7-PET is an opioid analgesic drug that has 300 times the potency of morphine by weight.[1] It was discovered by K.W. Bentley[2] and is related to the more well known oripavine derivative etorphine, which is used as a veterinary painkiller and anesthetic medication for the sedation of large animals such as elephants, giraffes, and rhinos. 7-PET itself has a 3-O-methyl ether which reduces potency, but the 3-OH derivative is around 2200 times more potent than morphine, almost the same potency as etorphine as a μ agonist,[3][4] and unexpectedly the 3-hydrogen compound is also around the same potency of 2000 times morphine.[5]

Unlike etorphine, 7-PET is not controlled under the UN drug conventions, but it might still be considered to be a controlled substance analogue of etorphine on the grounds of its related chemical structure in some jurisdictions such as the United States, Canada, Australia, and New Zealand.
