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.

GROTON, CT - MARCH 23: A box of the opioid antidote Naloxone, also known as Narcan, sits on display during a family addiction support group on March 23, 2016 in Groton, CT. The drug is used to revive people suffering from heroin overdose. The group Communities Speak Out organizes monthly meetings at a public library for family members to talk about how their loved ones' addiction affects them and to give each other emotional support. Communities nationwide are struggling with the unprecidented heroin and opioid pain pill epidemic. On March 15, the U.S. Centers for Disease Control (CDC), announced guidelines for doctors to reduce the amount of opioid painkillers prescribed nationwide, in an effort to curb the epidemic. The CDC estimates that most new heroin addicts first became hooked on prescription pain medication before graduating to heroin, which is stronger and cheaper. (Photo by John Moore/Getty Images)

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.
