What the evidence says about cannabis and Obsessive-Compulsive Disorder

repetitive behaviors or mental acts performed in response to obsessions, aimed at reducing anxiety or preventing a feared outcome. The behaviors are not realistically connected to what they aim to prevent or are clearly excessive.

How to qualify in Connecticut

The Connecticut Medical Marijuana Program requires the following registration steps for a Obsessive-Compulsive Disorder patient (or any qualifying diagnosis):

  1. Get certified by a Connecticut-licensed physician, APRN, PA, dentist, or podiatrist. A Connecticut-licensed practitioner registered with the Department of Consumer Protection (DCP) Medical Marijuana Program must evaluate the patient and certify the qualifying condition through the DCP physician portal. Telehealth certifications are accepted when the practitioner has a bona-fide treatment relationship with the patient.
  2. Register through the DCP patient portal. After certification, the patient completes the online registration at the DCP Medical Marijuana Program portal, uploads a Connecticut driver license or state ID, and submits a passport-style photograph. Caregivers register through the same portal and undergo a state and federal criminal background check.
  3. Pay the $100 state registration fee and receive the temporary certificate. The annual state registration fee is $100, paid by credit card or check at portal submission. A temporary certificate is issued by email within several business days and is accepted by Connecticut medical dispensaries pending arrival of the physical card. The card is renewed annually with a new physician certification and fee payment.
  4. Purchase from a Connecticut medical dispensary. With the temporary certificate or physical card, patients may purchase up to the physician-set monthly allocation (default 2.5 ounces per month) from any of Connecticut's licensed medical dispensaries. Adult-use retail also exists statewide; the medical card preserves access to medical-only products, lower taxation, and protections at workplaces and in family-law matters.

ICD-10 code

A certifying physician documenting Obsessive-Compulsive Disorder for the Connecticut medical cannabis program will typically record ICD-10 F42.9 or SNOMED-CT 191736004 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 Connecticut list Obsessive-Compulsive Disorder as a qualifying condition for medical cannabis?

Not by name, but Connecticut permits physician discretion. Under Connecticut Medical Marijuana Program, a certifying physician can add a condition like Obsessive-Compulsive Disorder 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 Obsessive-Compulsive Disorder 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 insufficient (no high-quality controlled data is available either for or against). Patients should expect to bring full diagnostic records to the certification visit.

How do I get a Connecticut medical marijuana card for Obsessive-Compulsive Disorder?

Step one is finding a physician licensed in Connecticut who is registered with Connecticut Medical Marijuana Program and willing to evaluate Obsessive-Compulsive Disorder 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. Connecticut 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 Obsessive-Compulsive Disorder?

For Obsessive-Compulsive Disorder, evidence is described as insufficient (no high-quality controlled data is available either for or against). The mmjnow condition page for Obsessive-Compulsive Disorder 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 Obsessive-Compulsive Disorder should review the underlying evidence (linked on the condition page) and discuss expected benefit, dosing, and risk with a clinician familiar with both Obsessive-Compulsive Disorder and cannabinoid pharmacology. Cannabis is not a substitute for evidence-based first-line treatments for Obsessive-Compulsive Disorder; the evidence position above describes whether trial data supports its use, not whether it should replace standard care.
