use into middle and older adulthood. There is a need to monitor the use of alternative products, identify the risks associated with them, and develop effective prevention and cessation interventions for adults.

Abstract
OBJECTIVES To detect the cotinine and nicotine serum concentrations of female and male C57BL/6J mice after a 4-week exposure to electronic (e)-cigarette vapors using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). METHODS This experimental study was carried out at an animal facility and laboratories, College of Pharmacy, King Saud University, Riyadh, Saudi Arabia, between January and August 2020. A 4-week exposure to e-cigarettes was carried out using male and female mice and serum samples were obtained for cotinine and nicotine quantification using UPLC-MS/MS. The chromatographic procedures involved the use of a BEH HSS T3 C18 column (100 mm x 2.1 mm, 1.7 μm) with acetonitrile as a mobile phase and 0.1% formic acid (2:98 v/v). RESULTS The applied methodology has highly efficient properties of detection, estimation, and extraction, where the limit of quantification (LOQ) for nicotine was 0.57 ng/mL and limit of detection (LOD) for nicotine was 0.19 ng/mL, while the LOQ for cotinine was 1.11 ng/mL and LOD for cotinine was 0.38 ng/mL. The correlation coefficient was r2>0.99 for both compounds. The average recovery rate was 101.6±1.33 for nicotine and 100.4±0.54 for cotinine, while the precision and accuracy for cotinine and nicotine were less than 6.1. The serum cotinine level was higher in males (433.7±19.55) than females (362.3±16.27). CONCLUSION This study showed that the gender factor might play a crucial role in nicotine metabolism.

Abstract
BACKGROUND The use of smokeless tobacco has increased worldwide among young people. This study aimed to investigate the association between smokeless tobacco use and cigarette smoking amount in adult smoker groups stratified by age. METHOD 2013-2015 National Health Interview Survey was used. A total of 19,635 subjects were included in our analysis. Propensity score matching was used to adjust for selection and any other bias. Generalized estimating equation was used to analyze the association between smokeless tobacco use and cigarette smoking amount by age. RESULTS All 580 smokeless tobacco users were matched to 2,900 non-smokeless tobacco users. Among those who were aged under 30, smokeless tobacco use was positively associated with the number of cigarettes used per day. Smokeless tobacco users who were aged under 30 and tried quitting smoking used more cigarettes than those who did non-smokeless tobacco users. CONCLUSIONS The present study revealed that among those who were aged under 30, smokeless tobacco use was positively associated with the number of cigarettes used per day. This study could contribute to understand the behaviors and tendencies of smoking in young adulthood and to establish effective smoking cessation methods for their age.

Validation of the Wave 1 and Wave 2 Population Assessment of Tobacco and Health (PATH) Study Indicators of Tobacco Dependence Using Biomarkers of Nicotine Exposure Across Tobacco Products.

Abstract
INTRODUCTION This study examined the predictive relationships between biomarkers of nicotine exposure and 16-item self-reported level of tobacco dependence (TD) and subsequent tobacco use outcomes. AIMS AND METHODS The Population Assessment of Tobacco and Health (PATH) Study surveyed adult current established tobacco users who provided urine biospecimens at Wave 1 (September 2013-December 2014) and completed the Wave 2 (October 2014-October 2015) interview (n = 6872). Mutually exclusive user groups at Wave 1 included: Cigarette Only, E-cigarette Only, Cigar Only, Hookah Only, Smokeless Tobacco Only, Cigarette Plus E-cigarette, multiple tobacco product users who smoked cigarettes, and multiple tobacco product users who did not smoke cigarettes. Total Nicotine Equivalents (TNE-2) and TD were measured at Wave 1. Approximate one-year outcomes included frequency/quantity used, quitting, and adding/switching to different tobacco products. RESULTS For Cigarette Only smokers and multiple tobacco product users who smoked cigarettes, higher TD and TNE-2 were associated with: a tendency to smoke more, smoking more frequently over time, decreased likelihood of switching away from cigarettes, and decreased probability of quitting after one year. For other product user groups, Wave 1 TD and/or TNE-2 were less consistently related to changes in quantity and frequency of product use, or for adding or switching products, but higher TNE-2 was more consistently predictive of decreased probability of quitting. CONCLUSIONS Self-reported TD and nicotine exposure assess common and independent aspects of dependence in relation to tobacco use behaviors for cigarette smokers. For other product user groups, nicotine exposure is a more consistent predictor of quitting than self-reported TD. IMPLICATIONS This study suggests that smoking cigarettes leads to the most coherent pattern of associations consistent with a syndrome of TD. Because cigarettes continue to be prevalent and harmful, efforts to decrease their use may be accelerated via conventional means (eg, smoking cessation interventions and treatments), but also perhaps by decreasing their dependence potential. The implications for noncombustible tobacco products are less clear as the stability of tobacco use patterns that include products such as e-cigarettes continue to evolve. TD, nicotine exposure measures, and consumption could be used in studies that attempt to understand and predict product-specific tobacco use behavioral outcomes.

Impact of a soft tip nicotine-free harmless cigarette as part of a smoking cessation program with psychological support and varenicline: an integrated workplace smoking cessation intervention. Health Psychol Res 2021; 9:24506.

Abstract
Cigarette consumption in the general population has shown a sustained decline over the past 20 years, but despite this, it is essential to monitor consumption among smokers at their workplace. There is an association between cigarette addiction and work-related stressors, with high prevalence rates for smokers, at least double those of other adults. This two-group randomized clinical trial compared the 12-week combined effect of psychological support and varenicline associated with the use or not of a nicotine-free inhaler with a soft mouthpiece (QuitGo™) on the 4 to 24-week cessation rate in enrolled smokers to a smoking cessation program promoted by our research group. The results of the logistic model analysis showed that the likelihood of quitting successfully at week 24 was significantly higher in the QuitGO™ group than in the control group for participants with high behavioral dependence as assessed by Glover-Nilsson Smoking Behavioral Questionnaire-GN-SBQ (OR = 8.55; CI at 95% = 1.75-43.20). The data presented suggest that the soft tip nicotine-free harmless cigarette may be helpful for smokers and those with work-related stress symptoms who recognize the need to have a gesture in the traditional cigarette smoking ritual.

