Abrupt cessation syndrome:

Tolerance is the process by which a person's response to a drug diminishes over time, requiring higher doses to achieve the same effect. It does not directly relate to the cessation of drug use; rather, it describes a change in the body's reaction to a substance, making it an incorrect choice for describing abrupt cessation syndrome.

Addiction is a complex condition characterized by compulsive drug use despite harmful consequences. While addiction may lead to withdrawal symptoms upon cessation, the term itself does not specifically describe the phenomenon of abrupt cessation syndrome, making it an inaccurate choice in this context.

Dependency refers to the body's adaptation to a substance, resulting in a need for it to function normally. Although dependency can lead to withdrawal symptoms when the substance is suddenly stopped, it is not synonymous with the syndrome itself. Dependency describes the state of reliance rather than the specific syndrome of abrupt cessation.
