Colorado recalls Artisanal Medicinals pot over pesticide concerns

Regulators say tests found traces of three pesticides not approved for use on marijuana, spurring health advisory

Colorado regulators on Wednesday recalled 25 strains of medical marijuana produced and sold by Artisanal Medicinals in Denver over concerns they were grown with unapproved pesticides.

The recall, which the state calls a health advisory, is the second issued by the Colorado Marijuana Enforcement Division in three days and the seventh since its first was announced Feb. 17.

Artisanal is the operating name of CNW LLC.

The advisory notes the marijuana tested positive for myclobutanil, avermectin and imidacloprid.

The company’s two owners could not be immediately reached.

Officials say the marijuana covered by the advisory includes growing dates dating to Jan. 26. Consumers who purchased the product should return it to the place of purchase to ensure it is disposed of properly.

It is unclear how large the recall is or how many actual products or plants are affected. Product labels will contain the business’s license number, 403-0039 or 402-00039.

The list of strains can be found on the state’s website.

The company’s website did not offer any information about the recall or that one had been declared.

Gov. John Hickenlooper in November declared that any marijuana grown with unapproved pesticides is a public health risk and should be destroyed.
