Executions

Methods of Execution

Lethal injection is the most widely-used method of execution, but states still authorize other methods, including electrocution, gas chamber, hanging, and firing squad.

Overview

The primary means of execution in the U.S. have been hanging, electrocution, the gas chamber, firing squad, and lethal injection. The Supreme Court has never found a method of execution to be unconstitutional, though some methods have been declared unconstitutional by state courts. The predominance of lethal injection as the preferred means of execution in all states in the modern era may have put off any judgment by the Court regarding older methods.

Because of a resistance by drug manufacturers to provide the drugs typically used in lethal injections, some states now allow the use of alternative methods if lethal injection cannot be performed. Controversies surrounding the method to be used have delayed executions in many states, contributing to an overall decline in the use of the death penalty.
