Nutmeg, the common kitchen spice ground from the seed of Myristica fragrans, contains psychoactive compounds that can produce hallucinations, euphoria, and a range of unpleasant side effects when consumed in large quantities. The practice of eating whole tablespoons of nutmeg for a high has been documented for over a century and resurfaces periodically, most recently through social media challenges aimed at teenagers. The experience is widely described as miserable by those who try it, and while deaths are rare, serious toxicity is real.
Why Nutmeg Gets You High
The psychoactive effects of nutmeg trace mainly to three compounds: myristicin, elemicin, and safrole. These are phenylpropanoids, a class of molecules found in various plants and spices. Of the three, myristicin draws the most research attention. Its chemical structure looks strikingly similar to certain amphetamine derivatives, which led researchers decades ago to hypothesize that the body might convert myristicin into something resembling MMDA, a compound related to MDMA (ecstasy). In the 1960s, a landmark experiment with isolated rat liver tissue confirmed that rat liver enzymes can indeed convert myristicin into MMDA.1Pharmacology. Evidence for the Biogenic Formation of Amphetamine Derivatives from Components of Nutmeg Whether this conversion happens at meaningful levels in living humans remains unproven, but the hypothesis has persisted for over half a century.
A more recent line of research points to a different mechanism altogether. Several compounds in nutmeg inhibit an enzyme called fatty acid amide hydrolase, or FAAH, which is responsible for breaking down the body’s own endocannabinoids. These are molecules your brain naturally produces that act on the same receptors as THC in cannabis. By slowing the breakdown of these natural cannabinoids, nutmeg compounds could effectively boost your body’s own cannabis-like signaling. Both purified nutmeg compounds and crude nutmeg extracts have shown this FAAH-inhibiting activity in laboratory studies.2PubMed Central. Phenolic compounds from nutmeg (Myristica fragrans Houtt.) inhibit the endocannabinoid-modulating enzyme fatty acid amide hydrolase3PubMed. Indirect modulation of the endocannabinoid system by specific fractions of nutmeg total extract The endocannabinoid hypothesis could explain why some people describe nutmeg intoxication as vaguely cannabis-like: dreamy, spacey, and somewhat sedating rather than the stimulant rush you would expect from an amphetamine-type compound.
In reality, nutmeg probably works through multiple pathways at once. The spice contains dozens of bioactive compounds, and the psychoactive experience likely reflects the combined action of several mechanisms rather than one clean pharmacological story. Researchers have identified that myristicin is metabolized by liver enzymes, with one particular enzyme (CYP1A1) playing a key role in forming a metabolite called 1′-hydroxymyristicin.4Journal of Agricultural and Food Chemistry. Metabolic Activation of Myristicin and Its Role in Cellular Toxicity The picture is messy, and the honest answer is that after decades of study, no one has fully nailed down exactly how nutmeg produces its effects in humans.
What Nutmeg Intoxication Actually Feels Like
If you are expecting a fun recreational experience, the overwhelming consensus from case reports and user accounts is that nutmeg delivers something closer to a prolonged, deeply uncomfortable illness. Symptoms span multiple body systems and can include hallucinations, agitation, drowsiness, dizziness, blurred vision, nausea, vomiting, diarrhea, rapid heartbeat, and swings in blood pressure.5PubMed Central. Nutmeg Intoxication: A Case Report Some people also experience anticholinergic effects like dry mouth, tremors, and further visual disturbance.6PubMed Central. Nutmeg Poisoning With Electrolyte Abnormalities: A Case Report
The combination of anxiety, restlessness, and hallucinations is the feature that sends most people to emergency departments. The hallucinations are not typically vivid or structured in the way you might associate with LSD or psilocybin. Instead, they tend to be disorienting, with a strong sense of confusion and sometimes paranoia layered on top. The gastrointestinal symptoms alone are often enough to make people regret the experiment well before any mental effects kick in, because you are essentially forcing your body to process a large bolus of volatile oils that irritate the gut lining.
How Much It Takes and How Long It Lasts
Toxic effects can begin with as little as five grams of nutmeg, which is roughly one to two teaspoons of the ground spice.7PubMed Central. Nutmeg Poisoning With Electrolyte Abnormalities: A Case Report People chasing a psychoactive effect typically ingest considerably more than that, sometimes two or three whole nutmeg seeds (around 10 to 15 grams). The amount of myristicin in any given batch of nutmeg varies depending on the plant’s origin, growing conditions, freshness, and storage, so there is no reliable way to dose it. This unpredictability is one of the reasons the experience is so inconsistent from person to person and even from attempt to attempt for the same person.
