Oral nicotine pouches are gaining popularity, yet national-level research on youth and young adult use is still needed. We examined characteristics of those who use oral nicotine pouches and trends in use over time in a sample of U.S. youth and young adults. Data were obtained from a weekly, national, online, continuous tracking survey of approximately 315 unique participants (aged 15-24) per week. Bivariate analyses were conducted on those surveyed December 2021 to May 2022 (n = 7,832) summarizing demographic and tobacco product use characteristics of those currently using oral nicotine pouches, those who had ever used oral nicotine pouches, but not currently, and those who never used pouches. From December 2021 to May 2022, 16% of participants ever used nicotine pouches and 12% currently used the product. Participants who currently used oral nicotine pouches were more likely to report being aged 21+, male, and lower income. Seventy-three percent of those who currently used pouches and 33% of those who ever, but not currently, used pouches reported current cigarette smoking. Results suggest that many young people who smoke cigarettes are concurrently using oral nicotine pouches. We also examined current and ever use in respondents surveyed between September 2020 and May 2022 to assess trends over the two-year period (n = 25,944) and findings indicate stable oral nicotine product use rates over time among adolescents and young adults. Appropriate regulation is needed so nicotine naïve individuals do not initiate use and those currently using tobacco do not use oral nicotine pouches concurrently with other products.
