THE DANGERS OF SMOKING

A smoker can easily be identified in any group. Not only does he reek of stale smoke,he also has bad breath,much to the dread of non-smokers.However, the effects of smoking are far more insidious than the offensive smell associated with smokers.
Cigarette smoke contains many toxic substances like carbon monoxide,nicotine and carcinogens that not only cause irreparable damage to the smoker,but also to those around him who inhale the smoke.
Carbon monoxide reduces blood capacity to carry oxygen,thus causing fatigue and painting even with the slightest physical exertion.The lack of oxygen in the body acts as a catalyst that accelerates the aging process,causing wrinkles.
Nicotine contained in cigarette smoke reduces the activity of the brain and nervous system.It also raises the risk of high blood pressure.Nicotine causes the contraction of blood vessels and decrease of blood supply. This ultimately leads to heart attacks.
Smokers are at a higher risk of developing certain kinds of cancers because cigarette smoke contains carcinogens.Long-time smokers often develop cancers of the mouth,larynx and lungs.
Smoking not only endangers the smoker himself but also those who inhale secondary smoke-smoke exhaled by smokers. In view of the many dangers of smoking,more smoking cessation programmes should be introduced to smokers.
