 Study developed a measurement tool to assess stringency and on the ground impact of four key alcohol policy domains. Data on availability, pricing policy, alcohol marketing, drink driving were used to create an alcohol policy index. Countries in which more modes of alcohol marketing are legally allowed had higher APC. Legislation on outlet density and drink driving predicted APC, whereas trading hours did not.
