The Nigeria Customs Service (NCS) has dealt another major blow to illicit drug trafficking networks after operatives of the Federal Operations Unit, Zone A, intercepted narcotics, controlled pharmaceutical products and other prohibited materials valued at about N3.951 billion.
Three suspects were arrested in connection with the seizures, which Customs authorities described as the result of sustained intelligence-driven operations across border corridors, highways and other strategic locations within the South-West.
Rather than being merely another anti-smuggling operation, the interception has drawn attention to the enormous quantity of dangerous substances traffickers allegedly attempted to push through Nigerian communities and the potential consequences for public health and national security.
Comptroller of the Federal Operations Unit, Zone A, Gambo Aliyu, disclosed details of the operation during the formal handover of the intercepted items to relevant government agencies in Lagos.
According to the Customs chief, officers intercepted 5,669 parcels and 19 sacks of a synthetic strain of cannabis sativa weighing approximately 3,116.9 kilograms.
Other intercepted narcotics included different quantities of cannabis, popularly called skunk, as well as a wrap of crystal methamphetamine.
The operation also uncovered large quantities of controlled pharmaceutical products.
Customs listed the items as including 1,754 packs and 6,948 sachets of tramadol tablets in different strengths, 1,200 Hypnox tablets and 97 bottles of codeine syrup.
The narcotics and controlled drugs were subsequently handed over to the National Drug Law Enforcement Agency (NDLEA) for further investigation and necessary action.
Aliyu warned that the illegal movement of narcotics and psychotropic substances represents more than an economic crime, stressing that drug trafficking poses serious dangers to Nigerian youths, families and communities.
According to him, illicit drugs contribute to addiction, criminality, violence and other social problems, making anti-smuggling operations an important component of Nigeria’s wider national-security architecture.
The operation also produced another unusual discovery — four cylinders of high-grade mercury.
Each cylinder reportedly weighed 34.5 kilograms.
Customs said the substance is associated with small-scale gold-mining activities but poses significant environmental and health risks if improperly handled.
The mercury cylinders are expected to be transferred to the National Environmental Standards and Regulations Enforcement Agency (NESREA) for appropriate regulatory action.
The latest operation highlights the increasingly complex nature of smuggling networks, which are no longer restricted to conventional contraband but involve narcotics, controlled pharmaceuticals and potentially hazardous industrial substances.
Aliyu attributed the seizures to intelligence-led anti-smuggling operations and enhanced surveillance by Customs personnel.
He stressed that tackling organised smuggling requires effective collaboration among Nigeria’s security and regulatory agencies.
The Customs chief consequently advocated stronger intelligence sharing, coordinated enforcement and joint operations among relevant institutions to disrupt criminal networks.
The development comes amid intensified anti-smuggling operations by different formations of the Nigeria Customs Service.
In August, the Seme Area Command announced the interception of 3,300 cartridges of explosive materials alongside illicit drugs, expired food products and other prohibited goods.
Earlier in 2026, Customs at Apapa Port also announced multibillion-naira interceptions involving prohibited and controlled pharmaceutical products.
The latest N3.951 billion interception therefore underscores the scale of the challenge confronting Nigerian border and port authorities as criminal networks continually devise methods to move prohibited products across the country.
For Customs, however, enforcement must operate alongside its responsibility to facilitate legitimate international trade.
Aliyu assured that the Federal Operations Unit, Zone A, would continue deploying surveillance, intelligence and patrol operations against smuggling while ensuring that legitimate businesses are not unnecessarily obstructed.
The arrest of the three suspects could also provide investigators with an opportunity to look beyond the intercepted consignments and identify individuals or networks allegedly connected to their movement.
Authorities have not publicly established the suspects’ guilt, and they are entitled to due process as investigations continue.
The magnitude of the intercepted narcotics nevertheless reinforces concerns about the lucrative illicit-drug market and its potential impact on Nigerian communities.
Beyond the estimated N3.951 billion value of the seizures, authorities say the greater victory is preventing thousands of kilograms of potentially harmful substances from reaching the streets.
As Customs, NDLEA, NESREA and other agencies deepen collaboration, attention will increasingly turn from merely intercepting contraband to dismantling the financing, logistics and distribution networks sustaining illicit trade.
