Employment drug tests are designed to detect impairment not supplementation so most tests are not designed to detect CBD but rather to detect THC. Because there are trace amounts of THC in most hemp-derived CBD products, the regular consumption of very high doses of CBD (over 1000mg/day) may trigger a false positive result. It is, however, extremely unlikely that even high doses of CBD products would exceed allowable limits of THC per milliliter of urine. Many employers in legal areas are now looking past a THC-positive test result due to an inability for standardized tests to determine impairment and due to increasing use because of legalization. Please check your local laws for details that apply to you. Some pre-surgical medical tests will test for CBD because it interacts with anesthesia. We recommend full disclosure of our product use to your medical professionals. If trace amounts of THC are a concern for you we recommend using our CBD isolate tincture which has 0% THC.
