Forberger S, Khan Z, Ahmad F, Ahmed F, Frense J, Kampfmann T, Ullah S, Dogar O, Siddiqi K, Zeeb H. Scoping Review of Existing Evaluations of Smokeless Tobacco Control Policies: What Is Known About Countries Covered, Level of Jurisdictions, Target Groups Studied, and Instruments Evaluated? Nicotine Tob Res 2022; 24:1344-1354. [PMID: 35428887 DOI: 10.1093/ntr/ntac102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 03/17/2022] [Accepted: 04/12/2022] [Indexed: 11/13/2022]
Abstract
OBJECTIVE The implementation of smokeless tobacco control policies lags behind those for smoking. This scoping review summarizes the studies that evaluated public policies on smokeless tobacco regulation (SLT) and provides an overview of the jurisdictional level, target groups, and policy instruments. METHODS Seven databases were systematically searched for studies reporting on public policies regulating SLT. Two reviewers independently screened all studies. Data extraction was performed using a predefined extraction form. Extraction was replicated for 10% of the identified studies for quality assurance. A narrative synthesis of the included studies was used to analyze and interpret the data. The protocol was published beforehand with the Open Science Foundation (OSF). RESULTS Fourty articles comprising 41 studies were included. Most of the studies reported in the articles were conducted in the United States (n = 17) or India (n = 14). Most studies reported outcomes for students (n = 8), retailers/sellers (n = 8), and users/former users (n = 5). The impact of public policies on smokeless tobacco use, in general, was most frequently assessed (n = 9), followed by the impact of taxes (n = 7), product bans (n = 6), sales/advertising bans near educational institutions (n = 4), and health warnings (n = 3) on consumer behavior. CONCLUSIONS There are significant gaps in the evaluation of smokeless tobacco regulation studies that need to be filled by further research to understand the observed outcomes. WHO reporting on Framework Convention on Tobacco Control (FCTC) implementation should be linked to studies evaluating smokeless tobacco control measures at all levels of jurisdictions and in countries not members of the WHO FCTC or do not provide data. IMPLICATION Large gaps in the evaluation of SLT control policies exist. For some countries, WHO FCTC evaluations are available for different levels of jurisdictions. In countries with a strong federal structure, there is a lack of data beyond the national level to provide a more detailed look at compliance, indirect effects, or implementation gaps. More research is needed at all levels of jurisdictions, which add to the work of the WHO to understand what works for which target group, how the different levels of jurisdiction interact, how the real-world context can be incorporated, and what indirect effects may occur.

Sánchez-Romero LM, Yuan Z, Li Y, Levy DT. The Kentucky SimSmoke Tobacco Control Policy Model of Smokeless Tobacco and Cigarette Use. Int J Health Policy Manag 2022; 11:592-609.

Abstract
BACKGROUND Smokeless tobacco (SLT) prevalence was decreasing in Kentucky before 2007, but has since increased. This study examines the impact of policies on cigarette and SLT use by applying the SimSmoke tobacco control policy simulation model. METHODS Using data from the large-scale Tobacco Use Supplement of the Current Population Survey (TUS-CPS) and information on state-specific tobacco policies, Kentucky SimSmoke is updated and extended to incorporate exclusive SLT and dual cigarette and SLT use. The model is validated using survey data through 2017. The model was used to estimate the impact on smoking and SLT prevalence and attributable deaths of policies implemented between 1993 and 2018 and the impact of stronger future policies implemented in 2018 and maintained through 2060. RESULTS SimSmoke generally reflects trends in exclusive cigarette use from the TUS-CPS and the Behavioral Risk Factor Surveillance System (BRFSS), but underestimated the increase in SLT prevalence in recent years. SimSmoke projects that policies implemented between 1993 and 2018 reduced male and female cigarette use by 23.7% and 23.0%, and male and female SLT use by 4.9% by 2018, averting 9018 tobacco-attributable deaths by 2018, increasing to 89 547 by 2060. The largest reductions in cigarette and SLT use were attributed to cigarette price increases. Strengthening tobacco control policies could reduce smoking prevalence by 41% and 40%, and reduce SLT prevalence by 33% and 25% for males and females by 2060. CONCLUSION Our results suggest that cigarette-oriented policies were effective in reducing SLT use but have been less successful in recent years. Future use rates can be further reduced through more restrictive statewide policies, which also target non-combustible nicotine products.

