Original sentence: In fact, if the incentive salience associated with drug taking becomes pathologically amplified, the user may want the drug more and more while liking it less and less as tolerance develops to the drug's pleasureable effects.Proponents of this model argue that this explains the development of uncontrolled addictive behavior, which is not motivated by the hedonic value that caused acquisition of the habit in the first place.The incentive salience theory of addiction suggests that "liking" (hedonic value) of a drug may be dissociated from "wanting" the drug due to increased incentive salience
Edited sentence: In fact, if the incentive salience associated with drug taking becomes pathologically amplified, the user may want the drug more and more while liking it less and less.Incentive salience  is primarily affiliated with the "wanting" aspects of drug behavior, while the hedonic value (liking) is unaffected.This can lead to uncontrolled drug behavior which is not motivated by the hedonic value that caused acquisition of the habit in the first place
