On August 8, 2022, the California Office of Environmental Health Hazard Assessment (OEHHA) approved tailored Prop 65 safe harbor warnings for THC and marijuana smoke. While the regulations became effective on October 1, 2022, there was a one-year phase-in period and unlimited sell-through provision for products manufactured and labeled with compliant warnings before October 1, 2023. Therefore, in a few short weeks on October 1, 2023, that grace period ends, and these products will need to be labeled with a compliant warning thereafter.
