This video demonstrates the impact that one cigarette has on your lungs.  Look at the color of the cloth used to filter the smoke out of those two holding containers.  That is what ends up in your lungs after one cigarette!

You can try this experiement for yourself - all you need is a cigarette and a handkerchief or tissue.

1.  Take a puff of smoke and hold it in your mouth. Do not inhale it into your lungs. 

2.  Take a white handkerchief and hold it up to your mouth. 

3.  Exhale the smoke through the material of the handkerchief and you will be able to see the tar that is usually deposited in your lungs with every inhalation of cigarette smoke.  Imagine how all that residue adds up over the months and years!
