[The new narcotic drug law and its effects on the panorama change of the drug scene of the Aachen border district].

The situation in the region of Aix la Chapelle with its borders towards The Netherlands and Belgium has presented us with increasing problems in drug and narcotic delinquency during recent years. Because of the revised law on narcotic drugs in 1982 and recent decisions by the German Federal Supreme Court, forensic toxicologists are expected not only to define drugs qualitatively as well as quantitatively, but also to provide expertise on problems of effective doses, pharmacokinetics, toxicity and tolerance development with various narcotic drugs. Based on our own experience in this special forensic field, as well as on the data compiled by investigation authorities, our analytical findings are presented with regard to toxicological interpretation and the legal consequences.
