[Drug and narcotic use among Danish drivers].

An investigation was made of the presence of drugs and narcotics in samples from Danish drivers having violated the Danish Road Traffic act in 1993. Four hundred and twenty-five cases were received, but only 317 cases were analysed for drugs or narcotics. In 256 cases drugs or narcotics were found present with a total of 531 findings. In 112 of the cases only one compound was found present. Benzodiazepines, morphine, methadone, cannabinoids and amphetamine were the most frequently occurring compounds with 239, 52, 42, 32 and 28 findings, respectively. The study has shown that especially the benzodiazepines together with the illicit drugs seem to constitute a threat to traffic safety. For two countries very much alike, namely Denmark and Norway this study has shown a remarkable difference in the number of samples analysed and the results found.
