True, however what the studies DO show at the very least is that, given a predisposition to this type of illness, there is evidence to suggest that drug use creates episodes that may not have occurred otherwise. Can you say that a heroin-addicted individual currently being treated for schizophrenia would have shown symptoms at all if they had never taken drugs? How many people are walking around now with a genetic disorder who will never know they have it because it is never triggered? I just think there is too much that is not well enough understood to be able to make definitive statements about it one way or the other.Quote:
