The agency valued the seized drugs at more than N3.4 billion.
The National Drug Law Enforcement Agency (NDLEA) says it has seized more than 1.3 million tramadol and other opioid pills and capsules, as well as about 6,000 kilogrammes of cannabis, in a series of operations across the country.
Among those arrested was a 49-year-old man who allegedly posed as a Deputy Superintendent of Police and used a forged police identity card to move cannabis through security checkpoints in Delta State.
NDLEA operatives also intercepted 603.75 kilogrammes of Canadian Loud, valued by the agency at N1.811 billion, at the Tin-Can Island Port in Lagos.
In a statement on Sunday, the agency’s spokesperson, Femi Babafemi, said the arrest and seizure were recorded in Lagos, Edo, Niger, Delta, Ondo, Gombe and Imo states, as well as the Federal Capital Territory.
The suspect, Innocent Ekpe, was arrested on 16 September along the Benin–Onitsha Expressway in Asaba, Delta State, while travelling in a silver Toyota Sienna bus.
NDLEA operatives found 292.48 kilogrammes of skunk in the vehicle, according to the agency.
Investigators subsequently discovered that Mr Ekpe had allegedly been using the name Godwin Emeka and presenting himself as a deputy superintendent of police.
The agency stated that he used a forged police identity card to get through security checkpoints while transporting drugs between states.
A second suspect, Nduka Joseph, 39, was also arrested.
In Edo State, a raid on an auto-repair workshop along Agbor Road, Benin City, led to the arrest of the owner, Matthew Ossai, 45.
NDLEA explained that the workshop was being used to store illicit drugs. Operatives recovered 48 kilogrammes of Canadian Loud, 152 grammes of methamphetamine and a metal box from the premises.
At the Tin-Can Island Port, NDLEA operatives working with the Nigeria Customs Service and other security agencies found 1,200 parcels of Canadian Loud weighing 603.75 kilogrammes.
The consignment was concealed in 31 black jumbo bags inside two Toyota Sienna vehicles loaded into a 40-foot container shipped from Montreal, Canada.
The container arrived at the port on 12 September and was placed under surveillance following intelligence received by the NDLEA.
A joint examination on 16 September uncovered the drugs.
Along the Abaji–Abuja Highway, operatives arrested Aminu Isyaku, 23, and Jamilu Habibu, 25, on 18 September.
More than 1.1 million assorted tramadol tablets and capsules were recovered from eight sacks, alongside codeine syrup, methamphetamine and Exol tablets.
The consignment was allegedly being transported from Onitsha, Anambra State, to Mararaba, Nasarawa State.
In Lagos, Onyeka Ofor was arrested at his residence in Aguda, Surulere, on the same day. NDLEA said 48,900 tablets of tramadol 225mg were recovered from him.

The weapons were found inside a black travel bag, according to the agency.
In Ondo State, four suspects were arrested during a raid on a two-hectare cannabis farm in Ita-Ogbolu Forest.
