"A narco-terrorist organization is an organized group that is complicit in the activities of drug trafficking to further or fund premeditated, politically motivated violence to influence a government or group of people. Although the DEA does not specifically target terrorists, some of the powerful international drug trafficking organizations we have targeted have never hesitated to use violence and terror to advance their political interests."
