Tobacco Cigarette poisons Tobacco contains many different substances including nicotine, tar and carbon monoxide.smoke particles Lung diseases A smoker get lung infections. In the bronchitis, the smokers bronchi inflames. Lots of mucus is produced. This can cause excessive coughing. The air sacs lose stretchiness. It is difficult to get oxygen into the blood. This is called emphysema. Someone with this condition may have to breathe oxygen from a cylinder. Nicotine- affects the brain. It is addictive. Tar – is a poison that causes cancer. Its a carcinogen. Cigarette smoke often causes lung cancer, but can risk development of other cancers. Carbon monoxide- takes the place of oxygen in red blood cells, so the blood carries less oxygen. This can harm body cells. In pregnant women this can be dangerous as the baby will get less oxygen, it may not grow properly and have a low birth weight. A person who smokes is likely to have heart disease. Smoke particles – burnt fragments of tobacco Accumulate in the lung tissue and stimulate body’s defence system to remove them.
