Bottom line: we can protect the health and safety of your end users — and the success of your business.

Rooted in meaningful tradition

Proudly serving the State of Washington with cannabis testing, we’re the first tribally affiliated cannabis testing lab in the U.S.

Our tribally-sanctioned lab came about in part to ensure safe medical marijuana for cancer patients within the Puyallup Tribe itself, which is why our lab is located within the tribe's cancer center. Known for being “a generous people,” the Puyallup tribe also sees our cannabis lab as an opportunity to support a more natural way of managing pain and a way to promote safety within Washington's emerging cannabis industry.
