Addiction (Fallout: New Vegas)

Addictions are a type of negative condition

Characteristics
Addiction is permanent unless seen to by a doctor. Fixer will remove the player character's addictions permanently, the only drawback being the application of a temporary "nausea" debuff. With Old World Blues, the Sink Auto-Doc cures addictions for free as part of the basic physical exam. The Logan's Loophole trait prevents addiction entirely at the cost of limiting the Courier to level 30. Perks in Fallout: New Vegas such as Chem Resistant, Brainless and Old World Gourmet reduce addiction chance.

Bugs

 * Addictions in effect at the conclusion of the add-on Dead Money may become incurable.
 * Fixer can permanently remove addictions due to a scripting error.
 * Ant nectar addiction used to be incurable due to a bug, but this was fixed in Fallout: New Vegas patch 1.2.0.31x. The console command will immediately remove the addiction on the PC version.
