Gov. Chris Christie said a tour of a Monmouth County neonatal unit for infants born to mothers on drugs made him want to do more to help them.

The governor toured the neonatal intensive care unit on Tuesday at Jersey Shore University Medical Center as part of an annual "Season of Service" effort.

Christie visited five infants with perinatal addiction and said seeing them strengthened his resolve to do all he can.

He said it's important not to forget these "innocent victims of drug addiction."

The Health Department says New Jersey hospitals handle about 500 neonatal drug withdrawal cases annually. Fighting drug addiction has been a top issue for Gov. Christie, who expanded drug courts so first-time nonviolent offenders can get treatment instead of jail time.
