When you breathe in the cigarette smoke you also breathe in the tar thanks in the smoke. Gradually it will build up on your windpipe – yuck!! That’s why passive smoking is also bad- you don’t need to be the one actually smoking the cigarette to inhale some of the smoke. Scary stuff!
I guess the only thing that I can add is that when you burn a cigarette the tar is heated up so much that it can be taken up in the smoke that you breathe in, but then it coats your windpipe and lungs and sticks there!
