Naloxone Administrations
Naloxone (commonly known as Narcan) is a life-saving medication used by police, EMTs, and hospitals to reverse opioid overdoses. Usage has risen steadily over the past decade, reflecting both greater availability and a persistent overdose crisis.
- Nassau County: ~2,400 administrations in most recent year
- Suffolk County: ~3,600 administrations in most recent year
- Combined: Nearly 6,000 lifesaving reversals annually
Treatment Admissions
According to state data, more than 12,000 Long Islanders entered treatment programs for opioid use disorder in the most recent year available. Suffolk County consistently records higher admission totals than Nassau, reflecting both population size and overdose burden.
