The role of social media influencer promotion in initiation and use of cigar, little cigar, cigarillo, and cannabis products among US youth and young adults: Using exogenous marketing exposure measure…
Copromotion across commercial determinants of health: Content analysis of smokeless tobacco social media messages referencing alcohol, 2016–2021
Our analysis of ATST content on X/Twitter revealed the evidence of strategic comarketing of smokeless and alcohol products, specifically coordinated activities leveraging cultural narratives to normalise substance use. Social media's unregulated space facilitates cross-substance promotion, linking smokeless tobacco with alcohol through strategic product placement and lifestyle associations. These findings highlight the need for new prevention and…
Deciphering Influence on Social Media: A Comparative Analysis of Influential Account Detection Metrics in the Context of Tobacco Promotion
Influencer marketing spending in the United States was expected to surpass $6 billion in 2023. This marketing tactic poses a public health threat, as research suggests it has been utilized to undercut decades of public health progress-such as gains made against tobacco use among adolescents. Public health and public opinion researchers need practical tools to capture influential accounts on social media. Utilizing X (formerly Twitter) little ciga…
Disclosure Standards for Social Media and Generative Artificial Intelligence Research: Toward Transparency and Replicability
Social media dominate today's information ecosystem and provide valuable information for social research. Market researchers, social scientists, policymakers, government entities, public health researchers, and practitioners recognize the potential for social data to inspire innovation, support products and services, characterize public opinion, and guide decisions. The appeal of mining these rich datasets is clear. However, there is potential ri…
The Effects of Tobacco Coverage in the Public Communication Environment on Young People’s Decisions to Smoke Combustible Cigarettes
In today’s complex media environment, does media coverage influence youth and young adults’ (YYA) tobacco use and intentions? We conceptualize the “public communication environment” and effect mediators, then ask whether over time variation in exogenously measured tobacco media coverage from mass and social media sources predicts daily YYA cigarette smoking intentions measured in a rolling nationally representative phone survey (N = 11,847 on 1,1…
Association between E-Cigarette Advertising Exposure and Use of E-Cigarettes among a Cohort of U.S. Youth and Young Adults
Youth and young adult (YYA) use of e-cigarettes increased rapidly between 2010 and 2019 in the United States, during which exposure to e-cigarette advertising was also increased. We aimed to examine whether exposure to e-cigarette advertising among YYAs may lead to subsequent e-cigarette use. A cohort of 3886 YYAs ages 13-24 was recruited from two survey panels in 2018 and followed up until 2019. Survey data were collected online and by telephone…
Online Tobacco Advertising and Current Chew, Dip, Snuff and Snus Use among Youth and Young Adults, 2018–2019
Greater exposure to tobacco advertising online is associated with greater odds of smokeless use among surveyed youth and young adults. This effect of social media marketing exposure on smokeless use outweighs the mitigating impact of existing tobacco control policies. The findings underscore the need for strong advertising regulation of evolving tobacco products, including smokeless products, on social media and surveillance of digital marketing …
Heating Up: How Early Twitter Marketing Gave Rise to Organic Word-of-Mouth About Heated Tobacco Products
Social media are an important marketing platform for emerging tobacco products. Heated tobacco products (HTPs) have been introduced in a limited number of local test markets in the United States as potentially reduced-exposure tobacco products. HTPs can be used to heat tobacco as well as marijuana. However, due to growing digital media promotion of these products, it is possible that public knowledge and purchasing opportunities extend beyond tes…
The Association between E-Cigarette Price and TV Advertising and the Sales of Smokeless Tobacco Products in the USA
This study aims to examine how e-cigarette prices and advertising, key determinants of e-cigarette demand, are associated with the demand for smokeless tobacco (SLT) products in the US. Market-level sales and price data by year (2010-2017), quarter, and type of retail store were compiled from Nielsen retail store scanner database. E-cigarette TV advertising ratings data were compiled from Kantar Media. Four-way (market, year, quarter, store type)…
The Story of Goldilocks and Three Twitter’s APIs: A Pilot Study on Twitter Data Sources and Disclosure
