Organised crime is changing and becoming increasingly diverse in its methods, group structures and impact on society. This article aims to research, on the one hand, the impact of organized crime on state’s economy, on the other hand – to analyse the possible legal and economic measures tackling and preventing organized crime activities. The article contains results of the analysis of international, regional and national legal acts and the secondary analysis of statistical data of European Union agencies and international organizations. The author used a variety of methods: from selection and analysis of primary and secondary sources to descriptive, comparative and synthesis methods. Such analysis required multitudinous, broad and diverse base of empirical data, which were collected from the international, regional, national organizations and agencies, as well as scientific, operational and theoretical reports related to the issue of organised crime and impact of this phenomenon to the state and the society.
