Nutmeg is a hallucinogen. The spice contains myristicin, a natural compound that has mind altering effects if ingested in large doses. Found that pretty interesting
I vaguely recall this being talked about during the "drug-crazed" 1960's.
Then again, back then a new rumor seemed to surface every week about something or other having the potential to get you high. Smoking banana peels was probably the most famous one!
