In what way would this cut down on wasted medications? Because it’s portioned? FYI you can still find pharmacies that will pack your medications in blister packs for a nominal surcharge or sometimes free. Or just use a pill box.
So again, find one of the many pharmacies that do blister packing. They don’t all do it tbf but a lot do. A lot of Walmart locations do and many mail order pharmacies will.
Traditional blister packing has been around for years, this isn’t a novel idea. This is just a wasteful implementation
A lot of expensive medication is cheap to manufacture. The money goes to R&D and profits (similar to software). For those medications it's likely that reduced waste would lead to the manufacturer raising the price, keeping the total cost similar.
