California Cannabis Laws
Cannabis is legal in California for both medicinal and adult use. Two key laws define today’s framework: Proposition 64, the Adult Use of Marijuana Act (AUMA), which legalized recreational cannabis, and the Medicinal and Adult Use of Cannabis Regulation and Safety Act (MAUCRSA), which combined prior medical cannabis laws into one statewide system. Together, these laws regulate cannabis sales, cultivation, licensing, and taxation across the state.
Who Can Use Cannabis?
- Medicinal Use: 18 or older with a physician’s recommendation
- Adult Use: 21 or older
Cities and counties may have stricter rules than the state. Always check your local government website for additional regulations in your area.
Medicinal vs. Adult Use
Medicinal patients with a doctor’s recommendation may:
- Possess larger amounts of cannabis
- Purchase more each day if needed for treatment
- Grow more plants at home with physician approval
Resources for patients and caregivers are available from the Department of Cannabis Control (DCC).
Where You Can Use Cannabis
Cannabis use is allowed on private property, but not in public places such as restaurants or bars. Smoking or vaping is prohibited where tobacco use is banned, and within 1,000 feet of schools, day care centers, or youth centers while children are present. Property owners and landlords may also prohibit use on their property. Most hotels do not allow cannabis use indoors, so always check policies before your stay.
Important note: cannabis is still illegal under federal law. That means you cannot bring it onto federal lands like national parks, or take it across state lines.
Growing Cannabis at Home
Adults 21 and older may grow up to six plants at home. If you process cannabis, you cannot use volatile solvents such as butane or propane. Some local governments require home grows to be indoors or permitted, so check local regulations before starting.
Driving With Cannabis
It is illegal to have an open container of cannabis in a vehicle. Cannabis must be stored in a sealed package or kept in the trunk. Driving under the influence of cannabis is prohibited and can result in a sobriety test, whether you are operating a car, boat, or other vehicle.
Buying Cannabis
All cannabis retailers must be licensed by the DCC. Licensed shops must:
- Verify buyers are of legal age
- Sell only tested products
- Accurately label THC and CBD content
Some unlicensed shops may appear legitimate but sell untested products that could contain mold, pesticides, or other contaminants. To confirm a store is licensed, use the DCC license search tool or scan the QR code on the shop’s license certificate.
Reporting Suspicious Activity
If you suspect a store is unlicensed or violating cannabis laws, you can file an anonymous complaint with the DCC. Provide as much detail as possible to support enforcement efforts.
