I have no data to back this up, but I seem to find that regions at Northern latitudes tend to have higher rates of alcoholism. I think it has something to do with long winter nights and people being able to find a sense of community in a pub/bar/Ratskeller after the sun goes down at 16:00 for half the year.
The US is much further south than most of Europe AND there are large regions that are very anti-alcohol due to religious reasons.
Any recommendations on cups? My cups just crapped out
