Medical Cannabis Cooperatives


Medical cannabis cooperatives allow up to four medical cannabis patients or their designated provider to join together to grow cannabis for the patients' personal use.

Every member must be entered into the medical cannabis authorization database and have a medical cannabis 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.

Cooperative members may only:

  • Be in a cooperative if they have a valid medical cannabis recognition card.
  • Form a four member cooperative.
  • Participate in a cooperative if they are at least 21 years of age.
  • Grow up to the total number of plants authorized, with a maximum of 60 plants.
  • Belong to one cooperative.
  • Grow plants in the cooperative and not anywhere else.
  • Use the cannabis and its products, and not sell or give away cannabis or cannabis products to anyone who is not in the cooperative.

A cooperative must be:

  • Located at one of the member's homes.
  • Limited to one cooperative per tax parcel.
  • Enclosed by an eight-foot fence, if outdoors, and cannot easily be seen or smelled.

No cooperative may be located in any of the following areas:

  • Within one mile of a cannabis retailer;
  • Within the smaller of either:
    • 1,000 feet of schools, playgrounds, recreation centers, daycare centers, or any facility restricted to people 21 years or older, or
    • The area restricted by ordinances; or
    • Where prohibited by city, town, or county zoning laws.
