ABSTRACT
BACKGROUND: The tobacco industry uses product descriptors to communicate reduced harm and increase appeal. This cross-sectional study assessed store-level racial, ethnic, and socioeconomic inequities in the distribution of retail tobacco product descriptors in a convenience sample of retailers in Washington, DC. METHODS: Young adults (n = 146) who did not currently use tobacco reported real-time store visits over 14 days. Trained data collectors took high-resolution photographs of all tobacco (including e-cigarette) marketing in each store (n = 96) participants visited. We coded text descriptors on tobacco product advertisements and displays into descriptor categories (eg, fruit, sweet, concept). We fit multilevel models to examine relationships between store neighborhood census tract-level racial, ethnic, and socioeconomic characteristics and tobacco product descriptors in stores. As a supplementary analysis, we used geospatial methods to model predicted patterns of descriptors at the census tract level. RESULTS: Stores located in census tracts with the highest versus lowest percentage of Black residents had a greater count of fruit, sweet or dessert, alcohol, and concept descriptors (pâ <â .05), similar to findings from the geospatial approach. Adjusted models also indicated some inequities in stores in census tracts with higher percentages of Hispanic or Latino residents for fruit, alcohol, and concept descriptors; however, tract-level models showed opposite results for concept flavors. CONCLUSIONS: In this convenience sample, fruit, alcohol, sweet/dessert, and concept FTP descriptors were prevalent in stores in neighborhoods with more Black residents demonstrated through two analytic approaches. Surveillance using representative samples of tobacco retailers could improve the ability to track the extent of this inequity. IMPLICATIONS: We document inequities in the amount of fruit, sweet or dessert, alcohol, and concept flavor descriptors in stores across neighborhoods in Washington, DC. Federal, state, and local regulatory action is needed to reduce inequities in flavored tobacco product availability and marketing, including for concept flavors.

INTRODUCTION: In recent years, hundreds of jurisdictions around the world have enacted policies that prohibit sales of flavored e-cigarettes. In most cases, these jurisdictions permit the sale of tobacco flavored e-cigarettes. We sought to understand how tobacco flavor in e-cigarette advertisements were presented. AIMS AND METHODS: Our sample included 2966 U.S. English-language e-cigarette ads compiled by a market research firm, Numerator, that ran from January 2018 to December 2020. We describe the prevalence of different tobacco flavor names in our sample and classified each name into one of the following thematic categories: Traditional Tobacco, Pipe/Cigar Tobacco, Sensory Expectancies, Color, Physical Attribute, Place, and non-characterizing Concept flavor. RESULTS: In our sample, 28% (nâ =â 832/2966) of ads promoted at least one tobacco flavored e-cigarette product (e-cigarette device or liquid). Across the 832 ads, we counted 1019 tobacco flavored products and identified 51 unique tobacco flavor names. The most common tobacco flavor names were Traditional Tobacco names like "Tobacco" (nâ =â 393), "Classic tobacco" (nâ =â 107) and 'Original' (nâ =â 59). Some names were associated with Color (eg, 'Golden tobacco'; nâ =â 153), Sensory Expectancy (eg, 'Rich tobacco'; nâ =â 148), Place where tobacco cultivation takes place (eg, 'Carolina tobacco'; nâ =â 83), Physical Attributes of tobacco (eg, 'Cut tobacco'; nâ =â 17) and non-characterizing Concept flavor (eg, 'Freedom juice'; nâ =â 14). Few tobacco flavors suggested a type of Pipe/Cigar Tobacco (eg, "Cavendish"; nâ =â 4). CONCLUSIONS: We identified 51 different tobacco flavor names, highlighting the practice describing the flavor beyond "tobacco." Future research can investigate whether these flavor names and descriptors influence consumers' perceptions, including perceived risks, of e-cigarette products. IMPLICATIONS: Flavors are used to market e-cigarettes. Globally, many jurisdictions restrict flavored e-cigarette sales, but few restrict tobacco flavor. This study identified 51 unique ways tobacco flavored e-cigarettes have been named in a sample of U.S. English-language ads, suggesting diversified ways to market "tobacco." We identified several sub-categories of tobacco flavor names that rely on Color, Sensory Expectancies, and non-characterizing Concept flavor attributes. As e-cigarette flavor restrictions that exempt tobacco flavor are still prevalent, this study highlights the need for continued monitoring of naming conventions of tobacco flavored products and examination of how nuanced flavor names influence perceptions and expectations.

