A part of smoke that clogs up your lungs?

Answer 1

If you smoke, tar will build up in your lungs. Also nicotine and many other carcogenic chemicals build up in and on the walls of your lungs. Eventually your lungs will loss they elasticy - think of it as blowing up a ballon - u breathe air into it and it expands{much like inhaling| then you let the air out of it {much like exhaling} and the ballon deflated. now think of blowing up a brown paper lunch sack - u blow air into much like inhaling and it expands BUT when let the air out much like exhaling it still pretty much retains the same shape it had when you inhaled. in other words it did not collapse. when this happens you can't express all of the air of your lungs and that is not good. This is when you get short of breath, have trouble walking long distances, sometimes you will get headaches, occassionally bad migraine headaches, a whole laundry list of symptoms all because you wanted to smoke that cigarette. right about now when you ask people if smoke was worth it, worth what its costing them now 99% say no they wished they had never smoked...oops, too late now

Answer 2

Tar is actually the real bad guy in cigarette smoke. However, it does not 'clog' your lungs in the sense of something clogging a sink or toilet. Rather, cigarette tar simply damages the lungs. It does this in the short term by coating the lung tissue and impeding oxygen/CO2 transfer (which COULD be looked at as clogging in a sense). And, in the long term, it causes emphysema and lung cancer.
