   Lethal injection (Wikipedia)

   WikipediaPublished Oct 10, 2026Checked Oct 11, 2026

   “Lethal injection is the practice of injecting one or more drugs into a person (typically a barbiturate, paralytic, and potassium chloride) for the express purpose of causing death. The main application for this procedure is capital punishment. The drugs cause the person to become unconscious, stop breathing, and develop a cardiac arrest, in that order. First developed in the United States, the method has become a legal means of execution in China, Thailand, Guatemala, Taiwan, the Maldives, Nigeria, and Vietnam, though Guatemala abolished the death penalty for civilian cases in 2017 and has not conducted an execution since 2000, and the Maldives has never carried out an execution since its independence. Although Taiwan permits lethal injection as an execution method, no executions have been carried out in this manner; the same is true for Nigeria. Lethal injection was also used in the Philippines until the country re-abolished the death penalty in 2006. Although primarily introduced as a more "humane" method of execution, lethal injection has been subject to criticism, being described by some as cruel and unusual.”

   Conceptual and Scientific Defects in the Supreme Court's "Method of Execution" Jurisprudence.

   The Yale journal of biology and medicine (Dow & Newberry)Published Dec 20, 2019Checked Oct 11, 2026

   “The Eighth Amendment to the US Constitution prohibits the infliction of cruel and unusual punishments. However, no method of executing prisoners has ever been deemed by the Supreme Court to constitute Cruel and Unusual Punishment. Constitutional challenges to the dominant mode of executing prisoners today - lethal injection - are hobbled by a lack of clinical data that would reveal the likelihood this method might inflict gratuitous pain. Here, we assess the contemporary Eighth Amendment jurisprudence, including its legal and scientific limitations, and suggest modifications.”

   The lethal injection quandary: how medicine has dismantled the death penalty.

   Fordham law review (Denno)Published Oct 1, 2007Checked Oct 11, 2026

   “Lastly, the Article discusses the legal developments that led up to the current rush of lethal injection lawsuits as well as the strong and rapid reverberations that followed, particularly with respect to medical involvement. This Article concludes with two recommendations. First, much like what occurred in this country when the first state switched to electrocution, there should be a nationwide study of proper lethal injection protocols. An independent commission consisting of a diverse group of qualified individuals, including medical personnel, should conduct a thorough assessment of lethal injection, especially the extent of physician participation. Second, this Article recommends that states take their execution procedures out of hiding. Such visibility would increase public scrutiny, thereby enhancing the likelihood of constitutional executions. By clarifying the standards used for determining what is constitutional in Baze v. Rees, the U.S. Supreme Court can then provide the kind of Eighth Amendment guidance states need to conduct humane lethal injections.”

   When the Islamic State Kills: Ironies of American and ISIS Executions.

   “These research notes explore the idea of comparing executions in the United States (US) to executions undertaken by the Islamic State of Iraq and Syria (ISIS). Is it possible that America's ostensibly rational, formal, and "clinical" death penalty is more painful for its victims than ISIS victims? I investigate this question by considering the suffering caused by the death penalty in the US, making some informed speculations about ISIS executions, discussing execution in two influential Islamic nations, and observing some ironies these topic raise about the rule of law and capital punishment. My goal with these notes is to spur interest in comparative research on state violence and the death penalty.”
