CA AB8

Beginning January 1, 2026, industrial hemp raw extract can only be incorporated into food, beverages, or dietary supplements if it is CBD or CBN isolate with greater than 99% purity and contains no tetrahydrocannabinols or synthetic cannabinoids

Prohibits the sale of hemp flower, hemp prerolls, inhalable cannabis products containing THC derived from industrial hemp, and products containing synthetic cannabinoids within California

Redefines "industrial hemp" to use total THC concentration (including both delta-9 THC and THCA) rather than just delta-9 THC, with the 0.3% dry-weight limit, effectively expanding what qualifies as regulated cannabis

Prohibits tobacco and cigarette retailers from possessing or selling cannabis products at their licensed locations, with penalties including fines up to $10,000 and license revocation for repeat violations

Authorizes the California Department of Tax and Fee Administration and law enforcement to seize products presumed to be cannabis based on cannabinoid content, and subjects such products to the cannabis excise tax plus a 25% penalty
