The European Transport Safety Council (ETSC) released a Report concerning Drug Driving in Europe, Policy measures for national and EU action, authored by Laurence Atchison. Driving under the influence of psychoactive drugs leads to deaths and serious injuries on Europe’s roads. Both illicit and licit drugs can disrupt the psychological state of the driver and impair their driving performance. Using multiple drugs simultaneously, or in conjunction with alcohol, increases the risk of a collision even further. This report aims to provide a summary of drug driving across Europe, drawing on the latest research to provide an overview of how drugs affect collision risk and the prevalence of different types of drugs in different road users and regions.
