DESIGNER DRUGS AS A CAUSE OF HOMICIDE

Addiction October 10, 2006 Toshihiko Matsumoto, Takayuki Okada 29 citations

A 22-year-old man with no prior mental illness committed a homicide during a severe psychotic state induced by the designer drugs 5-MeO-DIPT and 5-MeO-MIPT, which he purchased online. He ingested unknown quantities of 'Wild Game' and 'Mipty' to enhance sexual pleasure, but within 1.5 hours experienced palpitations, nausea, delusions, visual distortions, and loss of consciousness. Police found him naked and confused 3 hours later; his girlfriend had been killed with a kitchen knife. Laboratory tests confirmed the tryptamine derivatives in his urine and her body; no other substances were detected. Clinical recovery occurred after 17 hours, with amnesia for the event. This is the first reported homicide linked to these drugs, and the authors suggest that simultaneous intake of both analogues may prolong serotoninergic overactivation, causing severe psychosis.
