TL;DR
Adults 21+ can carry up to 28.5 grams of flower and 8 grams of concentrate, and grow 6 plants per home. Public use is illegal except in licensed lounges. The cannabis excise tax is 15% through June 2028, plus sales and local taxes.
California was the first state to legalize medical cannabis, with Proposition 215 in 1996. Voters approved recreational use with Proposition 64 in 2016, and licensed adult-use sales began on January 1, 2018. The Department of Cannabis Control (DCC) regulates the market today.
Is weed legal in California?
Yes, for adults 21 and older. Bring a valid ID to any licensed dispensary or delivery service. Visitors can buy too.
How much can you buy and carry?
| Limit | Adults 21+ | Medical patients |
|---|---|---|
| Flower | Up to 28.5 grams (about 1 ounce) | Up to 8 ounces (more with a doctor's recommendation) |
| Concentrate | Up to 8 grams |
Going over the adult limit is a misdemeanor, with up to 6 months in jail and/or a $500 fine.
Where can you use it?
Private property is the place. Using cannabis is illegal in public, including streets, parks, restaurants and cars, and near schools or daycares when kids are present. Landlords and hotels can ban it.
The exception is licensed consumption lounges, which some cities allow. Since 2025, lounges can also sell non-infused food and drinks and host events.
Can you grow cannabis at home?
Yes, no permit needed. Adults 21+ can grow up to 6 plants per residence, not per person, so roommates share the same 6. Plants must be on your own property, secured from minors and not visible to the public. Cities can't ban indoor growing of 6 plants, but they can restrict or ban outdoor growing, so check local rules.
Medical cannabis in California
Patients with a doctor's recommendation can get a state Medical Marijuana Identification Card (MMIC) through their county. The card is optional, but it exempts you from sales tax on cannabis and gives you higher possession limits.
Taxes on cannabis in California
A bill signed in 2025 cut the state cannabis excise tax to 15% from October 1, 2025 through June 30, 2028, reversing a planned increase. On top of that you'll pay regular state and local sales tax (the 7.25% base rate plus local add-ons), and many cities add their own cannabis business tax, which shows up in shelf prices.
Driving, work and housing
- Driving: Driving while impaired is illegal. You also can't have an open container of cannabis in a car, so keep it sealed and out of reach.
- Work: Since 2024, California law generally bars employers from penalizing workers for off-the-job cannabis use or for tests that only detect non-psychoactive THC metabolites. There are exceptions, like construction and federal jobs. Employers can still ban use or impairment at work.
- Housing: Landlords can prohibit smoking and growing.
Old marijuana convictions
Prop 64 let people with past cannabis convictions get them reduced or dismissed, and California later required courts to review eligible records automatically. If you think a conviction of yours qualifies and it's still on your record, the court that handled the case can help.
Is anything changing in 2026?
No major changes to adult-use limits in 2026. California already restricts intoxicating hemp products sold outside licensed dispensaries, and the federal hemp changes below will tighten that further.
Federal law in 2026
Federal law still treats recreational cannabis as illegal. In April 2026, the federal government moved marijuana sold under a state medical license (and FDA-approved cannabis medicines) to Schedule III, but adult-use cannabis is still Schedule I. That means it's still banned on federal land and can't legally cross state lines, even between two legal states.
Separately, a federal ban on intoxicating hemp products takes effect in two steps: synthetic and converted cannabinoids like delta-8 lose their legal status on November 12, 2026, and naturally derived hemp THC (THCA flower, hemp delta-9 edibles and drinks) on December 11, 2026.
