The effects of taking shrooms can last for up to 6 hours. Depending on How much do you take?, your body composition, and other factors, they may stay in your system for a day or two.

Psilocybin — the psychedelic compound that puts the so-called “magic” in magic mushrooms, or shrooms — can stay in your system for up to 24 hours. But that’s not set in stone.

The length of shrooms in your system depends on a lot of variables, from the species of mushroom you eat to Your age. and body composition.

These things affect how long shrooms are visible by a drug test.

The full timeline of shrooms includes how long their effects last and their detection window.

Healthline does not endorse the illegal use of substances, and we know that abstaining is always the safest approach. We believe in providing accurate and accessible information to reduce the harm that can occur when using.

It is difficult to say if a drug test is more sensitive than others because there are so many different types.

Most drug tests can not detect shrooms. More specialized tests may be able to do that. The detection windows can be different from test to test.

In general, though, shrooms don’t show up on most routine drug tests. The body also metabolizes shrooms too fast for them to show up in blood or saliva tests (unless the test is done within a few hours of consumption).

A 2021 review of research suggested that they’re barely detectable after 6 hours.

Urine tests

Most routine drug tests are urine tests. Most people’s bodies eliminate shrooms within 24 hours, making them undetectable by urine drug tests.

Hair follicle test

Hair follicle tests look for drug use within the past 90 days, but this type of testing isn’t common due to the cost.

“Some factors can affect how long shrooms stay in your system. You can’t control many of the factors.”

The time between ingestion and testing

The body can be rid of hallucinogens in a few minutes. The time between taking a shrooms and testing could be a factor.

The higher the chance that a drug test can be performed after taking a substance, the sooner it will be done.

Mushroom species

There are between 75 and 200 different species of mushrooms. The amount of hallucinogen varies from room to room.

The longer the shroom has the more it will stay in the body.

Method of use

Shrooms can be eaten fresh, dried, or in tea, and How do you consume them? affects their potency and how quickly it passes through your body.


How much you consume is a big factor. The longer shrooms will be in your body if you ingest more.


Your metabolism and kidney and liver function slow with age, which can delay the excretion of psilocybin from your body.

The longer shrooms tend to stay in your system as you get older. This goes for other substances as well.

Your body

Each body is different. Substances are not processed on the same schedule.

Things like your body mass index (BMI), metabolism, and water content all affect how quickly things are excreted from your body.

What’s in your stomach

When you take a dose of shrooms, how much food and liquid you have in your stomach is a big factor. The slower food moves through your system, the more you have to do shrooms.

hydration speeds up the excretion of psilocybin.

Other substances

Shrooms with other substances can cause unpredictable effects and time in your system.

If you drink alcohol or take any other substance with shrooms, it could affect how it’s processed by your body. There’s also the chance that the other substance will be picked up on a drug test, even if the shrooms aren’t.

It is important to consider the possibility that the shrooms you get could be contaminated with another substance.

Not really.

If you are trying to avoid detection, drinking water can help move it through your system a bit faster, but not much.

If you are worried about detection, then stop doing shrooms as soon as possible.

The effects of shrooms can usually be felt around 30 minutes after ingesting them, but it depends on How do you consume them?.

Fresh or dried mushrooms can be ingested on their own, mixed with food, or steeped in hot water or tea. In tea, shrooms can kick in as fast as 5 to 10 minutes after ingestion.

Shroom trips typically last between 3 and 6 hours, though some people may feel effects a lot longer. After your trip, you’re likely to have some lingering effects that can last into the next day.
