Leo's Drug Habit

This is a minor quest in Megaton. Ask Doc Church about the people of Megaton, then use the speech or medicine dialog option and he will tell you about Leo Stahl's addiction to jet. Go to Leo Stahl in the Brass Lantern during the day or the Water Treatment Plant at night and ask him about his chem habit. Then use the speech dialogue option and he will quit his addiction and ask you to clean up his stash in the water treatment plant. You'll get 100xp, Karma, and Leo's stash key to a stash of meds and about 100 caps in the desk at the Water Processing Plant.

Alternatively, you can ask him about his habit, then ask to be hooked up. He will then sell you chems and stimpacks. If you ask him, "What's it worth to you to keep me quiet"?, you will receive bad karma in addition.

Leo's Stash
The contents of the stash always stay the same, but the number is random. The stash can have any number of:
 * Bottle Caps
 * Buffout
 * Med-X
 * Mentats
 * Psycho
 * Stimpak
