CBD will not show up in a drug test because drug tests do not detect it. However, CBD products can contain THC, so you can fail a drug test after taking CBD products. Drug tests do not detect CBD because it does not cause intoxicating effects and is not an illegal controlled substance. However, people who use CBD can fail a drug test.
Products containing CBD may be contaminated with THC or have incorrect labelling. Very small amounts of THC present in the material from which CBD is extracted can enter CBD oil in high enough quantities to give a positive result in a drug test. This scenario may be more likely to occur when CBD oil is purchased from cannabis dispensaries in places where cannabis is legal, rather than from an online retailer. 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. If you are in a profession where a failed drug test could ruin your career, I strongly advise you to make sure your CBD oil comes from a reputable company. You won't fail a drug test for CBD, but you could fail a drug test for any THC residue in that CBD product.
CBD by itself will not cause you to fail a drug test, but THC will, and many CBD oils have some amount of THC in them. Simply put, if a CBD company gets its oil from hemp, and that hemp is grown according to the letter of the law, it would take a LOT of CBD oil to fail a drug test. Workers who consume a lot of CBD (cannabidiol) for pain, anxiety, insomnia, or a host of other symptoms, can accidentally (and unfairly) fail drug tests for cannabis in certain cases, the media and experts report. Instead, workers fail workplace drug tests for marijuana's main active ingredient, THC, which can exist in low amounts in some CBD products and then persist in the human body for weeks.
In the most common workplace drug test - a urine test - employers do not look for CBD, because CBD has never been found to affect judgement or motor skills. Tens of thousands of false positives could result from this error each year, 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. Although hemp-derived CBD products are available in states where recreational cannabis is not legal, some people may worry that their CBD oil consumption will show up on a drug test. But failing a THC drug test for taking CBD depends on the source of your CBD, the amount you took, the duration, your metabolism, and other factors such as hydration levels.
To obtain a CBD oil drug test, an employer or entity would have to pay a testing company an additional fee to change their testing regimen to include CBD.
