Maryland Medical Cannabis Certification

🏥 Two-Step Process

Getting your Maryland medical cannabis certification involves two steps: completing your Maryland state registration and then seeing a certifying provider.

State of Maryland (MCA) — manages patient registration through OneStop and issues your MCA Patient ID Number.

Green Bridge — helps guide you through the process and connects you with a certifying provider once your Maryland registration is complete.

💰 Why Get a Medical Card When Rec Is Legal in MD?

Maryland legalized recreational cannabis in 2023, but medical patients still get real advantages:

✅ No 9% sales tax on medical purchases — recreational buyers pay it on every transaction

✅ Higher purchase limits — 120g per 30 days vs. recreational's 1.5oz cap per transaction

✅ Access at 18+ — recreational requires 21+

✅ More product variety — medical-only products like high-dose edibles and concentrates

📋 Maryland Requires State Registration First

Maryland patients should complete their state registration in OneStop before scheduling with a certifying provider. Once approved, you'll receive an MCA Patient ID Number, which is needed for certification.

📞 How Doctor Calls Work

Our doctors call patients in the morning, afternoon, and evening — including weekends if scheduled on a Friday. You'll complete a short intake when you schedule.

Calls may come from a private, unknown, or spam-labeled number, so please keep your phone nearby and turned on.

📄 Registration Requirements

Maryland requires patients to register through OneStop before certification. Because registration requires sensitive personal information, including your full 9-digit Social Security Number, we recommend that patients complete this step themselves whenever possible.

✅ A valid, accessible email account

✅ Your full 9-digit SSN (entered directly in OneStop)

✅ A valid government-issued photo ID (MD driver's license, state ID, military ID, or passport)

✅ A recent passport-style photo (white/off-white background, square, taken within 6 months)

✅ Proof of Maryland residency (dated within 90 days)

📸 Photo Requirements (Common Rejection Reason)

MCA is strict about photos. To avoid your application being returned:

✅ File type: .jpg, .png, or .gif only

✅ Max size: 3 MB

✅ Square image: 600×600 px minimum, 1200×1200 px maximum

✅ Plain white or off-white background

✅ Taken within the last 6 months

❌ No hats, sunglasses, filters, or heavy shadows

Maryland uses qualifying-condition language that includes:

• Severe or chronic pain

• PTSD

• Severe nausea

• Seizures

• Severe or persistent muscle spasms

• Glaucoma

• Cachexia / anorexia / wasting syndrome

• Any other chronic medical condition which is severe and for which other treatments have been ineffective

⏳ 120-Day First Purchase Rule

If your certification is not used to make a purchase at a Maryland dispensary within 120 days, it becomes void.

📊 Rolling 30-Day Purchase Limit

Maryland tracks purchases on a rolling 30-day basis. Patients may purchase up to 120g of flower or the equivalent within that window.

🪪 Physical ID Card Is Optional

You do not need a physical MCA ID card to purchase at a dispensary. Patients can print a paper ID card at no charge through OneStop, and a physical card is optional for $25.

🔄 Registration & Certification Timelines

Patient registration is valid for 6 years.

Doctor certification must be renewed annually.
