What is Carfentanil?
Carfentanil is an extremely potent fentanyl analog (synthetic opioid). Designed in 1974, carfentanil was previously
used exclusively for veterinary use with large animals and is not approved for use in humans, as it has been
shown to be 100 times more potent than fentanyl in animal studies. Other fentanyl-related compounds have been
reported by the DEA National Forensic Laboratory Information System (NFLIS), which systematically collects drug
identification results from drug cases submitted for analysis to forensic laboratories (referred to as drug
submissions). [2]
