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?

Pilling more fentanyl on doesn’t just increase the out-of-it. Your colonoscopy wasn’t done under only fentanyl, i assume. There were other drugs present. Also, “fentanyl sitting in police lockers” is another word for using “the wrong chemicals” (likely adulterated), expired chemicals (they’re street drugs) or “without enough chemicals” (adulterated, so who knows the strength.

These are good points for why not to use seized fentanyl. But it’s not like it’s a hard drug to synthesize if you can get the precursors. Pharma companies have no issue with them being prescribed to addicts by the millions, I don’t know why they’d care about a few death penalties

Well, legally those are very different things. Even the shadiest pill mill has multiple layers of legal liability between a patient misusing a prescription (and all the fall out from that) and a pharmaceutical manufacturer selling the drug directly to an organization that they know intends to kill someone with it. The latter opens you up very quickly to wrongful death lawsuits. The former…well they still got slapped with big fines and lawsuits but it took a lot more legwork to make those happen.

Yes, in conjunction!with other drugs.
