     A ban on smoking in public places has come into effect on May 1,2011 in China-home to one third of

the world's smokers.

     The ban is aimed at controlling the number of deaths from smoking-related diseases, running at a

million deaths a year. That figure is predicted to double by 2020. The new smoking ban is an attempt to

prevent that prediction coming true.

     The new rules forbid people from smoking in places like hotels, railway stations or theatres, but not

including the office. Employers can warn their staff of the dangers of smoking but cannot forbid them from smoking at their desks.

     But the new rules have been criticized because they do not describe in detail the punishments for

businesses or individuals who flout them. Quite many smokers do not seem to take much notice of them.

Often you find people smoking at next table while you are eating your meal or having a drink in a bar. In

bus stops as well as in railway stations smoking can also be seen here and there. Business owners are also angry at the efforts to force them to ban smoking on their premises (经营场所), because many customers refuse to go to restaurants or places of entertainment where smoking is forbidden.

     It appears that many Chinese people are unaware of the dangers of smoking. Research suggests that

only one in four knows the harm cigarettes can cause. Officials say they have to try to persuade people

not to smoke to try to reduce the numbers dying from smoking-related diseases. At the same time,

however, the local governments make a lot of money from the sales of cigarettes by the state-owned firm

that makes and sells tobacco products throughout the country.
