Illegal drug market is one of the largest and most profitable markets in the world, as well as in Europe. Generally, crime associated with drug abuse is a large and complex area that manifests itself through primary, secondary and tertiary criminality. In various modalities of this area, there is also drug trafficking. The aim of this graduation is to get acquainted with the structure and dynamics of the contemporary drug market in Europe and compare whether the same image is reflected in the Republic of Croatia. The concept of a drug market today is difficult to define because of the process of globalization and the development of new technologies, it has become dynamic and changeable. But some facts about the European drug market throughout the years are still ongoing. One of the facts is that Europe is at the center of the east and west, making it an unavoidable continent and passing through it already well-known but also some new alternative routes of drug trafficking. Throughout the years, it is a constant fact that the groups of organized crime are major actors in this area acting locally and internationally. As far as drug supply and demand is concerned, a wide range of drugs is available on the European market: the most common cannabis, followed by cocaine, amphetamine, heroin and MDMA. The same situation has also been noted in the Republic of Croatia. As the two main challenges facing European countries, but also in Croatia are: new psychoactive substances, which are growing repeatedly year after year, and the rapid growth of the Internet drug market. Based on a review of recent literature, the graduation emphasizes the main facts and problems in the European drug market, which may be an incentive for policy makers to actively follow new drug market trends, as well as help in developing guidelines in fighting drug abuse.
