Project description:There are an estimated 8 million users of smokeless tobacco products (STPs) in the United States, and yet limited data on microbial populations within these products exist. To better understand the potential microbiological risks associated with STP use, a study was conducted to provide a baseline microbiological profile of STPs. A total of 90 samples, representing 15 common STPs, were purchased in metropolitan areas in Little Rock, AR, and Washington, DC, in November 2012, March 2013, and July 2013. Bacterial populations were evaluated using culture, pyrosequencing, and denaturing gradient gel electrophoresis (DGGE). Moist-snuff products exhibited higher levels of bacteria (average of 1.05 × 106 CFU/g STP) and diversity of bacterial populations than snus (average of 8.33 × 101 CFU/g STP) and some chewing tobacco products (average of 2.54 × 105 CFU/g STP). The most common species identified by culturing were Bacillus pumilus, B. licheniformis, B. safensis, and B. subtilis, followed by members of the genera Oceanobacillus, Staphylococcus, and Tetragenococcus. Pyrosequencing analyses of the 16S rRNA genes identified the genera Tetragenococcus, Carnobacterium, Lactobacillus, Geobacillus, Bacillus, and Staphylococcus as the predominant taxa. Several species identified are of possible concern due to their potential to cause opportunistic infections and reported abilities to reduce nitrates to nitrites, which may be an important step in the formation of carcinogenic tobacco-specific N'-nitrosamines. This report provides a microbiological baseline to help fill knowledge gaps associated with microbiological risks of STPs and to inform potential regulations regarding manufacture and testing of STPs.ImportanceIt is estimated that there 8 million users of smokeless tobacco products (STPs) in the United States; however, there are limited data on microbial populations that exist within these products.

Project description:Background and objectivesNon-cigarette tobacco marketing is less regulated and may promote cigarette smoking among adolescents. We quantified receptivity to advertising for multiple tobacco products and hypothesized associations with susceptibility to cigarette smoking.MethodsWave 1 of the nationally representative PATH (Population Assessment of Tobacco and Health) study interviewed 10?751 adolescents who had never used tobacco. A stratified random selection of 5 advertisements for each of cigarettes, e-cigarettes, smokeless products, and cigars were shown from 959 recent tobacco advertisements. Aided recall was classified as low receptivity, and image-liking or favorite ad as higher receptivity. The main dependent variable was susceptibility to cigarette smoking.ResultsAmong US youth, 41% of 12 to 13 year olds and half of older adolescents were receptive to at least 1 tobacco advertisement. Across each age group, receptivity to advertising was highest for e-cigarettes (28%-33%) followed by cigarettes (22%-25%), smokeless tobacco (15%-21%), and cigars (8%-13%). E-cigarette ads shown on television had the highest recall. Among cigarette-susceptible adolescents, receptivity to e-cigarette advertising (39.7%; 95% confidence interval [CI]: 37.9%-41.6%) was higher than for cigarette advertising (31.7%; 95% CI: 29.9%-33.6%). Receptivity to advertising for each tobacco product was associated with increased susceptibility to cigarette smoking, with no significant difference across products (similar odds for both cigarette and e-cigarette advertising; adjusted odds ratio = 1.22; 95% CI: 1.09-1.37).ConclusionsA large proportion of US adolescent never tobacco users are receptive to tobacco advertising, with television advertising for e-cigarettes having the highest recall. Receptivity to advertising for each non-cigarette tobacco product was associated with susceptibility to smoke cigarettes.

