Review de un método para la determinación de cocaína en matriz biológica (pelo), por cromatografía de gases-espectrometría de masas gcms

Abstract

Abstract:For the determination of the use of cocaine, information is reviewed and analyzed with the purpose of establishing cocaine consumption in hair, by means of Gas Chromatography-Mass Spectrometry, GC/MS, in very long periods of time ranging from weeks up to years, depending on the length of the hair, to check the chronicity of the use of the drug or perform a retrospective analysis of consumption. In addition to confirming a drug addiction, the standard gold method can also be applied to pubic hair, underarm, legs, chest or back. This method helps to differentiate if a person is a drug user or drug dealer. The results obtained in this investigation would not be binding with legal processes of defendants, being able to be used in the future, in any judicial process. It is important to highlight, in Ecuador, the lack of an adequate method to detect the drug retrospectively and differentiate drug traffickers from consumers, since the common biological matrices, such as blood and urine, unlike hair, offer only a limited range of time to detect drug.