Abstract
BACKGROUND AND AIM There have been substantial recent changes in youth tobacco product use in the United States-including, notably, a rapid increase in use of e-cigarettes. It is not known whether, and if so how far, these changes are reflected in levels of nicotine dependence. This study used data from a large, nationally representative sample of US adolescents to (i) estimate the annual prevalence of nicotine dependence in relation to current use of tobacco products, (ii) describe trends in dependence over time and (iii) evaluate whether the increase in youth use of tobacco products has been paralleled by a similar increase in the population burden of nicotine dependence. DESIGN Secondary analysis of National Youth Tobacco Surveys conducted annually, 2012-19. SETTING United States. PARTICIPANTS A total of 86 902 high school students. MEASUREMENTS Prevalence of (i) strong cravings to use tobacco in the past 30 days and (ii) wanting to use nicotine products within 30 minutes of waking, in relation to type of product used (cigarettes, other combustible tobacco, smokeless tobacco, e-cigarettes). FINDINGS Between 2012 and 2019 there was a marked decline in past 30-day cigarette smoking and a surge in use of e-cigarettes. Different products were associated with differing levels of nicotine dependence, with cigarettes characterized by highest dependence (strong craving 42.3%; wanting to use within 30 minutes 16.8% among exclusive users in 2019) and e-cigarettes in otherwise tobacco-naive students by low dependence (16.1 and 8.8% respectively in 2019). The overall 33.8% increase in population use of nicotine products between 2012 and 2019 (from 23.2 to 31.2%) was not accompanied by an equivalent increase in overall population burden of dependence {percentage reporting craving 10.9% [95% confidence interval (CI) = 9.8-12.2%] in 2012 and 9.5% (95% CI = 7.5-12.0%) in 2019; wanting to use within 30 minutes 4.7% (95% CI = 4.0-5.5%) in 2012, 5.4% (95% CI = 4.0-7.2%) in 2019}. CONCLUSIONS Among US high school students, increases in the prevalence of nicotine product use from 2012 to 2019 do not appear to have been accompanied by a similar increase in the population burden of nicotine dependence. This may be at least partly attributable to a shift in the most common product of choice from cigarettes (on which users are most dependent) to e-cigarettes (on which users are least dependent).

Abstract
INTRODUCTION Research is needed to examine trajectories of tobacco use beyond cigarette smoking, particularly during emerging middle young adulthood, and to identify distinct multilevel influences of use trajectories. AIMS AND METHODS We examined (1) tobacco use trajectories over a 2-year period among 2592 young adult college students in a longitudinal cohort study and (2) predictors of these trajectories using variables from a socioecological framework, including intrapersonal-level factors (eg, sociodemographics, psychosocial factors [eg, adverse childhood experiences, depressive symptoms, and attention-deficit hyperactivity disorder symptoms], early-onset substance use), interpersonal factors (eg, social support, parental substance use), and community-level factors (eg, college type, rural vs. urban). RESULTS About 64.5% were female and 65.0% were white. From age 18 to 26, 27%-31% of participants reported past 30-day use of any tobacco product. We identified four trajectory classes: Abstainers/Dabblers who never or infrequently used (89.2%); Adult users who began using frequently around age 20 and continued thereafter (5.9%); College Smokers who began using before 19 but ceased use around 25 (2.5%); and Teenage users who used during their teenage years but ceased use by 22 (1.9%). Multinomial regression showed that, compared to Abstainers/Dabblers, significant predictors (p < .05) of being (1) Adult users included being male, earlier onset marijuana use, attending public universities or technical colleges (vs. private universities), and living in urban areas; (2) College users included being male, earlier onset marijuana use, and parental alcohol or marijuana use; and (3) Teenage users included only earlier onset marijuana use. CONCLUSION Distinct prevention and intervention efforts may be needed to address the trajectories identified. IMPLICATIONS Among young adult college students, the largest proportion of tobacco users demonstrate the risk of continued and/or progression of tobacco use beyond college. In addition, specific factors, particularly sex, earlier onset marijuana use, parental use of alcohol and marijuana, and contextual factors such as college setting (type of school, rural vs. urban) may influence tobacco use outcomes. As such, prevention and cessation intervention strategies are needed to address multilevel influences.

Abstract
Background Studies of the patterns of polytobacco use have increased. However, understanding the patterns of using multiple tobacco products among Black adolescents is minimal. This study identified the patterns of polytobacco use among U.S. Black adolescents. Methods Latent class analysis (LCA) was used to identify patterns of adolescent polytobacco use among a representative sample of Black youth from the 2017 Youth Risk Behavior Survey (n = 2782). Ever and recent (past 30 day) use of cigarettes, electronic cigarettes, cigars, and dip or chewing tobacco were used as latent class indicators. Multinomial regression was conducted to identify the association if smoking adjusting for sex, age, grade, and marijuana use. Results Most students were in the 9th grade (29%), e-cigarette users (21%) and were current marijuana users (25%). Three profiles of tobacco use were identified: Class 1: Non-smokers (81%), Class 2: E-cigarette Users (14%), and Class 3: Polytobacco Users (5%). Black adolescent Polytobacco users were the smallest class, but had the highest conditional probabilities of recent cigarette use, e-cigarette use, ever smoking cigars or chewing tobacco. Ever and current use of marijuana were associated with increased odds of being in the e-cigarette user versus non-smoker group, and current marijuana use was associated with increased odds of polytobacco use (aOR = 24.61, CI = 6.95–87.11). Conclusions Findings suggests the need for targeted interventions for reducing tobacco use and examining the unique effects of polytobacco use on Black adolescents. Findings confirm a significant association of marijuana use with tobacco use.

Abuse liability assessment of the JUUL system in two nicotine concentrations compared to combustible cigarette, nicotine gum and comparator electronic nicotine delivery system. Drug Alcohol Depend 2020; 217:108441.

Abstract
BACKGROUND To assess the abuse liability of the JUUL System (JS) in 5.0 % (59 mg/mL) and 3.0 % (35 mg/mL) nicotine concentrations. METHODS Adult smokers (N = 146; 45.9 % female; mean age = 41.29 years) were randomized to one of four study flavor arms and then to a within-subjects cross-over sequence for five test product categories: (1) JS 5.0 % nicotine concentration; (2) JS 3.0 % nicotine; (3) usual brand (UB) cigarette; (4) 4 mg mint nicotine gum; (5) comparator ENDS (VUSE Alto 5.0 % nicotine). Products were tested by ad libitum use (5 min for ENDS and cigarette; 30 min for gum); nicotine pharmacokinetic (PK) parameters and subjective effects were assessed following use. RESULTS Maximum plasma nicotine concentration (Cmax-BL), rate of plasma nicotine rise and total nicotine exposure (AUC0-60-BL) of UB cigarette were significantly greater than all other test products. The comparator ENDS was significantly greater than 5.0 % and 3.0 % JS and nicotine gum on Cmax-BL, rate of plasma nicotine rise, and AUC0-60-BL; Cmax-BL of JS 5.0 % was significantly greater than JS 3.0 % and nicotine gum. Product liking and satisfying effects were significantly highest for the UB cigarette; JS products and comparator ENDS did not significantly differ and were rated higher than nicotine gum on most subjective measures. CONCLUSIONS These results suggest that the abuse liability of both 5.0 % and 3.0 % JS is: (1) substantially lower than UB cigarette; (2) somewhat lower than comparator ENDS; and (3) higher than nicotine gum. Additionally, the abuse liability of JS 5.0 % is somewhat higher than JS 3.0 %.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2020; 88:103020. [PMID: 33161296 DOI: 10.1016/j.drugpo.2020.103020] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2020] [Revised: 10/18/2020] [Accepted: 10/22/2020] [Indexed: 01/09/2023]
Abstract
BACKGROUND Cleaner nicotine delivery devices, such as nicotine vaping products (NVPs), could expose smokers to less harm than combustible cigarettes. While use of NVPs is increasing, it is unknown how harm reduction attitudes are related to intention to use these or other "clean nicotine" products and how smokers would prefer to use them. METHODS A sample of 1,538 Australian smokers participated in an online survey. Questions covered use NVPs and nicotine replacement therapy (NRT), and attitudes towards a hypothetical "clean nicotine" product and tobacco harm reduction. RESULTS Lifetime use of NVPs was reported by 21% of participants, while 42% reported that they would probably or definitely use NVPs as a cessation aid in the future. Around three-quarters expressed interest in using a hypothetical clean nicotine product as a short-term cessation aid (75.7%), a long-term substitute for cigarettes (72.4%), or as a partial replacement for cigarettes (74.9%). However, despite this interest, 52% endorsed the statement that using nicotine products long-term was undesirable because it maintained nicotine addiction. A binary logistic regression showed that interest in using the hypothetical "clean nicotine" product was associated with higher education, moderate nicotine dependence, support of tobacco harm reduction, and previous use of NRT and NVPs. CONCLUSION Most smokers were interested in the use of a hypothetical clean nicotine product that is as addictive as combustible cigarettes but much less harmful. However, many of the participants who were interested in the use of a hypothetical clean nicotine product also endorsed statements that long-term addiction to nicotine is undesirable. These seemingly contradictory findings have implications for communication with smokers about tobacco harm reduction approaches with non-smoked nicotine products.

