US eyes using first-ever death penalty with nitrogen inhalation

Alabama is seeking to become the first state to execute a prisoner by making him breathe pure nitrogen, Report informs referring to ABC News.

The Alabama attorney general’s office on Friday asked the state Supreme Court to set an execution date for death row inmate Kenneth Eugene Smith, 58. The court filing indicated Alabama plans to put him to death by nitrogen hypoxia, an execution method that is authorized in three states but has never been used.

Nitrogen hypoxia is caused by forcing the inmate to breathe only nitrogen, depriving them of oxygen and causing them to die. Nitrogen makes up 78% of the air inhaled by humans and is harmless when inhaled with oxygen. While proponents of the new method have theorized it would be painless, opponents have likened it to human experimentation.

Alabama authorized nitrogen hypoxia in 2018 amid a shortage of drugs used to carry out lethal injections, but the state has not attempted to use it until now to carry out a death sentence. Oklahoma and Mississippi have also authorized nitrogen hypoxia, but have not used it.

The disclosure that Alabama is ready to use nitrogen hypoxia is expected to set off a new round of legal battles over the constitutionality of the method.

Alabama attempted to execute Smith by lethal injection last year, but called off the execution because of problems inserting an IV into his veins. It was the state’s second such instance within two months of being unable to put an inmate to death and its third since 2018. The day after Smith's aborted execution, Gov. Kay Ivey announced a pause on executions to conduct an internal review of lethal injection procedures. The state resumed lethal injections last month.
