Forensic methods and tests to determine cannabinoids bibliographic review

Abstract

The bibliographic review is of a narrative nature of the current literature on forensic methods and tests for the determination of cannabinoids, the main research objective being to provide suitable forensic instrumental methods and techniques for the analysis of these metabolites, the sources used have been located by Internet search engines, using databases such as: PubMed-Medline, Scielo and Lilacs. For the optimal article search system, the update of these data not older than 5 years, from its publication date, and its content is closely related to the subject, was taken into account. Because cannabinoids are highly retained in the body's tissues, they can be detected in urine for days or weeks after consumption, which depends on the quantity, route of entry, and frequency, with the biomarker being 11-nor-9-carboxy-tetrahydrocannabinol. commonly found in the sample by specific methods and techniques. The immunoassay test, thin layer chromatography and infrared spectroscopy are qualitative tests commonly used to determine the metabolite, however, high resolution gas and liquid chromatography and these techniques coupled with mass spectrometry are those that provide us with greater reliability and accuracy of the results.
