Regolith poisoning

Regolith poisoning is a disease that commonly afflicts those that go in Luna's lava tubes often.^{[citation needed]} It is also common to the laborers living in regolith mining sectors because of all the dust in the air. It is caused by breathing in regolith dust. The dust causes regolith poisoning. An example of a symptom of regolith poisoning is heavy coughing for long periods of time. It is rather uncommon among the aristocrats and royal family, because they hardly or never go to the outer, labor sectors of Luna. Even so, Queen Channary died from it. Levana theorized that this was because Channary was going into the outer sectors, however this theory was neither confirmed nor denied.
