Lethal trade in fake medicines.

Large amounts of counterfeit drugs are being sold to countries in the developing world, offering treatments like a fake life-saving medicine for children, but leaving these countries unprotected against deadly diseases such as malaria. Why are the World Health Organisation and the major drugs companies not effectively stamping out this trade? Allan Urry investigates. He visits Ghana to see how such fake medicines circulate from the towns to the villages and hears dreadful stories of the effects of some of these medicines, including the story of how poisoned glycerine usad as pain relief medicine in Haiti, killed more than 80 children.
