I was just wondering where that figure came from and if it was accurate. I generally try to hold in all of my inhales till it's all absorbed, but if you're only gaining 15% at the most more smoke, then maybe it would be more beneficial to take more drags w/ normal hold times, as it would seem that the thru the duration of a cig that more drags w/ normal hold times would end up being more than fewer drags w/ long hold times. Any thoughts on this? V notes: Just added the image link. The figure was widely reported in anti-smoking public health literature several years ago. I'm not at all sure about the accuracy of this estimate, but when you stop and think about what the lungs are designed to do, the vast surface area of the airways and alveoli, as well as how relatively dense and sticky cigarette smoke is compared to air, the absorption percentage estimate doesn't seem at all far fetched, at least to me. As for your question – I have no idea, but it would seem reasonable to assume that the longer you hold any drag of cigarette smoke, no matter how often you take drags, the more material your lungs would absorb...
