Since WHO decided to include them in their survey (so at least since 2002) and since they and UEFA came to conclusion that they cannot upkeep 'fair play' with the Middle East nations (which is since 1992 or 1994 as full member).
I'm surprised more countries aren't included since, in many, it is the custom for children to drink wine with meals. I'm particularly surprised that Spain, Portugal and France aren't on the list, as those are countries where I especially observed this custom.
