this is so crazy... ive got a nutz-o story about my friend that i think had this now that i am reading up on it. He started smokin weed like 3 years prior to this event and then one day it just hit him. Like he was trippin hard core.. he was over at a friends house getting high, and just as he was going home, his friends mom showed him to the door and he asked her " Can you see that?," "theyre everywhere" and his friends mom asked "who?" you know like what the hell is this kid talkin about. his illusions and state of being totally went out of wack, telling nurses in the hospital he had a knife, and all this crazy shit.. he was then sent to a bigger hosipital in a bigger city for tests and shit, and when he came back he was the same old dude.. But when he tripped like that its like he was a totally different person.. now a year later hes still hittin the doobs and hes fine...ive read somewhere smoking weed causes schizophrenia in some people.. so i dunno just thought id share on the topic Peace!
