It ain’t just the tane in that nasty tane-soup dabs that can mess you up. It’s the bug-spray too. A voluntary recall has begun in Denver by local dispensary Advanced Medical Alternatives after local officials found potentially hazardous levels of pesticides, as reported by The Cannabist.

133 individually packaged grams of concentrate were pulled for their high content of myclobutanil, a chemical banned by the state of Colorado for use on cannabis plants and labeled “slightly hazardous” by the World Health Organization and a “bad actor” by the Pesticide Action Network. Myclobutanil is the active ingredient in Eagle 20 brand pesticides.

As far its specific health effects, Toxipedia says burning it can create “toxic fumes” and prolonged exposure has been shown to affect the brain weight and reproductive capabilities of mice.

The particular strains that were recalled were AMA’s Grape Dawg Shatter, which was found to contain more than 154 parts per million of myclobutanil, and the Indica Blend Wax, which tested at 40 ppm of the chemical. The Environmental Protection Agency only permits .1 ppm in almonds and 9 pmm in leafy greens. Avermectin, another pesticide chemical banned by the state for cannabis use, was also discovered in AMA’s wax. The recalled concentrates had the batch numbers 75D-716, 62E-192 and 62E-169, and were sold at AMA’s Golden Triangle shop at 1269 N. Elati St. in Denver.

This is the eleventh pesticide-related recall so far in Colorado. It comes just weeks after two separate recalls of Gaia’s Garden’s edibles and a little over two months after Mahatma concentrates were recalled for its pesticide content.
