Methods of Execution

Lethal Injection

Though lethal injection has been used for a majority of the executions carried out in the modern era, it is plagued by problematic executions and controversy.

Overview 
 

All states and the fed­er­al gov­ern­ment use lethal injec­tion as their pri­ma­ry method of exe­cu­tion. Jurisdictions use a vari­ety of pro­to­cols typ­i­cal­ly employ­ing one, two, or three drugs. Most three-drug pro­to­cols use an anes­thet­ic or seda­tive, fol­lowed by a drug to par­a­lyze the inmate, and final­ly a drug to stop the heart. The one and two-drug pro­to­cols typ­i­cal­ly use an over­dose of an anes­thet­ic or seda­tive to cause death.

Although the con­sti­tu­tion­al­i­ty of lethal injec­tion has been upheld by the Supreme Court, the spe­cif­ic appli­ca­tions used in states con­tin­ues to be wide­ly chal­lenged pri­or to each exe­cu­tion. Because it is increas­ing­ly dif­fi­cult to obtain the drugs used in ear­li­er exe­cu­tions, states have resort­ed to exper­i­ment­ing with new drugs and drug com­bi­na­tions to car­ry out exe­cu­tions, result­ing in numer­ous pro­longed and painful exe­cu­tions. States are also turn­ing to pre­vi­ous­ly dis­card­ed forms of exe­cu­tion, such as the elec­tric chair and gas cham­ber, in the event that lethal drugs can­not be obtained.

At Issue 
 

Even though the issues sur­round­ing lethal injec­tion are far from set­tled, states are attempt­ing to cut off debate by con­ceal­ing their exe­cu­tion prac­tices under a veil of secre­cy. Recently passed laws bar the pub­lic from learn­ing the sources of lethal drugs being used, mak­ing it impos­si­ble to judge the reli­a­bil­i­ty of the man­u­fac­tur­er or the pos­si­ble expi­ra­tion of these drugs.

What DPI Offers 
 

DPI has state-by-state sum­maries of the meth­ods of exe­cu­tion cur­rent­ly in place and the types of drugs used in each exe­cu­tion in the past ten years. A DPI report cov­ers the exe­cu­tion secre­cy laws that have been imposed in many states. Statements from var­i­ous phar­ma­ceu­ti­cal com­pa­nies bar­ring the use of their drugs in exe­cu­tions are also provided.

Department of Justice Withdraws Federal Execution Protocol and Keeps Moratorium on Executions in Place

Three and a half years after announc­ing its inves­ti­ga­tion into the fed­er­al death penal­ty pro­to­col, Attorney General Merrick Garland announced on January 15, 2025 that the Department of Justice (DOJ) is rescind­ing the fed­er­al government’s sin­­gle-drug pen­to­bar­bi­tal lethal injec­tion pro­to­col. The DOJ’s deci­sion was based on what AG Garland called​“sig­nif­i­cant uncer­tain­ty” about whether exe­cu­tions by pen­to­bar­bi­tal caused unnec­es­sary pain and suf­fer­ing. The…

Connecticut Lawmakers Introduce Bill to Prohibit the Production and Manufacturing of Lethal Injection Drugs and Other Materials for Executions

On January 10, 2025, three Connecticut law­mak­ers intro­duced a bill that would make it ille­gal to man­u­fac­ture and sell any drugs or med­ical devices in the state meant to car­ry out the death penal­ty. In 2024, Connecticut-based com­pa­ny Absolute Standards was iden­ti­fied as the source of lethal injec­tion drugs used in 13 fed­er­al exe­cu­tions in 2020 and 2021. In a let­ter to the bill’s spon­sors, John Criscio, President of Absolute Standards, said the com­pa­ny ceased production…

Aaron Gunches Asks for February Execution Date, Raising New Concerns About Arizona’s Lethal Injection Protocol and the Execution of Volunteers”

No jury has ever learned about Aaron Gunches’ life his­to­ry and expe­ri­ences, noth­ing about his child­hood, men­tal and phys­i­cal health, or trau­ma — the mit­i­ga­tion evi­dence that the Supreme Court has said is essen­tial to a con­sti­tu­tion­al death sen­tence. Arizona courts judged Mr. Gunches com­pe­tent to rep­re­sent him­self in two sep­a­rate tri­als for the mur­der of his ex-girlfriend’s hus­band, and he pre­sent­ed no defense in either pro­ceed­ing. Jurors twice sentenced him…

Tennessee to Resume Executions with Single-Drug Lethal Injection Protocol

On December 27, 2024, the Tennessee Department of Correction (TDOC) com­plet­ed a mul­ti-year lethal injec­tion pro­to­col review and announced that instead of the pre­vi­ous three-drug cock­tail, lethal injec­tion exe­cu­tions will use a sin­­gle-drug bar­bi­t­u­ate, pen­to­bar­bi­tal. Ohio was the first state to use pen­to­bar­bi­tal, in the March 2011 exe­cu­tion of Johnnie Roy Baston. State offi­cials now use sin­gle drug pro­to­cols in 14 states, includ­ing Tennessee, as well as in…
