Patterns of blunt and cigar use in the United States, 2015-2019.

Background: The use of cigars for blunts (i.e., cannabis rolled in cigar paper) is well-documented; proportions of cigar and blunt use and associated characteristics are less studied. Methods: Pooled data from the 2015-2019 National Survey on Drug Use and Health (NSDUH) were analyzed in 2023. Respondents aged 12+ who reported past 30-day cigar use were categorized into three mutually exclusive use categories: (1) exclusively cigars, (2) exclusively blunts, and (3) both cigars and blunts. We examined associations between cigar-blunt use category and sociodemographic characteristics. Results: Among people 12 and older who reported past 30-day cigar use, 48.6% (95% CI=47.6-49.6) reported exclusive cigar use; 44.3% (95% CI=43.3-45.3) reported exclusive blunt use; and 7.2% (95% CI=6.8-7.6) reported cigars and blunts. The prevalence differed by age, with exclusively blunts most prevalent among youth (72.5% [95% CI=70.7-74.3]) and young adults (62.4% [95% CI=61.4-63.5]), and exclusively cigars most prevalent among adults 26+ (61.2% [95% CI=59.8-62.5]). Exclusive blunt users smoked more days in the past month (17.5; 95% CI=16.8-18.2), compared to 13.8 days (95% CI=13.2-14.4) for cigar and blunt users, and 7.7 days (95% CI=7.5-8.0) for exclusive cigar users. There were significant differences in characteristics, with exclusive blunt use more prevalent among female (41.6%; 95% CI=40.3-42.9) and Hispanic (18.2%; 95% CI=17.3-19.2) participants. Conclusions: Exclusive blunt use was the most prevalent pattern of past-30-day cigar use among youth and young adults. Those who use cigars as blunts smoke more cigars per month, suggesting this may be an important group for additional education and policy efforts.

Urinary Cotinine and Cotinine + Trans-3'-Hydroxycotinine (TNE-2) Cut-points for Distinguishing Tobacco Use from Nonuse in the United States: PATH Study (2013-2014).

BACKGROUND: Determine the overall, sex-, and racially/ethnically-appropriate population-level cotinine and total nicotine equivalents (TNE-2, the molar sum of the two major nicotine metabolites) cut-points to distinguish tobacco users from nonusers across multiple definitions of use (e.g., exclusive vs. polytobacco, and daily vs. non-daily). METHODS: Using Wave 1 (2013-2014) of the U.S. Population Assessment of Tobacco and Health (PATH) Study, we conducted weighted Receiver Operating Characteristic (ROC) analysis to determine the optimal urinary cotinine and TNE-2 cut-points, stratified by sex and race/ethnicity. RESULTS: For past 30-day exclusive cigarette users, the cotinine cut-point that distinguished them from nonusers was 40.5 ng/mL, with considerable variation by sex (male: 22.2 ng/mL; female: 43.1 ng/mL) and between racial/ethnic groups (non-Hispanic other: 5.2 ng/mL; non-Hispanic black: 297.0 ng/mL). A similar, but attenuated, pattern emerged when assessing polytobacco cigarette users (overall cut-point = 39.1 ng/mL, range = 5.5 ng/mL-80.4 ng/mL) and any tobacco users (overall cut-point = 39.1 ng/mL, range = 4.8 ng/mL-40.0 ng/mL). Using TNE-2, which is less impacted by racial differences in nicotine metabolism, produced a comparable pattern of results although reduced the range magnitude. CONCLUSIONS: Because of similar frequency of cigarette use among polytobacco users, overall cut-points for exclusive cigarette use were not substantially different from cut-points that included polytobacco cigarette use or any tobacco use. Results revealed important differences in sex and race/ethnicity appropriate cut-points when evaluating tobacco use status and established novel urinary TNE-2 cut-points. IMPACT: These cut-points may be used for biochemical verification of self-reported tobacco use in epidemiologic studies and clinical trials.

US young adults' perceived effectiveness of draft pictorial e-cigarette warning labels.

