November 03, 1998, Ballot Measure 67 was approved, legally removing all state-level criminal penalties on the use, possession and cultivation of marijuana by patients with a signed recommendation from their physician stating that marijuana “may mitigate” his or her debilitating symptoms.

January 01, 2006, Senate Bill 1085, effectively amended “The Oregon Medical Marijuana Act”, such that state-qualified patients who possess amounts of cannabis exceeding the new state guidelines, will no longer retain the ability to argue an “affirmative defense” of medical necessity, in case of a trial. However, patients in possession of medical cannabis in amounts compliant with state law, retain the ability to use an “affirmative defense.” In addition, the amendment redefines “mature plants” to specifically include only those cannabis plants, that are more than 12 inches in height and diameter. And, established a state patient registry for those authorized to cultivate cannabis for qualified patients.

July 21, 1999, House Bill 3052, authorized patients, or appointed caregivers, cultivating medical cannabis, to do so, only, in one location. As per HB 3052, patients must be diagnosed with a qualifying medical condition for at least 12 months prior to being arrested, in order to be allowed to use an “affirmative defense.” HB 3052 also contains instructions to add the agitation of Alzheimer’s disease to the list of qualifying medical conditions.

In August 2001, a modification to the law requires that patients establish a bonafide physician relationship — “a physician who has established a physician/patient relationship with the patient … is primarily responsible for the care and treatment of the patients … has reviewed a patient’s medical records at the patient’s request, has conducted a thorough physical examination of the patient, has provided a treatment plan and/or follow-up care, and has documented these activities in a patient file.”

June 06, 2013, Governor John Kitzhaber, officially added post-traumatic stress disorder (PTSD) to the list of approved qualifying medical marijuana conditions.

August 14, 2013, HB 3460, created a state dispensary program, by allowing for the state licensing and regulation of medical marijuana facilities.

March 19, 2014, Senate Bill 1531, allows local governments to restrict the operation of medical marijuana dispensaries, in addition to the moratoriums through May 01, 2015.

April 18, 2014,15 dispensary locations were approved by the Oregon Medical Marijuana Dispensary Program.  July 01, 2015, HB 3400, requires that patients be state residents, in order to qualify for the program.
The Oregon Revised Statutes ORS 475.300 — ORS 475.346, limits registry I.D. cardholders and designated primary caregivers of cardholders, from possessing no more than six mature marijuana plants, 24 ounces of usable marijuana, and a combined total of up to eighteen marijuana seedlings.
