One of the ingredients in tobacco smoke is nicotine, states Healthline. It is a mood-altering substance that stimulates the central nervous system, making a person feel more energized. However, that feeling soon subsides and the body craves more, forming an addiction. Additionally, smoke destroys the air sacs in a person's lungs, causing emphysema. Over time, the lungs lose the ability to filter out the toxins found in cigarette smoke, leading to COPD and cancer.

Smoking also lowers good cholesterol levels and raises blood pressure, states Healthline. This can stretch the blood vessels, allowing a build-up of bad cholesterol, which may eventually lead to atherosclerosis and the formation of blood clots. Smoking can also cause inflammation or infection of the gums as well as increasing the chance of developing mouth, kidney and pancreatic cancer.
