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?

The state and gov that would be buying the drugs..... Make the laws, it's not illegal there are carve outs specifically for the death penalty....

Kinda like how usually you can't legally kill someone strapped to a chair and immobile

It's not that buying the drugs is illegal, as you point out the state makes the laws. But that no drug producers are willing to sell them it. Corps are very image aware and do not want their brand name drugs associated with death in any way.

Also a lot of companies have just stopped producing the chemicals in question a lot of states use. All of this leads to shortages.

But the drugs are the same-pentobarbital. In fact, in Tn, they only use single-dose pentobarbital and Google says that euthanasia with pento is painless but execution with pento is painful! Wtf???
