Pure oxygen is very harmful to humans at pressures higher than ground level, with the effects becoming worse the higher the pressure - ie. when Scuba diving.
At lower pressures, such as the cockpit of a plane at altitude, pure oxygen becomes much safer to breathe, to the point some astronauts have breathed it for around 2 weeks (at low pressure) with no detrimental effects.

It depends on what you mean. We can breathe helium without any ill effects as long as we get enough oxygen.
