Washington Medical Marijuana Qualification

Who Qualifies for Medicinal Marijuana in Washington

On November 3, 1998, 59% of Washington voters approved Measure 692, which removes state-level criminal penalties on the use, possession and cultivation of medical marijuana (also referred to as medical weed, medical pot or medical cannabis) by patients who possess "valid documentation" from their physician affirming that he or she suffers from a debilitating condition and that the "potential benefits of the medical use of marijuana would likely outweigh the health risks."  Patients who possess larger quantities of cannabis than those approved by the Department will continue to receive legal protection under Washington's medical marijuana law if they present evidence indicating that they require such amounts to adequately treat their qualifying medical condition.

Medical Marijuana Access

Some medical marijuana patients will claim they have a doctor's prescription for medical marijuana, but marijuana prescriptions are in fact illegal. The federal government classifies marijuana as a schedule I drug. Therefore doctors are unable to prescribe marijuana to their patients, and medical marijuana patients cannot go to a pharmacy to fill a prescription for medical marijuana. Instead, medical marijuana physicians will supply patients with a medical marijuana recommendation in compliance with state law.

According to Washington medical marijuana laws, patients and their caregivers may grow medical marijuana for the patient's private use and may possess a "sixty-day supply." While Washington's original medical marijuana laws do not include provisions for the selling or distributing of medical cannabis, Seattle Mayor Mike McGinn signed a new law in July 2011 that will allow medical marijuana dispensaries to be regulated in Seattle like any legal business. Please note that your recommendation is valid as long as your physician deems necessary.
