Adults 21+ may possess cannabis under California's Medicinal and Adult-Use Cannabis Regulation and Safety Act.

What this label does—and does not—mean

Adults 21+ have legal possession under state law; limits, public-use rules, local rules, and retail availability still vary. It does not answer public use, driving, employment, housing, federal property, tribal jurisdiction, or a city's business rules.

Possession and use

Up to 28.5 grams of cannabis and 8 grams of concentrated cannabis.

  • Public consumption can remain prohibited even when possession is legal.
  • Never drive, bike in traffic, boat, or operate machinery while impaired.
  • Keep products in their original package and outside the passenger area when transporting within the state.
  • Local ordinances and property policies can add restrictions without changing statewide status.

Home cultivation

Up to 6 plants per private residence, subject to secure cultivation and local rules.

Plant counts are only the first layer. Lease terms, owner permission, visibility, locked-area rules, nuisance law, processing limits, and possession of harvested cannabis can each change the practical answer.

Medical access

Medical and licensed adult-use markets.

A recommendation, registry card, out-of-state card, or diagnosis does not create identical rights everywhere. Confirm patient eligibility, reciprocity, purchase limits, approved forms, renewal rules, and caregiver rights with the official program.

Buying and retail status

Licensed adult-use retail; cities and counties may restrict businesses.

Use the state regulator's live license lookup where available. A website, delivery claim, hemp label, social-media account, or storefront sign is not proof of a marijuana license.

What you need to buy legally

ADULT-USE / RECREATIONAL

No recreational card required

There is no state recreational-consumer card application. Adults 21+ may use a valid, unexpired government-issued photo ID at a licensed adult-use retailer where sales are operational.

MEDICAL PROGRAM

Certification required; no separate card

How to qualify: Meet with an eligible practitioner and obtain the state-recognized written certification or recommendation; there is no separate patient-card application.

A current qualifying physician recommendation can support medical purchasing. The county-issued MMIC is voluntary but can provide additional identification and tax benefits.

At the dispensary: Bring the current certification or recommendation and a valid government-issued photo ID.

Do not buy a generic “medical card” online

Only the credential, certification, recommendation, or registry process recognized by this state can authorize medical purchasing. Private evaluation services do not replace state approval where approval is required.

Travel, work, housing, and federal edges

  • STATE LINESDo not take cannabis across a state border—even between two adult-use states.
  • FEDERAL PROPERTYState permission does not control federal buildings, lands, installations, or federal transportation rules.
  • WORKLegal possession does not guarantee workplace use or protection from a lawful drug policy.
  • HOUSINGSmoking, cultivation, and possession can be restricted by leases, federal housing rules, or property policy.
  • TRIBAL LANDTribal law and jurisdiction can differ from the surrounding state; verify with the relevant tribal authority.
