Secondhand smoke hits clubs, bars the hardest

Survey findings come as Beijing prepares to launch toughest tobacco control measures yet

Customers and staff members in Beijing's bars and nightclubs are exposed to the most secondhand smoke in the city, according to a survey by health authorities.

The survey, conducted by the Beijing Center for Disease Control and Prevention and Capital Medical University, was based on inspections of more than 2,500 public places and on questionnaires collected last year from more than 8,000 people in the capital.
