Dual users of e-cigarettes and combusted cigarettes comprise 40% of multiple tobacco product users. The goal of this research is to evaluate the potential effects of limiting e-cigarette/e-liquid flavors to tobacco-only on preference for combusted cigarettes. In this study, 280 adult dual users (aged 18 and older) will undergo preference sessions during which they will make choices between an e-cigarette and a combusted cigarette. Study aims are to evaluate users’ self-reported anticipated choices if e-liquid flavors would be limited to tobacco only on: (1) choices for usual brand cigarettes; (2) choices for menthol and non-menthol cigarettes (among menthol-preferring participants); and (3) choices for cigarettes with normal nicotine content versus very low nicotine content. Findings may inform regulatory activities related to product standards.
