## What it is

Methamphetamine is a synthetic stimulant of the phenethylamine class, produced in clandestine laboratories rather than grown from cropland. The two primary precursors are ephedrine and pseudoephedrine, chemicals found in cold medicines and sourced mainly from manufacturers in China and India. A growing share of production now uses P-2-P (phenyl-2-propanone), an alternative synthesis route that bypasses ephedrine controls and yields a racemic product with distinct pharmacological effects. The drug circulates as powder, as pressed pills called yaba in Southeast Asia, or as high-purity crystal shards known globally as crystal meth. Because it is lab-based, production is resilient to crop-eradication, weather, and substitution programs that constrain heroin and cocaine supply. The three principal producing blocs are: Mexico's Sinaloa Cartel and Jalisco New Generation Cartel (CJNG), which control the US market; ethnic-armed-organisation militias in Myanmar's Shan State, which dominate Asia-Pacific; and an expanding sector in Afghanistan that emerged as the Taliban's 2022 opium ban displaced narco revenue.

## History

Methamphetamine was first synthesised in Japan in 1919 and was administered to military personnel by multiple powers during World War II. Post-war civilian abuse drove Japan's first major epidemic in the 1950s. In the United States, domestic production peaked at over 23,700 clandestine lab seizures in 2004, concentrated in rural Midwest and western states; the US Combat Methamphetamine Epidemic Act of 2005 restricted retail pseudoephedrine sales, collapsing domestic labs and transferring manufacturing to Mexico. In Asia, Myanmar's Shan State emerged as the dominant global hub through the 1990s under the United Wa State Army, which used drug revenue to finance an autonomous enclave along the Chinese border. Both the Mexican and Golden Triangle supply chains industrialised sharply from roughly 2015, with Shan State labs shifting to industrial-scale output and Mexican cartels expanding distribution networks into Australia and East Asia.

## Current state

As of mid-2026, global production is at or near record levels. The UNODC's World Drug Report 2025 recorded 236 tonnes of methamphetamine seized in East and Southeast Asia in 2024, up 24% year-on-year, with Myanmar's Shan State the dominant production zone. In Afghanistan, UNODC data show seizures in and around the country running roughly 50% above Q3 2023 levels by end-2024, following a near-twelvefold rise from 2017 to 2021, as labs pivot from opium following the Taliban's poppy ban; see [메스암페타민이 아편을 대체하다. 아프가니스탄과 황금 삼각지대가 합성마약으로 전환](/ko/n/synthetic-meth-afghanistan-golden-triangle-2026). In the US market, DEA's 2024 National Drug Threat Assessment confirmed that almost all domestically consumed methamphetamine is manufactured in Mexico by CJNG and the Sinaloa Cartel (see [Mexico's Drug Cartels](/ko/n/mexico-cartels-dossier)), purer and more potent than in prior decades; domestic lab seizures were down to 60 in 2023 from 23,700 in 2004. Methamphetamine and other synthetic stimulants account for roughly 30% of drug-related deaths in the United States, per DEA data.

## Relationships

The trade is structurally tied to armed conflict and the corruption it finances. In Myanmar, UWSA, Shan State Army-South, and Brotherhood Alliance-aligned groups fund military operations through lab taxation and direct production; the civil war has accelerated Shan State output rather than disrupting it (see [중국, 미얀마 반군 동맹을 갈라놓다… 카친은 희토류 지대를 장악](/ko/n/myanmar-brotherhood-alliance-fracture-2026)). In Mexico, meth revenue funds cartel territorial control and the corruption chains spanning precursor importers, wholesale distributors, and law enforcement. Precursor supply is the structural chokepoint: China is the primary source for ephedrine substitutes, and bilateral enforcement agreements between China and the United States, reinforced in 2024, have had limited effect on chemicals routed via third-country transshipment. UNODC's 2026 World Drug Report flagged methamphetamine now crossing the Pacific from North America into Pacific island nations, signalling new trafficking corridors and markets.

## What to watch

- Whether Myanmar's Brotherhood Alliance fracture disrupts or consolidates Shan State lab networks.
- Precursor-control diplomacy between China, the United States, and transit countries following UNODC's 2026 warnings on P-2-P alternative routes.
- Whether Afghanistan's Taliban permits or dismantles meth labs as a fiscal substitute for the banned opium economy.
- Methamphetamine's penetration of Pacific island and Sub-Saharan African markets, flagged in UNODC 2025-2026 reporting.
- US enforcement pressure on Mexican cartels under any renewed cartel-designation framework.