Responsável por milhões de óbitos anuais e um grande custo para a saúde pública, o câncer é a segunda maior causa de mortes no mundo. Dentre seus diversos tipos, o câncer de pulmão, além da alta incidência, é um dos mais letais. A exposição a substâncias tóxicas provenientes da combustão de matéria orgânica, assim como o consumo de cigarro, são os principais responsáveis pela alta incidência de câncer de pulmão. Dentre estas substâncias, está o benzo[α]pireno (B[α]P), um carcinógeno completo, ou seja, capaz de iniciar e promover o processo de carcinogênese. Resultados anteriores obtidos pelo grupo demonstraram que células BEAS-2B expostas a 1 µM de B[α]P apresentaram alterações das concentrações de metabólitos intracelulares, indução de estresse redox e hipermetilação do DNA. A exposição a 1 µM de nicotinamida ribosídeo (NR), um dos precursores de NAD+, foi capaz de proteger as células BEAS-2B contra a transformação induzida por B[α]P, além de impedir totalmente que células não expostas a B[α]P formassem colônias em soft-agar. A utilização da proteômica neste trabalho permitiu verificar a abundância das proteínas nos quatro diferentes grupos de exposição: Controle, B[α]P, B[α]P + NR e NR. Após 120 h de exposição as células foram coletadas, as proteínas extraídas e preparadas para análise. Foram descobertas 3024 proteínas posteriormente analisadas com o objetivo de elucidar vias possivelmente envolvidas na proteção contra o processo de transfomação maligna. Os grupos NR e Controle demonstram ser mais parecidos em relação ao seu conteúdo, enquanto os grupos B[α]P e B[α]P + NR foram mais semelhantes entre si. A análise de proteínas exclusivas revelou menos processos relacionados ao reparo de DNA no grupo tratado apenas com B[α]P quando comparado com B[α]P + NR. A análise estatística do total de proteínas utilizando o teste ANOVA (p < 0,05, N = 5) revelou 564 proteínas diferencialmente expressas entre os grupos. A clusterização nos permitiu observar a diferença na abundância de proteínas entre os quatro tratamentos. As proteínas estão envolvidas em funções como a regulação do metabolismo, resposta a estresse, transdução de sinal, regulação de expressão gênica e morte celular. Um dos clusters (cluster 1), contendo 59 proteínas, revelou poucos processos na análise de enriquecimento, mas as proteínas contidas nele apresentam funções como controle da divisão celular, apoptose e proteção ao estresse redox. Nele podemos observar que, no geral, o tratamento com B[α]P aumentou a abundância de algumas proteínas, o que foi revertido no grupo B[α]P + NR. O tratamento apenas com NR diminuiu a abundância das proteínas contidas nesse cluster. Outro cluster (cluster 4) apresentou 51 proteínas de abundância diminuída durante a exposição ao B[α]P, o que se reverteu no grupo B[α]P + NR. As proteínas desse cluster estão envolvidas em etapas importantes da via glicolítica, de crescimento, adesão, migração e invasão celular. Apesar de ser descrito que a exposição a NR pode aumentar a eficiência do reparo de DNA, os resultados apresentados nesse trabalho indicam que o efeito protetor pode estar relacionado com a modulação do ciclo celular ou alterações na adesão celular
Responsible for millions of annual deaths and a great health expense, cancer is the second leading cause of death in the world. Among its many types, lung cancer, besides its high incidence, is also one of the most lethal. Exposure to toxic substances resulting from the combustion of organic matter, as well as cigarette consumption, are the mainly responsible for the high incidence of lung cancer. One of these substances is benzo[α]pyrene (B[α]P), a complete carcinogen, able to initiate and promote the carcinogenesis process. Results obtained previously demonstrated that BEAS-2B cells exposed to 1 µM BaP presented alterations in the levels of intracellular metabolites, induction of oxidative stress, and hypermethylation of DNA. The exposure to 1 µM nicotinamide riboside (NR), one of the precursors of NAD+, was able to protect BEAS-2B cells against the transformation induced by B[α]P, moreover, it also totally prevented the colonies formation on soft agar in cells not exposed to B[α]P. The use of proteomics allowed us to verify the abundance of proteins in the four different exposure groups: Control, B[α]P, B[α]P + NR e NR. After 120h of exposure, the cells were collected followed by the extraction of the proteins. A total of 3024 proteins were identified and analyzed aiming to elucidate possible pathways involved in the protective effect against the malignant transformation induced by B[α]P. The NR and Control groups showed to be more similar, while B[α]P and B[α]P + NR were more similar. The analysis of exclusive proteins revealed fewer processes related to DNA repair in B[α]P when compared with B[α]P + NR. The statistical analysis of the total proteins using the ANOVA test (p <0.5, N = 5) revealed 564 proteins differentially expressed between the groups. The heatmap showed the difference in protein abundance between the four treatments. Proteins are involved in functionssuch asthe regulation of metabolism, stress response, signal transduction, regulation of gene expression, and cell death. One of the clusters (cluster 1), containing 59 proteins, revealed a few processes in the enrichment analysis, but the proteins contained in it have functions such as control of cell division, apoptosis, and protection from redox stress. It is possible to observe, in general, treatment with B[α]P increased the abundance of some proteins, which was partially reversed in group B[α]P + NR. On the other hand, the NR treatment decreased the abundance of proteins contained in this cluster. Another cluster (cluster 4) showed 51 proteins of decreased abundance during exposure to B [α] P, which was partially reversed in group B[α]P + NR. The proteins in this cluster are involved in important stages of the glycolytic pathway, also in growth, adhesion, migration, and cell invasion. Although it has been described that exposure to NR can increase the efficiency of DNA repair, the results presented in this work indicate that the protective effect may be related to the modulation of the cell cycle or cell adehsion modifications

