Which US States Allow Out of State Patients to Buy Marijuana?

The number of states that will authorize patients from out-of-state medical marijuana programs is still relatively small. Many places will either permit patients access to dispensaries and/or permit medical cannabis possession within a reasonable amount. Cannabis laws are constantly changing across the country, and it’s refreshing to see that the list of cannabis-friently states is steadily growing! Let’s take a look at which US states offer reciprocity for guests that are cannabis patients.



Since Alaska legalized cannabis for recreational use, patients from other states do not need to undergo any special processes to obtain their medicine. All adults 21 years old and up can purchase and possess up to 1oz of cannabis at any licensed dispensary .


Visiting MMJ patients that come to Arizona are allowed to bring and use their own medicine, however, they are not permitted to purchase cannabis at any of Arizona’s dispensaries. The possession limits are of 2 ½ ounces of usable cannabis.


As long as patients fill out a visiting patient application and go through the process, they are good to go from a legal standpoint! Please note that if you purchase cannabis from any dispensary in Arkansas, it is heavily advised that you do not cross state lines with it otherwise you risk getting into legal trouble.


With the passage of Proposition 64, recreational and medical cannabis is now available for anyone with 21 or older and a valid government-issued identification. The possession limits are of 28.5 grams of cannabis flower and 5 grams of cannabis concentrate.


Just like in California, tourists are allowed to buy cannabis if they have valid government-issued identification, and are 21 or older. The possession limits are one ounce for non-resident adults.

Washington D.C. only allows reciprocity from certain states that have an equally functioning medical marijuana program. These states include:

  • Colorado
  • Connecticut
  • Delaware
  • Florida
  • Hawaii
  • Illinois
  • Maine
  • Maryland
  • Massachusetts
  • Michigan
  • Montana
  • New Hampshire
  • New Jersey
  • North Dakota
  • Ohio
  • Oregon
  • Pennsylvania
  • Rhode Island
  • Washington

While cannabis is decriminilized and is legal for recreational use, only authorized MMJ patients are able to purchase from dispensaries. Current laws prohibit the retail sale of cannabis in D.C. If your state is not on the aforementioned list, you can still bring your medicine as long as you keep a minimum on your person. You can legally possess up to 2 ounces of cannabis flower for personal use while concentrates and hashish remain illegal. If you visit D.C. make absolute sure you avoid consuming cannabis on federal land and stick to using on only on private property.

Michigan just recently legalized recreational use! Adults that are at least 21 years old are legally permitted to possess up to 2 ½ ounces of cannabis flower or 15 grams of concentrates. Dispensaries for medical marijuana are accessible throughout the state, however, solid legislation for retail sales is still in development so commercial purchase is currently unavailable.

The patient must also have the same qualifying medical conditions that are listed in New Hampshire’s medical marijuana program.

Rhode Island

As long as patients bring their physical medical marijuana card with a government-issued ID card from the same state, visiting patients can have access to dispensaries in Rhode Island. Out-of-state patients are also permitted to possess the same amount of medical marijuana as in-state patients. The possession limits are 2 ½ ounces of usable cannabis.
