BEIJING, July 3  -- One month after Beijing introduced a tough smoking ban, 40 organizations and 90 individuals have been fined for breaking the regulation, local authorities said Friday.

"The fines totaled about 100,000 yuan (16,120 U. S. dollars)," said Gao Xiaojun, official with Beijing Municipal Commission of Health and Family Planning.

According to Gao, an anti-smoking tip-off hotline has received 3,305 complaints, among which 56 percent were about smoking in office buildings and restaurants.

The ban that has been in effect since June 1, prohibits smoking in all indoor public places, workplaces, and on public transport in Beijing.

Individuals caught smoking may be fined up to 200 yuan, while businesses may have to pay up to 10,000 yuan if they fail to discourage smoking on their premises.

Liu Kaihe, an insurance company employee, said, "I am a frequent guest to hotels. I don't think anyone will bother you if you just shut the door and smoke inside a hotel room."

A restaurant waiter said, "I have met many guests who wanted to smoke in designated rooms when discouraged from smoking in the lobby. Then I had to do some explanation to them."

Li Qiyuan, an employee in a state company, said, some higher-level officials with private offices are still smoking indoors.

"It's like a privilege for them, and who dares to complain about it?" he said, "I think more supervision is needed here."

Vice director of Beijing Health Inspection Institute Wang Benjin said, enforcement of the ban in private offices relies on tip-offs.

"Law enforcement officers will not knock on the doors of private offices for random inspections, but we will look complaints," he said.

Wu Yiqun, vice director of ThinkTank, a Beijing-based anti-smoking advocacy group, said, according to the ban, the legal representatives of organizations and companies should be the chief supervisors of the ban's enforcement in their workplaces.

Liu Qiyuan suggested that the private offices should be equipped with smoke detectors.

Zhang Jianshu, head of Beijing Tobacco Control Association, said, though the ban prohibits cigarette sales within 100 meters of schools, there are still over 1,000 shops selling cigarette in those areas.

Officials of Beijing Administration for Industry and Commerce said, they are negotiating with the city's tobacco monopoly bureau to solve the problem.

Beijing has about 4.19 million smokers. There are only some 1,000 law enforcement personnel for the anti-smoking ban.

Gao Xiaojun said, the city is mobilizing social forces to join the campaign. Beijing Tobacco Control Association is recruiting volunteers to help discourage smoking and explaining the hazards of tobacco in public places.

"The anti-smoking campaign is about changing habit, which requires some time and patience," Gao said.
