The amphetamine abuse is a preoccupation of public health authorities all over the world. In Brazil, anoretic drugs like fenproporex have been much used. Fenproporex is metabolically dealkylated to amphetamine in the human body. In spite of its legal control, it has been abused in the country. Different samples have been used to identify the drug in toxicological analyses. Hair samples have been proposed recently to identify and study the long-term use of the drug. CG-MG is the technique used to identify amphetamines in hair samples. Following a method proposed in specific literature, some studies have been developed to evaluate the application of the fluorescence polarization imunoassay (FPIA) to identify amphetamine in hair samples of fenproporex users. The results show that the standard method may be used as screening in the identification of amphetamine by FPIA in hair samples of fenproporex users.
