Nah, I don't think so. My dad smoked weed in the 70's, and he is fine to this day, doesn't smoke anymore, bue he quit after 20yrs of smoking it. He's very, very successful aman and very smart...no mental illness of any kind.

Me, on the other hand, I am bi-polar, but I don't believe that is from MJ. My mom has depression, which she got from her mother as well, which I believe MJ is not responsible for my bi-polar, it just runs in the family. I'd take this over heart disease and cancer anyday.