One of the most distinctive and frustrating features of nutmeg intoxication is its extremely slow onset. Symptoms typically begin one to six hours after ingestion, with some people not feeling much for three hours or more.8Toxicology Reports. Intoxication with nutmeg: A case presentation and analysis of Swiss poisons information center (Tox Info Suisse) enquiries 2014–2023 This delay leads to a common and dangerous mistake: people assume the first dose did not work and eat more, only to have both doses hit simultaneously hours later. The effects then last a punishingly long time, usually clearing within 24 hours but occasionally dragging on for up to 72 hours.9Toxicology Reports. Intoxication with nutmeg: A case presentation and analysis of Swiss poisons information center (Tox Info Suisse) enquiries 2014–2023 Spending two full days with nausea, confusion, and a racing heart is a real possibility, and there is no way to speed up recovery once the spice has been absorbed.
Who Actually Does This
Nutmeg abuse is not common, but it is not vanishingly rare either. Poison control data gives a sense of the pattern. A review of cases reported to the Illinois Poison Center over a decade found 32 nutmeg ingestions, of which about half were intentional.10PubMed Central. Nutmeg poisonings: a retrospective review of 10 years experience from the Illinois Poison Center, 2001-2011 Among the intentional cases, all of those who combined nutmeg with other drugs were between 15 and 20 years old. Texas poison control data from a similar period showed a comparable profile, with about two-thirds of nutmeg calls involving intentional abuse, predominantly by male adolescents.11PubMed. Nutmeg intoxication in Texas, 1998-2004
The pattern is consistent: nutmeg appeals mainly to teenagers and young adults, often because it is legal, cheap, and already sitting in the kitchen. It also attracts people in institutional settings like prisons or military barracks, where access to other substances is restricted. The practice tends to be a one-time experiment. Repeat users are unusual, in large part because the experience is so unpleasant relative to the modest and unreliable psychoactive payoff.
A notable spike in interest occurred in 2020 and 2021, when a “Nutmeg Challenge” went viral on social media platforms. The trend encouraged young people to film themselves consuming large doses, sometimes framing it as a weight-loss hack and sometimes simply as a dare.12Archives of Disease in Childhood. The ‘Nutmeg Challenge’: a dangerous social media trend Emergency physicians noted a bump in adolescent presentations during this period. The trend illustrates how a substance that most toxicologists consider a minor curiosity can become temporarily dangerous when amplified by digital culture and peer pressure.
Serious Risks and Fatalities
Deaths from nutmeg alone are extremely rare, and the medical literature contains only a handful of confirmed cases. One widely cited fatality involved a 55-year-old woman in whom postmortem blood testing revealed myristicin alongside flunitrazepam (a potent sedative), and the death was attributed to the combined toxic effects of both substances rather than nutmeg in isolation.13PubMed. Nutmeg (myristicin) poisoning–report on a fatal case and a series of cases recorded by a poison information centre This case underscores an important point: the greatest danger from nutmeg intoxication may come from combining it with other drugs. The Illinois poison control data echoed this, finding that the most seriously ill patient in their series was an adolescent who had taken nutmeg alongside other pharmaceuticals and required ventilatory support.14PubMed Central. Nutmeg poisonings: a retrospective review of 10 years experience from the Illinois Poison Center, 2001-2011
Even without other drugs in the mix, nutmeg can cause real medical emergencies. Electrolyte abnormalities, significant cardiovascular stress from sustained rapid heart rate and blood pressure swings, and severe dehydration from persistent vomiting are all documented complications. The confusion and disorientation can also lead to injuries if the person stumbles, drives, or makes other poor decisions while intoxicated. Because the effects last so long, the window of vulnerability extends well past the initial dose.
Safrole and the Long-Term Question
Beyond the immediate intoxication risk, nutmeg contains safrole, a compound that regulatory agencies around the world have flagged as a concern. Safrole has been shown to be a weak liver carcinogen in rodent studies and has demonstrated genotoxic properties, meaning it can damage DNA. In parts of Asia, oral cancer has been linked to safrole exposure through the practice of chewing betel quid, which contains the compound.15Flavour and Fragrance Journal. Review on safrole: identity shift of the ‘candy shop’ aroma to a carcinogen and deforester These findings led regulatory bodies worldwide to impose strict limits on safrole in food products.
