The main objectives of this study were to develop a method for the measurement of cocaine derivatives in oral fluid by coupling a probe electrospray ionization (PESI) source with quadrupole time-of-flight (QTOF). The three cocaine derivatives considered were: benzoylecgonine (BZE), cocaine, and ecgonine-methylester (EME).
