I was thinking earlier today about the philosophy behind pheromones. According to my dictionary, the definition of a drug is “a substance that has a physiological effect when ingested or otherwise introduced into the body,”
I would think in this case the IS for the “self effects” would be considered a drug since there definitely is a psychological effect going on in this feel good pheromone.
It allmost needs its own classification, because it does have a physiological effect on people but it is a natrual chemical that is produced by the body so it does not have the same risks.
