Zyme

Zyme (name literally meaning "a ferment") is a synthetic drug that appeared in the 2050's in the USA. It quickly spread throughout the crisis-torn society and is considered a serious threat to public welfare. It is theorized to be the cause of an outbreak of mental illness. Washington D.C. considers introducing a zero-tolerance policy against recreational use of zyme. A zyme dealer named Rock is encountered in the Mole People tunnels under Battery Park.

Post-collapse greasel trainers utilize zyme to increase the aggressiveness of their pupils.
