Does Maryland recognize out-of-state medical cards?

No. Maryland does not have medical-card reciprocity. Out-of-state medical cards have no legal standing in Maryland. The Maryland Cannabis Administration only registers Maryland residents.

Can I buy cannabis in Maryland if I am visiting from out of state?

Yes, if you are 21 or older. Maryland legalized adult-use cannabis in July 2023, so visiting adults 21+ can purchase at any of Maryland's 103+ dispensaries with a valid government-issued ID. You pay the 12% recreational tax and are limited to 1.5 oz of flower, 12g of concentrate, or 750mg of THC edibles per transaction.

What if I am 18 to 20 with an out-of-state medical card?

Maryland does not honor out-of-state cards, and recreational sales are restricted to age 21 and over. There is no legal Maryland pathway for visiting patients aged 18 to 20. Options are to establish Maryland residency and apply for the free Maryland medical card, return home for your own state's purchases, or wait until age 21.

Can I bring cannabis purchased in Maryland back to my home state?

No. Cannabis remains federally illegal, and crossing any state line with cannabis is a federal crime regardless of card status. Buy in Maryland, consume in Maryland, and do not transport across state lines.

Do out-of-state visitors get the 12% tax exemption?

No. The 12% excise-tax exemption is only for Maryland-registered medical patients. Out-of-state visitors and unregistered Maryland residents pay the full 12% (rising to 15% by 2030).

How does Maryland reciprocity compare to other states?

Maryland has no reciprocity at all. Nevada honors out-of-state cards automatically. Arkansas issues a 30-day visiting-patient card for $50. Maryland's approach is closer to most adult-use states where the out-of-state medical card has no medical effect but adult-use purchase is open to anyone 21+.

What if I move to Maryland from another state?

Update your ID with the Maryland Motor Vehicle Administration, then apply for the free Maryland medical cannabis card through the MCA portal at cannabis.maryland.gov. Maryland's catch-all qualifying-condition provision is one of the most flexible in the country.

How Maryland Handles Out-of-State Cards

Unlike Nevada (full reciprocity) or Arkansas (visiting-patient card), Maryland offers no medical-card reciprocity. An out-of-state medical card has no legal standing in Maryland. There is also no visiting-patient registration program. The Maryland Cannabis Administration (MCA) only registers Maryland residents.

However, Maryland has been an adult-use state since July 1, 2023, so visiting patients who are 21 or older can still buy cannabis at any of Maryland’s 103+ licensed dispensaries — just without the medical-card benefits.

What Out-of-State Patients Can Do

Age 21 and Over

You can purchase as a recreational customer at any Maryland dispensary. Bring a valid government-issued photo ID (driver’s license, state ID, or passport). You will pay the 12% excise tax (rising to 15% by 2030) and standard sales tax. Recreational possession limits apply:

1.5 ounces of flower (or equivalent)
12 grams of concentrate
750 mg of THC in edibles

Ages 18–20

This is the structurally difficult group. Out-of-state cards do not work in Maryland, and recreational sales are restricted to age 21+. Visiting patients aged 18 to 20 cannot legally purchase from Maryland dispensaries even with a valid card from their home state. Cross-border options for ages 18 to 20:

DC residents: DC’s "gifting market" under Initiative 71 has no age limit at 21 + recreational, but the DC medical program does serve 18-20-year-olds with their own card. Out-of-state cards are not honored at DC dispensaries.
Pennsylvania residents: PA medical program (which serves 18+) is honored only within Pennsylvania. The card does not work in Maryland.
Virginia residents: Same posture — VA cards do not work in Maryland.
Delaware residents: Delaware medical program does not have reciprocity into Maryland.
Establishing Maryland residency: Move to Maryland, get an MVA-issued ID, and apply for the free Maryland medical card.

The Maryland Cannabis Administration registers only Maryland residents. Out-of-state medical cards have no legal effect in Maryland.

What Out-of-State Patients Cannot Do

Use an out-of-state card for the 12% tax exemption. The exemption is only for Maryland-registered patients.
Buy at Maryland medical purchase limits. Recreational limits apply unless you are MCA-registered.
Access medical-only delivery. Maryland medical delivery requires an MCA-issued patient ID.
Buy as a 18-20-year-old. No legal pathway; the only Maryland-legal options are to relocate, qualify under the Maryland program, or wait until age 21.
Possess more than recreational limits. 1.5 oz flower / 12g concentrate / 750mg THC edibles is the legal cap for non-Maryland-registered adults.

What Reciprocity Does Not Cover Anywhere

No transport across state lines. Cannabis remains federally illegal, and crossing any state border — even between two legal-cannabis states — is a federal crime regardless of card status.
No federal-land carve-out. Andrews AFB, Aberdeen Proving Ground, Patuxent River NAS, Goddard Space Flight Center, all national parks (Assateague, Catoctin, Antietam, etc.), and BWI Airport remain federal jurisdiction. Cannabis possession on federal land is a federal misdemeanor or felony.
No DUI defense. Maryland DUI law applies to all drivers regardless of card status; see consumption & driving.
No employment protections. Maryland employers may still drug-test and act on positive results.

Cross-Border Dynamics

Maryland sits at the geographic center of the Mid-Atlantic and shares borders with DC, Virginia, Pennsylvania, Delaware, and West Virginia. The cross-border dynamics matter to patients:

DC residents can drive 15 minutes into Montgomery or Prince George’s County for legal Maryland recreational purchases.
Virginia residents drive across the Potomac for Maryland purchases — Virginia has no operational adult-use retail.
Pennsylvania residents with medical cards must still use Pennsylvania dispensaries because Maryland does not honor PA cards.
Delaware launched adult-use in 2025; some northeast Maryland patients shop near the Delaware border.

See the Mid-Atlantic Hub for full cross-border dynamics.

If You Become a Maryland Resident

Move to Maryland, update your MVA-issued ID, and apply for the free Maryland medical cannabis card through the MCA portal. See how to apply for the 5-step process. Maryland’s catch-all qualifying-condition provision is one of the most flexible in the country — most patients with documented chronic conditions can qualify.
