California citizens demanded, marched, protested for years, but they achieved their goal. You can now legally smoke your pot. But there are restrictions as to where, when, how much, with whom.

Health and Safety Code 11362.3. (If Smoking Cigarettes Is Prohibited, So Is Pot:) Wherever smoking tobacco is prohibited, you cannot smoke your marijuana. Prohibition against smoking includes using vape devices. You cannot smoke within 1000 feet of facilities that serve children. You cannot possess or smoke on grounds of school, day care center, or youth center while children are present. You cannot have an open container of marijuana while driving, or riding in vehicle, boat, aircraft. Carry your cannabis in your trunk, not your purses.

Medical marijuana continues to be lawful and guided by the Compassionate Use Act of 1996.
