Colorado issues public health advisory after pesticide found on certain marijuana products

The Colorado Department of Public Health and Environment on Thursday warned that marijuana products from a local retailer could potentially contain harmful chemicals, calling the products a threat to public safety.

State health departments issued an immediate health and safety advisory on medical and retail marijuana cultivated by MMJ America Uptown, the department of revenue said in a news release.

The advisory cited “potentially unsafe pesticide residue” on marijuana flower, trim, concentrates and infused-products.

“Consumers who have these affected products in their possession should return them to the medical center or retail store from which they were purchased so they can be properly disposed of,” the release said.

The Department of Agriculture confirmed the presence of Diuron, an unapproved pesticide, on the marijuana products.

Affected marijuana has a label affixed to the container that indicates the license number. Consumers are advised to look for the following harvest batch numbers:

Medical Optional Premises Cultivation License 403-00426 and/or Medical Marijuana Center License 402-00288


Retail Marijuana Cultivation License 403R-00023
