Effective January 2, 2020 these chemicals are now known to the State to cause cancer and cause reproductive toxicity. 

At a public meeting on December 11, 2019, the Developmental and Reproductive Toxicant Identification Committee (DARTIC) in its official capacity as the “state’s qualified experts” determined that cannabis (marijuana) smoke and Δ9-tetrahydrocannabinol (Δ9-THC) were shown to cause reproductive toxicity based on the developmental endpoint. Regulations for the listing of chemicals by the DARTIC are set out in Title 27, California Code of Regulations, section 25305(b)(1).
