　　Study Says Smoking Bans Do Not Hurt Jobs in Bars, Restaurants

　　This is the VOA Special English Health Report.

　　Smoking is the world's leading preventable cause of death. In the United States, smoking rates are down from the past, but cigarettes still cause about one-fifth of all deaths.

　　Nonsmokersare also affected. Thousands in the United States die each year from heart disease and lung cancer from breathing other people's tobacco smoke. Secondhand smoke also causes breathing infections in young children. It can even cause sudden death in babies.

　　In recent years there has been a strong push for local and state governments to ban public smoking. The American Lung Association says half of the fifty states have passed smoke-free laws. Some measures are weaker than others. But many are comprehensive bans -- they include restaurants and bars as well as other workplaces.

　　Wisconsin and North Carolina both approved smoking bans on the same day this month. Wisconsin passed a comprehensive ban that will take effect in July of next year.
