It’s not in the UK at any rate, the average varies between 12 and 17 units of alcohol per week depending on age with most of that falling on Fridays and Saturdays. 2 cans of beer per day works out at 28 units, so is certainly substantially more than average. I would guess there is a bubble affect though, most of my friends drink only on special occasions line parties, and regular drinking at home would be perceived as alcoholic behaviour by most of them.
