Different versions of the question were asked for current (past 30-day) vapers who had tried to quit in the past year, former vapers (ever vaped but not in the past year), and experimental vapers (vaped in the past year but not in the past 30 days), and combined here. Respondents could select all options that applied; percentages do not add to 100.
Response option added in Wave 2
Asked only of respondents who were smokers
