You have any schizophrenia in the near-family? I know it's genetic. Doesn't mean that someone still can't develop it if no one in their family has it. I got an aunt who's schizophrenic - it doesn't look fun....

headshake was right that hallucinogens are a symptom of schizophrenia...and as far as worrying about having a mental problem someday, don't worry about it so much - or you might!

ps...see a doc
