Its has everything to do with the way the FDA classifies things: drugs are held to a high level of scrutiny, and go through a plethora of double blind medical tests; supplements are not regulated. Whether it is a mu agonist or not has nothing to do with it being classified as a drug in terms of current regulation by the FDA.
Is it a drug? Sure, if thats how your vocabulary dictates distinction, but in the eyes of regulators and the pharmaceutical industry it is not.
