Anti-smoking activists want the government to extend its new curbs on smoking to include a ban on lighting up in busy streets. Not content with a ban in restaurants and the declaration of smoke-free zones at beaches and some parks that takes effect on January 1, the campaigners want some streets added to the smoke-free zones. Anthony Hedley, director of the University of Hong Kong's tobacco control research and policy unit, says smoking should also be banned in outdoor shopping arcades because of their restricted nature. Some, but not all, shopping arcades and outdoor covered walkways are smoke-free. The activists want a blanket ban. 'We have a very crowded environment here. On the rare occasion that I get out to window shop, I am just fed up being impacted by other people's cigarette smoke. 'I also have had many people, including people who said they were former smokers, complaining to me about walking behind people who were smoking. I can't think of any justifiable reasons why, in restricted spaces [like overhead walkways and underpasses], people are forced to breathe cigarette smoke.' Professor Hedley added: 'I know that some people would say that this is getting Orwellian and Stalinist-like, and so on, but I feel unrepentant.' He also would like the government to put a stop to advertising of product lines associated with cigarette brands, such as the Marlboro Classics clothing chain. He said they exploited loopholes prohibiting direct cigarette advertising and perpetuated the image that smoking was cool. Medical sector legislator Kwok Ka-ki echoed Professor Hedley's suggestion that the outdoor smoking ban be widened, and suggested tobacco taxes be increased. Only a fraction of the money raised from duty on tobacco products goes towards financing tobacco-control initiatives such as services to help people stop smoking. Dr Kwok wants this to change. He is proposing tobacco producers pay an extra levy equal to 2 per cent of the price of a packet of cigarettes, and that all the proceeds be used to finance tobacco control. Dr Kwok also believes the rate of duty payable on tobacco products - currently 53.3 per cent - should be increased since it has not gone up since 2001. He said he plans to move a motion for debate in the Legislative Council asking the government to introduce such a levy.