[PMID: 30125019 PMCID: PMC6093419 DOI: 10.1093/ntr/nty050] [Citation(s) in RCA: 93] [Impact Index Per Article: 18.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2017] [Accepted: 03/09/2018] [Indexed: 12/22/2022]
Abstract
Introduction The tobacco product landscape has changed substantially. Little is known about the recent pattern of polytobacco use (at least two tobacco products) among US adults and its relationship to nicotine dependence. Methods Using the 2012–2013 and 2013–2014 National Adult Tobacco Survey (NATS) data (N = 135 425 adults), we analyzed the prevalence and correlates of polytobacco use among each of the six categories of current tobacco user (cigarettes, cigars, pipes, hookah, e-cigarettes, and smokeless tobacco). Based on five nicotine dependence symptom measures from the NATS, difference in the prevalence of dependence symptoms between polytobacco and sole-product users for each category of tobacco user was assessed using multivariable regression analyses. Results During 2012–2014, 25.1% of adults were current users of any tobacco product. Among them, 32.5% were poly users with the largest poly use category being dual use of cigarettes and e-cigarettes (30.2%). Poly use prevalence was the lowest among current cigarette smokers (38.7%), followed by current users of smokeless tobacco (52.4%), hookah (59.2%), cigars (69.3%), e-cigarettes (80.9%), and pipes (86.2%). Among each category of current tobacco user, the prevalence of dependence symptom was consistently greater in polytobacco users than sole users for every symptom measure. After controlling for frequency of use and demographic covariates, the difference in nicotine dependence between poly users and sole users was statistically significant and consistent across all symptom measures for each category of tobacco user. Conclusions Between 52% and 86% of noncigarette tobacco users and nearly 40% of cigarette smokers engaged in polytobacco use. Poly users showed greater nicotine dependence than sole-product tobacco users. Implications This study examines recent patterns of polytobacco use separately for US adult current cigarette smokers, cigar smokers, pipe smokers, hookah users, e-cigarette users, and smokeless tobacco users. By including more tobacco products, particularly e-cigarettes and hookah, this study provides more comprehensive insight into polytobacco use. This study is also unique in comparing nicotine dependence between polytobacco and sole-product users among each category of tobacco users. Our results indicate that polytobacco use is very common and is associated with greater likelihood of reporting nicotine dependence symptoms. Tobacco cessation policies and programs should be tailored to address polytobacco use.

Abstract
BACKGROUND Little is known about how policies and industry activities impact smokeless tobacco demand. We examined how tobacco control policies and retail promotion may affect smokeless tobacco sales. METHODS We used Nielsen market-level retail scanner data for smokeless tobacco sales in convenience stores in 30 US regions from 2005 to 2010. Tobacco policy variables, including excise taxes, state tobacco control program expenditures, and clean indoor air laws, were merged to Nielsen markets. We estimated regression models for per capita unit sales. RESULTS Higher cigarette tax was significantly associated with lower sales volume of smokeless tobacco. Sales of smokeless tobacco in markets with a weight-based SLT excise tax were higher than in markets with an ad valorem tax. A higher average product price was associated with decreased sales overall but results varied by package quantity and brand. CONCLUSIONS This study observed that smokeless tobacco products were both complements and substitutes to cigarettes. Thus, smokeless tobacco may act as complements for some population segments and substitutes for others. A weight-based tax generally favors premium smokeless tobacco products.

Abstract
BACKGROUND This secondary analysis aims to describe, over time, the relationship between HIV disease progression and intention to quit cigarette smoking among current monocigarette users with and without a lifetime history of polytobacco use. METHODS Participants completed a baseline assessment at the time of HIV care initiation and four follow-up assessments (3, 6, 9, and 12-months). Assessments included biochemically verified smoking status and audio computer-assisted self-interviews assessing psychosocial, substance use, and clinical variables known to influence smoking behaviors. Using linear and generalized linear fixed-effects models, we modeled the covariance structure for the repeated outcome measures (intention to quit and 7-day point prevalence smoking abstinence) across the study time points and included a three-way interaction term to examine the effects of disease stage and tobacco product use. RESULTS Participants (N = 357) were 73.1% male, 67.3% black/African American, and had a mean (SD) age of 38.7 (10.6) years. At baseline, lifetime polytobacco users reported significantly worse HIV-related symptoms and burdens, illness perception, social support, and nicotine dependence. Intention to quit, but not smoking abstinence, was predicted by a three-way interaction between time from HIV care initiation, disease progression, and tobacco product use (p = .04). Overall, progressive HIV was associated with greater intention to quit smoking cigarettes. However, the relationship differed over time between the two tobacco product groups. CONCLUSION Future studies should consider tailoring the timing of cessation interventions upon disease stage and lifetime history of polytobacco use.

