Lab Resources

The CCRS Lab Upload Guide details the process and information needed to successfully upload cannabis reporting data for labs.

Important Note

Each lab is expected to provide a PDF with any testing results that were uploaded to CCRS between 12/1/2024 and 1/15/2025 to COA@lcb.wa.gov. After 1/15/2025, the only COA that should be emailed are the new allowed cannabinoids, as those additions will be added to CCRS in a 2025 update.

Retesting Requirements

This page is for licensees who would like to know if they can retest a product that has failed at least one of the tests conducted by a certified laboratory. 

The licensee will need LCB approval received via reply to a retest request email. 

The LCB approval email can then be forwarded by the licensee to the laboratory conducting the retest.

If the failed product result is within the criteria for retesting, please:

  1. Send an email to lcbchemist@lcb.wa.gov containing ‘Retest Request’ in the title.
  2. Attach the Certificate of Analysis showing the failed test and result.
  3. Include the trade name, license number, inventory number, and the name of the test being requested.
