Addiction (Fallout 3)

Addictions are a type of negative condition

Gameplay
In Fallout 3, addiction is permanent. It can, however, be cured for a price in caps by visiting a doctor (like the one in Megaton). Owning a house in either Megaton or Tenpenny Tower enables no-cost addiction removal if the My First Laboratory house improvement is installed. Also, the healing archways in Mothership Zeta include removing addictions as part of their healing effects.
