Historical and political context for Philip Morris International's continuing medical education courses on harm reduction.

In 2024, Philip Morris International's (PMI) website stated they support 'independent' continuing medical education courses on harm reduction for medical and other healthcare professionals. These courses mirrored industry marketing and political strategies by presenting smokeless tobacco products and e-cigarettes as alternatives to smoking, sometimes without mentioning tobacco cessation. The enactment of the US Family Smoking and Tobacco Control Act gave the US Food and Drug Agency jurisdiction over tobacco products and included the industry's 'continuum of risk' frame, and emboldened tobacco companies to make harm reduction claims about these products, which they had previously avoided for fear of triggering restrictive regulation of cigarettes.

Cannabis legalization and changes in cannabis and tobacco/nicotine use and co-use in a national cohort of U.S. adults during 2017-2021.

Background: Little is known about whether cannabis legalization impacts cannabis use uptake or has spillover effects on co-use of cannabis and tobacco/nicotine (using both in the past 30 days). We determined associations of cannabis legalization with self-reported (1) current (past 30-day) cannabis use; (2) current ("now") tobacco/nicotine use (smoking or electronic cigarette use); and (3) current co-use of cannabis and tobacco/nicotine and how prevalence is changing over time.

Methods: In this longitudinal study, a web-based survey was administered to a nationally representative, population-based panel of US adults in 2017, 2020, and 2021.

More than a "characterizing flavor": Menthol at subliminal levels in tobacco products.

Introduction: In addition to imparting flavor, menthol in menthol-flavored cigarettes enhances nicotine addiction and increases experimentation, initiation, and progression to regular smoking. Menthol can be added to cigarettes at perceptible levels (so-called flavored cigarettes or characterized flavored cigarettes) or non-perceptible levels (subliminal). Our objective was to understand the reasons that tobacco companies use subliminal menthol.

Awareness of tobacco industry tactics among tobacco control communities in Thailand and its association with attitudes towards tobacco industry and perceptions of e-cigarettes.

Background: Tobacco industry denormalisation is a key strategy recommended by the WHO Framework Convention on Tobacco Control as it is associated with reducing smoking behaviours and positively influencing public and policymakers' opinion towards tobacco control. However, studies of awareness of tobacco industry tactics among public health players and policymakers in low-income and middle-income countries are limited.

Methods: We conducted an online survey of individuals who had been involved in tobacco control in Thailand.

Association of Cannabis Use With Cardiovascular Outcomes Among US Adults.

Background: We examined the association between cannabis use and cardiovascular outcomes among the general population, among never-tobacco smokers, and among younger individuals.

Methods And Results: This is a population-based, cross-sectional study of 2016 to 2020 data from the Behavioral Risk Factor Surveillance Survey from 27 American states and 2 territories. We assessed the association of cannabis use (number of days of cannabis use in the past 30 days) with self-reported cardiovascular outcomes (coronary heart disease, myocardial infarction, stroke, and a composite measure of all 3) in multivariable regression models, adjusting for tobacco use and other characteristics in adults 18 to 74 years old.

Population-Based Disease Odds for E-Cigarettes and Dual Use versus Cigarettes.

BACKGROUND: E-cigarettes are promoted as less harmful than cigarettes. There has not been a direct comparison of health effects of e-cigarettes or dual use (concurrently using e-cigarettes and cigarettes) with those of cigarettes in the general population. METHODS: Studies in PubMed, EMBASE, Web of Science, and PsychINFO published through October 1, 2023, were pooled in a random-effects meta-analysis if five or more studies were identified with a disease outcome.

Smoking in Popular Streaming Shows and Youth Protection in Germany.

Aim was to investigate the amount of smoking in popular streaming series in Germany with a focus on the comparison between series recommended for adults versus youth. The sample was drawn from the 35 highest user-rated streaming series, that released 1794 new episodes between January 1, 2017 and December 31, 2020. One-third of the episodes (N = 598) were randomly selected and analyzed for smoking content.

Smoking and healthcare expenditure reductions associated with the California Tobacco Control Program, 1989 to 2019: A predictive validation.

Background: Previous research used data through 2008 to estimate a model for the effect of the California Tobacco Control Program (CTCP) that used cumulative real per capita tobacco control expenditure to predict smoking behavior (current adult smoking prevalence and mean cigarette consumption per current smoker). Predicted changes in smoking behavior due to the CTCP were used to predict its effect on health care expenditure. This research updates the model using the most recently available data and estimates CTCP program effect through 2019.

Vuse Solo e-cigarettes do not provide net benefits to public health: a scientific analysis of FDA's marketing authorisation.

