Medical Marijuana Card Laws Across the States

How the law of reciprocity affects medical marijuana cardholders traveling outside of their state

So, you’ve paid the fee and been approved, and now you’re the proud owner of your very own medical marijuana (MMJ) card in the state of Arizona. You can buy your medicine in the Grand Canyon State without hassle!

Now say you’re planning an out-of-state trip, and you (understandably) don’t want to go without your legal medicine. How and where will your card be accepted, and how much medical marijuana are you legally permitted to buy & keep on your person? We’ve been asking ourselves the same questions, so in order to make your travels easier, we compiled some information on the map below, identifying the states that have passed MMJ card reciprocity legislation. Happy trails!

Hint: Use command+f/control+f to search for your state quickly.


Arizona does not allow out of state card holders to buy marijuana from state-licensed dispensaries, but it does recognize out of state authorizations. You can smoke, you can’t buy.


There is currently no reciprocity, but there may be soon. The Arkansas Medical Marijuana Amendment lays out some guidelines as to how out of state patients can receive care, but because the Arkansas medical program is still in its early stages. There hasn’t been a developed reciprocity program yet.

District of Columbia

District of Columbia accepts medical marijuana cards from Colorado, Connecticut, Delaware, Florida, Hawaii, Illinois, Maine, Maryland, Massachusetts, Michigan, Montana, New Hampshire, New Jersey, Oregon, Rhode Island, and Washington. You must provide a valid State-issued ID and proof of medical marijuana certification. However, recreational use is legal in D.C.


Out of state patients can receive a medical card that applies for 60 days as long as the patient has a valid medical card from a U.S. State or territory, and a government-issued ID from the same state, and a qualifying condition in Hawaii. The application can be filled out up to 60 days in advance and takes about 10 minutes to complete. The application costs $49.50 and is valid for 60 consecutive days. Out of state, patients are only allowed to apply two times per the calendar year.

New Hampshire

Out of state, patients can legally possess medical marijuana that they enter the state with but cannot be served by dispensaries within the state.


Out of state, medical marijuana patients can apply for a temporary medical card that is only valid for 30 days and requires a $100 application fee. This card can be renewed, and an approval letter and medical card will be sent within 14 days if deemed complete and requirements met. Patients who are minors can receive temporary medical cards as well.


There is legislation that states there is no Medical card reciprocation, but there is a loophole that allows parents or legal guardians of patients under 18 to buy cannabis products. Although, this law is set to be repealed in the next two years.

Rhode Island

Rhode Island requires two forms of government ID, and you must be in a state database that tracks sales (Alaska, Arkansas, California, Colorado, Delaware, District of Columbia, Hawaii, Illinois, Maryland, Massachusetts, Michigan, Montana, New Mexico, North Dakota, New York, Nevada, Ohio, Oregon, Pennsylvania, Rhode Island, and Washington). Out of state, patients can carry up to 2.5 ounces every 15 days.

States that don’t offer reciprocation

The following states that have legalized medical marijuana have no legislation on Medical Card reciprocity: Utah, Montana, Florida, North Dakota, Minnesota, Illinois, Ohio, West Virginia, Maryland, New York, and Connecticut
