Oregon's Medical Marijuana Laws & Regulations

The Oregon Medical Marijuana Act (OMMA) was passed by Oregon voters on November 3, 1998, and went into effect on December 3, 1998. The law allows a patient with a valid ID card to use, possess, and cultivate cannabis for medicinal purposes, as well as designate a primary caregiver to help them with their medicine.

The Oregon Health Authority regulates OMMA through the Oregon Medical Marijuana Program (OMMP). Patients must enroll in the state patient registry and possess a valid identification card in order to be protected from arrest. Patients who are not registered with the OMMP, but who have a valid recommendation for a qualifying condition and are within the possession or cultivation limits set by the OMMA are entitled to present an affirmative defense. 

On August 14, 2013, Gov. John Kitzhaber signed House Bill 3460 into law, establishing regulations for the creation of state-licensed medical cannabis facilities. The Oregon Health Authority developed rules and regulations and has oversight of the new statewide distribution system. The rules have been in place since January 31, 2014, allowing time for the Oregon Health Authority to establish a process for the submission of applications for dispensaries by March 1, 2014, as required by the provisions of HB 3460. However, in early 2014, the Oregon Legislature passed SB 1531, which grants cities and counties the right to pass moratoriums on the opening of medical marijuana facilities in their jurisdiction until May 1, 2015.

The 2015 legislative session brought three more bills that make changes to the medical cannabis program. HB 3400 which primarily changed residency requirements for growers, SB 460 which allowed dispensaries to temporarily serve the new legal adult-use cannabis market before the official opening of adult-use retail distribution, and SB 844 which developed a task for to evaluate medical and public health effects of cannabis.
