12. Bolivia
People treated for drug abuse per million: 2,329.8
Up next on our list of countries with the biggest drug problems in the world is Bolivia, that is the third largest producer of coca (the raw material used to make cocaine) in the world. This country faces numerous security challenges especially due to coca cultivation and transnational drug trafficking. It is safe to say that majority of security problems stem from drug-related issues. Bolivia withdrew from the global drug treaty in 2011 and coca consumption is legal since then. Bolivia is also one of the centers for drug trafficking especially for locally produced cocaine and cocaine that is imported from Peru. The majority is exported to Brazil, the second largest market of cocaine in the world and some quantities are exported to Argentina, Chile, Paraguay and even Europe.
