Summary
AI-generated from the abstractBetween 2009 and 2015, 56 samples of the potent hallucinogen 25I-NBOMe were identified among 21,198 drug samples submitted to a Spanish harm-reduction service. Most samples (42.8%) were sold as LSD, while only 21.4% were sold as 25I-NBOMe itself; others were misrepresented as related substances or even gummy bears. All 25I-NBOMe samples appeared after 2012, with a peak in 2013. The substance has high affinity for serotonin 5HT2a receptors and has been linked to toxicity. The authors call for more research and for physicians to be aware of novel psychoactive substances and their clinical differences.

Abstract
IntroductionNovel psychoactive substances (NPS) use is progressively increasing year on year. A new group of phenethylamines sold as legal stimulants and hallucinogens is being reported increasingly since 2012. Within this group, 25I-NBOMe is an outstanding substance with powerful effects and high affinity with the serotonin 2a (5HT2a) receptor. Several toxicity cases have been reported so far.ObjectivesTo describe the presence of 25I-NBOMe and its characteristics in samples delivered to Energy Control from 2009 to 2015 in Spain.MethodsAmong the samples, 21,198 analyzed from august 2009 to august 2015 and only those samples containing 25I-NBOMe were studied (n = 56). Samples were analyzed by Energy Control, a Spanish harm-reduction NGO that offers users the possibility of analyzing the substances they intend to consume. Analysis was done by Gas Chromatography–Mass Spectrometry.ResultsFrom 56 samples were 25I-NBOMe was found, 24 were bought as LSD (42.8%), 12 as 25I-NBOMe (21.4%), 4 as 25C-NBOMe (7.1%), 4 as 25I-NBOH (7.1%) and 12 as other substances (21.4%), gummy bears included. All samples were received from 2012 on, having the highest peak on 2013 (19 samples).Conclusions25I-NBOMe consumption represents an emerging issue with potential harmful effects, especially when the substance used is not the expected. Further pharmacokinetic, pharmacodynamic, clinical and epidemiological researches should be conducted to deepen knowledge about 25I-NBOMe and the management of its possible toxic effects. Physicians should be aware of NPS, their increasing use and the clinical differences between them.Disclosure of interestThe authors have not supplied their declaration of competing interest.
