Role of emotions in the background of addictions is a long-studied question. Clinical observations and comorbidity studies unambiguously indicate that psychoactive substance use and dependence are related to emotional problems as well. Emotional intelligence is a relatively new concept of the study of managing emotions. On the revelation of this construct's relationship with psychoactive substance use and dependence only a few studies have been carried out so far. Present study systematically reviews articles born between 1990 and October 1, 2010 dealing with the relationship of these two factors. Out of the identified altogether 54 studies, 37 fitted the criteria of analysis. Studies overall indicate that lower levels of emotional intelligence are associated with more intensive drinking, smoking and illicit substance use and also more likely correlate with internet addiction, bulimia, gambling and impulsive buying. According to their results, especially the components called "recognizing emotions" and "regulation of emotions" of emotional intelligence play important roles regarding substance use.
