Smoking

           

            There is a tremendous amount of evidence that various dreadful diseases occur often in smokers than non-smokers and these diseases are: Lung cancer; emphysema causing thinning and weakening of lung tissue; cancer of the mouth, throat, larynx, gullet, bladder, and pancreas; coronary thrombosis causing blockage of arteries to the heart; angina pectoris causing pain due to narrowing of arteries to the heart; and chronic bronchitis with phlegm. Furthermore, Smoking appears to delay the healing of stomach ulcers; it reduces the senses of smell and taste; slows down reflexes which causes making smokers more prone to accidents; and gives the breath, clothes, and homes of smokers an unpleasant smell.

            Very recent research shows that smokers endanger the health of non-smokers. Pregnant women smokers tend to have smaller babies than non-smokers, and their babies are more likely to be born dead or die a few days after birth. Besides such tremendously adverse affects, the children of smoking parents have more lung infections in the first years of life than the children of non-smokers. During one hour in a smoky room, a non-smoker can inhale as much cancer-causing substances as some one smoking 15 filter-tip cigarettes. Illness related to smoking is very expensive.

 In U.K. and USA, it results in the loss of about 50 millions working days a year, treatment costs several hundreds thousands dollar a day, and it causes the death of over a thousand people a week. However, those who give up smoking greatly reduce their chances of developing diseases as mentioned above in question.
