Quit Smoking
Nicotine is the addictive drug in tobacco smoke that causes smokers to continue to smoke. Addicted smokers need enough nicotine over a day to “feel normal” – to satisfy cravings or control their mood. How much nicotine a smoker needs determines how much smoke they are likely to inhale, no matter what type of cigarette they smoke.
Along with nicotine, smokers also inhale about 4,000 other chemicals in cigarette smoke. Many of these compounds are chemically active and trigger profound and damaging changes in the body. There are over 60 known cancer-causing chemicals in tobacco smoke. Smoking harms nearly every organ in the body, causing many diseases and reducing health in general.
Tobacco smoke contains dangerous chemicals. The most damaging compounds in tobacco smoke include:
- Tar. This is the collective term for all the various particles suspended in tobacco smoke. The particles contain chemicals including several cancer-causing substances. Tar is sticky and brown and stains teeth, fingernails and lung tissue. Tar contains the carcinogen benzopyrene that is known to trigger tumor development (cancer).
- Carbon monoxide. This odorless gas is fatal in large doses because it takes the place of oxygen in the blood. Each red blood cell contains a protein called hemoglobin; oxygen molecules are transported around the body by binding to, or hanging onto, this protein. However, carbon monoxide binds to hemoglobin better than oxygen. This means that less oxygen reaches the brain, heart, muscles and other organs.
- Hydrogen cyanide. The lungs contain tiny hairs (cilia) that help to clean the lungs by moving foreign substances out. Hydrogen cyanide stops this lung clearance system from working properly, which means the poisonous chemicals in tobacco smoke can build up inside the lungs. Other chemicals in smoke that damage the lungs include hydrocarbons, nitrous oxides, organic acids, phenols and oxidising agents.
- Free radicals. These highly reactive chemicals can damage the heart muscles and blood vessels. They react with cholesterol, leading to the build-up of fatty material on artery walls. Their actions lead to heart disease, stroke and blood vessel disease.
- Metals. Tobacco smoke contains dangerous metals including arsenic, cadmium and lead. Several of these metals are carcinogenic.
- Radioactive compounds. Tobacco smoke contains radioactive compounds, which are known to be carcinogenic or cancerous.

Health Tips
Excercise. More than 50% of American men and women do not get enough physical activity to provide health benefits. For adults, thirty minutes of moderate physical activity on most, preferably all, days of the week is recommended. It doesn't take a lot of time or money, but it does take commitment. Start slowly, work up to a satisfactory level, and don't overdo it. You can develop one routine, or you can do something different every day. Find fun ways to stay in shape and feel good, such as dancing, gardening, cutting the grass, swimming, walking, or jogging. Read more Health Tips »
