They should legalize selling everything without a prescription(short of top-tier antibiotics, because people are stupid..) and simply have people show ID and sign a waiver when they buy certain things without a prescription.

As a side-effect.............it would force the pharma industry into becoming a market ruled industry as it would quickly show in sales what worked and what people didn't buy, would likely just as quick show some alternative uses for certain drugs that only people trying would reveal....
