Use of Emerging and Conventional Oral Tobacco Among Adolescent and Young Adult E-Cigarette Users

Background: National surveillance assessing use of novel oral tobacco products (OTPs; nicotine pouches, lozenges, and gums not approved for tobacco cessation) among adolescents and young adults is limited. Objectives: To assess OTP behaviors in a sample of adolescent and young adult e-cigarette users, including use prevalence, dual/poly use with other products, and associated demographics. Methods: A national (United States) cross-sectional survey was conducted from March to April 2021 among 2253 participants (ages 14-20; 65% female) who ever used e-cigarettes >= 3 times. Demographics, lifetime use, and past 30-day use of 10 tobacco and cannabis products, including novel and conventional (chew, moist snuff, or snus) OTPs was assessed. Analysis was descriptive, examining use prevalence (lifetime and past 30-day) of each product, including by demographics and other product use. Results: Nearly 44% reported ever using any OTP, with nicotine pouches being the most commonly ever used (29%) and used in the past month (11%). Novel OTP use was more common among older participants (18-20 years), male participants, and past 30-day users of e-cigarettes, combustible tobacco, and conventional oral tobacco. However, female participants and combustible tobacco non-users were over twice and 4-times as likely, respectively, to use novel OTPs than conventional OTPs. Nearly 73% of past 30-day conventional OTP users were past 30-day novel OTP users. Conclusion: Novel OTP use was prevalent among adolescent and young adult e-cigarette users. Compared to conventional OTPs, novel OTPs likely have greater appeal to females and combustible tobacco non-users. Action to restrict access and reduce interest in OTPs is needed to prevent use among this population.
