Half of Colombia’s cannabis production is concentrated in the northern part of Cauca province, and 50% of that is grown in Corinto alone. Police estimate 100 hectares of land in the municipality are dedicated to growing weed; local farmers reckon the real number could be twice that. So when Colombia recently legalised marijuana for medical and scientific purposes, farmers in Corinto figured they had a corner on the cultivation market. A group of farmers came togetherto create Caucannabis, a cooperative that aims to be a prime supplier to companies hoping to cash in on Colombia’s new legal marijuana business.