BACKGROUND: The trend of the diffusion of heated tobacco products (HTPs) is a great concern because HTPs have become available worldwide. This study examined the sociodemographic characteristics of HTPs users in Japan, where HTPs were first launched. METHODS: This cross-sectional study used data from an online survey conducted in 2017. A total of 4,926 participants, aged 20-69 years, were included. The dependent variable was the type of tobacco products used. The independent variables were age and equivalent income. Two analyses estimated the odds ratios (ORs) for 1) being smokers compared to "non-smokers," and 2) being "HTP smokers" compared to "only combustible cigarette smokers." Analyses were stratified by sex. Educational attainment and occupation were also used in the sensitivity analyses. RESULTS: The percentages of "non-smokers," "only combustible cigarette smokers," and "HTP smokers" were 82.8%, 14.2%, and 3.0%, respectively. When compared to the oldest participants (aged 60-69), the youngest participants (aged 20-29) tended to be "HTP smokers" (OR 7.90; 95% confidence interval [CI], 3.09-20.22 for men and OR 9.28; 95% CI, 2.14-40.28 for women). Compared to participants with the lowest incomes (<2 million), those with the highest incomes (≥4 million) tended to use HTPs (OR 2.93; 95% CI, 1.56-5.49 in men and OR 1.82; 95% CI, 0.73-4.54 in women). These trends were consistent when analyses included only smokers. There were consistent results in other SES measurements, including educational attainment and occupation. CONCLUSIONS: Younger or more affluent people tended to use HTPs, although smoking rates among these populations were generally lower. New tobacco control efforts are required.

BACKGROUND: Relationships between cigarette filter ventilation levels, biomarkers of exposure (BOE) and potential harm (BOPH), and harm perceptions were examined. METHODS: Filter ventilation levels in cigarette brands were merged with Wave 1 (2013-2014) Population Assessment of Tobacco Use and Health study. Data were restricted to smokers who reported a usual brand and not regular users of other tobacco products. BOEs included nicotine, tobacco-specific nitrosamines, volatile organic compounds (VOC), and polycyclic aromatic hydrocarbons. BOPHs measured inflammation and oxidative stress. Perceived harm was assessed as self-reported risk of one's usual brand compared with other brands. RESULTS: Filter ventilation ranged from 0.2% to 61.1% (n = 1,503). Adjusted relationships between filter ventilation and BOE or BOPH were nonsignificant except for VOC N-acetyl-S-(phenyl)-L-cysteine (PHMA) and high-sensitivity C-reactive protein (hsCRP). In pairwise comparisons, PHMA was higher in quartile (Q) 4 (4.23 vs. 3.36 pmol/mg; P = 0.0103) and Q3 (4.48 vs. 3.36 pmol/mg; P = 0.0038) versus Q1 of filter ventilation and hsCRP comparisons were nonsignificant. Adjusted odds of perceiving one's own brand as less harmful was 26.87 (95% confidence interval: 4.31-167.66), 12.55 (3.01-52.32), and 19.18 (3.87-95.02) times higher in the Q2, Q3, and Q4 of filter ventilation compared with Q1 (P = 0.0037). CONCLUSIONS: Filter ventilation was not associated with BOE or BOPH, yet smokers of higher ventilated cigarettes perceived their brand as less harmful than other brands compared with smokers of lower ventilated cigarettes. IMPACT: Research to understand the impact of this misperception is needed, and remedial strategies, potentially including a ban on filter ventilation, are recommended.

