Loss of Consciousness and Visual Hallucinations Related to 5-MeO-DALT Intake, a Case Report Confirmed by Toxicological Analyses.

A 46-year-old man experienced a brief loss of consciousness and visual hallucinations after taking three tablets of the hallucinogenic tryptamine derivative 5-MeO-DALT, purchased online. Laboratory analysis quantified 32.5 mg of the drug per tablet (11% purity) and 7 ng/mL in the patient's plasma 8 hours after consumption. Poisonings from 5-MeO-DALT are rarely reported, but the broad availability of such products means emergency physicians and clinical toxicologists should consider recreational tryptamine ingestion, especially because most routine toxicological screenings do not detect them.

Abstract

5-MeO-DALT or 5-methoxy-N,N-diallyltryptamine is a derivative of tryptamines, consumed for its hallucinogenic and entheogenic effects. We report the case of a 46-year-old-man, presenting with a brief loss of consciousness and visual hallucinations, after the consumption of three 5-MeO-DALT tablets bought online. Liquid chromatography coupled to tandem mass spectrometry method was performed, and 5-MeO-DALT was quantified in both the tablets (32.5 mg per tablet, 11% of purity) and the patient's plasma (7 ng/mL-8 h between the consumption and the blood sample). 5-MeO-DALT poisonings are rarely described. Given the broad availability of these products, it is important that emergency department physicians and clinical toxicologists do not overlook the possibility of the ingestion of recreational tryptamines, especially since they are not detected by most routine toxicological screening.
