The restriction of smoking

Cigarette smoking should be banned from all public places. Smoking is awfully harmful. There is no question about it. It is said that it contains more than four thousands harmful substances such as nicotine, carbon dioxide and so on which induced all sorts of diseases. However, the thing is that secondhand smoking is more dangerous than smoking. Nevertheless, we are still exposed to smoking fumes, and it threatens non smoker's health. On closer investigation, first, exposure by secondhand smoking before and after birth makes them at a risk of abnormal blood pressure, leukemia and a state of disorder. Second, it is a cause of asthma, chronic respiratory symptoms and middle ear infections in children. Third, it increases the risk of lung cancer, heart disease and eye and nasal problem in adults. For me, in my university especially an engineering college, most boy students smoked carelessly in the halls of the building. I had difficulty in breathing. Moreover I am more sensitive than others when it comes to odor, so I got a bad habit that I have hold my breath unconsciously even now. Smokers insist that the tobacco is one kind of their favorite food, so legal sanction could deprive of their liberty, but freedom could guarantee when they do not infringe on others' rights. They have no right to damage other's health. We non smokers have a right not affected by such terrible fumes. Therefore, smoking should be prohibited from all open spaces.
