Investigate missing drugs

I REMEMBER reading in The National during the Public Accounts Committee inquiry into the Health Department’s medicine and pharmaceutical drugs procurement, supply and distribution.
There was a mention of misoprostol (abortion pills or pills that help to induce labour in pregnant women) going missing from area medical stores throughout the country.
Was there ever an investigation into this?
What has been done to monitor and ensure that such drugs are used for their intended purposes, which is to induce labour in pregnant women having difficulties and not sold on the streets for abortion?
Last I checked, abortion is still illegal in Papua New Guinea.
