Heart disease kills most people. It's probably going to kill most of us, lets be honest. Also he was a boxer which didn't help him, and also he used drugs, but that really has nothing to do with heart disease.
Jesus. After all that, life threw him a curveball. I'm sure even Johnny figured it would eventually be drugs.
Happens a lot. The damage has already been done. Going cold turkey is probably as dangerous as taking it in moderation.
And his drug of choice (cocaine) I'm sure is the main reason he died from it. Seriously, talk to any cardiologist and they'll tell you there is nothing worse for your cardiovascular system than coke.
