South East Asia's Golden Triangle used to be notoriously known as the world's largest opium producing region. For some time now authorities have been trying to halt the cultivation and trade of this deadly narcotic. The Thai royal family went as far as taking the initiative to start a program to provide technical support and financial incentives to encourage farmers to switch from opium to coffee growing. But although such bold steps are admirable, the trafficking of illicit substances continues. This episode of Asia Insight focuses on the ongoing battle against drugs and the changes taking place across the region.
