You cannot smoke weed in public in California. Even though adults 21 and older can legally buy and possess cannabis, consuming it in any public place is an infraction that carries a $100 fine, and the fine climbs to $250 near schools. The only legal commercial setting for on-site consumption is a licensed cannabis lounge in a city that permits them.
What Counts as a Public Place
The ban is broad. California law prohibits smoking, vaping, or eating cannabis on sidewalks, in parks, on beaches, in plazas, in parking lots, and in any business open to the public.1California Legislative Information. California Health and Safety Code 11362.3
Smoking and vaping cannabis are also banned everywhere tobacco smoking is banned. That pulls in offices, restaurants, bars, hotels, public transit, government buildings, and workplaces. The tobacco-linked ban technically covers only smoke and vapor, not edibles, but the general public-place rule catches edibles separately. The practical result is the same in all of those spaces: no consumption in any form.1California Legislative Information. California Health and Safety Code 11362.3
Bars and restaurants with liquor licenses get special treatment. The California Department of Alcoholic Beverage Control has stated that these venues count as public places for cannabis purposes even when the bar is closed, operating after hours, or holding a suspended license.2Alcoholic Beverage Control.

The 1,000-Foot Zone Around Schools
Smoking cannabis within 1,000 feet of a school, day care center, or youth center while children are present is a higher-penalty violation. The rule reaches unusually far: you can smoke in a private residence inside that zone only if the smoke is not detectable by anyone on the school grounds. If people at the school can smell it, you’re in violation even inside your own home.1California Legislative Information. California Health and Safety Code 11362.3
The “detectable” standard is subjective. A neighbor or school employee reporting the smell can be enough to support a citation with the enhanced fine.
Cannabis in Your Car
Having an open container or open package of cannabis while driving or riding in a motor vehicle, boat, or aircraft is a separate infraction. It applies to drivers and passengers alike.1California Legislative Information. California Health and Safety Code 11362.3
The California Supreme Court clarified the standard in Sellers v. Superior Court (2026). The statute contains no sealing requirement. A violation instead requires cannabis in a usable quantity, in an imminently usable condition, and readily accessible to an occupant. Loose shake on the floor or a trace amount that can’t realistically be used wouldn’t qualify. An open jar of flower in the cupholder would.
The cleanest approach is to keep cannabis in its original sealed dispensary packaging and store it in the trunk or a locked glove box. That takes accessibility off the table.
Federal Land and Flying
Cannabis remains illegal under federal law, and public spaces controlled by the federal government are governed by that law rather than California’s. National parks, national forests, military bases, VA hospitals, federal courthouses, and post offices are all federal property. Possession or use there is a criminal offense. A first offense can bring up to a year in prison and a minimum $1,000 fine.3U.S. Department of Agriculture Forest Service. Cannabis Use on National Forest System Lands
Air travel is another exposure point. TSA officers don’t actively search for cannabis, but if they find it during screening, they must refer you to law enforcement. Some California airport police may ask you to dispose of it, but that outcome isn’t guaranteed. Flying with cannabis across state lines is a federal offense regardless of whether both states have legalized it.4U.S. Department of Transportation. DOT’s Notice on Testing for Marijuana
Smoking Where You Live
Your home is not automatically a safe place to smoke. Under California Civil Code section 1947.5, a landlord can prohibit smoking in dwelling units, common areas, and outdoor spaces through the lease. A no-smoking lease covers cannabis smoking and vaping, not just tobacco.5California Legislative Information. California Civil Code 1947.5
This particular statute reaches only smoking and vaping. Edibles, tinctures, and other non-smoked forms aren’t automatically covered, though a landlord could restrict them through other lease terms.
Federally subsidized housing is stricter. HUD prohibits admitting cannabis users to any HUD-assisted program, including Section 8 vouchers and public housing. The rule applies to medical cannabis patients with a valid California recommendation, and use in federally subsidized housing can be grounds for eviction.6HUD Exchange.

Where You Can Legally Consume in Public
Licensed consumption lounges and authorized cannabis events are the exception. State law allows local jurisdictions to authorize on-site consumption at licensed retailers or microbusinesses, but only where the city or county has opted in.7California Legislative Information. California Business and Professions Code 26200
Cities currently permitting consumption lounges include San Francisco, Oakland, West Hollywood, and Palm Springs, along with a handful of others. Inside a lounge, everything consumed must be bought on-site, no outside cannabis is allowed, consumption cannot be visible from public property, and alcohol is completely banned.2Alcoholic Beverage Control. Cannabis and Alcoholic Beverages
As of January 1, 2025, Assembly Bill 1775 lets lounges in jurisdictions that allow it serve food prepared on-site and nonalcoholic beverages. Previously they could only sell prepackaged snacks.
What the Fine Actually Costs
Public cannabis consumption is an infraction, not a misdemeanor or felony. The base fine is $100. Within 1,000 feet of a school, day care center, or youth center while children are present, the fine goes up to $250.8California Legislative Information. California Health and Safety Code 11362-4
An infraction is closer to a traffic ticket than a criminal charge. No jail, no criminal record. But California courts typically add surcharges and assessment fees on top of the base fine, so the amount you actually pay at the window will be higher, sometimes by several multiples of the base.
The penalty picture changes entirely on federal land. Cannabis possession in a national park or forest carries a mandatory court appearance before a federal magistrate, with potential imprisonment of up to one year and a minimum $1,000 fine for a first offense.3U.S. Department of Agriculture Forest Service.