Abstract
Background Most hookah use studies have not included racial and ethnic minorities which limits our understanding of its use among these growing populations. This study aimed to investigate the individual characteristics of hookah use patterns and associated risk behaviors among an ethnically diverse sample of college students. Methods A cross-sectional survey of 2460 students (aged 18–25) was conducted in 2015, and data was analyzed in 2017. Descriptive statistics were used to present the sociodemographic characteristics, hookah use-related behavior, and binge drinking and marijuana use according to the current hookah use group, including never, exclusive, dual/poly hookah use. Multivariate logistic regression was conducted to examine how hookah related behavior and other risk behaviors varied by sociodemographics and hookah use patterns. Results Among current hookah users (n = 312), 70% were exclusive hookah users and 30% were dual/poly hookah users. There were no statistically significant differences in sociodemographic characteristics except for race/ethnicity (p < 0.05). Almost half (44%) of the exclusive hookah users reported having at least five friends who also used hookah, compared to 30% in the dual/poly use group. Exclusive users were less likely to report past year binge drinking (17%) and past year marijuana use (25%) compared to those in the dual/poly use group (44 and 48% respectively); p < 0.001. Conclusions The socialization aspects of hookah smoking seem to be associated with its use patterns. Our study calls for multicomponent interventions designed to target poly tobacco use as well as other substance use that appears to be relatively common among hookah users.

Abstract
INTRODUCTION Polytobacco use is a growing concern; users are exposed to cumulatively more nicotine, increasing their risk for dependence and long-term use. More sexual minority (SM) young adults report polytobacco use than their heterosexual peers, yet no studies explore how their tobacco patterns vary across the diverse product landscape. The purpose of this study was to characterize SM young adults' patterns of tobacco use and nicotine dependence, and explore co-occurring risk factors for polytobacco use. METHODS Participants were 609 SM Texas college students. Latent class analysis identified subgroups of tobacco users based on their tobacco use behaviors and an indicator of nicotine dependence. Multinomial logistic regression identified associations between individual-level variables and the probability of membership in various user classes. RESULTS Tobacco use clustered in four classes: non-users, non-addicted cigarette users, non-addicted e-cigarette users, and addicted polytobacco users. Polytobacco users had an increased probability of depressive symptoms and cannabis use relative to non-users, and more binge alcohol use than all other groups. Non-addicted cigarette users had an increased probability of binge alcohol use, cannabis use, and being non-Hispanic White relative to non-users, and an increased likelihood of cannabis use relative to non-addicted e-cigarette users. Non-addicted e-cigarette users had an increased probability of binge alcohol use relative to non-users. CONCLUSIONS SM young adults' tobacco use varies across the diverse product landscape. Failing to account for a range of tobacco behaviors and nicotine dependence prevents tailoring interventions that should also address concerns such as depressive symptoms, cannabis use, and binge alcohol use.

Abstract
Purpose
This paper aims to overview the need for tobacco harm reduction, the consumer products that facilitate tobacco harm reduction and the barriers to its implementation. The worldwide endemic of tobacco smoking results in the death of over seven million smokers a year. Cigarette quit rates are very low, from 3%–12%, and relapse rates are high, from 75%–80% in the first six months and 30%–40% even after one year of abstinence. In addition, some smokers do not desire to quit. Cigarette substitution in tobacco harm reduction is one strategy that may reduce the burden of morbidity and mortality.
Design/methodology/approach
This review examines the displacement of smoking through substitution of non-combustible low-risk products such as snus, heated tobacco products and e-cigarettes.
Findings
Toxicological testing, population studies, clinical trials and randomized controlled trials demonstrate the potential reductions in exposures for smokers. Many barriers impede the implementation of product substitution in tobacco harm reduction. These products have been subjected to regulatory bans and heavy taxation and are rejected by smokers and society based on misperceptions about nicotine, sensational media headlines and unsubstantiated fears of youth addiction. These barriers will need to be addressed if tobacco harm reduction is to make the maximum impact on the tobacco endemic.
Originality/value
This review provides the rationale for tobacco harm reduction, evaluates the current products available and identifies the barriers to implementation.

Abstract
As the prevalence rates of cigarette use have declined over the past decade, use of electronic cigarettes (e-cigarettes) continues to increase, and companies are heavily invested in manufacturing new e-cigarette products. Scientists are therefore studying e-cigarette use at a rapid rate, generally by conceptualizing e-cigarettes as similar to traditional cigarettes in their use and effects. Thinking of e-cigarettes as largely comparable with cigarettes, however, fails to capture the unique e-cigarette capabilities, user experiences, and effects on nicotine dependence and even health. Assuming that e-cigarette users puff on their devices as they do cigarettes to attain doses of nicotine comparable in magnitude and asking questions about e-cigarette use modeled after how smoking behavior has been usually assessed (eg, puff number, duration, number of cigarettes per day) may miss important differences. A greater appreciation of the distinct uniqueness of e-cigarettes, as compared with cigarettes, will help to accelerate innovative research on e-cigarettes and other electronic devices, leading to new theoretical models and behavioral measures. IMPLICATIONS With research about electronic cigarettes (e-cigarettes) rapidly increasing, this commentary addresses the conceptualization of e-cigarettes as similar to traditional cigarettes. The more we attempt to understand and measure e-cigarettes as equivalent to cigarettes, the more likely research may err in conclusions about these unique devices. Our commentary notes how using unique conceptualizations and measures for e-cigarettes will help accelerate new research.

Abstract
BACKGROUND Limited research has examined indicators of electronic cigarette (ECIG) dependence. Researchers have adapted ECIG dependence measures from cigarette smoking dependence measures, but few have examined unique aspects of ECIG dependence. This study used concept mapping, a mixed-methods approach to examine ECIG user-identified indicators of ECIG dependence. METHODS In 2019, we recruited current ECIG users (n = 75; 52.9 % women; mean age = 33.2, SD = 9.9) from 25 states to complete an online study. Participants completed a brief survey and brainstormed statements (n = 216) completing the prompt: "Something specific that makes me think I am addicted to using my electronic cigarette/vaping device is…" After duplicate content was removed, participants sorted the final list of 93 statements by content similarity and rated statements on how true statements were for them (1 - Definitely NOT true to 7 - Definitely true). Multidimensional scaling analysis identified ECIG dependence thematic clusters. RESULTS We identified ten themes: Craving, Negative Affect, Vaping as a Necessity, Therapeutic Effects, Preparedness, Attachment to Device, Impact on Daily Activity, Physical Withdrawal Symptoms, Monetary Cost, and Shame or Embarrassment. Those who had higher ECIG dependence scores and those who reported more frequent ECIG use had higher mean cluster ratings than those with lower ECIG dependence scores and who reported less frequent ECIG use. (ps<.05). CONCLUSIONS ECIG dependence has similarities to cigarette smoking dependence, but dependence indicators appear to be unique to ECIG use. Health professionals and the public should be aware of ECIG dependence risk and indicators.

