Asia Meth Seizures Surge as Myanmar Becomes a Major Production Hub
Methamphetamine seizures across East and Southeast Asia reached a record 349 metric tons in 2025, surging 48% from the previous year as production centers in Myanmar accelerated manufacturing. The 2025 total stands at more than five times the figure recorded a decade earlier, with the two regions accounting for nearly half of all global seizures by weight as of 2024.
Drug cartels inside the Golden Triangle—which straddles the borders of Myanmar, Thailand, and Laos—have increasingly shifted from traditional opium and heroin production to mass-produced synthetic drugs since the 1990s. That trade expansion intensified following the 2021 military takeover in Myanmar. Political instability and subsequent armed conflict have hampered law enforcement efforts. Since October 2023, ethnic armed groups expanding their territorial control have used methamphetamine profits to purchase weapons.
Plunging Prices and Regional Spikes
The surge in regional production has flooded local markets with remarkably cheap product. Methamphetamine tablets now sell for 30 baht, or about 89 cents, per pill in Thailand, dropping to roughly one-fifth of their price from a decade ago, according to Sayamol Charoenratana, a researcher at Chulalongkorn University. Online accessibility has further simplified purchases.
Law enforcement data reveals soaring interception rates across neighboring nations. Thailand recorded a 23% increase in meth seizures in 2025. Over the same period, seizures nearly quadrupled in Malaysia, almost tripled in the Philippines, and rose by roughly 80% in Indonesia. Meanwhile, an online fraud operation was discovered near a methamphetamine production facility during a major law enforcement raid in Myanmar’s Shan state in January, highlighting links between drug manufacturing and organized scam networks across Southeast Asia.
Criminal Networks Smuggle Precursor Chemicals from China and India
The production network relies on a steady influx of precursor chemicals originating largely from China and India. China plays a central role in supplying these materials to Myanmar, with smuggling routes frequently passing through Ruili in western Yunnan province. Although Beijing has tightened export controls on specific precursor chemicals, criminal organizations bypass restrictions by substituting dual-use substances that possess legitimate industrial applications.
Trafficking networks have simultaneously expanded long-range smuggling operations aimed at wealthy nations where high-purity crystal methamphetamine commands steep prices. In July, authorities at Fukuoka Airport in southwestern Japan intercepted approximately 900 grams of crystalline methamphetamine hidden in the luggage of a Thai woman. Japan’s Ministry of Finance reported 73 stimulant smuggling cases involving air passengers in 2025, marking a 22% increase from the prior year, while total seized quantities jumped 93% to 664 kilograms. High-purity crystal meth remains the dominant form of the drug in Japan and South Korea, according to Chiang Mai University lecturer Apinun Aramrattana.
To address the cross-border trafficking networks, Myanmar President Min Aung Hlaing and Thai Prime Minister Anutin Charnvirakul issued a joint statement in early August reaffirming their commitment to strengthening cooperation on the prevention and suppression of narcotic drugs and related precursor chemicals.
