Chemical and statistical analyses of blotter paper matrix drugs seized in the State of Rio de Janeiro

Does Conformation Affect the Analytical Response? A Structural and Infrared Spectral Evaluation of Phenethylamines (2C-H, 25H-NBOH, and 25I-NBOMe) Using In Silico Methodology

“…According to the United Nations Office for Drugs and Crime (UNODC), NPSs are substances of abuse that are not controlled by the 1961 Single Convention on Narcotic Drugs or the 1971 Convention on Psychotropic Substances. The term "new" implies that such substances have recently appeared on the market despite being synthesized and known years before [1][2][3][4]. Therefore, the rapidity with which such substances are gaining popularity threatens public health and safety.…”

A simple, quick and non-destructive approach for sampling drugs of abuse in tablets and blotter for qualitative analysis by paper spray mass spectrometry

“…3 In other Brazilian states, such as Rio de Janeiro and Santa Catarina, a considerable growth in NPS in the composition of drugs conveyed in blotter paper has also been observed. 4,5 Current Brazilian legislations determine the chemical iden-tication of the seized substances, through expert examination a Departamento de Química, Instituto de Ciências Exatas, Universidade Federal de Minas Gerais, Antônio Carlos Ave., 6627, CEP 31270-901, Belo Horizonte, MG, Brazil b Seção Técnica de Física e Química Legal, Divisão de Laboratórios, Instituto de Criminalística, Superintendência de Polícia Técnico-Cientíca, Polícia Civil de Minas Gerais, Augusto de Lima Ave., 1833, CEP 30110-017, Belo Horizonte, MG, Brazil.

Comprehensive detection of lysergic acid diethylamide (LSD) in forensic samples using carbon nanotube screen-printed electrodes

“…The determination of LSD in blotter papers has been extensively reported using various analytical methods, such as LC-MS-MS, 2,5,6 LC-MS, 1,7 and GC-MS. 8,9 Though these methods offer high sensitivity and selectivity for LSD detection, they require a large-size laboratory, specialized personnel, and involve time-consuming processes and sample pretreatments for forensic analysis. 10 Additionally, while LC-MS and GC-MS serve as definitive identification methods for drugs in forensic samples, screening tests for preliminary identification are also essential.…”
