The Man
Franks and beans!
no offense personally, but that's really kind of a dumb question. he was a heroin addict. that shit takes control of you and won't let go. he made the same mistake many have made before him and either got some bad stuff or shot up a little too much and he couldn't handle it. it's obvious that he was already weak before he died. in an interview not long before his death he was talking about losing teeth and shitting his pants because of loss of bowel control from his addiction. it was obviuos near the end that his trip was almost over.
