DEA is not really responsible for curing other continents and their countries of the drug trade. Technically, plants such as coca are used for other things and control farming markets across the globe should not be a high priority. Only entry of illegal substance into the country should be the US concern. I say stay within the US borders, we can't even travel to Peru without getting killed by Peruvians that are at war with the American government right now. Will Americans be able to travel abroad at all in the future? Seeing the wonders of Macchu Picchu and the Andes Mountains will be a thing of the past soon with this drug was.
