A common question among both casual users and those facing drug testing is: how long do shrooms stay in your system? Psilocybin, the primary psychoactive compound in magic mushrooms, is rapidly metabolized in the body, but its byproducts can remain detectable for a limited time depending on several key factors.
Understanding the detection window of psilocybin, how it’s processed by the body, and whether it appears on standard drug tests is essential for anyone considering responsible psychedelic use or preparing for a screening.
This guide breaks down how long shrooms typically stay in your bloodstream, urine, saliva, and hair. It also covers the factors that affect individual clearance rates and what you can do to manage timelines effectively.
What Factors Affect How Long Do Shrooms Stay in Your System?
The answer to how long do shrooms stay in your system isn’t universal, it depends on several personal and physiological variables. These factors not only influence how quickly psilocybin is metabolized and excreted but also affect whether it shows up on a drug test.
By understanding these variables, users can form realistic expectations around psilocybin detection windows and make informed choices regarding timing and safety.
Metabolic Rate and Body Composition
Your metabolism plays a central role in how quickly your body processes and eliminates psilocybin. Individuals with a faster metabolic rate tend to break down and excrete compounds more quickly, which may shorten detection time.
Body composition also matters. While psilocybin itself isn’t fat-soluble, some residual compounds may linger slightly longer in individuals with higher body fat percentages.
The liver metabolizes psilocybin into psilocin, which is then excreted through urine, making hydration and liver function critical for clearance speed.
Dosage and Frequency of Use
The more psilocybin you consume, the longer it will likely take your body to eliminate it. A single microdose may be cleared within a day, while a full recreational dose (or repeated use over several days) can extend the detectability window.
Frequent users may build up residual metabolites, slightly extending how long shrooms remain in their system. However, psilocybin clears relatively quickly compared to other hallucinogens like LSD or THC.
If you’re planning regular use, review how often you can take shrooms safely to understand risk factors and proper timing.
Type of Drug Test and Detection Methods
Different drug tests vary in sensitivity and detection windows:
- Urine tests are the most common and can detect psilocybin metabolites for 1 to 3 days after use, depending on dosage and metabolism.
- Blood tests detect psilocin for a shorter duration, typically only up to 24 hours after ingestion.
- Hair follicle tests, although rare for psilocybin, could potentially detect use for up to 90 days, but they are not typically used in standard drug panels.
Understanding these differences helps clarify how long shrooms stay in your system and show up on drug tests, especially in legal or employment-related scenarios.
How Long Do Shrooms Typically Remain Detectable in the Body?
The duration that psilocybin remains detectable depends on both the type of drug test and individual biological factors. While psilocybin is metabolized relatively quickly, certain tests can still identify its presence within specific windows.
Understanding these timelines is key for anyone concerned about screening or simply monitoring their body’s elimination process.
Here’s how long shrooms typically stay in your system across common testing methods:
- Urine Tests: Psilocybin and its primary metabolite, psilocin, are usually detectable in urine for up to 24 hours after ingestion. In cases of high doses or slower metabolism, this window may extend to 48 hours.
- Blood Tests: These are less commonly used due to their short detection window. Psilocin is typically only detectable in blood for about 6 to 12 hours after consumption, making it a narrow window for identification.
- Hair Follicle Tests: Though rarely administered for psilocybin, hair tests can potentially detect psilocybin use for up to 90 days. However, this method is not standard practice and is unlikely in routine screenings.
If you’re asking how long do shrooms stay in your system and show up on drug tests, the most likely scenario involves a short detection window of 1–2 days, unless specialized testing is conducted.

Estimated Detection Times for Different Usage Patterns
| Usage Pattern | Urine Detection Window | Blood Detection Window | Hair Detection Window |
|---|---|---|---|
| Single Use | Up to 48 hours | Up to 12 hours | Up to 90 days |
| Repeated Use | Up to 3 days | Up to 12 hours | Up to 90 days |
Can Shrooms Be Detected on Common Drug Tests?
One of the most frequently asked questions is whether shrooms can show up on standard drug tests, especially in the context of employment or legal screenings. While psilocybin is a psychoactive compound, it’s not typically included in routine drug test panels, which means detection is uncommon in most standard scenarios.
However, under certain conditions, specialized tests can detect psilocybin and its metabolites, raising the importance of knowing which testing methods apply.
Are there any drug tests specifically for magic mushrooms?
Yes, but they are not widely used. Specialized testing methods such as:
- Enzyme Immunoassays (EIA)
- Gas Chromatography-Mass Spectrometry (GC-MS)
can accurately detect psilocybin or psilocin in blood, urine, or hair. These tests are typically reserved for forensic investigations, clinical studies, or legal proceedings, not routine employment screenings.
Due to the cost and specificity required, they are rarely applied in standard workplace environments.
Will a standard drug test show if I used shrooms?
In most cases, no. Standard drug panels, including 5-panel and 10-panel tests used by employers, focus on substances like:
- THC (cannabis)
- Cocaine
- Opiates
- Amphetamines
- PCP
Psilocybin is not included in these common panels, meaning typical mushroom use won’t trigger a positive result. However, in contexts like military service, probation monitoring, or specialized toxicology tests, psilocybin detection may be requested.
So while how long shrooms stay in your system matters biologically, their likelihood of being tested for remains low, unless a specific test is ordered.
Is There a Reliable Way to Avoid Detection of Shrooms in Drug Tests?
For those concerned about how long shrooms stay in your system and whether they show up on drug tests, it’s natural to wonder if there are reliable ways to speed up elimination or avoid detection.
However, the truth is that no proven method exists to reliably “flush” psilocybin from the body before a test.
Since psilocybin is metabolized fairly quickly and not typically screened for in standard drug tests, the best approach is still time and abstinence. Attempting to manipulate test results using unproven detox strategies may not only be ineffective, but also unsafe.
Detox Products and Their Effectiveness
A variety of detox teas, supplements, and cleansing kits are marketed to users hoping to eliminate substances like psilocybin more rapidly.
Unfortunately, there’s no scientific evidence supporting the idea that these products significantly reduce detection time for magic mushrooms.
The most effective and reliable “detox” is your body’s natural metabolic process, which typically clears psilocybin and its metabolites within 24 to 48 hours after a single dose.
Staying hydrated, eating well, and resting may support general metabolism, but won’t dramatically alter test outcomes.

Conclusion
Understanding how long shrooms stay in your system is essential for making informed, responsible decisions, especially if you’re facing potential drug testing.
While psilocybin is metabolized quickly, its detectability depends on several key factors, including dosage, frequency of use, metabolic rate, and the type of drug test administered.
- Urine tests typically detect psilocybin metabolites for up to 24–48 hours.
- Blood tests have a shorter window, usually 6–12 hours.
- Hair follicle tests, though rare for psilocybin, may identify use up to 90 days post-consumption.
While most standard drug panels do not test for shrooms, specialized screenings may. Detox products offer no guaranteed protection, making abstinence and time the only reliable methods to ensure clearance.
