Blotters sold as LSD in two Colombian cities actually contain mixtures of new psychoactive substances (NPS), including DOB, 25I-NBOMe, MDMA, and 25I-NBOMe imine, all phenylethylamines. Analysis of 70 doses from forensic cases in Bogotá and Barranquilla, using gas chromatography–mass spectrometry, revealed these adulterants. The findings indicate a growing public health problem, as these blotters cause intoxication and death, especially when mixed with other drugs.
