Non-communicable diseases, associated with risk factors such as tobacco consumption, poor diet and alcohol use, represent a growing health burden around the world. The seriousness of non-communicable diseases is reflected in the adoption of international instruments such as the WHO Framework Convention on Tobacco Control; the WHO Global Strategy on Diet, Physical Activity and Health; and the WHO Global Strategy to Reduce the Harmful Use of Alcohol. In line with these instruments, states are beginning to use measures such as taxes, restrictions on marketing, product regulation and labeling measures for public health purposes. This book examines the extent to which the law of the World Trade Organization restricts domestic implementation of these types of measures. The relationship between international health instruments and the WTO Agreement is examined, as are the WTO covered agreements themselves.
