Examining the relationship of flavored tobacco product policy restrictions and flavored tobacco product use, among adolescents and young adults in the U.S

Objective: This work examines the relationship between local flavor policy exposure and any tobacco product use and flavored tobacco product use among U.S. youth and young adults, as well as the equity potential of these policies by race/ethnicity. Methods: Participants were aged 15-36 (n = 10,893) surveyed from September-December 2019 using national, address- and probability -based sampling. Local flavor policies enacted before survey completion were linked to participant home address. Weighted cross-sectional multivariable logistic regression examined individual coverage by flavor policy vs. no flavor policy, with current any tobacco or flavored tobacco use, controlling for individual and county -level demographics, psychosocial variables, and other tobacco control policies. Interactions between race/ethnicity and any tobacco use and flavored tobacco use were assessed. Results: Those covered by a flavor policy vs. no policy had lower odds of any tobacco use (aOR = 0.74, 95% CI = 0.55-1.00) and current flavored tobacco use (aOR = 0.67, 95% CI = 0.48-0.93). Compared with Non -Hispanic (NH) -White individuals, NH -Black individuals (aOR = 1.08, CI = 1.04-1.12) had higher odds of any tobacco use, and non -Hispanic Asian individuals had lower odds of any tobacco use (aOR = 0.67, CI = 0.53-0.85). Hispanic individuals exposed to policy had lower odds of flavored tobacco use compared to NH -White peers. Conclusions: Exposure to flavor restriction policies is associated with lower odds of any tobacco and flavored use among youth and young adults. Flavor restrictions may be beneficial in reducing tobacco use in youth from diverse racial/ethnic backgrounds. However, passing policies covering NH -Black individuals is needed to mitigate disparities in tobacco use by flavor policy coverage over time.
