Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Hypotheses: We hypothesize that greatest treatment effects will be observed in the bupropion SR+varenicline group followed by varenicline+placebo and bupropion SR+placebo groups.
