Coca is widely grown by peasant farmers in tropical developing countries that are the major source for production of cocaine as an addictive, dangerous drug.
Coca production has increased in recent years, along with the demand for drugs in the United States and Europe, under the sponsorship of major drug-traffickers usually in league with Governments. It is today one of the sole sources of livelihood for the vast majority of small farmers (most of whom used to work in mines that have since been shut down) non-governmental organizations in the Andean region.
