Afghanistan used to produce more than 80% of the world's opium, the key ingredient for the drug heroin. When the Taliban took over, they banned poppy farming completely. 3 years on, how has this measure been implemented and how is it affecting people? Yama Bariz and Mamoon Durrani from the BBC's Afghan service discuss the effectiveness of the Taliban's poppy eradication campaign and explain how the trade is moving to Pakistan.

This episode of The Documentary comes to you from The Fifth Floor, the show at the heart of global storytelling, with BBC journalists from all around the world.
