A very interesting read from a long time Indian Foreign Service individual, Ambassador M K Bhadrakumar, regarding current meetings and visits between the Taliban and a number of representatives of various nations, including UK.
During the insurgency years, the Taliban profited from the trade by taxing traffickers, a practice applied on a wide variety of industries in the areas under their control. Research by David Mansfield, an expert on the Afghan drug trade, suggests the group made $20 million in 2020, a small fraction compared to other sources of revenue from tax collection. Publicly, it has always denied links to the drug trade. But the Taliban also implemented the only largely successful ban on opium production, between 2000-2001, before the U.S. invasion. Successive governments have failed to do the same.
