Describe symbolism in Naked Lunch by William S. Burroughs

The Mugwumps and the Reptiles present new and interesting images. Following the theme that drug addiction takes away an addict's humanity, the Mugwumps and Reptiles are described as inhuman creatures with strange bodies and behaviors. Each of these creatures represents something about the drug subculture and the ways in which the various groups interact with each other and use each other to fuel their own needs.
