Watch part two 

Afghanistan produces more than 90 per cent of the world's opium.
It is a multi-billion dollar industry that, according to the US military, funnels an estimated $100-$500m to the Taliban each year.

The main production centre of Afghan opium is the southern Helmand province, a known stronghold for the Taliban.

In fighting a military war, has the US overlooked a vast drug trade that is still funding an insurgency?

Joining the show is journalist and author Gretchen Peters.

She covered Pakistan and Afghanistan for more than a decade and spent five years travelling the border areas between the two countries to research and write her new book Seeds of Terror: How Heroin is Bankrolling the Taliban and al Qaeda.
