I think the middle ground is, "medically supervised with informed consent" like we do with every other prescription medication. You wanna drop acid, take molly, pop an addy, or k-hole yourself, have a blast. Get a doctor to sign off that you know how it works, how to take it safely, what to do in an emergency or overdose situation, and that you don't have any complications with your health or other prescriptions.

It would at least be a safer and more honest policy about what the current state of recreational drug use is like in the US.
