Addiction encompasses physical and psychological dependence on substances or behaviors, leading to significant health challenges. Physical dependence results from physiological adaptations, causing withdrawal symptoms without the substance. Psychological dependence involves emotional reliance, often manifesting as behavioral changes and emotional withdrawal symptoms. Both types contribute to the global disease burden and require tailored treatment strategies.
