Nevada regulators launched an investigation into cannabis testing labs after tainted marijuana batches triggered two health advisories.
Department officials say marijuana products must be tested by state-licensed labs for potency, yeast, mold, pesticides, heavy metals and other toxins before being sold in dispensaries.
Officials say products from the same cultivators were tainted and discovered on shelves sold between July 10 and Aug. 28 at Acres Medical, The Apothecary Shoppe and Blackjack Collective.
Officials say mold exposure can lead to stuffy nose, wheezing and itchy eyes or skin.
