New psychoactive tryptamines may be a public health risk since they intend to mimic the hallucinogenic effects of regulated psychoactive drugs. Few studies describe uses and clinical effects of unregulated new psychoactive tryptamines. This study aims (1) to explore the presence of tryptamines classified as NPS among the substances delivered for analysis to a harm-reduction organization; (2) to describe the substances found in the samples after analysis; and (3) to compare analytical results of regulated vs. non-regulated tryptamines. Samples delivered and analyzed by gas chromatography-mass spectrometry from 2006 to 2015 were included. A descriptive study of results was conducted. From 25,296 samples that were delivered, 436 were tryptamines; from these 232 (53.21%) were non-regulated. The most delivered non-regulated tryptamine was 4-AcO-DMT. A search of the PubMed database in July 2016 revealed that no studies in humans have ever been carried out with 4-AcO-DMT. Unregulated tryptamines likely contained one unadulterated substance (p ≤ 0.001). The number of samples submitted which contained tryptamines increased during the course of the study, with significant differences in client expectations vs. analysis results between the controlled and uncontrolled groups. There is a need for further research in order to prevent the potential health risks associated with their use.
IntroductionNew Psychoactive Substances (NPS) appear to be increasing in popularity because they mimic the effect of traditional drugs. DOB is a world-wide controlled phenethylamine, with agonist activity in 5HT2A receptors. Its effects are comparable to those of LSD, with dosage range 1.0–3.0 mg and duration 18–30 h.ObjectiveTo assess the presence of DOB in the substances submitted to, and analyzed by, energy control.Materials and methodsAll samples presented to Energy Control (EC) from August 2009 to August 2015 were analyzed. EC is a spanish harm-reduction non governmental organization that offers to users the possibility of analyzing the substances they intend to consume. Samples in which DOB was detected using gas chromatography-mass spectrometry were selected for this study.ResultsFrom a total of 20,062 samples, 13 contained DOB (0,06%), with no clear variations among the years studied. The samples were mostly sold as DOC(8), DOB(2) and LSD(2). Nine out of total 13 samples presented as blotter.ConclusionResults suggest that availability of DOB in the Spanish drug market is anecdotic. Nonetheless, a number of the samples containing DOB were not sold as such, increasing the possibility of side effects, as users may ignore which substance they are actually using. When a patient presents at an Emergency Department with persistent hallucinogenic symptomatology after ingesting a blotter, psychiatrist should be aware of long-lasting psychedelics such as DOB.Disclosure of interestThe authors have not supplied their declaration of competing interest.
