SAN FRANCISCO (AP) - 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
Spokesman Sam Delson says the state agency found marijuana smoke contains 33 of the same harmful chemicals as tobacco smoke.
Delson says the findings came from a review of more than 30
California's Proposition 65 requires businesses to warn
consumers of chemicals that cause cancer or reproductive harm.
