Substance Use Disorder (SUD) Treatment

Treatment and substance use disorders can be provided in different settings and may involve a team of providers such as counselors, psychiatrists, psychologists, nurses and physicians and peer support professionals. There is no one-size-fits all approach to substance use disorder treatment. Treatment should fit with the individual needs of the person asking for help – including you! Learn more about treatment options so you can make an informed choice about your treatment and recovery. To find a treatment provider near you, use the 2024 Interim Suffolk County Directory of Behavioral Health Services. The treatment providers in this guide are certified through the New York State Office of Addiction Services and Supports (OASAS).

Inpatient programs provide a safe and supportive setting for the evaluation, treatment, and rehabilitation of people with substance use disorders. These facilities offer 24-hour, 7-day a-week care that is supervised at all times by a medical professional. Inpatient services include intensive management of symptoms related to addiction and monitoring of the physical and mental conditions resulting from substance use.

Outpatient facilities provide clinical services for people with an addiction to substances and their families who have been impacted by their addiction. Outpatient services may be delivered at different levels of intensity according to the needs of the person. These services include counseling, education, and connections to community services.

Opioid Treatment Programs (OTPs) are OASAS-and-federally-certified sites where medication to treat opioid use disorder is administered. In addition to medications, these programs also offer numerous services and supports. These can include counseling, educational services, medical screening and care, mental health care, and referrals to social services. In most cases, people receiving services at an OTP are provided with long-term treatment, similar to management of chronic physical conditions. Pregnant women and people who use intravenous drugs are given priority admission to OASAS-certified treatment programs including OTPs.

An OTP is the only place where someone can get methadone to treat opioid use disorder. Other medications (buprenorphine and long-acting naltrexone injection) can be prescribed at other addiction treatment programs including clinics, as well as in other settings such as primary care and mental health clinics.

There are medicines to treat opioid use disorder. Medications for Opioid Use Disorder (MOUD) saves lives by curbing cravings and minimizing discomfort that comes from withdrawal. It also protects people from overdosing and reduces the chances of medical complications from opioid use, like infectious diseases. When used in combination with psychological and behavioral therapy and supports, MOUD decreases the likelihood of recurring use, increases engagement in treatment, and paves the way for recovery.

Residential services are designed for people who are in need of support in their recovery, and may not be able to participate in treatment without a 24-hour residential setting. Residential services are designed to develop or maintain recovery through a structured, substance-free setting, and can include group support, skills development related to independent living, and other services designed to promote recovery.
