India’s Eastern Borders Affected by Flow of Opium from Myanmar
SUBJECT: INTERNAL SECURITY
Context
According to the Narcotics Control Bureau (NCB) Annual Report 2026, Myanmar has replaced Afghanistan as the world’s leading source of illicit opium following the Taliban’s 2022 ban on poppy cultivation. This has significantly increased narcotics trafficking into India’s northeastern States.
Key Highlights
Myanmar Route (Eastern Border)
- India’s Manipur, Mizoram and Nagaland have become the frontline States affected by narcotics flowing from Myanmar.
- Porous borders and the Free Movement Regime (FMR) have facilitated cross-border drug trafficking.
- These States have evolved from transit corridors into staging and distribution hubs for narcotics entering mainland India.
Why Myanmar Matters
- Illicit opium cultivation in Myanmar increased by 56% (2021–2023), reaching 45,200 hectares.
- Production is concentrated in Shan State, particularly in areas controlled by ethnic armed groups.
- Myanmar’s Golden Triangle is a major global centre for:
- Illicit opium cultivation
- Heroin production
- Methamphetamine (Yaba) manufacturing
Major Trafficking Routes
- Manipur Corridor: Primary land route for heroin and methamphetamine entering India through National Highway-102.
- Mizoram Corridor: Drugs enter through Champhai district, move via Aizawl–Silchar, and spread into mainland India.
Major Drug Seizures (2025)
- Mizoram: 1,477 kg ATS (highest in India)
- Manipur: 535 kg
- Delhi: 454 kg
- Gujarat: 308 kg
- Karnataka: 164 kg
Western Route (Afghanistan–Pakistan)
- Despite a 93% decline in Afghan opium production after the Taliban ban, pre-existing stockpiles (13,200 tonnes) continue to fuel trafficking.
- Drugs enter India mainly through Punjab and Rajasthan.
Drone-Based Smuggling
- Drone trafficking cases increased from 3 (2021) to 305 (2025).
- Punjab accounted for:
- 298 cases
- 461 kg of narcotics seized
- Drones are increasingly used to evade traditional border surveillance.
- Similar incidents have also been reported in Rajasthan and Jammu & Kashmir.
Emerging Maritime Route
- Drug trafficking through the Gujarat and Maharashtra coastlines using fishing vessels and small boats is emerging as a major security challenge.
