== Addiction vs. Dependence ==
The terms addiction and dependence are often used interchangeably, but they describe different conditions.<ref name="ref1" /> Dependence refers to a physical state in which the body adapts to a substance, leading to withdrawal symptoms if use is stopped or reduced.<ref name="ref1" /><ref name="ref2" /> Addiction is a chronic brain disorder characterized by compulsive substance use despite harmful consequences.<ref name="ref3" /><ref name="ref4" /> A person can be dependent on a substance without being addicted, and in some cases, addicted without being physically dependent.<ref name="ref1" />

Historically, the terms substance abuse and substance dependence were used. However, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), replaced them with the single diagnosis of "substance use disorder" to reduce confusion.<ref name="ref5" /> A substance use disorder is diagnosed based on 11 criteria and is graded as mild, moderate, or severe.

| '''Core Concept''' || A behavioral syndrome characterized by compulsive use, cravings, and an inability to control use despite negative consequences.<ref name="ref3" /> || A physiological state where the body adapts to a substance, resulting in tolerance and withdrawal symptoms upon cessation.
|-
| '''Nature''' || Primarily psychological and behavioral, involving changes in the brain's reward circuitry. || Primarily a physical adaptation of the body to the presence of a drug.<ref name="ref1" />
|-
| '''Withdrawal''' || May or may not involve severe physical withdrawal symptoms. Cocaine, for example, does not cause major physical withdrawal but is highly addictive. || Characterized by physical withdrawal symptoms when the substance is stopped or reduced.
|-
| '''Compulsion''' || A defining characteristic is the compulsive seeking and use of a substance, even with awareness of its harmful effects.<ref name="ref5" /><ref name="ref4" /> || Compulsive use is not a necessary component. A person can be physically dependent on a prescribed medication without being compelled to misuse it.<ref name="ref1" />
|-
| '''Tolerance''' || Often a feature, where increasing amounts of a substance are needed to achieve the same effect.<ref name="ref3" /> || A key indicator of dependence, as the body adapts to the substance.

=== Physical and Psychological Aspects ===
Dependence can be both physical and psychological. Physical dependence manifests through the physiological symptoms of withdrawal when a substance is discontinued. This is a natural bodily response to the prolonged presence of certain drugs, including many prescribed medications.

Psychological dependence involves an emotional or mental reliance on a substance, often tied to specific triggers such as stress or social situations.<ref name="ref1" /> Addiction is considered a psychological state, where a person compulsively seeks a substance due to powerful cravings and changes in the brain, regardless of physical dependence. For example, a person may be physically dependent on a prescribed opioid for pain management without having an addiction, meaning they do not experience cravings or compulsive drug-seeking behavior. Conversely, someone may be addicted to a substance like cannabis or cocaine without significant physical withdrawal symptoms.

=== Diagnostic Evolution ===
The DSM-5 moved away from the terms "abuse" and "dependence" toward the broader classification of "substance use disorder" to provide a more comprehensive understanding of the issue. This change helps to clarify that while physical dependence (specifically tolerance and withdrawal) is one of the possible symptoms of a substance use disorder, it is not the sole indicator. The current diagnostic model assesses a spectrum of behaviors and physiological symptoms to determine the severity of the disorder.
