Nutmeg psychosis - Definition

Nutmeg psychosis is an acute psychiatric disorder caused by the ingestion of around one to three whole nutmegs or an equal mass of ground nutmeg. Its symptoms include hallucinations, excitement, thought disorder, sense of impending death and agitation. Nutmeg is a toxic substance and a dosage of as little as 5g may cause a dry mouth, fast pulse, fever and flushing. It has amphetamine-like effects and may lead to the ingestion of large volumes of water. There is no specific antidote; the adverse effects wear off after 24 hours (or more) of rest.

The condition is almost always the result of deliberate experimentation in pursuit of the "legal high" or hallucinogenic effects, especially since nutmeg is easily purchased. Some cases have resulted in hospitalization; few who have experienced the effects of nutmeg poisoning recommend it as a "good trip" or repeat the experience.
