A fan nickname for the substance that President Laura Roslin and Admiral William Adama, characters from Battlestar Galactica, can be seen smoking during a flashback in the season 3 episode, "Unfinished Business".
It has been confirmed in a podcast by creator Ronald D. Moore that this is a psychoactive substance and not a mere stimulant, such as nicotine. In the episode, Laura Roslin wanted to build a cabin by an area where the plant grows naturally, though it is not clear whether she was the one who discovered the psychoactive nature of the plant by trying to smoke it.
