This site maps the treatment landscape across the state rather than running any program of its own. Our directory draws on SAMHSA FindTreatment.gov listings and covers 326 facilities in all, including 150 centers concentrated in the larger cities. Worcester, Boston and New Bedford each show eight listed sites, while Brockton, Springfield, Millbury, Falmouth, Cambridge, Westborough, Belmont and Haverhill hold three or more apiece.

Each listing tells you what a program offers, which substances and age groups it serves, what levels of care it runs, and which payment options it reports accepting, Medicaid among them. We describe what the record shows and leave the clinical questions to the people who assess in person, so you can walk into a first call already knowing which questions to ask.

Comparing centers in Massachusetts

Match the level of care to the need
Detox, residential programs and outpatient services do different jobs, and a clinician decides which fits. When you call a center in Massachusetts, then ask what it provides on site and where it refers when the answer is no.
Check withdrawal safety before anything else
Alcohol and benzodiazepine withdrawal can turn dangerous quickly, which is why medically supervised detox exists. For anyone who drinks heavily, medical staff should supervise detox at a Massachusetts center before rehab begins. SAMHSA defines detox as a stabilization step, not treatment on its own.
Ask what insurance and Medicaid cover
MassHealth and commercial plans vary in what they pay for inpatient or outpatient care. If you rely on Medicaid in Massachusetts, then confirm coverage with the facility and your plan before you commit. Ask what a sliding scale looks like if a gap remains.
Weigh location and dual diagnosis support
A program an hour away can work if the fit is right, but daily outpatient care usually needs to be close to home. When mental health and substance use overlap, then look for Massachusetts centers offering dual diagnosis treatment.

Common questions

How many treatment centers in Massachusetts are listed?
There are 326 facilities listed for Massachusetts on SAMHSA FindTreatment.gov as of late 2026, with 150 centers clustered in cities such as Worcester, Boston and New Bedford. The listings include detox, residential, outpatient and medication-assisted options. Counts change as programs open or close, so confirm details with a facility before making plans.
What is the difference between detox and rehab?
Detox is the brief medical stage that clears a substance and manages withdrawal, while rehab is the longer effort of counseling, building skills and ongoing support. SAMHSA views detox as a starting point, not full treatment. Since alcohol and benzodiazepine withdrawal can become medically serious, medical staff should supervise that first stage and advise on what comes next.
Does MassHealth cover inpatient rehab in Massachusetts?
MassHealth covers many substance use treatment services, though what it pays for hinges on the care level and your plan, so the answer differs from person to person. Ask the facility's billing office and your plan directly. Our helpline advisors can help you check coverage and availability, at no cost and with nothing expected from you.
What are the intensive residential treatment programs in Massachusetts?
Residential programs in Massachusetts range from short stabilization stays to longer structured care, and the 326 listed facilities include several levels. A clinician's assessment usually determines which intensity is appropriate. When you call, ask about length of stay, whether mental health care is included, and how aftercare is arranged.
Can you involuntarily commit someone in Massachusetts?
Massachusetts has a legal process, often called Section 35, that can require someone to enter treatment for a substance use disorder. It is used when a person poses a serious risk to themselves or others, and a court decides. Most admissions are voluntary. A family advocate or attorney can explain how the process works and when it might apply.
