As most of you already know, in many countries, doing drugs are parts of their culture and rituals and is considered healthy even if it's declared illegal by the authorities. e.g. Psilocybin mushrooms have been recently banned in Bali and few other touristic islands in Indonesia.
So it might be a traveler's question to know how and where to buy a so-called-drug safely. As there are a lot of scams and traps running against tourists.
I went through the help and I couldn't find any reasons not to ask such questions on Travel SE. Is "Where and how to safely buy X drug in Y city?" off-topic? And if yes, why?
