ELI5:Why is it safe to inhale noble gases

I was watching hamilton's pharmacopeia and he was inhaling xenon and seemed to think it was pretty safe. As a layman, my intuition tells me inhaling anything besides oxygen is not safe. Why can you breath pure gases other than oxygen and be fine?

Noble gases don't react. The only real issue is that it takes up lung space where there could be oxygen.

You can breathe in helium to do a funny voice, but make sure your next couple breaths are normal air.
