Just by coincidence, this new study on alcohol consumption popped up
today:

Light to moderate drinking has been associated with beneficial
effects
on health. But a study of 5,766 working Scottish men who were
followed
for 21 years showed no association between coronary artery disease
and
alcohol consumption after adjustment for potentially confounding
factors. There was, however, a strong relation between stroke and
consuming more than 15 drinks a week. Men who consumed more than 35
drinks a week faced twice the risk of death by stroke as did
nondrinkers. The risk of mortality from all causes was higher for
men
consuming more than 22 drinks a week.

mortality from all causes, coronary heart disease, and stroke:
