Advanced Medical Alternatives yanks pot concentrates in state’s 11th recall

Denver marijuana shop Advanced Medical Alternatives is recalling some pot concentrates with extremely high levels of pesticides banned for use on cannabis plants in Colorado

Denver marijuana business Advanced Medical Alternatives is voluntarily recalling 133 individually packaged grams of cannabis concentrates because they contain potentially dangerous pesticides banned for use on pot plants in Colorado.

Some of AMA’s marijuana concentrates tested for extremely high levels of the banned pesticides, according to city officials; The Grape Dawg Shatter tested for more than 154 parts per million of myclobutanil, and the company’s Indica Blend Wax tested for 40 ppm of the same chemical, which is the active ingredient in Eagle 20 brand pesticides and is considered “slightly hazardous” by the World Health Organization and a “bad actor” by the Pesticide Action Network.

Comparatively, the Environmental Protection Agency’s allowed myclobutanil residues on traditional crops are set between .1 ppm (almonds) and 9 ppm (leafy greens). Pesticide chemical avermectin, also banned for use on marijuana in Colorado, also showed up in AMA’s marijuana concentrates.

Denver’s Department of Environmental Health on Thursday announced the AMA recall — the department’s 11th pesticide-related recall of cannabis products in three months. This most recent recall involves three AMA-branded concentrates, labeled with batch numbers 75D-716, 62E-192 and 62E-169 — sold only at the company’s Golden Triangle shop at 1269 N. Elati St. in Denver.

Calls and emails to AMA were not immediately returned on Thursday.

The investigation into AMA’s concentrates was spurred by a previous recall involving Colorado edibles company Gaia’s Garden, city officials said. Gaia’s Garden was the subject of two recalls within 15 days of each other.

Customers who purchased the tainted AMA concentrates should dispose of them, return them to the shop or email info@amadispensary.com.
