Why young adults use tobacco-free nicotine E-cigarettes: An analysis of qualitative data

Abstract

BackgroundTobacco-free nicotine (TFN) is often marketed as being better tasting and healthier than tobacco-derived nicotine (TDN). Studies have yet to systematically characterize subjective experiences using TFN e-cigarettes. This qualitative study explored young adults’ reasons for using TFN e-cigarettes and perceptions of differences between using TFN and TDN e-cigarettes. MethodWe conducted a national online Qualtrics survey of U.S. young adults aged 18–25 years in October 2021. Respondents who reported lifetime TFN e-cigarette use (n = 317, mean age: 20.8 (SD:2.2), 53.9 % female) provided write-in responses to open-ended questions assessing reasons for using TFN e-cigarettes and perceptions of differences between TFN and TDN e-cigarettes. Responses from participants were thematically analyzed by independent raters. ResultsReasons for using TFN e-cigarettes included product taste/flavor, health reasons (e.g. believing TFN was healthy), and product accessibility. Perceptions of differences between TFN and TDN e-cigarettes included differences in taste/ flavor and acute psychoactive and physical effects (e.g., nicotine buzz, throat hit), with TFN e-cigarettes being described as generally stronger and superior relative to TDN e-cigarettes. ConclusionThese qualitative data suggest that taste and perceived health benefits are primary reasons that young adults try TFN e-cigarettes. Compared to TDN, young adults perceive TFN as better tasting with different psychoactive and less aversive effects. Determining if these perceived reasons for use and differences occur in blinded human experimental studies is a necessary next step to understanding TFN e-cigarette use. Additionally, understanding why young adults use TFN e-cigarettes is important in the development of prevention communication about these products.
