Standard Smoking Cessation
Participants in the standard smoking cessation (SC) arm will receive a standard approach to smoking cessation, including smoking cessation counseling supplemented with 10 weeks of combination nicotine replacement therapy (NRT) (nicotine patch plus choice of gum or lozenge) if they are willing to make a quit attempt.
|
Extended Nicotine Replacement Therapy
Participants in the guided maintenance therapy (GMT) arm will receive counseling focused on medication adherence and smoking reduction plus up to 52 weeks of combination nicotine replacement therapy (NRT) (nicotine patch plus choice of gum or lozenge) regardless of their interest in quitting.

Timeframe: Month 3, Month 6, Month 12Population: n=4 deceased participants were excluded from analysis. Missing responses were coded as smokers.
Self-reported and biochemically verified 7-day abstinence. Participants were asked at Month 3, Month 6, and Month 12, "Have you smoked any cigarettes or little cigars, even a puff, in the past 7 days?" They also completed an exhaled carbon monoxide lab test at Month 3, 6 and 12. Biochemical verification= exhaled CO \<=10 ppm. Month 12 biochemically verified abstinence is the primary outcome, and is not reported in this table.

SECONDARY outcome
Timeframe: Month 3, Month 6, Month 12Population: n=4 deceased participants excluded from analysis, non-smokers at each time point excluded
Average number of cigarettes per day over one year, among continued smokers. All participants were asked "During the past 7 days, on those days that you smoked, what was the average number of cigarettes smoked per day?" at Month 3, Month 6, and Month 12. This analysis looks at the number of cigarettes per day among participants who were still smoking.
Outcome measures

Standard Smoking Cessation
n=197 Participants
Participants in the standard smoking cessation (SC) arm will receive a standard approach to smoking cessation, including smoking cessation counseling supplemented with 10 weeks of combination nicotine replacement therapy (NRT) (nicotine patch plus choice of gum or lozenge) if they are willing to make a quit attempt.
|
Extended Nicotine Replacement Therapy
n=197 Participants
Participants in the guided maintenance therapy (GMT) arm will receive counseling focused on medication adherence and smoking reduction plus up to 52 weeks of combination nicotine replacement therapy (NRT) (nicotine patch plus choice of gum or lozenge) regardless of their interest in quitting.