Abstract
This study sought to determine brain nicotine kinetics from use of the increasingly popular electronic cigarette (E-cig). Methods: In 17 E-cig users (9 men and 8 women), brain uptake of nicotine after inhalation from E-cigs was directly assessed using 11C-nicotine PET. The brain nicotine kinetics were compared with those from smoking combustible cigarettes (C-cigs). Results: A single puff of E-cig vapor caused the nicotine concentration in the brain to rise quickly (mean time to reach 50% of maximum brain nicotine concentration, 27 s), with a peak amplitude 25% higher in women than men, resembling previous observations with C-cigs. Nonetheless, the accumulation from E-cigs (24%) was less than that from C-cigs (32%) in both men and women. Conclusion: E-cigs can deliver nicotine to the brain with a rapidity similar to that of C-cigs. Therefore, to the extent that rapid brain uptake promotes smoking reward, E-cigs might maintain a degree of nicotine dependence and also serve as a noncombustible substitute for cigarettes.

Abstract
BACKGROUND AND AIMS The long-term population health impact of nicotine vaping products (NVPs) use among smokers is unknown, and subject to a range of plausible assumptions about the use and health consequences of NVPs. While NVPs use may substitute for cigarette smoking and thereby aid in quitting cigarette use, it is also possible that smokers who would have otherwise quit would instead delay quitting cigarettes. We aimed to develop a cohort-specific simulation model of the impact of NVPs on smoking cessation by adult smokers and resulting premature deaths (PD) and life years lost (LYL). DESIGN A cohort-specific simulation model of the impact of NVPs on smoking cessation by adult smokers and resulting premature deaths (PD) and life years lost (LYL) was developed by gender for two birth cohorts, aged 30 and 50 years in 2012. Extensive sensitivity analyses were conducted. SETTING United States. PARTICIPANTS Smokers in two birth cohorts, aged 30 and 50 years in 2012. MEASUREMENTS Data were from the 1965-2012 National Health Interview Surveys and the 2014/15 Tobacco Use Supplement of the Current Population Survey. The model incorporated a range of plausible assumptions from published literature about transition rates from regular smoking to exclusive NVP and dual use, from dual use to exclusive NVP use and from exclusive NVP use to no use. FINDINGS Compared with the no-NVP scenario, the male (female) model projected 17.8% (19.3%) fewer PDs and 22.9% (26.6%) fewer LYL for the 1982 cohort and 5.4% (7.3%) fewer PDs and 7.9% (11.4%) fewer LYL for the 1962 cohort. These gains were sensitive to NVP use over time, age of initial NVP use, transitions from smoking to dual, exclusive NVP and no use and relative NVP mortality risks. CONCLUSIONS Nicotine vaping product (NVP) use in the United States is projected to have a net positive impact on population health over a wide range of plausible levels of NVP use, transitions to dual, exclusive NVP and no use and NVP risks. However, net impact is sensitive to parameter estimates.

Abstract
Tobacco-related morbidity and mortality continue to be a significant public health concern. Unfortunately, current FDA-approved smoking cessation pharmacotherapies have limited efficacy and are associated with high rates of relapse. Therefore, a better understanding of the neurobiological and neurophysiological mechanisms that promote smoking relapse is needed to develop novel smoking cessation medications. Here, we review preclinical studies focused on identifying the neurotransmitter and neuromodulator systems that mediate nicotine relapse, often modeled in laboratory animals using the reinstatement paradigm, as well as the plasticity-dependent neurophysiological mechanisms that facilitate nicotine reinstatement. Particular emphasis is placed on how these neuroadaptations relate to smoking relapse in humans. We also highlight a number of important gaps in our understanding of the neural mechanisms underlying nicotine reinstatement and critical future directions, which may lead toward the development of novel, target pharmacotherapies for smoking cessation.

Abstract
Background. Determining the public health impact of tobacco harm reduction strategies requires the assessment of consumer perception and behavior associated with tobacco and nicotine products (TNPs) with different exposure and risk profiles. In this context, rigorous methods to develop and validate psychometrically sound self-report instruments to measure consumers' responses to TNPs are needed. Methods. Consistent with best practice guidelines, including the U.S. Food and Drug Administration's "Guidance for Industry Patient-Reported Outcome Measures: Use in Medical Product Development to Support Labeling Claims," scientifically designed, fit-for-purpose, reliable, and valid instruments are now being applied to tobacco regulatory research. Results. This brief report presents the ABOUT™ Toolbox ( Assessment of Behavioral OUtcomes related to Tobacco and nicotine products) initiative. This communication: (1) describes the methodological steps followed for the development and validation of the measurement instruments included in the ABOUT™ Toolbox, (2) presents a summary of the high-priority tobacco-related domains that are currently covered in the ABOUT™ Toolbox (i.e., risk perception, dependence, product experience, health and functioning, and use history), and (3) details how the measurement instruments are made accessible to the scientific community. Conclusions. By making the ABOUT™ Toolbox available to the tobacco research and public health community, we envision a rapidly expanding knowledge base, with the goals of (1) supporting consumer perception and behavior research to allow comparisons across a wide spectrum of TNPs, (2) enabling public health and regulatory communities to make better-informed decisions for future regulation of TNPs, and (3) enhancing surveillance activities associated with the impact of TNPs on population health.

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
INTRODUCTION The potential of e-cigarettes to elicit symptoms of nicotine dependence has not been adequately studied, particularly in adolescent populations. The present study examined the prevalence of e-cigarette-specific symptoms of nicotine dependence ("symptoms of e-cigarette dependence") and the associations between these symptoms, e-cigarette usage group, and e-cigarette cessation-related items among Texas adolescents. METHODS This study involved a cross-sectional analysis of adolescents from Wave 4 of the Texas Adolescent Tobacco and Marketing Surveillance System (TATAMS) (n = 2891/N = 461,069). Chi-Square analyses examined differences in the prevalence of symptoms of dependence by e-cigarette usage group (exclusive versus dual users of e-cigarettes and combustible tobacco products) and demographic characteristics. Weighted multivariable logistic regression analyses examined the associations between symptoms of e-cigarette dependence, e-cigarette usage group, and e-cigarette cessation items. RESULTS Exclusive e-cigarette users experienced symptoms of e-cigarette dependence, although the prevalence of most of the symptoms was higher for dual users. Adolescents who reported more symptoms of dependence were less likely to report both wanting to quit e-cigarettes and a past-year quit attempt for e-cigarettes (adjusted odds ratio "AOR" = 0.61 (95% CI = 0.41, 0.92) and AOR = 0.52 (95% CI = 0.30, 0.92), respectively). CONCLUSIONS This study is the first to demonstrate that adolescent e-cigarette users are experiencing symptoms of dependence specific to e-cigarettes. In addition, symptoms of dependence may be barriers to e-cigarette cessation. Future research is needed to determine if characteristics of e-cigarette use (e.g. frequency and intensity) are associated with dependence.