OBJECTIVE: We assessed the prevalence and factors associated with living with tobacco/nicotine product users among nicotine-naïve adolescents. METHODS: Data were from the 2018 Florida Youth Tobacco Survey that included 34,183 adolescents who were never-tobacco product users and provided information about living with tobacco/nicotine users. RESULTS: More than a quarter of adolescents lived with a tobacco/nicotine user. Girls were more likely than boys and middle-schoolers were more likely than high-schoolers to live with someone who uses cigarettes, cigars, and poly-tobacco. Compared to non-Hispanic Whites, Hispanics were less likely to live with someone who uses cigarettes, electronic nicotine delivery systems, cigars, and poly-tobacco. Adolescents who reported currently having asthma were more likely to report living with someone who smokes cigarettes, hookah, and poly tobacco. CONCLUSIONS: To reduce and ideally eliminate exposure to smoke/aerosol emitted from tobacco products in nicotine-naïve adolescents, individual and family-centered interventions, coupled with state-wide tobacco prevention strategies are warranted.

OBJECTIVE: To determine the penetration of heated tobacco products (HTPs) into the youth market in Taiwan, with a particular focus on the correlation between IQOS use and the usage of other tobacco products. METHODS: Data from the 2018 Global Youth Tobacco Survey were used to assess previous experience with and current use (within 30 days prior to survey completion) of IQOS products by Taiwanese students aged 12-18 years. Independent variables included the usage patterns of conventional cigarettes and e-cigarettes. The control variables included background information (gender, grade, monthly income/allowance, household educational level, smoking status at home and among close friends), access to free cigarettes, as well as exposure to cigarette advertisements and anti-tobacco courses. Logistic regression was used to identify tobacco usage patterns correlated with IQOS use. RESULTS: In 2018, 2.33% of Taiwan's adolescents were currently using IQOS and 4.17% had tried IQOS. The use of conventional cigarettes and e-cigarettes (individually and together) were associated with an elevated risk of the ever use and current use of IQOS. CONCLUSION: Despite the fact that HTP products are not sold legally in Taiwan, the use of IQOS products by young people is far from negligible. We recommend amending the "Tobacco Hazards Prevention Act" to include regulations pertaining to the sale and marketing of HTPs.

BACKGROUND: Healthcare professionals might play a significant role in tobacco control. The aims of this study were to investigate tobacco cigarette and electronic cigarette (e-cigarette) consumption among university students enrolled in courses of the healthcare area, and to understand whether training in healthcare could induce to smoking cessation. STUDY DESIGN: Cross-sectional survey using a self-administered, structured questionnaire. METHODS: Tobacco smoking habits of 560 students of four different medical area courses at the University of Milan, enrolled both in the first and in the last course year during the 2017-2018 academic year, were collected. RESULTS: The prevalence of smokers was 34.8%, almost the same for males and females, and higher in Italian students compared to foreigners. Smoking prevalence was higher among employed (46.9%) than unemployed (35.1%) students, without differences between healthcare and non-healthcare workers. The influence of family, and particularly friends, is confirmed to be relevant. About 25% of respondents tried e-cigarettes, mainly smokers (44.6%) and former smokers (38.6%) with the goal of quitting smoking. More than 44% were dual users of both tobacco cigarettes and e-cigarettes. Comparing smoking habits between first-year and final-year students, only students of healthcare assistance course showed a significant drop in smoking during the university studies. CONCLUSIONS: The implementation of specific educational curricula on smoking dangers and on smoking cessation techniques might have the double effect of supporting students in quitting smoking and of properly preparing them for their future task of helping people to quit smoking.

