This is a straw man argument, having a permanent mental change after having a "bad trip" on psychedelics is not analogous to drinking a beer or too much whisky and doing something dumb(or worse). There is not evidence that a person consumes one drink and goes into psychosis or has permanent mental changes like with psychedelics. I am not against having psychedelics for certain situations(under controlled situations) but you are playing with fire and your mind and sanity are the tinder and are rolling the dice so to speak.

Citation required. I have yet to see a single reputable paper or study that describes a 'permanent mental change' for the worse, like psychosis, after a single encounter with psychedelics.

What are the negative permanent effects of a "bad trip"?

[drak0n1c]

Perhaps not a single bad trip, but a couple years of bad drug habits can lead to permanent brain damage among those who aren't careful and knowledgeable about what they ingest and the dosage. It is a factor in the homelessness crisis.

Right, opoids and meth and etc can cause permanent brain damage over time. But psychedelics...?
