One drink of alcohol is unlikely to lead you to become unstable. I don't know about the others.
I didn't call for a blanket ban. LSD may have therapeutic uses (other debilitating drugs like paracetamol do), but the self-dosing that people do 'for fun' shouldn't be tolerated.
Sorry, I figured doctor prescriptions were not included. My view is that they should be a controlled substance, the way they are now. You'd have to show amazing cognitive effects for an illness to legalize it for prescription. I don't know the science here though.
By 'absolute ban' I mean they should be controlled, and classified as an illegal drug. This is not something people should self-medicate. Those using without a prescription or worse, distributing, should be jailed.
