   Advertisements of tobacco and those of“smoking is harmful”are often seentogether. But there has been an on-going argument about whether or not tobacco should be forbidden and made illegal. I have always believed that smoking should be illegal for the following reasons.

　　First, smoking does great harm to human health and causes many diseases. It is reported that more than 70% of lung cancer sufferers are smokers, andthe average life-span of smokers is seven years less than that of non-smokers. Moreover, it hurts not only smokers, but also the ones around the smokers. Many researchers claim that breathing“second-hand smoke”maybe even more harmful than smoking.