Abstract
Background Smokeless tobacco (SLT) prevalence had been declining in the US prior to 2002 but has since increased. Knowledge about the impact of tobacco control policies on SLT and cigarette use is limited. This study examines the interrelationship between policies, cigarette use, and SLT use by applying the SimSmoke tobacco control policy simulation model. Methods Using data from large-scale Tobacco Use Supplement and information on policies implemented, US SimSmoke was updated and extended to incorporate SLT use. The model distinguishes between exclusive SLT and dual use of SLT and cigarettes, and considers the effect of implementing individual and combined tobacco control policies on smoking and SLT use, and on deaths attributable to their use. After validating against Tobacco Use Supplement (TUS) survey data through 2015, the model was used to estimate the impact of policies implemented between 1993 and 2017. Results SimSmoke reflected trends in exclusive cigarette use from the TUS, but over-estimated the reductions, especially among 18–24 year olds, until 2002 and under-estimated the reductions from 2011 to 2015. By 2015, SimSmoke projections of exclusive SLT and dual use were close to TUS estimates, but under-estimated reductions in both from 1993 to 2002 and failed to estimate the growth in male exclusive SLT use, especially among 18–24 year olds, from 2011 to 2015. SimSmoke projects that policies implemented between 1993 and 2017 reduced exclusive cigarette use by about 35%, dual use by 32.5% and SLT use by 16.5%, yielding a reduction of 7.5 million tobacco-attributable deaths by 2067. The largest reductions were attributed to tax increases. Conclusions Our results indicate that cigarette-oriented policies may be effective in also reducing the use of other tobacco products. However, further information is needed on the effect of tobacco control policies on exclusive and dual SLT use and the role of industry.

Abstract
INTRODUCTION Tobacco use has shifted increasingly from cigarettes to other products. While the focus has been mostly on cigarette-oriented policies, it is important to gauge the effects of policies targeting other products. We review and critique the literature on how policies affect smokeless tobacco (ST). METHODS We conducted a search of the literature on tobacco control policies as they relate to ST use, focusing on tobacco taxes, smoke-free air laws, media campaigns, advertising restrictions, health warnings, cessation treatment policies, and youth access policies. Findings from 78 total studies are summarized. RESULTS ST taxes, media campaigns, health warnings, and cessation treatment policies were found to be effective tools in reducing ST use. Evidence on the effects of current youth access policies is less strong. Studies have not yet been conducted on marketing or product content restrictions, but the literature indicates that product marketing, through advertising, packaging, flavorings, and extension of cigarette brands, plays an important role in ST use. CONCLUSIONS Although the evidence base is less established for ST policies than for cigarette policies, the existing literature indicates ST use responds to tobacco control policies. Policies should be structured in a way that aims to reduce all tobacco use while at the same time increasing the likelihood that continuing tobacco users use the least risky products. IMPLICATIONS Studies find that policies targeting smoking and policies targeting smokeless products affect smokeless use, but studies are needed to examine the effect of policies on the transitions between cigarette and smokeless use.

Abstract
INTRODUCTION Tobacco use prevalence has been commonly estimated on a product by product basis and the extent of polytobacco use among current users of each tobacco product is not well understood. This study aimed to examine the prevalence, trends, and correlates of polytobacco use among current users of cigarettes, cigars, chewing tobacco, and snuff in US adults aged ≥18. METHODS We used pooled data from the 1998, 2000, 2005, and 2010 Cancer Control Supplements of the National Health Interview Survey (N = 123 399 adults). Multivariate logistic regression models were estimated to determine significant factors associated with polytobacco use. RESULTS In 2010, the prevalence of polytobacco use was 8.6% among current cigarette smokers, 50.3% among current cigar users, 54.8% among current chewing tobacco users, and 42.5% among current snuff users. After controlling for other covariates, gender and race/ethnicity did not show consistent associations with poly-use across these four groups of current tobacco users; however, a positive association of young adulthood, less than high school education, and binge drinking with poly-use was consistently found among all these groups. CONCLUSIONS Polytobacco use is extremely popular among current users of non-cigarette tobacco products. Polytobacco use patterns differ across sociodemographic subpopulations, and the gender and racial/ethnic profiles in poly-users vary across different groups of current tobacco users. Tobacco control strategies need to consider the interrelationships in the use of different tobacco products and the diverse profiles of poly-users in order to develop tailored tobacco prevention and intervention policies to further reduce the burden of tobacco use.

