Legalization of medicinal and adult-use cannabis in California has fomented a surge of seed-to-sale companies angling to lure market share from a sea of customers. The water may soon be agitated, however, by the Office of Environmental Health Hazard Assessment (OEHHA). OEHHA is the lead California agency that oversees implementation of Proposition 65, formally known as the Safe Drinking Water and Toxic Enforcement Act of 1986. OEHHA recently announced that it has selected cannabis (marijuana), marijuana (cannabis) smoke, cannabis extracts, and delta-9-Tetrahydrocannabinol (THC) for review for possible listing under Proposition 65 as chemicals that cause reproductive toxicity. If the Developmental and Reproductive Toxicant Identification Committee (DARTIC) determines that these chemicals cause reproductive toxicity based upon “scientifically valid testing according to generally accepted principles,” marijuana in its various forms will likely join a list of more than 900 chemicals known to the state to cause cancer, birth defects, or other reproductive harm. Companies that cultivate, distribute, and/or sell marijuana and products containing marijuana in California would then be required to warn consumers—and possibly employees and passersby—that exposure to these listed chemicals can cause reproductive harm.

Notification and response levels are non-binding, health-based advisory levels for contaminants in drinking water where maximum contaminant levels (MCLs) have not been promulgated. Establishment of notification and response levels often is the DDW’s first step toward adopting binding MCLs.

These new regulations, which allocate responsibility for providing warnings on consumer products sold in California and include new criteria for “safe harbor” warnings, become operative on August 30, 2018.
