Addiction (Fallout)

Addictions are a type of negative condition $$

Gameplay
Selecting the Chem Resistant trait results in a 50% resistance to the addictive effect of individual chems, while the Chem Reliant trait doubles it, but with faster recovery. Chems which normally have a 10% addiction rate will be reduced to a 5% rate. If the trait is taken, however, chems will only last half as long.
