OXYGEN CIGARETTES

OK guys, so I'm doing some work on a movie and please bare in mind it's fictional (hey,it's the movies!). But I need a character to smoke an oxygen cigarette(please don't ask why). Now, I'm talking about one of those metallic contraptions, I'm talking about something that actually looks like a real cigarette and unless you pulled it apart and examined it's "anatomy" you wouldn't know the difference. So I've come up with this idea that the cigarette is comprised of briquetted sodium chlorate and the cigarette paper is lined with thermal insulation. Would this theoretically work? If not, why? And do you have any suggestions on how to devise an oxygen cigarette that might not necessarily be realistic but, at the very least, scientifically sound?

Thanks guys. I really appreciate any help you can offer.
