This article was elaborated with searches in scientific publications, bibliographical reviews, scientific journals and Forensic Science books, as well as other sources of scientific knowledge. There are currently many techniques used in the routine of Forensic Toxicology laboratories, among which the use of the following are most frequently used: Thin Layer Chromatography - CCD, Immunoassay methods, High Performance Liquid Chromatography - HPLC, Gas Chromatography - GC and Liquid or Gas Chromatography Coupled to Mass Spectrophotometry - HPLC/ MS.
