What is Addiction?
In the context of rehabilitation centers (rehabs), addiction is defined not merely as "bad behavior" or a lack of willpower, but as a chronic, relapsing brain disease. It is characterized by the compulsive seeking and use of a substance (or engagement in a behavior) despite devastating consequences to physical health, mental well-being, relationships, and career.

Rehabs approach addiction as a condition that hijacks the brain's reward system, making it nearly impossible for the individual to stop on their own, requiring professional, multi-faceted treatment.
Loss of Control
An addict loses the ability to moderate or stop using substances, even when they want to.
Compulsion
The urge to use becomes a primary drive, often bypassing rational decision-making.
Continued Use Despite Harm
A central definition is the inability to stop using despite knowing it causes health problems, financial ruin, legal issues, or destruction of relationships.
Chronic & Relapsing
Addiction is viewed as a lifelong condition, similar to diabetes or asthma, that requires ongoing management to prevent relapse.

Rehabs focus on the medical, neurobiological aspects of addiction:
Brain Chemistry Changes
Repeated substance use changes brain structure and functioning, particularly in areas related to judgment, decision-making, learning, memory, and behavior control.
Dopamine Hijacking
Addictive substances flood the brain's reward system with dopamine, creating a powerful "high" and conditioning the brain to prioritize the substance above all else.
Tolerance & Withdrawal
The brain adapts to the substance, requiring more to achieve the same effect (tolerance), and triggers severe, uncomfortable physical and emotional symptoms when usage stops (withdrawal).

Denial
Addicts often have a "blind spot" regarding their behavior, denying or rationalizing the consequences of their actions.
Coping Mechanism
Often, addiction is treated as a misguided, compulsive coping mechanism to escape stress, trauma, or emotional pain.
Distorted Thinking
Addiction creates cognitive distortions that trick the brain into believing the substance is necessary for survival.
Rehabs often make a distinction between these terms:
Abuse
A pattern of misuse that causes harm (e.g., getting drunk and driving).
Dependence
The body has adapted to the substance and requires it to function normally, often leading to withdrawal symptoms, but does not always include the compulsive, destructive behavior of addiction.
Addiction
The most severe form of substance use disorder, combining dependence with the inability to control the desire to use despite negative consequences.
Because rehabs define addiction as a complex illness, they do not view it as a moral failing.
Treatment, Not Punishment
The focus is on healing the brain and teaching new behaviors rather than shaming the individual.
Comprehensive Care
This includes medical detox (to manage withdrawal), behavioral therapies (such as Cognitive Behavioral Therapy - CBT), group counseling, and aftercare planning to manage the chronic nature of the disease.
