Participants were asked to indicate on a 12-item scale how smoking made them feel in the prior 30 days on a scale from 1 (Not at all) to 7 (Extremely). Higher values indicated that smoking was a more positive experience for 10 of 12 items. Two items were reverse coded. Change in reinforcing effects of smoking was calculated as Follow-up score (6 month) - Baseline Score.","dispersionType":"Standard Deviation","groups":[{"description":"Patients receive oral varenicline once daily on days 1-3 and twice daily thereafter for a total of 6 months or when a comfortable level of smoking abstinence is reached.\n\nvarenicline: Given orally","id":"OG000","title":"Arm I"},{"description":"Patients receive oral varenicline placebo once daily on days 1-3 and twice daily thereafter for a total of 6 months or when a comfortable level of smoking abstinence is reached.\n\nplacebo: Given orally","id":"OG001","title":"Arm II"},{"description":"Patients receive a nicotine patch, with doses tapering over time for a total of 26 weeks.