Abstract
INTRODUCTION To date, there have been no large-scale, national epidemiological studies of tobacco use patterns among firefighters, particularly with a focus on smokeless tobacco (SLT) and dual use with cigarettes. While rates of firefighters' smoking are relatively low compared to the general population, SLT use typically is substantially higher than the populations they protect. In the current study, we systemically examine tobacco use, including SLT and dual use, and the health-related profiles of various tobacco use groups in a national sample of career firefighters. METHODS Data are from a national cohort study of career departments (N = 20) comprised of 947 male firefighters. RESULTS Among 947 participants, 197 (21%) were tobacco users, of which, 34.5% used cigarettes, 53.2% used SLT, and 12.2% used both cigarettes and SLT. Adjusted rates of smoking, SLT use, and dual use were 13.2%, 10.5%, and 12.2%, respectively. Tobacco users of all types were significantly younger and had served fewer years in fire service and were significantly more likely to engage in heavy and binge drinking, as well as more likely to show signs of depressive symptoms compared to nontobacco users. CONCLUSIONS Detailed information on tobacco use pattern will aid in better understanding what factors are contributing to the high rates of SLT and dual use among firefighters in order to guide and develop an appropriate treatment program for the fire service.

Abstract
With the declining sales of cigarettes, the tobacco industry has been promoting other forms of combustible and smokeless tobacco to current and former cigarette smokers. Exposure to the promotion of tobacco products has been shown to vary by income level. We combined the 2006 through 2011 National Surveys on Drug Use and Health to compare the prevalence and patterns of other tobacco use (cigar, snuff, and chewing tobacco) between current and former cigarette smokers by income level. Other tobacco use was minimal among females and among male non-smokers. Approximately a third of both current and former male cigarette smokers reported past-year other tobacco use. Overall, current smokers were more likely than former smokers to have used cigars (adjusted odds ratio (AOR) 1.69, 95% CI 1.50-1.92) or snuff (AOR 1.14, 95% CI 1.01-1.28) in the past year. The association of smoking status with other tobacco use differed by income level (interaction term p-value<0.001). Among lower income groups, current smokers were more likely to use cigars and snuff compared to former smokers. Among the highest income group, former smokers were just as likely to use smokeless tobacco as current smokers. The differing patterns of use of other tobacco between current and former smokers by income level highlight a need for studies to understand the motivations for the use of these products and their role in smoking cessation.

Abstract
INTRODUCTION Poly-tobacco use is defined as cigarette and other tobacco consumption with either product used daily or nondaily. While concurrent use of different types of tobacco has been documented within the general population, less is known about poly-tobacco use among HIV-positive smokers and its impact on smoking cessation efforts. OBJECTIVE To characterize the profile of poly-tobacco users (PTU) in a sample of HIV-positive smokers participating in a cessation program. METHODS The study sample consisted of 474 HIV-positive smokers enrolled in a 2-group randomized controlled trial of cigarette smoking cessation comparing a cell phone-based intervention to usual care. Prevalence was determined, and risk factors for poly-tobacco use were evaluated using logistic regression. RESULTS In this cohort of HIV-positive cigarette smokers, 21.6% of participants were PTU, with cigars (73.4%) the most common tobacco product consumed. Among PTU, 73.5% used other form(s) of tobacco some days, and 26.5% use them every day. Perceived discrimination and unemployment were significantly associated with poly-tobacco use after adjusting for other demographic, behavioral, and psychosocial factors. Analysis showed that participants in the cell phone group (vs. usual care) were more likely to report 24-hr abstinence, both among monocigarette users (16.6% vs. 6.3%, p < .001) and PTU (18.5% vs. 0%, p < .001). CONCLUSION Poly-tobacco use prevalence among adult HIV-positive smokers was considerably higher than in the general population. Special attention must be placed on concurrent use of cigarettes and cigars among HIV-positive smokers. Because PTU are a unique population less likely to succeed in brief smoking cessation interventions, effective cessation programs are needed.

