(Metro PD)

Metro Police said detectives intercepted a tranquilizer used to cut heroin that was mailed from Florida.

Police said the package contained carfentanil, which is a legal and used as an elephant tranquilizer.

Detectives took the package out of circulation in Nashville to execute a search warrant. Metro Police said the found a packet inside with 140 mg of carfentanil, enough for thousands of lethal human doses. Carfentanil is 10,000 times more potent than morphine and is commonly illegally used as a cutting agent in heroin.

Police said the tranquilizer is a respiratory system depressant and responsible for numerous overdose deaths throughout the United States.

This is the first time MNPD narcotics detectives have intercepted a packet of carfentanil. Police said false information about the sender and recipient is making it difficult to identify the people involved.
