Why start to smoke when you know it causes cancer? Smoking is an addiction to people. Tobacco smoke contains nicotine, a drug that is addictive and can make it very hard, but not impossible, to quit. More than 400,000 deaths in the U.S. each year are from smoking-related illnesses. Smoking greatly increases your risk for lung cancer and many other cancers. Cigarette smoke is harmful to both smokers and non-smokers. Around 70 per cent of the tar in cigarettes is deposited in the smoker's lungs. Tar in the lungs will reduce the amount of air the body takes in. Cigarette smoking and second-hand smoke could also cause bone loss, damaged blood vessels, decreased energy, and shortness of breath. Don't start to smoke and if you already did its never to late to quit.
