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.


Description:

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.

Outcome

Type Measure Description Time frame Safety issue
Primary Number of participants who switch from cigarettes to electronic cigarettes at Week 12 Complete switching is defined as exclusive use of e-cigarettes, confirmed with CO< 6ppm and predominant switching; defined as use of the e-cigarette with >50% reduction in CPD. This will compare the effectiveness of menthol versus tobacco e-cigarettes at facilitating switching at Week 12. Week 12
Secondary Assessment of respiratory symptoms using spirometry Spirometry summarizing forced expiratory flow (FEF) 25-75% and the American Thoracic Society Questionnaire will assess will assess acute respiratory symptoms experienced by cigarette and electronic cigarette smokers. This will help assess the tobacco harm reduction of electronic cigarettes. Week 12
