For instance, producers can isolate CBD compounds after the oil is extracted from the stalks and seeds from hemp plants. This process leads to pure CBD, effectively eliminating any THC and other plant-based constituents from the end product. Once isolated, the CBD can be mixed with liquid oils that contain fatty acids to improve absorption.

Should you worry about CBD oil showing up on a drug test?
Under the SAMHSA framework, the cutoff limit for the presence of THC is 50 nanograms per milliliter. Following these guidelines, if an extremely high dose of 2,000 milligrams of CBD oil that contains 0.3% THC was consumed, there’s a slim chance of receiving a “false positive” result on a urine screening.
Cannabidiol (CBD) has recently surged into the therapeutic spotlight for its perceived anti-inflammatory, anti-anxiety, pain-relieving, and seizure-suppressing properties. It can be found in health and wellness aisles across the world — perhaps even at your local Walgreens or CVS — and comes in many forms, some of which include CBD oil, tinctures, edibles, elixirs, and more.

It is difficult to say how much THC needs to be present to cause a positive drug test because this depends on several drug and patient-specific variables, and also the cutoff value for the test.
Despite the widespread use of urine drug tests, there appears to be some inconsistency in the interpretation of test results. Considering the significant consequences a false-positive result can have (such as loss of job or imprisonment), this is somewhat surprising. But it is also something to be aware of, because it may mean that what is considered a pass (a negative result) in some circumstances may be considered a fail (a positive result) in others.
If you want to pass a drug test, don't take CBD; or if you are taking it legally within your State's laws, then declare it (however it still may be contaminated with THC unless brought by a reputable supplier who guarantees it to be THC-free).
Broad-spectrum CBD is also less likely to be contaminated with THC. This is because all the THC is removed in broad-spectrum CBD as opposed to full-spectrum CBD which contains all of the compounds that naturally occur in the plant they were extracted from. CBD isolate is also pure CBD, and typically comes from hemp so it shouldn’t contain THC.
There are two main types of urine drug tests: screening and confirmatory tests. Immunoassay screening tests can be conducted on-site (point of care testing) or in a laboratory and allow large numbers of tests to be performed at once with relatively rapid results, providing an initial estimate of the presence or absence of drugs. There are three main types available, and all use antibodies to detect the presence of specific or classes of drug metabolites. Unfortunately, this can mean that substances with similar characteristics may be detected, resulting in false-positive results.
CBD products can still be problematic, however, when it comes to drug testing. Though drug tests screen for THC, not CBD, many CBD products contain a trace amount of THC which will be detected in your bloodstream during a drug test.
If you are concerned that THC in your CBD oil or other CBD product may show up on a drug test, you may be able to reduce the chance of that occurring, though there is no guarantee. Some of the factors that may increase the likelihood of a failed drug test are:
Factors in CBD Oil Showing on Drug Screen
Topical products that claim to contain CBD—like shampoos, cosmetics or creams—should not cause any reaction during a drug test because they do not enter the bloodstream. In the case of CBD oils, gummies, teas or transdermal patches, the situation is more complicated. In a test of 84 CBD products obtained online, 18 contained THC.
CBD has taken off as a natural remedy for a variety of ailments. CBD products like CBD oil can be made from either the hemp plant or the cannabis plant, which are closely related varieties of the same cannabis species, Cannabis sativa. CBD products contain a cannabinoid—a chemical—called cannabidiol, which does not make you high. The substance in marijuana that causes a buzz is a different cannabinoid, called THC, or tetrahydrocannabinol.
The legality of CBD products can be confusing. CBD products made from certain cannabis plant varieties are legal only in states where marijuana is legal, due to the potential THC content. CBD products made from hemp variety plants are legal throughout the United States as long as they contain less than 0.3% of THC and do not make any medical claims. (A hemp plant is defined as Cannabis sativa that contains less than 0.3% THC.)
