After the intervention, all subjects will be reassessed by scripted telephone interviews at 6 and 12 months (see attached). Each telephone call will take approximately 10 minutes. Nurses/health educators will be blinded to group assignment as they made follow-up calls. Initial questions assess smoking status and categorize each subject into one of three categories: nonsmoker (had not smoked since the initial counseling session or the last telephone call), relapser (had smoked since the initial counseling session or the last telephone call but not on a continuous basis), or continuous smoker (had smoked daily for the past 7 days). After each assessment, a saliva sample collection kit will be mailed out to the non-smoking participants with instructions and a postage-paid envelope for return. Participants who have not returned their cotinine within 15 days will be contacted by telephone.
