Which of these is the BEST example of a substance-induced disorder?

A substance-induced disorder refers to a clinical syndrome that is directly related to the ingestion of a psychoactive substance. In this context, methamphetamine psychosis is a condition that emerges as a result of the effects of methamphetamine use. It can include symptoms such as hallucinations, delusions, and severe agitation, all of which are attributed directly to the intoxication or withdrawal from the substance.

This diagnosis illustrates how specific substances can lead to acute psychiatric symptoms that significantly impair an individual's mental state and functioning. In this case, the use of methamphetamine can cause psychotic episodes, which are characterized by a clear link to the substance itself, confirming the designation of a substance-induced disorder.

Other options may represent conditions associated with substance use, but they do not fit the definition of a substance-induced disorder as closely. Alcohol intolerance typically involves a physiological response rather than a disorder affecting mental status. Alcohol withdrawal pertains to the physiological aspects of withdrawal from alcohol use, while methadone dependence describes a chronic condition of dependency rather than a specific acute disorder induced by a substance. Therefore, methamphetamine psychosis stands out as the best example of a substance-induced disorder.
