Sober Nation lists 365 treatment centers across New Jersey, and they cluster where the population does. Newark leads with 17 listed centers, followed by Trenton with 11, then New Brunswick, Toms River, Paramus, and Flemington with 8 apiece. Freehold, Camden, and Paterson each list 7, and Cherry Hill lists 6. That distribution traces the state's population geography: the dense Newark–Paterson north, the Trenton–Camden corridor along the Philadelphia border, and shore communities like Toms River that were hit especially hard during the peak overdose years.
Statewide, about 15 percent (14.9%) of New Jersey residents aged 12 or older meet criteria for a substance use disorder in a given year, and roughly three-quarters — about 77% — of those who need substance use treatment do not receive it, the persistent gap between the people who need care and the people who actually get it (SAMHSA, 2022–2023 National Survey on Drug Use and Health). Overdose deaths — the majority of which now involve illicit fentanyl rather than prescription pills — declined for the first time in years in 2023, falling to 2,816 from 3,171 in 2022, with a further decrease reported in 2024 (New Jersey Department of Health). The 365 programs listed here span that full continuum of need, from medically supervised withdrawal to long-term outpatient counseling, which is why the raw count matters less than finding the right level of care for your situation.