SIGNIFICANCE: Research shows that pictorial warning labels for cigarettes are more effective than text-only warnings, and preliminary work suggests that pictorial warnings could also be considered for electronic cigarettes (e-cigarettes). Pictorial warnings may be important for maximising their effectiveness among young people and enhancing the salience of the single nicotine addiction warning required for e-cigarettes to date in the USA. This study collected pilot data about the perceived effectiveness of draft e-cigarette pictorial warnings. METHODS: Participants were 876 young adults (ages 18-29) recruited through Amazon Mechanical Turk who completed an online e-cigarette survey in 2018. Participants viewed and ranked five versions of the same e-cigarette nicotine addiction warning message-four pictorial and one text-only-on their perceived noticeability, likelihood of capturing young people's attention, memorability, relevance to the addiction warning text and overall effectiveness in warning people about e-cigarette risks. For each outcome, presentation of the five warning versions was randomised. Pictorials included symbolic images of risk and addiction, and of priority audiences for the warning (ie, young people). RESULTS: For all outcomes, pictorial warnings were ranked higher than the text-only warning, and the warning using a yellow triangle caution icon was ranked highest for all outcomes. The text-only warning was ranked as the least likely to be effective for all four outcomes in which it was assessed. Trends were similar for current e-cigarette users and non-users. CONCLUSIONS: Future research should assess perceptions and the appropriateness of pictorial imagery for e-cigarette warnings and test their efficacy against text-only warnings experimentally.

The Impact of Smokeless Tobacco Risk Information on Smokers' Risk Perceptions and Use Intentions: A News Media Experiment.

Little research exists on the impact of risk information comparing smokeless tobacco (SLT) use, particularly snus, to cigarette smoking. This study explored this topic using a communication channel where smokers may be exposed to such information-the news media. We randomly assigned 1008 current smokers to read one of three constructed news stories or to a control group (no article). The "favorable" story framed snus as a "safer" smoking alternative while the "cautious" story described snus risks. The "mixed" version described potential risks and harm-reduction benefits. Participants completed a post-article survey with snus risk and harm perception and use intention measures. Article condition was significantly associated with perceived harm of daily snus use relative to smoking (1 = a lot less harmful - 5 = a lot more harmful; p < .0001), and mean ratings of snus harm in the favorable (2.46) and mixed conditions (2.66) were significantly lower than those of the cautious (2.96) and control conditions (2.98). Mean interest in trying snus in the next 6 months was low, but significantly higher for those in the favorable (1.55) and mixed conditions (1.32) versus those in the cautious (1.17) and control conditions (1.16)(1 = not at all - 5 = extremely interested, p < .0001). There were no significant differences by group in terms of the story's perceived interestingness, importance, or relevance. Exposure to reduced-risk news messages about SLT and snus relative to cigarettes may impact smokers' SLT harm perceptions and use intentions. Tobacco control professionals and FDA officials should consider the potential impact of the news media when communicating about tobacco risks.

Surveillance of Tobacco Use Among South Asians in the US: Are We Underestimating Prevalence?

This study employed a randomized split sample survey to assess the accuracy of standard tobacco surveillance measures among South Asians living in the US. 219 South Asian adults completed a web-based survey of "standard" tobacco use questions, as they appear in national surveillance surveys, and half were randomly assigned to also receive questions about South Asian tobacco products. Prevalence of tobacco use was compared by experimental condition, assessed by only the standard questions for the control group (N = 116) and by both standard and South Asian questions for the experimental group (N = 103). Among the experimental group, sensitivity and negative predictive value (NPV) of the standard use definitions were calculated, considering the inclusive definitions as the "gold standard." Prevalence of any tobacco product use was higher among the experimental group, as was prevalence of smokeless tobacco (SLT) use, relative to the control group (34.7 vs. 17.2 % and 21.2 vs. 4.3 %, respectively). 70.6 and 33.3 % of true tobacco users (any product) and SLT users were correctly classified by the respective standard product questions. A majority of gutka, paan with tobacco, and supari with tobacco users (69, 86, and 75 %, respectively) did not otherwise endorse the standard SLT questions. Current tobacco surveillance measures may underestimate the use of tobacco in the South Asian population residing in the US. These results indicate that careful consideration must be given to how tobacco-related questions are presented to minority populations.

