Rokna Blue

Rokna Blue was an extremely potent and deadly narcotic that was extracted from a tree fungus on the forest moon of Endor. The smallest amount—no more than a microgram—brought exquisite bliss which lasted for hours but was otherwise considered fatally poisonous. Another side effect of using "the blue" was memory loss; one Rokna addict, Joreb Goss, could not remember anything from more than a year earlier.

It was popular in the time of the Black Fleet Crisis, but later became rare outside of the Moddell sector despite being cheaper than glitterstim.
