Drug tests identify tetrahydrocannabinol (THC) or its metabolites. Although these tests do not detect CBD, some CBD products contain low amounts of THC that could theoretically cause a person to fail a drug test. In most cases, CBD oil is very unlikely to show up in a drug test. Most employment drug tests specifically look for the presence of THC or THC metabolites. Most employers follow the guidelines set by the Substance Abuse and Mental Health Services (SAMHSA), which include screening for THC but not CBD. Mouth swabs don't test for CBD - again, they test for THC," Sample said.
So no, CBD will not show up on a standard workplace drug-testing mouth swab. However, THC will, so avoid large amounts of CBD with THC levels. Stop us if you've heard this, but workplace hair follicle tests generally don't look for CBD, they look for the old familiar THC-COOH. So no, CBD will not show up in a standard workplace drug test of a hair follicle. Any CBD you take that has THC levels could leave THC by-products in a hair follicle, where they have the potential to linger for a while. Hair follicles can contain a record of months of drug use, depending on the length of the hair.
Note that most substance screening tests performed are for the compound THC. Most workplace drug tests are designed to detect THC and other illegal drugs, so the odds of taking CBD products and passing a drug test are in your favour. You won't fail a drug test for CBD, but you could fail a drug test for any THC residue in that CBD product. Tens of thousands of false positives could stem from this error annually, according to estimates by journalist Amanda Chicago-Lewis, but at least there is some recourse: CBD users have successfully challenged a failed drug test for THC if the lab used this specific method, which can result in a false report of CBD as THC. If your employer tests for THC, you should avoid any CBD products that are labelled as full-spectrum, as they contain a trace amount of THC that may cause you to fail the drug test. Although it is unlikely that you will fail a THC drug test because of CBD, it is always good to be informed about the cannabinoids present in your favourite CBD products.
But failing a THC drug test for taking CBD depends on the source of the CBD, the amount you took, the duration, your metabolism and other factors such as hydration levels. If a CBD user tests positive for THC, either the test is inaccurate or, more likely, the non-THC product contained some THC. In contrast, workers fail workplace drug tests because of the main active ingredient in marijuana, THC, which can exist in low amounts in some CBD products and then persist in the human body for weeks. If you are one of the many CBD oil users who are worried about failing a THC drug test, this post has the information you need to know. Most of these drug tests look for THC in addition to other illegal drugs, but this does not include CBD oil. With this in mind, you might think you have to avoid full-spectrum CBD products containing THC if your workplace conducts drug screens.
The good news is that there is a new type of drug test on the market that tests the ratio of CBD to THC in your system.
