Condition or disease
Drug: vareniclineDrug: placebo
This pilot study will utilize a two group randomized design. Adult smokers who are motivated to quit smoking will be randomized to one of two treatment groups. Both groups will receive brief support counseling. During a one-week baseline and the 4-week pre-quit period smoking rate, smoking satisfaction, withdrawal, and craving will be assessed on a daily basis.

Change in cigarettes per day from Week 2 to Week 5
Secondary Outcome Measures
Rates of Smoking Cessation. [ Time Frame: 12 weeks after quit date. ]
To parallel most clinical trials of varenicline, we focused on CO-verified (<11 parts per million) continuous abstinence (not even one puff) during the final 4 weeks of treatment (i.e., post-quit weeks 8 through 11). Participants lost to follow-up were coded as smokers.
