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.
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.
