Colorado marijuana regulators on Friday announced a big recall of medicinal cannabis grown with unapproved pesticides. The marijuana in question was sold by a dispensary with storefronts in Boulder and Glendale.
The recall is one of a series in which Guardian, a pesticide that had been sold as "all natural," was found to contain concentrations of a substance banned for use on cannabis, report David Migoya and Ricardo Baca at .
Colorado in January had removed Guardian from its list of approved pesticides for use on marijuana.
More than 92 lots of cannabis, with each lot containing up to dozens of plants, produced by Life Flower Dispensary at its grow on Arapahoe Road in Boulder and sold at its storefront on Leetsdale Drive in Glendale are subject to the latest recall, according to the Colorado Marijuana Enforcement Division.
"We were using Guardian in late September and early October, and there are a couple of those plants still in flower," said Neal Bigelow, general manager at Life Flower. "That's exactly what we're going through."
Colorado regulators found the presence of abermectin, which isn't allowed for growing cannabis.
