Rhode Island statute and program

The Rhode Island Medical Marijuana Program (Edward O. Hawkins and Thomas C. Slater Medical Marijuana Act) is the operating authority for Rhode Island patient certification. The authoritative legal text is: Rhode Island General Laws Chapter 21-28.11: The Rhode Island Cannabis Act. The program portal is at Rhode Island Medical Marijuana Program (Edward O. Hawkins and Thomas C. Slater Medical Marijuana Act).

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 Rhode Island

The Rhode Island Medical Marijuana Program (Edward O. Hawkins and Thomas C. Slater Medical Marijuana Act) requires the following registration steps for a Complex Regional Pain Syndrome patient (or any qualifying diagnosis):

  1. Get a written certification from a Rhode Island healthcare practitioner. Any Rhode Island-licensed physician, physician assistant, advanced practice nurse, or out-of-state physician with a Rhode Island Medical Marijuana Program registration may issue the written certification stating that the patient has a debilitating medical condition under R.I. Gen. Laws §21-28.6-3. The Edward O. Hawkins / Thomas C. Slater Act permits practitioner-added "other medical condition or its treatment" beyond the enumerated list.
  2. Submit your patient application to the Office of Cannabis Regulation. The patient mails the completed Patient Registration Application, the Written Certification, a Rhode Island driver license or state ID copy, a passport-style photograph, and the registration fee to the Office of Cannabis Regulation at the Department of Business Regulation (DBR). Online submission is available through the DBR portal.
  3. Pay the $50 state registration fee. The annual patient registration card fee is $50, reduced to $10 for patients on Medicaid or SSI. Caregivers are $50 per caregiver with a separate background check. Compassion-center registration (the alternative for patients who do not want to register with a caregiver) carries the same fee structure.
  4. Receive the card and purchase from a compassion center. Patient registration cards are issued within roughly 35 days of complete application receipt. With the card, patients may purchase up to 2.5 ounces every 15 days from any Rhode Island licensed compassion center. Rhode Island honors out-of-state medical cards from qualifying states for purchase at compassion centers under its reciprocity statute. Adult-use retail also operates statewide for adults 21+.

ICD-10 code

A certifying physician documenting Complex Regional Pain Syndrome for the Rhode Island 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 Rhode Island list Complex Regional Pain Syndrome as a qualifying condition for medical cannabis?

Not by name, but Rhode Island permits physician discretion. Under Rhode Island Medical Marijuana Program (Edward O. Hawkins and Thomas C. Slater Medical Marijuana Act), 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 Rhode Island medical marijuana card for Complex Regional Pain Syndrome?

Step one is finding a physician licensed in Rhode Island who is registered with Rhode Island Medical Marijuana Program (Edward O. Hawkins and Thomas C. Slater Medical Marijuana Act) 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. Rhode Island honors out-of-state medical cards under its reciprocity rules — uncommon, and worth verifying before relying on it. Verify the patient minimum age with the state program before applying. The authoritative source for the current process is the Rhode Island Medical Marijuana Program (Edward O. Hawkins and Thomas C. Slater Medical Marijuana Act) site at https://dbr.ri.gov/divisions/medical-marijuana; the state updates fees, forms, and physician registration rules periodically.

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.
