[Evaluation of the usefulness of thin-layer chromatography and orientation tests detecting various addictive drugs in biological specimens].

Abuse of medicines and alcohol pose particular problems with those carrying out professional work involving movement (drivers, crane operators etc.). Most accidents are caused by ethyl alcohol, however, other substances cannot be excluded, either. This paper has been aimed at the verification of the efficiency of thin-layer chromatography and tests applied in toxicological analyses of acute poisonings in the detection of lower concentrations of certain addictive medicines. The studies were carried out on biological material (urine) of subjects who had been given, for therapeutic purposes, increased doses of medicines. The group involved 156 patients from I Clinic of Psychiatry, Medical Academy of Lódź, and the Department of Disaccustoming and Psychiatry in Zgierz.
