On-site testing for drugs of abuse : methodology, first results and experiences of the police (WP4 of the ROSITA project).

In the context of the European project ROSITA, the Institute of Legal Medicine Homburg/Saar is co-operating with the traffic police of Saarland, a federal state of Germany, in order to assess different roadside drug tests for their functionality and reliability in traffic controls, and for their analytical force of evidence. Apart from the explanation of the control policy of the traffic police to check for DUID (including the control systems, how to gain evidence for actual drug use, usual signs of impairment and behaviour etc.), we would like to present the so far tested versions of devices in the Saarland within the project ROSITA, the tested numbers of samples, arisen problems and the analytical results.
