How Long Do Shrooms Stay in Your System?

Shrooms will stay in your body as an active drug for a varying amount of time

How long do shrooms stay present in your system? Well, it depends on what we mean by “in your system.”

Magic mushrooms, also known as “shrooms”, pass through your digestive tract. They also pass through your mind.

They’re traceable for a certain amount of time in your blood, hair, and urine.

They also have the potential to change your life! So, how long do shrooms stay with you? “Forever” is a fair answer, from that perspective.

Speaking more in terms of their physical presence, a number of other factors play a role. These include dose size and potency, along with the user’s weight and age.

Effects Over Time from Different Psilocybin Doses

You’ll typically start to feel the effects of shrooms after about half an hour. During this time, the psilocybin and psilocin contained in the mushrooms begin to act as a drug.

The effects of a larger dose can be much more potent than a smaller dose.

The sensations will gradually increase, generally peaking after about 90 minutes. They will then slowly fade away.

You’ll likely be “feeling” it for around four hours with a microdose, and five or six hours with a larger dose.

Some degree of effect tends to linger throughout the day and even the next day. These aren’t really physical effects — it’s more that if the experience opens up your mind to new feelings and ideas, they’ll stick with you.

That effect will be more distinct with new users and with larger doses.

What Factors Influence the Effects and Timing of Psilocybin?

Different variables will determine how strongly and for how long you experience the effects of shrooms.

Here are some of the factors that can increase the strength and duration of psilocybin in the human body:

  • The potency of the shrooms — this varies based on variety, preparation, and delivery method.

  • Your age — metabolism, kidney, and liver function slow down with age, so shrooms stay in the system longer for older users.

  • Your weight — people with a larger body mass will move shrooms more quickly through their system.

  • Your prior experience — your first few times using shrooms will likely be more intense than those that follow.

After a strong shroom trip, you’ll typically feel “like yourself” again after 24 hours. With microdose use,  you’ll never really not feel like yourself.

It’s important to know what to expect from different doses of shrooms. That way you can decide what’s right for you. Learn more about each dosing level with our dosing guide.

Half-Life of Psilocybin

The duration of a substance’s effect is often discussed in terms of its half-life.

Half-life refers to the amount of time that it takes for the concentration of a drug in the body to reduce to 50 percent of its starting dose. In other words, how long it takes for the body to eliminate half of what you consumed.

The half-life of psilocybin is about 50 minutes. However, half-life should not be confused with the effects you feel. The peak effects of magic mushroom use extend well beyond the 50-minute mark.

Long-Term Effects of Psilocybin Use

Physically speaking, you won’t notice much in terms of long-term effects.

Shrooms have extremely low-level toxicity. Therefore, there aren’t any harmful lingering effects to worry about.

Psilocybin doesn’t tend to stick around for too long in your system. We’ll get more into this below when we discuss drug test implications.

The long-term effects you’re more likely to experience concern your mental health and lifestyle. That’s because shrooms can bring about a variety of benefits and new experiences.

Psilocybin Effects Over Time From Different Dose Sizes

Psilocybin may not stick around in your system. But that doesn’t mean it can’t have a lasting effect on you.

With larger doses and “tripping” experiences, use often brings about a deeply spiritual experience. This can involve an enhanced sense of connection or a burst of new ideas.

Tripping experiences can be profound. In fact, research has shown that psilocybin use is often considered one of the high points of a person’s spiritual life.

With microdosing, the experience is less intense. But it’s just as valuable. Microdose use can bring about a variety of daily benefits, such as relief from anxiety or depression.

We’re still learning about the benefits of microdosing. There is exciting research being conducted about smoking cessation. A variety of other research areas are just opening up. These include the exploration of various benefits associated with creativity and focus.

All of these benefits might end up as “long-term effects”. That goes for both tripping experiences and microdosing.

Physically speaking, however, psilocybin is basically in and out. That applies to any dose size. Magic mushrooms do not leave a significant physical after-effect once they have passed through your system.

Furthermore, shrooms aren’t physically addictive. So, your body won’t start forming habits or reliance.

Can Drug Tests Detect Magic Mushroom Use?

Psilocybin has a very low potential for substance abuse. Therefore, it’s not often included in drug testing.

It’s certainly possible to drug test for psilocybin — it’s just not common.

Drug tests are typically checking for substances that are considered addictive or harmful. These include cocaine, opiates, phencyclidine (PCP), and amphetamines.

A drug test is described in terms of its “panels”. The number of panels refers to the number of drugs being tested for.

Standard drug tests range from four-panel to twelve-panel. None of these standard tests normally check for psilocybin.

For more information on different levels of standard drug testing, read more here.

Even when psilocybin tests are performed, they aren’t very sensitive. That’s because psilocybin isn’t easily detected.

