DOE - Cannabis Science Task Force Steering Committee

Washington State Department of Ecology (DOE) Logo

The Washington State Department of Ecology (DOE) Cannabis Science Task Force (CSTF) Steering Committee is the leadership committee affecting the transition of responsibility for cannabis testing lab accreditation from the Washington State Liquor and Cannabis Board (WSLCB) to the DOE. In the absence of federal guidance, the Committee is also helping bolster cannabis testing lab standards.


On Monday at 9am PT @ the Department of Ecology (DOE), the Cannabis Science Task Force (CSTF) Steering Committee convenes for its fifth public meeting.

  • The methodical transition of responsibility for accreditation of cannabis testing labs from the WSLCB to the DOE continues. The CSTF was charged to develop cannabis laboratory “standards or adapt appropriate science-based analytical methods, method validation protocols, performance criteria, proficiency testing, and homogenization procedures for testing cannabis and cannabis products.” The Cannabis Science Task Force’s leadership committee meets monthly to hear updates from two work groups and adopt recommendations which become formal positions of the CSTF.
  • Steering Committee members will meet the new DOE Proficiency Testing Chemist hired to lead the Proficiency Testing Work Group, a role DOE Senior Chemist and Project Manager Sara Sekerak had been filling in addition to serving as lead chemist for the CSTF and author of its reports.
  • Complexities introduced by the different clients serviced by cannabis testing laboratories, first discussed at the Committee’s second meeting in late September, continues to occupy time on the agenda.
