LOUISVILLE, Ky. (WDRB) -- It was Jan. 7 when an LMPD officer stopped by a Dixie Highway gas station. 

While she was inside, someone told her two people had overdosed on drugs in the bathroom. 

Her body camera shows a man and woman on the floor and, even though the woman's face is blurred, you can tell she's turning blue. 

The officer runs to her car, grabs the overdose reversal drug Narcan, and gives both people a dose. 

"Nine times out of 10, police officers are first ones of the scene of an overdose," said LMPD Health and Safety Officer Erik Velten. 

That officer had started carrying Narcan less than a month before this happened. Fourth division officers were the first to get trained and start administering the drug. 

Soon all LMPD officers will know how to use it thanks to Velten. 

"Every single patrol beat in all of Louisville Metro will have two of these kits available at all times," he explained. 

Narcan is nothing new for some first responders. 

Metro EMS says it used the drug for suspected overdoses nearly 1,500 times in 2015. 

Police say the heroin bill passed by state lawmakers last year allows them to administer it now, too. 

But the drug is expensive. Velten says just to get things started it's around $45,000. He says the drug is about $40 a dose.  

But it's easy to use. Velten even showed us how it takes just a few steps to put the pieces together and use it as a nasal spray. 

"If we can help somebody who has made a bad decision and has made a mistake and we can help make a difference and save a life, then our officers are all for it," Velten told WDRB News. 

He says the fourth division has already made six saves, two of them from the Jan. 7 incident. 

In the video, you can see the man and woman wake up within about 10 minutes of getting the Narcan. 

Police expect to save many more lives.  

Velten says by the end of next week, all divisions will have the kits. 

Police tell WDRB News officers will not charge the people they help.
