If a creature already under Level 2 withdrawal has once again failed to either seek treatment or more of the substance by the next Daily Reset, then they will enter '''Level 3 withdrawal''', and the corresponding effects are applied instead. Level 3 effects are permanent until treatment or consumption of more.
If addicted, but currently under the effects of a corresponding substance from that addiction group, it can be considered that a creature is at a sort of "'''Level 0'''".
If an addiction has been developed, withdrawal effects can only be removed in one of two ways:
* Temporarily, by consuming more corresponding substances from the addiction group, in order to ward the withdrawal effects away; trading them for the substance's use effects instead. Effectively returns a creature to "Level 0", since it does not get rid of the addiction permanently.
* Permanently, with the help of a [[hospital room]], which may offer treatment to permanently get rid of addiction and addiction symptoms ('''1000 P$''' to cure one addiction; full treatment of multiple addictions may cost more).
