Federal drug agents say Interstate 25 remains a primary route for cartel-linked fentanyl trafficking through Wyoming, even as the state posts a significant drop in fentanyl overdose deaths compared with last year.

Fentanyl Seizures Already Exceed Last Year’s Total

Speaking in Cheyenne, U.S. Attorney Darin Smith and Drug Enforcement Administration officials said Wyoming has already seized nearly 6,000 fentanyl pills so far this year, surpassing the roughly 5,500 pills confiscated during all of 2025.

DEA Rocky Mountain Field Division Special Agent in Charge David Olesky said I-25, which connects Cheyenne, Casper, and Sheridan, remains a key transportation route for cartel-led trafficking organizations moving fentanyl, methamphetamine, cocaine and heroin through the state.

Federal officials said nearly all illicit fentanyl entering the country is manufactured by Mexico’s Sinaloa and Jalisco cartels using precursor chemicals shipped from China, then trafficked north through established smuggling corridors that reach states like Wyoming. Much of what circulates locally moves through distribution hubs in Denver and Salt Lake City before reaching Wyoming communities.

Overdose Deaths Are Down, but Risk Remains

Even with more fentanyl moving through the state, Wyoming recorded 54 opioid-involved fentanyl overdose deaths last year, down from 84 the year before, a decline of about 35 percent.

DEA laboratory testing now shows roughly three in every ten counterfeit pills seized nationwide contain a potentially lethal dose of fentanyl, down from about seven in ten in previous years.

Olesky cautioned that the improving trend does not mean people can let their guard down. “My number one advice to all is: don’t take a pill that doesn’t come directly from a licensed pharmacy and based on a prescription from your doctor,” he said.

Smith said Operation Take Back America has strengthened cooperation between local, state, and federal agencies to identify and prosecute drug traffickers operating in Wyoming, and that prosecutors intend to use every available resource to hold traffickers accountable, whether they are using the state’s highways, the mail, or stash houses to move narcotics.

Understanding Fentanyl and Naloxone

Fentanyl is a synthetic opioid up to 50 times stronger than heroin, and even a small miscalculation in dosage can cause a fatal overdose. Counterfeit pills made to look like prescription opioids or other drugs frequently contain fentanyl without the buyer’s knowledge, which is why federal officials continue to warn against taking any pill that did not come directly from a pharmacy with a valid prescription.

Naloxone, sold under brand names including Narcan, can reverse an opioid overdose within minutes when administered promptly and is available without a prescription in most states.

Fentanyl test strips, which can detect the presence of fentanyl in a substance before use, are another harm reduction tool that public health officials increasingly recommend alongside naloxone access.

Harm Reduction and Treatment for Opioid Addiction

Laramie County Sheriff Brian Kozak said his deputies have made 186 drug-related arrests so far this year and credited partnerships with the DEA and Wyoming Division of Criminal Investigation with helping connect people struggling with addiction to treatment programs when they are willing to seek help.

Whether someone is using fentanyl, heroin, or another opioid, medication-assisted treatment combined with peer support through Narcotics Anonymous meetings can significantly improve the odds of sustained recovery.
