Do Shrooms Show Up on a Drug Test? Explained

If you’re exploring psychedelics like mushroom gummies or chocolates, you’ve likely asked yourself: “Do shrooms show up on a drug test?” That’s one of the top questions we hear—especially from folks balancing curiosity with career obligations or legal concerns. Let’s break down what science and testing protocols actually say in 2025.

🍄 What Are Shrooms, Really?

Shrooms—aka psilocybin mushrooms—are naturally occurring fungi that contain the psychedelic compounds psilocybin and psilocin. Once consumed, psilocybin converts to psilocin, which interacts with serotonin receptors in the brain. The effects can include vivid visuals, altered thinking, and a shifted sense of time—usually lasting 4 to 6 hours.

If you’re microdosing or trying out psychedelic edibles, the effects may be milder—but the chemistry still counts.

🧪 So, Do Shrooms Show Up on a Drug Test?

Not on standard drug tests.

Most 5-panel and 10-panel tests used for employment or legal screening focus on these substances:

THC (Cannabis)
Cocaine
Opiates
Amphetamines
PCP

That means psilocybin and psilocin typically go undetected, unless a test is customized to look for them. So if you’re asking “do shrooms show up on a drug test” in a typical workplace setting, the answer is: very unlikely.

🔬 What About Specialized Drug Tests?

While rare, some advanced tests can detect psilocin. These are usually reserved for:

Law enforcement investigations
Military screenings
Drug rehab programs

Here’s how long shrooms could show up:

Urine: up to 24–48 hours
Blood: up to 15 hours
Hair: up to 90 days (but almost never used)

According to a study published in the Journal of Analytical Toxicology, detection windows for psilocin are short-lived—and most labs don’t even look for it.

⏳ How Long Do Shrooms Stay in Your System?

The body processes psilocybin quickly. You may feel the effects for several hours, but chemical traces fade fast:

Test Type	Detects Shrooms?	Window
Urine	Rare	1–2 days
Blood	Rare	< 15 hrs
Hair	Extremely Rare	~90 days
Saliva	Not Applicable	N/A

Still asking, do shrooms show up on a drug test? Unless it’s hair testing or a forensic scenario, it’s probably a no.

🍫 What If I Eat Mushroom Gummies or Chocolates?

Here’s where it gets interesting: not all mushroom edibles are psychedelic. Many gummies use adaptogenic mushrooms like lion’s mane or cordyceps, which are totally legal and test-safe.

If your treat contains real psilocybin (like some microdose formulas), a specialized test might catch it—but this is super rare.

🎯 Factors That Influence Detection

Whether or not shrooms show up can depend on:

Your metabolism
The dose and frequency
Test sensitivity
Body fat and hydration

Casual, one-time use? You’re probably fine. Chronic use or legal supervision? That’s a different story.

💡 What About False Positives?

One common myth is that eating mushrooms could cause a false positive for other substances like LSD or MDMA. According to toxicology experts, this is highly unlikely. Standard drug panels are chemically designed to identify specific metabolites—not confuse psilocybin with entirely different compounds.

If you’re using over-the-counter mushroom supplements, there’s virtually zero chance of triggering a false positive on a workplace drug test.

Still concerned? Stick to lab-tested, legal products and check the label for clarity.

🧬 Can Shroom Use Affect Other Medications or Tests?

Yes. While unlikely to show up on a standard drug screen, psilocybin may interact with certain medications, especially SSRIs or MAOIs. These interactions won’t cause you to fail a drug test, but they could impact your experience—or your health.

If you’re taking prescription meds or undergoing medical testing, talk to your doctor before using psychedelics, even in microdose form. The same goes for supplements labeled as “psychedelic” or “nootropic.”

📍 Is Psilocybin Legal in 2025?

Federally, psilocybin is still classified as a Schedule I substance. But:

Oregon allows licensed psychedelic therapy
Colorado and several U.S. cities have decriminalized use

It’s complicated—so always check your state or local laws before experimenting.

🔚 Final Thoughts

So, back to the big question: do shrooms show up on a drug test? Unless you’re being specifically screened for psychedelics, you’re in the clear. But if you’re in a sensitive legal or professional situation, it’s always wise to verify what’s in your system—and in your snacks.
