427 Drug & Alcohol Rehabs in Massachusetts

Sober Nation lists 435 treatment centers across Massachusetts, and where they cluster tells you something about where care is easiest to reach. Worcester and Boston lead with 32 listed centers each, followed by Springfield (19), Brockton (14), and a tie between Fall River and Pittsfield at 13 apiece. Holyoke (12), Roxbury and Jamaica Plain (11 each), and Lowell (10) round out the most-served communities. That spread reflects both population density and the state's long-standing investment in behavioral health infrastructure, though it also leaves rural areas comparatively thin.

Statewide, an estimated 20% of residents aged 12 or older — roughly one in five — meet criteria for a substance use disorder in a given year (SAMHSA NSDUH, 2022–2023), while the treatment gap is stark: about 77% of those who need substance use treatment do not receive it (SAMHSA NSDUH, 2022–2023). Overdose mortality, long driven by fentanyl, has fallen sharply of late — opioid-related overdose deaths dropped to 978 in 2025, the first time under 1,000 since 2013 and nearly 60% below the 2022 peak (Massachusetts Department of Public Health, 2025 preliminary data). Read together, these figures give context to the directory: listings show where help exists, not how many people still go without it.

The centers listed here vary widely in intensity, and knowing the difference helps you find the right entry point:

• Detox (19%) — medically supervised withdrawal; a short first step, not treatment on its own.
• Residential / inpatient (32%) — 24-hour structure for those who need to step away from daily triggers.
• Outpatient (68%) — the most common option, letting people live at home while attending scheduled treatment, from intensive day programs to weekly counseling.
• Medication-assisted treatment (54%) — medications like buprenorphine or naltrexone paired with therapy, especially for opioid use disorder.
• Aftercare (89%) — the most widely available level, supporting the fragile period after a formal program ends.

Most people move through several of these levels rather than just one; where you start depends on your substance, your health, and the support you have at home.

Cost is often the first worry, and in Massachusetts the coverage picture is comparatively strong. Among listed centers, 92% accept Medicaid — here administered as MassHealth — and 71% accept Medicare, meaning most facilities work with public insurance rather than cash-pay only. Because Massachusetts adopted the ACA's Medicaid expansion, many low-income adults qualify for MassHealth coverage that includes behavioral health and substance use treatment (KFF, Status of State Medicaid Expansion Decisions). Federal parity law — the Mental Health Parity and Addiction Equity Act — also requires most insurers to cover behavioral health comparably to physical health, a standard Massachusetts has long enforced through its own parity protections (CMS).

Still, the details vary: confirm what your specific plan approves, whether a facility is in-network, and what any copay or deductible looks like before you commit. For those who are uninsured or underinsured, the state's Bureau of Substance Addiction Services funds a network of publicly supported programs and provides access to treatment for the uninsured (Massachusetts DPH/BSAS). Ask each center directly what they accept — it's the fastest way to avoid a surprise bill.

If you're not sure where to begin, a few Massachusetts resources can point you toward vetted help. The state's designated authority for addiction services is the Bureau of Substance Addiction Services (BSAS), housed within the Massachusetts Department of Public Health, which licenses programs and funds public treatment. The Massachusetts Substance Use Helpline offers free, confidential referrals to state-funded and licensed programs — call or text “HOPE” to (800) 327-5050, 24/7. For co-occurring mental health needs, NAMI Massachusetts provides education, support groups, and family resources across the state. And if you or someone you love is in crisis, the 988 Suicide & Crisis Lifeline is available 24/7 by call or text for immediate, free support. These are starting points — reaching one of them is often the hardest and most important step.
