What This Study Found

Among 382 surveyed families, 30.9% reported marijuana smoke incursions while home with their child, with NYCHA (public housing) residents 3.45 times more likely to report exposure compared to other housing types.

Key Numbers

382 surveys analyzed; 30.9% reported marijuana smoke incursions; 33.5% reported tobacco smoke incursions; NYCHA residents had adjusted OR of 3.45 for marijuana smoke exposure (p=0.02); two-thirds viewed marijuana smoke as harmful to their child.

How They Did This

Cross-sectional convenience sample of parents attending 4 pediatric practices in the Mount Sinai Health System (2018-2019), with anonymous questionnaires assessing housing characteristics and smoke incursions.

Why This Research Matters

Children in multiunit housing face involuntary exposure to marijuana smoke that parents cannot easily control, raising environmental health equity concerns especially for families in public housing.

The Bigger Picture

As marijuana legalization expands, policies addressing smoking in multiunit housing increasingly need to account for marijuana alongside tobacco to protect children from involuntary secondhand exposure.

What This Study Doesn't Tell Us

Convenience sample from one health system; self-reported smell does not confirm actual secondhand smoke exposure levels; limited to New York City.

Questions This Raises

  • ?Do children in housing with reported marijuana smoke incursions show detectable THC metabolites?
  • ?Would building-wide smoke-free policies reduce incursion rates?