Public health and social science increasingly use Twitter for behavioral and marketing surveillance. However, few studies provide sufficient detail about Twitter data collection to allow either direct comparisons between studies or to support replication. The three primary application programming interfaces (API) of Twitter data sources are Streaming, Search, and Firehose. To date, no clear guidance exists about the advantages and limitations of …
E-cigarette advertising expenditures in the United States, 2014–2018
E-cigarette advertising expenditures have been volatile in the USA, with declines in traditional advertising venues during 2014-2017 that may reflect a shift towards social media. However, an increase occurred in 2018 that is likely reflective of advertising by newer manufacturers. Continued monitoring of e-cigarette advertising is important to inform tobacco control strategies
At the speed of Juul: Measuring the Twitter conversation related to ENDS and Juul across space and time (2017–2018)
Juul-related content grew exponentially on Twitter and spread across the entire country during the time when the brand was gaining market share. This social media buzz continued to increase even after FDA's multiple interventions to curb promotions targeting minors
Toward an Aggregate, Implicit, and Dynamic Model of Norm Formation: Capturing Large-Scale Media Representations of Dynamic Descriptive Norms Through Automated and Crowdsourced Content Analysis
Media content can shape people’s descriptive norm perceptions by presenting either population-level prevalence information or descriptions of individuals’ behaviors. Supervised machine learning and crowdsourcing can be combined to answer new, theoretical questions about the ways in which normative perceptions form and evolve through repeated, incidental exposure to normative mentions emanating from the media environment. Applying these methods, t…
Characterising Juul-related posts on Instagram
Findings reveal a proliferation of JUUL-related content on Instagram, which focused on product promotion and nicotine and addiction that included youth culture and lifestyle appeals. Regulatory actions should focus on restricting promotional efforts for e-cigarette products, particularly on social media platforms where young people are a primary audience
Vaping versus Juuling: How the extraordinary growth and marketing of Juul transformed the US retail e-cigarette market
Background While national surveys showed declines in e-cigarette use in the USA between 2015 and 2016, recent reports indicate that JUUL, a sleekly designed e-cigarette that looks like a USB drive, is increasingly being used by youth and young adults. However, the extent of JUUL’s growth and its marketing strategy have not been systematically examined. Methods A variety of data sources were used to examine JUUL retail sales in the USA and its mar…
Sweeter Than a Swisher’: Amount and themes of little cigar and cigarillo content on Twitter
Twitter is a major information-sharing and marketing platform for LCCs. Co-use of tobacco and marijuana is common and normalised on Twitter. The presence and broad reach of LCC messages on social media warrants urgent need for surveillance and serious attention from public health professionals and policymakers. Future tobacco use prevention initiatives should be adapted to ensure that they are inclusive of LCC use
Price-related promotions for tobacco products on Twitter
This study demonstrates that the vast majority of tweets offering price promotions focus on e-cigarettes. Future studies should examine the extent to which Twitter users, particularly youth, notice or engage with these price promotion tweets
Are You Scared Yet? Evaluating Fear Appeal Messages in Tweets About the Tips Campaign: Are You Scared Yet
In March 2012, the CDC launched "Tips from Former Smokers," a $54 million national campaign featuring individuals experiencing long-term health consequences of smoking. The campaign approach was based on strong evidence that anti-tobacco ads portraying fear, graphic images, and personal testimonials are associated with attitudinal and behavior change. Yet it was also controversial; critics cited the danger that viewers might reject such intensely…
The Effects of Smoking-Related Television Advertising on Smoking and Intentions to Quit Among Adults in the United States: 1999–2007
Objectives. We investigated whether state-sponsored antitobacco advertisements are associated with reduced adult smoking, and interactions between smoking-related advertising types. Methods. We measured mean exposure to smoking-related advertisements with television ratings for the top-75 US media markets from 1999 to 2007. We combined these data with individual-level Current Population Surveys Tobacco Use Supplement data and state tobacco contro…
