Is It Illegal to Be High on Marijuana in Public in California? 

August 19, 2026 | Nafiz M. Ahmed

California legalized recreational marijuana for adults 21 and older through Proposition 64. Since then, many residents have assumed that anything related to marijuana use is fair game. However, the law draws a clear line between what you can do in private and what is allowed in public.

While simply feeling the effects of marijuana in a public space is not automatically a crime, certain kinds of circumstances can cross into criminal territory. Determining where that line falls is essential for anyone who uses cannabis in California.

Public Marijuana Consumption Laws in California

Although recreational marijuana is legal to possess and use in California, the state restricts where you can actually consume it. Smoking, vaping, and eating cannabis products is only permitted on private property with the owner’s consent.

Public consumption is prohibited in locations such as:

• Sidewalks
• Streets
• Restaurants
• Retail stores
• Anywhere tobacco smoking is banned
• Within 1,000 feet of a school while children are present
• Inside any motor vehicle

Getting caught consuming marijuana in a public space can result in a fine. This applies regardless of the amount you have on you, as long as you are actively using it in a restricted area.

When Could Being High in Public Become a Crime?

This is where the distinction becomes important. Simply being under the influence of marijuana while out in public is not, on its own, a criminal offense. California does not punish people solely for feeling the effects of cannabis while walking down the street or sitting in a park.

However, Penal Code 647(f) changes the picture when impairment reaches a certain level. 

Under this statute, it is illegal to be under the influence of any drug in a public place if your level of intoxication meets one of two conditions:

• You are so impaired that you can no longer take care of your own safety or the safety of those around you
• Your condition blocks or interferes with the free use of a public walkway or roadway

You can also be charged with driving under the influence of marijuana if you’re pulled over while high on the substance, marking another circumstance where being high in public could constitute a crime.

What Penalties Could I Face for Marijuana-Related Crimes?

Public intoxication under Penal Code 647(f) is a misdemeanor. 

First-time offenders typically receive probation or community service, but the maximum penalties include:

• Up to six months in county jail
• A fine of up to $1,000
• A mandatory minimum of 90 days in jail if convicted three times within 12 months

The stakes rise sharply if you drive while high; a first offense can result in:

• Up to six months in jail
• Fines exceeding $3,000 after penalty assessments
• A six-month driver’s license suspension
• Mandatory DUI education classes

These charges are also priorable, meaning repeat offenses within 10 years carry increasingly harsh consequences.
