Have any colleges or high schools been able to moderate dangerous levels of alcohol/drug use?

My daughter, whom I mentioned in an earlier post, spent the summer in England and is now studying in France. While rampant youth drunkenness isn’t as severe as it is in England and the US, they’re not immune to it. One of the kids in her host family (a 17 year old boy) is on a tight leash after his parents had to pick him up from a hospital after he was treated for alcohol poisoning. If he has a hangover after partying with his friends, the other kids in the family are encouraged to be loud outside his bedroom door. Gotta love French parents.
