C'mon bro, first you were worried house would burn down, then that the flame would burn all the oxygen, now you're worried about carbon monoxide? Which is it?
Other people are worried about benzene and toluene, "clogging and slowing stomata with smoke"... Well, then, if it's carbon monoxide that you're now worried about, you don't need to worry at all!!!
It's a candle, bro. candles produce spurts, just tiny spurts, of carbon monoxide in the smoke when you blow them out. You can find an article talking about the "sulfur poisoning" when you light the match that lights the candle, but let's be real. When there is a flame, the carbon monoxide is so, so infinitesimally small, that.... they're able to make a cheap as hell product known as a "candle", lab tested, grandmother approved, enjoyed the world over, every day in a variety of applications
Even the people who ARE afraid of candles aren't afraid of carbon monoxide! They are afraid of other things they shouldn't be afraid of, like "
benzene and
toluene" oooh... (Here's a study showing no benzene)
If you want visual aid, here. This is a guy who IS afraid of carbon monoxide in candles!!! And, he feels he has proof, and made a video to warn people.. I don't know the man, but I will go ahead and classify him as a bummbling idiot of the highest regard, and his own video proves it a half dozen ways.. Can you find them? It's like Where's Waldo
... Don't be like this dude... as an aid, here is a list of various agency standards for carbon monoxide:

And... a reminder what we're talking about:
I mean, I don't know what to say. I don't know how much documentation is needed here. I never guessed so many people were afraid of candles.
