Chemical profiles of ecstasy tablets seized in Rio de Janeiro state, Brazil, between 2012 and 2021 reveal MDMA and clobenzorex as the main active ingredients, with less common occurrences of MDA, MDEA, and 2C-B. A total of 27 combinations of cutting agents, including caffeine, ephedrine, and anesthetics, were identified. The occurrence of mega-events in the region altered the chemical fingerprints of the tablets. Samples containing clobenzorex appeared throughout the period in areas near highways, suggesting use primarily by truck drivers. These findings can assist police intelligence in anticipating illicit market changes during major events and identifying trafficking routes.
