Background: Western Balkan countries exhibit high levels of alcohol consumption, which constitutes a serious public health concern. We aimed to quantitatively assess the influence of the Europeanization process on levels of alcohol consumption in Western Balkans, an issue that has been under-researched. Methods: The process of Europeanization was defined as the penetration of European dimension, procedures, policy paradigms, beliefs and norms in national arenas of politics and policy development. Data about alcohol consumption in six Western Balkan countries from 1991 to 2011 were gathered from the World Bank and World Health Organization databases. Azerbaijan and Georgia were considered control countries. A difference-in-differences approach was used to assess the impact of Europeanization process on levels of alcohol consumption. Results: The Europeanization process impacts alcohol consumption in Western Balkan countries through the European Union directives and tax policies. After starting the Europeanization process, the spirits consumption in Croatia and The Former Yugoslav Republic of Macedonia decreased by 1.06 litter per capita (95% CI: from -1.63 to -0.49) and 1.02 litter per capita in Serbia (95% CI: from -1.9 to -0.1). Conclusion: Our analysis provides useful evidence about the possible influence of Europeanization process especially on spirits consumption levels in Western Balkans. These findings draw attention to the need to implement new policies in order to prevent alcohol health-related harm due to the possible increase of wine and beer consumption.