In 2018, the United States Food and Drug Administration (FDA) issued an advanced notice of proposed rulemaking to reduce nicotine in tobacco products to produce a minimally addictive or nonaddictive effect, but there was a research gap in the subjective responses of reduced-nicotine-content cigarettes. We compared the responses of the modified cigarette evaluation questionnaire (mCEQ) and cigarette-liking scale (CLS) between the gradually reduced nicotine content (RNC) group and the usual nicotine content (UNC) group. Linear mixed-effects models for repeated measures were used to analyze and compare the change over time for the mCEQ and CLS across the two treatment groups (RNC and UNC). We found that the change over time for the mCEQ and CLS was significant between the RNC and the UNC treatment groups at the beginning of visit 6 with 1.4 mg nicotine/cigarette. At visits 8 and 9, the RNC group reported significantly lower satisfaction scores compared to UNC. Subscale analysis showed that smoking satisfaction decreased in RNC while other measures, such as cigarette enjoyment, did not change. Understanding the impact of nicotine reduction on cigarette subjective responses through evaluation and liking scales would provide valuable information to the FDA on nicotine reduction policies for cigarettes.

BACKGROUND: From among the global public health concerns, smoking remains one of the most crucial challenges. Especially for adolescents, the increase in the use of electronic cigarettes is controversial, as its use may lead to established smoking. In Japan, where a unique tobacco regulation system exists, the heat-not-burn tobacco market has been growing. However, the prevalence and association of combustible cigarettes and new tobacco-related products have not yet been closely investigated among Japanese adolescents. This study aimed to clarify the prevalence of smoking among adolescents, including new types of tobacco-related products, and to compare the characteristics of their users. METHODS: The 2017 Lifestyle Survey of Adolescents is a nationally-representative survey collected in Japan. From the national school directory, 98 junior high schools and 86 high schools were randomly sampled throughout Japan. The students completed an anonymous questionnaire at school. We calculated the prevalence of use for each type of tobacco product. Then, the use of a combination of products and the characteristics of different types of products were examined. RESULTS: In total, 64,152 students from 48 junior high schools and 55 high schools were included the analysis (school response rate = 56%, Mage = 15.7 years, 53.9% boys). The age-adjusted rate of ever (current) use of electronic cigarettes was 2.1% (0.7%) in junior high school and 3.5% (1.0%) in high school; that of combustible cigarettes was 2.6% (0.6%) in junior high school and 5.1% (1.5%) in high school. The rate of heat-not-burn tobacco use was lower relative to other products: 1.1% (0.5%) in junior high school and 2.2% (0.9%) in high school. An examination of the combined use of the three products identified a high number of dual users. Comparisons between different types of users indicated different backgrounds for combustible cigarette users and new product users. CONCLUSIONS: The prevalence of new tobacco-alternative products is growing in popularity among Japanese adolescents. Dual use is common, and many adolescents use new products only. Moreover, e-cigarettes might attract a broader range of groups to smoking. Continuous monitoring and research are needed to investigate their influence as a possible gateway to tobacco smoking.

BACKGROUND AND OBJECTIVES: This is the first study to assess the appeal and interest among adults in a new consumer tobacco product, ZYN. We also describe ZYN users, patterns of use, and reasons for use. METHODS: Two data sets, consisting of a ZYN-naive consumer panel (n = 5179) and ZYN users (n = 1266), were provided by Swedish Match North America. Descriptive, cross-sectional analyses and logistic regression assessed the perceptions of and likelihood of buying ZYN in the consumer panel and the characteristics of ZYN users. RESULTS: The majority of current smokeless tobacco (ST) users in the consumer panel found that ZYN was moderately-extremely appealing, while never and former tobacco users indicated much less interest; the former were more likely to buy ZYN than other groups. The highest percentage of ZYN users were former tobacco users (43%); very few were never users (4%). The most popular reason for using ZYN was "Less harmful to my health than other tobacco products," followed by "ease of use." DISCUSSION AND CONCLUSIONS: Nonusers of tobacco had very little interest in ZYN. ST users are not only more interested and likely to buy ZYN than other tobacco users, they were the largest group of regular users. SCIENTIFIC SIGNIFICANCE: The first assessment of a new nicotine product, ZYN, suggests that current and former tobacco users may perceive ZYN as a reduced-risk product. ZYN potentially could be used as a smoking/tobacco-cessation aid based on reasons of current users. (Am J Addict 2020;00:00-00).