Project description:OBJECTIVE:To systematically review the price elasticity of demand of non-cigarette tobacco products. DATA SOURCES:Medline, Embase, EconLit and the Web of Science without language or time restrictions. STUDY SELECTION:Two reviewers screened title and abstracts, then full texts, independently and in duplicate. We based eligibility criteria on study design (interventional or observational), population (individuals or communities without geographic restrictions), intervention (price change) and outcome (change in demand). DATA EXTRACTION:We abstracted data on study features, outcome measures, statistical approach, and single best own- and cross-price elasticity estimates with respect to cigarettes. We conducted a random effects meta-analysis for estimates of similar product, outcome and country income level. For other studies we reported median elasticities by product and country income level. DATA SYNTHESIS:We analysed 36 studies from 15 countries yielding 125 elasticity estimates. A 10% price increase would reduce demand by: 8.3% for cigars (95%?CI 2.9 to 13.8), 6.4% for roll your owns (95% CI 4.3 to 8.4), 5.7% for bidis (95% CI 4.3 to 7.1) and 2.1% for smokeless tobacco (95% CI -0.6 to 4.8). Median price elasticities for all ten products were also negative. Results from few studies that examined cross-price elasticity suggested a positive substitution effect between cigarette and non-cigarette tobacco products. CONCLUSIONS:There is sufficient evidence in support of the effectiveness of price increases to reduce consumption of non-cigarette tobacco products as it is for cigarettes. Positive substitutability between cigarette and non-cigarette tobacco products suggest that tax and price increases need to be simultaneous and comparable across all tobacco products.

Project description:IntroductionSmokeless tobacco products such as snuff and snus are used worldwide. However, little is known about the systemic and cardiovascular toxicity of smokeless tobacco exposure.MethodsBiomarkers of endothelial activation and injury, immune functions, platelet activation and insulin resistance were measured in 8-week old male C57BL/6 mice exposed to commercial snuff, CRP-2 reference snuff, commercial snus, CRP-1 reference snus, and nicotine in drinking water (100 µg/mL) for 4, 12, and 24 weeks.ResultsTwenty-four weeks of exposure to smokeless tobacco products or nicotine significantly decreased the levels of circulating Flk+/Sca+ endothelial progenitor cells. Twelve and 24 weeks of exposure to all the smokeless tobacco products and nicotine significantly decreased the levels of circulating CD19+ B cells, CD4+ T cells, CD8+ T cells, and CD11b+ monocytes, whereas 4 weeks of exposure to Camel snus and Copenhagen snuff significantly depleted the levels of peripheral blood CD19+ B cells and CD11b+ monocytes. Twenty-four weeks of exposure to smokeless tobacco products or nicotine significantly decreased plasma IFNγ levels. However, plasma TNFα levels were significantly increased in mice exposed to Copenhagen snuff or nicotine for 24 weeks. This was accompanied by a five to sevenfold increase in the hepatic expression of TNFα. Neither smokeless products nor nicotine affected plasma lipoproteins, platelet activation, or systemic insulin sensitivity.ConclusionsChronic exposure to snuff and snus suppresses circulating levels of EPCs, endothelial microparticles and immune cells, but increases plasma TNF-α levels. These effects of smokeless tobacco products are attributable, at least in part, to nicotine.ImplicationsExposure to smokeless tobacco products results in the depletion of endothelial progenitor cells, which may impair the endothelium repair. Suppression of the circulating levels of immune cells upon exposure to smokeless tobacco products may increase the susceptibility to secondary infection. Increased formation of proinflammatory cytokines such as TNFα by nicotine or Copenhagen snuff may lead to vascular inflammation and thereby exacerbate atherogenesis.

Project description:Tobacco-specific nitrosamines (TSNAs) have been of concern to the public health community for decades and their reduction through agricultural practices, plant breeding, and tobacco processing has also been a decades-long industry effort. Despite those efforts, TSNAs, though lower, continue to be constituents of concern in tobacco products. This paper examines the TSNA levels of dark air-cured, dark fire-cured, and burley tobaccos purchased in the United States by U.S. Smokeless Tobacco Company LLC (USSTC) and of nine finished USSTC moist smokeless tobacco products. TSNA values of the incoming purchased tobaccos and the finished products showed considerable variability. For the incoming tobaccos, the coefficient of variation was generally more than 100 % for each tobacco type and for each of the measured TSNAs. The relative TSNA variability of the finished tobacco products was also considerable, averaging approximately 25 %. It was also found that the measured values for the finished products averaged well above the proposed FDA NNN proposed product standard of 1.0 ?g/g dry weight. Because of the large variability in NNN values, products would have to average well below FDA's proposed product standard to be consistently compliant.

