Something New about Something Old: A 10-Year Follow-Up on Classical and New Psychoactive Tryptamines and Results of Analysis

Journal of Psychoactive Drugs June 1, 2017 Álvaro José Palma-Conesa, Mireia Ventura, Liliana Galindo et al. 65 citations

New psychoactive tryptamines, which mimic the effects of regulated hallucinogens, pose a potential public health risk. Analysis of 25,296 samples submitted to a harm-reduction organization from 2006 to 2015 identified 436 tryptamines, of which 232 (53.21%) were not regulated. The most common unregulated tryptamine was 4-AcO-DMT, for which no human studies exist. Unregulated tryptamines were more likely to contain a single unadulterated substance. The number of tryptamine samples increased over time, and there were significant differences between client expectations and actual analysis results for regulated versus unregulated groups. Further research is needed to address health risks.

Acute Effects of 2C-E in Humans: An Observational Study

Frontiers in Pharmacology March 18, 2020 Esther Papaseit, Marta Torrens, Mireia Ventura et al. 20 citations

2C-E, a psychedelic phenylethylamine similar to mescaline, acts as a partial agonist at serotonin 2A, 2B, and 2C receptors and inhibits norepinephrine and serotonin uptake. In an observational study, ten recreational psychedelic users self-administered single oral doses of 2C-E (6.5–25 mg). The drug induced alterations in perception, hallucinations, and euphoric mood, with saliva concentrations peaking 2 hours after administration. The effects resembled those of 2C-B and other serotonin-acting drugs.

What are sweet dreams made of? Analysis of psychoactive substances into “gummies”: A retrospective descriptive study

European Psychiatry April 1, 2017 Amira Trabsa, E. Monteagudo, D.d. Mariona et al. 2 citations

Among 8324 drug samples submitted to a Spanish harm-reduction organization between 2014 and 2015, nine were gummy formulations—a novel delivery form for psychoactive substances. Analysis by gas chromatography-mass spectrometry showed that 55.5% of these gummies contained multiple drugs. The most common substance was 25N-NBOMe, found in 66.7% of samples; other detected substances included 2C-E, 2C-D, allylescaline, cocaine, THC, ketamine, MDMA, and caffeine. Only 25N-NBOMe was present in an active dosage. Two-thirds of the gummies did not contain the substance the consumer expected, indicating risks of unintended effects.
