Can You Get High From Eating Poppy Seeds?

Eating a poppy seed bagel or a slice of poppy seed cake will not make you feel high. The trace amounts of opiates on grocery-store seeds are far too small to produce noticeable psychoactive effects in a normal serving. But the fuller answer is more complicated than a flat “no,” because poppy seeds carry wildly variable amounts of morphine and codeine on their surfaces, and people who deliberately concentrate those alkaloids by brewing large quantities of unwashed seeds into tea have experienced full-blown opioid intoxication, dependence, and in some cases death.

How Opiates End Up on Poppy Seeds

The seeds inside the poppy capsule do not actually synthesize opium alkaloids themselves. The plant produces morphine, codeine, thebaine, and other compounds in the latex that lines the seed pod’s inner walls. Seeds pick up these alkaloids through contact with that latex, especially when pods are damaged by insects or during mechanical harvesting.

1PubMed Central. Update of the Scientific Opinion on opium alkaloids in poppy seeds Think of it like flour dusted onto bread rolls: the seeds are coated in residue from their environment, not generating it internally. This distinction matters because it means the alkaloid load on any given batch of seeds depends almost entirely on how the plants were handled, not on some fixed property of the seeds themselves.

Why Alkaloid Levels Vary So Dramatically

One of the most striking things about poppy seed research is just how inconsistent the opiate content is from one batch to the next. A forensic study measuring seeds from different origins found morphine concentrations ranging from 2 to 251 micrograms per gram, and codeine from 0.4 to 57 micrograms per gram.

2Journal of Forensic Sciences. Poppy Seeds: Differences in Morphine and Codeine Content and Variation in Inter- and Intra-Individual Excretion That means the highest-contamination seeds carried more than 100 times the morphine of the lowest. The variety of poppy matters a great deal here. Seeds from varieties bred primarily for pharmaceutical opium production tend to carry substantially higher alkaloid loads than those from varieties grown specifically as food crops. The European Food Safety Authority found that even seeds considered “low alkaloid” food varieties can exceed safe intake thresholds at high consumption levels, and seeds from pharmaceutical varieties routinely exceed those thresholds at ordinary serving sizes.

This variability is the core reason why blanket statements about poppy seed safety are so hard to make. The seeds you buy in a supermarket spice aisle have typically been washed and processed, stripping away most of the surface alkaloids. But seeds marketed online as “unwashed” can retain vastly higher amounts, and the buyer has no practical way to know where on that 100-fold spectrum a particular bag falls.

Normal Servings in Food

If you are eating poppy seeds the way most people do, sprinkled on bread, baked into pastries, or folded into fillings, you are extremely unlikely to notice any psychoactive effect. There are a few reasons for this. First, a typical serving is small, often just a few grams. Second, commercial food-grade seeds have usually been washed or heat-treated, which strips away a large portion of the surface alkaloids. Food processing can reduce morphine content by up to about 90%.

That said, “unlikely to feel anything” does not mean the alkaloids vanish entirely. A controlled study gave participants 45 grams of poppy seeds, roughly the amount you might find in a generously seeded roll or small pastry, and found that over 83% of the resulting urine samples tested positive for morphine at a 300 nanogram-per-milliliter cutoff.

4PubMed Central. Morphine and Codeine Concentrations in Human Urine following Controlled Poppy Seeds Administration of Known Opiate Content The morphine was clearly entering the body. It just was not enough, in most cases, to produce the drowsiness, euphoria, or respiratory depression associated with opioid use. You were absorbing opiates, but at doses too low to feel.

Poppy Seed Tea Is a Different Story

The picture changes entirely when people intentionally brew large quantities of unwashed poppy seeds into a liquid. Online forums have circulated “recipes” for poppy seed tea for years, and the practice has led to documented overdoses and deaths. The idea is simple: soaking a pound or more of seeds in water or an acidic liquid washes the alkaloids off the seed coats and into a drinkable solution. The problem is that this works, and works unpredictably.

A study replicating real-world brewing methods found enormous variation in the resulting morphine concentrations, ranging from roughly 1,800 to over 19,000 nanograms per milliliter depending on the seeds and technique used.

5Journal of Medical Toxicology. The Extraction of Morphine and Codeine by Brewing Poppy Seed Tea using Real-World Quantities and Methods Another analysis of home-brewed teas found that morphine concentrations in the seeds themselves ranged up to nearly 2,800 milligrams per kilogram, and concluded that lethal amounts of morphine can be rinsed from poppy seed coats by home-brewing methods.

6PubMed. Quantification of Morphine, Codeine, and Thebaine in Home-Brewed Poppy Seed Tea by LC-MS/MS

Case reports describe people who consumed poppy seed tea regularly ingesting several hundred morphine milligram equivalents per day, amounts comparable to high-dose prescription opioid use.

