Tobacco is said to contain about 4,000 dangerous chemicals that can cause diseases. Significantly, the intake of nicotine is very unfriendly to human health. Smokers, active, passive and second hand , suffer from many diseases such as Emphysema, lung cancer, chronic to acute bronchitis, diseases of the oesophagus, mouth ulcers, bad breath, bad eyesight and at times results in women delivering underweight babies. Other diseases smoking can cause include hypertension and heart palpitation. Smoking can also make people look older than their ages a situation caused by Hypoxia.
Hypoxia is the loosing of oxygen content in organs, resulting in wrinkles.
Apart from these frightening effects, smokers are also at risk of acquiring Ischaemic heart disease, sudden death, heart attacks, chronic obstructive lung disease, and a situation which impairs proper blood flow. It is equally frightening to know that non-smokers who inhale the smoke of cigarettes others smoke are equally at risk. Considering the role tobacco plays in most economies, apart from creating employment, there has been some amount of difficulty in writing off the tobacco industry. The figures, when they are seen as frightening, would at least scare tobacco users and gradually reduce or clear the air. For those already affected by tobacco usage, their appeal goes to cigarette manufacturers to support chest clinics with part of their profits as is done in the United States, where profits from cigarette producers are used for research at chest clinics.
