New Jersey runs its substance use system through the Division of Mental Health and Addiction Services (DMHAS), the state’s designated Single State Agency for substance use, which plans, funds, and monitors treatment across the state.
Facility licensing sits with the New Jersey Department of Health, and the state operates ReachNJ, a 24-hour line that connects any resident to help. Anyone choosing a detox center can start there or dial 1-844-ReachNJ at any hour.
New Jersey has invested heavily in access and harm reduction. The state expanded Medicaid, and NJ FamilyCare now covers the full continuum of care, from medically managed withdrawal to medication-assisted treatment.
Since 2022, New Jersey has also grown its network of authorized Harm Reduction Centers from seven to more than fifty, reaching all twenty-one counties, and launched Naloxone365 to distribute free naloxone at hundreds of pharmacies.
These efforts are showing results. Overdose deaths fell across all racial and ethnic groups for the first time in a decade, and preliminary counts dropped further in 2024.
Fentanyl still contaminates most of the illicit supply, which is why medically supervised detox matters. Admission usually begins with an assessment that assigns an American Society of Addiction Medicine (ASAM) level of care to match the setting to a person’s needs.
