Diethyltryptamine
However, despite its structural similarity to DMT, its activity is induced by an oral dose of around 50–100 mg, without the aid of MAO inhibitors, and the effects last for about 2–4 hours.To overcome this, it must be administered in a different manner, i.e. intravenously, intramuscularly, by inhalation, by insufflation, rectally, or by ingestion along with an inhibitor of monoamine oxidase.Because DET has ethyl groups attached to its nitrogen atom, monoamine oxidase is unable to degrade it.[5] Researchers theorized that abnormal metabolites of endogenous chemicals such as tryptamine, serotonin, and tryptophan could be the explanation for mental disorders such as schizophrenia, or psychosis.[8] A Schedule 9 substance is a substance which may be abused or misused, the manufacture, possession, sale or use of which should be prohibited by law except when required for medical or scientific research, or for analytical, teaching or training purposes with approval of Commonwealth and/or State or Territory Health Authorities.
