Unlike previous titles, addiction is permanent in Fallout 3. Each chem carries its own risk of addiction, as well as primary statistic debuffs once addicted. Chems also have what is called a "usage monitor effect," or "UMON," which is a value that accumulates with successive hits of the particular chem, raising the chance of addiction after each hit. A UMON value of 75 equates to an additional 1% chance of addiction, while a value of 175 equates to a 100% chance of becoming addicted.
