Study start date: July 1, 2019

Actual date on which the first participant was enrolled.

The goals of this project include evaluating within-subject changes in cigarette satisfaction and smoking behavior after switching from menthol cigarettes and investigating whether outcomes differ between subjects based on use of menthol vs. tobacco flavored e-cigarettes. Within-person changes in cigarette satisfaction and smoking behavior will be assessed during the last week of the non-menthol cigarette smoking period compared to the menthol cigarette smoking period. Preference and use of both the cigarette and e-cigarette products during the switching period will be compared and the extent to which menthol flavored (vs. tobacco) e-cigarettes are preferred among menthol smokers will be evaluated.
