Opium farming in Afghanistan has dropped significantly following a ban imposed by the Taliban government in 2022, the United Nations said.

The total area of land for growing opium poppy shrank 20% since last year, while the amount of opium has fallen by 32% over the same period, according to a survey by the UN's Office on Drugs and Crime.

Afghanistan used to produce more than 80% of the world's opium, with heroin made from Afghan opium making up 95% of the market in Europe.

However, after retaking power, the Taliban banned opium cultivation in April 2022, stating that it was harmful and contrary to their religious beliefs. Despite facing severe economic challenges, many farmers adhered to this ban.

Many Afghan farmers are shifting to cereal crops, but the UNODC reported that poppy remains "far more profitable" than legitimate crops. Consequently, over 40% of farmland has remained fallow due to a lack of profitable alternatives and adverse climate conditions.

This year's opium poppy cultivation has been estimated at 10,200 hectares, primarily in the north-east, with Badakhshan province contributing the largest share. Before the 2022 ban, over 200,000 hectares were dedicated to poppy cultivation.

Notably, four provinces declared opium poppy-free in 2025 (Balkh, Farah, Laghman, and Uruzgan), showcasing the effectiveness of the ban.

The Taliban's efforts occasionally met with violent resistance from farmers, particularly in the north-east, where clashes were reported. Nonetheless, most Afghan farmers continue to comply with the ban imposed by the Taliban's supreme leader.

Farmers report challenges in obtaining support for alternative crops, leading them to face a grim choice between poverty and potential punishment for violating the ban. As one farmer from Helmand province expressed, If we violate the ban, we face prison. If we comply, we face destitution. If there's no money, then I'll grow poppies again.

While traditional opium production is in decline, the UNODC noted a surge in trafficking of synthetic drugs like methamphetamine, with seizures increasing by 50% compared to the previous year. Organized crime groups are increasingly opting for synthetic drugs due to their easier production and reduced vulnerability to climate shocks.