INTRODUCTION: Use of menthol cigarettes remains highly prevalent among African American smokers and has increased among White and Hispanic/Latino smokers. Research is needed to examine if behavioral factors, such as marijuana use, are differentially associated with menthol cigarette use among racially/ethnically diverse samples of marijuana users. METHODS: Using data from the 2017 National Survey on Drug Use and Health, this study examined the association between past month marijuana (blunt versus non-blunt) and cigarette (non-menthol cigarette versus menthol cigarette versus no cigarette) use, as well as racial/ethnic differences in this relationship. RESULTS: Among all marijuana users (Nâ¯=â¯5,137), 34.1% smoked blunts, 28.7% smoked non-menthol cigarettes and 18.0% smoked menthol cigarettes, with the highest rates of blunt (63.8%) and menthol cigarette (38.9%) use found among African American adults. Multinomial logistic regression analyses revealed a significant association between blunt use and non-menthol cigarette use (versus non-use) and menthol cigarette use (versus non-menthol cigarette and no cigarette use) among the full sample. When stratified by race/ethnicity, this finding was consistent for non-Hispanic White (nâ¯=â¯3,492) and partially consistent for Hispanic/Latino (nâ¯=â¯839) adults. However, among African American adults (nâ¯=â¯806), blunt use was not significantly associated with non-menthol cigarette use or menthol cigarette use. DISCUSSION: Blunt use is associated with increased odds of non-menthol and menthol cigarette use, but only among Hispanic/Latino and White adults. Examining racial/ethnic differences in the association between marijuana and tobacco use is important to understanding disparities and informing prevention and treatment interventions and drug policies.

INTRODUCTION: Most tobacco use is initiated during adolescence and susceptibility is an important predictor of initiation. Research is needed to understand susceptibility across tobacco products among youth to inform prevention efforts. AIMS AND METHODS: We surveyed 2945 students from four Southeastern Connecticut high schools in 2017. We assessed susceptibility to future use of seven different tobacco products (ie, cigarettes, e-cigarettes, hookah, cigars, cigarillos, blunts, and smokeless tobacco) among youth who had never used a tobacco product. Susceptibility was coded as any response other than "definitely not" to three items assessing (1) curiosity, (2) willingness to experiment with the product in the future, and (3) willingness to try if offered by a friend. Latent class analysis was used to identify patterns of susceptibility across multiple tobacco products and sociodemographic predictors of these classes. RESULTS: Among n = 1246 youth who had never tried a tobacco product, 51.2% (n = 638) were susceptible to at least one product and 29.1% (n = 363) were susceptible to two or more products (average among susceptible youth: M = 2.4 products, SD = 1.7, range 1-7). Latent class analysis identified three classes: youth who were: (1) susceptible to all products (5.6%), (2) susceptible to e-cigarettes, hookah, and blunts (23.6%), and (3) mostly non-susceptible to all products (70.8%). In a multivariable model, demographic variables and peer tobacco use predicted class membership. CONCLUSIONS: We observed high rates of susceptibility to non-traditional tobacco products among youth, and many youth were susceptible to more than one product. Targeting susceptibility across multiple tobacco products may be important for reducing youth tobacco use. IMPLICATIONS: Patterns of polytobacco use susceptibility were identified among youth who had never previously used tobacco products. Many youth were susceptible to more than one product and we observed three distinct classes of susceptibility among youth: those who were mostly non-susceptible, those who were susceptible to alternative or non-traditional tobacco products (e-cigarettes, hookah, and blunts), and those who were susceptible to all tobacco products. These findings suggest the importance of addressing susceptibility across multiple tobacco products.

