Fentanyl precursor chemical found in Nigerian meth lab; 10 arrested

Nigeria's National Drug Law Enforcement Agency (NDLEA) has uncovered a precursor chemical used in the production of fentanyl during the dismantling of a large-scale methamphetamine laboratory in Ogun State. The discovery was made in May 2026 within a forest spanning the Abidagba and Iroto communities.

The operation resulted in the arrest of 10 suspects, comprising three Mexican nationals and seven Nigerians. Authorities also seized 2.4 tonnes of methamphetamine and associated chemicals, with an estimated value exceeding 480 billion Nigerian naira. Fentanyl, a potent synthetic opioid responsible for numerous overdose deaths globally, is tightly monitored due to its high potency and the relative ease with which it can be manufactured from precursor chemicals.

With the seizure about two months ago and dismantlement of the meth lab in the deep forest of Ogun State, we relied on the forensic equipment to determine the precursor chemicals. “And we discovered one of the precursor chemicals was in fact for the production of fentanyl, which is bad news. Nobody wants to hear that word,”

NDLEA Chairman and Chief Executive Officer, Brig-Gen. Buba Marwa (retd.), revealed the findings while meeting with Derek Tolliver, Country Director of the U.S. International Narcotics and Law Enforcement Bureau. Marwa explained that the agency utilized forensic equipment, provided with support from the U.S. INL, to analyze the seized chemicals. This analysis identified one of the precursor chemicals as being suitable for fentanyl production.

"Nobody wants to hear that word," Marwa commented on the discovery of the fentanyl precursor, emphasizing that it constituted only a small portion of the total chemicals recovered. He stressed that without the modern forensic tools, this critical detail might have been overlooked, underscoring the importance of the agency's forensic laboratories, which were established and equipped with U.S. assistance. The presence of fentanyl precursors in Nigeria raises significant concerns about the potential expansion of synthetic opioid production and trafficking in the region.

It was just a small part of the precursor chemicals. Without these modern tools, that would have gone unnoticed,”
