Understanding Marijuana Laws in California
April 20, 2026 | Nafiz M. Ahmed
California was one of the first states to legalize recreational marijuana, but that does not mean that anything goes. State law still imposes various restrictions on the plant, including how much you can possess and where you can use it. Crossing any of those lines can result in criminal charges that carry serious consequences for defendants.
If you are facing a marijuana-related charge in California, learning about how these laws work is an important first step, as is reaching out to an experienced drug crimes lawyer for a free consultation and legal advice.
What Is Legal Under California’s Marijuana Laws?
Under Proposition 64, which California voters approved in 2016, adults aged 21 and older are permitted to use marijuana recreationally. The law allows individuals to:
- Possess up to 28.5 grams of marijuana flower
- Possess up to 8 grams of concentrated cannabis
- Grow up to six plants at a private residence for personal use
- Purchase marijuana from a licensed dispensary
These allowances apply only to adults. Minors are not permitted to use marijuana under state law, though the penalties they face are generally less severe than those for adults.
When Marijuana Possession Becomes a Crime
Despite the fact that recreational use is legal, there are still several situations where possession can lead to criminal charges. Possessing more than the legal limit is one of the most common examples. For adults, possession of more than 28.5 grams of flower or more than 8 grams of concentrate can result in a misdemeanor charge.
Other conduct that remains illegal under California law includes:
- Possessing marijuana on school grounds
- Smoking marijuana in public places
- Driving under the influence of marijuana
- Possessing marijuana with the intent to sell without a license
Many of these activities are still illegal even for medical card users as well.
Penalties for Marijuana Offenses in California
The penalties for marijuana-related crimes in California vary based on the nature of the offense and the defendant’s criminal history, if applicable.
A misdemeanor marijuana offense can result in up to six months in county jail and a fine of up to $500. More serious offenses, such as selling marijuana without a license, can be charged as felonies. Felony convictions may carry state prison time along with significantly higher fines.
For minors caught with marijuana, the consequences are handled differently. Rather than jail time, juveniles typically face drug education and counseling programs and other rehabilitative measures. Repeat offenses, however, can lead to more serious outcomes.
Federal Law Still Prohibits Marijuana
One aspect of marijuana law that many people overlook is the conflict between state and federal law. While California permits recreational use, marijuana remains classified as a Schedule I controlled substance under the federal Controlled Substances Act. This means that possession and use are still technically illegal at the federal level.
In practice, federal enforcement against individuals who comply with state marijuana laws has been limited. However, this federal classification can sometimes create problems in certain areas of life, such as in seeking federal employment and firearm ownership. Federal law still may come into play in these circumstances, even if you’re adhering to state law.
