Abstract

IntroductionNew designer benzodiazepines such as phenazepam, etizolam, diclazepam, clonazolam and flubromazolam have appeared in the recreational drug market due to that they provide an attractive alternative to prescription-only benzodiazepines as they are readily available over the Internet.ObjectiveTo describe the presence of new designer benzodiazepines in samples delivered to energy control since 2010 to 2016 in Barcelona.MethodsFrom 2010 to 2016, 24,551 samples were delivered to energy control. Among this samples 43 (0.175%) were analysed as benzodiazepines. They were analyzed by energy control, a Spanish harm reduction NGO that offers the possibility of analyzing the substances that users report. Analysis was done by gas chromatography-mass spectrometry.ResultsFrom the 43 samples analyzed as benzodiazepines, 1 (2.32%) was delivered in 2010, none in 2011, 2 (4.65%) in 2012, 2 (4.65%) in 2013, 1 (2.32%) in 2014, 15 (34.88%) in 2015 and 21 (48.83%) in 2016.DiscussionThe data shows that new designer benzodiazepines use is increasing in Barcelona, especially in the last two years. Abuse an addiction to these drugs may be a new public health problem in Barcelona.

Abstract

Introduction New psychoactive substances (NPS) are substances that have recently appeared on the market and are not under international control. NPS use is experiencing an unprecedented increase. DiPT, 4-HO-DiPT and 4-AcO-DiPT are new psychoactive tryptamines and their effects may differ from those of other psychoactive tryptamines. Objective To explore the presence of DiPT, 4-HO-DiPT and 4-AcO-DiPT from samples delivered to and analyzed by Spanish harm reduction service Energy Control. Materials and methods All samples analyzed from 2009 to 2014 delivered as DiPT, 4-HO-DiPT and 4-AcO-DPT or containing these substances. Analysis was performed by gas chromatography–mass spectrometry. Results From 17,432 samples, 4-HO-DiPT was found in 16, delivered as 4-HO-DiPT (6); 4-AcO-DiPT (7); DiPT (1); 4-AcO-DMT (1) and cocaine (1). 4-AcO-DiPT was found in 16, delivered as 4-AcO-DiPT (12); 5-MeO-DMT (1); 5-MeO-DiPT (1); 4-AcO-DMT (1) and cocaine (1). Only 4 samples contained DiPT, all presented as DiPT. Nine samples contained both 4-AcO-DiPT and 4-HO-DiPT. During the years of study, 4-HO-DiPT deliverance was increasing (4 samples in 2014) while deliverance of 4-AcO-DiPT and DiPT was decreasing (1 sample in 2014). Conclusions Increasing 4-HO-DiPT presence could translate a progressive replacement of 4-AcO-DiPT and DiPT recreational use. Clinical relevance comes from its growing use and the absence of scientific evidence on humans, therefore relying on users subjective experience to predict the effects. [ABSTRACT FROM AUTHOR]
