Sri Lanka’s intensifying crackdown on narcotics, including the arrest and repatriation of alleged drug kingpins from the Middle East, India, Indonesia, and other locations, spells out the growing challenge of dismantling transnational trafficking networks that exploit maritime routes, international ports, and gaps in law enforcement cooperation.
Despite major drug seizures and enforcement operations, the flow of narcotics continues across international borders, generating enormous profits for criminal syndicates. The challenge is not confined to Sri Lanka or South Asia. Even the United States, with its extensive law enforcement resources and international partnerships, continues to grapple with drug trafficking and a severe overdose crisis.
The issue was highlighted during a virtual press briefing on Tuesday (27 October) by US Department of State Bureau of International Narcotics and Law Enforcement Affairs (INL) Assistant Secretary of State F. Cartwright Weiland. He said that 17 tonnes of illicit drugs had been seized across the Pacific, more than three times the quantity seized throughout 2025.
Weiland said that nearly 68,000 Americans had died from drug overdoses in the latest year for which figures were available, an average of almost 185 deaths a day. The figures explain the continuing difficulty of containing the US drug crisis, despite sustained enforcement efforts and international cooperation.
“This is a tragedy that is not only America’s problem; increasingly, it’s also the Pacific Islands’ problem,” he said, warning that criminal networks were expanding their reach across the region.
The implications extend to South Asia, where maritime trafficking, cross-border criminal networks, money laundering, and the movement of synthetic drugs present serious challenges to national security and public health.
South Asia’s exposure to int’l trafficking
Asked whether the US saw links between criminal networks targeted by the Regional Interdiction Partnership for Trafficking Intelligence, Disruption, and Enforcement (RIPTIDE) initiative and drug trafficking networks operating in South Asia, Weiland said that the connections were still becoming clearer. He referred to Chinese-based money launderers known to US authorities and links to Latin American criminal networks.
He also said that the US supported training for South Asian maritime law enforcement agencies to disrupt illicit trafficking networks across the Indo-Pacific.
Weiland said the INL had an established presence at major US embassies across Asia, including mainland Asia, and anticipated greater cooperation between teams dealing with different aspects of transnational crime. Experience gained in countries such as Thailand and Cambodia, where authorities are confronting scam centres and sexual exploitation, could help smaller Pacific nations respond to emerging criminal threats.
For Sri Lanka, the wider concern is how trafficking networks exploit the Indian Ocean, coastal landing points, commercial shipping, and container terminals to move narcotics between source countries and destination markets. The island’s position along major international shipping routes makes maritime intelligence, port security, and cooperation with regional enforcement agencies particularly important.
Colombo Port seizures expose scale of challenge
Recent seizures of drugs in Sri Lanka call for stronger measures to confront large consignments of synthetic drugs.
On 21 September, the United Nations Office on Drugs and Crime (UNODC) reported that 472 kg of crystal methamphetamine, valued at approximately $ 24.5 million, had been recovered from a shipment of towels at the Port of Colombo. The UNODC said that it had supported Sri Lanka Customs with advanced detection equipment, risk profiling, and intelligence-led targeting.
On 1 September, a separate operation at the Colombo International Container Terminals (CICT) uncovered nearly 463 kg of crystal methamphetamine, commonly known as ‘ice,’ with the Police estimating its street value at more than Rs. 8 billion. Three suspects, including two Pakistani nationals, were arrested. The Police Narcotics Bureau, the Central Crime Investigation Bureau, and Sri Lanka Customs participated in the operation.
The seizures raise questions about the effectiveness of cargo screening, intelligence-sharing arrangements, and the ability of authorities to identify the organisers and financiers behind consignments moving through Sri Lanka’s ports. Seizing drugs prevents them from reaching the market, but dismantling the networks responsible requires investigations into their supply chains, financial transactions, and international connections.
Sri Lanka’s regional cooperation is also developing. The fifth Director General-level talks between India’s Narcotics Control Bureau and Sri Lanka’s Police Narcotics Bureau were held in Colombo on 23 September. Discussions covered maritime trafficking trends, intelligence sharing, joint operations, fugitives, and coastal security. Representatives of the Indian Coast Guard, India’s Ministry of External Affairs, and the Tamil Nadu Police also participated.
