Painkillers are temporary. The drugs we are talking about are meant to effect a permanent change on the user.
And pain killers, at least OTC ones, don't alter someone's psyche. We can, more or less, rely on their judgment that painkillers are helpful. You can't necessarily say the same for mind altering drugs.

You'd only say someones judgement about themselves is unreliable if they will contradict themselves later. But if it is a permanent change, then you are talking to the "new" person who is capable of judging this as well as anyone.
The problem is we are talking about something that is orthogonal to the effect. An example is more like getting prescribed anti-depressants for back pain. I hear it helps with the pain, but you are getting personality alteration as a side effect with it.
Like if im suffering pain, I don't want to get drug-induced quasi religious epiphanies from psychedelics. I Just want the pain managed. And what's really annoying about LSD is how it keeps getting promoted as a wonder drug here.
What happens when docs start prescribing it for back pain too?
It's not just about pain management - it's about accepting and making peace with dying. If there's a possibility that a drug can make this process easier for terminally ill patients, why would you object to its use by people who choose it?
