Regolith poisoning

Regolith poisoning is a disease afflicting those in Luna's lava tubes.^{[citation needed]} It is also common to the laborers living in regolith mining sectors due to breathing in regolith dust in the air. Symptoms include heavy coughing for extended periods of time. It is rather uncommon among the aristocrats & royal family as they hardly ever visit the outer labor sectors of Luna. Even so, Queen Channary died from it and Levana theorized that Channary often went to the outer sectors as she found them a convenient location for her many romantic exploits. This theory remains neither confirmed nor denied.
