How Long Does Shroom Stay in Your System

Psilocybin mushrooms have been used worldwide for religious, spiritual, and recreational purposes. They are also called purple passion, magic mushrooms, or shrooms. This article will tackle shrooms, how they work within your body, and how long their effects can last in your system.

What Is a Magic Mushroom?

The psychoactive components of magic mushrooms are called psilocybin and psilocin. Psilocin is responsible for the hallucinogenic effects of mushrooms and is produced when psilocybin is broken down in the body. You will learn more about this process later in the article.

Psilocybin is a psychedelic chemical found in some types of mushrooms. Mushrooms containing psilocybin can induce psychedelic effects, from which the name magic mushrooms was derived.

Magic mushrooms can be found mainly in the wilds across the world. P. cubensis and other mushrooms in the genus Psilocybe are common sources. Nearly 100 species have been found to have different amounts of psilocybin.

Magic Mushroom Consumption

Psilocybin shrooms can be brewed into tea or eaten fresh or dried. However, be careful since consuming an excessive amount of them can result in adverse effects. Check out the most common methods of consuming shrooms below:

Dried Mushrooms

One of the ways that mushrooms can be prepared is by drying or dehydrating them. Dried magic mushrooms are perfect for microdosing since they can be preserved for a long time. Microdosing dried magic mushrooms require grinding them into a powder and then placing the product in empty capsules.

Edible Mushrooms

Foods containing either psilocybin or psilocin are considered magic mushroom edibles. Shrooms are pretty versatile and may be added to almost anything. Some users include magic mushrooms in their preferred dish to make the substance enjoyable and easier to consume.

Mushroom Drinks

Mushroom drinks are easy-to-consume shroom products. Many users are under the impression that consuming their magic mushrooms in a beverage like tea or hot chocolate makes them taste better and provides their stomachs with more soothing effects.

How Psychedelic Mushrooms Work

Once the psilocybin gets into your body, it changes into psilocin. The substance is believed to affect the amount of serotonin in the brain. Brain imaging with psilocybin showed that some parts of the brain have less activity than others. Also, increased communication in different brain parts is more likely to cause bizarre and altered perceptions.

It takes the body anywhere from 20 to 40 minutes to convert psilocybin into psilocin after ingesting psychedelic mushrooms. The effects of the drug become more noticeable as the concentration of psilocin in the blood rises. As the psilocin is eliminated from the circulation, the effects begin to lessen gradually.

How Long Shrooms Stay in Your System

About 13 hours is the average time it takes for 95% of psilocybin to leave the body. These are only averages. Please remember that many things affect how long these substances take to leave a person’s body.

It will take your body about 24 hours to break down the shrooms and eliminate the substance that makes you feel high. But it could take more than that, probably up to three days if you regularly use shrooms.

When you consume magic mushroom products, your body will transform the psilocybin into psilocin in 20 to 40 minutes. As the amount of psilocin in your bloodstream increases, you will soon start to feel the effects of the drug. The effects can last up to five to six hours and peak in about 90 minutes, with an average half-life of 50 minutes.

Potential Effects of Shrooms

The effects of psilocybin-containing mushrooms vary widely depending on many different factors. Some of the mental effects of taking shrooms are good, like feeling relaxed and reflective. However, there are also adverse effects, like nervousness, paranoia, or panic attacks.

Psilocybin has a lot of different effects on the brain. It activates serotonin receptors in the brain that control how you see, feel, and think. As a result, you may have distorted thoughts and see or hear things that are not there. Studies have also shown that psilocybin slows down the flow of blood to vital parts of the brain.

Possibilities for Shrooms Showing Positive on a Drug Test

Major drug testing companies do not look for shroom abuse in their specialized tests. However, some drug testing firms, like Quest Diagnostics and NMS Labs, still provide specialist tests for psilocybin and psilocin.

Blood Test

Five-panel drug tests are often used to check for marijuana, cocaine, and opioids. On the other hand, the nine-panel tests check for the use of barbiturates and benzodiazepines. None of the tests look at the mushrooms. 

Psilocybin testing in the blood is not common in most drug testing companies, but it can happen in some situations. The window for detecting shroom use is very short, so the test must be done within hours of use. Since psilocybin leaves the body almost entirely in 13 hours, it will be hard to be detected in drug tests after a day.

Urine Test

Urine tests will be different because they can tell if drugs are in your body for longer. Metabolites of other substances that leave the blood after 12 hours can still be found in the urine up to three days later. Some of these drugs are cocaine and amphetamines.


