Last week, the Colorado Department of Revenue (DOR), the Colorado Department of Agriculture (CDA) and the Colorado Department of Public Health and Environment (CDPHE) announced a health and safety advisory for a large number of cannabis products grown and produced by Tree of Wellness Inc., doing business as Tree of Wellness. The health and safety advisory, synonymous with a product recall, was issued due to the detection of off-label pesticides in cannabis grown by Tree of Wellness.

Tests found Myclobutanil present in batches going all the way back to May, 2017, with some contaminated batches as recent as late October.

According to the press release, the CDA confirmed the presence of Myclobutanil, a near-ubiquitous fungicide used in a wide range of agricultural practices. The chemical has been a thorn in the side of the cannabis industry for being used off-label, or inappropriately, on cultivating cannabis.

Here are the batch numbers included in the recall

Myclobutanil is the active ingredient in Eagle 20, a pesticide used frequently in other agricultural fields like grapes, apples and spinach. According to UC Davis professor and Steep Hill scientist Dr. Don Land, Myclobutanil becomes significantly more dangerous when heated, or smoked. That chemical reaction produces hydrogen cyanide, an extraordinarily toxic chemical. Because of this, and the lack of research on what happens when these chemicals are burned or heated, there is a growing public concern that cannabis laced with a chemical like Myclobutanil can cause adverse health reactions.

The public health and safety advisory says they detected Myclobutanil in cannabis flower, trim, concentrates, and infused-products from Tree of Wellness. The CDPHE and DOR recommend consumers that have the affected products return them to where they were purchased for proper disposal.

Consumers in Colorado should check their labels to see if their products fall under the recall. Look for the Medical Optional Premises Cultivation License 403-00664 and/or Medical Marijuana Center License 402-00443. The recall includes batches of 23 different strains grown by Tree of Wellness.

According to a press release issued on Friday, September 22nd, the Colorado Department of Public Health and Environment (CDPHE), along with the Colorado Department of Revenue (DOR) and the Colorado Department of Agriculture (CDA), issued a public health and safety advisory for cannabis products tainted with pesticide residue.

The advisory was issued after the detection of pesticide residues on retail cannabis plant material and products with cannabis grown by RK Enterprises LTD, doing business as Rocky Mountain Remedies. The CDA confirmed that they detected the pesticide, Avermectin, an insecticide with a relatively high acute toxicity.

When pesticides like this are not on the list approved for use in cannabis cultivation, it is considered an off-label use. According to the press release, some of the products affected include flower, trim, concentrates and infused-products.

Consumers are advised to look at the label of their products and check to see if it matches the license number 403R-00180 and harvest batch numbers r206goldenkush9.11.17 and m206larryog9.11.17. Consumers are told to either dispose of the product properly or bring it back to the retail store where they purchased it.
