“With this Perk, you are less likely to be addicted to chems (50% less likely, actually), and you suffer half the withdrawal time of a normal person.”— Fallout Tactics in-game description
Flower Child is a Fallout, Fallout Tactics and J.E. Sawyer's Fallout Role-Playing Game perk. This perk later became Chem Resistant in Fallout 3.
With this perk, the player character is 50% less likely to be addicted to chems and the withdrawal time is half that of a normal person.
