A Prospective Trial of Varenicline and Incentives for E-cigarette Cessation in Adults Who Co-use Cannabis
Medical University of South Carolina
Summary
The purpose of this study is to better understand tobacco outcomes using a commonly prescribed stop smoking medication (varenicline) and financial incentives for adults who also use cannabis. Varenicline is not FDA approved for e-cigarette cessation, but is FDA approved for cigarette cessation. Investigators are also interested in how cannabis/marijuana and tobacco interact during a tobacco quit attempt. All participants will receive e-cigarette cessation treatment for 12 weeks. To qualify, participants must be between the ages of 18-40 and use both e-cigarettes and cannabis. Participants do not need to be interested in quitting cannabis to qualify. This study is being conducted at three sites: the Medical University of South Carolina in Charleston, SC, Behavioral Health Services in Pickens, SC, and MUSC Lancaster in Lancaster, SC.

Despite high rates of co-use, there is little consensus regarding treatment recommendations for this population and an understanding of the impact of co-use on successful cessation. The literature on the impact of co-use on tobacco…
