Hair drug tests do not detect mushrooms. Learn how hair follicle testing works. Call (877) 731-6362 for details. --- Do mushrooms show up in a hair test? Standard hair drug tests do not detect mushrooms or their metabolites. Hair follicle testing focuses on common drugs like cannabis, cocaine, opioids, and amphetamines. For specific concerns about mushrooms, contact AMH Nationwide. Call (877) 731-6362. OVERVIEW ## Do mushrooms show up in a hair test? Mushrooms, specifically psilocybin-containing mushrooms, do not show up in a standard hair drug test. Hair follicle drug tests typically screen for substances such as THC, cocaine, opiates, amphetamines, and PCP. These tests analyze hair samples to detect drug metabolites incorporated into the hair shaft. Psilocybin and its metabolites are chemically different and not included in routine hair drug test panels. Common drugs detected: THC (Marijuana), Cocaine, Opiates, Amphetamines, PCP Mushroom compounds: Psilocybin and psilocin are not tested in standard panels Hair testing method: Detects drug metabolites deposited in hair after use If mushrooms are a concern for testing, specialized laboratory tests would be required. AMH Nationwide does not offer routine hair drug tests that detect mushrooms. Contact us to discuss testing options. TESTING DETAILS ## How does a hair drug test detect substances? Hair drug tests detect drug metabolites that enter the hair follicle from the bloodstream after drug use. Hair samples, usually 1.5 inches long, represent approximately 90 days of drug history. The laboratory analyzes the hair for specific metabolites using immunoassay screening followed by confirmatory testing with GC-MS or LC-MS/MS. Testing focuses on a defined panel of drugs regulated by [SAMHSA](https://www.samhsa.gov/workplace/drug-testing) and other agencies. Sample length: Typically 1.5 inches of hair [Detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/): Up to 90 days of drug use Testing process: Initial immunoassay screen, confirmatory GC-MS or LC-MS/MS Reviewed by certified Medical Review Officer (MRO) Because psilocybin is chemically distinct and not part of standard drug panels, it is not detected by these methods. MUSHROOMS & HAIR TESTS ## Why don’t mushrooms show up on hair follicle drug tests? Psilocybin mushrooms contain psilocybin and psilocin, which metabolize rapidly and do not accumulate in hair in detectable amounts. Standard hair drug tests do not include these compounds in their screening panels. Additionally, no federally certified testing protocols currently exist for psilocybin detection in hair samples, so laboratories do not test for them routinely. Psilocybin metabolizes quickly and leaves no stable hair metabolites No approved testing protocols for psilocybin in hair samples Standard panels focus on legally regulated substances If mushroom detection is required, specialized testing must be requested and is not part of routine hair drug testing. WHO ORDERS TESTS ## Who typically requires hair drug testing and what substances are tested? Employers, legal entities, [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/) officers, and treatment centers commonly order hair drug tests to detect commonly abused substances over a 90-day period. These tests are used for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/), random screening, post-incident, or court-ordered testing. The substances tested include cannabis, cocaine, opiates, amphetamines, PCP, and sometimes expanded panels including benzodiazepines or synthetic opioids. Employers for workplace drug screening Courts and probation departments for compliance monitoring Treatment programs for substance use monitoring Standard panels exclude psilocybin mushrooms AMH Nationwide directs test requesters to collection sites nationwide.

AMH Nationwide routes hair drug test collections through five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. We provide the lab order and direct requesters to a nearby collection site. There is no online ordering available. After collection, the sample undergoes screening and confirmatory testing. Every non-negative result is reviewed by a certified Medical Review Officer (MRO). Collection sites nationwide Labs: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, ExperTox No online test ordering; call to initiate MRO review of all non-negative results Call (877) 731-6362 to arrange hair drug testing or for more information. DOT & SAFETY-SENSITIVE TESTING ## Does DOT hair drug testing detect mushrooms? DOT-regulated safety-sensitive drug testing follows strict federally certified [urine](https://amhnationwide.com/urine-drug-testing/) testing protocols under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Hair testing is not approved for DOT drug testing purposes. Since psilocybin mushrooms are not included in standard drug panels, they are not detected in DOT urine tests or hair tests. Hair tests are used only for non-DOT roles and do not screen for mushrooms. DOT testing requires urine samples under 49 CFR Part 40 Hair testing is not accepted for DOT testing Mushrooms are not detected in DOT-approved drug tests Contact AMH Nationwide for DOT urine testing or non-DOT hair drug testing at (877) 731-6362. AMH Reviewed & Maintained By AMH Nationwide Customer Service AMH Nationwide is BBB A+ accredited and routes every order through Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox, all of which use multiple lab certification agencies and standards such as SAMHSA-aligned laboratory protocols, the ANSI National Accreditation Board for forensic testing and calibration, the College of American Pathologists (CAP), and Clinical Laboratory Improvement Amendments (CLIA). Every non-negative screen is reviewed by a certified Medical Review Officer as part of standard processing before a result is released, and chain-of-custody documentation is maintained on every collection.

Specialized tests for psilocybin in hair exist but are not part of routine drug panels and are rarely used in employment or legal testing. Hair drug tests detect drug use up to approximately 90 days prior, depending on hair length and growth rate. No, passive exposure to mushrooms does not result in detectable levels in hair drug tests because psilocybin is not tested. Neither hair nor urine drug tests detect mushrooms in standard panels. Both require specialized tests for psilocybin detection. To arrange hair drug testing, call AMH Nationwide at (877) 731-6362. We will direct you to a collection site and manage lab processing.
