Project description:BackgroundCigarette smoking is associated with an increase in cardiovascular disease risk, attributable in part to reactive volatile organic chemicals (VOCs). However, little is known about the extent of VOC exposure due to the use of other tobacco products.MethodsWe recruited 48 healthy, tobacco users in four groups: cigarette, smokeless tobacco, occasional users of first generation e-cigarette and e-cigarette menthol and 12 healthy nontobacco users. After abstaining for 48 h, tobacco users used an assigned product. Urine was collected at baseline followed by five collections over a 3-h period to measure urinary metabolites of VOCs, nicotine, and tobacco alkaloids.ResultsUrinary levels of nicotine were ≃2-fold lower in occasional e-cigarette and smokeless tobacco users than in the cigarette smokers; cotinine and 3-hydroxycotinine levels were similar in all groups. Compared with nontobacco users, e-cigarette users had higher levels of urinary metabolites of xylene, cyanide, styrene, ethylbenzene, and benzene at baseline and elevated urinary levels of metabolites of xylene, N,N-dimethylformamide, and acrylonitrile after e-cigarette use. Metabolites of acrolein, crotonaldehyde, and 1,3-butadiene were significantly higher in smokers than in users of other products or nontobacco users. VOC metabolite levels in smokeless tobacco group were comparable to those found in nonusers with the exception of xylene metabolite-2-methylhippuric acid (2MHA), which was almost three fold higher than in nontobacco users.ConclusionsSmoking results in exposure to a range of VOCs at concentrations higher than those observed with other products, and first generation e-cigarette use is associated with elevated levels of N,N-dimethylformamide and xylene metabolites.ImplicationsThis study shows that occasional users of first generation e-cigarettes have lower levels of nicotine exposure than the users of combustible cigarettes. Compared with combustible cigarettes, e-cigarettes, and smokeless tobacco products deliver lower levels of most VOCs, with the exception of xylene, N,N-dimethylformamide, and acrylonitrile, whose metabolite levels were higher in the urine of e-cigarette users than nontobacco users. Absence of anatabine in the urine of e-cigarette users suggests that measuring urinary levels of this alkaloid may be useful in distinguishing between users of e-cigarettes and combustible cigarettes. However, these results have to be validated in a larger cohortcomprised of users of e-cigarettes of multiple brands.

Project description:Lying appears in everyday oral and written communication. As a consequence, detecting it on the basis of linguistic analysis is particularly important. Our study aimed to verify whether the differences between true and false statements in terms of complexity and sentiment that were reported in previous studies can be confirmed using tools dedicated to measuring those factors. Further, we investigated whether linguistic features that differentiate true and false utterances in English-namely utterance length, concreteness, and particular parts-of-speech-are also present in the Polish language. We analyzed nearly 1,500 true and false statements, half of which were transcripts while the other half were written statements. Our results show that false statements are less complex in terms of vocabulary, are more concise and concrete, and have more positive words and fewer negative words. We found no significant differences between spoken and written lies. Using this data, we built classifiers to automatically distinguish true from false utterances, achieving an accuracy of 60%. Our results provide a significant contribution to previous conclusions regarding linguistic deception indicators.

Project description:Introduction:While smoking rates have declined, use of smokeless tobacco (ST) has remained constant. ST is heavily marketed to cigarette smokers, and many ST users smoke cigarettes. This study provides updated comparisons of the characteristics, smoking behaviors, and perceptions of US adult dual ST and cigarette users and exclusive cigarette smokers in 2015-2016. Methods:Data were from nationally representative, cross-sectional surveys from 2015 and 2016. Adult smokers reported past 30-day use of ST, current cigarette smoking, risk perceptions, smoking, and quitting behaviors. We estimated Rao-Scott ?2 and adjusted odds ratios (AORs) to compare dual users and exclusive smokers. Results:Dual users were more likely to be younger, reside in nonmetropolitan statistical areas (MSA) and outside the Northeast United States. Adjusting for covariates, dual users did not differ significantly from exclusive smokers on most smoker characteristics, including number of past year quit attempts. Dual users were more likely to report past 30-day use of novel tobacco products (AORs 2.90 [little cigars and cigarillos] to 11.02 [hookah]). Dual users who reported at least 1 past year cigarette quit attempt were more likely than exclusive smokers to report using ST, traditional cigars, hookah, or heat-not-burn as a past year quit method (AOR: 9.54 [95% CI: 3.22 to 28.23]). Conclusions:Smokers who use ST are more likely than exclusive smokers to attempt to quit smoking cigarettes using other tobacco products. These findings may be attributed to increasing use prevalence of novel products. We recommend further monitoring to assess polytobacco use and differences among these populations. Implications:Many current ST users smoke cigarettes and ST promotions often target cigarette smokers. As the FDA considers ST regulations and implements a nicotine centered regulatory framework, it is imperative to evaluate how these policies and promotion of ST as potentially reduced risk products impact dual and polytobacco use. Our study found that many dual users engage in novel tobacco use in general and as a cessation method. Consideration of ST and polytobacco use among smokers may be helpful in the development of forthcoming FDA regulations, messaging, and interventions.

