Nature’s Cure Recalls Marijuana Products Due to Possible Pesticide Residues

Recall includes Cultivation and Retail Facility (dba Colfax Pot Shop) 


A Denver marijuana cultivation facility, Nature’s Cure (dba Colfax Pot Shop), is voluntarily recalling marijuana products due to the presence of potentially unsafe pesticide residues in some product samples.  

Recalled products include marijuana plant material (flower, trim, shake) and hash concentrates (wax, shatter, budder, and hash oil).  Samples tested positive for residues of Spiromefesin, a pesticide that the Colorado Department of Agriculture has determined cannot be used legally on marijuana in Colorado.

In addition to operating the cultivation facility, Nature’s Cure has one retail location: Colfax Pot Shop, 1500 E. Colfax Ave., in Denver. Consumers who have purchased dried marijuana or concentrate products from this location before Oct. 6, 2015, should discard products labeled with cultivation facility #s of 403R-00035 or 403-00651 printed on the labels.

The following products are subject to the recall:

  • Dried medical marijuana with cultivation facility # 403-00651 printed on the exit label 
  • Dried recreational marijuana with cultivation facility # 403R-00035 printed on the exit label
  • Concentrates from The Lab, Craft 710, TC Labs, Lab 710, or Mahatma, with cultivation facility #s of 403R-00035 or 403-00651 printed on the label

Consumers who have these recalled products should dispose of the products or return them to the stores from which they were purchased. For more information about returns, the Colfax Pot Shop can be reached at

There have been no reports of illness. The possible health impact of consuming marijuana products with unapproved pesticide residues is unknown. Short- and long-term health impacts may exist depending on the specific product, duration, frequency, level of exposure, and route of ingestion.  Consumers with concerns about their personal health should contact their physician with related questions.

The Denver Department of Environmental Health (DEH) is partnering with state agencies to investigate this issue and oversee the recall process to remove potentially contaminated product from commerce. DEH conducts inspections of marijuana-infused product manufacturers and retail locations in Denver and investigates related complaints.  

Consumers with questions or concerns about recalled product or pesticide residues in marijuana products are encouraged to contact the product retailer and/or the DEH Public Health Inspections division at or 720-913-1311.
