Sponsor's own description

The prevalence of smoking in the homeless population (70%) is over 4 times that of the general population (15%). Homeless adults have not experienced similar declines in tobacco use as the general population has over the past three decades. Homeless adults are interested in smoking cessation and make quit attempts, but are less successful in quitting smoking than the general population. Trials of group behavioral counseling and pharmacotherapy for smoking cessation have not led to substantial long-term abstinence (i.e., abstinence for 6 months or more), suggesting that these interventions alone are insufficient to improve quit rates among homeless adults. Many homeless adults seek health care in safety net clinics; these clinics could bring cessation interventions to scale. Contingency management is a powerful behavior change intervention that reinforces positive health behaviors through the provision of modest incentives (e.g., cash). In this pilot randomized controlled trial, the investigator will test the feasibility and acceptability of a contingency management intervention that provides incentives for smoking cessation for people experiencing homelessness.
