Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The Investigators propose a randomized, placebo-controlled trial to test the hypothesis that varenicline added to group behavioral and texting support will be well tolerated and improve vaping cessation rates among nicotine dependent adolescents who vape, do not smoke regularly, and are willing to try treatment to stop vaping compared to placebo added to group behavioral and texting support. The study will consist of a three-arm randomized, placebo-controlled, parallel-group study of (1) varenicline up to 1 mg bid for 12 weeks added to behavioral and texting support compared with (2) behavioral and texting support and placebo and (3) monitoring only. The primary comparison will be of vaping cessation rates in those assigned to varenicline vs placebo.To do this, the investigators propose to enroll 300 adolescents aged 16-25 who meet eligibility criteria.
