A traffic stop in northern Iowa turned into a near-death encounter for a police officer.

According to the Fort Dodge Police Department, an officer conducted a traffic stop on a female driver around 5 p.m. Sunday, March 3. During the encounter with the woman, the unnamed officer handled an unknown substance. Then, while transporting the subject to jail for Providing False Information and Driving on a Suspended License, the officer fell ill. He began to feel dizzy and lightheaded. He then called for help. When medics arrived at Fort Dodge's Law Enforcement Center, the officer was described as unresponsive and lethargic. The video shows medics helping the officer:

The officer received two doses of Narcan from the first responders on the scene and more during treatment at the hospital. He was released on Monday and is reportedly doing fine.

Fort Dodge Police believe the unknown substance was the powerful opioid, Fentanyl. Further testing is being done to confirm the substance. Fentanyl is 100 times more potent than morphine and 50 times as potent as heroin.

Fentanyl has become a threat across the nation and in Arizona, the numbers are absolutely staggering. Doug Coleman, Arizona Drug Enforcement Administration Special Agent in Charge, told AZ Family, "Four years ago, we seized zero fentanyl in Arizona. Last year, we seized enough Fentanyl to kill 75 to 80 million people." The amount of Fentanyl that can kill a person is even scarier. Coleman says it's just two milligrams... "It's literally like a grain of sand."
