A Washington medical marijuana caregiver is a designated adult authorized by a registered patient to purchase, transport, and in some cases cultivate cannabis on the patient's behalf. The role is regulated by the Washington State Department of Health, Medical Marijuana Authorization Database and exists primarily to help patients who are minors, are incapacitated, or otherwise need help managing their medication.
Minimum age: 21+. Patient ratio: 1 patient per caregiver/provider. Renewal: annually. Background check required.
