Which U.S. States Accept Out-of-State Medical Marijuana Authorizations?

As more and more states legalize medical marijuana, a lot of patients are starting to wonder if their authorizations are valid in any states other than where they were first issued. Fortunately, some medical marijuana-legal states do indeed accept out-of-state authorizations, and they’re listed below. The number of states is small right now, but we’ll continue to update it as more states start to allow out-of-state documentation.*

*Please note: Accepting an out-of-state medical marijuana authorization is entirely up the discretion of a dispensary owner, particularly in stricter states like Michigan and Rhode Island. We recommend calling in advance to ensure that they will allow you to purchase medicine.

Arizona

Technically, Arizona recognizes out-of-state medical marijuana authorizations but, unfortunately, doesn’t allow out-of-state patients to visit local state-licensed dispensaries. So long as you are a registered medical cannabis patient in your home state, you can still enjoy the beauty of the desert, picturesque sunsets, and one of the Seven Wonders of the Natural World – the Grand Canyon – without worrying about having your medicine confiscated.

Hawaii

Medical marijuana patients visiting the idyllic paradise will soon have the option of purchasing legal medical cannabis from dispensaries on every island in the chain. By January 1, 2018, the eight licensed dispensaries should be fully operational and you’ll be able to enjoy sitting on the beach with a joint or an edible, free of worry and soaking up the sun and the sights of Hawaii – volcanoes, sea turtles, pristine beaches, shaved ice and the most beautiful sunsets you’ve ever seen.

Hawaii’s Patient Possession Limits: 4 ounces every 15 consecutive days, or 8 ounces every 30 consecutive days.

Maine

Even if you’re not looking to star in a Stephen King novel, Maine is a gorgeous place with friendly, down-to-earth, accommodating locals. Whether you’re touring the famous lighthouse-abundant coastlines, watching whales leap from the Atlantic, or feasting on fresh lobster, Maine won’t let you down. Maine legalized cannabis in 2016, so whether or not you’ve got a patient registry card for your state, it is legal to possess and use cannabis, and retail sales are coming soon.

Maine’s Patient Possession Limits: 2 1/2 ounces for both visiting patients with a valid registry identification, as well as for adults with a valid government-issued identification.

Michigan

The Great Lake State contains more than 11,000 lakes and borders four of the Great Lakes. It’s also known for some of the best craft beers in the continental United States, so if you’re a beer and cannabis enthusiast, Michigan could provide you with the best of both worlds. Be careful as an out-of-towner, however. There are plenty of restrictions on the state’s medical marijuana laws that even law-abiding Michigan MMJ patients have faced harassment from law enforcement. You may be able to visit the dispensaries, but don’t flaunt your cannabis use or possession.

Nevada

Nevada’s legalization means that your medical marijuana card won’t be necessary for long, but as an out-of-state card-carrying medical cannabis patient, you’ll have the privilege of visiting dispensaries even before legal cannabis sales begin for tourists. There are even rumors that Nevada may begin licensing bars and restaurants to allow public cannabis consumption, as as bid to increase cannabis tourism. Can you imagine walking down the Las Vegas strip with a joint in hand?

Nevada’s Possession Limits: 2 1/2 ounces and/or a maximum allowable quantity of edible cannabis products and cannabis-infused products, or 1 ounce of cannabis flower for adult consumers.

New Hampshire

Just a little ways up the road from Rhode Island and a neighbor to Maine, New Hampshire is another New England haven that respects out-of-state medical cannabis recommendations. There are no operating dispensaries in the region yet, but you are legally allowed to possess cannabis for medicinal purposes in the state. One of the more mountainous terrains, New Hampshire is home to the tallest peak in the region, Mount Washington, which summits at more than 6,000 feet and is accessible via the Cog Railway, one of the first railways in the world. Sit back, relax, and watch the world expand as you climb higher and higher into the clouds.

New Hampshire’s Patient Possession Limits: 2 ounces; patients must be authorized for the same qualifying medical conditions that are allowed under New Hampshire’s medical marijuana law.

Pennsylvania

It’s always sunny in the City of Brotherly Love, but just in case it isn’t, the lawmakers have created a loophole for medical marijuana patients. It is legal for the parent or guardian of a minor under 18 years of age to lawfully obtain medical cannabis from another medical state to be administered to the minor. However, this part of the law will be repealed within 730 days (2 years) and only applies to underage patients.

Pennsylvania’s Patient Possession Limits:  Patients may possess pills, oils, topical creams, tinctures and dry leaf for vaporization only.

Rhode Island

Rhode Island, also known as the Ocean State, is home to some of the prettiest darn beaches you’ve ever seen. With 400 miles of coastline, nearly a quarter of the state is on the waterfront and contains 20 percent of America’s landmarks. Stop off in Providence with your authorization and you’re set for a primo beachside escapade. Take the ferry to Block Island and enjoy the beauty of a pristine beach vista with the feel of a quiet, small town – you’ll never want to leave!

Rhode Island’s Patient Possession Limits: 2 1/2 ounces of usable cannabis.
