I personally know 2 people who suffered from a bad trip. One who thought demons were out for them for about a month and another who just had some wild mood swings for a couple weeks afterwards. Both were temporary but the effects of a bad trip are no joke. There's one other extreme example where someone I'm acquainted with did a lot of psychedelics over the course of a summer who seems permanently changed (although not ill or non-functioning in any way) but there's too much that could've happened outside the drug use that summer that could have affected him for me attribute those changes to drugs (although many other friends did).
