A thematic analysis of Puff Bar-related content on TikTok.

Background : Puff Bar has rapidly captured a large proportion of the disposable e-cigarette market. To stay abreast of the rapidly changing e-cigarette-product landscape, researchers have turned to social media platforms to monitor e-cigarette-related discussions and marketing trends. TikTok is the latest social media platform to capture the attention of adolescents and young adults; however, e-cigarette-related research using TikTok is limited. Objectives : This study examined Puff Bar-related posts on TikTok to identify themes and user engagement. Methods : Data were collected by scraping publicly available TikTok posts that contained the hashtag #puffplus, between January 31, 2020 and May 4, 2021 ( n  = 581). The research team used an inductive approach to identify 19 themes from the data. User engagement with posts including the number of likes, shares, plays, and comments was also collected. Results : The most prevalent themes included Music at 75.39% (438/581), followed by Flavors at 51.64% (300/581), Youth/Young Adults at 42.86% (249/581), Tobacco Use at 41.14% (239/581), Nicotine Concentration at 35.11% (204/581), Humor at 19.45% (113/581) and Product Review at 19.1% (111/581). Cessation 1.38% (8/581) and Health Warnings 2.58% (15/581) were two themes rarely observed but commonly engaged with by TikTok users. Conclusions : Health communication strategists should prepare to address TikTok's popularity to combat its contribution to the online e-cigarette environment. Future research should determine the impact of exposure to Puff Bar-related content on TikTok on adolescents' and young adults' attitudes and behaviors.
