Drug & alcohol rehab centers in Cambridge, MA

Every listing on this page is drawn from our directory of licensed and accredited treatment providers in Cambridge and the Greater Boston area. We organize them in a way that helps you compare your options, including the level of care, the people who are served, and payment options, instead of giving preference to whoever paid the most.

Priority is given to providers with recognized third-party accreditation, including current Massachusetts licensure and clear information about their services. We also specify when a program offers medication-assisted treatment, specialized tracks or financial assistance, so you can factor that into your decision.

When a placement is sponsored, we label it as such. The listing's position in the directory is not a clinical endorsement. Importantly, you should always verify current services, availability and insurance acceptance directly with any facility before you enroll.

Home to Harvard and MIT, Cambridge is a city just across the Charles River from Boston in Middlesex County. The Massachusetts rehab directory lists 17 treatment providers in and around the city that are weighted toward inpatient and outpatient care and cover most addiction treatment options. 

Cambridge Health Alliance is the city's safety net, providing outpatient addiction services and medication-assisted treatment, alongside the Cambridge Public Health Department and Boston-area systems a short distance away. In addition, the free and around the clock Massachusetts Substance Use Helpline is the single statewide option that connects anyone to harm reduction, treatment and recovery.

Overdose data is tracked closely in Cambridge, with recent trends showing that both opioid overdoses and deaths fell sharply in 2024. Although the data is trending in a positive direction, opioid use disorder is driving most of the harm, as fentanyl, cocaine and xylazine are turning up in most fatal overdoses. For this reason, quick access to treatment and naloxone remains essential.

The cost for rehab in Cambridge varies and depends on a variety of factors such as the level of care required, length of treatment, whether the program is public or private and what services are covered by your insurance.   Outpatient counseling is the most affordable option, whereas medical detox and residential care cost more because they include around-the-clock supervision. Medication-assisted treatment falls somewhere in between.

Local figures align with Massachusetts averages. It's important to keep in mind that most people pay far less than the sticker price once insurance, MassHealth or a sliding fee scale is applied.

Again, most people do not pay these amounts out of pocket, because Massachusetts expanded Medicaid. This means that for qualifying members, MassHealth covers the full continuum of substance use care, often at little or no cost. In addition, the state funds free treatment for the uninsured through the Bureau of Substance Addiction Services.

Other options include Treatment scholarships and financial assistance that can help close the gap for private programs.

Most treatment centers listed for Cambridge accept self-payment and private insurance, and several also bill MassHealth or Medicare.
