Organic chemistry is the study of compounds containing carbon. It is called “organic” because scientists used to think that these compounds were found only in living things or fossils. However, vast numbers of different carbon-containing compounds can now be produced artificially in laboratories and factories, for use in industry. For example, drugs, plastics, and pesticides are all synthetic organic substances. About 4.5 million of the 5 million compounds known today contain carbon.

The following ailments are prone to occur in cigarette smokers:
1. Cancer of the lung. Heavy cigarette smokers are 30 times as liable to develop cancer of the lung as non-smokers are. There is overwhelming evidence that lung cancer is caused by cigarette smoking.
2. Bronchitis and emphysema. Prolonged cigarette smoking commonly leads to progressive cough and breathlessness, ultimately leading to respiratory incapacity. Gastric and duodenal ulcers take longer to heal in cigarette smokers.
