How long does it take to pass out breathing pure nitrous oxide?
Q: I've heard that a nitrous user can blackout after just 2 minutes of breathing the pure stuff. Somebody else told me it takes 10 minutes and I don't plan on seeing for myself. So can you please tell me who's right?

A: The body needs oxygen, and without it, will pass out. Breathing pure nitrous oxide, it would take just about exactly as long to pass out as it would if you weren't breathing at all. 2 minutes is about right.

That's why dentists mix nitrous oxide with oxygen, and why recreational users should always take breaths of air between hits of nitrous.
