Alcohol is pretty terrible for your body and is carcinogenic. Then again, so is sunlight, or, as the parent pointed out, sugar, sat-fats, etc. The difference is I need some amount of sunlight and saturated fat to live.

Alcohol also heavily correlates with assaults, rapes, domestic violence, and murder. Something crazy high like 60% or more of assaults. Ditto for things like car accidents after 9pm -- overwhelmingly alcohol related. DUIs kill a non-trivial amount of people.