Project description:IntroductionThe smokeless tobacco (SLT) industry in the U.S. continues to transform with novel products amid an evolving regulatory environment. We report SLT sales trends in the U.S. by analyzing retail market scanner data from 2011 through 2019.MethodsNational SLT sales data were obtained from Nielsen's Convenience Track System for January 2011 to December 2019. UPC codes were used to classify products by attributes including type, parent company, brand, form, and flavor. Market share was calculated as percentage of total unit sales. Detailed product analysis was presented for moist snuff, snus, and tobacco-free nicotine products.ResultsSLT sales increased by 5.8% between 2011 and 2016 but declined by 3.9% from 2016 to 2019. Moist snuff sales increased by 8.1% between 2011 and 2016 and then declined 7.4% from 2016 to 2019 but still accounted for roughly 90% of the overall market annually. Between 2011 and 2019, snus sales consistently increased while sales of chew, dry snuff, and dissolvables decreased. Tobacco-free nicotine products emerged in 2016 and captured 4.0% of the market by 2019. Portion pouch packaging and flavors showed consistent growth although their popularity varied by the type of smokeless product.ConclusionThis study extends our previous work on U.S. SLT market trends through 2019. Overall sales increased between 2011 and 2016 but there were signs of leveling off including declining sales of moist snuff. Newer products continue to gain market share. Continued monitoring of SLT sales is needed, particularly given the new modified risk status of several products.ImplicationsThis study analyzed the last 9 years of smokeless tobacco market data (2011-2019) to describe recent trends in sales. Overall, the smokeless product category is quite resilient although signs suggest downward trends among some product categories and features. New types of smokeless tobacco products (eg, snus and tobacco-free nicotine pouches) account for a growing share of the market.

Project description:IntroductionWe examined the potential impact of COVID-19 on trends in volume sales of non-cigarette combustible and smokeless tobacco products in the United States.Aims and methodsWe analyzed monthly national sales for cigars, smokeless tobacco, pipe, and roll-your-own tobacco during June 2019-June 2021. Data were from the U.S Department of the Treasury. Interrupted time-series were used to measure associations of the COVID-19 "shock" (taken as June 2020 or 6 months after the first diagnosis of COVID-19 in the United States) and volume sales. Negative binomial regression was used to evaluate associations between volume sales and changes in community mobility.ResultsWithin interrupted time-series analysis, the shock of the COVID-19 pandemic was associated with an initial increase in the number of little cigars sold by 11.43 million sticks (p < .01), with no significant sustained change in trend. The COVID-19 shock was also associated with an initial increase in large cigar volume sales by 59.02 million sticks, followed by a subsequent decrease by 32.57 million sticks per month (p = .005). Every 10% reduction in mobility to retail stores was significantly associated with reduced volume sales of little cigars (IRR = 0.84, 95% CI, 0.71 to 0.98) and large cigars (IRR = 0.92, 95% CI, 0.88 to 0.96). Other findings were statistically nonsignificant.ConclusionsCOVID-19 was associated with increased volume sales for cigars and there was a significant association between reduced mobility to points of sale and reduced cigar volume sales. Intensified efforts are needed to prioritize evidence-based tobacco prevention and control efforts amidst the pandemic.

