I have bought weed from total strangers in: México, The Bahamas, Jamaica, Costa Rica, Colombia (it is legal there though) , Argentina, Perú, Thailand, Spain, Portugal, Australia, New Zealand, and Canada (as well as my native US where I can now do so legally). I only do it "on the spot," meaning if they don't have it with them I don't go anywhere or wait around or anything. Then I leave immediately and don't return to that general area for a couple of days at least. I have never had a problem.
Yet.
