Clinical symptoms and blood concentration of new psychoactive substances (NPS) in intoxicated and hospitalized patients in the Budapest region of Hungary (2018-19)

Abstract

The ratio of SCs among the selected intoxicated patients was higher than expected from seizure data which could be the consequence of targeted patient selection. The clinical symptoms and the severity of intoxication cannot be characterized simply by NPS blood levels. The short half-life of SCs can explain the relatively rapid consolidation of intoxication symptoms.HighlightsIn the Budapest region, the majority of hospitalized NPS intoxications was caused by the synthetic cannabinoids 5F-MDMB-PINACA and 5F-MDMB-PICA in 2018-19.No correlation between blood concentration and symptoms severity could be established.The clinical symptoms of synthetic cannabinoid users improved quickly and no ICU treatment was necessary.The half-life of 5F-MDMB-PINACA and 5F-MDMB-PICA was proved to be 2.50 hours and 2.68 hours, respectively.