For someone sprinkling a pinch of nutmeg on eggnog, safrole exposure is negligible and not a health concern. But people ingesting tablespoon-quantity doses of ground nutmeg are consuming far more safrole than regulators ever intended, and doing so repeatedly could theoretically elevate long-term cancer risk. This is not well studied in the context of recreational nutmeg use specifically, because there simply are not enough chronic nutmeg abusers to form a study population. The concern is extrapolated from animal data and from populations exposed to safrole through other routes.
Myristicin itself also has a toxicological profile beyond its psychoactive effects. Laboratory studies in mouse liver cells have shown that myristicin’s metabolite, 1′-hydroxymyristicin, causes cellular damage, and that antioxidant defenses in the cell help protect against this toxicity.16Journal of Agricultural and Food Chemistry. Metabolic Activation of Myristicin and Its Role in Cellular Toxicity When those defenses were experimentally depleted, the damage worsened. Whether the doses consumed by recreational users are enough to meaningfully harm liver cells in a living human is unclear, but it adds another reason to the already long list of reasons not to treat nutmeg as a drug.
What Happens at the Hospital
If someone does end up in an emergency department after eating a large quantity of nutmeg, the treatment is almost entirely supportive. There is no specific antidote for nutmeg intoxication.17The American Journal of Emergency Medicine. Acute nutmeg intoxication Emergency physicians focus on ruling out other life-threatening conditions, managing symptoms like nausea and rapid heart rate, ensuring adequate hydration, and monitoring the patient until the effects wear off. Activated charcoal may be considered if the patient presents early enough, but since nutmeg’s onset is delayed and people often do not seek help until symptoms are well underway, the window for charcoal is frequently missed.
Benzodiazepines are sometimes used for severe agitation or anxiety. Intravenous fluids help with dehydration from vomiting. Beyond that, the main treatment is time and observation. For most patients, the episode resolves without lasting harm within a day or two, though the experience is memorable enough that repeat visits for the same cause are uncommon.
How Doctors Detect Nutmeg Use
One complication for emergency physicians is that standard drug screening panels do not detect nutmeg compounds. Myristicin, elemicin, and safrole are not part of routine toxicology screens, so a person presenting with hallucinations, tachycardia, and confusion may initially be worked up for more common intoxicants. Diagnosis typically depends on the patient or a companion disclosing the nutmeg ingestion, which does not always happen. Adolescents in particular may be reluctant to admit what they have done.
Specialized forensic and research laboratories can detect nutmeg compounds and their metabolites in blood and urine. Gas chromatography and liquid chromatography methods have been developed that can identify myristicin, safrole, and elemicin along with their metabolites for at least 18 hours after ingestion of even moderate amounts.18Journal of Analytical Toxicology. Detection of Nutmeg Abuse by Gas Chromatography—Mass Spectrometric Screening of Urine Researchers have even developed models that can distinguish a large recreational dose from normal dietary use of nutmeg or related spices. Newer liquid chromatography techniques have uncovered additional metabolites and metabolic pathways, including sulfation, that older methods missed.19PubMed. Abuse of nutmeg seeds: Detectable by means of liquid chromatography-mass spectrometry techniques? Serum levels of the three major psychoactive compounds can now be measured and tracked over time in clinical settings when the diagnosis is suspected.20PubMed. Detection of major psychoactive compounds (safrole, myristicin, and elemicin) of nutmeg in human serum via GC-MS/MS using MonoSpin® extraction: Application in a nutmeg poisoning case
These tools are valuable for confirming cases in forensic investigations or research studies, but they are not available in the typical emergency room. In practice, clinicians rely on clinical history and the distinctive symptom pattern to make the diagnosis.
Nutmeg in Traditional Medicine
It is worth noting that nutmeg has a long history of use in traditional medicine systems, particularly in South and Southeast Asia, that has nothing to do with getting high. In Ayurvedic medicine, nutmeg kernel and its essential oil have been used for centuries to treat digestive complaints, joint pain, and respiratory conditions.21PubMed Central. Nutmeg (Myristica fragrans Houtt.) essential oil: A review on its composition, biological, and pharmacological activities The doses used in traditional preparations are generally much smaller than what recreational users consume, and the preparations are often oils or extracts rather than crude ground seed, which alters the pharmacological profile.
Modern pharmacological research has identified a range of bioactive compounds in nutmeg beyond the psychoactive ones, including compounds with anti-inflammatory, antimicrobial, and antioxidant properties. None of this validates eating spoonfuls of ground nutmeg for a high, but it does explain why the spice has maintained a place in traditional pharmacopeias across many cultures. The line between medicine and poison, as toxicologists like to point out, is almost always about dose.
