Simultaneous detection of 93 conventional and emerging drugs of abuse and their metabolites in urine by UHPLC-MS/MS.

Novel psychoactive substances (NPS) are becoming increasingly popular worldwide in recent years, some of which have been reported to cause considerable harm and even fatalities. Currently, simultaneous screening for a comprehensive panel of conventional and novel drugs of abuse is not widely available in most clinical laboratories. The aim of this study was to establish a chromatography/mass spectrometry-based analytical system for the simultaneous detection of conventional drugs of abuse and NPS in urine.
