You should see the show Cocaine Cowboys how CIA basically built the city of Miami with Columbians and flooded the city with Cocaine, millions of dollars were used to build skyscrapers, monuments, parks, basically economy skyrocketed, and when drug trade decreased so did economy, I mean car dealerships sank as well as jewelry stores, all private businesses felt burden....
I guess the drugs were being used to help the Contras in Nicuragua overthrow the Sandinasta Communist regime, that was really doing well during the Reagan administration...
