Controlled · selected local policies
SB 58 was vetoed in 2023. AB 1103, enacted in 2025, changed review procedures for authorized controlled-substance research; it did not legalize possession or create public access. AB 2489 is a 2026 research proposal still in committee, not current law. Some cities have local enforcement-priority policies, but those policies do not legalize statewide conduct or commercial sale.
What local policy means
California has documented municipal actions in Oakland, San Francisco and Santa Cruz. Those actions affect local priorities only; they do not create statewide legalization, licensed retail, or medical suitability.
