Young Adult Tobacco/Nicotine and Cannabis Co-use

Research staff will provide skills-based counseling at remote weekly visits, starting at Day 0. Counseling sessions will be brief (\~5-10 minutes) and will focus on strategies for preparing for the quit attempt, dealing with triggers, refusal skills, and enhancing motivation.

Contingency management (CM): CM will be provided to all study participants to promote abstinence from all nicotine products. Incentives for abstinence (based on submission of a negative cotinine sample) will be provided on an escalating schedule during treatment (Days 8-84).

All participants will be provided with evidence-based nicotine cessation resources. For those who are vaping nicotine, participants will be provided information for This is Quitting (SMS text-based program). For those who are primarily smoking cigarettes, NCI's QuitSTART (mobile app, web content), as well SmokefreeTXT (SMS-text based program), will be recommended, potentially in addition to This is Quitting for those using multiple products. These resources provide real time monitoring of nicotine use, mood, triggers and lapses.
