[Deaths among drug addicts in Eastern Denmark 2005]

The purpose of this study was to investigate deaths among drug addicts in Eastern Denmark in 2005, partly fatal poisonings, partly deaths where the cause of death not was a poisoning and to compare the results with those reported in studies from 1991, 1997 and 2002.

All deaths among drug addicts investigated at the Institute of Forensic Medicine in Copenhagen.

The number of deaths among drug addicts was 160 of which 64% were due to fatal poisoning. The number of drug addict deaths has remained almost constant in the period 1991-2005, but in 2002 and 2005 a decrease of about 10% was seen in the fraction of fatal poisonings. As in 2002, a decrease in the fraction of heroin/morphine poisonings was seen, and an increase in the fraction of methadone poisonings with a proportion of heroin/morphine poisonings of 17% and a proportion of methadone poisonings of 39%. As in the previous studies, the most commonly detected drugs were methadone, heroin/morphine, benzodiazepines and cannabis and, as in 2002, methadone was more frequently detected than heroin/morphine. In the non-poisoning deaths, the most frequent manner of death was natural death (44%). In 12% the manner of the death was suicide, in 14% death was accidental, in 4% homicide was the manner of death and in 26% the manner of death was undetermined.

The increase in the number of fatal poisonings with methadone and the decrease in the number of fatal poisonings with heroin/morphine seen in the 2002 study continued in 2005. The poly-drug use had increased in 2005 with more drugs detected in each case than before.