INTRODUCTION: Studies largely focus on nicotine-containing e-cigarettes (NiCE) though non-nicotine-containing e-cigarettes (NoCE) exist; NoCE prevalence and patterns of use are largely unknown. This study examines self-reported prevalence and patterns of NiCE/NoCE use. METHODS: We analyzed adult (18+ years) data from the Population Assessment of Tobacco and Health (PATH) study from Wave 1 (2013-2014, n = 32,320), Wave 2 (2014-2015, n = 28,632), and Wave 3 (2015-2016, n = 28,148). We test associations between Wave 1 self-reported current NoCE/NiCE use status and demographic characteristics and assess the proportion of self-reported current NoCE/NiCE users at Wave 1 or Wave 2 who continue to use NoCE or NiCE, switch to NiCE or NoCE, discontinue e-cigarette use, switch to use other nicotine products (ONP), or add ONP use 1 year later (i.e., at Wave 2 or 3). RESULTS: Maintaining the same self-reported NiCE/NoCE and ONP use status 1 year later was the most common use pattern between waves. However, 15.65% of exclusive NoCE users in Wave 2 transitioned to NoCE plus nicotine product use in Wave 3. Also, some exclusive NoCE users transitioned to exclusive NiCE use (17.77% Waves 1-2; 11.55% Waves 2-3). DISCUSSION: Some exclusive NoCE users transitioned to NiCE or added nicotine product use, suggesting there may be other factors (e.g., familiarity with using an aerosolizing device) in addition to the presence of nicotine in influencing initiation or sustained use of nicotine products. IMPLICATIONS: Studies largely focus on nicotine-containing e-cigarettes (NiCE) though non-nicotine-containing e-cigarettes (NoCE) exist; this study adds to the literature by describing demographic characteristics and tobacco use of adult self-reported NoCE users. In addition, the study examines transitions in self-reported NoCE/NiCE use, revealing that some exclusive NoCE users transition to other nicotine product use 1 year later.

INTRODUCTION: We investigated heated tobacco products (HTPs) use and associated factors in Chinese adults in Hong Kong where HTPs are not formally marketed yet, and cigarette smoking prevalence was the lowest in the developed world. METHODS: A population-based landline telephone survey in 2017 interviewed 5131 (45.2% male; 26.7% aged ≥60) adults to collect information on awareness, intention to use, ever use of HTPs, cigarette smoking status and sociodemographic characteristics. Descriptive statistics were weighted by the age, sex and smoking status of the Hong Kong adult population. Sociodemographics were mutually adjusted in logistic regression to yield adjusted ORs (AORs) for awareness of HTPs, controlling for smoking status. RESULTS: Overall, 11.3% (95% CI 10.0% to 12.7%) were aware of HTPs and 1.0 % (0.8%-1.2%) had ever used it. Awareness was associated with aged 40-49 years (AOR 1.37, 95% CI 1.01 to 1.87) or 30-39 years (2.03, 1.41-2.91) (vs ≥60 years), born in Hong Kong (1.37, 1.11-1.68) and higher monthly household income (p for trend 0.001). Ever HTP users had higher educational attainment and monthly household income, and more were aged 30-39 and economically active (all p<0.003). In never HTP users, intention to use HTPs (7.3%, 4.9%-10.8%) were more prevalent in respondents with similar characteristics (all p<0.008). More current (vs never) smokers were aware of HTPs, intent to use HTPs and had ever used HTPs (all p<0.001). CONCLUSION: Higher socioeconomic status was associated with HTP use and intention to use. Public health education on HTPs is needed especially for this high-risk group.

INTRODUCTION: This study aimed to develop a method for discriminating cigarette brands based on the profiles of volatile components extracted from the tobacco fraction of the finished cigarettes to authenticate branded cigarettes of unknown origin. METHODS: An analytical method comprising direct thermal desorption coupled with gas chromatography-quadrupole time-of-flight mass spectrometry was developed for acquiring volatile profiles of cigarettes. About 290 samples of commercially available cigarettes were analyzed. Within this batch, 123 samples represented four popular cigarette brands. They were selected for in-depth characterization. Multivariate analysis was used to investigate the interrelations among volatile compounds of cigarettes and to identify characteristic markers for the cigarette discrimination. Supervised pattern recognition techniques were used for designing classification models. RESULTS: Principal component analysis covering all detected volatiles allowed the differentiation of cigarettes based on the brand. A number of 56 volatile components were identified as markers with high discrimination power. These compounds were used for establishing classification models. A method of soft independent modeling of class analogy developed for the four studied cigarette brands proved to be efficient in the classification of unknown cigarettes, with accuracy between 95.9% and 100%. CONCLUSIONS: The data evaluation by soft independent modeling of class analogy was highly accurate in classification of unknown cigarettes with a low rate of false positives and false negatives. The developed models can be used for discrimination of genuine from non-genuine products with high level of probability. IMPLICATIONS: Profiling of volatiles, which is commonly used for authentication of different food commodities, was applied for the characterization of cigarette tobacco for the purpose of authentication a cigarette brand. Volatile components with a high discrimination power were identified by means of multivariate statistical methods and used for establishing of a classification model. The classification model was able to discriminate genuine from non-genuine cigarettes with a high level of prediction accuracy. This model could be a powerful tool for tobacco control to judge the authenticity of cigarettes.

