What is meant by addiction in the context of drug use?

Addiction, in the context of drug use, refers to an emotional or physiological dependence on a substance. This means that an individual develops a compulsive need to use a drug, despite its adverse effects on their life. The dependency can manifest both mentally and physically: mentally, an individual may feel an overwhelming desire to obtain and use the drug, which can lead to compulsive behaviors; physically, the body may adapt to the presence of the drug, leading to withdrawal symptoms when it is not available.

This definition underscores the seriousness of addiction as a chronic condition that affects brain pathways associated with reward and pleasure. Unlike temporary use or occasional recreational usage, which do not imply an ongoing or need-driven behavior pattern, addiction signifies a more profound health issue that often requires intervention and treatment. Additionally, a general dislike for a drug does not indicate any form of dependence; rather, it suggests an aversion to its effects and does not align with the concept of addiction.
