Piperidylthiambutene (Piperidinohton) is an opioid analgesic drug from the thiambutene family, which has around the same potency as morphine.[1][2][3] If sold or obtained for the purpose of human consumption it could be considered a controlled substance analogue in some countries such as the US, Australia and New Zealand. Piperidylthiambutene has been sold as a designer drug, first appearing in late 2018.[4]
