But they have struggled to implement important aspects of the deal, and coca production has only increased. After hitting a low in 2012, cultivation of coca — the base ingredient in cocaine — increased 134% between 2013 and 2016. While the FARC agreed to exit the drug trade, dissident members have remained, and criminal groups that have proliferated in Colombia are also jockeying for a piece of the trade.
