Addiction Treatment Access by State (2026)

We ranked all 50 states and Washington, D.C. by the number of substance use treatment centers per 100,000 residents — using our directory of 21,105 facilities and 2024 Census population data — to reveal where help is easy to reach and where the treatment deserts are.

Key findings
  • Alaska has the best access — 14.9 centers per 100,000 people — followed by Maine (13.2) and Vermont (12.8).
  • District of Columbia has the fewest at 2.3 per 100,000 — a 6.5× gap versus the top state.
  • Several high-population states (Texas, South Carolina, Florida) rank near the bottom per capita — large raw facility counts can still mean thin access.
  • Nationally there are about 6.2 centers per 100,000 residents, yet only ~1 in 4 of the 48.5 million Americans with a substance use disorder received treatment in 2023 (SAMHSA).

Best treatment access: top 5 states

On a per-capita basis, the states where treatment is easiest to reach are mostly smaller-population states where a moderate number of facilities serves comparatively few residents.

  • 1. Alaska — 14.9 centers per 100k (110 facilities).
  • 2. Maine — 13.2 centers per 100k (185 facilities).
  • 3. Vermont — 12.8 centers per 100k (83 facilities).
  • 4. Kentucky — 12.3 centers per 100k (563 facilities).
  • 5. Utah — 12.2 centers per 100k (429 facilities).

Treatment deserts: 5 states with the least access

These states have the fewest treatment centers relative to their populations. Notably, some are among the most populous in the country — high raw facility counts can mask thin per-capita access and long travel distances to care.

  • District of Columbia — 2.3 centers per 100k (16 facilities serving 702,250 residents).
  • Texas — 2.9 centers per 100k (920 facilities serving 31,290,831 residents).
  • South Carolina — 3.8 centers per 100k (206 facilities serving 5,478,831 residents).
  • Florida — 3.8 centers per 100k (898 facilities serving 23,372,215 residents).
  • Alabama — 4 centers per 100k (207 facilities serving 5,157,699 residents).

What this means for finding treatment

Per-capita access is only part of the picture — what matters most is finding the right care near you. Even in lower-access states, options exist across detox, inpatient, and outpatient care, and telehealth has widened access further. If cost is your concern, see how much rehab costs in 2026 and our cost-by-state guide; if you're weighing programs, read how to choose a rehab center. For a city-level view, see our companion study, addiction treatment deserts: the biggest U.S. cities ranked.

Methodology

Treatment center counts come from RehabHive's directory of 21,105 U.S. substance use treatment facilities (sourced from SAMHSA's treatment locator and verified listings), as of 2026. Population figures are 2024 U.S. Census Bureau state estimates. Centers per 100,000 = (facilities ÷ population) × 100,000. Counts reflect listed facilities and may differ from other facility surveys; per-capita figures indicate relative access, not treatment quality or capacity. Treatment-gap context is from SAMHSA's 2023 National Survey on Drug Use and Health.

Frequently asked questions

Which state has the most addiction treatment centers per capita?+

Alaska leads with 14.9 centers per 100,000 residents, followed by Maine and Vermont. Smaller-population states tend to rank highest per capita.

Which states have the fewest treatment centers per capita?+

District of Columbia has the fewest at 2.3 per 100,000, followed by Texas and South Carolina. Several large states rank low despite high total facility counts.

How many addiction treatment centers are in the U.S.?+

RehabHive's directory lists 21,105 facilities across the 50 states and D.C. — about 6.2 per 100,000 residents nationally.

What is the addiction treatment gap?+

About 48.5 million Americans had a substance use disorder in 2023, but only roughly 1 in 4 received treatment (SAMHSA NSDUH). Thin per-capita access in some states contributes to this gap.
