PRIMARY outcome

Timeframe: 1 month

Population: Participants were randomized to either continue to smoke their usual cigarettes or to avoid menthol cigarettes. Within each group, participants received, in random order, one month of menthol flavored e-cigarettes and one month of tobacco flavored e-cigarettes. The overall number of participants entered for each outcome therefore represents the total number from both relevant randomization conditions (see Participant flow for details) in whom at least 1 week of data was provided.
