Hm, I found this:
tobacco smoke contains many harmful substances (benzpyrene, nitrosamines, carbon monoxide, soot, etc.)
let's see:
soot, carbon monoxide - diesel trucks and cars on the street produces much
more than cigarettes
carbon monoxide - a) used for processing meat and fish, give them a bright red color and appearance of freshness, without changing the taste, b) is a major atmospheric pollutant in some
urban areas, chiefly from the exhaust of internal combustion engines (including vehicles, portable and back-up generators, lawn mowers, power washers, etc.) -
much more than cigarettes
nitrosamines - cured meat, etc (food)
benzpyrene - in automobile exhaust fumes, tonns in charbroiled food (do you love Grilling?..) and in burnt toast (have you toaster?)..
So, it's not about to stop smoking but stop eating cured meat, fried food, grilled food, wok, stop to use your cars,
throw your toaster - all of this is 90 % of cancer (and only 10 % is cigarettes)
Otherwise, it's little silly to exchange 10 % of benzpyrene (cigarettes) in daily ration to 110 % extra аcetone, formaldehyde, acetaldehyde, etc...
