Cigarette smoke contains particles and these collect in the epithelial cells covering the surface of the airways. The cilia of the epithelial cells of the airways may be paralyzed by chemicals/toxins in the cigarette smoke and then they cannot move trapped particles up towards the throat. Smokers find it hard to give up the habit because of nicotine in the smoke which is an addictive drug. The tar in cigarette smoke is thought to cause damage to cell ciliated epithelial cells and this may lead to lung cancer. Among the many poisonous chemicals in cigarette smoke is carbon monoxide and this joins with hemoglobin in Red Blood Cells (RBC) cells and stops them carrying oxygen gas.
