Facilities: SAMHSA FindTreatment.gov, every Ohio listing that reports substance use treatment or detox, snapshot November 5, 2026. County centers: U.S. Census Bureau 2024 Gazetteer. Population: Census 2024 estimates. A facility is placed in a county by its ZIP code (Census ZCTA to county file). Distances are great-circle miles from the county's internal point to the facility's listed coordinates; listings without coordinates in SAMHSA are placed by the Census Geocoder from their address, or at their ZIP code center when no street is published. Certified opioid treatment programs (OTP) count as MAT. Data can be reused with a link to this page.
