CBD is not detected by drug tests 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. 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. CBD will not show up on a drug test because drug tests do not detect it. However, CBD products may contain THC, so you may fail a drug test after taking CBD products.
If you take CBD oil, you should plan accordingly if your work or activities require you to undergo drug testing. The production of CBD products remains unregulated. The Food and Drug Administration does not verify THC concentrations in CBD products. As a result, products labelled as "THC-free" or "low THC" may still contain more than the legal concentration limit of 0.
This means that regardless of the type of CBD oil you buy, you run the risk of failing a DOT drug test. You won't fail a drug test for CBD, but you could fail a drug test for any THC residue in that CBD product. Workers who use 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 because of 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.
Very small amounts of THC present in the material from which CBD is extracted can be introduced into CBD oil in quantities high enough to give a positive drug test result. 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, how much you took, how long you took it, 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. The most common reason for a failed CBD drug test is that a person is using a CBD oil product that contains THC. However, with the rise of CBD comes the concern of failing a drug test due to the detection of CBD oil.
In theory, getting a false positive drug test for CBD oil should be relatively impossible from pure CBD oil containing less than THC.
