In the area of communications law, regulation of advertising has always been one of the most complicated issues. Among them, tobacco advertising is perhaps the most controversial topic. This study focuses on the regulation of tobacco indirect advertising by comparing laws of some selected countries and the FCTC (Framework Convention on Tobacco Control). By examining WHO's FCTC, the laws of European Union, United Kingdom, Finland, Norway, United States, Canada, Singapore, Thailand, South Korea, Japan, Australia, and New Zealand, the author concludes that a comprehensive ban on tobacco advertising, especially in tobacco indirect advertising, is constitutionally sound and compatible with international trend. This should provide certain valuable suggestion to Taiwan's present legislative and enforcement works.
