Smoking in indoor public places including public working places, public transport has been banned(禁止)in China since January 2011.Let’s look at the following advantages of banning smoking.

First, banning smoking will not only help in saving smokers from health problems and diseases, but also be good for passive(被动)smokers. When the smoker is smoking in a restaurant, the people around him are sure to breathe in the smoke and suffer from the diseases . If smoking is banned, spread(传播) of these diseases can be controlled.
Next, banning smoking will put stress on smokers to give up.  Since a smoker is prevented from smoking, he will learn how to live without smoking for long hours. When a smoker doesn’t smell or see anybody around him smoking, it might reduce his wish to smoke too. As a result, people have to give up smoking.
In public places ,smoking influences non-smokers to start smoking, especially adolescents. When teenagers see people around them smoking, they will follow them easily. So a lot of teen smokers will in crease(增加). Also asthma(哮喘)and other problems are often seen in children living around smokers. So if it is banned, these places will become safe for children and teenagers.
Smoking should be banned to increase work productivity(生产率).Workers who smoke usually have a break to smoke while working. So the number of their working hours is smaller.
Smoking should be banned beecause it causes air pollution. If it is banned, it will help keep the environment from getting worse.
