Is cannabis legal in California?

Recreational & medical

Yes. Cannabis is legal for adults 21 and over in California, for both recreational and medical use.

What this status means: Recreational (adult-use) status means adults at or above the legal age may possess cannabis within state limits without a medical card, and a licensed retail market is authorized. State rules still control amounts, home cultivation, and where use is allowed, and it stays illegal to cross state lines with cannabis.

The facts, with sources

Possession
Up to 28.5 g (1 oz) flower and 8 g concentrate for adults 21+; no penalty within limits (Health & Safety Code § 11362.1)
Decriminalized
Yes
Home cultivation
Yes Up to 6 living plants per residence (any number of adults 21+), in a locked area not publicly visible. Localities may reasonably regulate but cannot ban indoor grows. Medical patients may exceed 6 with a physician recommendation.
Medical reciprocity
No California does not recognize out-of-state medical cards; its MMIC program (SB 420) is CA-residents-only. Largely moot: any adult 21+, resident or visitor, may buy and possess adult-use quantities regardless of medical status.

How federal law applies

Cannabis (termed "marijuana" in federal law) generally remains a Schedule I controlled substance. Only FDA-approved products and cannabis held under a qualifying state medical license have been moved to Schedule III (rule effective April 28, 2026); the broader Schedule I-to-III transfer is not finalized and remains pending in DEA's expedited rescheduling rulemaking.

Under the December 18, 2025 Executive Order on "Increasing Medical Marijuana and Cannabidiol Research," DOJ/DEA announced on April 23, 2026 that it was placing FDA-approved cannabis products and state-licensed medical cannabis into Schedule III (rule effective April 28, 2026) but left all other cannabis (unlicensed adult-use, bulk material, and synthetic THC) in Schedule I, and opened an expedited rulemaking (Federal Register, April 28, 2026) to consider rescheduling more broadly. A DEA administrative law judge began hearing evidence in that rulemaking on June 29, 2026; as of this site's last verification of this section, no final rule rescheduling cannabis generally had been issued. State-legal cannabis programs are unchanged by these developments and continue to operate under their own state laws.

A note on terminology: federal statute uses "marijuana" (spelled "marihuana" in the Controlled Substances Act) for what scientific and healthcare literature calls cannabis. This site uses "cannabis" except when quoting official sources.

Methodology, sources & AI use

Each jurisdiction was researched against at least two sources: the controlling state statute or state agency page, cross-checked against an aggregate policy tracker. Every state was then independently re-derived in a second, blind research pass, and every disagreement and every nuanced case (low-THC programs, varies flags, recent law changes, DC) was resolved by a third review against primary sources. Access dates are recorded per source and a verification date is shown per state. US territories are not yet covered.

How AI was used: This dataset and page were built with substantial help from AI (Anthropic's Claude), directed and reviewed by a human editor. AI research agents gathered the statutes and agency pages cited for each state; a second, independent AI pass re-derived every state's facts without seeing the first pass; and a third pass resolved all disagreements against primary sources. Every cited link was then opened and checked in a real web browser, and dead or outdated citations were corrected by hand before publication. AI can still make mistakes, and laws change quickly.
