Outcome Measures

Primary Outcomes (1)

  • Number of Participants Completing Continuous Four-week Abstinence From Smoking Between the 8-week and 11-week Post Quit Day Visits

    This will be determined by a composite of self-report at the 11-week study visit of no smoking between the 8-week and 11-week visits and expired air carbon monoxide (CO) \<10 ppm (measured at the 11-week study visit). An intent-to-treat criterion will be used, whereby drop-outs are considered to be non-abstinent.

    Period between 8-week and 11-week visits post target Quit Day

Secondary Outcomes (2)

  • Number of Participants Completing Seven-day Point Abstinence From Smoking at 6 Months Post Quit Day

    6 months post Quit Day

  • Number of Participants Completing Continuous Abstinence From Smoking Between Quit Day and 11-week Post Quit Day Visit

    Quit Day to 11-week post Quit Day study visit

Other Outcomes (1)

  • Change in Smoking Withdrawal Symptoms

    Quit Day and 1 week, 3 weeks, 7 Weeks, 11 Weeks and 6 months post Quit Day

Study Arms (2)

Chantix

EXPERIMENTAL

For the first 3 days after being switched from Nicotine Replacement Therapy (NRT) (occurring at one week after initiation of nicotine patch treatment, one week before the target Quit Day), smokers in this group will receive treatment with Chantix 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-week active treatment duration.

Drug: ChantixDrug: Nicotine patches

Chantix + Zyban

EXPERIMENTAL

For the first 3 days after being switched from NRT (occurring at one week after initiation of nicotine patch treatment, one week before the target Quit Day), smokers in this group will receive treatment with Chantix 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 Zyban at a dose of 150mg once per day. Subsequently, the dose of Chantix will be 1 mg twice per day and the dose of Zyban will be 150 mg twice per day for the remainder of the 12-week active treatment duration.
