The purpose of this study is to present images featuring various alternative nicotine and nicotine-like vaping products to assess adolescents' and young adults' harm and appeal perceptions of, and susceptibility to use these products, as well as to assess whether these perceptions and susceptibility are moderated by participants' age, sex at birth, race and ethnicity, nicotine and non-nicotine current use, and exposure to nicotine and tobacco product content on social media.
This randomized online survey-based experiment was aimed to be conducted among a national sample of U.S. adolescents and young adults recruited by an online panel Cint. Participants viewed three images of flavored disposable vaping products in one of four conditions: synthetic/tobacco-free nicotine, zero-nicotine, ambiguous nicotine ("clean"/ "pure"), or tobacco nicotine (control). After each image harm and appeal perceptions, and susceptibility/intention to use these products, as well as interactions of the experimental conditions with participants' age, sex at birth, race and ethnicity, nicotine and non-nicotine current use, and exposure to nicotine and tobacco product content on social media. Generalized estimating equation models assessed the associations between the experimental conditions and the outcomes.
