Addiction, clinically referred to as substance use disorder (SUD) when involving drugs or alcohol, is defined by a compulsive need to engage in a behavior or consume a substance despite harmful consequences. It is not a sign of moral weakness or lack of willpower; rather, addiction is a medical condition that affects brain function and behavior.
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), outlines specific criteria to diagnose substance use disorders, including impaired control, social impairment, risky use, and pharmacological effects such as tolerance and withdrawal.
