Seized Blotters Containing One Regioisomer of 25I-NBOMe

The NBOMe class, mostly represented by the 25I-, 25B- and 25C-NBOMe compounds, is one example among many potentially lethal new psychoactive substances (NPSs) which have emerged in the illegal drugs markets around the world during the last years. Blotters impregnated with NBOMes instead of traditional lysergic acid diethylamide (LSD) have been seized for the first time in mainland China. After proposing the pathway of EI-induced fragmentation of 25-I-NBOMe, we also distinguish the possible regioisomers with similar MS results a by the comparison of the fragment ion abundances and the retention time.
