Unfortunately, when an addicted person’s brain adapts by counteracting the effect of the drug, the brain then enters a state of deficit when the user is not taking the drug. If dopamine release is pleasurable, dopamine deficit is unpleasant. Ordinary life becomes boring and even painful without the drug. Nothing feels good anymore, except the drug. The addicted person is in a state of withdrawal, which will go away only if she can stay off the drug long enough for her brain to return to its default state (usually a few weeks).
