Patients with one of the following terminal or debilitating medical conditions may qualify to participate in Washington’s medical marijuana program:
As of 2015, qualifying conditions can only be added to the list through legislation. Previously, petitions were accepted for review.

It is not necessary for a patient to go to a medical marijuana “clinic” to receive an authorization form. Patients can consult with any of the following doctors in Washington:
If the health care provider believes that cannabis is an appropriate treatment for the qualifying condition, they must complete a medical marijuana authorization form on the patient’s behalf.
The authorization form expires in 12 months for patients 18 years old and over. It expires in 6 months for patients younger than 18. However, the health care practitioner may select a shorter expiration date.
Once an authorization form has been submitted by the healthcare practitioner, the patient has two options:
In order for a minor patient to participate in Washington’s medical marijuana program, the patient’s legal guardian must provide consent for the child to engage in cannabis consumption. Additionally, the guardian must also consent to be the child’s designated provider.
Adult patients may also designate a provider. The designated provider must also receive authorization from the patient’s health care practitioner. Each patient can have only 1 designated provider, and each provider can only support one patient.
Authorized medical marijuana patients may possess the following amounts of cannabis products:
Medical marijuana patients may make tax-exempt cannabis purchases from licensed medical dispensaries.
