If this had come up D.A.R.E. classes when we were kids, drugs would no longer even exist.
Having a tripmaster around -- more specifically, someone whose job it is to keep you from jumping out of windows when you do hallucinogens -- has sort of gone out of fashion since the heyday of '70s drug culture. If you ever decide to take mushrooms in the near future, though, you should probably have a friend there to keep an eye on you. Otherwise, you might end up like this guy in Columbus, Ohio who was found naked in a local Middle school after having ripped off part of his penis. Is it possible to feel empathetic phantom dick pains without ever having had one? I might be having those right now.
