Abstract
Trends towards harmonisation and free trade are outlined. The direct impact that integration and harmonisation can have on alcohol, drugs and traffic safety is to reduce the sovereignty of counties over their use of taxation, regulation and other control mechanisms for health and safety. Some specific issues and examples are discussed. The fundamental principle underlying free trade, of raising the consumption of private goods, is at the crux of concerns regarding alcohol, drugs and transport. Any policy or regulatory change that would increase alcohol or drug consumption could affect traffic safety. In addition any change that would reduce vehicle or roadway standards or increase mobility could similarly affect traffic safety.
