More information about the impact of menthol-flavored e-cigarettes in enabling menthol cigarette smokers to switch to e-cigarettes would be useful. The goal of this study is to compare the efficacy of menthol-flavored versus tobacco-flavored e-cigarettes in facilitating switching from combustible cigarettes to e-cigarettes among adult menthol smokers. Researchers will randomize 800 menthol smokers (≥ age 21) into a 12-week trial comparing menthol-flavored and tobacco-flavored e-cigarettes, with follow-up at week 26. Study aims are: (1) to compare the effectiveness of menthol versus tobacco e-cigarettes at facilitating switching (measured by cigarette and e-cigarette use patterns) at week 12; (2) to compare tobacco harm reduction of menthol versus tobacco e-cigarettes (measured by self-reported health-related quality of life, expired carbon monoxide, respiratory measures, and blood pressure) at week 12; (3) to compare the acceptability of menthol versus tobacco e-cigarettes (measured by product use; effects on withdrawal, craving, and dependence; and subjective and sensory effects) at week 12; and (4) to examine the long-term use of menthol versus tobacco e-cigarettes at week 26. Findings may inform future regulatory activities related to menthol flavoring in e-cigarettes.
