简要总结
Varenicline is used to treat tobacco use dependence. It helps reduce cravings for tobacco use and decreases the pleasurable effects of cigarettes and other tobacco products. Varenicline has been proven to reduce the desire to smoke cigarettes. This study aims to test whether it shows a similar benefit for individuals who vape and are interested in quitting.
详细描述
Varenicline is a highly efficacious FDA-approved smoking cessation pharmacotherapy. The aim of this study is to examine the effectiveness of varenicline for e-cigarette cessation medication for mono- e-cigarette use in combination with a minimal, self-guided behavior change booklet. This booklet will include general tips for e-cigarettes cessation and information about the free web-based e-cigarette cessation program sponsored by The Truth Initiative and Mayo called "This is Quitting". This study will have an 8-week treatment period and a 4-week follow-up phase. Participants will be randomized to receive an 8-week supply of varenicline or matching placebo (gel capsule filled with cellulose powder) in combination with the self-change booklet. The investigators hypothesize that participants who receive varenicline will have higher rates of e-cigarette cessation.
