The authors describe Five Essential Public Health Law Services and suggest investment in the people, methods and tools needed to move major policy initiatives from conception to widespread implementation. The model reflects a transdisciplinary approach integrating public health legal practice with law-related surveillance, evaluation and enforcement functions usually performed by public health practitioners. As an elaboration of law-related activities within the Ten Essential Public Health Services, the framework can be used to define, evaluate and strengthen public health law functions.

Tobacco use remains a leading cause of preventable death in the United States, known to cause cancer and other harmful health conditions, including, but not limited to, respiratory and cardiovascular disease. Implementing evidence-based policies that reduce smoking and tobacco consumption can decrease tobacco-related illnesses and death. One of the most effective strategies to decrease tobacco use is to raise the price of tobacco products, something which state governments can accomplish by establishing specific taxes and pricing limits for tobacco products.