Abstract
Background Alternative tobacco product (ATP) use as well as co-use of various tobacco products has increased in recent years, particularly among young adults. However, little is known about the differential role of motives for ATP or polytobacco use. Methods We examined (1) motives for tobacco use in relation to polytobacco versus cigarette only use and (2) motives for tobacco use in relation to levels of tobacco use across products. We analyzed data from past 30-day tobacco users at Wave 2 (Spring 2015) of a six-wave longitudinal study of 3418 students aged 18-25 years from seven U.S. colleges/universities. Variables included sociodemographics, tobacco use (cigarettes, little cigars/cigarillos [LCCs], smokeless tobacco [SLT], hookah, and e-cigarettes), and tobacco use motives (social, self-enhancement, boredom relief, and affect regulation). Results Multivariate analyses found that boredom relief motives were associated with polytobacco use versus cigarette only use (p = .007). Higher consumption levels demonstrated the following associations: cigarettes-positively with boredom relief (p = .025) and affect regulation motives (p < .001); LCCs-positively with affect regulation motives (p = .035); SLT-negatively with social (p = .003) and positively with self-enhancement (p = .017) and boredom relief motives (p = .007); and hookah-positively with social (p = .002) and boredom relief motives (p = .033) and negatively with self-enhancement (p = .004) and affect regulation motives (p = .001). Conclusions Distinct motives for use were associated with polytobacco use among smokers. Moreover, higher levels of use among single product users also demonstrated distinct associations across use motives. These data should inform targeted cessation interventions addressing motives for use in ATP and polytobacco users. Implications Interventionists, public health practitioners, and health care providers must address the increasing issue of ATP and polytobacco use and tailor interventions to reduce ATP and polytobacco use in light of the distinct motives for use.

Assessment of the abuse liability of three menthol Vuse Solo electronic cigarettes relative to combustible cigarettes and nicotine gum. Psychopharmacology (Berl) 2018; 235:2077-2086. [PMID: 29725702 PMCID: PMC6015619 DOI: 10.1007/s00213-018-4904-x] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2017] [Accepted: 04/10/2018] [Indexed: 11/29/2022]
Abstract
RATIONALE We previously reported that following a short-term product use period, use of non-menthol Vuse Solo electronic cigarettes (ECs) resulted in product effect-related subjective responses and nicotine uptake between those of combustible cigarettes (high-abuse liability comparator) and nicotine gum (low-abuse liability comparator); the results were generally closer to those of nicotine gum. OBJECTIVE Using a similar design to the previous study, we evaluated the abuse liability of three menthol-flavored Vuse Solo ECs with the same nicotine contents (14, 29, and 36 mg) in a group of EC-naïve, menthol cigarette smokers, relative to comparator products. METHODS Six-hour nicotine uptake and ratings of subjective effects were used to determine abuse liability and pharmacokinetics. RESULTS Use of menthol Vuse Solo resulted in significantly lower responses to subjective measurements (product liking, intent to use product again, and liking of positive product effects), higher urge to smoke responses, and a lower peak (Cmax) and overall extent (AUC0-360) of nicotine uptake compared to smoking the usual brand menthol cigarette. When compared with use of nicotine gum, subjective responses to use of menthol Vuse ECs were in the same direction as those resulting from smoking cigarettes but were more similar to nicotine gum use in magnitude than they were to cigarettes. CONCLUSION These findings are concordant with our previous results and provide evidence that menthol Vuse Solo ECs have abuse liability that is lower than menthol cigarettes and potentially greater than that of nicotine gum.

Cigarette use trajectories in young adults: Analyses of predictors across system levels. Drug Alcohol Depend 2018; 188:281-287. [PMID: 29807215 PMCID: PMC6819815 DOI: 10.1016/j.drugalcdep.2018.03.055] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2017] [Revised: 02/23/2018] [Accepted: 03/28/2018] [Indexed: 11/27/2022]
Abstract
BACKGROUND Cigarette smoking escalates most in early to middle young adulthood. However, little research has examined a range of multilevel factors in relation to smoking trajectories during this time. METHODS We examined: 1) trajectories of cigarette smoking among 2967 US college students (aged 18-25) in a two-year, six-wave longitudinal study (using growth mixture modeling); and 2) intrapersonal- (i.e., other substance use, depressive symptoms, ADHD symptoms,); interpersonal- (i.e., adverse childhood events, social support, parental tobacco and marijuana use), and community-level (i.e., type of college, rural vs. urban setting) predictors of differing trajectories (using multinomial logistic regression). RESULTS We identified three trajectory classes: 1) Dabblers, who used cigarettes at one point in their life or not at all (85.6%); 2) College Onset Smokers, who began smoking regularly during the college years (6.2%); and 3) Later Onset Smokers, who began smoking during the mid- to late-20 s (8.2%). Multinomial regression (with Dabblers as the reference group) showed that predictors of being College Onset Smokers included being male (p = .031); Asian (p = .001) but not Black (p = .008; Ref: White); early onset smokers (i.e., initiation before age 15; p = .006); past 30-day users of little cigars/cigarillos (p = .024), alcohol (p < .001), and marijuana (p = .008); children of tobacco users (p = .050); and public (p = .031) or a technical college students (p < .001; Ref: private college); predictors of being Later Onset Smokers were being male (p = .019) and technical college students (p = .005). CONCLUSIONS Despite some young adults' smoking initiating/escalating in middle young adulthood, few risk factors were documented. This understudied period warrants greater examination to inform intervention.

Abstract
INTRODUCTION The use of alternative tobacco products (ATPs) is becoming increasingly popular among the youth. This study aimed to assess cigarette-only smoking, exclusive ATP use, and concurrent use (cigarettes and ATPs) among adolescents in Hong Kong. METHODS We analyzed data of the Hong Kong School-based Survey on Smoking among Students 2012/13 from a representative sample of 45 857 secondary school students. Weighted prevalence of cigarette-only smoking, exclusive ATP use, and concurrent tobacco use were calculated. Multinomial logistic regression examined correlates of exclusive ATP use and concurrent use relative to cigarette-only smoking. Among current (past-30-days) cigarette smokers, multivariable logistic regression assessed whether ATP use was associated with nicotine dependence, quit intention and quit attempt. RESULTS Overall, 5.8% of adolescents reported current tobacco use (2.1% cigarette-only smoking, 2.5% exclusive ATP use and 1.2% concurrent use). Compared with cigarette-only smoking, exclusive ATP use and concurrent tobacco use were associated with younger age, higher perceived family financial status, absence of cigarette smoking peers, poor knowledge about smoking and more frequent alcohol use. Among current cigarette smokers, ATP use was negatively associated with cigarette quit intention and quit attempt. CONCLUSIONS ATP use was as prevalent as cigarette smoking among adolescents, and ATP users were different from cigarette smokers in many demographic and psychosocial factors. Tobacco control programs among youth should target different types of tobacco users and address all forms of tobacco products.

