How Long Do Magic Mushrooms (Psilocybin) Stay in Your System?

how long does psilocybin stay in your system

Given the widespread popularity and safety of magic mushrooms, it’s easy to see why more and more people are taking it.

Whether for recreation or for treating a certain mental health condition, psilocybin magic mushrooms are a famous classic psychedelic and for good reason: it has been proven to be safe, effective, and all-natural. It is currently being used for treating anxiety and depression, and it has shown to be beneficial for post-traumatic stress disorder, obsessive compulsive disorder, suicidal behaviors, and many more treatment-resistant conditions.

However, there are still some people who may be wondering about the possibility of detecting psilocybin use through drug tests, particularly for employment. Below, we’ll discuss how long psilocybin stays in your system.

Effect Onset

Psilocybin, the hallucinogenic mushroom found in certain mushroom species, are consumed in a variety of ways. It can be consumed raw, dried, in the form of a tea, or processed into an edible – such as the more common magic mushroom-infused chocolates.

It usually takes anywhere from 10 to 40 minutes until one starts to experience its psychedelic and hallucinogenic properties, though the onset is affected by the consumer’s physiology and experience. For example, if you consume dried mushrooms on an empty stomach, the onset will usually be much quicker. Many people also experience nausea and vomiting before or during a shroom high, though this is quite normal since mushrooms can be tough on the stomach. If you have a sensitive stomach, it’s recommended to take mushrooms an hour or two after a meal.

During the interval, this is when the body converts the psilocybin into psilocin, the active compound that binds to the serotonin receptors. Other factors that affect how long the high begins include your body weight as well as the type and potency of the mushrooms.

Effect Duration

Magic mushroom trips can last from 3 up to 12 hours, depending on how much you took and how potent they are. Some things you can expect from a mushroom high are hallucinations, dizziness, nausea, or even a sense of calm and peace. The peak of the high will usually occur 60 to 90 minutes after you have ingested the psilocybin.

However, if you take a strong dose of mushrooms close to bedtime, it’s common to still feel some of its effects the following day. Psilocybin can stay in the human body for up to 24 hours, after which it’s naturally excreted.

Can Magic Mushrooms Show Up on a Drug Test?

Common drug tests used in employment don’t usually look for the presence of psilocybin since they usually look for the presence of THC compounds in marijuana, benzodiazepines, cocaine, or opiates. That said, there are also more specialized drug tests that can look for psilocybin, peyote, LSD, and mescaline through urine or hair samples.

The good news with magic mushrooms is that the body metabolizes it very quickly. After around 24 hours, there should be no detectable traces of mushrooms in your urine though it is no longer detectable in the blood in less than 24 hours.

How long or short it takes for psilocybin to be excreted from the body will also depend on several factors:

  • Weight: Individuals who have a higher body mass will take longer to get rid of psilocybin than those with a lower body mass

  • Age: Older people aged 50 and up already have a reduced blood circulation in the liver and kidneys, which will affect how long it takes for the body to eliminate psilocybin

  • Hydration: Drinking lots of water before, during, and after your trip can help speed up natural excretion

  • Fitness: Active individuals with faster metabolism can get rid of psilocybin (as well as other drug compounds) quicker than those who don’t exercise

  • Kidney and liver health: If you have any kind of kidney or liver disease, this can reduce the time it takes for getting rid of psilocybin

Now, if you are buying magic mushrooms from a dealer that isn’t trustworthy, you could risk the shrooms being contaminated by other drugs. Always buy your magic mushrooms from a reputable dealer unless you are knowledgeable about foraging and sourcing it yourself. If you consume contaminated mushrooms that have been tainted with other drugs, you could be in for a surprise if you take a drug test for work.

Also, keep in mind that hair follicle drug tests are more specialized and capable of looking for the active compounds in drugs for a much longer time. It’s estimated that hair follicle drug tests can look for drug compounds, including psilocybin, for up to 90 days after you’ve consumed it. But since these high-end tests cost a lot more money, they aren’t usually utilized by employers or federally-regulated programs.

How To Flush Out Psilocybin

Magic mushrooms are excreted and cleansed out of the body on its own fast. But if you are worried about lingering after effects or you want to get rid of it quicker, simply take a lower dose of it. If you are aware of any upcoming drug tests, be sure to abstain for at least a few days before it.


Magic mushrooms have excellent therapeutic benefits, though unfortunately some of us are employed in jobs that may still test for them. Understanding how long magic mushrooms stays in the system will help you plan your trips to avoid getting a positive drug test.
