2 Years Ago: Oklahoma Governor Signs Bill Giving State The Option To Use Nitrogen Hypoxia As A Method Of Execution

The above is my version of title from April 17, 2015 by The Guardian.

I missed this story from April 2015.

Oklahoma is the only state with nitrogen hypoxia as a method of execution. They also have the firing squad as another method.

South Carolina considered nirogen hypoxia in 2016 but it never got to the floor for a vote.

I would assume that other states with capital punishment would go to nitrogen hypoxia as an alternative method of execution as the left has lethal injections tied up in court.
