Someone offered me some marijuana the other day. I said no thank you because I have heard that people with schizophrenia shouldn't smoke marijuana. I have been offered marijuana several times in my life and have always said no, even before being diagnosed with schizophrenia. My question is why is it such a bad thing for people with schizophrenia to smoke marijuana as opposed to those without schizophrenia. My brother has bipolar disorder and I am pretty sure it is not a coincidece that he had an episode of hypomania after smoking pot. I have heard marijuana and people with bipolar disorder don't mix either. I must admit I am curious to try it but don't think it's a good idea.
