Cannabis laboratories report

Accrediting labs is core work for us. We accredit nearly 500 drinking water labs throughout Washington and across the nation. Because we have expertise in lab accreditation, we were recently directed by the Legislature to research protocols and accreditation standards for cannabis testing laboratories.

Report to the Legislature

The 2018 – 2019 budget included a proviso that directed us to develop a report for the Legislature that provides recommendations for cannabis lab accreditation. We began this work in July 2018 and submitted the report to the Legislature in Feb. 2019. 

We researched appropriate protocols and accreditation standards to ensure that recommendations meet state certification requirements. Part of our research has included working closely with the Washington Liquor and Cannabis Board to understand the current process for a cannabis lab to become certified. Our report includes information on how we might become the official agency for state accreditation of cannabis labs.

Accreditation Report

Our legislative report on cannabis lab accreditation is now available. The report includes discussion of four proposed models ranked using the following criteria:

  1. Does the model provide a plan for comprehensive accreditation?
  2. Does the model provide essential technical assistance for both specific subjects and broad topics?

How can I get updates on the Legislative Cannabis Labs Accreditation project? Does the Cannabis Labs Accreditation Report set new standards for cannabis products?

About accreditation

Laboratory test results impact many areas of our daily lives — assurance of safe drinking water, food safety, health care, environmental monitoring, providing energy, mineral exploration, and various production processes. Government agencies and others rely on the competence of laboratories to deliver the results on which important decisions are made. Accreditation enhances public confidence in those test results and is a tool to show that labs are capable to producing accurate data.

We already administer an established environmental and drinking water laboratory accreditation program, where nearly 500 laboratories are currently accredited. We leveraged our experience in running a laboratory accreditation program to inform our recommendations.
