Marijuana Smoke Listed Effective June 19, 2009 As Known To The State Of California To Cause Cancer

The Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency is adding marijuana smoke to the Proposition 65 list¹, effective June 19, 2009. 

Marijuana smoke was considered by the Carcinogen Identification Committee (CIC) of the OEHHA Science Advisory Board² at a public meeting held on May 29, 2009.  The CIC determined that marijuana smoke was clearly shown, through scientifically valid testing according to generally accepted principles, to cause cancer.  Consequently, marijuana smoke is being added to the Proposition 65 list, pursuant to Title 27, California Code of Regulations, section 25305(a)(1) (formerly Title 22, California Code of Regulations, section 12305(a)(1)). 

A complete, updated chemical list is published elsewhere in this issue of the California Regulatory Notice Register.

In summary, marijuana smoke is being listed under Proposition 65 as known to the State to cause cancer:
