I have a friend whom I used to be very close with but as we all went off to college he stayed at home and fell into a new crowd. He was always a little goofy said weird things made weird jokes thought werid stuff was funny, latly hes moved down to college with all of us and is just working. Hes been acting extremely different talking of crazy tihngs and having crazy ideas and thoughts of paranoia. Hes also become a heavy marijuana user, Im wondering is smoking weed has merley brought about his hidden schizophrenia disorder or if hes just an odd person, my friends and I have gone into much greater detail on the matter with a physcology professor here at school andhe strongly suggest it is the disorder blooming at his peak late teens. ??????
