Temporary insanity is viewed as dangerous. LSD is a particularly harsh substance, so on the scale of psychedelics... I would legalize it right before PCP.
I could classify many a drunk person as exhibiting temporary insanity, and clearly drunk people are dangerous. Should I assume you support prohibition of alcohol as well?
Evidence based dear sir... evidence based. We don't really want to start legalizing drugs based on subjective perception, we want to start having studies and publishing numbers, and make decisions based on them.
