Planning a trip outside California? Here's a clear, state-by-state breakdown of which U.S. states accept a California medical marijuana card, which require visitor registration, and which won't recognize your card at all — with links to the official .gov source for every state.
Reciprocity is when one state honors a medical cannabis card issued by another state. In practice, this can mean three different things depending on where you're traveling. Some states let you walk into a dispensary and purchase as a visiting patient. Others only allow you to possess medical cannabis you obtained legally elsewhere. A few have no formal program but allow recreational purchases for adults 21 and older. Cannabis still remains a Schedule I substance under federal law, so transporting cannabis across state lines is a federal offense regardless of the state laws on either side.
These states either recognize out-of-state cards directly or offer a quick visiting patient registration process. Always carry your card and a government ID.

The following states do not currently recognize a California medical marijuana card in any form. If you carry medical cannabis into these states, you are not protected by their medical program. Some of these states do have adult-use sales, which means adults 21 and older can still purchase recreationally with a government ID.
| State | Recreational Option for 21+? | Official Government Source |
|---|---|---|
| Florida | No (medical only, residents) | FL Dept. of Health OMMU |
| New York | Yes | NY Office of Cannabis Management |
| Texas | No | TX Compassionate Use Program |

California does not have a formal medical reciprocity program for visiting patients. However, because California has adult-use cannabis, any visitor aged 21 or older can purchase from a licensed recreational dispensary with a valid government ID, even without a medical marijuana card. For details, see the California Department of Cannabis Control.
Yes, but only certain states recognize an out-of-state card. Nevada, Hawaii, Maine, Michigan, Delaware, Washington D.C., New Mexico, Minnesota, Oklahoma, Arkansas, Arizona, Rhode Island, New Hampshire, Louisiana, and Utah have programs that recognize CA cards in some form. Always confirm with the state's official .gov source before traveling.
No. Cannabis remains a Schedule I controlled substance under U.S. federal law, and crossing state lines with cannabis is a federal offense regardless of the state laws involved. Even between two legal states, transporting cannabis across the border is illegal. Always purchase locally at a licensed dispensary in the state you are visiting.
A California physician's recommendation is valid for one year from the date of issue. The state-issued Medical Marijuana Identification Card (MMIC) issued through your county health department is also valid for one year. You can renew your card online when it expires.
Some states require advance registration, including Hawaii (apply 1-2 weeks before travel), Oklahoma (apply online before purchasing), Utah (21-day visitor card), and Washington D.C. (online non-resident card). Other states accept your California card on arrival. Always check the official state .gov page in advance.
No. Each state sets its own possession and purchase limits, and visiting patients are subject to the host state's rules, not California's. Some states cap purchases at lower amounts than California's 8-ounce possession limit, while others allow more for specific conditions. Check the host state's official cannabis or health agency before your trip.
