A 20-year-old man with prior hallucinogen experience died after sniffing an unknown amount of dipropyltryptamine, a hallucinogenic tryptamine similar to DMT but with longer duration. Within minutes he had visual hallucinations and apathy; two hours later he developed abdominal pain, collapsed, seized, and vomited. Despite resuscitation and hospital transport, he died 21 hours after consumption. Autopsy showed aspiration of gastric contents and brain edema from oxygen deprivation. Dipropyltryptamine concentrations were 210 ng/ml in antemortem serum, 110 ng/ml in postmortem cardiac blood, and 180 ng/ml in urine. Unlike typical tryptamine overdoses, there was no agitation, hyperthermia, or tachycardia. Death resulted indirectly from a high nasal dose.