Project description:Epidemiological and toxicological evidence suggests lower risk of smokeless tobacco (ST) products compared to cigarettes. Less is known, however, about consumer perceptions and use of novel forms of ST, including snus and dissolvable tobacco.In this study, we conducted in-person experimental auctions in Buffalo, NY, Columbia, SC, and Selinsgrove, PA with 571 smokers to test the impact of information and product trials on smokers' preferences. Auctions were conducted between November 2010-November 2011.We found no evidence of an impact of product trials on demand in our auctions. Anti-ST information increased demand for cigarettes when presented alone, but when presented with pro-ST information it decreased demand for cigarettes. It did not decrease demand for ST products. Anti-smoking information increased demand for ST products, but did not affect cigarette demand.These findings suggest that credible and effective communications about tobacco harm reduction should reinforce the negative effects of smoking.

Project description:IntroductionBased on arguments for harm reduction and health benefits, tobacco companies in the United States can apply for regulatory authorization to make "modified risk tobacco product" (MRTP) marketing claims. The impact of future MRTP claims may depend on whether they are noticed, believed, and lead to smokers switching products. This study provides baseline data about smokers' exposure to perceived MRTP claims ahead of any MRTP authorizations.Aims and methodsWe analyzed measures from Wave 3 of the US-based Population Assessment of Tobacco and Health (PATH) study which asked smokers to indicate if they had seen any e-cigarettes, snus, or other smokeless tobacco (SLT) products that claim to be "less harmful" in the past 12 months, and their likelihood of using products with these claims in the next 30 days.ResultsSignificantly fewer smokers noted having seen snus (5.1%) or other SLT (5.6%) with "less harmful" claims compared with e-cigarettes (29.1%). For each product, the prevalence of MRTP claim exposure was higher among smokers who perceived the product to be less harmful than smoking, who currently used the product, and who had higher rates of tobacco advertising exposure at the point of sale. Among smokers who noticed products with "less harmful" claims, about one-quarter said they would use them in the future (24%-27%).ConclusionsAhead of any Food & Drug Administration (FDA) authorization for MRTP claims, some smokers already perceive exposure to "less harmful" claims for e-cigarettes, but few do for SLT. MRTP claims may motivate some smokers to use these products.ImplicationsThis study provides new baseline data about smokers' perceived exposure to MRTP claims in the United States ahead of any regulatory claim authorization. Using data from Wave 3 of the US PATH study, we found that some smokers already perceive exposure to "less harmful" claims for e-cigarettes (29%), but few do for SLT (5%-6%). Among smokers who noticed products with "less harmful" claims, about one-quarter said they would use them in the future (24%-27%), suggesting MRTP claims may motivate some smokers to use products described as "less harmful."

Project description:RationaleOral tobacco-derived nicotine products include on!® nicotine pouches (NPs) which are tobacco-leaf free and available in multiple flavors and nicotine levels. Switching completely to NPs from cigarettes and moist smokeless tobacco (MST) has the potential to reduce harm for adult tobacco consumers. However, the dependence potential of NPs is not established. Therefore, we characterized the abuse potential of NPs with different nicotine levels compared to cigarettes and MST.ObjectivesTo evaluate nicotine pharmacokinetics (PK) and subjective effects of NPs (ranging from 1.5 to 8 mg nicotine) compared to own brand cigarettes (OBCs) and MST (OBMST).MethodsWe used a randomized, in-clinic, partial single-blind, 7-way crossover design to assess nicotine PK and subjective effects in dual users of cigarettes and MST.ResultsThe mean nicotine Cmax for NPs increased with nicotine level, ranging from 3.5 ng/mL (1.5 mg NP) to 15.4 ng/mL (8 mg NP), compared with 12.2 ng/mL for OBCs and 9.8 ng/mL for OBMST. Nicotine tmax was much longer for all NPs and OBMST (32.5-34.4 min) compared to OBCs (8.5 min). Reductions in urges to smoke after use of the 2 mg, 3.5 mg, and 8 mg NPs were not statistically different (p > 0.05) relative to OBC. Also, NPs resulted in lower ratings of positive subjective effects relative to OBCs and OBMST.ConclusionsOverall, based on the study results and literature reported nicotine PK values for cigarettes and MST, the abuse potential of NPs is not likely to be higher than OBCs and OBMST. NPs may be potentially acceptable switching products for users of cigarettes and MST products.

