Cokeheads run in their own circles everywhere. They're around in every country, but you might not be friends with them. Which isn't, frankly, a bad thing. The people that can do that responsibly are the least likely to do it. The people that do it are the worst kind of people to be doing it. I don't begrudge people their little vices or whatever, but people tend to get impaired and do dumb shit -- which is of course not specific to cocaine. Ah, life.
