A smoke stick is a cigarette. Many characters within the series smoke them. The first time they are mentioned is in Grimhall (subchapter). Most smoke sticks, due to the economic downturn brought on by the Black Sam plague, are "roll-your-own" smokers, however, some manufactured brands can be found at significant price. In Snowleaf (subchapter), Cavaneer Balt enjoys a pack of Jarlvils that he bought off the ticketmaster of the Circus Nomadia Supernal when it came through. Most smokes are made from the serio leaf.
Some smoke stick material is enhanced with exotic spices such as the sweet spice ingerus.
