Brazilian Case

The new psychoactive substances (NPS) market is in a constant state of flux, with new substances being synthesized regularly and marketed in many ways and forms. These substances often emerge quickly, just as they disappear, evidencing a clear attempt to circumvent the control trafficking enforcement agencies and the international community. Among the wide variety of NPS, the NBOMe series attracted attention from medical and legal authorities due to the high number of cases of intoxication, followed or not by death in several countries around the world, including Brazil. So, this brief communication aimed to evaluate the number of NBOMe Brazilian Federal Police (BFP) over the past eight years, and highlight the NPS constant state of flux, evidencing by the Brazilian NBOMe case. This is a retrospective study based on information from forensic analysis reports from seizures of BFP. The NBOMe seizures generated 4 forensic analysis requests in 2012, 21 in 2013, 45 in 2014, 61 in 2015, 80 in 2016, 22 in 2017, 19 in 2018 and 2 in 2019, totaling 254 forensic analysis reports analyzed. This NPS emerged quickly in Brazil from the year 2012, and tented to disappear in recent years, from the perspective of the BPF forensic analysis reports, evidencing the NPS constant state of flux, represented here by the Brazilian NBOMe case.

The use of the new psychoactive substances is continuously growing and the implementation of accurate and sensible analysis in biological matrices of users is relevant and fundamental for clinical and forensic purposes. Two different analytical technologies, high-sensitivity gas chromatography-mass spectrometry (GC-MS) and ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) were used for a screening analysis of classic drugs and new psychoactive substances and their metabolites in urine of formed heroin addicts under methadone maintenance therapy. Sample preparation involved a liquid-liquid extraction. The UHPLC-HRMS method included Accucore™ phenyl Hexyl (100 × 2.1 mm, 2.6 μm, Thermo, USA) column with a gradient mobile phase consisting of mobile phase A (ammonium formate 2 mM in water, 0.1% formic acid) and mobile phase B (ammonium formate 2 mM in methanol/acetonitrile 50:50 (v/v), 0.1% formic acid) and a full-scan data-dependent MS2 (ddMS2) mode for substances identification (mass range 100–1000 m/z). The GC-MS method employed an ultra-Inert Intuvo GC column (HP-5MS UI, 30 m, 250 µm i.d, film thickness 0.25 µm; Agilent Technologies, Santa Clara, CA, USA) and electron-impact (EI) mass spectra were recorded in total ion monitoring mode (scan range 40–550 m/z). Urine samples from 296 patients with a history of opioid use disorder were examined. Around 80 different psychoactive substances and/or metabolites were identified, being methadone and metabolites the most prevalent ones. The possibility to screen for a huge number of psychotropic substances can be useful in suspected drug related fatalities or acute intoxication/exposure occurring in emergency departments and drug addiction services.