Cigarettes, Smokeless Tobacco, and Poly-Tobacco Among Workers in Three Dusty Industries.

BACKGROUND: Tobacco use remains high among blue-collar workers, the health consequences of which may be compounded by occupational dust exposure. Detailed data on tobacco use among workers in dusty industries are lacking. METHODS: The 2006 to 2012 National Survey on Drug Use and Health was used to compare current tobacco use prevalence [including cigarettes, smokeless tobacco (SLT), and both (dual use)] among male workers in three dusty industries to all other employed men using bivariate and multivariate analysis. RESULTS: Smoking rates were high among extraction (39.9%) and construction (38.5%) workers. Increased odds of SLT (odds ratio = 3.3) and dual use (odds ratio = 2.6) were observed among dusty-industry workers compared with other employed men. The prevalence of any tobacco use was unexpectedly high among extraction workers (60.4%). CONCLUSIONS: Disparities in tobacco use behaviors by industry may point to opportunities for targeted workplace tobacco cessation programs.

Young adults' behavioral intentions surrounding a potential menthol cigarette ban.

INTRODUCTION: Menthol cigarette smoking is more prevalent among young adults, who are a known target of tobacco industry marketing. This study explores young adults' menthol use and behavioral intentions in the event of a ban on menthol cigarettes. METHODS: Data from 2,871 respondents of the 2011 National Young Adult Health Survey were examined to estimate young adults' current smoking, current menthol smoking, and behavioral intentions in the event of a menthol cigarette ban. RESULTS: Of all respondents, 23.8% were current smokers, and 40.3% of the current smokers were menthol smokers. Menthol use was significantly higher among 18- to 24-year-olds versus 25- to 34-year-olds (51% vs. 34.3%, p = .02) and was significantly associated with race/ethnicity (p < .0001), with prevalence highest among Black smokers (82.0%). Among menthol smokers, 65.7% indicated they would quit tobacco use altogether if menthol cigarettes were no longer sold, while 18.4% said they would switch to nonmenthol cigarettes, and 16.0% said they would switch to some other tobacco product (OTP). Behavioral intention was significantly associated with race/ethnicity (p = .02), where intention to quit tobacco was most prevalent among Black menthol smokers (79.3%), and concurrent use of OTPs (p = .03), where intention to switch to an OTP was more prevalent among menthol smokers who indicated concurrent OTP use (35.3% vs. 5.5%). CONCLUSIONS: A majority of young adult menthol smokers stated they would quit smoking if menthol cigarettes were no longer sold, which builds on research finding public support for such a policy and on work modeling the public health impact such a ban could have.

Examining market trends in the United States smokeless tobacco use: 2005-2011.

BACKGROUND: While cigarette consumption in the USA continues to decline, promotion for and consumption of smokeless tobacco (SLT) is growing. However, little research has explored what product features are driving SLT growth, despite awareness that product-level factors may be important in SLT use. This study analyses national sales data to better understand the impact of product features on SLT sales. METHODS: Data on sales of SLT in US convenience stores from 2005 to 2011 were obtained from Nielsen Research Company. Each listed product was coded for attributes such as type, brand, flavouring and form to calculate their respective total sales, market share and contribution to overall SLT growth. RESULTS: Sales of moist snuff products (including snus) increased by 65.6% between 2005 and 2011. Sales of pouched and flavoured forms of moist snuff increased by 333.8% and 72.1%, respectively, and contributed to 28% and 59.4% of the total growth in the moist snuff category, respectively. Value/discount brands accounted for 42% of moist snuff sales in 2011 among the top 10 selling brands, largely driven by Grizzly. After 2 years on the national market, Camel Snus was also one of the top 10 selling moist snuff brands. CONCLUSIONS: Sales of moist snuff, both overall and for particular styles, are increasing. Growing pouch use may be attributed to new SLT users, which may include cigarette smokers using them as starter SLT products. Increased sales of flavoured and discounted snuff raise concerns about use and appeal to youth. Continued surveillance of SLT sales trends is warranted.
