Objectives
Most tobacco policy studies neither examine the impact of smoking bans and taxes on individual behavior over time nor consider their interactive effects, and often overlook city-level contexts. We examine the mutual effects of these policies on smoking among a longitudinal cohort of young adults.
Methods
Combining a repository of U.S. tobacco policies with the nationally-representative geocoded National Longitudinal Survey of Youth 1997 from ages 19–31 and Census data, we use multilevel logistic regression to examine the impact of tobacco policies on any current and daily pack smoking.
Results
For current smoking, we find significant effects for comprehensive smoking bans, but not excise taxes. We also find an interaction effect, with bans being most effective in locales with no/low taxes. For daily pack smoking, we find significant effects for taxes, but limited support for bans.
Conclusions
Social smoking among young adults is primarily inhibited by smoking bans, but excise taxes only deter such smoking in the absence of a ban. Heavy smokers are primarily deterred by taxes. While both policies impact young adult smoking behaviors, their dual presence does not intensify each policy’s efficacy.