Here’s how long shrooms will last in different parts of your system:

  • Urine – up to 24 hours

  • Blood – less than 24 hours

  • Hair – up to 90 days

These time frames are fast in comparison to some other substances. Cannabis, for example, can be detected in urine up to 30 days after use.

Psilocybin is metabolized quickly. This means that your body “takes care” of it efficiently without leaving any traces.

The highest form of detection would be a hair follicle test. This could identify psilocybin up to 90 days after use. However, performing this sort of drug test for magic mushrooms is very rare.

Employers and other drug testing parties simply aren’t often motivated to test for magic mushrooms.

Here’s the bottom line when it comes to drug tests: shrooms are not an addictive drug, so they’re rarely tested for. They have very low substance abuse potential and growing social acceptance. So, drug testing is a minimal concern with psilocybin use.

Psilocybin in Urine Tests

When it comes to shrooms, the effects may only last for 24 hours. But according to research, metabolites from psilocybin can remain in your system for up to a whopping 15 days! Though this isn’t something you worry about as long as conventional drug tests are concerned, magic mushrooms usually don’t appear on routine screens.

Of course, if you find yourself needing one soon and worried about the possible detection of psilocybin, then best consult with a healthcare provider or someone familiarised with such information!

Remember, though, that while these entheogens offer incredible therapeutic benefits when used correctly -misuse is always very dangerous, so be sure not to take any risks and practice caution before partaking in anything psychedelically related.

How to Prepare for a Urine Test after Taking Magic Mushrooms

  • Contact the testing facility or your healthcare provider: Inform the testing facility or healthcare provider that you just consumed psilocybin mushrooms so they can recognize the substance and take the proper precautions to guarantee accurate testing and result interpretation.

  • Drink plenty of water: You must drink a lot of water to remove the remaining psilocybin in your body, as it can flush out the remaining psilocybin during your pee.

  • Avoid substances that could trigger a false positive: Avoid taking a substance when your drug test is near, as it can trigger or can QDcreate a false positive on the result

  • Follow your healthcare provider’s instructions: Pay close attention if your healthcare practitioner has given you particular instructions for getting ready for the test. If not, do as directed. This can entail staying away from specific foods, medicines, or exercise for some time.

  • Stay calm: While feeling anxious or nervous about the test is natural, try to stay calm and relaxed. Stress and anxiety can increase the concentration of psilocybin metabolites in your urine, potentially affecting the results.


Factors that Affect the Duration and Potency of Psilocybin in the Body

Psilocybin is a powerful psychedelic, naturally occurring in certain fungi. A range of variables can dramatically shift the potency and duration of its effects – dosage, body weight, and regularity of use all play an important role, as does the method or route through which it’s ingested and the environmental atmosphere where one partakes. Carefully considering these details, equally intense trips yet controlled may be enjoyed!

Dosage: Regarding your psychedelic journey, the amount of psilocybin you ingest shapes its intensity and length. As dosages rise, so does the potential for longer-lasting effects – but remember that potency can also vary between different strains! Those looking to maximize their trip time should explore mushroom varieties with greater concentrations of psilocybin.

Body weight: A person’s body weight can influence their psilocybin experience – the more you weigh, the higher dose of ‘shrooms may be necessary to achieve a similar level of effects as someone lighter.

Tolerance: Psilocybin use can escalate, as higher doses may be needed over time for the same effects. This growing tolerance could reduce the length of desired trips and experiences.

Route of administration: The method of consumption can have a huge influence on the potency and duration of psilocybin. While capsules or edibles may lead to an extended, more subtle onset experience, smoking or intravenous injection will produce quicker effects that pack quite a punch!

Setting: The place you choose to trip on psilocybin can significantly influence how intensely it affects your experience. Opting for a tranquil and familiar atmosphere could make the journey more pleasurable, while seeking out unfamiliar or tense settings may amplify both its intensity and length.

Getting Started With Psilocybin Dosing

The ingestion of psilocybin-containing mushrooms warrants caution regarding its extended presence in the human system. Factors like the administered dosage, individual metabolism, and testing method employed may determine the duration of detection, which could span multiple days. The compound can remain detectable in blood or saliva for about 24 hours, while in urine, it could last for over a week.

Furthermore, it’s imperative to be aware of the potential adverse outcomes associated with psilocybin abuse and its concomitant use with other substances. Such unwarranted conduct could exacerbate the risks of drug dependence and other detrimental health outcomes. Therefore, the responsible utilization of psilocybin under the auspices of healthcare professionals is crucial.

If you have an upcoming drug test, it’s essential to disclose any recent psilocybin use to the testing facility or healthcare provider. This can help ensure that accurate testing is performed and any potential false positives are identified. It’s also recommended to avoid other substances that can potentially trigger a false positive, such as poppy seeds or certain medications.

Ultimately, by using psilocybin responsibly and being aware of how long do shrooms stay in your system, you can safely and effectively experience its potential benefits.
