N. Sample 14) European American smokers who successfully vs unsuccessfully quit smoking in trials in Rhode Island: Participants engaged in a ten week, double-blind placebo controlled trial of placebo or bupropion (150 mg/day for the first 3 days, then 300 mg/day) with a target quit date one week following initiation of drug or placebo [119]. Sixty individuals with biochemically-confirmed abstinence for at least the 7 days prior to both the end of treatment and 24 week assessments were contrasted with 90 unsuccessful quitters who were not abstinent at either time point.
