lethal injection

This article is about the execution and euthanasia method. For the Ice Cube album, see Lethal Injection (album). Lethal injection involves injecting a person with fatal doses of poisonous drugs to cause death. The main applications are euthanasia and capital punishment (the latter of which is the focus of this article). As a method for capital punishment, lethal injection gained popularity in the twentieth century as form of execution meant to supplant methods – such as electrocution, hanging, firing squad, gas chamber, or decapitation – that were considered to be less humane. The humaneness of lethal injection has been debated. (See "Controversy," below.) It is now the most common form of execution in the United States: every American execution in 2005 was conducted by lethal injection.