In October 2021, the US Food and Drug Administration (FDA) authorised marketing of RJ Reynolds Vapor Company's (RJR) Vuse Solo e-cigarette through FDA's Premarket Tobacco Product Application (PMTA) pathway. FDA concluded that RJR demonstrated Vuse products met the statutory standard of providing a net benefit to public health. A review of FDA's scientific justification reveals deficiencies: (1) not adequately considering Vuse's popularity with youth and evidence that e-cigarettes expanded the nicotine market and stimulate cigarette smoking; (2) trading youth addiction for unproven adult benefit without quantifying these risks and benefits; (3) not considering design factors that appeal to youth; (4) not addressing evidence that e-cigarettes used as consumer products do not help smokers quit and promote relapse in former smokers; (5) not discussing evidence that dual use is more dangerous than smoking; (6) narrowly focusing on the fact that e-cigarettes deliver lower levels of some toxicants without addressing direct evidence on adverse health effects; (7) downplaying significant evidence of other substantial harms; (8) not acting on FDA's own study showing no all-cause mortality benefit of reducing (but not stopping) cigarette use; and (9) improperly considering e-cigarettes' high abuse liability and potential for high youth addiction and undermining tobacco cessation.

e-Cigarettes Used by Adolescents to Try to Quit Smoking Are Associated With Less Quitting: A Cross-Sectional Analysis of the National Youth Tobacco Survey.

Purpose: This paper determines the association between youth e-cigarette use "to try to quit using other tobacco products, such as cigarettes" and having stopped smoking cigarettes (defined as an ever cigarette smoker who did not smoke in the past 30 days).

Methods: This study uses data from the NYTS from 2015 through 2021, focusing on youth who started smoking cigarettes before they started using e-cigarettes. Associations between using e-cigarettes to quit and having stopped smoking were computed using logistic regression accounting for the complex survey design and adjusting for level of nicotine dependence, year, age, gender, and race/ethnicity.

Nicotine Addiction and Intensity of e-Cigarette Use by Adolescents in the US, 2014 to 2021.

Importance: As e-cigarettes have become more effective at delivering the addictive drug nicotine, they have become the dominant form of tobacco use by US adolescents.

Objective: To measure intensity of use of e-cigarettes, cigarettes, and other tobacco products among US adolescents and their dependence level over time.

Design, Setting, And Participants: This survey study analyzed the cross-sectional National Youth Tobacco Surveys from 2014 to 2021.

Impairment of Endothelial Function by Cigarette Smoke Is Not Caused by a Specific Smoke Constituent, but by Vagal Input From the Airway.

Background: Exposure to tobacco or marijuana smoke, or e-cigarette aerosols, causes vascular endothelial dysfunction in humans and rats. We aimed to determine what constituent, or class of constituents, of smoke is responsible for endothelial functional impairment.

Methods: We investigated several smoke constituents that we hypothesized to mediate this effect by exposing rats and measuring arterial flow-mediated dilation (FMD) pre- and post-exposure.

Longitudinal bidirectional association between youth electronic cigarette use and tobacco cigarette smoking initiation in Thailand.

Introduction: This study quantifies the longitudinal association between e-cigarette use and subsequent conventional cigarette initiation and vice versa among Thai youths.

Methods: Data from a longitudinal survey of 6045 Thai seventh grade students with baseline in 2019 and the 12-month follow-up in 2020 were analysed using complex survey multivariate logistic regressions to assess whether e-cigarette use was associated with subsequent cigarette smoking (ever, current and dual product users at follow-up) among baseline never smokers.

Results: Consistent with prior findings from other countries, among those who had never smoked cigarettes at baseline, ever e-cigarette users were more likely to try cigarette smoking (adjusted OR 4.

Content Analysis of the Corporate Social Responsibility Practices of 9 Major Cannabis Companies in Canada and the US.

Importance: The cannabis industry has sought to normalize itself and expand its markets in the 21st century. One strategy used by companies to generate positive public relations is corporate social responsibility (CSR). It is critical to understand these efforts to influence the public and politicians given the risks of increased cannabis use.

Securing Smokefree Laws Covering Casinos and Bars in Louisiana via Messaging, Continuous Campaigning and Health Coalitions.

In this paper, we examine efforts by health organizations seeking comprehensive smokefree ordinances over Louisiana casinos and bars between 2010 and 2020 to determine best practices for increasing coverage. Bars and casinos remain less protected from secondhand smoke compared to other workplaces in the United States. Casino behavior is compared to the Policy Dystopia Model (PDM), a tobacco industry strategy framework.

Active Smokers Are at Higher Risk of COVID-19 Death: A Systematic Review and Meta-analysis.

Introduction: Current evidence indicates that smoking worsens COVID-19 outcomes. However, when studies restricted their analyses to current smokers, the risks for COVID-19 severity and death are inconsistent.

Aims And Methods: This meta-analysis explored the association between current smoking and the risk for mortality based on the studies that reported all three categories of smoking (current, former, and never smokers) to overcome the limitation of the previous meta-analyses which former smokers might have been classified as nonsmokers.

Tobacco industry thwarts ad ban legislation in India in the 1990s: Lessons for meeting FCTC obligations under Articles 13 and 5.3.

Bans on tobacco advertising are important for reducing tobacco-caused disease. Previously secret internal tobacco industry documents and organizational and newspaper websites related to tobacco control efforts in India during 1990s were analyzed. The Ministry of Health and Family Welfare, World Health Organization, Indian Council of Medical Research, and civil society played important roles in pushing for tobacco control legislation beginning in the 1980s.

Sociodemographic Characteristics Associated With and Prevalence and Frequency of Cannabis Use Among Adults in the US.

Importance: Cannabis use has increased, but there are few studies on frequent and daily cannabis use among US adults. Individuals who engage in higher frequency use may suffer more health consequences.

Objective: To examine frequency of cannabis use and associated factors among US adults.