Project description:IntroductionA previous Minnesota SimSmoke tobacco control policy model is extended to more recent years and to include smokeless tobacco use.MethodsUsing data from the 1993 Tobacco Use Supplement and information on state policies, the Minnesota SimSmoke model was updated and extended to incorporate smokeless tobacco (both exclusive and dual use) and smokeless tobacco-attributable deaths. The model was then validated against the 2002, 2006/2007, and 2014/2015 Tobacco Use Supplement and the 1999, 2007, 2014, and 2018 Minnesota Adult Tobacco Survey and used to estimate the impact of policies implemented between 1993 and 2018. Analysis was conducted in April 2019.ResultsThe model validated well for cigarette and earlier smokeless tobacco use, but it predicted smokeless tobacco use less well in recent years. The model projected that male (female) smoking prevalence was 35% (36%) lower in relative terms by 2018 and 43% (44%) lower by 2040 owing to policies, with lesser reductions projected for male smokeless tobacco use. Tobacco-attributable deaths were reduced by 7,800 by 2018 and 46,900 by 2040. Price increases, primarily through taxes, were projected to have had the greatest impact on cigarette use followed by smoke-free air laws, cessation treatment policies, tobacco control campaign expenditures, and youth access enforcement. Similar effects were projected for smokeless tobacco use, except that smoke-free air laws had smaller effects.ConclusionsAs cigarettes remain the dominant form of nicotine delivery product, cigarette-oriented policies may be an effective means of reducing the use of all nicotine delivery products. However, noncigarette-oriented policies may also play an important role.

Project description:ObjectivesCompare cigarette and smokeless tobacco (ST) perceptions within a youth population where ST use is common.MethodsMale baseball players (N = 594) at 36 rural high schools in California rated separately 20 potential risks or benefits associated with cigarettes or ST, along with global harm ratings. Informed by principal components analysis, 3 composite categories were created: oral/rule-breaking risks (eg, mouth cancer, getting in trouble), systemic risks (eg, heart attack), and benefits (eg, relaxation). Standardized composite scores and harm ratings were compared by product and by tobacco use status.ResultsCigarettes were perceived as likely to impart oral/rule-breaking risks and systemic risks, unlikely to cause benefits, and as very harmful overall. ST was perceived similarly as cigarettes regarding oral/rule-breaking risks, but less likely to cause systemic risks, and more beneficial. Most participants rated cigarettes as more harmful than ST. Similar patterns existed in all tobacco use groups, including non-users and dual-users.ConclusionsIn this population, cigarettes were perceived as very harmful. ST was perceived similarly to cigarettes only for some risks and as less harmful overall. Communication for rural adolescents should consider multifaceted aspects of ST risk.

Project description:IntroductionMonitoring the activities and impacts of tobacco industries is vital for tobacco control. Based on tobacco industry financial statements and a nationally representative survey of Korean adolescents, we examined the association between tobacco industry commercial advertising expenses and advertising exposure among Korean adolescents.MethodsThe commercial advertising expenses of three major tobacco industries in Korea (KT&G, Philip Morris Korea, and British and American Tobacco Korea) were identified in a repository (Data Analysis Retrieval and Transfer System) established by the Korean Financial Supervisory Service. The yearly advertising expenses were merged with data from the Korean Youth Risk Behavior Survey (2015-2018 and 2021, total N=309 190). We used logistic regression analyses to analyse the associations between tobacco industry advertising expenses and adolescent tobacco advertisement exposure.ResultsIn 2021, the total advertising expenses of the three companies exceeded US$260 million, and the proportion of Korean adolescents exposed to tobacco advertisements ranged from 65.9% to 78.7% during 2015-2018 and 2021. Higher advertising expense sizes were associated with the risk of exposure to tobacco advertisements in both girls and boys, with OR of 1.009 (95% CI (1): 1.008 to 1.010) and 1.010 (95% CI: 1.009 to 1.011), respectively.ConclusionTobacco industry advertising expenses are associated with tobacco marketing exposure among adolescents. We used financial data to identify the reach of tobacco advertising among Korean adolescents. It is essential to increase tobacco industry surveillance using various data sources and to regulate tobacco advertising more strongly.
