Ant Nectar Addiction (Fallout: New Vegas)

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

Fallout 3
Only Ant Nectar causes this addiction, Fire Ant Nectar is not addictive. Also note that this is the one addiction that cannot be cured by employing My First Laboratory. You must employ a doctor to cure this addiction.

Fallout: New Vegas
It is now possible to become addicted to fire ant nectar as well as the normal ant nectar, though the 5% chance is one of the lowest addiction rates of any consumable in the game. It is further reduced by Chem Resistant, Old World Gourmet and Big Brained  perks producing a very small 0.75% chance (likely rounded up to 1%) of addiction. The player will still become addicted with a 100% chance after frequent use, this is due to the UMON effect. The effect can be avoided through the use of the Logan's Loophole trait however.

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.
