Ambroziak K, et al. - Researchers aim at developing a fast and simple liquid chromatography–tandem mass spectrometry screening procedure for detection and identification of synthetic cannabinoids (SCs) in whole blood. They recognize that estimated limits of detection (LODs) make this assay suitable for the analysis of biological material. For more substances, the procedure could be easily expanded. This seems an indispensable advantage in the dynamically developing drug market. In various analytical forensic and clinical laboratories, it can have wide application.
