Indian security and narcotics agencies are confronting a multi-front drug crisis, as fresh data from the Narcotic Control Bureau (NCB) reveals a sharp rise in pharmaceutical drug diversion, the exploitation of national highway corridors for trafficking, and deepening links to international cartels operating through the Golden Triangle. The threat is no longer confined to border states — it now cuts across Bihar, West Bengal, Assam, Tripura, Punjab, Haryana, and the northeastern frontier.

Pharmaceutical Diversion: The Hidden Pipeline

Among the most alarming emerging trends is the systematic diversion of legally manufactured pharmaceutical products into illicit networks. West Bengal leads the country in codeine-based cough syrup seizures, with agencies recovering 27.50 lakh bottles between 2020 and 2024, according to the NCB. In Assam, the same five-year window saw the seizure of 1.72 crore tablets — the highest tablet-seizure figure recorded in any single state nationally. Tripura also reported significant recoveries of both tablets and codeine-based syrups during this period.

Officials say this trend reflects a deliberate exploitation of India's large generic pharmaceutical manufacturing base, where diverted medicines are re-routed into street-level drug markets. The NCB has flagged the need for tighter supply-chain monitoring across chemical and pharmaceutical supply lines.

Haryana's Highway Corridor: A National Transit Hub

Recent seizure data has brought Haryana into sharp focus as a critical narcotics transit corridor. According to an Intelligence Bureau official, the state's extensive road and rail connectivity makes it a preferred route for traffickers linking Delhi-NCR, Punjab, Uttar Pradesh, Rajasthan, Uttarakhand, Himachal Pradesh, Jammu and Kashmir, and Ladakh.

Between 2020 and 2024, agencies operating along this corridor seized 1,465.99 kg of opium, 51,074 kg of marijuana, and 74,828 kg of poppy husk. The NCB has identified the need for extensive highway interdiction operations and improved logistics monitoring to choke these supply lines.

Manipur and the Golden Triangle Threat

Officials describe Manipur as a high-value trafficking risk zone, directly linked to the Golden Triangle — the convergence of Myanmar, Thailand, and Laos — where powerful international cartels produce and export synthetic drugs and heroin into India. The Manipur route is characterised by a higher density of foreign operatives compared to other corridors, officials noted.

Heroin accounts for the highest volume of seizures on this route, according to the NCB. The involvement of international players adds a layer of operational complexity that domestic interdiction alone cannot address, officials say.

Punjab: The Epicentre, With a Cross-Border Dimension

Despite the spread of trafficking across multiple states, Punjab remains the most acute flashpoint. Over the five-year period from 2020 to 2024, agencies in the state arrested 62,245 persons and seized 5,942.29 kg of heroin. Officials have stated that Pakistan's Inter-Services Intelligence (ISI) has been actively pushing drugs into Punjab and has reportedly established an entrenched network in the state.

This comes amid longstanding concerns that cross-border narcotics trafficking into Punjab is being used as an instrument of economic and social destabilisation, according to officials.

Regional Consumption Patterns and the Road Ahead

NCB data also maps distinct regional preferences in drug consumption. Heroin dominates in the northeastern states; Delhi sees high demand for cocaine, mephedrone, and ephedrine; Jammu and Kashmir records the highest preference for heroin and hashish; Bihar and Jharkhand lean toward opium and poppy; and Odisha shows the highest consumption of marijuana.

Officials say the scale of the challenge demands intensive coordination between Central agencies, state police forces, and the Intelligence Bureau. The Union Government's declared 'drug-free India' campaign has accelerated enforcement, but officials acknowledge that tackling international cartels, pharmaceutical diversion, and highway networks simultaneously will require sustained, multi-agency effort. The next phase of operations is expected to focus on highway interdiction, supply-chain audits of pharmaceutical firms, and enhanced intelligence-sharing with neighbouring countries.
