Washington Initiative 692 (1998)
Washington's 1998 medical cannabis law created an affirmative defense, not dispensaries or legal immunity.
I-692 is remembered as Washington's 'medical marijuana law,' but it did almost none of what people think. It didn't create dispensaries, legal immunity, or a registry. It only said patients could use an affirmative defense if arrested. Everything familiar about Washington's medical program—storefronts, plant counts, patient cards—came from laws written years later, mostly after 2011.
Background: the 1996–1998 medical cannabis wave
California's Proposition 215 passed in November 1996, establishing the first state-level medical cannabis law in the United States Strong evidence[1]. Activists in other Western states moved quickly. In Washington, an earlier initiative—I-685, a broader drug-policy measure modeled partly on Arizona's Proposition 200—appeared on the November 1997 ballot and was defeated, with roughly 60% voting no Strong evidence.
Organizers regrouped under the name Washington Citizens for Medical Rights and drafted a narrower successor focused strictly on medical cannabis use. That measure became Initiative 692. The campaign was backed financially by the same national donors active in other 1990s drug-policy reform efforts, including financier George Soros, Peter Lewis of Progressive Insurance, and University of Phoenix founder John Sperling[2].
What I-692 actually authorized
The full text of I-692 was codified as Chapter 69.51A of the Revised Code of Washington (RCW), titled the Medical Use of Marijuana Act Strong evidence[3].
Qualifying conditions. The statute enumerated specific conditions: cancer, HIV/AIDS, multiple sclerosis, epilepsy or other seizure disorders, glaucoma, intractable pain, and certain other 'terminal or debilitating' conditions. The state Department of Health was authorized to add conditions by rule Strong evidence[3].
Authorization, not prescription. A licensed physician had to provide 'valid documentation' that the patient might benefit from medical use. Federal law barred actual prescriptions, so the statute used the term authorization Strong evidence[3].
Sixty-day supply. Patients or their designated 'primary caregiver' could possess a 60-day supply for personal medical use. The initiative itself did not define that amount in grams or plants; quantification came later by Department of Health rule Strong evidence[3][4].
Affirmative defense, not immunity. A qualifying patient who was arrested could raise medical use as an affirmative defense at trial. Police were not required to decline arrest, and the burden of proof sat with the patient Strong evidence[3].
No dispensaries, registry, or commercial supply chain. I-692 created no licensed retail system, no patient registry, and no legal way to purchase cannabis. Patients had to grow their own or rely on a single designated caregiver Strong evidence[3].
This structure is critical for understanding later disputes: virtually every familiar feature of 'medical marijuana in Washington'—collective gardens, storefronts, the patient registry, specific plant counts—was added by subsequent legislation, not by I-692 itself Strong evidence[4][5].
Campaign and 1998 election
The Yes on 692 campaign emphasized seriously ill patients—cancer and AIDS patients in particular—and explicitly distinguished itself from the broader, defeated I-685. Public endorsements came from a range of hospice and HIV/AIDS care providers[6].
Opposition was led by law enforcement organizations, including the Washington Association of Sheriffs and Police Chiefs, and by then–U.S. drug czar Barry McCaffrey's office, which campaigned against medical cannabis initiatives nationally during this period[6].
On November 3, 1998, I-692 passed with roughly 59% in favor Strong evidence. That same election cycle, voters in Oregon, Alaska, and Nevada approved their own medical cannabis measures, creating a second wave of state-level medical programs following California's 1996 initiative Strong evidence[1].
Implementation gaps and litigation, 1999–2010
Because I-692 provided only an affirmative defense, patients were routinely arrested, had medicine seized, and had to litigate their status case by case throughout the 2000s. Washington appellate decisions repeatedly addressed who qualified, what counted as 'valid documentation,' and how the 60-day supply rule should be applied Strong evidence[4].
In 2008, the Department of Health adopted a presumptive 60-day supply rule of 24 ounces of usable cannabis and up to 15 plants—a number that itself drew subsequent litigation and policy debate Strong evidence[4].
The legislature substantially rewrote the medical program in 2007 (SB 6032) and again in 2011 (SB 5073). SB 5073 attempted to create licensed dispensaries and a patient registry; Governor Christine Gregoire vetoed most of the licensing sections, citing federal preemption concerns after U.S. Attorneys threatened state employees with prosecution. What survived authorized 'collective gardens,' which became the legal framework for the gray-market dispensaries that proliferated in Seattle and other cities from 2011 onward Strong evidence[5].
Transition after [Initiative 502](washington-initiative-502-2012) and SB 5052
Voters approved Initiative 502 in November 2012, legalizing adult-use cannabis Strong evidence. I-502 did not repeal I-692, but it set the stage for tension between an unregulated medical market and a heavily taxed and tested recreational one.
In 2015, the legislature passed SB 5052, the Cannabis Patient Protection Act, which folded medical sales into the recreational licensing system run by the Washington State Liquor and Cannabis Board, created a voluntary patient database, and shut down the collective garden model effective July 1, 2016 Strong evidence[7]. After that date, most of the operational machinery that patients and journalists called 'the I-692 system' no longer existed in its original form, though the underlying RCW 69.51A authorization framework remains in force Strong evidence[3].
Common myths
Myth: I-692 created medical dispensaries in Washington. It did not Disputed[3][5]. The initiative authorized personal possession and a single designated caregiver. Storefront access came from the 2011 collective garden provisions and informal local tolerance, not from I-692.
Myth: I-692 made medical cannabis 'legal' in Washington. Strictly speaking, it created an affirmative defense to a criminal charge Disputed. Qualifying patients could still be arrested and prosecuted, and many were throughout the 2000s.
Myth: Washington was the first medical cannabis state. California's Proposition 215 preceded I-692 by two years Strong evidence[1]. Washington was part of the 1998 second wave alongside Oregon, Alaska, and Nevada.
Myth: The 60-day supply was always 24 ounces and 15 plants. Those numbers came from a 2008 Department of Health rulemaking, not from the 1998 initiative text, which left the quantity undefined Strong evidence[4].
