Way off. In fact, go pick up the newest issue of SKIING mag, and they have a huge article all about him. He is suffering from seizures, so much so that he went to the Mayo clinic in Minnesota to have it checked out. They got so bad he was waking up with black eyes and bloody lips from seizures. BAM!
He's also one of the biggest stoners that has ever lived. A quote from the mag "Jamie would get himself blackout drunk the night before, wake up in the morning and make himself throwup, and take 3 or 4 bong rips...all before his morning coffee!"