Abstract
Little is known about smokeless tobacco (SLT) use in the fire service, whose personnel need to maintain high levels of health and fitness given the rigorous physical and mental job requirements. We examined the relationships among variables associated with SLT use and dual tobacco use (SLT and smoking) among 353 male career firefighters. Around 13% of male career firefighters reported being current exclusive SLT users, and 2.6% used both cigarettes and SLT. Age-adjusted models revealed that race, binge drinking, and dietary fat consumption were positively associated with exclusive SLT use when compared to nontobacco users. SLT users were much more likely to binge drink (OR = 3.98, P < .01) and consume high fat foods (OR = 1.94, P < .05). Only high dietary fat consumption was a strong correlate (OR = 8.41, P < .05) of dual use when compared to nontobacco users. SLT and dual tobacco use are associated with significant health risks. Detailed information on the predictors of SLT use among firefighters will aid in developing more effective tobacco prevention and cessation intervention in fire service.

Abstract
INTRODUCTION The tobacco industry has promoted the use of smokeless tobacco (SLT) to smokers as a substitution for cigarettes when smoking is not possible, and some smokers are using SLT this way. However, few publications have examined recent trends in dual cigarette and SLT use (dual use) over time in the U.S. MATERIALS AND METHODS We examined trends in the use of SLT among current, former and never cigarette smokers using data on adult (aged 18+ years) males (n=16,590) from the 1996-2008 Alaska Behavioral Risk Factor Surveillance System (BRFSS). We also examined trends from 2004 to 2008 in cigarette consumption among dual users. RESULTS Between 1996 and 2008, the overall prevalence of current SLT use and prevalence of current smoking among Alaskan men did not significantly change over time (p-value from age-adjusted models p=.63, p=.09, respectively). When we examined trends in SLT use by smoking status, we found that the prevalence of current SLT use remained unchanged between 1996 and 2008 among former and never smokers, but almost doubled among current smokers (age-adjusted p=.004). Between 2004 and 2008, cigarette consumption remained steady among current smokers who did not use SLT, but significantly decreased among dual users (age-adjusted p<.001). CONCLUSIONS Our findings suggest that male smokers in Alaska are increasingly likely to use SLT, but do not appear to be switching to SLT use exclusively. We recommend that other state tobacco control programs examine trends in dual use to confirm our findings, and for programs to continue encouraging cessation of all tobacco products.

Abstract
BACKGROUND The current study describes concurrent use of cigarettes and smokeless tobacco (CiST) among males and females and evaluates factors associated with CiST use. METHODS Cross-sectional data were drawn from the 2010 Behavioral Risk Factor Surveillance System (BRFSS). Weighted stratified analyses were performed to find associations between CiST use and sociodemographic factors by gender. CiST users were compared to three different tobacco use groups: nonusers, exclusive smokers, and exclusive ST users. RESULTS Younger age and heavy alcohol consumption were consistently associated with increased odds of CiST use among both males and females, and regardless of comparison group. Among males, education was inversely related to CiST use, and these findings were consistent in all three comparisons. Among women, those unable to work or out of work were more likely to be CiST users, which was consistent across comparisons. American Indian females had higher odds of CiST use than White females when nontobacco users or smokers were the comparison group. CONCLUSION This study identified sociodemographic characteristics associated with CiST use, and differences in these associations among women and men. Additionally, this study highlights the need to carefully consider what comparison groups should be used to examine factors associated with CiST use.

Concurrent use of cigarettes and smokeless tobacco in Minnesota. JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2012; 2012:493109.

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

Abstract
A wide variety of non-cigarette forms of tobacco and nicotine exist, and their use varies regionally and globally. Smoked forms of tobacco such as cigars, bidis, kreteks and waterpipes have high popularity and are often perceived erroneously as less hazardous than cigarettes, when in fact their health burden is similar. Smokeless tobacco products vary widely around the world in form and the health hazards they present, with some clearly toxic forms (eg, in South Asia) and some forms with far fewer hazards (eg, in Sweden). Nicotine delivery systems not directly reliant on tobacco are also emerging (eg, electronic nicotine delivery systems). The presence of such products presents challenges and opportunities for public health. Future regulatory actions such as expansion of smoke-free environments, product health warnings and taxation may serve to increase or decrease the use of non-cigarette forms of tobacco. These regulations may also bring about changes in non-cigarette tobacco products themselves that could impact public health by affecting attractiveness and/or toxicity.

