Drug Rehab by State: Find Licensed Treatment Centers in All 50 States
The United States operates over 14,000 state-licensed substance abuse treatment facilities, yet SAMHSA reports that only 10.3% of the 46.3 million Americans with a substance use disorder received any treatment in the past year (2023 National Survey on Drug Use and Health). This state-by-state directory helps you locate SAMHSA-listed, state-licensed rehab centers offering medically supervised detox, residential inpatient programs, intensive outpatient (IOP), partial hospitalization (PHP), and medication-assisted treatment (MAT) with buprenorphine, methadone, or naltrexone. Each state listing includes facility counts, program types, and ASAM level-of-care categories so you can match your clinical needs to the right treatment setting.

Why Location and State Licensing Matter in Addiction Recovery
State-level regulatory frameworks directly affect treatment quality, access, and cost. The 40 states that expanded Medicaid under the Affordable Care Act provide significantly broader coverage for substance use disorder (SUD) treatment — including MAT, residential stays beyond 30 days, and outpatient behavioral therapy. States also vary in their licensure requirements: some mandate CARF or Joint Commission accreditation, while others set minimum staffing ratios for clinical staff. ASAM guidelines recommend matching patients to treatment settings based on six clinical dimensions, including withdrawal potential, biomedical conditions, and recovery environment — making geographic choice a clinical decision, not just a personal preference.
What Each State Listing Includes
- SAMHSA-listed, state-licensed treatment facilities
- Medicaid, Medicare, TRICARE & private insurance acceptance
- CARF and Joint Commission accreditation status
- Specialty tracks: dual-diagnosis, veterans (VA), adolescents, LGBTQ+, pregnant women
- MAT availability (buprenorphine, methadone, naltrexone)
ASAM Levels of Care Available
- Level 0.5 — Early intervention and screening
- Level 1 — Outpatient (fewer than 9 hours/week)
- Level 2.1/2.5 — Intensive outpatient (IOP) and partial hospitalization (PHP)
- Level 3.1-3.7 — Residential inpatient (24-hour clinical care)
- Level 4 — Medically managed intensive inpatient detox
What You'll Find on This Page
This directory organizes 14,000+ SAMHSA-listed treatment facilities by state, with clinical and regulatory data to support informed decision-making:
- Compare all 50 states by licensed facility count, program types, and ASAM levels of care
- Identify states with Medicaid expansion for broader SUD treatment coverage
- Click any state to drill down into cities, accredited facilities, and specialty programs
- Evaluate whether local treatment or out-of-state care better matches your ASAM-assessed clinical needs
Pro tip: SAMHSA's 2023 data shows that states with Medicaid expansion have 25% more treatment admissions per capita — expanded insurance access directly increases treatment availability and reduces wait times.
