Massachusetts statute and program

The Massachusetts Medical Use of Marijuana Program is the operating authority for Massachusetts patient certification. The authoritative legal text is: M.G.L. Chapter 94G: Regulation of the Use and Distribution of Marijuana Not Medically Prescribed. The program portal is at Massachusetts Medical Use of Marijuana Program.

What the evidence says about cannabis and Parkinson's Disease

Parkinson's disease (PD) is a progressive neurodegenerative disorder caused by the loss of dopamine-producing neurons in the substantia nigra. Cardinal motor symptoms include resting tremor, bradykinesia, rigidity, and postural instability. Non-motor symptoms (sleep disturbance, depression, anxiety, autonomic dysfunction, cognitive change) often precede motor onset and contribute substantially to disease burden.

For the full evidence base, including the NASEM tier, randomized trial summaries, and symptom-domain breakdown, read the mmjnow Parkinson's Disease page.

How to qualify in Massachusetts

The Massachusetts Medical Use of Marijuana Program requires the following registration steps for a Parkinson's Disease patient (or any qualifying diagnosis):

  1. Get certified by a Massachusetts-licensed certifying healthcare provider. A Massachusetts-licensed physician, certified nurse practitioner, or physician assistant registered with the Cannabis Control Commission (CCC) Medical Use of Marijuana Program must establish a bona-fide provider-patient relationship and certify a debilitating condition. CCC regulations allow providers to certify enumerated conditions (cancer, glaucoma, HIV/AIDS, hepatitis C, ALS, Crohn’s, Parkinson’s, MS) plus "other conditions determined by a qualifying provider" — broad practitioner discretion.
  2. Complete the online patient registration via Virtual Gateway. After certification, the provider creates a Virtual Gateway PIN that the patient uses to complete the online registration through the Massachusetts Cannabis Control Commission MMJ Online System. Patients upload a Massachusetts driver license or state ID and a passport-style photo.
  3. Pay the $50 state fee (or qualify for fee waiver). The annual program registration fee is $50, waived for veterans, low-income patients (verified through MassHealth, SNAP, SSI, SSDI, or Veterans Affairs benefits documentation), and hospice patients. Temporary patient registration cards are emailed within several business days of approval; physical cards arrive within roughly two to three weeks.
  4. Purchase from a Massachusetts medical marijuana treatment center. With the temporary or physical card, patients may purchase up to a 60-day supply (default 10 ounces) from any of the licensed Massachusetts Medical Marijuana Treatment Centers. Adult-use retail exists statewide for adults 21+, but the medical registration provides access to medical-only products, no excise tax, higher possession limits, and family-court and workplace protections under M.G.L. c. 94I.

ICD-10 code

A certifying physician documenting Parkinson's Disease for the Massachusetts medical cannabis program will typically record ICD-10 G20 or SNOMED-CT 49049000 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 Massachusetts list Parkinson's Disease as a qualifying condition for medical cannabis?

Yes. Massachusetts explicitly lists Parkinson's Disease as a qualifying condition under Massachusetts Medical Use of Marijuana Program. A patient with a documented Parkinson's Disease diagnosis can pursue state-program certification with a physician registered in the state. The qualifying-condition list is published by the state at https://masscannabiscontrol.com/medical-use/ and may change as regulators add, remove, or refine entries. Inclusion on the list does not guarantee certification — a physician still has to evaluate the patient and decide that medical cannabis is appropriate for that specific case under Massachusetts rules.

How do I get a Massachusetts medical marijuana card for Parkinson's Disease?

Step one is finding a physician licensed in Massachusetts who is registered with Massachusetts Medical Use of Marijuana Program and willing to evaluate Parkinson's Disease 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. Massachusetts 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. The authoritative source for the current process is the Massachusetts Medical Use of Marijuana Program site at https://masscannabiscontrol.com/medical-use/; the state updates fees, forms, and physician registration rules periodically.

What does the evidence say about cannabis for Parkinson's Disease?

For Parkinson's Disease, evidence is described as limited (a small number of supportive studies, often underpowered or focused on narrow symptom domains). The mmjnow condition page for Parkinson's Disease 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 Parkinson's Disease should review the underlying evidence (linked on the condition page) and discuss expected benefit, dosing, and risk with a clinician familiar with both Parkinson's Disease and cannabinoid pharmacology. Cannabis is not a substitute for evidence-based first-line treatments for Parkinson's Disease; the evidence position above describes whether trial data supports its use, not whether it should replace standard care.
