Myanmar is now the world's largest producer of opium, overtaking Afghanistan. That’s after the Taliban banned the cultivation of opium poppies, which can be used to make heroin.

Yogita Limaye, the BBC’s South Asia and Afghanistan correspondent, explains how the ban has impacted farmers who previously depended on opium to survive. And Soe Win Than, editor of the BBC Burmese Service, tells us how corruption and political instability in Myanmar have contributed to the growth in opium production.
