The global epidemiology of tobacco and related chronic diseases.

A new paradigm is needed for the epidemics of the 21st century. The tobacco epidemic has shown that the curative-based medical model is insufficient to reduce the use of tobacco, and that this will only be achieved by prevention and public health measures. The magnitude of the health risks and the economic factors can only lead to one conclusion: there needs to be hard-hitting, well-funded campaigns in all countries and at all levels to avert initiation, decrease consumption, assist with cessation, and protect non-smokers. We must embrace the spirit of the Framework Convention on Tobacco Control by implementing robust, effective, cost-effective measures to protect people's health and the wealth of nations. We stand at a critical juncture in the unfolding pandemic.
