"Many experts believe the term 'narcoterrorism' was first used by former Peruvian President Belaúnde Terry in the early 1980s to describe terrorist-like tactics used against Peruvian law enforcement by Shining Path Marxist rebels. While narco-terrorism has no formal definition, it is generally used to describe activities by groups that use drug trafficking to fund terrorism. For the DEA, it is 'a subset of terrorism,' in which groups or individuals participate directly or indirectly in the 'cultivation, manufacture, transportation, or distribution of controlled substances and the money derived from these activities.'"
