First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested two approaches to help people living in public housing smoke less and reduce secondhand smoke. One approach offered one-on-one support to smokers to help them cut back or quit. The other aimed to get all residents in a building to support smoke-free rules. The study included 405 participants from buildings in Manhattan and the Bronx. Researchers measured changes in cigarettes smoked per day, cotinine levels, and secondhand smoke exposure.
