"It can be argued that the drug of choice is resentment, the more destructive side of anger that has been repressed. Resentment feeds on itself in much the same way that heroin addicts must feed their addiction. We've all known those individuals who repeatedly put themselves in situations they can feel angry about, e.g., work or romance, because of the perverse (irrational and likely unconscious) "pleasure" they then derive from bathing in the toxic juices of resentment that they've created for their "fix." While one can argue that anger has its constructive side, resentment is much more insidious and therefore more damaging; one would be hard-pressed to describe any rationale for resentment being "good" - ever."
