Columbus, Ohio (AP) -- Ohio has become the first state to adopt a procedure for lethal injections that uses one drug, a method never before tried on U.S. Inmates.
The state filed papers Friday in U.S. District Court saying it has decided to switch from a three-drug cocktail to a single injection of thiopental sodium into a vein.
A muscle injection will be available as a backup.
The decision comes two months after an Ohio death row inmate walked away from an unsuccessful execution and subsequent executions were put on hold.
Several states have faced similar challenges, but Ohio is the first to drop the three-drug approach in favor of one dose.
The death penalty information center says it's never been attempted on humans.
