Contingency Management for Smoking Cessation

In this pilot randomized controlled trial (RCT), the investigator will (1) adapt a known-efficacious extended CM cessation intervention to a novel population and setting, with the ultimate goal of increasing long-term abstinence among homeless adults seeking care in safety net health clinics, (2) develop a corresponding RCT protocol, and (3) conduct a pilot RCT to assess the feasibility and acceptability of the RCT. If the pilot RCT is feasible and acceptable, the investigator will test the adapted intervention in a subsequently-funded, full-scale RCT. Primary Objectives: Assess feasibility and acceptability of a CM intervention through: 1. Measuring biochemically-verified point prevalence abstinence at 6 months follow-up. 2. Measuring participant adherence to the protocol. 3. Gathering information on the number of visits attended. 4. Assessing the retention protocol. Secondary Objectives Assess feasibility and acceptability of a CM intervention through: 1. Biochemically-verified 7-day point months follow-up at 3 months. 2. Prolonged abstinence at 3 months and 6 months follow-up. 3. Point-prevalent abstinence at 12 months
