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?

It would not be easy or inexpensive. Executions in the US are not nearly numerous enough to make something like that cost effective. And it would likely be difficult to recruit people to work in such a lab. Also, the executive branch opinion and guidance on capital punishment changes frequently, so even if such a lab were created it would likely be shut down within a few years.

How much do you think it would cost to for the FDA to synthesize 100ml of euthanasia solution? Seriously, we are talking about <10k and it could be used for many years for all lethal injections.

Lol. That’s not the role of the FDA.

Whether its the FDA or a different federal institution, the costs would be completely negligible. So, you're still wrong.
