Ant Nectar Addiction (Fallout: New Vegas)

Ant nectar addiction is a form of addiction which can occur in Fallout 3 or Fallout: New Vegas.

Fallout 3
While fire ant nectar is not addictive, ant nectar is, and cannot be cured by employing My First Laboratory, forcing the Lone Wanderer to employ a doctor to cure this form of addiction instead.

Fallout: New Vegas
It is possible to become addicted to ant nectar, though the 5% chance involved is one of the lowest addiction rates of any consumable in the game. The addiction rate is further reduced by the Chem Resistant, Old World Gourmet, and Big Brained perks, producing a very small 0.75% chance of addiction; however, the Courier will still become addicted with a 100% chance after frequent use due to the UMON effect, although the effect can be avoided through the use of the Logan's Loophole trait.

Bugs
Ant nectar addiction used to be incurable due to a bug, but this was fixed in Fallout: New Vegas patch 1.2.0.31x. The console command will immediately remove the addiction on the PC version.
