Which of the following is not a function of the National Drug Law Enforcement agency (NDLEA)

The function of the National Drug Law Enforcement Agency (NDLEA) that is not valid is "undertaking the registration of campaigns on drug trafficking." The NDLEA is a government agency in Nigeria responsible for controlling and regulating drug-related offenses, enforcing drug laws, arresting, investigating, and prosecuting drug traffickers, as well as carrying out enlightenment campaigns on drug trafficking to educate the public on the dangers and negative effects of drug abuse. However, registering campaigns on drug trafficking is not a function of the NDLEA. Instead, the agency focuses on preventing, detecting, and controlling the production, trafficking, abuse, and distribution of illicit drugs and psychotropic substances.
