Abstract
Research and theoretical perspectives of substance abuse are reviewed from an emotion theory perspective. Emotion permeates many important concepts in substance abuse research, such as trait anxiety, disinhibition, environmental cue reactivity, cognitive and mood regulation and behavioral motivation. Emotion theory and research may help integrate findings central to substance abuse such as predicting onset of use and describing end-state dysfunction. Increased incorporation of emotion concepts and measures in substance abuse research will increase the ecological validity of future research and provide more sophisticated understandings of substance abuse behavior. \[Quirk SW.