The importance of such cooperation was underlined by an operation conducted by India’s Directorate of Revenue Intelligence on 16–17 October. Officers seized 137 kg of suspected crystal methamphetamine in the Nagapattinam District of Tamil Nadu, in a case involving an alleged plan to smuggle the drugs to Sri Lanka through a mid-sea transfer. Four people were arrested, according to the official account of the operation.
The case exposes the potential use of small coastal locations and offshore transfers to move drugs between India and Sri Lanka, bypassing conventional port controls. It also demonstrates why enforcement efforts on either side of the Palk Strait cannot be treated as separate national operations.
Synthetic drugs and changing trafficking patterns
The challenge is not limited to methamphetamine. On 5 October, Interpol reported the results of a multinational operation targeting synthetic drugs, precursors, and pharmaceutical products. The operation resulted in the seizure of 650 tonnes of substances and products, representing an estimated 89.6 million potentially fatal doses removed from consumer markets. It involved 17 participating countries, 7,247 seizures, and an estimated illicit value of $ 1.1 billion.
For the first time in an Interpol operation targeting synthetic drugs, ketamine seizures exceeded methamphetamine seizures by volume, with 17 tonnes of ketamine recovered. Interpol identified a broader pattern of increasing non-medical ketamine use, linked partly to lower prices and easier manufacturing. The operation also exposed trafficking in etomidate and DMT intended for use in vapes.
The findings are relevant to South Asian authorities as drug markets evolve beyond traditional narcotics. Enforcement agencies must be able to identify emerging substances, monitor precursor chemicals, and adapt to criminal networks that can rapidly change products, routes, and concealment methods.
US drug crisis and limits of enforcement
The US’s experience illustrates the limits of relying on seizures and arrests alone. Despite its extensive enforcement capabilities, the country continues to record tens of thousands of overdose deaths annually while criminal networks exploit international supply chains.
During the briefing, Weiland described the consequences of expanding criminal activity in Pacific Island nations, including pressure on psychiatric services, drug use among schoolchildren, cocaine washing ashore, and traffickers allegedly driving through checkpoints. He said that the same groups involved in trafficking drugs into the US were also contributing to criminal activity across the Pacific.
He warned that traffickers were exploiting the long distances between the US, Australia, New Zealand, and smaller Pacific nations, using gaps between jurisdictions to move illicit products through regional waters and ports. Some of these criminal networks also support scam operations targeting people in the US and across the Pacific.
Weiland pointed out the central problem in the international drug trade, which was the ability of organised criminal groups to operate across jurisdictions, while law enforcement remained divided by national borders and differences in legal systems, intelligence capabilities, and resources.
The US approach therefore combines domestic enforcement with overseas cooperation, training, and efforts to disrupt the networks that move drugs and finance criminal operations. However, the overdose figures cited by Weiland show that the availability of enforcement resources does not, by itself, eliminate the domestic consequences of the drug trade.
SL needs to move beyond seizures
Sri Lanka has maintained close cooperation among Sri Lanka Customs, the Police Narcotics Bureau, the Central Crime Investigation Bureau, the Navy, the Coast Guard, and relevant financial investigation authorities. Intelligence-sharing with India and other regional partners has also extended beyond identifying individual consignments to uncovering the organisers, financiers, maritime facilitators, and international distribution networks behind them.
The Government has now taken steps to set up drug detecting systems at commercial shipping and port operations. Colombo is a major regional transshipment hub and effective security measures must protect the port from criminal exploitation without unnecessarily disrupting legitimate trade. Intelligence-led inspections, risk profiling, and reliable cargo documentation have therefore become essential.
Drug trafficking is only possible through best practices with border control. It is connected to organised crime, money laundering, exploitation, and public health. Sri Lanka is facing a challenge mainly on the social consequences of addiction within the country.
Without such a coordinated approach, criminal networks will continue to adapt, even as individual consignments are intercepted and alleged kingpins are brought before the law.
