Shrooms in Your System: Psilocybin Drug Test Guide
How Long Do Shrooms Stay in Your System? (2025 Guide)
Whether you're planning your next trip, microdosing daily, or sweating a drug test—knowing how long magic mushrooms stay in your system is smart. Psilocybin may be natural, but it still shows up on specialized drug panels, and your body's metabolism doesn't clear everything instantly. This deep-dive breaks it all down: how psilocybin is processed, what affects detection time, which drug tests look for it, and how long it really takes to flush out.t.
🧪 Quick Answer: Detection Times
| Test Type | Detection Time |
|---|---|
| Urine | 1–3 days (rarely tested) |
| Blood | Up to 24 hours |
| Saliva | Not detectable |
| Hair | Up to 90 days (extremely rare for psilocybin) |
Most users eliminate psilocybin in under 48 hours—but it depends on dose, metabolism, and usage habits.
🧬 How Psilocybin Is Metabolized
After ingestion, psilocybin converts into psilocin, the active compound that causes the trip. Psilocin binds to serotonin receptors, then is broken down by the liver and excreted via urine and feces.
Half-life of psilocin: ~2–3 hours. Most of it clears from blood in under 24 hours.
🧠 What Affects How Long It Stays in You?
- Dose: Bigger dose = longer trace time
- Frequency: Regular users clear slower
- Metabolism: Faster metabolism = quicker clearance
- Body fat: More fat = slower breakdown
- Hydration: Helps speed natural flushing
🔍 Does Psilocybin Show Up on Drug Tests?
Most standard drug tests do NOT test for psilocybin. Your typical 5-panel or 10-panel test (used by employers) checks for:
- THC (Cannabis)
- Cocaine
- Opiates
- Amphetamines
- PCP
Psilocybin is **not** on the list. Specialized labs can test for it, but it’s rare—think military, rehab, or high-level security jobs.
🧪 Test Types Breakdown
1. Urine Tests
Most common. Psilocin shows up for **1–3 days** post-trip. Longer for heavy users.
2. Blood Tests
Detects active psilocin for **12–24 hours**. Only used in high-urgency scenarios (DUI, hospital intake).
3. Saliva Tests
Psilocybin and psilocin don't stay in your mouth long. **Not detectable** via saliva.
4. Hair Tests
Can detect drug use for up to **90 days**, but labs rarely look for psilocybin. Only high-end tests would catch it.
⚡ Can You Flush Psilocybin Faster?
Yes, but only naturally. There’s no miracle detox. Here’s what helps:
- 💧 Stay hydrated (2–3L per day)
- 🚶♂️ Light cardio, sweat it out
- 🥦 Eat liver-supporting foods (turmeric, beets, leafy greens)
- 🛌 Sleep and rest—your body detoxes during rest
Don’t bother with: cranberry juice, activated charcoal, or “detox drinks.” These are scams or ineffective.
📈 Real World Clearance Timelines
- 1 gram dose (1-time user): ~24–36 hrs to fully clear
- 3.5g “eighth” trip: ~2–3 days
- Daily microdoser: Might have traces in urine for 3–5 days post-last dose
🧠 Microdosing vs. Full Dose Detection
Microdosing involves sub-perceptual doses (50–200mg) every few days. These clear fast, but consistent use **can stack up** slightly over time.
Still, microdosing doesn’t usually trigger detection on normal panels unless you're in a clinical or research test.
📛 Legal Note (Canada)
Psilocybin is currently a controlled substance in Canada. However, personal use enforcement is very low, and testing is rare outside military, court-ordered, or licensed therapy settings.
✅ Final Takeaway
For 99% of people, psilocybin clears from your body in under **48 hours** and won’t show up on a drug test. If you're being tested for psilocybin specifically, that’s a rare case and you’ll usually know in advance.
Stay hydrated, take breaks from frequent use, and don’t stress over myths. Your body handles mushrooms pretty efficiently.
