Treatment Facilities by City

Nationwide coverage across all 50 states and DC. Top cities with the most substance use and mental health treatment facilities. Browse by city or browse by state to see all cities.

How city-level treatment infrastructure varies across the US

Treatment-facility density is not uniform across US cities — it tracks population, Medicaid expansion status, state behavioral-health funding, and local opioid-crisis prevalence. The 12 cities listed on this page collectively host the largest share of SAMHSA-registered substance use and mental health facilities, but density per capita matters more than raw counts. A small city with 15 facilities and 80,000 residents often has more accessible care than a metro with 200 facilities and 5 million residents.

Each city detail page includes the same data dimensions: total facility count, Medication-Assisted Treatment (MAT) availability, detox programs, residential beds, telehealth options, Medicaid acceptance, sliding-fee scale availability, and the full SAMHSA N-SUMHSS record for each provider. Use the search and filter controls on individual city pages to narrow by service type, payment method, or population served (adolescents, veterans, pregnant women, criminal-justice referrals).

Why some cities are not listed here

The list below ranks cities by total facility count from the SAMHSA N-SUMHSS 2024 survey. Cities with fewer than 76 reported facilities are surfaced via the state-level browse pages rather than this top-12 index — there are simply too many small towns with one or two facilities to list nationally. If you are searching for treatment in a smaller community, browse by state first, then drill down into the relevant state page to find county-level and city-level coverage.

What the SAMHSA N-SUMHSS captures (and what it does not)

The N-SUMHSS is an annual census-style survey, not a real-time directory. Facilities self-report their service mix, payment acceptance, hours of operation, and population specializations. Wait times, bed availability, current insurance contracts, and staff credentials are best confirmed on a direct intake call — these change between survey cycles. The survey does not collect clinical-outcome data, quality scores, or accreditation status beyond what facilities themselves report. We present the data factually and let visitors make their own assessments.

Crisis resources before you keep reading

If you or someone you know is in an active substance-use crisis or mental-health emergency, call the SAMHSA National Helpline at 1-800-662-4357 (free, confidential, 24/7) or the 988 Suicide & Crisis Lifeline before navigating treatment options. This directory is a starting screen for non-emergency research; it is not a substitute for licensed clinical guidance.
