Colorado Regulator Issues Two New Warnings About Moldy Cannabis Products

State regulators in Colorado have issued two more health and safety notices after “potentially unsafe levels” of total yeast and mold and Aspergillus were found in certain pre-roll cigarettes and batches of cannabis flower.

The respective products were produced by two different companies, MJ Durango LLC (the pre-rolls) and Carrick-Harvest LLC (the flower).

In two safety notices, both published on March 20, the Colorado Department of Revenue and the Colorado Department of Public Health and Environment said that the levels of mold found in the products were “above the acceptable limits” of the state.

Through two investigations, the Department of Revenue identified that some of Durango’s pre-rolls were improperly submitted for testing while Carrick-Harvest’s flower batches underwent “a separate decontamination process compared to their corresponding Test Batches”, rendering the test results unreliable.

In response, MJ Durango worked with the state’s Marijuana Enforcement Division to issue a voluntary recall of its affected pre-rolls, which were sold between October 19, 2022, and February 2, 2023, at approximately 30 stores across the state.

Carrick-Harvest LLC hasn’t issued a similar recall, but the Department of Revenue has advised any consumers who have bought the company’s affected cannabis products to destroy or return them to the store they were purchased from.

Any consumers who experience adverse health effects from the products have been advised to seek medical attention immediately and report the event to the Marijuana Enforcement Division (MED) by submitting a MED Reporting Form.
