A validated method for the simultaneous analysis of multiple hallucinogens, chlorpheniramine, ketamine, ritalinic acid, and several metabolites is presented. The procedure comprises a sample clean-up step, using mixed-mode solid-phase extraction followed by liquid chromatography (LC)-tandem mass spectrometry analysis. Chromatographic separation was achieved using a Sunfire C(8) column eluted...
