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.
Authorized Methods
NOTE: [Brackets] around a state indicate that the state authorizes the listed method as an alternative method if other methods are found to be unconstitutional or are unavailable/impractical. Click on the state to obtain specific information about the methods authorized.
Method | # of executions by method since 1976 | # of states authorizing method | Jurisdictions that Authorize |
---|---|---|---|

To find the drug protocols used by states, see State-by-State Lethal Injection. |
Electrocution | 163 | 8 states (in South Carolina, electrocution is the default method; the other 7 have lethal injection as default method). | [Alabama], [Arkansas], Florida, Kentucky, [Louisiana], [Mississippi], [Oklahoma], South Carolina, [Tennessee] The supreme courts of Georgia (2001) and Nebraska (2008) have ruled that the use of the electric chair violates their state constitutional prohibitions against cruel and unusual punishment. Virginia had authorized the electric chair as a method of execution in some cases, but it repealed the death penalty in March 2021. |
Lethal Gas | 13 | 8 states (all have lethal injection as default method) | [Alabama], Arizona, California, [Louisiana], [Mississippi], Missouri, [Oklahoma], [Wyoming] Four states (Alabama, Louisiana, Mississippi, and Oklahoma) specifically authorize execution by nitrogen hypoxia, though only Alabama has issued a protocol for its use. Alabama is the only state that has performed an execution by nitrogen hypoxia. The other states listed authorize “lethal gas,” but do not specify what type of gas would be used. |
Firing Squad | 3 | 5 states (in South Carolina, electrocution is the default method; the other states have lethal injection as primary method) | [Mississippi], [Oklahoma], [Utah], [South Carolina], [Idaho] |
^Both Florida and Tennessee explicitly authorize lethal injection and electrocution, but state that, if those methods are found unconstitutional, prisoners may be executed by any constitutional method of execution.
