Notes:

Absolute numbers from different countries are not directly comparable since differences remain in case definition and recording methods

The national definitions used to report to the EMCDDA and the methods used are described in Drug related deaths – methods and definitions.

National definitions usually refer to acute deaths directly related to drug consumption (‘overdoses’, ‘poisonings’ or ‘drug-induced’). Note that, in a few countries, the figures also include a limited number of cases of deaths indirectly related to drug use (e.g. AIDS, accidents with positive toxicology). See Drug related deaths – methods and definitions with national definitions. Note in addition that in some countries, statistics published at national level may differ from those presented here as a result of differences in case definition used at national level.

(1) Data refers to the five major cities: Madrid, Barcelona, Valencia, Zaragoza and Bilbao.
