Heroin and injecting drug use

The regular and sustained use of heroin, drug injecting and, in some countries, the intensive use of stimulants account for a substantial proportion of drug-related health and social problems in Europe. The number of individuals exhibiting this kind of behaviour is low relative to the population overall, but the impact of problem drug use is considerable. To help understand the scale of this problem and to allow trends to be monitored over time, the EMCDDA is working with the Member States to redefine the concept of ‘problem drug use’ and to develop strategies to measure both its scale and its impact.
