The present study from 2002 includes medicolegally examined fatal poisonings among drug addicts in the five Nordic countries: Denmark, Finland, Iceland, Norway and Sweden. A common definition "drug addict" is applied by the participating countries. The number of deaths, age, sex, place of death, main intoxicant and other drugs present in the blood are recorded in order to obtain national data, as well as comparable Nordic data and data comparable to earlier studies from 1997 and 1991. The Icelandic results are commented on separately due to the low number of cases. The most fatal overdoses are seen in Norway, in both the death rate (number per 100,000 inhabitants=8.44) and in absolute number (n=232). The comparable figures for the other four countries are Denmark 5.43 (n=175), Iceland 3.6 (n=6), Finland 2.93 (n=94) and Sweden 2.56 (n=136). In earlier studies from 1991 and 1997, the highest death rate is seen in Denmark, with Norway as number two. Denmark is the only country where the death rate decreases from 1997 to 2002. A relatively large increase in deaths in the younger age groups (
