• In the nineteenth century, cocaine was used as a “cure” for morphine addiction. However, cocaine is extraordinarily addictive. Starving experimental animals have been observed to choose cocaine in preference to food. Bolivia’s yearly income from cocaine exports has been estimated to be about a trillion dollars. North American cocaine dealers make ten times more than the Bolivian producers do. The peasants who grow the coca receive less than 1.5% of the value for which cocaine is sold in the United States.
