Menthol smokers (n=800), stratified by race, will be randomized 1:1 into a 12-week open label, non-inferiority trial comparing a 4th generation nicotine salt-based pod-system e-cigarette in menthol- versus tobacco-flavored e-liquid. Follow-up will continue through week 26. The primary outcome is rate of switching from combustible cigarettes to e-cigarettes at week 12.
This study will compare the efficacy of menthol-flavored versus tobacco-flavored 4th generation nicotine salt-based pod-system e-cigarettes in facilitating a switch from combustible cigarettes to e-cigarettes in adult menthol smokers.
