The aim of this study is to get new information on the whole blood-plasma-oral fluid ratios of psychoactive drugs which are encountered in traffic.
Samples are taken from drivers suspected of being under the influence of drugs or medicines. The samples are analysed with immunological methods and GC-MS.
Observations from Police and a physician on impairment are combined with the results of the different bodily fluids. Observational evaluations and substance concentrations are compared.
