In California, can I smoke or consume cannabis in public places?

No. The Adult Use of Marijuana Act (Prop. 64) prohibits smoking or consumption of medical and recreational cannabis in public places or in places where smoking tobacco is prohibited, which includes but is not limited to hallways and lobbies of apartment buildings and hotels, on the street, in schools, amusement parks, public parks and places of business usually open to the general public.

Additionally, consumption or smoking of cannabis is prohibited within 1,000 feet of a school or youth area while children are present, except on private residential property provided smoking is not detectable by children

A person with a valid physician's recommendation can smoke where public smoking of cigarettes, cigars, etc...is allowed. However, there are FIVE places where a person with a valid physician's recommendation CANNOT SMOKE: • 1. No smoking zone. • 2. Within 1000 feet from a school or youth facility (unless in a private residence). • 3. In a motor vehicle that is operating. • 4. While operating a boat. • 5. On a school bus.
