California lawmakers have sent Governor Gavin Newsom a sweeping measure that would outlaw hemp-derived products such as those containing delta-8 and delta-10 THC from being sold anywhere but licensed cannabis stores.

Assembly Bill 8, sponsored by Assembly Majority Leader Cecilia Aguiar-Curry, has cleared both chambers with overwhelming support. The Senate voted 37 to 0 on September 12, followed by a 73 to 1 Assembly vote to concur with amendments a day later. If enacted, the law will take effect on January 1, 2028.

The legislation would bar synthetic cannabis products and hemp-derived intoxicants from being sold in smoke shops, gas stations and convenience stores, requiring them instead to be integrated into the state’s licensed cannabis system. Only CBD isolate would remain exempt. The bill also grants state and local agencies expanded authority to inspect, seize and destroy illegal products.

Supporters say the measure is critical for public health and youth safety. “A.B. 8 seeks to protect public health by eliminating access to intoxicating hemp products outside of authorized dispensaries,” said Senator Angelique Ashby. Newsom has also backed similar efforts, having issued emergency rules in 2024 that restricted hemp products with detectable THC and set a minimum purchase age of 21.

Industry groups like the California Cannabis Operators Association (CaCOA) argue the bill levels the playing field for licensed businesses that face steep taxes and regulations.
