Learn what hair drug testing detects and how labs process samples. Call (877) 731-6362 for details. --- Does CBD come out in hair follicle drug test? Hair follicle drug tests screen for THC metabolites, not CBD itself. Since CBD products typically contain minimal THC, most hair tests do not detect CBD use. Testing is conducted through national labs and reviewed by certified Medical Review Officers. Call (877) 731-6362 for more information. Overview ## What does a hair follicle drug test detect? A hair follicle drug test detects the presence of drug metabolites deposited in hair shafts after drug use. The test primarily targets THC-COOH, the metabolite of THC found in marijuana, along with other substances such as cocaine, opiates, amphetamines, and PCP. CBD itself is not included in the standard drug panels used by national labs because it is non-intoxicating and not classified as a controlled substance. Drugs detected: THC metabolites, cocaine, opiates, amphetamines, PCP CBD is not a target analyte in hair follicle drug testing Hair tests detect drug use over a 90-day window typically AMH Nationwide routes hair drug tests 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. Results are reviewed by certified Medical Review Officers to ensure accuracy and compliance. CBD and Hair Testing ## Does CBD come out in hair follicle drug test? CBD itself does not come out in hair follicle drug tests because these tests do not screen for cannabidiol. However, some CBD products contain trace amounts of THC, which can metabolize and be detected in hair. The likelihood of THC detection depends on the amount and frequency of THC exposure through the CBD product. Most standard hair tests cannot differentiate between THC from cannabis use versus trace THC in CBD products. CBD is not directly tested in hair follicle drug tests Trace THC in some CBD products may result in positive THC metabolite detection Detection depends on product THC content and usage frequency If a hair follicle drug test is required for DOT-regulated safety-sensitive positions, only federally certified [urine](https://amhnationwide.com/urine-drug-testing/) testing is accepted; hair tests are used for non-DOT roles. For any concerns about CBD use and hair testing, contact AMH Nationwide at (877) 731-6362. [Detection Window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) ## What is the detection window for hair follicle drug tests? Hair follicle drug testing typically detects drug metabolites deposited in hair over approximately 90 days. Hair grows about half an inch per month, and the standard 1.5-inch hair sample represents about three months of drug exposure. This detection window applies to THC metabolites and other substances tested. CBD use is not detected because it is not screened for in hair tests. Detection window: up to 90 days after drug use Sample length standard: 1.5 inches of hair Detection reflects past drug exposure, not recent or one-time use Because hair testing reflects long-term use, occasional or one-time exposure to THC through CBD products is less likely to appear unless the THC content is significant or use is frequent. Testing Process ## How does AMH Nationwide process hair follicle drug tests? AMH Nationwide coordinates hair follicle drug testing by providing lab orders and directing individuals to one of over 20,000 nationwide collection sites. Samples are collected following strict chain-of-custody procedures and sent to one of five national labs for analysis. Every non-negative result is reviewed by a certified Medical Review Officer to confirm findings and interpret results according to regulatory guidelines. Collection sites nationwide for convenience Samples analyzed by Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, ExperTox Certified Medical Review Officer reviews all non-negative results No online ordering; lab orders provided by AMH Nationwide Contact AMH Nationwide at (877) 731-6362 to schedule a hair follicle drug test or for further questions about the testing process. ## Need a Hair Follicle Drug Test?

CBD use alone does not cause false positives because hair follicle drug tests do not target CBD. However, CBD products with low levels of THC could produce positive results for THC metabolites if used frequently or in large amounts. Labs use sensitive and specific testing methods to differentiate substances, and all positive results undergo review by a Medical Review Officer to rule out false positives or alternative explanations. CBD alone does not trigger positive hair test results Trace THC in some CBD products can cause positive THC metabolite detection Certified Medical Review Officer evaluates all positive results for accuracy For accurate interpretation of hair follicle drug test results related to CBD use, contact AMH Nationwide at (877) 731-6362. Regulations ## Are hair follicle drug tests accepted for DOT-regulated testing? Hair follicle drug tests are not accepted for Department of Transportation (DOT) regulated safety-sensitive testing. DOT requires federally certified urine drug testing under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Hair testing is primarily used for non-DOT employment, court, [probation](https://amhnationwide.com/hair-follicle-drug-test-probation/), or personal testing purposes. CBD use and hair test results should be discussed with the test administrator to understand testing requirements. DOT requires urine testing, not hair testing Hair follicle tests used for non-DOT roles CBD is not tested in DOT urine tests either Call (877) 731-6362 to learn more about DOT testing protocols and hair follicle drug testing options through AMH Nationwide. 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](https://www.samhsa.gov/workplace/drug-testing)-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.

However, if the product contains THC, especially in higher amounts, it may result in a positive test for THC metabolites. THC from contaminated CBD products can appear in hair follicle tests within days, but hair testing reflects drug use over up to 90 days. Occasional CBD use with low THC is unlikely to produce a positive result. Hair follicle drug tests do not test for CBD and cannot differentiate the source of THC metabolites. The test only detects THC metabolites regardless of origin. Hair testing is more effective at detecting long-term THC use but does not detect CBD. Urine testing also does not screen for CBD but is required for DOT-regulated tests. If you test positive, contact the Medical Review Officer who reviews all non-negative results. They can evaluate your medical history and product use to interpret the result accurately. Passive exposure to CBD will not cause a positive hair follicle drug test. Only THC metabolites are detected, and trace environmental exposure is unlikely to register in hair tests.