Abstract
INTRODUCTION Concomitant use of two forms of tobacco is an increasing public health concern, yet there is little consensus regarding a consistent definition of so-called "dual use." We defined dual use as cigarette and smokeless tobacco (ST) consumption with either product used daily or nondaily. METHODS We analyzed a cohort of 36,013 Air Force recruits. We categorized dual tobacco use across 2 dimensions, type of tobacco products (cigarettes, ST, or others), and the frequency of use (daily vs. nondaily). We determined how varying the definition impacted the prevalence estimates and evaluated the prevalence estimate based on our recommended definition of dual use. Multivariate logistic regression analysis was used to evaluate the risk profile of dual users of ST and cigarettes versus mono users of ST and mono users of cigarettes. RESULTS Varying definitions of dual use vary prevalence estimates 50-fold (0.5%-25.3%). Including only ST and cigarettes narrows the prevalence estimate to less than 4-fold (2.0%-9.7%). Dual users are more likely to be young Caucasian males, with lower education, and from families with relatively higher incomes. Compared with mono users, dual users of cigarettes and ST have a distinct pattern of risk profiles. CONCLUSIONS Depending on the definition of dual use, markedly different prevalence and risk profiles are observed. Dual users of ST and cigarettes are a unique group of tobacco users. We propose a common definition of dual use to advance our understanding of this unique group.

Abstract
Tobacco use continues to be the leading preventable cause of premature death in the United States, killing over 430,000 people annually. Tobacco initiation and use among youth remains a significant public health concern. Despite declines in U.S. youth tobacco use in recent years, state and national survey results are still cause for alarm. Although traditional school-based curricular programs are the most common strategy to prevent or reduce youth tobacco use, their effectiveness may be limited because young people are immersed in a broader social context in which tobacco is readily available. Environmental strategies change this social context by focusing on policy, enforcement, and media. A compelling body of evidence suggests that interventions at the state and federal levels can, when implemented in combination, reduce youth tobacco use. The impact of policies implemented at the local levels is less well understood and effects of environmental strategies on smokeless tobacco consumption have been largely ignored. The purpose of this paper is to review the literature on environmental strategies implemented at the local level on youth use of both cigarettes and smokeless tobacco. We highlight results of the extant literature, hypothesize possible effects where research is lacking, and suggest where future studies might be warranted.

Abstract
BACKGROUND In the USA, consumption of moist snuff continues to increase and cigarette manufacturers now control nearly its entire market. Manufacturers have developed new products that represent cigarette brand extension and in test marketing are promoting dual use of cigarettes and snuff. This study examined patterns of concurrent use of smokeless tobacco (ST) and cigarettes among young people and adults in the USA just before cigarette companies' control of the nation's ST market. METHODS Data were drawn from four US nationally representative surveys. Stratified analyses applied sampling weights and accounted for the complex sample designs. RESULTS Cigarette smoking was substantially more prevalent among young males who used ST than among those who did not. Among adult males, those who smoked daily were less likely than others to have used snuff every day. Men who used moist snuff daily had the lowest prevalence of daily smoking, but the prevalence of daily smoking was relatively high among men who used moist snuff less than daily. Unsuccessful past-year attempts by daily smokers to quit smoking were more prevalent among non-daily snuff users (41.2%) than among those who had never used snuff (29.6%). CONCLUSIONS Although dual daily use of ST and cigarettes is relatively uncommon in the USA, concurrent ST use is more common among adolescent and young adult male smokers than among more mature tobacco users. Among adult males, daily smoking predominates and non-daily ST use is very strongly associated with current smoking. Adult male smokers who also use ST daily tend to have relatively high levels of serum cotinine and high prevalence of a major indicator for tobacco dependence.

Abstract
BACKGROUND The primary focus of tobacco prevention and cessation interventions has been on cigarette smoking. Polytobacco use (the concurrent use of cigarettes and one or more other tobacco product[s]), may present additional health risks and make cessation more difficult. METHODS We determined population estimates of tobacco product use and of polytobacco use for more than 50000 adults from 10 states. Logistic regression analyses were used to determine factors independently associated with polytobacco use among men only (due to low use among women). RESULTS The overall adult prevalence was 22.4% for cigarettes and 3.4% for polytobacco use. Polytobacco use was more common among men who smoked cigarettes, with 26.0% using at least one other product, compared to 4.4% of women cigarette smokers. Polytobacco use among men was significantly associated with younger age, all races/ethnicities except Hispanic, less educational attainment, less income, and more-than-moderate alcohol use. CONCLUSIONS Prevention and cessation efforts need to target use of other forms of tobacco besides cigarettes, especially among younger men and men who are more-than-moderate drinkers of alcohol.

