I hope you are joking.
New Zealand, Australia, Thailand, Cambodia, Laos, America, France, Turkey, Greece, Crete, Cyprus, Holland, Czech Republic, Canada, Spain, Mexico, Cuba, Fiji...
All these places being drunk is socially acceptable (or at least I have been with people and locals). The only place where people looked like it was frowned upon is Singapore
Holland, Spain, France, Israil, Turkey, Laos, Spain - These places it seems more socially acceptable than others. Parts of Laos sell opium, mushrooms etc in the bars, so seems pretty normal. Amsterdam sells cannabis and used to sell mushrooms, some of the clubs have a policy of 1 ecstasy pill allowed but any more will be confiscated. Ibiza you have people walking around like zombies at 10am from nights before and people drinking constantly. When I went to France when I was 10 there were locals at a bar we went in who got hammered with my dad and uncle then biked home...
