What is Medical Marijuana Reciprocity?
MMJ reciprocity refers to laws that have been created to allow medical marijuana patients with valid medical marijuana cards to purchase, possess, and use medical marijuana in a different state. MMJ patients who are traveling to states that have a reciprocity program must carry along their current MMJ cards to prove that they are cannabis patients. With this card, they will be able to legally purchase cannabis from dispensaries in the state that they are visiting.
