Combining FTIR-ATR and OPLS-DA methods for magic mushrooms discrimination

Forensic Chemistry April 8, 2022 Cátia Esteves, Elena M. M. de Redrojo, José Luis Manjón et al. 19 citations

Magic mushrooms are naturally occurring fungi that are considered hallucinogenic drugs because they contain psilocybin and psilocin. These substances are controlled in almost every country in the world, so the use, possession, cultivation, and sale of magic mushrooms are prohibited in whole or in part. Despite this, the abuse of magic mushrooms continues and can put at risk the life of the...

Potential of High-Resolution Mass Spectrometry for the Detection of Drugs and Metabolites in Hair: Methoxetamine in a Real Forensic Case.

Journal of Analytical Toxicology February 14, 2022 J M Matey, Adrián López-fernández, Carmen García-ruiz et al. 13 citations

The analysis of drugs of abuse in hair and other biological matrices of forensic interest requires great selectivity and sensitivity. This is done traditionally through target analysis, with one or more analytical methods, or with different and specific preanalytical phases, and complex procedures performed by the toxicological laboratories, and there is no exception with ketamine-like...

Prevalence study of drugs and new psychoactive substances in hair of ketamine consumers using a methanolic direct extraction prior to high-resolution mass spectrometry.

Forensic Science International December 1, 2021 J M Matey, Gemma Montalvo, Carmen García-ruiz et al. 19 citations

Few studies have reported the prevalence or incidence about the consumption of new psychoactive substances (NPS). The hair analysis can be useful for this purpose. At the present, ketamine is the most consumed arylcyclohexylamine associated to young consumers and polyconsumption profiles. For this reason, ketamine consumer cases become very interesting to provide information on NPS prevalence....

Identification of 2C-B in Hair by UHPLC-HRMS/MS. A Real Forensic Case.

Toxics July 15, 2021 José Manuel Matey, Adrián López-fernández, Carmen García-ruiz et al. 7 citations

The analysis of drugs of abuse in hair and other biological matrices of forensic interest requires great selectivity and sensitivity. This has been traditionally achieved through target analysis, using one or more analytical methods that include different preanalytical stages, and more complex procedures followed by toxicological laboratories. There is no exception with 2C-series drugs, such as...
