Welcome to the documentary from the BBC World Service.

This is the fifth floor.

The fifth floor, you knowssonous.

This is the fifth floor at Farnak Amidi Sobath. This is the fifth floor at the heart of global storytelling with BBC journalists from all around the world.

I'm your host, Farak Amidhi.

A few years back, Afghanistan used to produce more than 80% of the world's opium,

the key ingredient for producing heroin.

Opium is extracted from poppy sap,

and places like Helmand Province in the south of the country used to be covered in poppy fields.

These cultivations were so large you could detect them from space.

Over the years, many unsuccessful attempts have been made to clamp down on this illicit trade.

Then the Taliban took over the country, and in 2022, they banned poppy farming completely.

Three years on, how has this measure been implemented and how is it affecting people?

Yama buddies and Mamun Durani from BBC's Afghan service have been looking into this story and they are here

with me in the fifth floor studios. Welcome, gentlemen. Thank you. Great to have you. Nice

meeting you. Thank you. So tell me more about where these poppies are cultivated and who are

the people involved in this trade. We can see a whole family sometimes when they are cultivating a poppy, women are working in the field,

the farmers are working in the field.

Then before 2022, we could say that was across Afghanistan.

You could find it in the northeast.

You could find it in the southern. You could find it in the southern

provinces of Afghanistan, especially Helmand, which was called the capital of opium of Afghanistan.
