My view on smoking

Nowadays,cigarette smoking has become a widespread habit all over the world.It was reported that smokers make up one quarter of the world population.In China,33.9% above the age of 15 are smokers.
Although an increasing number of people have realized that smoking can do great harm to people's health,some people still enjoy smoking.They argue that it is a kind of fashion and can refresh themselves.In fact,needless to say, the disadvantages of smoking outweigh the advantages.As we all know,the mixture of nicotine and carbon monoxide in each cigarette you smoke temporarily increase your heart rate and blood pressure,thus straining your heart and blood vessels.Worse still,if you keep smoking for a long time,your airways swell up and let less air into your lungs,and you are much given to be exposed to emphysema which is an illness that slowly rots your lungs. Besides, according to some scientific statistics,men who smoke are more likely to die from lung cancer than non-smokers.Heart diseases and strokes are also more common among smokers than non-smokers.Last but not least,smoking is not only harmful to smokers themselves,but also a threat to public health,especially to women and children.
Based on the analysis,the conclusion can be arrived at that we must try our best to get rid of smoking especially in public in that not only can the smokers themselves become healthier and stronger,but people around them can be more unlikely to be the victims of second-hand smokers
