(Cleveland) -- The Cuyahoga County Medical Examiner has issued a public health warning after seeing a large increase of seized carfentanil. Carfentanil is a very deadly opioid and Doctor Thomas Gilson says anyone who uses illicit drugs needs to know it's showing up in the region. It is usually used as a sedative for large animals, and is extremely potent. At least 58 drug overdoses were recorded in the county last month.
