 Another candidate for the psychoactive drug is an opioid derived from the poppy.The cult of the goddess Demeter may have brought the poppy from Crete to Eleusis; it is certain that opium was produced in Crete.Another theory is that the psychoactive agent in kykeon is DMT, which occurs in many wild plants of the Mediterranean, including "Phalaris" and/or "Acacia".
