What this trial studies

This study aims to implement smoke-free policies in subsidized housing to reduce tobacco use and related health disparities. It involves a wait-list cluster randomized controlled trial where residents from 24 subsidized housing sites in Northern California will participate in an intervention designed to promote smoke-free homes and access to smoking cessation services. The study will evaluate the effectiveness of this intervention on residents' adoption of smoke-free homes and biochemically-verified tobacco abstinence after six months, as well as its cost-effectiveness and stakeholder perspectives on its scalability.

Who should consider this trial

Good fit: Ideal candidates are current smokers living in subsidized housing who expect to reside there for at least 12 months and can communicate in English, Spanish, Cantonese, Mandarin, or Vietnamese.

Not a fit: Patients who do not smoke or who have contraindications to study-related procedures will not benefit from this study.

Why it matters

Potential benefit: If successful, this initiative could significantly reduce tobacco use and improve health outcomes among residents of subsidized housing.

How similar studies have performed: Previous studies have shown that smoke-free home interventions can be effective, suggesting potential success for this adapted approach.
