Analysis of e-cigarette warning letters issued by the Food and Drug Administration in 2020 and 2021.

Purpose: This study analyses the Food and Drug Administration (FDA) warning letters sent to e-cigarette companies from 1 January 2020 to 9 September 2021. Study results can inform regulation of e-cigarettes.

Methodology: Warning letters retrieved from FDA's website were coded for company type (retailer, manufacturer or distributor), location (domestic or international), infractions listed (PMTA (premarket tobacco product application), selling to minors, advertising to youth or packaging violation/mislabelling), product type (e-liquid, device or both), flavour (fruit, candy, tobacco, menthol/mint, concept flavour) and consequence (civil money penalties, product seizure and injunction, product detention and refusal of entry to the USA, no-tobacco-sales order, criminal prosecution).

The Influence of Provaping "Gatewatchers" on the Dissemination of COVID-19 Misinformation on Twitter: Analysis of Twitter Discourse Regarding Nicotine and the COVID-19 Pandemic.

Background: There is a lot of misinformation about a potential protective role of nicotine against COVID-19 spread on Twitter despite significant evidence to the contrary. We need to examine the role of vape advocates in the dissemination of such information through the lens of the gatewatching framework, which posits that top users can amplify and exert a disproportionate influence over the dissemination of certain content through curating, sharing, or, in the case of Twitter, retweeting it, serving more as a vector for misinformation rather than the source.

Objective: This research examines the Twitter discourse at the intersection of COVID-19 and tobacco (1) to identify the extent to which the most outspoken contributors to this conversation self-identify as vaping advocates and (2) to understand how and to what extent these vape advocates serve as gatewatchers through disseminating content about a therapeutic role of tobacco, nicotine, or vaping against COVID-19.

Smoking cessation among US adults: use of e-cigarettes, including JUUL, and NRT use.

Background: Electronic cigarettes (e-cigarettes) are a common tobacco product in the US. Despite lacking Food and Drug Administration (FDA) approval for cessation, e-cigarettes, including JUUL, a popular device, have been viewed by some as a potential tool for tobacco users seeking to quit combustible tobacco use. It is unknown how current and former smokers report using these products for cigarette smoking cessation.

Electronic Cigarette and JUUL Use Among Adolescents and Young Adults.

Objective: To estimate the prevalence, patterns, and factors associated over time with e-cigarette use among adolescents and younger adults in the United States.

The availability of retail tobacco near federally qualified healthcare facilities and addiction treatment centers in New York State.

The effectiveness of tobacco control policies that create smoke-free healthcare facilities and encourage the delivery of tobacco dependence treatment may be undermined by the availability of retail tobacco in the surrounding environments. This study examined the availability of retail tobacco in relation to: federally qualified health centers and look-a-like (FQHC/LAL) healthcare facilities (n = 706) as well as substance abuse and addiction treatment centers (n = 953) across New York State (NYS) in 2018. A statewide tobacco retailer density surface using static-bandwidth kernel density estimation was constructed from geocoded licensed tobacco vendors (n = 21,314).

Digital Segmentation of Priority Populations in Public Health.

The rapid growth and diffusion of digital media technologies has changed the landscape of market segmentation in the last two decades, including its use in promoting prosocial and behavior change. New, population-specific and culturally appropriate prevention strategies can leverage the potential of digital media to influence health outcomes, especially for the greatest users of digital technology, including youth and young adults. Health behavior change campaigns are increasingly shifting resources to social media, creating opportunities for innovative interventions and new research methods.
