Startup Idea : Used Medicines Dropbox for Poor

There are several instances experienced by each of us. We buy a medicine as per the prescriptions, and might stop in between either as per doctor's instructions or Voluntarily. That broken strip is not even purchased back by the Chemist shops. We can create a dropbox at every chemist shop and people voluntarily donate their used straps. It will then be filtered by the Chemist owners for their expires and can be then donated to poor and needy for free. We need intervention of chemist to filter expiries and issue medicines to poor only against a valid Doctor's prescription. This is a non-profit motive so no revenues expected.
