Anyone who's been in a psychedelic community for long(stoners, deadheads, etc) knows at least a few people who have been temporarily(1 day - 1 year) or permanently fried from having experienced one or many trips. I feel like there is often a backlash against our regressive legal approach which tends to accentuate the positives and diminish the negatives but really we need information. These drugs can permanently change your personality in some ways that will generally not be seen as positive. Yes, they can have many good effects but that comes with a small risk of extreme side effects.