Abstract
Introduction Fagerström Test for Nicotine Dependence (FTND) is the most commonly used measure of dependence among tobacco users. Psychometric properties of FTND have been validated among cigarette smokers, but the reliability and validity of its variant for smokeless tobacco (ST) users (FTND-ST) is not well documented. The objective of the present study is to evaluate reliability, construct validity, and structure model of FTND-ST. Methods Data from 95 exclusive ST users living in Oklahoma were used for this study. Participants completed a self-administered mail survey including FTND-ST and other questionnaires. Measures of internal consistency, Cronbach's coefficient α and item-total correlation were estimated to evaluate reliability of the FTND-ST. To ascertain the factor structure of the scale, confirmatory factor analysis was performed. We examined concurrent and construct validity with correlation and regression analysis. Salivary cotinine concentration was used as a criterion variable. Results The FTND-ST demonstrated good reliability with acceptable Cronbach's coefficient (α = 0.72) and significant item-total correlations. Study findings showed that FTND-ST had positive significant association with salivary cotinine concentration (r = 0.61, p <.0001) and Tobacco Dependence Screener (r = 0.44, p < .0001). Results of factor analysis support a unidimensional factor structure of FTND-ST. Conclusions The FTND-ST demonstrated good psychometric properties. The unidimensional structure of the scale indicates that it measures single clearly defined aspect of dependence, physical dependence. Given its good reliability and demonstrated construct validity, FTND-ST is a useful measure of dependence among ST users. Implications Because of the paucity of ST dependence research, there are limited studies evaluating ST dependence measures. Although the FTND was exclusively developed for cigarette smoking, it has been adapted for ST users in the form of FTND-ST. This is the first study to examine reliability, concurrent and construct validity, and structure model of FTND-ST among regular ST users. Findings suggest that the FTND-ST measures physical aspect of dependence. Good psychometric properties of FTND-ST and its orientation as a continuous scale indicate that FTND-ST is a useful measure of dependence among ST users.

Abstract
Objectives To examine factors important to cigar smoking and subsequent nicotine exposure, we evaluated the impact of cigar type, cigarette smoking history, and inhalation behaviors on nicotine dependence, smoking topography, and biomarkers of exposure in current exclusive cigar smokers. Methods Adult, exclusive cigar smokers (N = 77) were recruited based on cigar type, cigarette smoking history, and self-reported inhalation behaviors. Participants smoked their own brand product ad libitum for up to one hour; dependence symptoms, smoking topography, and biomarkers of exposure were assessed. Results Cigar smokers showed low levels of dependence. Cigar smoking alleviated withdrawal and craving symptoms, increased plasma nicotine concentration, and increased exhaled CO. Multiple regression analyses indicate that inhalation behaviors were associated with increased dependence and greater reductions in withdrawal symptoms upon cigar smoking. Large cigar smokers smoked longer and smoked more tobacco than small cigar and cigarillo smokers. Furthermore, large cigar smokers and self-reported inhalers were exposed to more nicotine than small cigar smokers and non-inhalers. Conclusions Our study suggests that cigar type and smoking behaviors affect dependence and nicotine exposure upon cigar smoking. These findings provide additional insight into the substantial risks associated with cigar smoking.

THE AMERICAN JOURNAL OF DRUG AND ALCOHOL ABUSE 2017; 43:694-702. [PMID: 27668320 PMCID: PMC5440212 DOI: 10.1080/00952990.2016.1225072] [Citation(s) in RCA: 54] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/18/2016] [Revised: 07/19/2016] [Accepted: 07/31/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Despite significant declines in youth cigarette smoking, overall tobacco usage remains over 20% as non-cigarette tobacco product usage is increasingly common and polytobacco use (using 1+ tobacco product) remains steady. OBJECTIVES The present study was designed to identify patterns of youth tobacco use and examine associations with sociodemographic characteristics and tobacco dependence. METHODS The current analysis uses Latent Class Analysis (LCA) to examine the 6,958 tobacco users (n = 2,738 female) in the National Youth Tobacco Survey (2012 and 2013). We used as indicators past month use of tobacco products (cigarettes, cigars, smokeless tobacco, e-cigarettes, hookah, snus, pipes, bidis, and kreteks) and regressed resulting classes on sociodemographic characteristics and tobacco dependence. RESULTS Nine classes emerged: cigarette smokers (33.4% of sample, also included small probabilities for use of cigars and e-cigarettes), cigar smokers (16.8%, nearly exclusive), smokeless tobacco users (12.3%, also included small probabilities for cigarettes, cigars, snus), hookah smokers (11.8%), tobacco smokers/chewers (10.7%, variety of primarily traditional tobacco products), tobacco/hookah smokers (7.2%), tobacco/snus/e-cig users (3.3%), e-cigarette users (2.9%,), and polytobacco users (1.7%, high probabilities for all products). Compared to cigarette smokers, tobacco/hookah smokers and hookah smokers were more likely to report Hispanic ethnicity. Polytobacco users were more likely to report dependence (AOR:2.77, 95% CI:[1.49-5.18]), whereas e-cigarette users were less likely (AOR:0.49, 95% CI:[0.24-0.97]). CONCLUSION Findings are consistent with other research demonstrating shifts in adolescent tobacco product usage towards non-cigarette tobacco products. Continuous monitoring of these patterns is needed to help predict if this shift will ultimately result in improved public health.

Abstract
INTRODUCTION There is considerable interest in using brief measures of dependence for evaluation and treatment of tobacco dependence. The Heaviness of Smoking Index (HSI) is a validated measure of dependence among cigarette smokers. However, a similar index has not been studied among ST users. The aim of this study is to develop similar ST use indices and evaluate their utility as concise dependence measures. Time to first chew/dip of the day (TTFD), number of cans of ST used per week (CPW), and number of dips/chews per day (DPD) were used to create three ST use indices; heaviness of ST use index (HSTI), ST dependence index (STDI), and ST quantity frequency index (ST-QFI). METHODS The study was based on data collected from a community based sample of exclusive ST users living in Oklahoma. Participants completed the self-administered survey which included dependence scales and questionnaires to measure sociodemographic factors and tobacco use characteristics. Saliva samples were obtained to measure cotinine concentration. Method of scoring for TTFD and DPD was similar to the scoring scheme employed for HSI items. DPD was transformed by a series of statistical tests into a three category scoring variable. Concurrent validity and reliability of the ST use indices were evaluated and overall accuracy of ST use indices was assessed. Level of agreement between the ST use indices and Fagerström Test for Nicotine Dependence for ST users (FTND-ST) was calculated to find the extent these indices were equivalent to FTND-ST in measuring dependence. RESULTS ST use indices were significantly correlated with FTND-ST. ST users who had higher HSTI or STDI scores were more likely to have Tobacco Dependence Screener (TDS) based dependence diagnosis (OR: 1.50, 95%CI: 1.12, 2.02 and OR: 1.53, 95%CI: 1.16, 2.02, respectively). Study findings showed that all ST use indices were predictors of cotinine concentration. The internal consistency assessed by Cronbach's alpha indicated that STDI had acceptable reliability. At the optimal cutoff scores, both HSTI and STDI had good level of agreement with FTND-ST (k=0.81, p<0.0001 and k=0.71, p≤0.0001, respectively). CONCLUSIONS Components of physical dependence are interrelated and each ST use item, TTFD, CPW, and DPD, explains a different dependence feature. Significant association of HSTI and STDI with other tobacco dependence measures and FTND-ST suggests that these indices are valuable brief measures of dependence among ST users and can be used as a substitute for FTND-ST, similar to HSI in smoking dependence studies. A concise dependence measure like HSTI or STDI has reduced response burden and is an effective tool in clinical and research setting.

