Prop 65: Important changes for California Cannabis Manufacturers

The California Office of Environmental Health Hazard Assessment (OEHHA) has made significant changes to prop 65 warnings for companies involved with cannabis, voting to add both cannabis smoke and THC to the list of substances known to cause developmental toxicity. THC is the principal psychoactive cannabinoid in marijuana. Any product that includes THC and cannabis smoke will need to include the warning for both cancer and reproductive toxicity.

What does this mean for my cannabis products today? 

OEHHA spokesperson Sam Delson stated that Prop 65 allows a 12 month grace period for adding labels to products. Cannabis manufacturers and retailers will not be required to sell products with the dual harm warning until late 2019. During this time period, OEHHA may determine a safe level of exposure to THC and cannabis smoke. Fingers crossed they’ll figure that out.
