TO THE EDITOR: We completely agree with Dr. Black and colleagues' suggestion that "primary" uncontrolled buyers are rare. The effect of serotonergic agents on compulsive buying in nondepressed subjects raises very interesting clinical and phenomenological questions. This effect can be understood as an "anti-obsessive-compulsive action." It corroborates a previously expressed hypothesis that suggests compulsive buying is related to the obsessive-compulsive disorder spectrum (1).