Abstract
UNLABELLED The literature on concurrent tobacco (CCT) use, i.e., regularly using both smoked and chewed tobacco, is sparse. OBJECTIVES This study aims to establish the point prevalence of CCT use in a randomly selected sample of UK-resident Bangladeshi males, compare CCT users with other tobacco users (smokers alone and chewers alone), and model the factors for CCT use and chewing tobacco use alone. METHODS A cross-sectional bilingual interview survey collecting data on age, marital status, social class, employment status, home ownership and overcrowding, self-assessed health and chronic illness episodes, social capital, nicotine dependence, and oral pain was used. Carbon monoxide readings validated smoked tobacco use. Logistic regressions were used for data analysis. RESULTS The initial response rate was 59 percent. Sample mean age was 40.7 years. CCT prevalence was estimated at 22 percent, practiced by older respondents of limited educational status. CCT users more likely had only average or poor self-rated health and more likely reported current oral pain compared with tobacco smokers. A wife chewing tobacco distinguished CCT users, as compared with tobacco smokers alone. CONCLUSIONS In this sample of adult Bangladeshi males, CCT use was prevalent. CCT users more likely had a partner who was also a tobacco chewer, as compared with tobacco smokers.

Abstract
BACKGROUND As smoking prevalence declines in the United States, it is important to understand if smokeless tobacco (SLT) use is also changing and if so, among what groups. METHODS We examine the prevalence of SLT use and smoking, 1992-2002, using the Current Population Survey-Tobacco Use Supplements (CPS-TUS), which used US nationally representative samples based on stratified clusters of households. RESULTS Consistent with declines in smoking, the prevalence of current SLT use declined over the period 1992-2002 for males and females ages 18 and older. The overall separate declines in SLT use and in smoking are mirrored by a decline in concurrent use of SLT and cigarettes. SLT use is becoming more associated with white males, but use is declining faster among the youngest males. CONCLUSIONS The findings indicate that relative reductions in smoking prevalence are exceeded by relative reductions in SLT use, with sizeable reductions in concurrent use. These results suggest that the stricter cigarette policies of recent years may not only reduce cigarette use, but also the use of alternative tobacco products. In light of potential policy implications of SLT use as a potential reduced exposure product (PREP), current survey methods require more careful measurement of SLT use in terms of initiation, duration, quantity, and cessation.

Abstract
According to the Centers for Disease Control and Prevention, about 45 million Americans continue to smoke, even after one of the most intense public health campaigns in history, now over 40 years old. Each year some 438,000 smokers die from smoking-related diseases, including lung and other cancers, cardiovascular disorders and pulmonary diseases. Many smokers are unable--or at least unwilling--to achieve cessation through complete nicotine and tobacco abstinence; they continue smoking despite the very real and obvious adverse health consequences. Conventional smoking cessation policies and programs generally present smokers with two unpleasant alternatives: quit, or die. A third approach to smoking cessation, tobacco harm reduction, involves the use of alternative sources of nicotine, including modern smokeless tobacco products. A substantial body of research, much of it produced over the past decade, establishes the scientific and medical foundation for tobacco harm reduction using smokeless tobacco products. This report provides a description of traditional and modern smokeless tobacco products, and of the prevalence of their use in the United States and Sweden. It reviews the epidemiologic evidence for low health risks associated with smokeless use, both in absolute terms and in comparison to the much higher risks of smoking. The report also describes evidence that smokeless tobacco has served as an effective substitute for cigarettes among Swedish men, who consequently have among the lowest smoking-related mortality rates in the developed world. The report documents the fact that extensive misinformation about ST products is widely available from ostensibly reputable sources, including governmental health agencies and major health organizations. The American Council on Science and Health believes that strong support of tobacco harm reduction is fully consistent with its mission to promote sound science in regulation and in public policy, and to assist consumers in distinguishing real health threats from spurious health claims. As this report documents, there is a strong scientific and medical foundation for tobacco harm reduction, and it shows great potential as a public health strategy to help millions of smokers.
