California Environmental Protection Agency – Pot Smoke Causes Cancer
The Safe Drinking Water and Toxic Enforcement Act of 1986. requires that the Governor cause to be published a list of those chemicals “known to the state” to cause cancer or reproductive toxicity. The Act specifies that “a chemical is known to the state to cause cancer or reproductive toxicity … if in the opinion of the state’s qualified experts the chemical has been clearly shown through scientifically valid testing according to generally accepted principles to cause cancer or reproductive toxicity.”
The lead agency for implementing Proposition 65 is the Office of Environmental Health Hazard Assessment (OEHHA) of the California Environmental Protection Agency. The “state’s qualified experts” regarding findings of carcinogenicity are identified as the members of the Carcinogen Identification Committee of the OEHHA Science Advisory Board.
OEHHA announced the selection of marijuana smoke as a chemical for consideration for listing by the CIC in the California Regulatory Notice Register on December 12, 2007, subsequent to consultation with the Committee at their November 19, 2007 meeting. At that meeting, the Committee advised OEHHA to prepare hazard identification materials for marijuana smoke.
At their May 29, 2009 meeting the Committee, by a vote of five in favor and one against, found that marijuana smoke had been “clearly shown through scientifically valid testing according to generally accepted principles to cause cancer.”
