Just because something is considered normal, does not make it OK - But it is the same in Denmark and I think it is a big problem. For instance first week in university is 1 week just with drinking and drinking every friday and saturday is normal. But drinking 7-8 times a month makes you an alcoholic in my opinion. ( i know university is +18 and not the 13-14 year old kids).
But it is a culture problem in my opinion.
