The use of Narcan, the opioid overdose antidote, has nearly tripled in New Jersey since 2014. That's the year police officers and other first responders began carrying it. State Police figures show Narcan was administered more than 14-thousand times last year, compared to 51-hundred in 2014. The numbers show every county in the state, except Monmouth and Ocean, has seen a rise in Narcan use. In the two Shore counties, there's been a drop but State Police data doesn't explain why.
