⭐ Golden Triangle and Drug Trafficking Overview

The Golden Triangle is one of the largest opium- and methamphetamine-producing regions in the world. Criminal enforcement faces unique challenges:

Cross-border trafficking: Drugs move from Myanmar, Laos, and Thailand to India, China, and beyond.

Complex jurisdiction: Traffickers exploit porous borders, tribal areas, and weak law enforcement in remote regions.

International law: Enforcement relies on conventions like the 1961 Single Convention on Narcotic Drugs and bilateral treaties (e.g., India-Myanmar MoU on narcotics control).

Indian context: NDPS Act, 1985, combined with cross-border cooperation, is the main legal framework.

⭐ Key Principles in Cross-Border Drug Enforcement

Extraterritorial jurisdiction: India can prosecute if the act affects Indian territory or citizens.

Mutual legal assistance treaties (MLATs): Used to share evidence, track money, and arrest traffickers abroad.

Reverse burden under NDPS Act: If drugs are seized, accused must prove they were not knowingly in possession.

Procedural compliance: Search, seizure, and chain of custody are crucial for convictions.

Punitive approach: Courts impose severe sentences (life imprisonment or death) for large-scale trafficking.
