Dr. Kevin McCauley, in his video "New Perspectives on Addiction and Recovery," describes addiction as both a disorder of pleasure and a disorder of choice. By this, he means that addiction affects the brain's reward system, which alters how pleasure is experienced and how choices are made.

Tolerance occurs when the body becomes accustomed to a drug, requiring higher doses to achieve the same effect. Dependence develops when the brain adapts to the presence of the drug, leading to withdrawal symptoms when the drug is not taken. These physiological changes underscore the disease model of addiction by highlighting the body's physical reliance on the substance (Hart, 2022).
