Active substance: behavioral intervention (counseling and staff training)
What this could lead to: If successful, this could help formerly homeless adults voluntarily adopt smoke-free homes, reducing smoking rates and secondhand smoke exposure in supportive housing.
What could go wrong: This is a completed trial, but results may not apply to all housing settings. The intervention relies on voluntary participation, so some residents may not adopt smoke-free homes.
