How Long Do Shrooms Stay in Your System? Drug Test Detection Guide

Key Takeaways¶

• Shrooms contain psilocybin, a psychedelic compound that turns into psilocin in the body.
• Shrooms may stay in your system for a few hours to several days.
• Most standard drug tests don't detect psilocybin, but specialized tests can.
• Detection depends on the test type: urine, blood, saliva, or hair.

Introduction¶

Shrooms, or magic mushrooms, are a type of psychedelic drug used for their mind-altering effects. One common question: How long do shrooms stay in your system?

Understanding how long psilocybin and psilocin remain detectable can help you make safer, more informed decisions—especially if you’re facing a drug test or noticing lingering mental health effects.

What Are Shrooms and How Do They Affect You?¶

Shrooms contain psilocybin, a naturally occurring hallucinogen. Once consumed, your body converts psilocybin into psilocin, which interacts with serotonin receptors in your brain.

• Onset of effects: typically 30–60 minutes after use
• Peak effects: around 1–3 hours
• Total trip duration: about 4–6 hours for most people

Common effects include changes in perception, mood, and thought patterns. Some people experience euphoria and spiritual insights, while others may have anxiety, paranoia, or a “bad trip.”

How Long Do Shrooms Stay in Your System?¶

While the noticeable effects of shrooms usually wear off within several hours, traces of psilocin can remain in your body for hours to several days. How long they stay detectable depends on:

• Body weight and composition
• Metabolism and liver function
• Dose taken (how many grams or how potent the mushrooms are)
• Frequency of use (one-time vs. repeated use)
• Type of drug test being used

In general, psilocybin and psilocin are processed and eliminated relatively quickly compared to many other drugs. However, certain tests—especially hair tests—can detect use long after the effects have worn off.

Drug Test Detection Times¶

Different drug tests have different detection windows. Most routine workplace tests do not look for psilocybin or psilocin, but specialized tests can.

Urine Test¶

Urine tests are the most common type of drug test. Standard urine panels usually do not include psilocybin, but a specialized test can be ordered.

• Typical detection window: about 1 to 3 days after use
• Heavy or repeated use: may be detectable for up to a week

Because psilocin is water-soluble and cleared fairly quickly, the window for detection in urine is relatively short compared to substances like cannabis.

Blood Test¶

Blood tests are less common for detecting shrooms and are usually used in emergency or medical settings.

• Typical detection window: up to 12 hours after use

Blood tests are best for showing recent use, not past use. After about half a day, psilocin levels usually drop below detectable limits.

Saliva Test¶

Saliva tests for shrooms are rare and not typically used in standard drug screening.

• Typical detection window: up to 24 hours after use

Because psilocybin and psilocin are rapidly metabolized, saliva tests are only useful for very recent use.

Hair Test¶

Hair tests have the longest detection window, but hair testing for shrooms is extremely rare and usually only done in specialized or forensic settings.

• Typical detection window: up to 90 days after use

Drugs and their metabolites can become trapped in the hair shaft as it grows, which is why hair tests can show a longer history of use. However, due to cost and limited need, hair testing for psilocybin is not commonly performed.

Do Standard Drug Tests Check for Shrooms?¶

In most cases, no. Standard workplace drug tests—such as 5-panel or 10-panel screens—typically focus on:

• Marijuana (THC)
• Cocaine
• Opiates
• Amphetamines
• PCP

Expanded panels may include benzodiazepines, barbiturates, methadone, or other substances, but psilocybin and psilocin are usually not included.

A lab can test specifically for psilocybin or psilocin, but this requires a special request and is not part of routine employment or probation testing.

Lingering Effects and Mental Health Risks¶

Even after shrooms have left your body, mental and emotional effects can linger. Some people experience:

• Difficulty concentrating or focusing
• Mood swings or emotional sensitivity
• Flashbacks or brief returns of perceptual changes
• Increased anxiety
• Worsening depression

In some cases, people may develop ongoing problems such as:

• Persistent anxiety or panic
• Depressive episodes after the trip
• Hallucinogen Persisting Perception Disorder (HPPD) – rare, but involves recurring visual disturbances

If you notice that your mood, thinking, or perception hasn’t returned to normal after using shrooms, professional support can help you stabilize, process the experience, and address any underlying mental health conditions.

When to Seek Help¶

You may want to reach out for help if:

• You’re using shrooms to cope with stress, trauma, or mental health symptoms
• You feel out of control with your use or keep taking more than you planned
• You’re experiencing ongoing anxiety, depression, or disturbing thoughts after a trip
• You’ve had a frightening or traumatic psychedelic experience

Specialized treatment can help you:

• Understand your relationship with substances
• Manage cravings or urges to use
• Treat co-occurring conditions like anxiety, PTSD, or depression
• Learn healthier coping skills and relapse-prevention strategies
