Across Colorado, Utah, Wyoming and Montana, just under 3.2 million illicit fentanyl pills and 92.5 kilograms of fentanyl powder were seized between the start of 2026 and now, according to the Rocky Mountain division of the Drug Enforcement Administration.

Those amounts of seizures are “disproportionately higher” than amounts seized in other parts of the country, the DEA said.

David Olesky, special agent in charge of the DEA’s Rocky Mountain division, said in a news release that while fentanyl powder is prevalent across the whole country, the Interstate 25 and Interstate 70 corridors are becoming “fentanyl pill superhighways.”

“Our division continues to seize an abundance of fentanyl pills disproportionately higher than the amounts seized in other parts of the country,” he said.

Fentanyl remains a massive threat to the safety of the American public and to the people in the four-state region, Olesky said.

According to the DEA, the amount of pills and powder seized is enough to constitute millions of potentially fatal doses. Just two milligrams is enough to cause an overdose.

Colorado remains the state in the division with the majority of seizures, with 2.5 million so far in 2026. Utah ranked second with just over 600,000, while Montana saw 14,500 pills seized and Wyoming 5,500.

The number of pill seizures in the division went up last year, from 5 million in 2024 to 8.7 million in 2025. If the numbers remain steady, 2026 will see a slight dip in the number of total seizures by the end of the year.

Nationally in 2026, the DEA has seized 18.7 million pills and 7,900 pounds of fentanyl powder.
