Nutmeg is a common spice that can cause hallucinations if ingested in large doses. Nutmeg contains myristicin, a natural compound that has mind-altering effects if ingested in large quantities. The buzz can last one to two days and can be hallucinogenic, much like LSD. Visual, auditory, or sensory hallucinations do not set in until hours after ingesting the spice, so there is also the worry that someone could overdose, thinking they havent taken enough to feel anything. Nutmeg intoxication can cause a variety of symptoms, including drowsiness and hallucinations. It is important to note that consuming large amounts of nutmeg can be dangerous and should be avoided.
