Adult-Use Legal

Quick Facts

Public Possession

1 oz (28.5g) flower; 8g concentrate

Home Possession

8 oz (227g) flower

Transport Rules

Keep cannabis in a sealed, closed container in the trunk or locked glove compartment. Never accessible to driver or passengers while the vehicle is moving. Crossing state lines — including into Nevada or Oregon — is a federal crime regardless of legality in both states.

Medical Reciprocity

No Reciprocity

California does not formally recognize out-of-state medical cannabis cards. Out-of-state patients must purchase from adult-use retail like any tourist.

Dispensaries & Purchasing

Licensed adult-use dispensaries statewide. Delivery legal in most jurisdictions. Some cities have opted out (no local dispensaries).

Purchase limit: 1 oz flower or 8g concentrate per transaction

Where You Can Consume

Illegal in public spaces. Same rules as tobacco — no smoking or vaping in parks, beaches, sidewalks, or within 1,000 feet of schools while minors are present. Hotels may designate smoking rooms.

Never Cross State Lines with Cannabis
