              Abstract
              The possibility that individuals administer nicotine to selfregulate persistent negative affect has received interest as a possible explanation for the high prevalence of affectively vulnerable smokers Relatively overlooked however is the possibility that smokers might also selfadminister nicotine to elevate low positive affectRandom effects regression showed a significant anhedonia by conditionbytime interaction t181=−201 p = 004 supporting the hypothesis that anhedonia moderated nicotine’s effect on changes in positive affect Simple effect analyses showed a significant conditionbytime interaction among high anhedonic smokers t91= 247 p = 001 but not among less anhedonic smokers t91= 034 p = 073
