Adolescent e-cigarette use before and after restrictions on flavored cartridges

In early 2020 the FDA finalized its enforcement policy on unauthorized flavored cartridge-based e-cigarettes, such as fruit and mint.  Consistent with this policy, the JUUL vaping brand removed all cartridge flavors other than menthol and tobacco from the market.  In this presentation I present national, U.S. data on adolescent e-cigarette use and attitudes before and after these restrictions on flavored cartridges.  Outcomes include e-cigarette prevalence, perceived availability of flavored e-cigarettes, as well as changes in use of JUUL and other vaping brands.  The presentation concludes with an assessment of the current state of the evidence on flavors and adolescent use of e-cigarettes and avenues for future investigation.
