While the article said he used steroids, it also said he was a cocaine user. Steroids aren't without risks and side effects (an opinion from one who has used them), but I'll go with the coke use on this one. And who knows, with all his physical problems, he may have been a heavy Vioxx user too (an anti-inflammatory...I just switched off of mine), which has just been pulled for raising heart attack risk.
I guarantee you there are lawyers looking at his Vioxx use. Who you gonna sue if your client dies from too much blow?
