The Biphasic model represents a significant step toward conceptual integration in the addiction sciences. Its emphasis on dynamic phase transitions, underlying neural circuitry, and behavioral expression offers both conceptual clarity and translational utility. By organizing complex neurobehavioral adaptations into a coherent, phase-specific framework, it provides a useful perspective through which to view the transition from early, voluntary drug use to uncontrollable, compulsive addictive behavior. Following empirical validation, the model has the potential to inform personalized approaches to addiction assessment, treatment, and prevention.