Abstract
INTRODUCTION Studies of the health effects of moist oral tobacco, snus, have produced inconsistent results. The main objective of this study is to examine the health effects of snus use on asthma, respiratory symptoms and sleep-related problems, a field that has not been investigated before. METHODS AND MATERIAL This cross-sectional study was based on a postal questionnaire completed by 26 697 (59.3%) participants aged 16 to 75 years and living in Sweden. The questionnaire included questions on tobacco use, asthma, respiratory symptoms and sleeping problems. The association of snus use with asthma, respiratory symptoms and sleep-related symptoms was mainly tested in never-smokers (n=16 082). RESULTS The current use of snus in never-smokers was associated with an increased risk of asthma (OR 1.51 (95% CI 1.28 to 1.77)), asthmatic symptoms, chronic bronchitis and chronic rhinosinusitis. This association was not present among ex-snus users. Snoring was independently related to both the former and current use of snus ((OR 1.37 (95% CI 1.12 to 1.68)) and (OR 1.59 (95% CI 1.34 to 1.89), respectively)). A higher risk of difficulty inducing sleep was seen among snus users. CONCLUSION Snus use was associated with a higher prevalence of asthma, respiratory symptoms and snoring. Healthcare professionals should be aware of these possible adverse effects of snus use.

Abstract
Electronic cigarettes (ECIGs) use electricity to power a heating element that aerosolizes a liquid containing solvents, flavorants, and the dependence-producing drug nicotine for user inhalation. ECIGs have evolved rapidly in the past 8 years, and the changes in product design and liquid constituents affect the resulting toxicant yield in the aerosol and delivery to the user. This rapid evolution has been accompanied by dramatic increases in ECIG use prevalence in many countries among adults and, especially, adolescents in the United States. The increased prevalence of ECIGs that deliver nicotine and other toxicants to users' lungs drives a rapidly growing research effort. This review highlights the most recent information regarding the design of ECIGs and their liquid and aerosol constituents, the epidemiology of ECIG use among adolescents and adults (including correlates of ECIG use), and preclinical and clinical research regarding ECIG effects. The current literature suggests a strong rationale for an empirical regulatory approach toward ECIGs that balances any potential ECIG-mediated decreases in health risks for smokers who use them as substitutes for tobacco cigarettes against any increased risks for nonsmokers who may be attracted to them.

Abstract
Waterpipe tobacco usage is spreading rapidly worldwide, with reports of more youth being waterpipe users compared to adults. In many areas of the world, waterpipe usage surpasses cigarette smoking. Waterpipes and cigarettes are both mechanisms for inhalation of tobacco smoke and therefore have serious health consequences. However, because of the many differences between the two products, prevention and control strategies that have proven effective for cigarettes may not transfer readily to waterpipe. This report highlights the differences between waterpipes and cigarettes in toxicant exposure and physiologic effects, patterns of use, social norms, the extent of evidence, and the policy environment. There is little evidence to date around effective interventions for waterpipe prevention and control. The current state of evidence for intervention to curb or control waterpipe is at ground zero and critically needs attention from both scientists and policy makers. National and global efforts aimed at cigarette prevention have succeeded, particularly in developed countries. We suggest the time has come to harness what we know works for cigarette prevention and control and adapt it to tackle the growing epidemic of waterpipe tobacco use.

Abstract
CONTEXT Rapid developments in e-cigarettes, or electronic nicotine delivery systems (ENDS), and the evolution of the overall tobacco product marketplace warrant frequent evaluation of the published literature. The purpose of this article is to report updated findings from a comprehensive review of the published scientific literature on ENDS. EVIDENCE ACQUISITION The authors conducted a systematic review of published empirical research literature on ENDS through May 31, 2016, using a detailed search strategy in the PubMed electronic database, expert review, and additional targeted searches. Included studies presented empirical findings and were coded to at least one of nine topics: (1) Product Features; (2) Health Effects; (3) Consumer Perceptions; (4) Patterns of Use; (5) Potential to Induce Dependence; (6) Smoking Cessation; (7) Marketing and Communication; (8) Sales; and (9) Policies; reviews and commentaries were excluded. Data from included studies were extracted by multiple coders (October 2015 to August 2016) into a standardized form and synthesized qualitatively by topic. EVIDENCE SYNTHESIS There were 687 articles included in this systematic review. The majority of studies assessed patterns of ENDS use and consumer perceptions of ENDS, followed by studies examining health effects of vaping and product features. CONCLUSIONS Studies indicate that ENDS are increasing in use, particularly among current smokers, pose substantially less harm to smokers than cigarettes, are being used to reduce/quit smoking, and are widely available. More longitudinal studies and controlled trials are needed to evaluate the impact of ENDS on population-level tobacco use and determine the health effects of longer-term vaping.

Abstract
RATIONALE Electronic cigarettes (ECs) are becoming popular alternatives for smokers, but there has been limited study of their abuse liability. OBJECTIVES The objective of this study was to evaluate the abuse liability of three Vuse Solo ECs, ranging from 14 to 36 mg in nicotine content, relative to high- and low-abuse liability comparator products (usual brand combustible cigarettes and nicotine gum, respectively) in a group of 45 EC-naïve smokers. METHODS Enrolled subjects' ratings of subjective effects and nicotine uptake over 6 h were used to measure abuse liability and pharmacokinetics following in-clinic use of each EC. RESULTS Use of Vuse Solo resulted in subjective measures and nicotine uptake that were between those of combustible cigarettes and nicotine gum, although generally closer to nicotine gum. Compared to combustible cigarettes, use of Vuse Solo resulted in significantly lower scores in measures of product liking, positive effects, and intent to use again. These pharmacodynamic findings were consistent with the pharmacokinetic data, showing that cigarettes produced substantially faster and higher levels of nicotine uptake as compared to Vuse Solo and nicotine gum. Vuse Solo resulted in more rapid initial uptake of nicotine compared to nicotine gum, but peak concentration and long-term extent of uptake were not different or were lower with Vuse. CONCLUSIONS Collectively, these findings suggest that Vuse Solo likely has an abuse liability that is somewhat greater than nicotine gum but lower than cigarettes.

Abstract
BACKGROUND Snus tobacco characteristics may attract non-tobacco users, including relatively low, but pharmacologically active, doses of nicotine. Lower nicotine doses may limit adverse drug effects while also producing a physiologically active response. OBJECTIVES This pilot study is the first to profile the acute effects of snus on physiological and subjective assessments in a sample of never-tobacco users. METHODS Eleven never-tobacco users (five women; <100 uses/lifetime) were recruited from the community via university-approved advertisements. Using a within-subject design, participants consumed six pouches in ascending dose order (0, 1.6, 3.2, 4.8, 6.4, and 8.0 mg nicotine) within one session. The start of each snus bout was separated by 45 minutes, and pre- and post-pouch assessments included ratings of drug effects and physiological response. RESULTS The average heart rate and systolic blood pressure increased significantly from pre- to post-pouch use as a function of dose, though these increases were reliable for 8.0 mg nicotine only (p < .05). Collapsed across time, diastolic blood pressure was significantly higher for 8.0 mg nicotine than for all other doses (p < .05). Subjective ratings for "excessive salivation" and "satisfying" increased significantly from pre- to post-pouch use (p < .05), independent of dose. CONCLUSION Significant increases in physiological response at some doses suggest that users were exposed to pharmacologically active doses of nicotine. The lack of reliable subjective effects may be the product of the dosing regimen or the relatively small sample size. Findings highlight the need for identification of doses of snus that may promote abuse among naïve users.

