Lysergic acid diethylamide (LSD) and phenylethylamine derivatives (NBOHs and NBOMes) are commonly found on seized blotter papers, posing public health risks. Efficient screening methods for identifying these substances are currently limited. To address this, a novel protocol combining colorimetric and electrochemical techniques was developed as a screening method for drugs of abuse in blotter...

In response to the growing need for sustainable analytical methods, this study explores the repurposing of screen-printed electrodes (SPEs) that would otherwise be discarded. This involves recoating the working electrode surface with a graphite (Gr) and chitosan (CTS) dispersion, creating a reusable SPE (SPE-Gr/CTS). Demonstrating its utility, SPE-Gr/CTS was employed for the detection of...

25I-NBOH is a novel psychoactive substance (NPS) recently reported to have been found on blotter paper samples seized on the streets of Brazil, and used as a replacement for the NBOMes now scheduled in many countries. The presence of this NPS on the street market may go undetected, because the most widely and routinely utilised analytical technique for drug sample analyses is gas...

A new potent serotonin 5-HT2A receptor agonist was identified in blotter papers by several state level forensic laboratories in Brazil. The 25I-NBOH is a labile molecule, which fragments into 2C-I when analyzed by routine seized material screening gas chromatography (GC) methods. GC-mass spectrometry (MS), liquid chromatography-quadrupole time-of-flight-MS, and Fourier transform infrared and...
