My diagnosis changes a lot. I am currently diagnosed as bi-polar but at one point I was diagnosed with schizophrenia. So I guess it's possible I have it. But I think it should be fine to smoke. I think they diagnosed me as either a paranoid schizoid or with disorganized thoughts. Something like that. Anyways I don't think anything bad about it, but the people that have it should probally take the anti-psych meds, but they really make you dull and boring.
