Do shrooms show up on a drug test?
If you’re working under DOT regulations or for a zero-tolerance employer, this question is more relevant than ever in 2025. With psilocybin (the active compound in “shrooms”) gaining attention in both therapy and recreation, many employees wonder: Can I get caught during a drug test?
Let’s break it down.
What Are Shrooms?
Shrooms are psychedelic mushrooms containing psilocybin, a mind-altering substance. While a few U.S. states have decriminalized psilocybin, it remains federally illegal and classified as a Schedule I drug.
DOT-covered workers (CDL drivers, airline staff, etc.) are still subject to federal laws, regardless of state-level legalization.
Do Shrooms Show Up on a Drug Test in 2025?
Here’s the short answer:
👉 Standard DOT drug tests do not test for shrooms, but specialized tests can.
DOT’s Standard 5-Panel Test Screens for:
- Marijuana (THC) 
- Cocaine 
- Opiates (heroin, codeine, morphine) 
- Amphetamines (including meth) 
- PCP 
So, psilocybin (shrooms) is not part of the default DOT panel in 2025.
BUT employers can request extended panels that include psilocybin—especially if:
- You self-disclose psychedelic use 
- You show signs of impairment 
- It’s a high-security or zero-tolerance job 
Detection Windows for Psilocybin
| Test Type | Detection Window | 
|---|---|
| Urine (basic) | 1–3 days (rarely detects shrooms) | 
| Urine (advanced) | Up to 7 days | 
| Blood | Up to 24 hours | 
| Hair Follicle | Up to 90 days (advanced labs) | 
Pro Tip: Just because most employers don’t test for it doesn’t mean they won’t.
Will Shrooms Affect Your Job or CDL?
Yes—even without a positive test.
Under DOT policy, you can still face:
- Suspension or termination 
- Mandatory SAP Evaluation 
- Return-to-Duty process 
If your employer suspects impairment or has a zero-tolerance policy, shroom use could result in loss of safety clearance.
What Happens If You Admit to Shroom Use?
You may be required to:
- Undergo a DOT-qualified SAP Evaluation 
- Complete education or treatment 
- Pass a Return-to-Duty test

Legal ≠ Allowed at Work
Even if your state has decriminalized shrooms:
- DOT regulations still apply 
- Federal employers and contractors follow federal law 
- You can be removed from duty even without a failed test 
Key Takeaways
- Do shrooms show up on a drug test? Not always—but they can. 
- Standard DOT drug panels in 2025 don’t test for psilocybin. 
- Employers can use expanded panels or act on behavioral suspicions. 
- Use under federal employment may lead to disciplinary action or mandatory SAP treatment.
