Reciprocity

Washington is located in the Pacific Northwest, and many residents travel frequently to neighboring and nearby states. As a result, Washington medical cannabis recognition cardholders often wonder whether other states recognize their medical authorization and what that means for legal access to cannabis while traveling.

On this page, we’ll explain how medical cannabis reciprocity works for Washington patients, including whether other states honor Washington medical cannabis recognition cards and what limitations may apply when seeking access outside Washington.

Understanding Reciprocity for Medical Marijuana Patients

To begin, it helps to understand what “reciprocity” means in the context of medical cannabis. Reciprocity refers to one state recognizing another state’s medical cannabis card, allowing a visiting patient to legally possess or, in some cases, purchase medical cannabis under that state’s program.

Washington does not participate in medical cannabis reciprocity. Out-of-state patients cannot use their medical cannabis cards to register in Washington’s medical authorization database. However, adults age 21 and older may legally purchase cannabis from licensed retail stores under Washington’s adult-use laws.

That said, some other states may offer limited or full reciprocity to Washington medical cannabis recognition cardholders. The rules vary by jurisdiction and may include requirements such as applying for a temporary visitor card, qualifying under specific medical conditions, or being limited to possession without purchasing privileges.

States Recognizing Washington Medical Marijuana Cards in 2026

Several states allow some level of access to medical cannabis for patients traveling with a valid Washington medical cannabis recognition card. While Washington does not accept out-of-state cards for its medical program, Washington cardholders may be able to possess or purchase medical cannabis in other states depending on local program rules.

In some cases, states offer full dispensary access to visiting patients. Others require Washington patients to apply for a temporary visitor registration, limit access to possession only, or restrict eligibility based on qualifying conditions. Because cannabis laws differ widely and are subject to change, Washington patients should always verify requirements directly with the destination state’s medical cannabis program before traveling.

States that may recognize Washington medical cannabis cards, either fully or with specific conditions, include:

• Arkansas (visitor card required)
• Hawaii (visitor card required; condition-based)
• Maine
• Michigan
• Nevada
• New Mexico
• Oklahoma (visitor card required)
• Utah (visitor card required; condition-based)
• District of Columbia (D.C.)

 

Since medical cannabis laws can change, patients planning to travel should confirm current reciprocity policies and requirements with the appropriate state agency before departure.
