Title: A Combination of Scheduled Reduced Smoking With Varenicline to Enhance Cessation
Brief Summary: This study has three main aims. Aim 1: To provide initial data on the efficacy of combined Scheduled Gradual Reduction (SGR) and Varenicline (VN) for smoking cessation, by assessing abstinence and levels of smoking at 2 time points (4 and 12 weeks post quit). Aim 2: To explore the possibility that SGR+VN will be particularly efficacious among smokers with higher background levels of Cue Reactivity (CR), as assessed at the start of the study, using a classic experimental smoking CR paradigm. Aim 3: To explore possible mechanisms underlying the effects of SGR+VN, by assessing potential mediators (i.e., self-efficacy, cue-induced cravings) of treatment effects.
