Tens of millions of dollars worth of medication is winding up in landfill every year, due to it being illegal to do anything other than throw it away.

Medication is frequently returned due to things such as changes in a person's prescription, no longer requiring a treatment, or even the end of a person's life.

Pharmacist Puneet Saini told Mike Hosking that a number of these returned medications are untouched, unused, and unexpired.

He said that there's precedent from overseas, with companies in the United States and Greece reallocating unused medication.
