Medical marijuana cooperatives allow up to four medical marijuana patients or their designated provider to join together to grow marijuana for the patients' personal use.
Every member must be entered into the medical marijuana authorization database and have a medical marijuana recognition card. The total number of plants authorized for the participants may not exceed 60 plants.
Cooperatives must register with the Washington State Liquor and Cannabis Board (WSLCB) and follow all regulations.
