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’, 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. Tobacco smoke contains over 69 known cancer-causing chemicals, which can harm nearly every organ in the body, causing many diseases and reducing health in general.

The most damaging components of tobacco smoke:
Tar – this is the collective term for the various particles suspended in tobacco smoke. The particles contain chemicals, including several cancer-causing substances (carcinogens). Tar is sticky and brown, and stains teeth, fingernails and lung tissue.
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 that transports oxygen molecules around the body. However, carbon monoxide binds to hemoglobin better than oxygen. In response, the body makes more red blood cells to carry the oxygen it needs, but it makes the blood thicker. This means that when the body demands more oxygen during exercise, 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 oxidizing agents.
Oxidizing chemicals – these highly reactive chemicals (which include free radicals) 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 that are known to be carcinogenic.

TIP – If you are struggling to quit smoking, please see your doctor at your local urban health clinic who will put you on the right track to quitting successfully.
