Participant Flow

This study enrolled adult daily smokers from the Raleigh-Durham region in North Carolina who reported interest in quitting smoking

Eighty-seven participants were enrolled and assessed for eligibility. Thirty-eight of those did not meet inclusion criteria (n=29), or withdrew (n=7) or were lost to contact (n=2) prior to baseline. Forty-nine participants completed the baseline cue-reactivity session and 34 returned for their randomization visit.

MCE+
Three weeks prior to the target quit date, participants will switch to smoking very low nicotine content cigarettes and wear a 21 mg/d nicotine patch. During the 3-week pre-quit period, participants will undergo six, 60 minute sessions during which they will view smoking-related environments and smoke their assigned cigarettes. Following the quit date, participants will quit smoking and wear the nicotine patch for 10 weeks.
MCE- (Control)
Three weeks prior to the target quit date, participants will switch to smoking very low nicotine content cigarettes and wear a 21 mg/d nicotine patch. During the 3-week pre-quit period, participants will undergo six, 60 minute sessions during which they will view nature environments and smoke their assigned cigarettes. Following the quit date, participants will quit smoking and wear the nicotine patch for 10 weeks.

Timeframe: week 1, week 6

Population: Number in each group represents the number of participants who completed the pretreatment phase.

Compliance with smoking VLNCs. Reduction in usual brand (UB) cigarette use over the treatment period will be calculated for each group. Average usual brand cigarettes per day was calculated using the average number for the first 5 days of treatment (week 1) and the average number for the last 5 days of treatment (week 6). Values were calculated as number smoked at W1 minus the number smoked at W6.

SECONDARY outcome

Timeframe: week 3, week 6

Population: represents all participants who completed both week 3 and week 6 assessments

Reduction in total cigarette use over the treatment period will be calculated for each group. Average cigarettes per day was calculated using the average number for the 5 days leading up to week 3 and the average number for the 5 days leading up to week 6. Values were calculated as number smoked at W3 minus the number smoked at W6. Positive values represent a decrease in smoking behavior.
