Reactions to hypothetical flavor bans among current users of flavored e-cigarettes

Banning flavors in e-cigarettes and other tobacco products may decrease their use. To examine how current users of flavored e-cigarettes might react to a ban on flavored e-cigarettes when: (i) menthol flavor is banned together with other flavors, or (ii) this ban on e-cigarettes is combined with a ban on menthol cigarettes and flavored cigars. A national cross-sectional survey of 2,347 current users of flavored e-cigarettes was conducted in May 2022. For each hypothetical ban scenario, respondents reported if they would quit all tobacco product use, continue to use e-cigarettes with no flavor or flavors that were not banned, or switch to alternative tobacco products. Multinomial logistic regressions were used to estimate the associations between responses and ban scenarios, adjusting for tobacco use and demographic variables.If e-cigarettes with any flavors except menthol and tobacco were banned, the majority of current e-cigarette users would keep using e-cigarettes with no flavor or tobacco and menthol flavor. When menthol flavor was added to a ban, a greater proportion of respondents would quit all tobacco use; however, more would also switch to cigarettes or cigars. When menthol cigarettes and flavored cigars were added to a ban, those who used menthol flavor only would be less likely to switch to cigarettes and cigars.Among current e-cigarette users, the harm reduction (i.e., from quitting all use) from a ban on flavored e-cigarettes, particularly if menthol is also banned, may be outweighed by the harm increases (i.e., switching to cigarettes or cigars, or other products that are more harmful than using e-cigarettes). A concurrent ban on menthol cigarettes and flavored cigars would secure more certain net reductions to public health harms from e-cigarette use and smoking.For current flavored e-cigarette users, the harm reduction (i.e., from quitting all use) from a ban on flavored e-cigarettes, particularly if menthol is also banned, may be outweighed by the harm increases (i.e., switching to cigarettes or cigars, or other products that are more harmful than using e-cigarettes).Banning flavors in e-cigarettes and other tobacco products has the potential to decrease their use. We examined how current users of flavored e-cigarettes might react to several hypothetical ban scenarios. We found that if e-cigarettes with any added flavors except tobacco or menthol were banned, the majority of current e-cigarette users would keep using non-flavored e-cigarettes or those with flavors that were not banned. When menthol flavor was added to a ban, a greater proportion of respondents would quit all tobacco use, however, more would also switch to cigarettes or cigars. When menthol cigarettes and flavored cigars were added to a ban, those who used menthol-flavor e-cigarettes only would be less likely to switch to cigarettes and cigars. Our study indicated that among current e-cigarette users, the harm-reduction resulting from a ban on flavored e-cigarettes, particularly when menthol was banned (i.e., from users quitting all use), may be outweighed by the harm increases (i.e., switching to cigarettes or cigars, or other products that are more harmful than using e-cigarettes). Concurrently banning menthol cigarettes and flavored cigars would secure more certain net harm reductions.
