thanks for the comments. Where in India, all the medical shops having a box to deposit the unused, non-expiry medicines from the public. Later they will handover the medicines to the experts to classify. Once its done, it will be prescribed for the poor or the charity. Actually I wanted to know about like the system in Qatar?

If there is a paramedical team to classify the medics, that can also be donated to the poor countries along with the other donated materials. In Qatar, all the medicine prescribing is really fine grade and quality ones. Our unused medicine can save someones' life somewhere, better do not throw it. This is my concern.
