Watch: Police officer inhales fentanyl, partners save her with Narcan

A Florida police officer lost consciousness Wednesday after a possible exposure to fentanyl.

Footage released by the Tavares Police Department showed Officer Courtney Bannick struggling to remain conscious while her fellow officers administered Narcan.

Bannick reportedly discovered the narcotics while searching a passenger during a routine traffic stop, WFLA reported. She uncovered narcotics in a rolled up dollar bill but rerolled the currency after discovering the drugs. She was wearing gloves at the time and her fellow officers asserted that she practiced safe handling during the search.

"She just barely opened it and saw that it was narcotics. Closed it quickly," said police detective Courtney Sullivan. "Next thing you know, she was trying to speak on the radio and you could hear in the radio traffic almost like she was choking."

Bannick experienced difficulty breathing while transporting the passenger from whom she'd seized the drugs to jail. The narcotics are thought to be fentanyl, an extremely potent drug entering the U.S. in ever larger quantities through the southern border.

She is expected to make a full recovery.

Fentanyl trafficking has become an increasingly large portion of drug cartel operations, while border authorities have reported seizing record quantities of it near the Mexican border. In July alone, they seized fentanyl in quantities sufficient to be lethal for more than the entire U.S. population.
