Gold Sickness

Gold Sickness, also called Dragon Sickness or Gold Fever, is an apparent mental change that happens to some characters in The Hobbit. It is caused by large amounts of treasure, particularly treasure hoarded by dragons. It results in greedy, illogical, and even violent behavior. It initially affected several members of Thorin's Company, the Master of Laketown, and Thrór. Fandom has adopted the trope to a large degree, and almost every work set during the reclamation of Erebor includes at least a mention of it.
==In Canon==
In fandom, most fanworks assume one of two options: either all the dwarves are all afflicted by gold sickness and Bilbo Baggins was not, or most of the dwarves were only mildly affected but Thorin was completely changed. (This latter option is influenced primarily by movie canon, specifically Battle of the Five Armies.) However, some fans pointed out that this was not consistent with the book:
There are also canonical variations in how strong the sickness runs in a particular character. In the book, Fíli, Kíli, and Bombur were said to be the least affected of the dwarves.The Hobbit, Chapter 13, "Not At Home". Some fanworks also vary the effects depending on the dwarf.
==Use in Fanworks==
Movie canon focused primarily on Thorin as the most gold-sick dwarf. Therefore, it's extremely common for Thorin to be the strongest affected in fanworks, especially works that ship Bilbo Baggins/Thorin Oakenshield, as a way to explain Thorin's willingness to banish and nearly kill Bilbo over the Arkenstone.
The Arkenstone itself frequently acts as a catalyst for gold sickness. This appears to be based on Thorin's obsession with it in movieverse and Balin's warning to Bilbo in Battle of Five Armies. Many fanworks blame Thrór's gold sickness on the stone. In some cases, the Arkenstone has some unique evil effect, rather than a general one; for example, The Line of Durin by imaginary_golux has the stone containing the soul of Smaug, which whispered lies to whoever sat on the throne. 
Other fans make the Arkenstone the focal point of Thorin's obsession with reclaiming his birthright, rather than the cause of it:
In fanworks focusing on other dwarves, the effects of gold sickness can take many forms. One common effect is for characters to forget to eat and sleep, instead spending all their time in the treasure hall. Sometimes characters say or do things they normally wouldn't, becoming more violent both verbally and physically toward one another. An example is oh by sarcasticasides, a fancomic where Nori threatens Dwalin with a knife, to his own shock.
