Concerns Over Vuse e-Cigarette Digital Marketing and Implications for Public Health Regulation: Content Analysis.

Background: Electronic cigarettes (e-cigarettes) are the most used form of tobacco products among adolescents and young adults, and Vuse is one of the most popular brands of e-cigarettes among US adolescents. In October 2021, Vuse Solo became the first e-cigarette brand to receive marketing granted orders (MGOs) from the US Food and Drug Administration (FDA), authorizing its marketing and their tobacco-flavored pods. Vuse Ciro and Vuse Vibe, and their tobacco-only ("original") e-liquids, were authorized for marketing in May 2022 and Vuse Alto tobacco-flavored devices were authorized in July 2024.

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.

Vaping nicotine and cannabis on the same occasion is linked to increased vaping consumption among young adults: A smartphone-based daily diary study.

Significance: Vaping both nicotine and cannabis in the past 30 days (co-vaping) is common among young adults. It is unclear which co-vaping patterns may increase substance use and dependence. We examined day-level associations between vaping patterns with vaping quantity.

Short-Form Video Informed Consent Compared With Written Consent for Adolescents and Young Adults: Randomized Experiment.

Background: Adolescents and young adults have the highest prevalence of e-cigarette use ("vaping"), but they are difficult to enroll in health research studies. Previous studies have found that video consent can improve comprehension and make informed consent procedures more accessible, but the videos in previous studies are much longer than videos on contemporary social media platforms that are popular among young people.

Objective: This study aimed to examine the effectiveness of a short-form (90-second) video consent compared with a standard written consent for a vaping cessation study for adolescents and young adults.

Changing Trends of Excess Self-protective Behavior, and Association with Belief in Prevention Myths During the COVID-19 Epidemic in China: A Panel Study.

Participants were recruited for an online panel survey. There are 150 participants for the baseline and 102 for the final survey.

Flavored Tobacco Product Use Among California Adolescents Before and Immediately After a Statewide Flavor Ban.

Introduction: In December 2022, a California law banned the retail sale of most flavored tobacco products (including e-cigarettes). This investigation evaluates adolescents' use of flavored tobacco before and after enactment.

Methods: The Teens Nicotine and Tobacco Project included online surveys of California adolescents (age 12-17) in 2022 (N=5127) and 2023 (N=5015) that assessed past 30-day use of various tobacco products, flavored product use, and perceived access to flavored e-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.

Discussion of Heated Tobacco Products on Twitter Following IQOS's Modified-Risk Tobacco Product Authorization and US Import Ban: Content Analysis.

Background: Understanding public opinions about emerging tobacco products is important to inform future interventions and regulatory decisions. Heated tobacco products (HTPs) are an emerging tobacco product category promoted by the tobacco industry as a "better alternative" to combustible cigarettes. Philip Morris International's IQOS is leading the global HTP market and recently has been subject to important policy events, including the US Food and Drug Administration's (FDA) modified-risk tobacco product (MRTP) authorization (July 2020) and the US import ban (November 2021).

Changes in Sources of Information about the Risks and Benefits of Cannabis in a National Cohort of US Adults from 2017 - 2021.

Objective: As more states legalize cannabis in the US, marketing from the cannabis industry and news coverage of cannabis have increased.

Desires and Needs for Quitting Both e-Cigarettes and Cigarettes Among Young Adults: Formative Qualitative Study Informing the Development of a Smartphone Intervention for Dual Tobacco Cessation.

Background: Dual use of both e-cigarettes and cigarettes is popular among young adults and may lead to greater nicotine dependence and additive adverse health effects than single-product use. However, existing cessation programs target quitting either e-cigarettes or cigarettes, highlighting a need for interventions to help young adults quit both products (ie, dual tobacco cessation).

Objective: This formative study is part of a larger project to develop a smartphone intervention for dual tobacco cessation among young adults.

Social Media Exposure and Other Correlates of Increased e-Cigarette Use Among Adolescents During Remote Schooling: Cross-Sectional Study.

Background: Little is known about the role of exposure to e-cigarette-related digital content, behavioral and mental health factors, and social environment on the change in adolescent e-cigarette use during COVID-19 shelter-in-place orders and remote schooling.

Objective: The aim of the study was to examine changes in adolescent e-cigarette use during shelter-in-place and remote schooling in association with exposure to e-cigarette-related digital content and other correlates: stronger e-cigarette dependence, feeling lonely, inability to socialize, e-cigarette use to cope with shelter-in-place, and the number of family members aware of participants' e-cigarette use.

Methods: A cross-sectional survey conducted between August 2020 and March 2021 included 85 California adolescents (mean age 16.

Cigarette smoking status and COVID-19 hospitalization in the context of cannabis use: An electronic health record cohort study in northern California.

Global landscape of nicotine and tobacco products additives policies.

Introduction: Product design is a key tobacco industry strategy to recruit consumers and hinder cessation. An important technology in tobacco product design is the use of additives including those that create characterising flavours, that is, flavours that are perceived by taste and or smell by the user. To curb youth use, many countries are implementing policies to limit the use of flavours and other additives in tobacco products.
