What does withdrawal describe in the context of substance use?

Withdrawal in the context of substance use refers to the physical and psychological symptoms that occur when a person reduces or stops intake of a drug after prolonged use. This phenomenon is a direct result of the body adapting to the presence of the substance. When the drug is suddenly discontinued, the body can no longer function normally without it, leading to a range of uncomfortable or distressing symptoms.

These symptoms may include anxiety, nausea, sweating, tremors, and more, which can vary in severity depending on the substance used, duration of use, and individual health factors. The experience of withdrawal is a critical indicator of physical dependence on a substance. Understanding this concept is essential for recognizing when someone might be struggling with addiction and the potential danger involved in suddenly stopping substance use without professional support.

Other options related to tolerance, compulsive need, and relapse describe different aspects of substance use and addiction but do not directly define withdrawal.
