Guide to Medical Marijuana Reciprocity Laws in the United States - July 28, 2021

One of the most frequently asked questions by MMJ patients is-

Will my medical marijuana card be accepted in other states?

Well, the answer to this question will depend on the reciprocity laws of the state you are traveling to. And it’s not necessary that all US states with legal medical marijuana follow reciprocity. For instance, cannabis is legal in New York but it does not offer reciprocity.

So, you need to understand the laws before crossing state borders. This guide can help you understand everything about medical marijuana reciprocity in the US.

What is Medical Marijuana Reciprocity?

Medical marijuana reciprocity simply refers to certain laws that are laid out to provide legal protection to non-resident MMJ patients and allow them to possess and purchase medical cannabis in a different state. Most states with established medical marijuana programs also have a proper reciprocity program that recognizes out-of-state recommendations or MMJ cards within their boundaries.

But, medical marijuana reciprocity is not as simple as it seems.

First, reciprocity primarily includes two aspects: possession and purchase. Some states follow complete reciprocity and allow both, while others follow partial reciprocity and only allow possession of medical cannabis.

Medical Marijuana Laws

Secondly, each state has its own reciprocity standards and criteria. So, the definition of reciprocity often changes in different states. For instance, while most states follow full reciprocity and recognize out-of-state MMJ cards for possessing and purchasing cannabis in their dispensaries, others recognize out-of-state MMJ cards as a document that can be used to apply for a state-issued temporary card.

So, if you are a medical marijuana patient and traveling to a different state, this guide of medical marijuana reciprocity laws in the US will come in handy for you.
