Chemicals in cigarette smoke affect the entire body.
This is why smoking causes so many diseases,
including a dozen types of cancer, heart disease and various
lung diseases.
Hydrogen cyanide, carbon monoxide and ammonia weaken
the natural cleaning mechanisms that clear your lungs and
airways of toxins. This means that other dangerous chemicals,
bacteria and viruses that you inhale stay inside your lungs.
