Via The Wire: ‘Jay Chapman is the creator of the most commonly used lethal injection protocol, which he concocted in the late 1970s. This lethal recipe was adopted by 37 states. Chapman’s protocol called for three drugs: sodium thiopental, a sedative; pancuronium bromide, a paralytic agent; and to stop the heart, potassium chloride. However, in the last few years, manufacturers have pulled away from selling these drugs to states for the purpose of lethal injection. Sodium thiopental, the key sedative in the protocol, has become virtually unavailable. The last manufacturer of sodium thiopental in the United States stopped producing it in 2011. The European Union banned export of it all together, and India has banned its sale. While some states attempted to stockpile the drug before the bans, sodium thiopental has a shelf life of only four years, with expirations fast approaching in 2015.

Suddenly, states were left with prisoners on death row, and no way to kill them. They had to reinvent the lethal injection. On July 23, convicted murdered Joseph Wood was executed by the state of Arizona. His execution took almost two hours, involving fifteen doses of an experimental drug combination. Witnesses watched as he gagged and choked for the majority of the two hours, his opioid receptors filling with hydromorphone and midazolam.

An …official told the judge working to find an acceptable lethal injection protocol that “You’re not entitled to a pain-free execution.” This mentality is a point of contention on both sides of the execution battle. While some believe a painful execution qualifies as cruel and unusual punishment, others believe that with murderers who are guilty of terrible crimes against humanity, the end is more important than the means.’
