A Preliminary Test of Concurrent vs. Sequential Cessation of Dual Cigarette and E-cigarette Use on Behavior, Tobacco Toxicant Exposure, and Health Effects
- Study HIC#:2000035713
- Last Updated:04/25/2024
The purpose of this research study is to understand whether concurrent treatment for cigarettes and e-cigarettes in which an individual quits both products at the same time (QUIT-C) or sequential treatment in which an individual quits cigarettes first followed by e-cigarettes is more effective for quitting both products. The study will also compare the effect of treatment on health-related biomarkers. All participants will receive varenicline, a medication used to treat tobacco use dependence, counseling, and cessation resources (i.e., links to text-based support, self-change booklet). Varenicline helps to reduce cravings for tobacco use and decreases the pleasurable effects of cigarettes and other tobacco products.

Trial Purpose and Description
Inclusion/exclusion criteria will be determined via initial online screening and then confirmed with tele-video/phone call final screening. Non-pregnancy verification will be ascertained via remote pregnancy test.
All participants will be asked to provide assessments (as described below) throughout the sampling process to assess cigarette smoking and e-cigarette use behavior, varenicline use, and use of cessation resources.
This is a 12 week, open-label study of varenicline.
