Over the past two years, major ports in north-western Europe have seen a notable drop in cocaine seizures. At first glance, this trend could be interpreted as a success for security policies. Ports such as Rotterdam, Antwerp and Hamburg, which for years had been the main gateways for cocaine entering the continent, have stepped up controls, international cooperation and anti-corruption measures. However, a more in-depth analysis reveals a more complex reality: the decline in interventions does not necessarily imply a reduction in trafficking, but rather a transformation of its dynamics.

Market indicators do not point to a shortage. In several Western European countries, wholesale and retail prices have fallen while demand remains stable or is growing. This suggests a scenario of oversupply, consistent with the sustained increase in production in countries such as Colombia. In other words, police pressure has not stopped the flow, but rather forced criminal organisations to innovate.
One clear adaptation is the change in the size of shipments. Large shipments of several tonnes, which are highly profitable but also very risky, have given way to smaller, more frequent shipments. This fragmentation reduces losses in the event of interception and makes detection more difficult using traditional intelligence patterns.
When surveillance increases at one point, trafficking shifts to other routes. This phenomenon, known as the waterbed effect, is already visible in Europe. The tightening of controls in Rotterdam, Antwerp and Hamburg has been accompanied by an increase in activity in ports in the north and east of the continent, as well as in the Baltic region and south-eastern Europe.
This redistribution entails additional risks: the arrival of new criminal players, increased violent competition, pressure on institutions with fewer resources and greater vulnerability to corruption. The result is not less cocaine, but a problem that is more dispersed and difficult to manage in a coordinated manner.
Criminal organisations have also become more sophisticated in their methods of concealment. In addition to trafficking in containers, practices such as hidden discharges into the sea under the hull of ships or the use of liquid and chemically modified cocaine to camouflage it as legal products are observed. Extraction and processing laboratories are also proliferating within European territory, a worrying sign of the illicit value chain moving closer to home.
This phenomenon is accompanied by a growing presence of Latin American criminal organisations in Europe, such as Brazil’s Primeiro Comando da Capital, the Clan del Golfo and the Sinaloa Cartel. Their establishment not only strengthens distribution networks, but also facilitates the transfer of knowledge, contacts and logistical capacity.
Given this scenario, the response cannot be exclusively national. Cooperation and information exchange initiatives are essential. Strengthening Europol’s mandate and enhancing Eurojust’s judicial tools are necessary steps to prevent local success from creating regional vulnerabilities.
The fight against drug trafficking is no longer just a matter of physically intercepting goods, but of intelligence, anticipation and shared strategic vision. The seizure data alone can create a false sense of control. The real challenge is understanding that this is a highly adaptable adversary.
Reducing interventions may seem like a victory, but it could actually be a mirage. Only through sustained cooperation, forward-looking analysis and a comprehensive approach to security can we prevent the problem from simply changing form while continuing to grow.
