Respondents were asked consistently across waves: 1) how many days they smoked cigarettes in the past 30 days; and 2) how many cigarettes they smoked on average on days they smoked in the past 30 days. Based on preliminary analyses of distributions of the data, we examined three primary smoking-related outcomes: past 30-day use (yes/no), use more than 25 days in the past month (yes/no), and average number of cigarettes smoked on days smoked.
