Oral Fluid Screening Devices

Study Overview
=================
Brief Summary
-----------------
This research includes the evaluation of a checklist and on-site screening devices to pre-select drivers suspected of being drug-impaired. The reliability of a limited number of promising on-site screening devices will be investigated. The devices tested will have to be promising regarding both reliability and practicality. In addition to the scientific evaluation of the checklist and the oral fluid screening devices, the time consumption of the selection procedure as a whole (checklist + oral fluid screening) will be evaluated. Outcome of the study will be recommendations for the roadside selection procedure of drivers suspected of drug-related impairment. The recommendations will concentrate on the reliability of the selection procedure. The study is part of an EU project DRUID. Two other countries in Europe take part to this study along with Finland.
