I hate to rain on your parade but I am well aware that O2 doesn't burn. I too took Chemistry 101. My point was that some geezer on oxygen will set the place on fire because the o2 will act to enflame his smoldering cigarette.

I work in an insurance company and the collection of claim photos where just such a scenario has played out too many times to count depicts some of the worst ways to die one can imagine.

I am with you on one point. I was a Firefighter for a very
long time and cannot imagine a more terrible way to die
than from burning. Even the most minor burn hurts like
hell. But that does not change the fact that it would take
a concentration of oxygen far beyond what would be possible
in a patients room to cause a lit cigarette to burst into
flame. In fact, you can direct the oxygen stream directly
onto the lit cigarette and all that happens is the the coal
on the end glows a little brighter. No flame. Although I
never tried putting a lit cigarette in to a filled waste
paper basket and then filling it with oxygen.
