Objectives. To review the implementation of the WHO Framework Convention onTobacco Control in theAmericas, describe two national case studies and analyze the evidence on electronic cigarettes from a public health perspective. Materials and methods. Revision of the tobacco control legislation and the scientific evidence regarding electronic cigarettes. Results. Implementation of tobacco control policies is not homogeneous, with important advances in smoke-free environments, pictorial health warnings, and epidemiological surveillance, but challenges that remain for the implementation of a total ban of tobacco advertising, increases in tobacco taxes, and tobacco cessation programs. Tobacco industry interference is one of the main obstacles for advancing and novel products create uncertainty about their regulation. Conclusion. There is a need for political will for a comprehensive implementation of the Convention, with evidence-based decisions to confront challenges and to defend the achievements from tobacco industry interference. ; Objetivos. Revisar la aplicación del Convenio Marco de la OMS para el Control del Tabaco en las Américas, describir dos estudios de caso nacionales y analizar la evidencia sobre los cigarrillos electrónicos desde la perspectiva de salud pública. Material y métodos. Revisión de la legislación de control de tabaco y la evidencia científica sobre los cigarrillos electrónicos. Resultados. La aplicación de políticas no es homogénea, con avances importantes en ambientes libres de humo, advertencias sanitarias gráficas y vigilancia epidemiológica, pero desafíos pendientes en la prohibición total de la publicidad, incremento de impuestos y cesación tabáquica.La interferencia de la industria tabacalera es uno de los principales obstáculos para avanzar y los nuevos productos crean incertidumbre sobre su regulación. Conclusiones. Se necesita revitalizar la voluntad política para aplicar integralmente el Convenio, tomando decisiones basadas en evidencia ante los nuevos desafíos y defendiendo los ...

This cross-sectional study estimates the association of political party affiliation with physical distancing behaviors among young adults during the coronavirus disease 2019 pandemic.

BACKGROUND: Tobacco 21 (T21) laws, which raise the minimum legal age of sale of tobacco products to 21, have been proposed and implemented in states and cities across the US. However, limited data are available on the effect of T21 laws on youth tobacco purchasing behaviors and access to tobacco products. METHODS: Participants in a population-based prospective cohort in southern California completed questionnaires before (N=1609, Age=18–19) and after (N=1502, Age=19–20) T21 was implemented in California (June 2016). We examined the prevalence of past 30-day cigarette and e-cigarette use, and among past 30-day users, purchase location of tobacco products before (Pre-) vs. after (Post-) T21. We also examined whether, Post-T21, participants were refused purchase of tobacco products due to their age, and the perceived relative ease of purchasing cigarettes and e-cigarettes (vs. Pre-T21). RESULTS: Negligible changes in cigarette and e-cigarette use were observed Pre-T21 vs. Post-T21. At both time points, the majority of past 30-day users purchased cigarettes from gas stations and e-cigarettes from vape shops. Post-T21, the proportion of participants who reported purchasing cigarettes at gas stations decreased. Post-T21, most past 30-day cigarette or e-cigarette users were not refused purchase of cigarettes (65.4%) or e-cigarettes (82.0%) in the past 30 days, despite being under 21; half of participants felt it was harder to purchase cigarettes (54.3%) and e-cigarettes (43.6%) Post-T21. CONCLUSION: Post-T21, few participants were refused purchase of any tobacco product, despite the illegality of such sales. Better enforcement of T21 is needed to improve the efficacy of T21 legislation.

Following the homicide of George Floyd on May 25, 2020, young adults participated widely in national protests against racism and police brutality. This study examined temporal trends and correlates of self-reported distress about police brutality from May 18 to August 3, 2020 among a cohort of young adults (ages 19–22; N = 2,080) from Los Angeles, CA. Bivariate and adjusted linear regression models estimated the association between survey completion date and distress about police brutality. Distress about police brutality increased substantially in the 2-weeks after Floyd's death (43% increase over baseline), but gradually declined over the ensuing 8 weeks to a 19% increase over baseline. Results suggest that police violence is contributing to stress and worry among young adults.

ObjectivesElectronic cigarettes (e-cigarettes) are available in nontraditional flavors (eg, fruit and candy) that are banned in combustible cigarettes in the United States. Whether adolescent use of e-cigarettes in nontraditional flavors prospectively predicts continuation of vaping and progression to more frequent vaping is unknown.MethodsHigh school students in Los Angeles, California, completed 5 semiannual surveys (2014-2017 [10th grade to 12th grade]). Among past-6-month e-cigarette users at survey waves 1 to 4 (N = 478), e-cigarette flavor (or flavors) used was coded into 2 mutually exclusive categories at each wave (use of ≥1 nontraditional flavors [fruit, candy, sweet or dessert, buttery, blends or combinations, and other] versus exclusive use of tobacco, menthol or mint, or flavorless). Flavor used during waves 1 to 4 was modeled as a time-varying, time-lagged regressor of vaping status and frequency outcomes 6 months later at waves 2 to 5.ResultsAcross waves 1 to 4, there were 739 (93.8%) observations of nontraditional-flavor use and 49 (6.2%) observations of exclusive use of tobacco, mint or menthol, or flavorless e-cigarettes. Use of e-cigarettes in nontraditional flavors (versus only tobacco, mint or menthol, or flavorless) was positively associated with vaping continuation (64.3% vs 42.9%; adjusted odds ratio = 3.76 [95% confidence interval 1.20 to 10.31]) and past-30-day number of puffs per nicotine vaping episode (mean: 3.1 [SD 5.5] vs 1.5 [SD 3.8]; adjusted rate ratio = 2.41 [95% confidence interval 1.08 to 5.92]) 6 months later. Flavor used was not associated with the subsequent number of past-30-day vaping days or episodes per day.ConclusionsAdolescents who vaped e-cigarettes in nontraditional flavors, compared with those who exclusively vaped tobacco-flavored, mint- or menthol-flavored, or flavorless e-cigarettes, were more likely to continue vaping and take more puffs per vaping occasion 6 months later.
