what you mean, the smoke goes in to the persons lungs, leaves a load of tar on the side and CO in the the persons blood, and then comes out with more tar and CO and nicotine.
Secondhand smoke is not the smoke the smoker exhales, it is the smoke that the smoker never inhales.
if second hand smoke has more nicotine and carcinogens, that would mean it would be cleaning the smokers lungs.
No, because the secondhand smoke never enters the smoker's lungs in the first place.
There was an older gentleman that had a workshop next to my father's (before we moved shop). His pipe tobacco made added a very light tinge of the most delicious smelling tobacco I've ever smelled. On top of that, he was a master at wood turning - so when I went to work with my father as a kid, I'd poke my head in to see what was being made on the wood lathe :)
You know... I've always wondered about that. Because I have heard that "fact" too. I wonder because -- second hand smoke permeates the air surrounding the smoker and, as all humans do, the smoker as well as the second hand "smokee" breathes in this second hand smoke air mixture. So, wouldn't that mean the smoker is getting not only the smoke direct, but also the second hand which therefore means the smoker gets the more of everything (smoke related)?
I don't know - I'm sure there's a few studies testing this topic, that's just my thinking :P
you know...second hand smoke (and i mean the majority of second hand smoke) is actually safer? it's been filtered twice (in most instances) once by the filter on the cigarette and once by the smoker's lungs...the marginal amount of smoke that emanates from the cigarette itself is negligible when you're measuring effects and CO production in the atmosphere...the studies that i've seen (sorry can't produce links) have shown that second hand smoke has somewhere in the range of 10% or LESS carcinogens, CO, Etc... in it than first hand smoke..
Interestingly, the confidence interval had a range containing 1.0 -- meaning that second hand smoke ranges from beneficial to no effect to having an effect. This condition -- it's called statistically insignificant :/ Of course, it's one study -- but not only is it from a very respectable source it's from the authority on health research o.0
Still, I'd prefer not exposing myself - I'm just not going to complain about someone that admits knows it's unhealthy :P
I've included the paper that has since been buried by the WHO.
Here's proof
