Afghanistan's opium production is booming despite the Western world's repeated attempts to stop production.
It provides food for many Afghan farmers and accounts for a large part of the country's sources of income.
But 20 years ago, production stopped almost completely.
During his last term in power, the Taliban banned poppy cultivation for opium production and the Afghans obeyed.
Now the Taliban say a new ban is underway, but in order to keep it, they need assistance from the outside world.
"There will be less opium in the world," said Khairullah Shinwari, an activist and Taliban supporter.
Need other crops
He says opium has flowed out of Afghanistan in recent years because members of the former US-backed government were themselves involved in the opium trade.
- So there was no commitment because you had your own interest and made money from this.
They received international support and assistance, everything, but they could not ban the crops because they had a vested interest.
The Taliban are committed, but need international help.
Aid is a prerequisite
The aid, which many countries have withdrawn after the Taliban took power, he says is a prerequisite for getting rid of opium cultivation.
- The Taliban can ban the cultivation, but to put an end to it, an alternative is needed for the farmers so that they can cultivate something else and support themselves.
