OG, that's kind of true....about only being prescribed what you need. It will happen that people are prescribed items that are taken when needed, or the prescription is changed or for other reasons, and then the person ends up with a "stash" of meds which they don't use and which can't be re used. I used to visit older people at home and often found medication stashes. The fact that I found them means that they weren't fraudulently asking for them and then selling them, but its still a significant amount of waste.
