Patients residing in the state of California can be evaluated for treatment with medical cannabis. This does not require a California state ID; however, it does require that the individual is in California at the time of evaluation. Medical cannabis dispensaries require a valid form of ID and a valid medical cannabis recommendation from California in order to permit entry. In some cases, a dispensary may require documents verifying California residence (such as a lease agreement or utility bill) if you show an out of state ID. Delivery services tend to accept any valid ID and are your best bet if you are concerned about having an out of state ID.
