title: Narcotics at street level in Denmark. A prospective investigation from 1995 to 2000.
abstract: This article describes an investigation of illicit drugs at street level in six selected police districts in different regions of Denmark. The investigation was carried out during a 6-year period from 1995 to 2000. During the period, a total of 1244 samples were examined, as about 200 samples were seized each year. A total of 94% of the seized samples were familiar drugs: heroin base, heroin hydrochloride, cocaine hydrochloride and amphetamine sulphate. Only 2% of the samples contained designer drugs. From having constituted 53% of the samples in 1995, the frequency of heroin base fell during the period to 27% of the samples in 2000. The frequency of heroin hydrochloride was unchanged. In the same period, the frequency of cocaine hydrochloride increased from 10% of the samples in 1995 to about 25% of the samples in 2000. Apart from a few exceptions, cocaine had the same extension in all regions of Denmark after 1996. Amphetamine was more frequent in the west of Denmark, while heroin hydrochloride was more frequent in central Denmark. The purity of heroin base was lower in the period 1997-1999 than in the other years. During the entire period, the purity of cocaine hydrochloride and amphetamine sulphate fell, while the purity of heroin hydrochloride was unchanged. No significant differences between the various regions of Denmark were detected during the period in the purity of heroin hydrochloride, heroin base, cocaine hydrochloride or amphetamine sulphate. MDMA was the most frequent designer drug, but other types of designer drugs such as MDA and MDE and the less common PMA, PMMA and MBDB were also found.
