Addiction is defined as repeated use of a psychoactive substance or substances, to the extent. Nicotine addiction is the fundamental reason that individuals persist in using tobacco products, and this persistent tobacco use contributes to many diseases. Smoking is primarily practiced as a route of administration for nicotine through the lungs; it is a way of getting nicotine into your system rapidly. When a person smokes, it causes a short-term increase in blood pressure, heart rate and the flow of blood from the heart. The smoke includes carbon monoxide, which reduces the amount of oxygen the blood can carry. Carbon monoxide can also damage the inner walls of the arteries, allowing fat to build up. This causes the arteries to narrow and harden and a person may be at risk for a heart attack.
