Deaths among drug addicts in Denmark in 1968-1986.

In the period 1968-1986 a total of 1618 fatalities among drug addicts were investigated at the three University Institutes of Forensic Medicine in Denmark. The annual number rose from 5 in 1968 to 163 in 1980, thereafter there has been a gradual fall to 121 in 1986. About 80% were males. The average age has risen from 22/23 years in the early 1970s to 31 years in 1986, and the percentage of addicts with a duration of abuse more than 10 years has increased gradually; both facts indicate a decrease in the recruitment among the quite young. In the whole period morphine was abused, supplemented by various medicines. Amphetamine was abused in the first years and again in 1986. The percentages of addicts with an abuse of alcohol and of addicts dying after a period of abstinence lasting more than 1 year, respectively, have increased. No essential changes were observed regarding distribution of residence or of the cause and manner of death. In the poisoning cases the predominant drug of poisoning was morphine/heroin, in all the years constituting approx. 30-50%. The second most frequent drugs of poisoning in the first half of the period was barbiturate, in the last half dextropropoxyphene and methadone. Only very few cases dying of cocaine poisoning were present and deaths due to so-called designer drugs have not been observed.
