California Cannabis Laws: Updated Rules for Locals and Visitors

Yes. California is a fully legal recreational and medical cannabis state. Adults 21 and older can possess up to 28.5 grams of flower and 8 grams of concentrate, purchase from licensed dispensaries, and grow up to six plants at home.

Public consumption is still illegal almost everywhere. Use only on private property with the owner's permission, or at a licensed consumption lounge in cities that allow them.

Stricter enforcement against the illicit market and expanded licensed retail. California is tightening rules on unlicensed delivery operations and adding stricter packaging and labeling requirements at the dispensary level.

Several cities, including Los Angeles, West Hollywood, San Francisco, and Oakland, have expanded or refined their consumption-lounge programs. Lounges remain the only legal place to consume in public.

Adults 21+ may possess up to 28.5g of flower and 8g of concentrate at one time. Daily dispensary purchases are capped at the same amounts.

Medical patients with a valid recommendation can possess and purchase higher amounts and are exempt from certain excise taxes.

Yes. Out-of-state visitors 21+ can buy at any licensed dispensary with valid government ID — no California ID required.

Hotels almost always ban indoor cannabis use. Look for explicitly cannabis-friendly accommodations or use a consumption lounge.

Driving under the influence of cannabis is a DUI. Open containers in a vehicle are illegal — keep purchases sealed and in the trunk.

There is no legal THC blood limit; impairment is judged by officer observation and field testing.

Yes. Adults can grow up to six plants per residence, regardless of how many adults live there. Plants must be in a locked, non-public area.

Local cities can ban outdoor cultivation but cannot ban indoor home grows.

California remains one of the most accessible legal cannabis markets in the United States. Stay on private property, buy only from licensed retailers, and never cross state lines with product.
