Drug addicts who had died in Copenhagen City and County in 1981 and 1989 were analysed for methadone. In 1981, 94 cases were analysed of which 16% were found positive for methadone, and in 1989, 70 cases were analysed of which 37% were positive. Methadone alone was found to be the cause of death in 50% more cases in 1989 than in 1981. ⋯ Alcohol was found in only about 30% of the methadone-positive cases. The median whole blood concentrations of methadone found in addicts where methadone was the cause of death was 0.3 mg/kg where no alcohol was present and 0.2 mg/kg where alcohol was present. In living persons using methadone, the median was 0.1 mg methadone/kg whole blood with or without alcohol present.

Cases of fatal poisoning among drug addicts examined at the institutes of forensic medicine in Aarhus, Denmark (n = 238) and Oslo, Norway (n = 263) are compared and discussed on the basis of the availability of illicit and medical drugs during the 1980s. The annual number of deaths among drug addicts in age groups over 30 years increased, but there was no increase in the number of deaths among younger drug addicts in either country. More than 80% of the drug addicts in both samples were men. ⋯ The registered medical drugs propoxyphene, methadone and ketobemidone accounted for half of the Danish cases but only a small number of the Norwegian cases. Amphetamine caused few deaths in either country. Alcohol and benzodiazepines were present in more than one-third of the cases in both countries, indicating frequent use of these substances.

In a case of suicide in a depressive 19-year-old man with considerable ingestion of new leaves, resorption of yew ingredients could be demonstrated. The main substance could be identified as 3,5-dimethoxyphenol, the aglycone of taxicatine, which is a typical ingredient of yew leaves. 3,5-dimethoxyphenol was demonstrated in harvested yew leaves, stomach content and cardiac blood of the victim. ⋯ The components detected by TLC have not yet been identified. The results demonstrate that 3,5-dimethoxyphenol can be used as a marker in cases of intoxication by yew ingredients.
