No, what most likely happened is that he got addicted to painkillers after his foot surgery.  That led to no longer being given the pills, and with him in Hollywood; there's absolutely people that have something a bit stronger to take care of it.    I figure he was meeting his dealer in a hotel room, rather than the back alley, because he is a well known, fairly well off, minor celeb.  Since he was on at all times of the day, never demonstrated any symptoms of drug use; this was fairly new for him, or he didn't use much (don't know if that's possible with the hard stuff).  This batch had to be really strong or was tainted in some way. That's my take. I do hope that the drug dealer and him were professional, meaning no funny business.  Would be easy to blackmail him, so hope the dope didn't come with a blowjob chaser. TL;DR - I figure death from OD by heroin.   It's a bad thing people are so addicted.  Gee, I wonder who did that.
