Smoking, which may be a pleasure for some people, is a series of discomforts for their fellows. Medical scientists have expressed their concern about the effect of smoking on the health not only of those who are smoking but also of those who live in the air polluted by tobacco smoke. And studies show that non-smokers suffer more than the smokers themselves. Nowadays many countries in the world have passed laws to ban smoking in public places, A great number of students have joined in trying to persuade the school to forbid smoking. Smoking has been not allowed in theatres, cinemas and in other public places. Therefore, smoking must be forbidden in our classrooms.
Fortunately ,Beijing has imposed a total smoking ban, Citizens was forbidden to smoke in Beijing. I believe that this ban was significant.it will lead to the decrement of the student smoking rate 。And the health condition of all the people will be greatly improved.
