A chemical tranquilizer 100 times more potent than fentanyl and 10,000 times stronger than morphine is rapidly spreading through the US drug supply, killing hundreds of unsuspecting users.

Carfentanil, a large-animal tranquilizer researched for years as a potentialchemical weapon, was identified 1,400 times in Drug Enforcement Administration (DEA) seizures in 2025, a nearly ten-fold increase from just 145 identifications in 2023 and only 54 in 2022.

The surge reported by the DEA has already turned deadly. In 2024, the most recent year with completeCDCdata, carfentanil contributed to 413 overdose deaths across 42 states and Washington,DC, nearly triple the previous year's count.

Theresurgence of carfentanilcan be linked to recent Chinese government restrictions on precursor chemicals used to make fentanyl, according to DEA intelligence.

With those precursors harder to obtain, Mexican trafficking cartels appear to be turning to carfentanil as a substitute or additive to boost the potency of a weaker, less pure version of fentanyl.

Unlike fentanyl, which has killed hundreds of thousands of Americans over the past decade, carfentanil has no legitimate human medical use. Veterinarians use it to tranquilize elephants, rhinos and bears.

Becausea lethal doseof carfentanil is smaller than a grain of salt, the drug's extreme potency renders standard overdose reversal measures dangerously inadequate.

While naloxone (Narcan) can revive someone overdosing on heroin or fentanyl when administered quickly, even multiple high doses may fail to reverse a carfentanil overdose.
