The production of opium in Myanmar has flourished since the military's seizure of power, with the cultivation of poppies up by a third in the past year as eradication efforts have dropped off and the faltering economy has led more people toward the drug trade, according to a United Nations report released Thursday.

In 2022, in the first full growing season since the military wrested control of the country from the democratically elected government of Aung San Suu Kyi in 2021, Myanmar saw a 33% increase in cultivation area to 40,100 hectares (99,090 acres), according to the report by the U.N. Office on Drugs and Crime.

The overall value of the Myanmar opiate economy, based on U.N. estimates, ranges between $660 million and $2 billion, depending on how much was sold locally, and how much of the raw opium was processed into heroin or other drugs.

"Virtually all the heroin reported in East and Southeast Asia and Australia originates in Myanmar, and the country remains the second-largest opium and heroin producer in the world after Afghanistan," Douglas said. "There is no comparing the two at this point as Afghanistan still produces far more, but the expansion underway in Myanmar should not be dismissed and needs attention as it will likely continue — it is directly tied to the security and economic situation we see unfolding today.”

The so-called Golden Triangle area, where the borders of Myanmar, Laos and Thailand meet, has historically been a major production area for opium and hosted many of the labs that converted it to heroin. Decades of political instability have made the frontier regions of Myanmar, also known as Burma, largely lawless, to be exploited by drug producers and traffickers.

Most of the opium exported by Myanmar goes to China and Vietnam, while heroin goes to many countries across the region, Douglas said.

“It is really where the value is for traffickers,” he said. “Very high profits.”

Production estimates hit a bottom of 400 metric tons (440 tons) in 2020. After rising slightly in 2021, that spiked in 2022 to an estimated 790 metric tons (870 tons), according to the report.

Since it took control of the government, the military's use of deadly force to hold on to power has escalated conflict with its civilian opponents to the point that some experts describe the country as now being in a state of civil war.

The costs have been high, with 2,810 people killed by government forces to date and 17,427 detained, according to the Assistance Association for Political Prisoners.

The violence has meant that the government has been unable to reach some areas to carry out drug eradication raids, and has also had to divert its resources elsewhere. Consequently, eradication efforts appear to have decreased substantially, with 1,403 hectares (3,467 acres) reported eradicated in 2022 — some 70% fewer than in 2021.

At the same time, as the conflict continues to take its toll on Myanmar's economy, an increasing number of rural households have been pushed into relying more on opium cultivation for income, the U.N. said.

“The expansion of opium production that is underway is fundamentally about poverty and people in rural areas reacting to the economic situation,” Douglas said. “It has always been there in tough times. At the same time, the security situation is clearly difficult with increasing frequency and intensity of conflict, and those involved in the drug economy have been left largely unchecked.”

Its synthetic drug economy has also been surging for the same reasons, with reported regional seizures of methamphetamine and other drugs reaching record levels. In a single bust in September in Laos, for example, authorities seized 33 million methamphetamine tablets along with 500 kilograms (1,100 pounds) of crystal methamphetamine.