BACKGROUND: Plain packaging and minimum pack size legislation for tobacco products was introduced in the UK in May 2016, with a 1-year sell-off period until May 2017, during which both fully branded and plain packs of various sizes were legally available. This study investigates trends in prices of roll-your-own tobacco (RYO) before, during and after implementation of this legislation, and compares trends with those observed in the cigarette market. METHODS: We used Nielsen Scantrack data for the period from March 2013 to June 2018 to describe trends in UK inflation-adjusted prices and volumes of both RYO and cigarettes, and linear regression to estimate changes in prices associated with the introduction of plain packaging and the minimum pack sizes of 30 g RYO and 20 cigarettes. RESULTS: In contrast to a downward trend in cigarette sales volumes, RYO volumes rose throughout the study period. By the time plain packs accounted for 75% or more of sales, the average price of products sold in equivalent pack sizes had increased, relative to average prices in the year before implementation and with adjustment for tax changes, from 34.9 to 38.8 pence per gram for RYO (mean difference 4.26, 95% CI 3.99 to 4.53 pence, 12% increase), and from 38.6 to 41.13 pence for cigarettes (mean difference 2.53, 95% CI 2.24 to 2.83 pence, 7% increase) per cigarette. CONCLUSIONS: New legislation resulted in higher prices for RYO and manufactured cigarettes. However, sales volumes of RYO continued to increase throughout the study period, perhaps because RYO remains a less expensive means of smoking tobacco.

INTRODUCTION: A mandated reduction in the nicotine content of cigarettes may decrease smoking, but also increase demand for other nicotine products. The present study tested the impact of smoking cigarettes with very low nicotine content and concurrent use of a transdermal nicotine patch. STUDY DESIGN: A balanced 2â¯×â¯2 factorial randomized clinical trial investigating the impact of cigarette nicotine content (double-blind, very low nicotine content versus normal nicotine content) and use of a transdermal nicotine patch (open label, patch versus no patch). SETTING/PARTICIPANTS: Adult daily smokers (n=240) in the Pittsburgh, PA area. INTERVENTION: Participants were provided with research cigarettes and transdermal nicotine patches (if assigned to patch condition) for 7 weeks. Cigarettes were Spectrum brand (National Institute on Drug Abuse) and either 15.8 mg nicotine/g tobacco (normal nicotine content) or 0.4 mg nicotine/g tobacco (very low nicotine content). In the 7th week, participants were monetarily incentivized to abstain from smoking. MAIN OUTCOME MEASURES: Participants reported daily cigarette use throughout the trial and the primary outcome was average number of cigarettes smoked per day (studyâ¯+â¯nonstudy) during Week 6. Participants were recruited from 2015 to 2017 and data were analyzed between 2017 and 2018. RESULTS: Assignment to very low nicotine content cigarettes and assignment to wear a nicotine patch both reduced the number of cigarettes smoked per day during Week 6 (p=0.001 and 0.04, respectively). However, assignment to the patch along with very low nicotine content cigarettes did not significantly reduce cigarette smoking compared with assignment to very low nicotine content cigarettes alone. CONCLUSIONS: A mandated reduction in the nicotine content of cigarettes is likely to reduce the number of cigarettes smoked per day, but the added benefit of concurrent transdermal nicotine is unclear. Future studies should investigate whether alternative sources of noncombusted tobacco, such as e-cigarettes, enhance the effects of very low nicotine content cigarettes on smoking.
