yeah. i replied to you in the other thread about coke and k. i took lsd analogues frequently for a couple years and now it's not really going away.. weed makes it crazy. i didn't really get it for years using shrooms before the lsd analogue use, but shrooms can still cause HPPD for some people..
how old are you and what drugs gave you HPPD? i have schizophrenia too, which is auditory hallucinations. i never had any visual hallucinations with out drugs. i don't really get much HPPD when not smoking pot either.
