Dartmouth Police are now carrying the life-saving drug Narcan.

Det. Kyle Costa tells WBSM News the decision to carry the overdose-reversing nasal spray was made several months ago, with officers now having completed necessary training.

Costa says it's imperative for police to be outfitted with the drug. "For the most part, the police officers are always going to be the first ones on the scene when it comes to an overdose situation. And it's just going to give that person those vital seconds, minutes, if you will, that they may need in order to survive," says Costa.

A total of 15 kits have been purchased by the police department at $50 a piece. Each kit contains two doses.

Costa says in 2015, Dartmouth Police responded to one overdose a week on average.
