If it helps your body it can't be bad, right? The more you take the better you feel, thats a good thing, isn't it? Well, bad news, you got yourself addicted with the chem RadAway.
RadAway addiction is a form of addiction which can occur in Fallout, Fallout 2 and Fallout Tactics.
Using RadAway carries a 10% chance of becoming addicted. This addiction causes the player character to "feel nauseous" and reduces their Radiation Resistance by 20 for 10 days.
In the German and other censored versions of the games, the addiction images were removed and changed to normal Pip-Boy images.
