Chem Resistant (perk)

Chem Resistant is a perk in Fallout 3, Fallout: New Vegas, Fallout 4, Fallout: The Roleplaying Game and Fallout: The Board Game expansion Fallout: New California.

Fallout 3 and Fallout: New Vegas
Having the Chem Resistant perk reduces the chance to develop an addiction to chems, like Psycho or Jet, by 50%. This perk is rendered useless if the Courier opts for Logan's Loophole trait in Old World Blues. When stacking Chem Resistant with the Old World Gourmet and Brainless perks, it results in a 72% resistance to addiction.

Fallout 2d20
At rank 1, roll one fewer DC when determining addiction to chems, to a minimum of 0.

At rank 2, cannot become addicted to chems.

The level requirement increases by 4 after taking rank 1.

Fallout: New California
Chem Resistant is added to the game with the Fallout: New California expansion. Whenever a player character is about to become addicted by taking a drug, they can instead chose to take 3 damage instead. They can also chose to discard the perk card in order to lose the Addicted trait.
