Oregon Legal Information

In 1998, Oregon voters approved the Oregon Medical Marijuana Act (OMMA), allowing a patient with a valid ID card to use, possess, and cultivate cannabis for medicinal purposes, and designate a primary caregiver to assist them. Qualifying patients may possess up to 24 ounces of usable cannabis and may cultivate up to 24 plants (6 mature, 18 immature). To be protected from arrest, patients must enroll in the Oregon Health Authority patient registry and possess a valid Oregon Medical Marijuana Program (OMMP) identification card. Non-registered patients with a valid recommendation who are within the possession or cultivation limits set by the OMMA are entitled to an affirmative defense.

In August 2013, HB 3460 established regulations for state-licensed medical cannabis facilities. In March 2014, SB 1531 granted cities and counties the right to pass moratoriums on the opening of medical marijuana facilities until May 1, 2015. There are currently over 300 state licensed dispensaries serving patients. In 2016, the legislature passed HB 1404 allowing out-of-state ownership/investment in medical cannabis businesses and SB 1524 reduces paperwork requirements for veterans.

Facing state or federal charges?

Unfortunately, patients, caregivers, and providers are still vulnerable to federal and state arrests, prosecutions, and incarceration. They also suffer pervasive discrimination in employment, child custody, housing, public accommodation, education and medical care.
