The topic of this paper relates to the study of cases involving the use of new psychoactive substances (NPS) from the classes of synthetic cannabinoids and cathinones, analyzed from multiple viewpoints including clinical and medico-legal perspectives. The paper investigates three fatal cases in which UR-144 and UR-144 with pentedrone identified in the bodies of victims during post-mortem examinations were responsible for the tragic consequences and proved to be the indirect cause of death. The victims were men aged 16, 22 and 40 years who used drugs, for example they smoked marijuana or its substitutes in the form of synthetic cannabinoids. In addition, all of them had behavioural problems. On account of emotional imbalance attributable probably to the presence of UR-144 (in one case) and a mixture of UR-144 and pentedrone (in the other two cases), two men committed suicide by jumping from a height and hanging, and one man had fatal accidental poisoning with pentedrone which was used to enhance the effect of previously used UR-144.

The presence of UR-144 and pentedrone in the post-mortem material was analyzed by liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS-MS).

The results of toxicological tests were analyzed with a focus on possible tragic side effects caused by the presence of UR-144 and UR-144 with pentedrone in the body.
