The things you learn on the internet:
In low doses, nutmeg produces no noticeable effect on the body whatsoever. However, at higher doses (10g or more) it is a mild to medium hallucinogen, producing visuals and a comfortable effect almost similar to marijuana. There is a reason this is unpopular, though, as the effects last up to twenty-four hours after the initial peak, (approx. twelve hours after ingestion,) and have unpleasant side effects during the entire process, which linger for up to thirty-six hours. Nutmeg can also cause liver damage if used regularly in large quantities.
Nutmeg is extremely toxic when injected intravenously. Excessive consumption of the spice is also dangerous and can lead to death. Nutmeg has in the past been used as an abortifacient, and can also cause hallucinations when taken in excess, along with nausea, dehydration, and generalised body pain. Large doses (7.5 g or more in a single dose) are dangerous, producing convulsions and palpitations.
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 and reportedly few who have experienced the effects of nutmeg poisoning recommend it or repeat the experience.
