Epidemiology of binge drinking
Concerns over binge drinking by teenagers has led to a review of liquor advertising being announced by the New Zealand government in January 2006. The review considered regulation of sport sponsorship by liquor companies, which at present is commonplace. Previously the drinking age in New Zealand was 20, then dropped to 18 in 1999.
Alcoholism in adolescence
A legal minimum age for the buying or consuming of alcohol is in place in many of the world's countries, typically with the intent to protect the young from alcohol-related harm. This age varies between countries; for example, the minimum legal drinking age for Australia is 18, whereas the MLDA in the United States is 21.
