aight aight, my bad. i cant provide any ground for my claims to stand on (i have no idea where to find the fda paper on it) so for the mean time birdgirl, you win. all i can remember on this subject is i learned this from an educational tv show (i think) called "bullshit!". the hosts are a fat guy in a pony tail and a skinny guy. the tv show is supposed to disprove misinformation and a link to the website to watch it was posted on here a while ago, but i cant remember the name of it nor the poster. maybe someone else remembers..... but, you have won this battle for the mean time birdgirl, you have won.
i will say this tho, maybe its because your lungs were still developing and they were exposed constantly to smoke, just smoke in general.
actually, personally, i would love to watch people suffer in the pulmonary ward and if i ever end up there i will enjoy watching the suffering of them 24/7 while i slowly die, but thats just me.
