Actually, a CT scan can differentiate between smoke damage and WG damage in the lungs. Smoking damage appears more as a silt gathered usually at the bottom of the lobes while WG damage is usually in the form of lesions & interstitial 'marks' (I have no idea what doc meant by that!!). I've smoked, albeit sparingly (half pack a day, maybe - a closet smoker, etc.), for 45 years, docs pointed out that my lower right lobe has 12% damage from that time of smoking...hmmm, do the math, there are 5 lobes. Considering the kinds of jobs I've worked, the urban smog, and a few chemicals I've absorbed....not bad at all! LOL! No, please don't lecture on the pitfalls of smoking, I'm CRAZY, not dumb...hehe!
