Arms and Interventions

Arm Intervention/Treatment
Active Comparator: varenicline

For the first 3 days after being switched from Nicotine Replacement Therapy (NRT) occurring at one week before the target quit date, smokers in this group will receive varenicline at a dose of 0.5 mg once per day followed by 0.5 mg twice a day for the remaining 4 days of that week. Subsequently, the dose will be 1 mg twice per day, and will remain at that dose for the remainder of the 12 weeks. During the time they receive varenicline, smokers in this group will also receive placebo bupropion and placebo patches.

Drug: Varenicline
Other Names:
  • Chantix
  • Drug: Nicotine patches
    Other Names:
  • Nicoderm
  • Other: Placebo bupropion

    Other: Placebo patch

    Active Comparator: NRT (nicotine patches only)

    21 mg/24 h for 2 weeks before the quit date and 7 weeks after the quit date, 14 mg/24 h for 2 weeks, and 7 mg/ 24 h for 2 weeks. After the 1st week, smokers in this group will also receive placebo bupropion and placebo varenicline.

    Drug: Nicotine patches

    For the first 3 days after being switched from Nicotine Replacement Therapy (NRT) occurring at one week before the target quit date, smokers in this group will receive varenicline at a dose of 0.5 mg once per day followed by 0.5 mg twice a day for the remaining 4 days of that week plus bupropion at a dose of 150mg once per day. Subsequently, the dose of varenicline will be 1 mg twice per day and the dose of bupropion will be 150 mg twice per day, and will remain at that dose for the remainder of the 12 weeks. During the time they receive varenicline and bupropion, smokers in this group will also receive placebo patches.

    Outcome Measures

    Primary Outcome Measures

    1. The Amygdala, Anterior Insula, and Medial Prefrontal Cortex Scans Will be Compared to Evaluate Significant Differences [change from baseline in whole brain blood-oxygen-level dependent (BOLD) contrast sensitive functional magnetic resonance imaging (fMRI) images collected during a cue-reactivity task following 2 weeks of pre-quit treatment]

      Mean blood-oxygen-level dependent (BOLD) contrast sensitive functional magnetic resonance imaging (fMRI) cue-reactivity signal following 2 week pre-quit treatment, controlling for baseline cue-reactivity.

    Secondary Outcome Measures

    Participant Flow

    Recruitment Details
    Pre-assignment Detail Of the 282 participants who were consented and screened, 191 were screen fails, 2 withdrew voluntarily before being assigned to a study arm, and 13 were lost to contact between screening and the first study visit. Therefore, only 76 participants were randomized and started the study.
