Kessel pure, a type of spice, borrowed its designation from the planet Kessel, which was renowned for its spice exportation. In 9 BBY, within the Imperial Era, a young human named Tetha Grig endeavored to trade spice with the Jedi Obi-Wan Kenobi on the planet Daiyu, presenting various forms of the narcotic, one of which was Kessel pure. Kenobi refused the offer and subsequently departed.
The initial reference to Kessel pure occurred within the second episode of the live-action television show Obi-Wan Kenobi, broadcasted on Disney+ on May 27, 2022.
