I genuinely can't be convinced there are people alive today that the risk of one scented candle in the home and/or plug in air fresheners are higher than the background danger of auto, industry, and just general pollution. This seems like an anxiety in search of a problem, or am I very underestimating it?
It just seems like the road in front of my house is probably more of a problem than my vanilla candle.
I once forgot to extinguish a candle before going to bed, it burned down, and produced a massive amount of soot. Their was a stripe of black suit on the wall where the candle was standing, a black spot on the ceiling, and my upper lip and nostrils were black from soot.
I'm not sure what effect on my health a one time event like this has, but if I can avoid it I will.
