Maryland statute and program

The Maryland Medical Cannabis Program is the operating authority for Maryland patient certification. The authoritative legal text is: Md. Code, Alcoholic Beverages and Cannabis Article: Title 36.

What the evidence says about cannabis and Complex Regional Pain Syndrome

CRPS Type I follows soft-tissue injury, fracture, or surgery without identifiable nerve injury. CRPS Type II follows confirmed peripheral nerve injury. Diagnosis is clinical, based on the Budapest Criteria (International Association for the Study of Pain), which require disproportionate pain plus signs and symptoms across multiple of four categories (sensory, vasomotor, sudomotor/edema, motor/trophic).

For the full evidence base, including the NASEM tier, randomized trial summaries, and symptom-domain breakdown, read the mmjnow Complex Regional Pain Syndrome page.

How to qualify in Maryland

The Maryland Medical Cannabis Program requires the following registration steps for a Complex Regional Pain Syndrome patient (or any qualifying diagnosis):

  1. Register as a patient with the Maryland Cannabis Administration (MCA). Patients self-register through the MCA online patient portal before seeing a provider. Registration requires a Maryland driver license or state ID, a passport-style photograph, and proof of Maryland residency. Out-of-state patients with a qualifying condition may also register and are issued a 30-day temporary identification card.
  2. Get certified by an MCA-registered provider. A Maryland-licensed physician, dentist, podiatrist, advanced practice registered nurse, nurse midwife, or physician assistant registered with the MCA must issue a written certification documenting a qualifying condition such as chronic pain, severe nausea, seizures, glaucoma, PTSD, or another condition the provider determines may benefit from medical cannabis. Telehealth certifications are accepted.
  3. Pay the $25 patient registration fee. The MCA patient identification card fee is $25 for a three-year registration (reduced from the original $50 under 2024 Maryland Cannabis Administration reforms). Caregiver registration is $50 per caregiver. Renewals require updated provider certification at the end of the three-year period.
  4. Purchase from licensed Maryland dispensaries. With the MCA registration ID, patients may purchase from any licensed Maryland medical-cannabis dispensary up to a 30-day supply (defined by potency-adjusted dosage units rather than weight). Adult-use retail launched July 1, 2023; patients retain medical-only product access, lower taxation, and statutory employment and family-court protections under the Maryland Medical Cannabis Act.

ICD-10 code

A certifying physician documenting Complex Regional Pain Syndrome for the Maryland medical cannabis program will typically record ICD-10 G90.50 or SNOMED-CT 128200000 in the patient's record. The state registry does not itself collect ICD-10 codes in most programs, but the physician's chart is the audit trail if the certification is later reviewed.

Frequently asked questions

Does Maryland list Complex Regional Pain Syndrome as a qualifying condition for medical cannabis?

Not by name, but Maryland permits physician discretion. Under Maryland Medical Cannabis Program, a certifying physician can add a condition like Complex Regional Pain Syndrome on a case-by-case basis when the physician judges that the patient would benefit from medical cannabis. This is different from a state where the qualifying-condition list is fixed in statute. Whether a particular physician will certify Complex Regional Pain Syndrome depends on the physician's training, the strength of the patient's documentation, and the practitioner's reading of the available evidence — evidence is described as limited (a small number of supportive studies, often underpowered or focused on narrow symptom domains). Patients should expect to bring full diagnostic records to the certification visit.

How do I get a Maryland medical marijuana card for Complex Regional Pain Syndrome?

Step one is finding a physician licensed in Maryland who is registered with Maryland Medical Cannabis Program and willing to evaluate Complex Regional Pain Syndrome cases. Step two is collecting your records (diagnosis documentation, treatment history, and the ICD-10 code your physician will use) and bringing them to the certification visit. Step three is the physician's certification through the state registry, followed by the patient registration application, state fee, and waiting period before the card is issued. Maryland does not honor out-of-state cards, so the certification process has to originate inside the state. Verify the patient minimum age with the state program before applying. Confirm the current process with the state regulator before applying, because the rules change.

What does the evidence say about cannabis for Complex Regional Pain Syndrome?

For Complex Regional Pain Syndrome, evidence is described as limited (a small number of supportive studies, often underpowered or focused on narrow symptom domains). The mmjnow condition page for Complex Regional Pain Syndrome lays out the current evidence base, including the citations underlying that evidence tier — typically the National Academies of Sciences, Engineering, and Medicine consensus reports, federal agency guidance, and peer-reviewed reviews. Evidence quality is independent of state law: a state can list a condition for which evidence is limited, and a state can decline to list a condition for which evidence is strong. Patients deciding whether to pursue medical cannabis for Complex Regional Pain Syndrome should review the underlying evidence (linked on the condition page) and discuss expected benefit, dosing, and risk with a clinician familiar with both Complex Regional Pain Syndrome and cannabinoid pharmacology. Cannabis is not a substitute for evidence-based first-line treatments for Complex Regional Pain Syndrome; the evidence position above describes whether trial data supports its use, not whether it should replace standard care.
