Chem Resistant is a perk in Fallout: New Vegas.

Effects

The perk has one rank and requires both level 16 and a Medicine skill of 60. It reduces the chance of developing an addiction to chems, such as Psycho or Jet, by fifty percent.

Notes

  • This perk synergizes well with the Chemist, Old World Gourmet, Brainless, and Day Tripper perks.
  • Having the Chem Resistant, Old World Gourmet, and Brainless perks results in a 72% resistance to addiction.
  • This perk is rendered useless if the Courier opts to take the Logan's Loophole trait.
  • Due to the game's UMON system, the player character will still have chance of becoming addicted after using a chem a certain number of times.
