Medical Card Reciprocity: Which States Honor Out-of-State Patients in 2026
Only a handful of states honor out-of-state medical marijuana cards — and each has its own requirements, time limits, and registration steps. This guide covers every reciprocity arrangement currently in place.
Most states that have medical cannabis programs do not honor out-of-state patient cards. Only a small handful extend legal protections to visiting patients — and those that do impose varying conditions, registration requirements, and time limits.
States That Currently Honor Out-of-State Medical Cards
Arizona
Arizona allows qualifying patients from other states to purchase and possess cannabis with a valid out-of-state medical card. Patients may possess up to 2.5 ounces.
Arkansas
Arkansas recognizes out-of-state medical cannabis cards under its reciprocity provision. Possession limits follow Arkansas rules (3 ounces).
Hawaii
Hawaii has a 329D registry card process. Out-of-state patients must apply for a temporary registration card before arriving — the process takes several days and has a fee.
Missouri
Missouri allows visiting patients to apply for a 30-day temporary patient license with same-day approval common.
Oklahoma
Oklahoma offers a 30-day temporary medical license for $100 with same-day issuance. One of the most accessible visitor programs.

Rhode Island recognizes out-of-state medical cards for visiting patients for up to 6 months.
Utah
Utah allows reciprocity for visiting patients for up to 30 days for qualifying conditions.
What to Bring as a Visiting Patient
