Which condition describes a compulsive need for habit-forming substances?

Addiction is characterized by a compulsive need to obtain and use habit-forming substances, despite harmful consequences. It involves a psychological and often physical dependence on the substance that alters brain function and behavior. Individuals struggling with addiction may experience cravings and a loss of control over their substance use, which can lead to negative impacts on their health, relationships, and daily functioning.

In contrast, amnesia refers to a loss of memory, which does not inherently relate to substance use. Akathisia is a state of restlessness and an inability to remain still, often associated with certain medications rather than a compulsive need for substances. Anaphylaxis is a severe allergic reaction that requires immediate medical attention and is unrelated to the compulsive use of items or drugs. Therefore, addiction is the most appropriate term to describe the compulsive need for habit-forming substances.
