I don’t know that much about Kiss, but I know that Gene Simmons and Paul Stanley didn’t use drugs but Ace Frehley and Peter Criss did. So statistically we’re only talking about two people who lived unhealthy lifestyles.

All five members of Aerosmith went through around a decade of serious drug addiction from the mid-70s (and they already did drugs before that) to the mid-80s and they’re all still alive.
