Smoking is widespread habit
even among teenage students. The number of young smokers are increasing. It is
estimated that over 10% of the senior high school students have tried smoking
once or more and some of them even steal money from their parent to buy
cigarettes, that is terrible.
As it is known to all, smoking
is harmful for health. And it's even more harmful to teenage students for it
does greatly harm not only to their health but also to their mind.
Teenage students are future
builders of the country. They should spend their time learn what is useful but
keep a healthy lifestyle as well. So it's high time that teenage smokers make
up their minds to give up smoking.