Abstract
BACKGROUND Although waterpipe smoking is increasingly popular among youth and can lead to nicotine dependence (ND), no studies have documented how ND develops in waterpipe smokers. We examined the emerging symptoms of ND among adolescent waterpipe smokers in Lebanon. METHODS Individual confidential interviews were used to evaluate ND in 160 waterpipe smokers and 24 cigarette smokers from a sample of 498 students enrolled in 8th and 9th grades in Lebanon. RESULTS Among waterpipe smokers, 71.3% endorsed at least one Hooked on Nicotine Checklist (HONC) symptom and 38.1% developed the full syndrome of ND (≥3 criteria using the International Classification of Diseases, 10th revision). The early symptoms of ND among waterpipe smokers were craving (25%), feeling addicted (22.5%), and failed quit attempts (14.3%). Among those who reached the respective milestones, median tobacco use when the first HONC symptom emerged was 7.5 waterpipes/month with smoking frequency of 6 days/month; the median tobacco use for the full syndrome of ND was 15 waterpipes/month with smoking frequency of 15 days/month. Among those who had already reached these milestones, the first HONC symptom appeared 10.9 months after the initiation of waterpipe smoking, and the full syndrome of ND was reached at 13.9 months. In addition, cues such as seeing or smelling waterpipe, and the café environment triggered craving in most waterpipe smokers with symptoms of ND. CONCLUSIONS Symptoms of ND develop among adolescent waterpipe smokers at low levels of consumption and frequency of use. Craving for nicotine triggered by waterpipe-specific cues is reported even at this young age. Waterpipe-specific ND prevention and intervention programmes for youth are needed.

Abstract
There has been concern that the availability of alternative less harmful forms of nicotine might inhibit smoking cessation and/or encourage those who would not otherwise have smoked to do so. The plausibility of such effects can be best assessed by looking at population trends in use of smoking in relation to alternatives. This paper looks at the relationships between snus use and smoking in Sweden. Analyses are based on a data set for the period January 2003 to February 2011 from a long-term study covering nationally representative samples of the Swedish population aged 18–79, with a total study population of 60,675 individuals. Questionnaires made it possible to identify detailed tobacco use categories and use trajectories. The results showed that uptake of snus use is much more common in males than females. Those who began daily tobacco use using snus were much less likely to subsequently take up smoking than those who had not, both among males (17.6% vs. 45.9%), and females (8.2% vs. 40.2%). Further, among those who started using snus after starting as smokers, 76.3% of men and 71.6% of women had stopped smoking completely, including 31.5% of the men and 28.6% of the women who had quit all forms of tobacco. Indeed, those who were primary snus users were also more likely to have quit altogether than those who only ever smoked. Snus was also reported as the most common smoking cessation aid among men and yielded higher success rates than nicotine replacement therapy and other alternatives. As conclusions, snus has both contributed to decreasing initiation of smoking and, when used subsequent to smoking, appears to facilitate smoking cessation. All these effects suggest that the availability and use of snus has been a major factor behind Sweden’s record-low prevalence of smoking and the lowest level of tobacco-related mortality among men in Europe.

Abstract
OBJECTIVE Evaluating electronic cigarettes (ECIGs) in the clinical laboratory is critical to understanding their effects. However, laboratory evaluation of ECIGs can be challenging, as they are a novel, varied, and evolving class of products. The objective of this paper is to describe some methodological challenges to the clinical laboratory evaluation of ECIGs. METHODS The authors gathered information about challenges involved in the laboratory evaluation of ECIGs. Challenges were categorized and solutions provided when possible. RESULTS Methods used to study combustible cigarettes may need to be adapted to account for ECIG novelty and differences within the class. Challenges to ECIG evaluation can include issues related to 1) identification of ECIG devices and liquids, 2) determination of short -term ECIG abstinence, 3) measurement of use behavior, and 4) assessment of dependence. These challenges are discussed, and some suggestions to inform ECIG evaluation using clinical laboratory methods are provided. CONCLUSIONS Awareness of challenges and developing, validating, and reporting methods used to address them aids interpretation of results and replication efforts, thus enhancing the rigor of science used to protect public health through appropriate, empirically-based, ECIG regulation.

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
The present overview focuses on evidence of smoking cessation approaches in oncology settings with the aim to provide health personnel a critical perspective on how to help their patients. This narrative review is structured in two main sections: the first one describes the psycho-cognitive variables involved in the decision to continue smoking after a cancer diagnosis and during the treatment; the second section relates methods and tools may be recommended, being evidence-based, to support smoking cessation in oncology settings. Active smoking increases not only susceptibility to common cancers in the general population, but also increases disease severity and comorbidities in cancer patients. Nowadays, scientific evidence has identified many strategies to give up smoking, but a lack of knowledge exists for treatment of nicotine dependence in the cancer population. Health personnel is often ambiguous when approaching the problem, while their contribution is essential in guiding patients towards healthier choices. We argue that smoking treatments for cancer patients deserve more attention and that clinical features, individual characteristics and needs of the patient should be assessed in order to increase the attempts success rate. Health personnel that daily work and interact with cancer patients and their caregivers have a fundamental role in the promotion of the health changing. For this reason, it is important that they have adequate knowledge and resources in order to support cancer patients to stop tobacco cigarette smoking and promoting and healthier lifestyle.

Abstract
INTRODUCTION Limited research has examined reasons for polytobacco use, an increasing public health problem, particularly among young adults. We examined reasons for polytobacco use among users of more than one tobacco product in the past 4 months enrolled in an ongoing six-wave longitudinal study of 3,418 students aged 18-25 from seven US colleges and universities. METHODS An expert panel generated items related to reasons for polytobacco use, included in Wave 3 (administered in Summer 2015). Participants reporting use of more than one tobacco product in the past four months (n=540) were asked to complete the Reasons for Polytobacco Use scale and measures related to tobacco/nicotine use/dependence, use motives, perceptions of tobacco, parental/friend use, other substance use, and mental health. We conducted a factor analysis and then examined convergent and discriminant validity for the derived factors. RESULTS Our sample was an average age of 20.40 (SD=1.84), 48.0% male, and 21.9% Black. Four factors were identified: Instrumentality, Social Context, Displacement, and Experimentation. Instrumentality was the only factor associated with little cigar/cigarillo and marijuana use. Displacement and Social Context showed similar associations; however, Social Context was associated with having friends who used tobacco while Displacement was not. Experimentation was associated with greater perceived addictiveness and harm of using tobacco products as well as greater perceived social acceptability of tobacco use. CONCLUSIONS Each of the four factors identified demonstrated unique convergent and discriminant validity. The use of this scale to characterize polytobacco using young adults may help inform and target cessation or prevention interventions.
