I gave up sucking 100% oxygen after a hard night - once I realized the potential for beard-singeing after eating a greasy hamburger.
That, along with the story about oxygen igniting lipstick, is complete rubbish.
At sea level pressure (about 15psi) the partial gas pressure of even a pure (100%) oxygen atmosphere (about 3psi) is 2-3 of orders of magnitude below that required to ignite these substances.
You need an ignition source to make it go off.
