Maryland Medical Marijuana Card Guide: Documents, Application & Renewal

Maryland does things in a particular order, so it helps to understand the flow up front. You register with the Maryland Cannabis Administration (MCA) first — that gives you an MCA Patient ID Number — and your provider then uses that number to file your written certification. Registration itself is free, you can print a PDF patient ID card at no charge, and your patient ID is valid for six years (the longest in the country), though your provider certification must be renewed every year. This guide walks you through the whole process.

Documents needed to apply for a Maryland medical marijuana card

You’ll need to provide the following to register with the Maryland Medical Cannabis Program:

Medical Cannabis Certification A written certification filed by a Maryland-registered provider through the MCA’s secure online system. You will receive your certification once approved by a Kif Doctors provider — and your provider will need your MCA Patient ID Number to issue it.

Proof of Identity A Maryland driver’s license, state-issued ID card, military ID, or U.S. passport.

Proof of Residency Only Maryland residents qualify (with limited exceptions for inpatient care). An MVA registration card or title, utility bill, bank statement, or property tax bill works.

Registration with the MCA is free. You can print a PDF patient ID card at no charge; a physical MCA Patient ID card can be ordered for $25 (waived for those enrolled in the Maryland Medical Assistance Program/Medicaid or the VA Maryland Health Care System).

Next steps after approval

Congratulations on getting certified!

Because Maryland has you register before your provider can certify you, the order of steps matters. Here’s a guide on exactly what you need to do next!

Before you start, have these supporting documents ready:

A valid email address (you’ll need to verify it to complete registration)

Passport-style photo for your patient ID card (hospice patients may submit an Attending of Hospice Record physician letter instead of a photo)

Proof of Identity (one document required)

• Maryland driver’s license, state ID card, military ID, or U.S. passport

Proof of Maryland Residency (one document required)

• MVA registration card or title, utility bill, bank account statement, or property tax bill

Optional – proof for the $25 card-fee waiver

• Maryland Medical Assistance (Medicaid) enrollment, or a U.S. Department of Veterans Affairs ID card (with a valid expiration date on the front)

For minors – proof of the caregiver’s guardianship and a completed Minor Patient Form

Getting Your Maryland Medical Marijuana Card

The Maryland process runs through the Maryland OneStop Portal.

1. Register with the MCA. Create an account on the Maryland OneStop Portal (onestop.md.gov) and complete the online patient application in a single session (you can’t save and return later).
2. Verify your email. Click the verification link the system emails you — without this step, your application isn’t complete and won’t be reviewed.
3. Receive your MCA Patient ID Number. MCA reviews your application and emails you an approval that includes your Patient ID Number. Keep this email — your provider needs the number to certify you, and you’ll need it at the dispensary.
4. Consult a Maryland-registered provider. Speak with a Kif Doctors provider — a Maryland-licensed physician or other qualified provider (such as a nurse practitioner or physician assistant) registered with the MCA. Telehealth evaluations are allowed and are valid the same as in-person visits.
5. Get certified. If you have a qualifying condition, your provider files your written certification into the MCA system using your Patient ID Number.
6. Get your card. Log into your OneStop account, go to the Action tab, and view and print your PDF Patient Identification Card for free — or order the physical card for $25.
7. Designate a caregiver (optional). After approval, log into the patient registry to add a caregiver.
8. Purchase medical cannabis. Present your patient ID card and provide your MCA Patient ID Number at a licensed Maryland dispensary. Many dispensaries let you shop with a valid certification while your physical card arrives.

Please note: Most patients complete the process within a few days when their documents are ready. Registered medical patients enjoy benefits adult-use customers don’t, including exemption from the 12% adult-use sales tax, more home-cultivation plants, and access at age 18.

How to renew your Maryland medical marijuana card

It’s quick and easy to renew your Maryland medical marijuana card with Kif Doctors. Here’s what you’ll need to do:

1. Sign in to your Kif Doctors account or register as a renewal patient.
2. Speak to a Maryland-registered provider online (telehealth is available) to be reassessed.
3. Your provider files a renewed annual certification directly into your existing MCA Cannabis Patient Registry profile — it links automatically to your six-year patient ID record.
4. In most years, that’s all that’s needed: you can shop the same day at the medical-tier (0%) tax rate.
5. In a card-renewal year only (every six years), log into the Maryland OneStop Portal to renew your patient ID — upload a current photo, confirm Maryland residency, and pay the $25 fee (waived with Maryland Medicaid).

Your provider certification must be renewed annually, while your patient ID card is valid for six years. Begin your renewal about 30 days before your certification expires so your access isn’t interrupted.

