Psychedelics can cause HPPD (temporary) and Visual Snow Syndrome (permanent) in people, where they hallucinate while completely sober, sometimes indefinitely for the rest of their lives.
As someone with Visual Snow Syndrome (not contracted from drugs) it is a private living hell that risking it is not worth whatever trade off you get from discovering yourself. This is going to rub some people the wrong way on HN, but until we know more about these neurological conditions, I wouldn't recommend doing these drugs outside of a clinical setting where there are very clear benefits.
