Introduction to Addiction
Addiction is a complex psychological, behavioral, and sometimes physical condition in which a person becomes dependent on a substance, activity, or behavior despite harmful consequences. It affects the brain, emotions, behavior, relationships, physical health, and overall functioning of an individual.
In simple words, addiction occurs when a person loses control over the use of something and continues using or doing it repeatedly even when it causes damage to health, family life, education, career, or social relationships.
Addiction is not simply a lack of willpower or bad behavior. Modern psychology and medicine consider addiction a chronic mental and behavioral disorder because it changes the brain’s reward system, decision-making abilities, emotional regulation, and impulse control.
The person usually experiences strong cravings, compulsive behavior, emotional dependence, and difficulty stopping the behavior even after repeated attempts.
