Washington Legal Information

In 1998, Washington voters approved state Initiative Measure No. 692, allowing a qualifying patient or designated provider to have a 60-day supply of medical cannabis, later defined as 24 ounces and 15 plants. Qualifying patients and caregivers within those limits are protected from arrest and prosecution; a patient who exceeds those limits is entitled to an affirmative defense of medical necessity. Designated providers must be 18 years of age or older. Dispensaries are not permitted under Washington law, but up to ten (10) patients may participate in a collective garden of 45 plants or less. In 2011, the state legislature changed also the requirements for recommending cannabis to patients; currently, recommendations must be on tamper-resistant paper and include an original signature by the healthcare provider, a date, and a statement that the patient may benefit from the medical use of marijuana. In November 2012, voters passed Initiative 502 relating to the adult use of cannabis, but that law does not directly affect the rights and protections afforded to patients.

In 2015, the state approved SB 5052, which establishes state regulated medical cannabis retail access points utilizing the I-502 retail stores and made significant changes to the state's patient cultivation rights. Collective gardens will no longer be allowed as of July 2016, but can apply to form non-commercial cooperatives to provide an alternative to access from retail stores.

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. If you are arrested for a marijuana offense and the prosecutor files charges, you will first face an arraignment, where you will plead guilty or not guilty. If you plead not guilty, you will have various motions hearings and eventually you may go to trial before a jury or judge, and the process may take a significant amount of time.
