Beginning around 2005, drug traffickers based in Latin America began to use Guinea-Bissau, along with several neighboring West African nations, as a transshipment point to Europe for cocaine. The nation was described by a United Nations official as being at risk for becoming a "narco-state". The government and the military have done little to stop drug trafficking, which increased after the 2012 coup d'état.