7PubMed Central. Opioid use disorder from poppy seed tea successfully treated with buprenorphine in primary care: a case report So to directly answer the title question: can you get high from eating poppy seeds? Not from eating them in food in any normal sense. But if you brew a concentrated tea from a large quantity of unwashed seeds, you are essentially extracting crude opium, and you can absolutely get high, dangerously so.

Why the Drug Test Problem Is Real

Even when the amount of opiates from poppy seeds is far too small to produce any subjective effect, it can be more than enough to trigger a positive urine drug screen. This has been documented extensively, and it remains a genuine source of real-world problems for people in drug-testing situations.

8Journal of Analytical Toxicology. Poppy Seed Ingestion and Opiates Urinalysis: A Closer Look

The concern is not limited to unusually large servings. A study examining common food products found that a single portion of certain commercially available poppy seed foods, including a kolach pastry and a cake made with grocery-store seeds, produced positive urine results not only at the typical clinical cutoff of 300 nanograms per milliliter but also at the Department of Defense’s higher cutoff of 2,000 nanograms per milliliter.

9Journal of Analytical Toxicology. Urine and hair drug test results associated with daily consumption of codeine-predominant poppy seed food products In the controlled study mentioned earlier, about a quarter of urine samples exceeded the 2,000-nanogram threshold for morphine after subjects ate 45 grams of seeds, with peak concentrations appearing around six to seven hours after ingestion and an elimination half-life of roughly seven hours.

4PubMed Central. Morphine and Codeine Concentrations in Human Urine following Controlled Poppy Seeds Administration of Known Opiate Content

This creates a significant headache for drug-testing programs. A positive result for morphine could come from heroin use, prescription medication, or a poppy seed muffin, and distinguishing between these sources is not straightforward. Some labs look at the ratio of morphine to codeine, or test for markers specific to heroin metabolism (like a compound called 6-monoacetylmorphine), but even these methods are imperfect.

10PubMed. The poppy seed defense: a novel solution One study found that about 18% of positive urine samples from poppy seed food consumption showed codeine-only results that mimicked the pattern expected from codeine drug use, making it difficult to tell the two apart based on concentrations and ratios alone.

11Journal of Analytical Toxicology. Poppy Seed Consumption May Be Associated with Codeine-Only Urine Drug Test Results

Forensic researchers have been working on better markers to solve this problem. One approach uses the fact that heroin is synthesized from morphine using acetic anhydride, which also reacts with thebaine (another poppy alkaloid) to create unique byproducts. A metabolite of one of these byproducts, designated ATM4G, has been proposed as a specific marker of illicit heroin use that would not appear after poppy seed ingestion.

10PubMed. The poppy seed defense: a novel solution Meanwhile, thebaine itself can serve as evidence that poppy seeds were consumed, since it appears in urine after eating seeds but is not present in heroin.

12PubMed. Urine thebaine determination by liquid chromatography tandem mass spectrometry after poppy seed consumption Neither marker has become standard practice across all testing labs, so the “poppy seed defense” remains a legitimate and sometimes unresolvable explanation for a positive test.

Does Baking Destroy the Opiates?

A common assumption is that the heat of baking must destroy whatever opiates are on the seeds. The evidence says otherwise. Researchers tested poppy seeds with both low and high alkaloid levels, subjecting them to dry heat, steam, water washing, and baking in a model bread product. Water washing was the most effective approach, reducing alkaloid concentrations by roughly 50 to 80%. Extended dry heat at 200 degrees Celsius cut morphine levels by about half after 30 to 40 minutes. But baking, the actual process of incorporating seeds into dough and putting them in an oven, had no significant effect on alkaloid concentrations.

13Journal of Agricultural and Food Chemistry. Concentrations of the Opium Alkaloids Morphine, Codeine, and Thebaine in Poppy Seeds are Reduced after Thermal and Washing Treatments but are Not Affected when Incorporated in a Model Baked Product

This makes sense when you think about it. Baking exposes the outside of a loaf to high temperatures, but the interior, where the seeds are embedded in dough, stays much cooler and wetter. The seeds are essentially insulated. Steam treatment was also largely ineffective. So if you are relying on your oven to neutralize the opiates in a heavily seeded cake or bread, that is not happening. The seeds that matter most for safety are the ones that were washed before you bought them, not the ones that were baked after.

Thebaine Poisoning

Most of the conversation about poppy seeds focuses on morphine and codeine, the classic opioid alkaloids that cause sedation and euphoria. But a less familiar compound called thebaine deserves attention, especially because it causes a very different kind of toxicity. Unlike morphine, thebaine is a stimulant to the nervous system. It can cause muscle spasms, rigidity, and convulsions rather than the drowsiness associated with typical opioid overdose.

An Australian cluster of poisonings from non-food-grade poppy seeds illustrated the danger vividly. All patients experienced muscle spasms, and the majority developed rigidity. Six experienced convulsions, five developed kidney injury and metabolic acidosis, and two suffered cardiac arrests. Thebaine was the dominant alkaloid found in their blood, and the severity of symptoms tracked with higher thebaine concentrations.

