What is intoxication?

Intoxication refers to the temporary psychological and physical effects that occur due to the consumption of drugs or alcohol. When an individual is intoxicated, their cognitive and motor functions can be significantly impaired, leading to altered behavior, mood changes, and impaired judgment. This definition aligns perfectly with the selected answer, which emphasizes that the effects are significant and result from substantial drug use, thereby temporarily changing a person's functioning.

In the context of chemical dependency, understanding intoxication is crucial, as it differentiates between short-term effects experienced during substance use and long-term issues related to dependence or withdrawal. Other options describe more chronic states or conditions: a permanent change in cognitive functioning relates more closely to long-term cognitive impairment rather than immediate intoxication, while an ongoing condition of substance dependence and withdrawal state refer to chronic issues rather than the acute effects of intoxication.
