How Do Missouri Marijuana Testing Labs Submit and Report Test Results?

Within 7 days of collecting a marijuana sample, a testing facility shall file a report to the Missouri Department of Health and Senior Services. Laboratories must use the statewide track and trace system (Metrc) for this purpose. This report must include:

  • All results indicating whether the tested harvest or process lots passed or failed
  • The certificate of analysis provided to the licensee or third party
  • Photos of marijuana samples received at facilities

The submission of a test result report must coincide with or precede any notice of test results to the originating facility. Laboratory testing licensees must maintain all sampling and testing records for 5 years and provide them when requested.

Each licensed cannabis testing facility in Missouri has a set price for marijuana testing. Marijuana cultivators, manufacturers, and dispensaries can make enquiries on testing costs by visiting any of these cannabis testing laboratories in Missouri or contacting them by email or phone.

What Happens to Cannabis Products That Fail Lab Tests in Missouri?

Missouri requires cannabis products that fail testing to be placed on hold through the state’s track and trace system by the Division of Cannabis Regulation (DCR). These marijuana products can be reanalysed, remediated, or destroyed provided licensees notify the Department within 15 days of test failure. Marijuana products that passed mandatory testing may be retested through voluntary testing with a written approval from DCR.

Reanalysis and remediation are performed by another licensed laboratory in compliance with all rules for mandatory testing. A batch of marijuana that fails reanalysis may not be reanalysed but remediated one time. Cannabis products that fail mandatory or voluntary testing for heavy metals may not be remediated. Failed microbial and chemical residue screening may be remediated through hydrocarbon, carbon dioxide, or ethanol. A batch of marijuana that fails remediation may not be remediated but reanalysed one time.

A request for the remediation of a cannabis product in Missouri can be filed and submitted to the DCR by sending an email to complianceinspections@health.mo.gov. Licensees that proceed with remediating marijuana products before receiving written approval are subject to recalls, fines, notices of violation, and other disciplinary actions.
