Derived from the copper-based nine-fish of Centralia IV, Nitrolabe has several peculiarities compated to most drugs. The nine-fish secrete Nitrolabe as a poison that they use their spines to inject their attackers with. However, the poison only works on creatures who blood is copper-based. On creatures with iron-based blood, its effects are quite different.
Nitrolabe acts as a neural enhancer, increasing the speed and intensity of neural connections in the user to the extent that they are reduced to a twitching, orgasmic trance for the hour or so that a standard dose lasts. However, repeated usage causes neural connections to misfire or fail, causing pain, neural degredation and dystrophy, so that the user will over time come to require the drug in order to be able to function normally.
