I have met a lot of people who have experience psychedelics, and I know people who avoid them after a negative experience (much the same way people avoid tequila after one particular night), but I'm yet to meet anybody, or hear of anybody, who has had long term negative effects from psychedelics that requires medication.

I'm sure that maybe they do exist, but it's an exceedingly small percentage of people who try them. People are also allergic to peanuts, yet we don't ban peanuts for the few that will die if they come into contact with them.
