Trial outcomes
Primary outcomes
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.
Secondary outcomes
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.
Amount of e-liquid consumed
E-liquid consumed will be measured in both groups as a measure of acceptability of menthol versus tobacco e-cigarettes.
