For those of you not familiar with it - there is a thing called an oxygen concentrator. You plug it in and it delivers almost 100% oxygen by filtering out the 80% of non oxygen gases in the ambient air. Most forced to use it fucked their lungs up from smoking. And you will find many continuing to smoke butts while they have a cannula in their nose delivering oxygen.
