State by State Lethal Injection

OVERVIEW

Almost all the states use a 3-drug combination for lethal injections: an anesthetic (either pentobarbital or sodium thiopental), pancuronium bromide (a paralytic agent, also called Pavulon), and potassium chloride (stops the heart and causes death). Pentobarbital in injectable form may only be available from Lundbeck Inc., a Danish company that has said it opposes the drug's use in executions (NY Times, 1/22/11; AP 1/26/11). The form of pentobarbital used in executions is also used for assisted suicides in Oregon and Washington.

Three states have used a single-drug method for executions--a lethal dose of an anesthetic (Arizona, Ohio, Washington). Three other states allow for one-drug executions in their lethal injection protocols, but have not carried out a one-drug execution (Idaho, Missouri, South Dakota).

In federal executions, the method is determined by the state in which the sentencing took place. All 3 of the federal executions in the modern era have been by lethal injection carried out in a federal facility in Indiana. Apparently the same 3-drug combination is used, though prison officials did not reveal the exact ingredients. (See Washington Post, Dec. 5, 2000). The U.S. Military has not carried out any executions since reinstatement. It plans to use lethal injection.

Twelve states have used pentobarbital in executions: Alabama, Arizona, Delaware, Florida, Georgia, Idaho, Mississippi, Ohio, Oklahoma, South Carolina, Texas, Virginia.

Three additional states plan to use pentobarbital: Louisiana, Montana, South Dakota.

One state (Missouri) plans to use propofol.
