In recent years, the use of psychedelic mushrooms—commonly known as “shrooms”—has become more popular both recreationally and therapeutically. This rise in usage has sparked many questions about drug testing, especially for those concerned about employment or legal consequences. One of the most common concerns is: Will shrooms show up on a urine test?
This article dives deep into what shrooms are, how they affect your body, the science behind drug testing, and whether psilocybin—the active ingredient in shrooms—can be detected in urine tests.

What Are Shrooms?
Shrooms, or psychedelic mushrooms, contain psychoactive compounds primarily psilocybin and psilocin. When ingested, psilocybin is converted into psilocin, which interacts with serotonin receptors in the brain, causing altered perceptions, hallucinations, and changes in mood and cognition.
People have used shrooms for centuries in spiritual and religious rituals, but today they are gaining attention for their potential in mental health treatment, such as for depression and PTSD.
Understanding Drug Testing: How Do Urine Tests Work?
Urine drug tests are among the most common forms of drug screening used by employers, law enforcement, and rehabilitation programs. These tests are designed to detect metabolites—byproducts your body produces after metabolizing drugs.
Most standard urine tests focus on detecting common drugs like:
- Marijuana (THC)
- Cocaine
- Opiates
- Amphetamines
- PCP
However, tests for less common substances like psilocybin are not typically included in standard drug panels.
Will Shrooms Show Up On A Urine Test?
Standard Urine Drug Tests
Standard urine drug tests do NOT screen for psilocybin or psilocin. This means if you consume shrooms, a regular drug test likely won’t detect them. Employers or organizations using routine 5-panel or 10-panel drug tests won’t find traces of shrooms.
Specialized Psilocybin Tests
While psilocybin is not part of routine testing, specialized or forensic drug tests can detect psilocybin and psilocin if specifically ordered. These tests use advanced techniques like gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-mass spectrometry (LC-MS), which can identify even trace amounts of psilocybin metabolites.
However, such tests are expensive, not common, and usually reserved for legal or medical investigations rather than workplace screening.
How Long Does Psilocybin Stay In Your System?
Understanding the detection window is crucial for knowing if shrooms can be detected in a urine test.
- Psilocybin and psilocin are rapidly metabolized.
- They are typically eliminated from the bloodstream and urine within 24 hours after ingestion.
- The metabolites do not accumulate in fat tissues like THC, so they do not linger in the system.
Because of this quick metabolism and excretion, even specialized urine tests may only detect psilocybin within a very short window after use.
Why Don’t Standard Urine Tests Detect Shrooms?
Most urine drug tests are designed to detect substances that are commonly abused and have a high prevalence, such as opioids or cocaine. Psilocybin use is still relatively rare and not included in the standard panel because:
- It’s less commonly abused in large populations.
- Detection requires sophisticated testing equipment and methods.
- Psilocybin breaks down quickly and leaves few metabolites in urine.
- There’s limited regulatory demand for its routine testing.
What About Other Drug Tests? Can Shrooms Be Detected Elsewhere?
While urine is the most common testing method, there are other ways to test for drugs:
Blood Tests
Psilocybin can be detected in blood, but only for a very short period—usually up to 6 hours after consumption.
Hair Tests
Hair follicle testing can detect drug use over a longer period (weeks to months), but psilocybin is rarely tested in hair due to its chemical properties and the rarity of such tests.
Saliva Tests
Saliva tests for psilocybin are not commonly available or used.
Factors Affecting Detection
Several factors can influence whether psilocybin can be detected:
- Dosage: Larger doses may produce detectable metabolites for slightly longer.
- Frequency of Use: Frequent use may increase detection chances, but psilocybin does not accumulate like some drugs.
- Metabolism: Individual metabolism speed affects how quickly the drug leaves the system.
- Type of Test Used: Only specialized tests can detect psilocybin.
- Time Since Last Use: Detection is only possible within a short window after ingestion.
Risks And Considerations
Workplace Drug Testing
Since psilocybin is not typically included in routine drug testing, recreational users may not worry about testing positive. However, laws and policies vary, and some employers may require more comprehensive testing or have zero-tolerance policies.
Legal Implications
Psychedelic mushrooms remain illegal in many places. Testing positive in a legal context can have serious consequences, especially in criminal cases where specialized tests might be ordered.
Medical and Therapeutic Settings
If undergoing clinical trials or therapy involving psilocybin, disclosure is necessary, and specific tests may be used to monitor drug levels.
Conclusion
- Standard urine drug tests will not detect psilocybin or psilocin.
- Specialized testing can detect shrooms, but only within about 24 hours after ingestion.
- Psilocybin is rapidly metabolized and cleared from the body.
- Detection depends on test type, timing, dosage, and individual metabolism.
If you’re concerned about drug testing related to shrooms, understanding the type of test and detection windows is crucial.

FAQs
What is psilocybin and how does it affect the body?
Psilocybin is the active psychedelic compound found in magic mushrooms (shrooms). Once ingested, it converts into psilocin, which affects serotonin receptors in the brain, leading to hallucinations, altered perception, and mood changes. Its effects typically last 4 to 6 hours.
How long after eating shrooms can psilocybin be detected in urine?
Psilocybin and its metabolites are generally detectable in urine for only about 24 hours after ingestion. After that, the compounds are usually cleared from the system.
Are there any common drug tests that include psilocybin detection?
No, standard drug tests like 5-panel or 10-panel tests do not include psilocybin. Only specialized forensic tests can detect psilocybin and psilocin.
Can shrooms cause a false positive on a drug test?
Shrooms are unlikely to cause a false positive for other drugs in standard urine tests. Psilocybin is chemically distinct from other common drugs tested.
If I’m using shrooms for therapeutic reasons, should I be worried about drug testing?
If you’re participating in a therapy program or clinical trial using psilocybin, disclose your use to healthcare providers. For employment or legal tests, it depends on the test type, but routine urine tests usually won’t detect shrooms.
