Serious consequence: Smoking causes more than four in five cases of lung cancer. Lung cancer has one of the lowest survival rates of all cancers. Tobacco smoke contains more than 70 different cancer-causing substances. When you inhale smoke, these chemicals enter your lungs and spread around the rest of your body. Scientists have shown that these chemicals can damage dna and change important genes.

Nobody truly knows: but the chronic irritation of certain aromatic hydrocarbons in the smoke ("tars") progressively irritates cells, increases the number that die, with new ones taking their place that over many years become more and more abnormal (metaplasia), finally becoming very abnormal (dysplasia) and ultimately becoming cancer (neoplasia). I do not know the exact cellular mechanisms, but some scientists do.
