Attorneys for death row inmates challenging Ohio’s use of midazolam say it doesn’t render inmates fully unconscious, leading to an unconstitutionally high risk of harm.
The state argues that the massive dose planned in Ohio of 500 milligrams — 10 times what it used on McGuire — is more than enough to ensure inmates don’t feel pain. The state also says the U.S. Supreme Court permitted the drug’s use in a 2015 ruling out of Oklahoma.
