This might happen even for drugs that don't give much pleasure, and even after symptoms of withdrawal are long gone.

False Pleasure Horny singal women Elmwood Park New Jersey Another surprising want of false 'liking' may be some brain 'pleasure electrodes'. But our findings indicate 'wanting' may be separable in the brain from 'liking', and that mesolimbic dopamine systems mediate only 'wanting'.
Conclusion Simple pleasures are not so simple.

Sensitization makes dopamine-related brain systems over-react subsequently to drugs and cues for them. But not all need actually cause pleasure.
That would be mere incentive salience 'wanting' -- without hedonic 'liking'. In drug addiction, the cause may be a nearly-permanent brain change known as neural sensitization, produced by addictive drugs.
They might well 'want' to activate their electrode again, even if it produced no pleasure sensation. Usually 'liking' and 'wanting' go together for pleasant incentives, as two sides of the same psychological coin. However, "Though sexual arousal was prominent, no orgasm occurred" p.

The pleasure gloss is actively painted onto mere sensory representations by limbic brain circuits. The pleasure of pleasure lies not in the intrinsic sensation itself, but in something done to it.
