Cigarette smoke contains about 4,000 different chemicals which can damage the cells and systems of the human body. These include at least 80 chemicals that can cause cancer (including tar, arsenic, benzene, cadmium and formaldehyde) nicotine (a highly addictive chemical which hooks a smoker into their habit) and hundreds of other poisons such as cyanide, carbon monoxide and ammonia.
Every time a smoker inhales, these chemicals are drawn into the body where they interfere with cell function and cause problems ranging from cell death to genetic changes which lead to cancer.
This is why tobacco smoking is a known or probable cause of approximately 25 diseases. According to WHO figures, smoking is responsible for approximately five million deaths worldwide every year. However it also contributes to, or aggravates many other diseases and may play a part in many more deaths. Even the WHO says that its impact on world health isn’t fully assessed.
WHO says smoking is a greater cause of death and disability than any single disease. By 2020, the WHO expects the worldwide death toll to reach 10 million, causing 17.7 per cent of all deaths in developed countries.
There are believed to be 1.1 billion smokers in the world, 800 million of them in developing countries.
