Ethylmethylthiambutene (N-ethyl-N-methyl-1-methyl-3,3-di-2-thienylallylamine; Emethibutin) is an opioid analgesic drug from the thiambutene family, around 1.3x the potency of morphine.[2][3][4] It is under international control under Schedule I of the UN Single Convention On Narcotic Drugs 1961, presumably due to high abuse potential.
