Washington Measure 692 allows for the legal possession, use, growing, and distribution of medical marijuana within Washington State. Patients who obtain a physician statement for medical marijuana (medical marijuana license) may legally posses up to twenty four (24) ounces of medical cannabis at any one time, use medical marijuana legally in their private residence, and obtain Washington cannabis from a certified primary caregiver. Washington medical marijuana patients may also, legally, grow up to fifteen (15) medical cannabis plants in their own private residence. Washington medical marijuana patients may not sell medical cannabis to other medical marijuana patients. A medical marijuana license does not guarantee immunity from workplace restriction on the use of medical marijuana; or housing restriction on the possession, growing, or use of medical cannabis. Driving under the influence of cannabis is prohibited under Washington Measure 692. Washington does not share reciprocity with other medical marijuana states. Potential Washington medical cannabis patients should consult with a physician, or medical cannabis registration company, to determine qualification to use medical marijuana in Washington State.
