Make it quick will ya, I'm coming down and I gotta get my fix.”— Paulie Cantelli
There are quite a few addicts in Fallout 3.
Leo Stahl (Megaton)Edit
Talking to the doctor in Megaton can get him to reveal Leo's crazy chem addiction, mostly jet. After this you can talk to him and talk him into quitting (good Karma). He will give you a key. Go to the Water processing plant, and there is a locked desk full of jet and money (along with some other chems).
Paulie Cantelli (Rivet City)Edit
Talk to Vera Weatherly and ask her about some gossip. She can tell you some interesting stuff. Mister Lopez is considering suicide, for example. She can also tell you that Paulie Cantelli is addicted to jet. Asking around confirms this. His room is filled with Jet, Psycho, and other chems. It is not free to take and you will lose Karma for doing so. However, you can avoid getting caught by simply closing the door behind you. While speaking to him, you have the option of offering him psycho. If you give him enough psycho you will soon find him dead (see Overdose (quest)).
Sierra Petrovita (Girdershade)Edit
When talking to him, he tells you he wants to cut your hair. Then a dialog option is available: "Are you taking jet over here?", to this he replies he has nothing else to do but get high. This is strange, considering how Murphy says that Jet has little effect on ghouls.
Zip (Little Lamplight)Edit
John Bear (The Pitt)Edit
Has a Radaway addiction along with his brother.
Grudd Bear (The Pitt)Edit
Has a RadAway addiction along with his brother.
Fallout: New VegasEdit
Chem addicts who have gone insane with their chems and are hostile to the player can be found predominately around the El Rey Motel. One is found in one of the rooms of the second level of the El Rey Motel. The others in the El Rey are dead, often lying on the floor.
Two non-hostile chem addicts are found at a camp fire just south of Fields' shack across the railroad tracks.
