'Smoking is injurious to health'. This is printed on all cigarette packing boxes. Every smoker will see and read this. In all the cinema halls they are showing the ill effects of smoking. But how many smokers are giving up smoking? 
It is true that many great people also have this habit. They feel relieved by smoking. But they don't understand they are spoiling the health of others. I heard some people saying that without smoking they can't start any work. Some people say they will get new ideas if they have a smoke. I don't understand how far it is true. There are many other ways to get your mind fresh. But nobody has right to spoil the fellow human beings by leaving nicotine into the atmosphere. Addiction may be psychological, but it is true they are creating a problem to the environment
