A number of new designer benzodiazepines have reached the illegal drug market over the past years. Toxicological interpretation of concentrations of these drugs in blood is quite challenging as very limited human data have previously been published. The aim of this study was to report blood concentrations of new designer benzodiazepines in a population of drugged drivers as well as some other criminal offenders, and to relate this to clinical impairment. ⋯ Given the lack of previously published data on human concentrations, results presented in this study could be helpful in interpretation of blood concentrations of new designer benzodiazepines. This is crucial for the assessment of the importance of toxicological results in suspected drugged drivers, rape victims, etc.
