Drug addiction
Drug addiction, also known as substance use disorder (SUD), is a chronic and relapsing condition characterized by compulsive drug seeking, drug use despite harmful consequences, and a loss of control over drug use. Addiction involves changes in the brain's structure and function, leading to a profound craving for drugs and difficulty in resisting the urge to use them. Drug addiction can affect individuals of all ages, backgrounds, and socioeconomic statuses, and it can have devastating effects on physical health, mental well-being, relationships, and overall quality of life.
