Ethylmethylthiambutene
Ethylmethylthiambutene (N-ethyl-N-methyl-1-methyl-3,3-di-2-thienylallylamine, Emethibutin) is an opioid analgesic drug. It is now under international control under Schedule I of the UN Single Convention On Narcotic Drugs 1961, presumably due to high abuse potential, although little more information is available.