Drug testing companies can also test your hair to check if they contain psilocybin or psilocin. But these hair tests are rarely done unless someone tries to find out if they have used hallucinogens.

Like many other substances, magic mushrooms can stay in hair follicles for up to 90 days. But the test might need larger hair samples to find amounts of the substance that can be seen.

Factors Affecting Detection Time in Shrooms

Several things affect how quick and easy it is to detect psilocybin in your body. These include how often shrooms are used, how much is taken, and your genes. It should also be noted that some people can get rid of the drug faster than others.

The longer it takes for you to get high, the more shrooms you are likely to eat. Other things that affect how long it takes to detect shrooms in your system are:

  • Height
  • Weight
  • Race
  • Age
  • Smoking history
  • Alcohol use
  • Kidney and liver health
  • Existing medical problems

In addition, the metabolite will leave the body more quickly or slowly, depending on what kind of psilocybin mushroom you ate. There are more than 100 species of shrooms with different amounts of psilocybin, from 0.16% in Psilocybe liniformans to 1.78% in Psilocybe azurescens.

People over 65 tend to have less blood flow to their kidneys and liver, which makes it take longer for psilocybin to leave the body. Moreover, people with higher BMI, more excellent metabolisms, and more physical activity get rid of psilocybin faster.

Liver or kidney disease can make it take longer for psilocybin to leave the body. Ensure to drink more than enough water to help get rid of psilocybin faster.

How to Get Rid of Mushrooms From Your Body

High-performance liquid chromatography or tandem mass spectrometry tests urine samples for psilocybin and psilocin. Most of the time, it takes between four and eight days to get the report. The more shrooms you eat and the longer the psilocybin stays in your body, the quicker the substances will be detected.

Psilocybin can be gotten rid of faster by drinking water, but this is not enough if you want to pass a drug test. The only way to get rid of psilocybin from your body is to stop using it and give your body time to break it down and get rid of it.

Are Shrooms Addictive?

Even though shrooms are not addictive, they can cause adverse drug reactions like psychosis, paranoia, dizziness, and flashbacks. It can also sometimes lead to Hallucinogen Persisting Perception Disorder (HPPD), which can repeatedly cause visual hallucinations to come back.

Signs of a Shroom Overdose

If you are picking the shrooms in the wild by yourself, take a closer look at the mushroom and do in-depth research before ingesting them. Even mushroom hunters with a lot of experience can mistake a highly poisonous mushroom for the other one they were looking for. 

Moreover, eating too many mushrooms can poison your liver and result in death if you can’t get a liver transplant immediately. 

Most identified species of psilocybin mushrooms are unlikely to cause a physical overdose. However, some people may experience a “bad trip,” in which they become confused, lose awareness, and see or hear things that are hard to deal with on a psychological level.

To prevent bad trips, take smaller doses and only use shrooms when you are around a trusted friend or an experienced user. Before taking psilocybin, talk to your psychologist if you have a trauma disorder or an ongoing mental condition.

Magic Mushrooms FAQs

How long do mushrooms last after consumption?

The effects of shrooms usually wear off after three to six hours, though some people may continue to feel their effects for much longer.

How long do the effects of mushrooms on the brain last?

Psilocybin, the psychoactive component found in hallucinogenic mushrooms, is one example of a substance that can cause the mind to behave unexpectedly. They can distort your perspective of time, space, and self. These effects can last from 20 to 40 minutes and gradually vanish at least after 50 minutes.

Can mushrooms cause diarrhea?

Some magic mushrooms can cause diarrhea after consumption. The effects may appear immediately after eating, or they may not surface for anywhere between 6 and 24 hours. The terms gastrointestinal irritants, field mushrooms, or backyard mushrooms are used to refer to mushrooms that cause nausea, vomiting, diarrhea, and stomach pain.

Are mushrooms legal in Canada?

Yes. Psilocybin therapy was approved for use as a medical treatment for various mental health issues in 2021 after receiving exemptions from specific regulations. Health officials in Canada announced that the government would let licensed medical professionals request access to psychedelics for patients suffering from significant or life-threatening medical illnesses.


In conclusion, it takes 24 hours for psilocybin to be eliminated via the urine. Blood tests may take less than 24 hours for the traces of mushrooms to be removed. Lastly, it will take approximately 90 days before it becomes undetectable on your hair.
