My family background is Italian. I have relatives there. I have visited there several times. There is no real drinking age there. When I went there as a teenager, I was often sent to the store by a relative to buy wine. No problem getting it. Do you know what the young peole there prefer to drink? A famous American beverage, Pepsi.
In other words, the appeal, and mystery of drinking does not exist there. Teenage drinking binge parties do not either. With young people, the more you try to regulate their behavior, the more appealing you make it.
I've spent three (3) months in Turkey. This was in one-month segments starting in 1979 and ending in 1985. At the time, you could walk in to any pharmacy and pick up, off the shelf, Bayer aspirin with codeine. They also sold a product containing ethylmorphine, which is about the same as codeine.
I talked to a LOT of people when I was there. Very few even were aware this stuff was available. As an American, I certainly was. I knew nobody who had any at home or said they had ever used it. They also sold the equivalent of Darvocet (I think they call it Darval) OTC. Nobody I talked to had that, either.
I had a major sunburn from being out on a boat in the Agean. I was toast and could barely wear clothes. So I went to the pharmacy and asked them what I should do. That's when I was pointed to the shelf with Bayer/codeine. I got two boxes of 24 each. Sunburn pain gone.
So, it seems there is a parallel between the drug situation (at that time, at least) in Turkey and the alcohol situation in Italy. Banning a thing makes it tasty.
Widespread mystery and appeal of drugs doesn't seem to exist there. Certainly there is some abuse. In the bus stations, it is not uncommon to find somebody sitting in a corner smoking opium and begging for change.
Before the Harrison Act (somehow 1934 rings a bell), and even after, you could go into a pharmacy here and get paregoric (opium tincture) and buy Cocaine-Cola. People bought it when they had symptoms they thought it would cure, not to get high, by and large.
The banning of these substances pointed out that there must be something fun about them or they wouldn't need banning, and the drug black market was born.
My guess is that history has treated alcohol similarly. Wine for dinner and a little brandy for most people. Then along came prohibition and alcohol became more closely associated with crime. Prohibition I is gone, but some of that association remains.
I have no problem with police going into bars and talking to or arresting someone who's drunk and belligerent. But to go in and arrest them just because they're drunk if they're contributing to the "happy" atmosphere is wrong. To arrest the same person, or call him a cab, if he appears ready to get into a car and drive it is fine.