Project description:In this study, we investigate voters' unaided perceptions of whether politicians are lying. We conduct an experiment in which participants attempt to uncover politicians' dishonesty by watching videos of their speeches. We find that verbal cues (specifically, the amount of detail in the speech) and general demeanor cues explain the success (failure) of veracity judgments far better than paraverbal and nonverbal cues. We also find evidence of a truth bias-people are more likely to judge statements to be true than false-despite the political setting, where voters might have been more skeptical. However, gender plays a deterministic role for veracity judgments in political context; female politicians are more likely to be judged as honest.

Project description:BackgroundCigarettes and smokeless tobacco (SLT) products are among a wide range of tobacco products that are addictive and pose a significant health risk. In this study, we estimated smoking- and SLT use-related mortality hazard ratios (HRs) among U.S. adults by sex, age group, and cause of death, for nine mutually exclusive categories of smoking and/or SLT use.MethodsWe used data from the public-use National Health Interview Survey Linked Mortality with mortality follow-up through 2015. We used Cox proportional hazard models to estimate mortality HRs, adjusted by race/ethnicity, education, poverty level, body mass index, and tobacco-use status.ResultsWith never users as reference group, HRs for smoking-related diseases for male exclusive current smokers aged 35-64 and 65+ were 2.18 (95% confidence interval [CI]: 1.79-2.65), and 2.45 (95% CI: 2.14-2.79), respectively. Similar significant HR estimates were found for females and for all-cause mortality (ACM) and other-cause mortality (OCM) outcomes. HRs for exclusive current SLT users were only significant for males aged 35-64 for ACM (HR: 2.04, 95% CI: 1.27-3.27) and OCM (HR: 2.80, 95% CI: 1.50-5.25). HRs for users who switched from cigarettes to SLT products were significant for males aged 65+ for smoking-related diseases (HR: 2.06, 95% CI: 1.47-2.88), SLT-related diseases (HR: 1.99, 95% CI: 1.36-2.89), and ACM (HR: 1.63, 95% CI: 1.21-2.19).ConclusionsMale exclusive current SLT users aged 35-64 had a significant HR for ACM and OCM outcomes, suggesting that deaths not attributed to SLT use could be contributing to the ACM elevated HR for exclusive current SLT users.

Project description:Objectives: Compare the brand availability, pricing and presence of illicit products in semi-urban and rural areas in India across product types and states. Methods: In late 2017, 382 unique tobacco products were purchased from localities with populations under 50,000 in the states of Assam, Karnataka, Maharashtra, Rajasthan, and Uttar Pradesh. Brand, printed maximum retail price, price paid, tax, and health warning labels (HWLs) were used to compare the market for bidis, smokeless tobacco (SLT), and cigarettes. Results: Brand availability and pricing of SLT products was similar to cigarettes. Brand availability and pricing of bidis was consistent with having many small producers. Bidis and single serving SLT with spice mixtures were more affordable than cigarettes and SLT sold alone. 2% of SLT and 10% of cigarettes did not feature an India HWL. Conclusion: The elimination of single serving SLT packets and the removal of tax exemptions for small producers, often exploited by bidi producers, could reduce their respective affordability. State differences in illegal and illicit products could indicate a greater need for enforcement in some states.

Project description:Smokeless tobacco products (STP) contain diverse microbial communities that contribute to the formation of harmful chemical byproducts. This is concerning since 300 million individuals around the globe are users of smokeless tobacco. Significant evidence has shown that microbial metabolic activities mediate the formation of carcinogens during manufacturing. In recent years, studies have revealed a series of additional health impacts that include lesions and inflammation of the oral mucosa and the gastrointestinal tract, as well as alterations of the endogenous microbiota. These findings are due to recent developments in molecular technologies that allowed researchers to better examine the microbial component of these products. This new information illustrates the scale of the STP microbiota and its diversity in the finished product that is sold for consumption. Additionally, the application of metagenomics and metatranscriptomics has provided the tools to look at phylogenies across bacterial, viral, and eukaryotic groups, their functional capacities, and viability. Here we present key examples of tobacco microbiology research that utilizes newer approaches and strategies to define the microbial component of smokeless tobacco products. We also highlight challenges in these approaches, the knowledge gaps being filled, and those gaps that warrant further study. A better understanding of the microbiology of STP brings vast public health benefits. It will provide important information for the product consumer, impact manufacturing practices, and provide support for the development of attainable and more meaningful regulatory goals. KEY POINTS: Newer technologies allowed quicker and more comprehensive identification of microbes in tobacco samples, encapsulating microorganisms difficult or impossible to culture. Current research in smokeless tobacco microbiology is filling knowledge gaps previously unfilled due to the lack of suitable approaches. The microbial ecology of smokeless tobacco presents a clearer picture of diversity and variability not considered before.
