 Primary Outcomes: The primary outcome measure will be the point-prevalence of smoking abstinence by self-report for the 7 days prior to assessments, obtained at months 3, 6, 9, and 12 following randomization to study conditions. Verification of smoking abstinence will be obtained by CO readings abstinence 10 ppm obtained at each assessment interval. Salivary cotinine levels abstinence 20 ngml will be measured to verify abstinence at months 9 and 12 only, as subjects may still be using nicotine replacement medicines at earlier assessment intervals, confounding cotinine assays.
