Heroin and morphine seizures remain concentrated in Asia.

• In line with the concentration of opium production in Asia, almost two thirds (64 per cent) of global heroin and morphine seizures occurred in Asia in 2024, notably in South-Western Asia and, to a lesser extent, in East and South-East Asia.
• In 2024, the Islamic Republic of Iran – bordering Afghanistan – reported the largest seizures of opium, morphine and heroin. The next largest heroin seizures were reported by Pakistan, Egypt and Türkiye, largely linked to (possibly stockpiled) opiates produced in Afghanistan.
• Heroin and morphine seizures declined strongly in the Near and Middle East, South-West Asia and Europe in line with substantially reduced Afghan opium production, while increasing in East and South-East Asia.
