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.
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.
Inclusion Criteria: * English literate * Report cigarette smoking, and e-cigarette use for at least the past 3 months * Smoke 5 or more cigarettes per day * Report e-cigarette use for at least 14 days in the past month * Interested in quitting both products in the next month and willing to set a quit date. Exclusion Criteria: * Vulnerable Populations: Investigators will not be enrolling vulnerable populations, specifically pregnant women, children, prisoners, or institutionalized individuals * Investigators also will not enroll participants incapable of providing their own consent.

Varenicline prescription will follow the standard induction period: varenicline 0.5 mg once per day for Days 1-3, varenicline 0.5 mg twice per day for Days 4-7, then varenicline 1 mg twice per day (when varenicline reaches peak efficacy for tobacco cessation). Participants will remain on varenicline for 12 weeks total. Dose adjustments (e.g., reduction to 0.5 mg twice per day if 1 mg is not well tolerated) will be allowed at the discretion of the clinical pharmacist/APRN/physician.
Tobacco Treatment Service clinicians will deliver weekly counseling sessions, monitor participants for adverse events, and record participants' weekly cigarette and e-cigarette use. At the first counseling session clinicians will review medication proper use instructions, and potential side effects and strategies to address them at the first counseling session. Study medication refills will be distributed at 4-week intervals. Sessions will focus on quit plan preparation, supportive and practical cessation counseling, resetting quit dates, and relapse prevention.
The booklet includes information on how to reduce and quit both cigarettes and e-cigarettes on their own, how to prevent relapse, how to set a quit date, and how to enroll in text-based support resources.
