What This Study Found

67% of residents reported smelling marijuana smoke in their home over the past year, compared to 60% for cigarette smoke. Smoking status and smelling secondhand tobacco smoke were both strong predictors of smelling secondhand marijuana smoke. Nearly two-thirds of residents perceived smoking marijuana and secondhand marijuana smoke as harmful to health.

Key Numbers

1,030 participants from 21 buildings. Response rates: 35% NYCHA, 32% Section 8. 67% smelled marijuana smoke. 60% smelled cigarette smoke. ~2/3 perceived secondhand marijuana smoke as harmful.

How They Did This

Cross-sectional survey of residents in 21 subsidized housing buildings in NYC: 10 NYCHA buildings (n=559) and 11 Section 8 buildings (n=471). Surveys collected April-November 2018, prior to smoke-free housing policy implementation.

Why This Research Matters

As marijuana use increases, secondhand exposure in shared housing environments becomes a growing concern, particularly as smoke-free policies may not address marijuana smoke.

The Bigger Picture

Smoke-free housing policies being implemented in public housing authorities target cigarette smoke but may not explicitly cover marijuana smoke, creating a regulatory gap.

What This Study Doesn't Tell Us

Self-reported exposure (smelling smoke, not biomarker-verified). Low response rates (32-35%). NYC housing may not represent other settings. Cross-sectional design.

Questions This Raises

  • ?Should smoke-free housing policies explicitly include marijuana?
  • ?Would edible or vaporized cannabis reduce secondhand exposure in multi-unit housing?
