Baseline interviews were conducted between January and June 2006. Follow-up 1 interviews were conducted between July and December 2006, follow-up 2 between January and June 2007, follow-up 3 between July and December 2007, follow-up 4 between January and June 2008, and follow-up 5 interviews were conducted between July and December 2008.
Quit is a binary variable comparing respondents who were classified as a former smoker to respondents who were current smokers. Participants who reported having quit smoking at one of the follow-ups were not excluded from further follow-ups. Former smokers were defined as those who smoked more than 100 cigarettes in their lifetime but did not smoke a cigarette in the past 6 months (i.e. since the prior follow-up interview).
Previous brand type information was not collected because this was the baseline interview.
