There are certainly deaths/years of life lost caused by excessive drinking.
But on the other hand, there are health benefits of moderate drinking.
There's some presentation of health benefits/problems on the Mayo Clinic web site:
So, one question would be: how may years of life for the entire population are lost from excessive drinking, how many years
of life for the entire population are gained from moderate drinking? And how can moderate drinking be encouraged while
decreasing excessive drinking?
In general terms it appears that Russian men are very adversely affected by drinking (life expectancy ~64), and French women's long
life expectancies (~85) are helped by their moderate drinking.
But culture in general can be very hard to change!
