What the evidence says about cannabis and Crohn's Disease

Crohn's disease is a chronic inflammatory bowel disease that causes inflammation of the digestive tract, leading to abdominal pain, severe diarrhea, weight loss, fatigue, and malnutrition. The inflammation can occur anywhere from the mouth to the anus, often in patchy distributions. Severity varies widely; some patients experience prolonged remissions on biologic therapy, while others require multiple surgeries.

How to qualify in Montana

The Montana Medical Marijuana Program requires the following registration steps for a Crohn's Disease patient (or any qualifying diagnosis):

  1. Get certified by a Montana-licensed physician. Under Mont. Code Ann. §50-46-301 et seq. (Montana Marijuana Regulation and Taxation Act, voters approved 2004 and modernized 2021), any Montana-licensed MD, DO, advanced practice registered nurse, or physician assistant authorized to prescribe controlled substances may certify a patient. Qualifying debilitating medical conditions include cancer, glaucoma, HIV/AIDS, MS, epilepsy, intractable nausea, severe chronic pain, cachexia, severe muscle spasms, PTSD, Crohn’s, central nervous system disorders, painful peripheral neuropathy, and admittance to hospice care.
  2. Apply through the Montana DPHHS portal. The patient creates an account in the Montana Department of Public Health and Human Services (DPHHS) Cannabis Control Division registry portal, uploads the physician certification, a Montana driver license or state ID, and a passport-style photograph. Caregivers (called "providers" under Montana law) register separately and pass a state background check.
  3. Pay the $5 state registration fee. The annual Montana medical marijuana registry card fee is $5 — among the lowest in the United States. Patients pay only this nominal state fee plus the physician certification fee. Caregivers pay a separate higher provider licensing fee through the Cannabis Control Division.
  4. Receive the card and purchase from a Montana dispensary. Montana medical marijuana registry cards are typically issued within 5 to 10 business days of complete application. Patients may purchase up to 5 ounces of usable cannabis per month from any of the licensed Montana medical dispensaries and may cultivate up to 4 mature plus 4 seedling plants. Adult-use retail launched January 1, 2022 under HB 701 (2021); medical patients retain the lower 4% medical tax versus the 20% adult-use rate and access to higher-potency products.

ICD-10 code

A certifying physician documenting Crohn's Disease for the Montana medical cannabis program will typically record ICD-10 K50.90 or SNOMED-CT 34000006 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 Montana list Crohn's Disease as a qualifying condition for medical cannabis?

Yes. Montana explicitly lists Crohn's Disease as a qualifying condition under Montana Medical Marijuana Program. A patient with a documented Crohn'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://dphhs.mt.gov/marijuana 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 Montana rules.

How do I get a Montana medical marijuana card for Crohn's Disease?

Step one is finding a physician licensed in Montana who is registered with Montana Medical Marijuana Program and willing to evaluate Crohn'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. Montana 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 Montana Medical Marijuana Program site at https://dphhs.mt.gov/marijuana; the state updates fees, forms, and physician registration rules periodically.

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

For Crohn'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 Crohn'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 Crohn'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 Crohn's Disease and cannabinoid pharmacology. Cannabis is not a substitute for evidence-based first-line treatments for Crohn's Disease; the evidence position above describes whether trial data supports its use, not whether it should replace standard care.
