What are you wondering? Few countries have the climate to grow coca leaves under cover. Who else? Peruvians, etc. Colombians were and are still the biggest and most feared. Everyone else just brokers in cocaine - including Mexicans.
I think Peru and Bolivia are the biggest coca growing countries, but as far as criminal organizations go it's mostly Colombian criminal organizations with an increased presence of Mexican as well as Brazilian narco groups that operate in those countries. Brazilian groups are also operating from Paraguay these days. As far as drug shipments to Europe go, I think the role of Brazilian gangs is somewhat underestimated. Quite a, lot of cases can be traced back to Brazil. Dominicans too, but the Dominicans are high level brokers. I'd say the Colombians are still the biggest source of cocaine shipments to Europe.
