Up to a third of the population of some of the east European countries are alcoholics.
I'm not saying bans are the solution, but ignoring problems just because you aren't affected isn't a great idea either.
I expect it's worse in Russia, but there's not much in reliable stats.

Alcohol consumption is down significantly there and has been on the decline. They’re not even in the top 15 countries who consume the most:

The important bit seems to be whether something is physiologically capable of getting humans addicted.
Of course banning isn't a credible solution, but recognizing the problem is important by itself too.
