Abstract

Driving under the influence of drugs can affect the driving ability. This dissertation studies the interface between road safety and the use of ecstasy and cannabis. THC (the active substance in cannabis) in the form of pills and the combination of lack of sleep and ecstasy appeared to negatively influence the driving ability. The ‘Standardized Field Sobriety Tests’ that are used on the roadside in North America to show decreased driving ability as a result of alcohol use, turned out insensitive to this form of THC. Saliva testing appeared not 100% suitable for reliable detection of THC, but this method has strongly improved over the last few years and appears promising for the screening of drivers for drug use.
