European Union Research Project Immortal

摘要

This paper presents the results of a prospective case-control study, conducted in the Netherlands, where the prevalence of psychoactive substances among injured drivers (a hospital sample) was compared with the prevalence in the general driving population (a random roadside sample). The study formed part of the European Union (EU) research project IMMORTAL. The aim of the project was "to provide evidence to propose intervention methods for driver impairment, and support the future development of European policy governing driver impairment legislation." Eight drug groups were included in the study: alcohol, BZDs, tricyclic antidepressants, methadone, opiates, amphetamines, cannabis, and cocaine. Among the general driving population, cannabis, BZDs and alcohol were the prevailing substances. Out of the 3,799 stopped and tested drivers: 1.4.5% were positive for cannabis; 3.9% for cannabis alone; and 0.6% for cannabis in combination with other drugs and/or alcohol. 2. 2.1% were positive for BZDs; 2.0% for BZDs alone and 0.1 % for BZDs in combination with other drugs and/or alcohol. 3. 2.1 % were positive for alcohol [blood alcohol content (BAC) ≥ 0.2 g/l]; 1.8% for alcohol alone and 0.3% for alcohol in combination with other drugs.
