Can you smoke weed on the beach or in a park in San Diego?
No. California bans using cannabis in public, and San Diego bans smoking and vaping, cannabis included, on city beaches, parks, boardwalks and piers. Federal land like Cabrillo is off-limits entirely. Legal use means private property.

The short version
- California Health and Safety Code §11362.3 bans smoking or ingesting cannabis in any public place, and smoking it anywhere tobacco is banned.
- San Diego's municipal code bans smoking, vaping and ingesting cannabis in any public place, and bans smoking and vaping on city beaches, parks, boardwalks and piers.
- State fines run up to $100 for public use and up to $250 where tobacco is banned, before penalty assessments.
- Cannabis remains federally illegal, so Cabrillo National Monument and military bases are off-limits.
- Adults 21+ can possess up to 28.5 grams of flower and 8 grams of concentrate; the county's only consumption lounge is in National City.
Recreational cannabis has been legal in California since 2018, which leads plenty of visitors to assume a joint at sunset on the sand is fine. It isn't. Legal to buy and legal to use in public are two different things, and San Diego's beaches are about as public as it gets.

What it costs if you're cited
Under state law, using cannabis in a public place is an infraction with a fine of up to $100. Smoking it where tobacco is banned, such as a beach or park, or near a school while kids are present, is up to $250. Court penalty assessments push the real bill higher. San Diego's own smoking rules carry a separate $10–$100 fine.
- Age: 21 and older.
- Possession: up to 28.5 grams of flower and 8 grams of concentrate; up to six plants at home.
- Driving: an open package in the passenger area is an infraction; keep it sealed or in the trunk.
- Related: alcohol is banned on city beaches too. See drinking on San Diego beaches.
