Driving under the influence of drugs (DUID) is a worldwide problem. Several countries have adopted DUID legislations which prove their deterrent effect and impact on road safety. However, the use of new psychoactive substances (NPS) and prescription drugs is not known, as the applied roadside screening tests have not yet been adapted for these compounds. In this study, 558 blood samples...
One of the main challenges posed by the emergence of new psychoactive substances is their identification in human biological samples. Trying to detect the parent drug could lead to false‐negative results when the delay between consumption and sampling has been too long. The identification of their metabolites could then improve their detection window in biological matrices. Oxidative metabolism...
