Key findings
  • California has the best access — 0 centers per 100,000 people — followed by Texas (0) and Florida (0).
  • Wyoming has the fewest at 0 per 100,000 — a 0× gap versus the top state.
  • Several high-population states (Vermont, District of Columbia, Alaska) rank near the bottom per capita — large raw facility counts can still mean thin access.
  • Nationally there are about 0 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. California — 0 centers per 100k (0 facilities).
  • 2. Texas — 0 centers per 100k (0 facilities).
  • 3. Florida — 0 centers per 100k (0 facilities).
  • 4. New York — 0 centers per 100k (0 facilities).
  • 5. Pennsylvania — 0 centers per 100k (0 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.

  • Wyoming — 0 centers per 100k (0 facilities serving 587,618 residents).
  • Vermont — 0 centers per 100k (0 facilities serving 648,493 residents).
  • District of Columbia — 0 centers per 100k (0 facilities serving 702,250 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.

Methodology

Treatment center counts come from Peninsula's directory of 0 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.
