Análisis de drogas de abuso en tejido capilar: revisión normativa y relevancia como evidencia en peritajes forenses
Abstract
Hair analysis for drugs of abuse has gained importance in forensic science due to its ability to detect both recent and chronic use of psychoactive substances. Unlike blood or urine, hair retains toxins and metabolites over time, making it a useful tool for investigations seeking to identify patterns of prolonged use. In this regard, the most accurate and effective techniques are liquid chromatography coupled with mass spectrometry and gas chromatography; however, these require specialized equipment and more time to obtain results. Therefore, in the legal field, it is crucial that these analyses be performed following international quality standards, such as those established by ISO/IEC 17025, and that a proper chain of custody of the samples is guaranteed.
