Extended Support Program for Tobacco Cessation Among Adults Experiencing Homelessness in California

What this Trial Is About

This research aims to study tobacco use and provide tobacco treatment among people experiencing homelessness in California, specifically in San Francisco and Los Angeles. The study focuses on verifying tobacco abstinence through biochemical methods, including expired carbon monoxide CO measurements, and evaluates both short-term and longer-term tobacco abstinence outcomes. It also looks at reductions in smoking and the longest duration of abstinence as secondary goals. Participants will be randomly assigned to one of two groups. The intervention group receives six months of pharmacist consultation, monthly nicotine replacement therapy NRT which may include patch, gum, or lozenge forms, and wellness coaching delivered by phone weekly to monthly addressing tobacco use and related life challenges. The control group receives pharmacist consultation and monthly NRT for three months only. Follow-up visits occur at one, three, and six months to monitor progress. Throughout the study, participants provide CO samples to biochemically confirm smoking status and complete questionnaires. Researchers measure attendance at coaching sessions, use of NRT, and tobacco abstinence at six months as primary outcomes. Secondary outcomes include abstinence at three months and reductions in CO levels. The total study participation duration includes follow-ups up to six months, with ongoing assessment of tobacco use and wellness support.
