The Montana Department of Justice and Billings Police Department are warning residents of Yellowstone County about the increased presence of the synthetic opioid carfentanil, which is approximately 100 times more potent than fentanyl. Authorities recently seized a large amount of drugs trafficked into the state that tested positive for carfentanil, a substance typically used to tranquilize elephants.

Why it matters

Carfentanil is an extremely dangerous substance that can be absorbed through the skin or accidentally inhaled, posing a serious threat to public health and safety. The spike in carfentanil seizures in the Billings area is concerning, as even small amounts can be fatal.

The details

In 2025, the Montana State Crime Lab analyzed 14 different drug seizures that tested positive for carfentanil, with 9 of those coming from agencies in Yellowstone County. The Bozeman and Great Falls Police Departments, along with Flathead Tribal Law Enforcement, requested the other 3 seizures be tested. Authorities warn that carfentanil can come in various forms, including powder, blotter paper, tablets, patches, and sprays, and can be absorbed through the skin or accidentally inhaled.

• In 2025, preliminary data shows the Montana State Crime Lab has analyzed 14 different seizures that have tested positive for carfentanil.
• In May and October 2025, MTDOJ and BPD warned citizens of other large carfentanil seizures.

What’s next

Authorities are urging residents to be vigilant and avoid taking any pills or substances that have not been prescribed by a doctor. They are also encouraging people to learn the signs of an opioid overdose and to keep naloxone, a medication that can reverse overdoses, on hand.
