The aim of this study was to develop a quantitative gas chromatography mass spectrometry (GC-MS) method to determine the classical amphetamines and their methylenedioxylated derivatives in human hair. The procedure involved liquid-liquid extraction of hydrolysed hair spiked with deuterated internal standards and direct derivatization with perfluorooctanoyl chloride. After evaporation of the...
