California has had legal recreational marijuana for adults since 2018, but the rules are more detailed than most people realize. You can still be arrested for possession in the wrong place, for the wrong amount, or under the wrong circumstances. And federal law, which was rewritten in April 2026 with the partial rescheduling of marijuana, still treats most cannabis activity as a controlled substance.
This guide breaks down what is and isn’t legal under California recreational marijuana laws in 2026: possession limits, where you can consume, cultivation rules, the marijuana DUI standard, criminal penalties for what’s still illegal, and how the federal rescheduling affects everyday users.
If you’ve been arrested or charged with a marijuana-related offense, talk to the Los Angeles drug crime attorneys at Manshoory Law Group before your first court date.
What Proposition 64 Legalized
California voters passed Proposition 64 in November 2016. Legal recreational sales began on January 1, 2018. Under Prop 64, adults 21 and older can:
- Possess up to 28.5 grams (about 1 ounce) of cannabis flower
- Possess up to 8 grams of concentrated cannabis (hash, oil, wax, extracts)
- Cultivate up to 6 plants per residence for personal use (not per person)
- Purchase cannabis from state-licensed retailers
- Give away up to 28.5 grams to another adult 21 or older, as long as no money changes hands
This is the core legal framework. Everything else is built on top of it, and the limits matter. Possessing 29 grams is not the same as possessing 28.5 grams under California law, and once you cross the threshold, criminal penalties attach.
Where You Can and Can’t Use Cannabis
Legal possession does not mean legal use anywhere. California law restricts where you can consume cannabis even if you’re within the possession limits:
Where consumption is legal:
- On private property, with the owner’s permission
- Inside a licensed cannabis consumption lounge (legal statewide since January 2025 under AB 1775)
Where consumption is illegal:
- Any public place, including streets, sidewalks, parks, and businesses
- Anywhere smoking tobacco is prohibited
- Within 1,000 feet of a school, day care, or youth center while children are present
- In a vehicle, whether moving or parked (Vehicle Code §§ 23220, 23221)
- On federal property of any kind, including national parks, federal buildings, and airports
Violations of public-use rules are typically infractions punishable by fines starting around $100, but penalties escalate quickly near schools and for combined offenses.
Cannabis and Driving: The Marijuana DUI
You can be charged with DUI for driving under the influence of marijuana under Vehicle Code § 23152(f). Unlike alcohol, California has no specific THC blood-level threshold. Prosecutors must prove actual impairment, usually relying on:
- Officer observations (driving pattern, speech, coordination)
- Field sobriety tests
- Drug Recognition Expert (DRE) evaluations
- Blood tests showing the presence of THC or its metabolites
A marijuana DUI conviction carries the same penalties as an alcohol DUI: fines, license suspension, mandatory drug education, probation, and possible jail time. You can also be charged with an open-container offense (VC § 23222(b)) for having an open package of cannabis in a vehicle, even if you’re not impaired.
This is one of the most common ways adults who follow possession rules still end up in criminal court. Keep cannabis sealed and in the trunk when traveling.
Cultivation Rules
Adults 21+ can grow up to 6 plants per residence (not per person). Local governments can:
- Require indoor cultivation
- Reasonably regulate where and how plants are grown
- Ban outdoor cultivation outright
Growing more than 6 plants without a state license can be charged as a misdemeanor under Health & Safety Code § 11358, with penalties up to 6 months in county jail and a $500 fine. Repeat offenses, environmental violations, and large-scale cultivation can be charged as felonies. For a complete breakdown, see our guide to cannabis cultivation laws in California.
What’s Still a Crime Under California Law
Plenty of marijuana-related conduct remains criminal in California:
Possession over the legal limit (HS § 11357)
- More than 28.5g flower or 8g concentrate: misdemeanor, up to 6 months jail and $500 fine
- Possession by anyone under 21: infraction with drug education and community service
Possession with intent to sell (HS § 11359)
- Misdemeanor for most adults under Prop 64, up to 6 months jail and $500 fine
- Felony for repeat offenders, those with prior serious convictions, or those using minors in the operation
Unlicensed sale or transport (HS § 11360)
- Misdemeanor in most cases
- Felony when minors are involved, large amounts cross state lines, or other aggravating factors apply
Sales to minors (HS § 11361)
- Felony, with significantly enhanced penalties when the buyer is under 14
Possession on K-12 school grounds
- Misdemeanor or infraction depending on age
The takeaway: legalization isn’t a free pass. Most enforcement now focuses on unlicensed commercial activity, sales involving minors, and over-the-limit personal possession, but those charges are real and can be serious.
Federal Marijuana Law: The 2026 Update
This is the area that has changed most dramatically since the original 2017 version of this article was published. For decades, marijuana sat in Schedule I of the federal Controlled Substances Act, alongside heroin, classified as having no accepted medical use and a high potential for abuse.
That changed in April 2026.
