Description

Drug-related violence has become a pressing issue in Western Europe. It is manifested in explosive violence, shootings in the context of organized crime, to homicides committed by neighborhood gangs. This course delves into the multifaceted nature of drug-related violence, exploring its causes, correlates, and policies aimed at addressing it.

Using criminological, sociological, legal, psychological, and public health perspectives, students will examine how international, national and local drug markets are related to violent crime, from local street-level disputes to large-scale conflicts involving organized crime. Students will be introduced to conceptual frameworks through which such violence can be understood, and to state-of-the-art data to monitor drug-related violence. Students will leave with a deeper understanding of one of the most urgent social issues facing Western Europe today.

At the end of this course, students are able to:

  • Critically assess the relationship between drugs and violence;

  • Identify manifestations of drug-related violence in Europe;
