6 things to know about Oregon's medical marijuana program

The Oregon Medical Marijuana Program (OMMP) is run by the Oregon Health Authority and keeps a registry of patients, caregivers and growers. Oregon residents with a listed condition get a signed Attending Provider Statement from an MD, DO, physician associate, nurse practitioner, clinical nurse specialist, CRNA or naturopathic physician, then apply online through the OMMP system. The basic fee is $200, with steep discounts for SNAP, Oregon Health Plan, SSI and veterans. Cards last one year. Although adult-use cannabis is legal, registration still lets patients possess far more (24 ounces), grow at registered sites and designate caregivers and growers.

6 things to know

1. Oregon lets several provider types sign, including nurse practitioners, physician associates and naturopathic physicians, not just MDs and DOs.
2. Veterans with a service-connected disability rating of 50% or more register for free.
3. Registered patients may possess up to 24 ounces of usable marijuana, well above adult-use limits.
4. A grow site registration fee of $200 applies when the site is not the patient's home, someone else grows, or the site exceeds 12 mature plants.
5. The program is now part of OHA's Medical Cannabis & Psilocybin Section.
6. OMMP fees are non-refundable and only one reduced-fee category can be claimed.