Following President Trump’s December 18, 2025 executive order, the DOJ and DEA issued a final order on April 23, 2026 that moved two categories of marijuana from Schedule I to Schedule III:
- FDA-approved drug products containing marijuana
- Marijuana subject to a qualifying state medical marijuana license
A separate DEA administrative hearing on broader rescheduling of all marijuana, including recreational cannabis, began June 29, 2026. As of this writing, that broader process is still underway.
What this means for the average California user:
- State-licensed recreational marijuana sold to adults 21+ in California is still a Schedule I controlled substance under federal law until the broader rescheduling is completed.
- In practice, federal prosecutors continue to focus on large-scale trafficking, interstate distribution, sales involving minors, and operations that violate state law. They generally do not target small-scale personal use by adults in legal states.
- Marijuana remains illegal on all federal property, including national parks and airports, regardless of state legalization or rescheduling.
- Crossing any state line with cannabis (even to another legal state) remains a federal offense.
If you fly with cannabis, take it onto federal land, or are involved in any commercial activity outside California’s licensing system, federal law can still reach you.
Employment Protections Under AB 2188
Effective January 1, 2024, AB 2188 prohibits California employers from discriminating against employees and applicants for off-duty cannabis use away from the workplace. Employers can still:
- Prohibit cannabis use on the job or while working
- Test for current impairment (active THC), but not for non-psychoactive metabolites that linger for weeks
- Maintain drug-free workplace policies that prohibit use during work hours
The law has carve-outs for federal-contractor employers, certain construction jobs, and a few safety-sensitive positions. If you’ve been fired or denied a job over a positive cannabis test based on metabolites, talk to a lawyer.
What to Do If You’re Arrested for a Marijuana Offense
If you’re stopped, detained, or arrested for anything cannabis-related in California:
- Stay calm and polite. Don’t argue or resist.
- Don’t consent to searches. If asked, say clearly: “I do not consent to a search.”
- Invoke your rights. “I am invoking my right to remain silent. I want a lawyer.”
- Don’t try to explain. Officers are not the right audience. Save your account for your attorney.
- Call a criminal defense attorney immediately. Especially before any interview, charging decision, or arraignment.
Most California marijuana cases turn on the legality of the stop and the search. A motion to suppress under Penal Code § 1538.5 can sometimes end the case before it ever reaches trial.
Frequently Asked Questions
How much marijuana can I legally possess in California?
Adults 21 and older can possess up to 28.5 grams (about one ounce) of cannabis flower and up to 8 grams of concentrated cannabis (such as hash, wax, or oil). Possession over those limits is a misdemeanor under Health & Safety Code § 11357.
Can I grow my own marijuana in California?
Yes. Adults 21 and older can cultivate up to 6 plants per residence (not per person) for personal use. Local governments can require indoor cultivation and reasonably regulate how it’s done, but they cannot ban the 6-plant personal grow.
Is marijuana still illegal under federal law?
Partially. As of April 23, 2026, FDA-approved marijuana drug products and state-licensed medical marijuana are now Schedule III substances. All other marijuana, including California’s recreational adult-use market, remains Schedule I federally pending the outcome of the DEA’s broader rescheduling hearing, which began June 29, 2026.
Can I be fired for using marijuana in California?
Not for off-duty use, in most cases. Effective January 1, 2024, AB 2188 prohibits employers from discriminating against employees for using cannabis away from work. Employers can still prohibit on-the-job use and test for active impairment, but they generally can’t fire you for non-psychoactive metabolites in your system.
Can I drive with marijuana in my car in California?
Yes, but only if it’s sealed in its original packaging or in the trunk. Driving with an open container of cannabis is a violation of Vehicle Code § 23222(b). Driving while impaired by marijuana is a DUI under Vehicle Code § 23152(f), with the same penalties as an alcohol DUI.
Can I fly with marijuana within California?
No, even for in-state flights. Airports are federal property, and the TSA operates under federal law. While TSA’s stated policy is that finding small amounts of cannabis is not a priority, you can still be referred to law enforcement and face federal consequences.
What if I’m caught with more than the legal amount?
Possession over the legal limit is typically a misdemeanor under Health & Safety Code § 11357, punishable by up to 6 months in county jail and a $500 fine. Possession with intent to sell is a separate charge under § 11359, with the same baseline penalty but the potential for felony enhancement.
Will old marijuana convictions be cleared from my record?
Possibly. Prop 64 created a process for reducing or dismissing many prior marijuana convictions that would no longer be crimes under current law. The Department of Justice and county DAs have proactively reviewed thousands of cases for resentencing. If you have an old conviction that’s still on your record, an attorney can help you petition for relief.
Can minors be charged for marijuana possession?
Yes. Anyone under 21 caught with cannabis can be cited for an infraction. The penalty is typically drug education classes and community service, with no jail time for first offenses, but the citation does become part of the juvenile or criminal record.
