Gov. Chris Christie says that there have been nearly 11,000 uses of medication to treat drug overdose patients in emergency situations in New Jersey since 2014.

Christie on Monday discussed a program that allows first responders to carry and administer Narcan after the Republican signed a waiver authorizing EMTs and EMT-trained police officers to carry and administer the drug.

Narcan counteracts the effects of heroin and other opioid drugs. It is administered through a nasal spray or injection into a muscle.

Christie attended a Narcan training session and then participated in a roundtable discussion at Hoboken University Medical Center.

More than 1,400 people have been trained to administer Narcan since the Opioid Overdose Prevention Program was launched in November.
