Rhuludian Crystal
From Star Trek : Freedom's Wiki
Rhuludian crystals are a form of narcotic chemical commonly sought out in the Delta Quadrant, offered for sale to Chakotay and Tom Paris by trader Sutok near the Nekrit Expanse. (VOY: "Fair Trade")
According to the novel "Pathways" by reference originator Jeri Taylor, Rhuludian crystals are formed by dehydrating the leaves of a plant, probably similar to the formation of THC crystals on dried leaves of Earth marijuana. According to the story, when the Haakonians destroyed Rinax with a metreon cascade, survivor Neelix recalls turning to smoking this narcotic substance for solace.
