Paterson is the Passaic County seat, so county treatment data provide the most consistent official local measure. New Jersey DMHAS recorded 4,094 Passaic County resident treatment admissions in 2024. These are admissions, not unique residents, and repeat episodes may be counted.
Heroin was the primary drug in 1,436 admissions, alcohol in 1,400, marijuana or synthetic cannabinoids in 496, cocaine in 370, and other opiates in 232. New Jersey substance-use statistics place those county treatment episodes within statewide patterns.
The same report recorded 915 outpatient admissions, 838 intensive outpatient admissions, 772 residential detox admissions, and 37 Partial Hospitalization admissions. Detox manages acute withdrawal, inpatient care supplies overnight supervision, Partial Care provides intensive daytime treatment, and IOP or outpatient care supports clinically stable adults living at home.
The Passaic County Division of Mental Health and Addiction Services, at 401 Grand Street in Paterson, funds prevention, early intervention, treatment, recovery support, crisis intervention, and the county IDRC; its service-information number is 973-881-2834. ReachNJ provides statewide treatment navigation at 1-844-732-2465.
Detoxification, hospital care, residential rehabilitation, and outpatient programs solve different clinical problems. Inpatient and outpatient rehabilitation differ by residence, supervision, medical risk, and weekly treatment structure.
