- Healthy Living:Marijuana Causes Cancer, California Regulators Say
Friday, June 19, 2009
SAN FRANCISCO — Marijuana smoke has joined tobacco smoke and hundreds of other chemicals on a list of substances California regulators say cause cancer.
The ruling Friday by the Office of Environmental Health Hazard Assessment likely will force pot shops with 10 or more employees to post warnings. Final guidelines are expected by the time warning requirements take effect in a year.
The listing only applies to marijuana smoke, not the plant itself.
