i dont think alcohol is considered a drug, anyway,porto, i love red wine, especially portuguese wine(there is no drink like a 10 year old porto), french wine isnt to bad either, well, brasillian cachaça and mexican tequilla are very tasty also but they scratch a little.
if you want to get drunk i advise you to try "receita" dont know its english name, its made of white wine, beer, and suga,
