Pyrrolidinylthiambutene is an opioidanalgesic drug from the thiambutene family with around 3/4 of the potency of morphine.[1][2][3] It would be considered an illegal controlled substance analogue in some countries such as the USA, Australia and New Zealand, but is legal in countries not possessing a controlled-substances-analog-act equivalent.
