Minnesota Cannabis Testing Labs

Does Minnesota License Independent Cannabis Testing Labs?

The Minnesota Department of Health, through its Medical Cannabis Laboratory Approval Program, issues licenses to third-party testing laboratories located in the state to test medical cannabis.

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

Minnesota allows the remediation and retesting of cannabis that failed initial required testing. Dried raw cannabis samples that failed water activity and moisture content testing can be used to make medical marijuana concentrate or continue to be cured. If the dried raw cannabis fails microbiological contaminant or mycotoxin testing, the manufacturer can remediate it only once, then resubmit it for testing. If the sample submitted fails the contaminant testing after the process of remediation, the manufacturer can choose to either use the test batch to make cannabis concentrate in a way that the processing method effectively sterilizes the batch or dispose of them as medical cannabis waste.

A manufacturer can choose to remediate dried raw cannabis that failed heavy metal testing by using a processing method that effectively removes the heavy metals from the batch. The test batch must be disposed of as medical cannabis waste if it fails retesting.
