Hey there, We can not supply medical cannabis to people from other states through a dispensary. Their cards are respected in Rhode Island so if you come from cali and you have medicine on you and your card you are protected by RI state law. But because you are not part of the RI medical cannabis program you can not add me(the Dispensary) as a caregiver. Also our RIcards will not protect us from other states that have or do not have medical cannabis programs.
