Ohio reports alarming uptick in deadly synthetic opioids, including carfentanil
A dangerous drug believed to be about 100 times more potent than fentanyl is being seized at an increased rate in Ohio.
According to Ohio Attorney General Dave Yost, the Ohio Bureau of Criminal Investigation is reporting a continued rise in drug seizures involving carfentanil and other deadly synthetic opioids.
So far in 2025, BCI forensic scientists have identified carfentanil in 199 items that were submitted to the bureau’s laboratory for testing.
A deadly synthetic opioid, carfentanil is about 100 times more potent than fentanyl and about 10,000 times more potent than morphine, according to Yost.
Carfentanil is not approved for human use and has been used by veterinarians to anesthetize elephants and other large animals.
“The amateur chemists who create these deadly drug combinations don’t care if you live or die,” Yost said. “Here’s the deal: If you take drugs that weren’t prescribed by your doctor, you risk lethal exposure to synthetic opioids.”
Carfentanil can be found alone or in complex mixtures with fentanyl, xylazine and other opioids. It can come as a powder, liquid or be compressed into solid materials and tablets.
Additionally, Ohio BCI recently identified a new opioid compound in Ohio, N-propionitrile chlorphine, also known as cychlorphine. It is a rare synthetic opioid with effects similar to fentanyl.
The drug was seized at the scene of an overdose in Fairfield.