Next steps after renewal

After your Kif Doctors provider files your renewed certification, you’re generally set for the year. Only in a card-renewal year do you also update your patient ID on OneStop.

Here’s what to keep in mind.

Renewing Your Maryland Medical Marijuana Card

1. Complete a telehealth or in-person evaluation with your Kif Doctors provider.
2. Your provider files the renewed annual certification into your existing MCA registry profile.
3. Confirm your certification status in your OneStop account.
4. In a card-renewal year, log in to OneStop, update your photo and residency, and pay the $25 patient ID fee (waived with Medicaid).
5. Print your updated PDF patient ID card from the Action tab, or order the physical card.

Please note: If your annual certification lapses, you can’t purchase medical cannabis (or claim the tax exemption) until it’s renewed — so renew early.

Legal limitations for cardholders

Maryland’s medical cannabis program has been operational since 2017 and is administered by the Maryland Cannabis Administration (formerly the Maryland Medical Cannabis Commission), under Health-General Article, Title 13, Subtitle 33. Adult-use cannabis was legalized by Question 4 in 2022, with sales beginning July 1, 2023.

Registered patients may purchase a 30-day supply — up to 120 grams (about 4 ounces) of usable cannabis — unless their certifying provider determines a different amount is appropriate.

Under Maryland medical cannabis law, registered patients generally have the right to:

• Be certified for a qualifying condition (such as cachexia, anorexia, wasting syndrome, severe or chronic pain, severe nausea, seizures, severe or persistent muscle spasms, glaucoma, PTSD, or another severe chronic condition unresponsive to other treatments) and purchase from licensed dispensaries at age 18 or older.
• Be exempt from the 12% adult-use sales tax with a valid MCA card at the point of sale.
• Cultivate cannabis at home — registered patients may grow up to 4 plants per household (two more than the adult-use limit of two), kept out of public view and secured from anyone under 21.
• Designate a caregiver, who may serve up to five patients.
• Be protected from employment action based solely on registered-patient status (subject to limits).

However, a Maryland medical cannabis card does not necessarily give you the right to:

• Possess more than your authorized 30-day supply.
• Use cannabis in public spaces, on federal property, in workplaces, or in a moving vehicle.
• Use or possess cannabis at your place of employment without recourse, where workplace policies apply.
• Work, live, or learn somewhere that could lose a monetary or licensing benefit under federal law due to your patient status. Some federal jobs and positions requiring a commercial driver’s license may conflict with federal law.
• Sell or distribute cannabis to others.
• Drive under the influence of cannabis — illegal regardless of how the product was purchased (cannabis in a vehicle must be sealed in its original packaging and out of the driver’s reach).
• Own a firearm — federal law prohibits possession of firearms by individuals who use marijuana, including medical patients.

Recreational adult-use cannabis is legal for those 21 and older, but only Maryland residents may register as medical patients (with limited exceptions for inpatient care). Insurance does not cover medical cannabis.

How to become a caregiver in Maryland

A caregiver purchases medical cannabis from a licensed Maryland dispensary on behalf of their designated patient(s) and transports it to them. Once registered, a caregiver must obtain a valid MCA Caregiver ID Card and may serve a maximum of five registered patients at one time.

To register as a caregiver:

• The patient designates the caregiver through the Maryland OneStop Portal after the patient’s application is approved (using the Add/Remove Caregiver function).
• The caregiver registers with the MCA and obtains their Caregiver ID Card.
• For a minor patient, a parent or legal guardian must serve as the caregiver and provide proof of guardianship.

Minor patient information

Minors (anyone under 18) cannot register on their own. A parent or legal guardian must register as the minor’s caregiver, complete the Minor Patient Form, and provide proof of guardianship. The caregiver purchases and transports the medical cannabis on the minor’s behalf.

Can I use my Maryland medical cannabis card in other states?

Within Maryland, present your patient ID card and provide your MCA Patient ID Number at licensed dispensaries. Because adult-use cannabis is legal for those 21 and older — and Maryland does not require residency for recreational purchases — visitors 21+ can buy adult-use products with a valid photo ID, though without the medical tax exemption and other benefits.

Maryland’s medical program is generally limited to residents (non-residents qualify only for inpatient care at an accredited facility). If you’re a Maryland patient traveling elsewhere, reciprocity rules vary widely by state and dispensary, and many states require a separate visiting-patient application. States commonly cited as honoring out-of-state cards include Arizona, Hawaii, Maine, Nevada, New Hampshire, New Mexico, Oklahoma, Rhode Island, Utah, and Washington, D.C.

Reciprocity policies change frequently, so always confirm a state’s current rules before you travel — and never transport cannabis across state lines, as that remains illegal under federal law.
