I was probably rambling a bit too much there without making my point clear. What I meant to convey was that I don't believe there is a credible risk of many 10 year olds abusing drugs. And if any of them do it, I think the main problem in their life is not the availability of the drugs. As for drinking in bars, when I say "too drunk" I mean dangerously drunk, not just making a fool of yourself and being rude to the staff. The point is that most bars won't let you die on their premises, or even come close to it. In most cultures, recreational alcohol consumption has a social aspect and this is desirable. Drinking in a field in secret in the dark means that if somebody does get into trouble, it's less likely to be noticed before it's too late. As for people being kicked out of a bar for being too drunk, I think most people would just go home and sleep it off. The sort of person who will go to the effort of acquiring more alcohol and heading off alone to drink in secret probably has other problems. Again, I'm struggling to say this concisely, so I think the important point is that limiting access to alcohol/other drugs merely attempts to relieve one of the symptoms of a larger problem. It's like trying to cure lung cancer with cough medicine.
