The Michigan Marijuana Regulatory Agency (MRA) has issued a recall for many cannabis products in the state due to inaccurate and unreliable test results. 

Retailers must pull almost all products, except for inhalable cannabis concentrate products, tested by compliance facilities Viridis North, LLC and Viridis Laboratories LLC between Aug. 10 and Nov. 16. Cannabis inhalable products include:

Vape cartsLive resinDistillateAny other cannabis concentrate created through residual solvent extractions

All retail locations that have sold such products must display the MRA’s recall on the sales floor and ensure it is visible to all consumers for 30 days from the date the notice was issued.

Licensees that have products in their inventory that fit the criteria have the following options:

Destroy the product and provide proof of destruction to the product retested for the microbials compliance panel.Send the product back to the original licensee source so they can destroy or have the product retested as a larger batch. 

If a licensee opts out to send back or retest a product, they must “create new METRC packages with new METRC identification numbers prior to transferring or submitting the products for testing,” the notice states.

Additionally, consumers who have purchased a product that meets the criteria can return it to the location of purchase for proper disposal. Consumers who have experienced adverse reactions from consuming such products should report their symptoms to a physician and the MRA by email: or phone: 517-284-8599, the notice states.

According to the notice, the MRA is still investigating. For additional information and questions, contact MRA at
