Drug & alcohol rehab centers in Boston, MA

Every facility on Addictions.com is reviewed against a consistent set of quality and transparency signals before it appears in our Boston directory. We prioritize programs that hold current state licensure through the Massachusetts Bureau of Substance Addiction Services (BSAS) and independent accreditation from The Joint Commission or CARF, since these credentials reflect outside verification of clinical standards.

Our listings also weigh the range of care a program offers, the levels of care available on site, accepted forms of payment and whether the facility provides evidence-based services such as medically supervised detox and medication-assisted treatment. We use publicly available data, information reported by facilities and direct verification where possible. Rankings are never influenced by payment. When details cannot be confirmed, we note the gap rather than fill it, so families comparing options in Boston can make decisions based on verified information.

Boston, the seat of Suffolk County and the largest city in Massachusetts, anchors a metropolitan region of roughly 4.9 million people and holds one of the densest concentrations of addiction treatment in New England. Our directory tracks 52 rehab facilities in and around the city, spanning medical detox, residential care and outpatient services. Families comparing options across the wider region can also browse the full Massachusetts rehab directory for programs in nearby cities such as Cambridge, Quincy and Brockton.

The city's treatment landscape is shaped in large part by the Boston Public Health Commission (BPHC), whose Recovery Services Bureau operates a continuum of outreach, harm reduction and treatment navigation. Major teaching hospitals and health systems, including Boston Medical Center, add clinical depth that few cities can match, and BSAS licenses more than 500 treatment programs statewide, many of them clustered in the Boston area. This concentration means someone seeking care can often find several addiction treatment options within a short distance.

One notable local initiative is PAATHS (Providing Access to Addiction Treatment, Hope and Support), a BPHC-run one-stop program that offers walk-in assessments, phone support, and help arranging transportation to detox. It reflects Boston's broader approach of treating substance use as a public health issue and creating low-barrier entry points to care.

Boston's substance use picture has shifted meaningfully in recent years. After fatal opioid overdoses in the city peaked at 272 in 2023, the Boston Public Health Commission reported 169 deaths in 2024 and 120 in 2025, the lowest count in a decade. Fentanyl remains the dominant driver of overdose risk, and cocaine mixed with fentanyl has been a persistent concern, so many local programs emphasize opioid use disorder treatment alongside care for alcohol and stimulants. Officials caution that the illicit drug supply is volatile and that Black and Latinx residents continue to carry a disproportionate share of overdose deaths.

There is no single price for rehab in Boston. Cost depends on the level of care, the length of the program and the coverage a person brings to it. The figures below reflect statewide Massachusetts averages for uninsured, self-pay treatment and are best understood as a ceiling rather than what most people actually pay, since insurance, MassHealth and sliding-scale options reduce out-of-pocket costs substantially.

Boston sits at the higher end of the state's cost range. The overall cost of living in the city runs well above the national average, which raises the operating expenses of local facilities,  and private-pay residential rates in the Boston metro tend to reflect that. For most families, though, the more useful question is not the sticker price but how coverage applies. Verifying your rehab benefits before admission is the single most protective step, since cost surprises usually come from prior-authorization gaps rather than the treatment itself.

Across the 52 facilities in our Boston directory, programs accept a wide mix of payment types, and the absence of commercial insurance is a complication rather than a closed door. Massachusetts pairs strong public coverage through MassHealth with a state-funded safety net administered by BSAS, and state law requires commercial insurers to cover up to 14 days of acute addiction treatment without prior authorization. The counts below reflect how many local facilities accept each payment method.

Understanding which of these applies to your situation is the first step toward an affordable plan. The subsections below outline the most common paths Boston residents use to pay for care.

Boston's 52 facilities cover the full continuum of addiction care, including 29 medical detox programs, 32 inpatient rehabs and 42 outpatient clinics, along with strong dual-diagnosis and sober-living capacity. The cards below show how many local programs offer each level.

Medical detox is usually the first step for anyone with significant physical dependence. Under 24-hour supervision, clinical staff manage withdrawal safely, which matters especially for alcohol and opioids. Because detox stabilizes the body but does not treat the underlying disorder, it is followed by further care. Learn more about the medical detox process and what to expect.

Inpatient and residential rehab provides structured, live-in care with around-the-clock support and intensive therapy, well suited to moderate-to-severe substance use disorders or unstable home environments. Our guide to inpatient rehab covers program length and daily structure in more detail.

Outpatient rehab lets people live at home while attending scheduled treatment, and it ranges from standard weekly counseling to more intensive programming. It often serves as a step-down from residential care or an entry point for those with a stable support system. See our overview of outpatient rehab and intensive outpatient programs.

Dual-diagnosis programs treat substance use and co-occurring mental health conditions together, which is essential when untreated co-occurring depression or anxiety would otherwise undermine recovery. Sober living homes and other continuing care options support the transition back to independent life after a program ends.

Beyond standard levels of care, many Boston facilities tailor treatment to specific populations and substances. Given the city's large student population, aging residents and diverse communities, these specialty tracks help match care to people who need it.

The 47 alcohol-focused programs address the region's persistent drinking problem, where alcohol remains the leading substance in admissions to state-licensed treatment; our guide to alcohol use disorder explains the health risks and treatment approaches. The 38 opioid programs reflect the continued weight of the fentanyl crisis, with care for opioid use disorder frequently paired with medication-assisted treatment. Boston's dense concentration of colleges makes the 43 young adult programs especially relevant, and several coordinate with campus health services around young adult and college student substance use. The 10 LGBTQ+ friendly programs offer LGBTQ+ affirming addiction care, and the 5 veterans programs connect service members to specialized military and VA care.

Boston has one of the most developed public and nonprofit support networks in the country for people who use drugs or are seeking treatment. The resources below are free or low-cost and can help you find care, reduce overdose risk or connect with immediate crisis support. Many are reachable by phone at any hour.

Boston's overdose numbers have fallen sharply over the past two years, one of the steepest declines of any major U.S. city, even as the illicit drug supply stays volatile and racial disparities persist. The figures below draw on the Boston Public Health Commission, the Massachusetts Department of Public Health and independent research on the region.

The decline has been especially pronounced among groups long hit hardest by the crisis: fatal overdoses among Black residents fell by an average of 65% across 2024 and 2025 compared with 2023. Even so, inequities remain stark. Black and Latinx residents make up roughly 37% of Boston's population but accounted for about 48% of overdose deaths in 2025, which is why the city continues to target prevention resources toward the most affected neighborhoods, including Roxbury and Dorchester.

Alcohol remains a heavy and sometimes overlooked burden in the region. Statewide, excessive alcohol use causes an average of about 2,760 deaths a year, and in the Greater Boston area alcohol is the leading substance in admissions to state-licensed treatment programs, accounting for over half of substance-related cases. Roughly one in four Massachusetts adults reports binge drinking in a given month, a rate above the national average, underscoring why the city's substance use picture extends well beyond opioids. Fentanyl mixed with cocaine has been a growing driver of overdose deaths, so much of Boston's opioid response also addresses stimulant use.
