Considering exposure to smoke has a cumulative effect, it would be hard to say if there is a "safe" concentration. I don't think smokers realize just how far their smoke travels when dissipated enough to not be a visible cloud. If I'm sitting at a traffic light, and the person in the car in front of me lights up and we both have our windows open, I can smell it pretty strongly even though there's no visible smoke. The same thing with living in apartments. When I lived in apartments and have had neighbors who smoked in apartments adjacent to mine, that smoke odor permeated into my apartment as well; it's actually a big reason why I don't like living in apartments or condos, because having the neighbors' smoke invading my "home" is just plain disgusting to me. Is it just an unpleasant odor at that distance or am I still being exposed to the harmful effects of that second-hand smoke, I really don't know. Someone who has just come inside from smoking a cigarette still has a strong enough odor on their clothing to be irritating, not just unpleasant, but to actually feel like my nasal passages are burning and sometimes to even make me cough...along the lines of when the custodian uses the strong cleaning supplies in the restroom that make my eyes water too, or when someone is practically bathed in perfume (I wish I wasn't exposed to those chemicals either).honestrosewater said:Why can harmful concentrations of second-hand smoke not be avoided? I don't know what concentrations are harmful, but standing outside on my porch, the smoke seems to be diluted (or dilute?) quickly. Is being outside not enough?
I honestly have no idea if that's just an irritating smokey odor at that point or if there is still something harmful to my lungs in whatever is still emanating from the smoker's clothing to cause the odor. I think that would be good to know when determining what is and isn't an acceptable location for smoking or distance to keep from nonsmokers if you're going to light up a cigarette.
What really bothers me is watching people at the hospital coming out the door with their newborn baby, and as they are strapping it into the carseat, they're already lighting up a cigarette.
