Lesai
a very addictive, highly illegal drug produced in the Zebitrope System, lesai was created from the purple mold which grew on the back of a certain species of lizards on Zebitrpoe IV. These lizards made their homes among some of the galaxy's most disgusting plantlife, making the harvesting of lesai a time-consuming and costly endeavor. The drug had a number of properties. It could eliminate the need for sleep in humans, as well as extending their lifespan by one-third. It also didn't adversely affect the human brain, so the hallucinations and delusions that resulted from other drugs were avoided. However, the drug made its addicts very mechanical and amoral, so that they acted without emotion, and didn't care about the consequences of their actions.
