California Proposition 64 and San Bernardino County rules ban smoking, vaping, or eating cannabis in public places, including streets, parks, and county buildings in unincorporated areas.
California Health and Safety Code section 11362.3 makes it unlawful to smoke or ingest cannabis in any public place or in a location where tobacco smoking is prohibited. San Bernardino County extends those rules across unincorporated regional parks, trails, and government facilities. Driving with an open cannabis container or consuming inside a vehicle remains illegal under California Vehicle Code section 23222. The county also prohibits commercial cannabis events outside of permitted state-licensed venues, and smoking near schools or daycares is a strict-liability offense.
Public cannabis use carries infraction fines that escalate near schools, plus possible misdemeanor charges for driving while consuming.