14PubMed. A cluster of acute thebaine poisonings from non-food grade poppy seeds in the Australian food supply Poppy seed tea consumption has separately been linked to reduced consciousness and respiratory depression, the more traditional opioid overdose picture.

15PubMed Central. Acute cardiotoxicity following ‘poppy seed tea’ consumption

The practical upshot is that someone brewing poppy seed tea faces not one but two distinct poisoning scenarios. If their seeds are high in morphine, they risk the classic opioid overdose: slowed breathing, loss of consciousness, and death from respiratory failure. If their seeds are high in thebaine, they risk seizures, muscle breakdown, kidney failure, and cardiac arrest. Naloxone, the standard opioid overdose reversal drug, addresses the morphine problem but does nothing for thebaine toxicity. And since the buyer has no way to know the alkaloid profile of any given batch, every cup of poppy seed tea is a gamble with unknown stakes.

Dependence and Withdrawal

People who drink poppy seed tea regularly can develop the same kind of physical dependence that occurs with prescription opioids or heroin. This is not a theoretical concern; it is well-documented in clinical case reports. Patients who tried to stop using poppy seed tea experienced severe withdrawal symptoms, including the classic constellation of muscle pain, insomnia, anxiety, sweating, and gastrointestinal distress, that drove them back to the tea.

7PubMed Central. Opioid use disorder from poppy seed tea successfully treated with buprenorphine in primary care: a case report These cases have been treated with the same medications used for other forms of opioid use disorder, such as buprenorphine combined with naloxone.

16PubMed Central. Opioid Use Disorder from Poppy Seed Tea Use: A Case Report

The pattern is often the same: someone discovers poppy seed tea as what seems like a natural, legal alternative to prescription painkillers or illicit opioids. Because it is made from a grocery item, there is an illusion of safety. But the pharmacology is identical. The morphine in poppy seed tea binds to the same brain receptors as pharmaceutical morphine or heroin-derived morphine. Your body does not care whether the molecule came from a prescription bottle, a syringe, or a teapot. The tolerance, dependence, and withdrawal that develop are biologically indistinguishable.

How Ancient Is This Problem?

Humans have been navigating the dual identity of poppy seeds, as both food and drug source, for thousands of years. Historical evidence suggests that poppies were used as food as far back as the Neolithic period, and there are indications that people in the Minoan civilization in the eastern Mediterranean were already exploiting the psychoactive effects of poppy juice.

17PubMed. The rules of drug taking: wine and poppy derivatives in the ancient world. VI. Poppies as a source of food and drug Throughout antiquity, poppies served simultaneously as a nutritious seed crop, a source of therapeutic compounds, and a poison. The tension between the food use and the drug use is not a modern regulatory invention; it is baked into the plant’s relationship with humanity going back millennia.

What has changed is the scale and accessibility. Ancient people who wanted to exploit the psychoactive properties of poppies had to grow the plants, score the pods, and collect the latex themselves. Today, anyone with an internet connection can order pounds of unwashed seeds and find detailed brewing instructions on forums. The alkaloid variability that was always present in the plant has become more dangerous in this context, because the volume of seeds involved in tea-making is so much larger than what anyone would eat in food, and there is no quality control on what arrives in the mail.

Who Should Be Especially Careful

If you face workplace or legal drug testing, even ordinary poppy seed foods can cause problems. The safest approach is to avoid poppy seed products entirely for at least 48 to 72 hours before a test. Given that the controlled study showed morphine peaking around six to seven hours after consumption and an elimination half-life of about seven hours, most of the alkaloid will have cleared within a day or two, but high-sensitivity tests could potentially still pick up trace amounts at the tail end.

4PubMed Central. Morphine and Codeine Concentrations in Human Urine following Controlled Poppy Seeds Administration of Known Opiate Content

Children and smaller adults reach the acute reference dose for morphine more easily, simply because the threshold is weight-based. The European Food Safety Authority set that threshold at 10 micrograms of morphine equivalents per kilogram of body weight, and noted that high consumption levels exceed this threshold in most age groups even for food-grade seeds.

1PubMed Central. Update of the Scientific Opinion on opium alkaloids in poppy seeds Traditional Eastern European pastries filled with poppy seed paste, some of which use hundreds of grams of seeds per recipe, represent a higher-exposure scenario than a few seeds sprinkled on top of a roll. For most adults eating commercially prepared poppy seed products in typical Western serving sizes, the exposure is low enough to be a non-issue for health, though the drug-testing risk remains.

Anyone considering poppy seed tea for pain relief, curiosity, or as a perceived “natural” opioid should understand that this is not a gray area. It is crude opioid extraction with uncontrollable dosing, and the outcomes range from mild intoxication to fatal overdose depending on variables no consumer can assess in advance.
