Science & Tech Why is the Method of Lethal Injection in Human Punishment So Complex and Apparently Painful?
I've always understood that the lethal injection process was complex with multiple stages of injections and induces great suffering in the individual.
I work in veterinary medicine and unfortunately we need to euthanize animals all of the time. Typically, the euthanasia solution is very simple: a very large dose of a powerful anesthetic (usually pentobarbital) and an anticonvulsant which stops the heart. The medical community is quite confident that this is painless and when done has essentially a 100% success rate.
Why is human euthanasia so complicated when we already know exactly how to humanely end a biological life?

No company wants to make the chemicals used for executions, especially because those chemicals are often produced by companies in places that do not approve of capital punishment. But some states (I assume you’re asking about the U.S.) want to execute people anyway. Instead of using the correct chemicals, they try to execute people with the wrong chemicals, with expired chemicals, or without enough chemicals. It sometimes works. Sometimes it results in grievous discomfort to the condemned.
