NO, it doesn't necessarily have to be a CA ID/license. It can be any state ID/license or a valid passport, and the doctor's recommendation is only needed if you are under 21/medical marijuana patient
Yes you do need to have CA license or ID and if you have a doctor's rec it would help on the taxs but you not need one to go in.
All you need is a California ID. If you are under 21 years of age . then you need a doctors recommendation.
