THC in California

California banned hemp-derived THC products through emergency regulations implemented by Governor Newsom in September 2024, which were made permanent in 2025. The regulations require that industrial hemp food, beverages, and dietary supplements intended for human consumption contain "no detectable THC" per serving, effectively banning delta-8, delta-9, and other hemp-derived THC products from retail sale. While AB 45 (2021) initially created a framework for hemp products, the state moved to close loopholes due to public health concerns about intoxicating products reaching children. Products containing any detectable THC must now be sold through state-licensed marijuana dispensaries only. The California Department of Public Health has expanded enforcement powers to fine non-compliant businesses and seize illegal products, with violations resulting in immediate product removal and potential business closure.
