What We Now Know About Secondhand Marijuana Smoke

We’re excited to share the release of an updated Marijuana Secondhand Smoke Fact Sheet, featuring the latest peer-reviewed studies on the health risks of exposure to marijuana smoke. As the marijuana/cannabis industry pushes for normalizing use in many communities and states, it is critical to understand and share the growing science around exposure to secondhand marijuana smoke, especially when it comes to protecting nonsmokers and the workforce from exposure. 

This fact sheet includes:

  • New evidence on how marijuana smoke affects heart and lung health
  • Updated data on secondhand exposure risks in homes and multi-unit housing
  • Key findings from recent studies on youth and child exposure
  • Recommendations from the 2024 Surgeon General’s Report

Check out the updated fact sheet here.
