Cannabis Laboratory Validation Approval Status

Cannabis Laboratories were required to submit validation study data for four testing parameters to ensure they came into compliance with the standards set forth in WAC 16-309 and WAC 16-310 by the deadline, January 1st 2025. Below is the status of each laboratories submissions. "Approved" means that a laboratory has submitted satisfactory data that has demonstrated their compliance with the updated standard. "Under Review" means that the laboratory submitted data for a given parameter, but still needs to correct some components to come into compliance. "Not Accredited" means that the laboratory was not accredited for that parameter and does not plan to be at this time.  Laboratories that do not bring parameters into "approved" status may be at risk for suspension. This status table has been updated as of April 2, 2025.
