Resumen
Cocaine is usually seized mixed with a wide variety of adulterants such as benzocaine, lidocaine, caffeine, and procaine. The forensic identification of cocaine in these street drug mixtures is normally performed using colorimetric testing kits, but these tests may suffer from interferences, producing false-positive results. Here, we describe the use of analytical techniques including attenuated total reflection Fourier transform infrared (ATRFTIR) and ultraviolet-visible (UV-VIS) spectroscopies to distinguish between cocaine and other adulterants (lidocaine, promethazine, powdered milk and yeast) that yield positive results on the Scott test using the thiocyanate cobalt reagent. A further 13 substances were also analyzed using the Scott test. 37 9 1538 1544 De Simões, C.M.O., (2003) Farmacognosia: Da Planta ao Medicamento, , 5th ed., Editora da UFSC: Porto Alegre Passagli, M., (2009) Toxicologia Forense: Teoria e Prética, , 2th ed., Millennium Editora: Campinas Romão, W., Schwab, N.V., Bueno, M.I.M.S., Sparrapan, R., Eberlin, M.N., Martyni, A., Sabino, B.D., Maldaner, A.O., (2011) Quim.
