The nicotine in each cigarette causes the body to change. It causes the heart to beat faster the blood vessels to narrow the flow of blood to slow down the blood pressure to increase and the body temperature to drop a little, especially in the fingers and toes. Cigarette smoke contains almost 4,000 chemicals. Among them are small amounts of DDT, arsenic and formaldehyde. Almost 90 percent of these poisons stay in your lungs after smoking a cigarette.
Smokers have twice the death rate as nonsmoker.
They die of lung cancer and heart attacks. Many older people began smoking cigarettes before the dangers were well known. Cigarette ads once ran on TV and radio. TV and the movies made smoking look glamorous. No one talked about the dangers.
