Learn how CBD is detected in hair drug tests and what employers should know. Call (877) 731-6362 for testing info. --- Does CBD show up on a hair follicle test? Hair follicle drug tests are designed to detect THC and other controlled substances, not CBD itself. However, some CBD products contain trace amounts of THC, which can be detected. AMH Nationwide processes hair tests through five national labs with certified Medical Review Officers. Call (877) 731-6362. BASICS ## Does CBD Show Up on a Hair Follicle Test? CBD, or cannabidiol, itself does not show up on a standard hair follicle drug test. These tests target THC metabolites, the psychoactive component in cannabis, rather than CBD. Hair follicle tests analyze hair samples for drug metabolites incorporated into the hair shaft from bloodstream exposure. Since CBD is non-psychoactive and chemically distinct from THC, it is not the primary target of hair testing. TEST DETAILS ## Does CBD Show Up in Hair Follicle Drug Test Results? Hair follicle tests used by employers and courts detect THC metabolites, not CBD. However, some CBD products contain trace THC levels, which can accumulate and be detected in hair samples. Detection depends on product purity, frequency of use, and dosage. Full-spectrum CBD products may contain enough THC to trigger a positive hair test, while CBD isolate products typically do not. Full-spectrum CBD: Contains trace THC, may yield positive results CBD isolate: Pure CBD, unlikely to show up on hair tests Broad-spectrum CBD: THC removed, minimal detection risk LAB PROCESS ## How Does AMH Nationwide Process Hair Follicle Drug Tests? AMH Nationwide routes hair follicle 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. Each lab follows strict protocols for sample collection and analysis. All non-negative hair test results are reviewed by certified Medical Review Officers (MROs) to ensure accuracy and proper interpretation before reporting. [DETECTION WINDOW](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) ## What Is the Detection Window for CBD or THC in Hair Follicle Tests? Hair follicle drug tests can detect THC metabolites for up to 90 days after use, depending on hair length and growth rate. CBD itself is not typically tested or detected in hair. Because THC metabolites accumulate in hair over time, occasional or one-time use of CBD products with trace THC may or may not be detected depending on timing and product potency. ## Need a Hair Follicle Drug Test?

Employers using hair follicle drug tests should be aware that CBD products, especially full-spectrum types, may contain enough THC to cause positive results. Testing focuses on THC metabolites, not CBD. It is important to communicate with testing labs and Medical Review Officers regarding potential CBD use to avoid misinterpretation of results.

They detect THC metabolites. However, some CBD products contain trace THC which may be detected. Using full-spectrum CBD products with trace THC can potentially cause a positive hair test. Pure CBD isolate products are unlikely to result in positives. THC metabolites can be detected in hair for up to 90 days. CBD itself is not detected, but THC from CBD products may show depending on use frequency and product. Hair follicle tests follow federal and industry standards but focus on THC metabolites. CBD detection is not part of standard federally regulated testing.
