Addiction Treatment in Mercer County, NJ

Addiction Treatment Across Mercer County

New Horizons Addiction Center is located at 18 S Broad St in Trenton — in the center of Mercer County and accessible from all 13 municipalities in the county. We serve patients from Hamilton Township, Ewing, Lawrence, Princeton, West Windsor, East Windsor, Robbinsville, Hopewell, Hightstown, and surrounding areas. Our inpatient program is designed to serve the full Mercer County patient profile: the college-town professional from Princeton, the working family from Hamilton, the first responder from Lawrence, and the resident from Trenton's neighborhoods who needs to get distance from the environment driving their use.

The Mercer County Drug Landscape

Alcohol and heroin/opioids each account for approximately 34–35% of Mercer County treatment admissions, with cocaine a distant third at 11%. The opioid supply across the county — including in suburban municipalities — is now dominated by illicitly manufactured fentanyl, often mixed with xylazine, a veterinary sedative that cannot be reversed by naloxone. Mercer County's age-adjusted overdose death rate of 33.3 per 100,000 reflects the severity of this public health challenge. Source: NJDHS NJSAMS 2024; Trenton Health Team.
