As of January 3, 2021, the one-year grace period to comply with the California Prop 65 Clear and Reasonable Warning requirements for delta-9-tetrahydrocannabinol (known as THC) came to a close and the enforcement period has now begun. OEHHA, the enforcing agency for Prop 65, added THC to the Prop 65 chemicals list last year on January 3, 2020. It is listed as a chemical known to cause reproductive harm.
As many in the CBD-industry are likely aware, Cannabis (Marijuana) Smoke was added to the Prop 65 chemicals list as a carcinogen in 2009 and enforcement of the Clear and Reasonable Warning requirements began thereafter. However, in January 2020, it was also classified as a reproductive toxin. Enforcement of the Clear and Reasonable Warning requirements specifically for reproductive toxicity from CBD (Marijuana) Smoke began on January 3, 2021 as well.
Currently, there are no safe harbor levels for THC and CBD (Marijuana) Smoke. Therefore, any detectable amount of THC (or Cannabis / Marijuana Smoke) in a product may require a Prop 65 warning. For THC in particular, this applies notwithstanding the fact that federal law does not regulate CBD products that contain 0.3% or less THC by dry weight (i.e., cannabis containing less than 0.3% THC is considered to be “hemp” as opposed to “marijuana” according to 7 U.S.C. § 1639o(1)). Therefore, for products that result in any exposure to THC, a Prop 65 warning for reproductive harm may still be required, and now for Cannabis (Marijuana) Smoke products, an additional warning for reproductive harm (on top of cancer) may be required.
