"Bolivian Marching Powder" appears in Bright Lights, Big
City by Jay McInerney published in
1984. The main character describes the
brain and inner soldiers marching around once they've been stimulated with cocaine.
"All might come clear if you could just slip into the bathroom and do a little more Bolivian Marching Powder. Your
brain at this moment is composed of brigades of tiny Bolivian soldiers. They are tired and muddy from their
long march through the night. There are holes in their
boots and they are hungry. They need to be fed. They need the Bolivian Marching Powder." - Bright Lights, Big City, Jay McInerney, 1984
