Advanced Medical Alternatives Recalls Marijuana Products Due to Pesticide Residues

A Denver marijuana-infused manufacturing business, Advanced Medical Alternatives (AMA), is voluntarily recalling marijuana products due to the presence of potentially unsafe pesticide residues found in product samples.  The recall affects 133 units of 3 different products. The recalled products are marijuana concentrates that are typically used for smoking or vaporizing. 

Samples of marijuana concentrates sold by AMA had high levels of Myclobutanil and Avermectin, pesticides that the Colorado Department of Agriculture has determined cannot be used legally on marijuana in Colorado.

The Advanced Medical Alternatives concentrate products subject to the recall were sold only at their 1269 N. Elati St. location and bear the following product names and batch numbers on their labels:

Product Name:

Batch #:

Production Date:

Grape Dawg Shatter



Indica Blend Wax



Indica Blend Shatter




Consumers who have these recalled products should dispose of the products or return them to the store from which they were purchased. For more information about returns, Advanced Medical Alternatives 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.
