"Myanmar has made south-east Asia’s largest-ever seizure of synthetic drugs in raids that revealed “unprecedented” production of opioids in the area, the UN has said. Between February and April, authorities swooped on labs in the lawless Kutkai area of Shan state, seizing nearly 200m meth tablets, 500kg (1,100lbs) of crystal meth, 300kg of heroin, and 3,750 litres of methyl fentanyl.

The production network could have been possible only with the backing of serious transnational criminal groups, he added. The raids unearthed “unprecedented” methyl fentanyl, the sign of a new trend of synthetic opioid production emerging “on a scale nobody anticipated”, said Douglas. Fifty times stronger than heroin and up to 100 times more potent than morphine, fentanyl can be lethal from as little as two milligrams – the equivalent of a few grains of sand. It has fuelled an opioid crisis in the US that killed 32,000 people in 2018. Myanmar is under pressure to stem the deluge of drugs from its border regions.
