Title: Relapse Prevention With Varenicline
Brief Summary: This study aims to determine if varenicline (Chantix®), currently used as a smoking cessation aid, will decrease the likelihood of relapse to smoking following a programmed lapse in the laboratory. The hypothesis is that varenicline will reduce the reinforcing effects of smoking and will delay or prevent relapse compared to placebo.
