Any patient with a valid registry card may legally use marijuana for medicinal purposes and their caregiver may assist them in doing so. You can possess paraphernalia associated with growing or consuming marijuana for medical use. All patients must enroll in the state patient registry and possess a valid identification card in order to be legally protected. A copy of a registry identification card is not valid. A damaged card is not valid.
Between you and your caregiver, you can legally possess six marijuana plants, only three of which may be mature enough to bear usable marijuana, plus one ounce of marijuana in usable form. If you violate these limits, they can keep you off the registry for one year.
