“…ICP-MS has been used to examine cocaine seizures from three different areas in a small state in Brazil. Both ICP-MS and inductively coupled plasma–optical emission spectrometry (ICP-OES) were used to detect and quantify diverse elements in cocaine samples, mainly Al, Ca, Cu, Fe, Mn, Mg, Zn, Mo, Co, Pb, and PP [ 43 ]. Cocaine samples had homogenous inorganic profiles and similar concentrations, mainly due to geographic proximity [ 43 ].…”

In forensic chemistry, when investigating seized illicit drugs, the profiling or chemical fingerprinting of drugs is considered fundamental. This involves the identification, quantitation and categorization of drug samples into groups, providing investigative leads such as a common or different origin of seized samples. Further goals of drug profiling include the elucidation of synthetic pathways, identification of adulterants and impurities, as well as identification of a drug’s geographic origin, specifically for plant-derived exhibits. The aim of this state-of-art-review is to present the traditional and advanced analytical approaches commonly followed by forensic chemists worldwide for illicit drug profiling. We discussed numerous methodologies for the physical and chemical profiling of organic and inorganic impurities found in illicit drug. Applications of powerful spectroscopic and chromatographic tools for illicit drug profiling including isotope-Ratio mass spectrometry (IRMS), gas chromatography–mass spectrometry (GC-MS), gas chromatography–isotope ratio mass spectrometry (GC-IRMS), ultra-high-performance liquid chromatography (UHPLC), thin layer chromatography (TLC), liquid chromatography–mass spectrometry (LC-MS) and inductively coupled plasma-mass spectrometry (ICP-MS) were discussed. Altogether, the techniques covered in this paper to profile seized illicit drugs could aid forensic chemists in selecting and applying a suitable method to extract valuable profiling data.

“…Amorim et al (2021) determined inorganic adulterants in cocaine samples collected from the streets of Espirito Santo. Some samples revealed high concentrations of Al, Ca, Fe, Mg, Mn, and P, indicating adulterants such as gypsum, marble powder, limestone, cement, and others used to increase pro ts in the illegal market(Amorim et al 2021). Other studies have also been conducted on the composition and identi cation of other drugs such as hashish(Souza et al.…”

Brazil has one of the highest rates of illicit drug consumption and is considered a major corridor for the trafficking of illicit drugs worldwide. Thus, this article reviews the literature on the consumption, distribution, and main environmental impacts of illicit drugs in Brazil and analyzes the III National Survey on Drug Use by the Brazilian Population. The literature review is based on articles published in national and international journals between 2018 and 2023. This review consists of two analyses, the first of which addresses publications from the last six years on the monitoring of illicit drugs in Brazil and a second analysis based on the III National Survey on Drug Use that addresses the different possibilities of contact with drugs. The results revealed that the Southeast region of Brazil has the highest number of studies on the subject, especially in the state of São Paulo, while the North and Northeast regions have the lowest number of studies. The Midwest regions only have studies in the federal capital city, Brasília, while no studies were found in states bordering countries that produce illicit drugs, such as Paraguay and Bolivia. Analytical methods that use the concept of miniaturization, green chemistry, and the adoption of acceptance methods are frequent in most articles. Chemometric and statistical tools are widely used for the analysis, development, and conclusion of identification and quantification methods. In general, the most used analytical technique is LC-MS/TS, but other techniques have gained ground for the analysis of illicit drugs, such as GC-MS associated with sample preparation and analysis techniques like SPE, TV-LVI, LDI, MALDI, and FTIR, among others. Furthermore, the data show that the consumption of illicit drugs is increasing in Brazil, especially among young people. Thus, there is an urgent need to monitor the levels of illicit drugs in water bodies in different regions of the country to assess epidemiology and environmental contamination and gather indicators for social policies that curb the consumption of these drugs in the Brazilian population.
