A law that is poorly defined can be self-defeating. Hong Kong’s liquor laws prohibit bars, clubs and other licensed venues from selling alcohol to those under the age of 18, a socially responsible restriction that reflects community standards and expectations, but they do not apply to retailers such as supermarkets and convenience stores. The sales policies of these businesses are governed by their owners and managers’ sense of responsibility. Where it is lacking, they can claim to have done nothing wrong in selling alcohol to under-18s.

Despite the law’s good intention, teenagers and even younger children can be seen openly drinking in public spaces. Evidence is mounting in tandem with fears for health and social consequences. In October we reported a survey by Polytechnic University’s School of Nursing that found 38 per cent of the 840 Form Three students from six secondary schools interviewed had drinking experience dating back on average to just under 11 years of age. The survey found young drinkers were nearly five times more likely to develop behavioural problems.
