In a nutshell, yes, CBD can give a positive result on a drug test. Although there are certain steps you can take to ensure that the product you're buying contains as little THC as possible, there is no guarantee that the labeling is accurate due to the lack of regulation of CBD products. Hair tests are known to be able to detect drugs over an extended period of time, and they can detect THC metabolites in CBD up to three months after administration. However, hair tests are also very rare to detect THC and CBD.
Drug tests don't usually measure CBD. Most tests detect THC, the psychoactive component of marijuana. Depending on the frequency of use, THC can be detected in a test from a few days for a single use or for a month for heavy marijuana smokers on a daily basis. This is because active cannabinoids, such as CBD and THC, are highly unlikely to reach the bloodstream.
If you mention “CBD”, but don't mention whether it's full-spectrum or broad-spectrum, it's most likely a CBD isolate. When the Food and Drug Administration tested several CBD products, approximately 70% contained more or less CBD than advertised, while some did not contain CBD. Unless your workplace has a specific rule prohibiting the use of CBD products, you shouldn't be denied a job for consuming CBD. If you're worried about whether or not your CBD will show up in a drug test, look for products that contain 0.0% total THC.
The most common reason for failing a CBD test is that a person is using a CBD oil product that contains THC. It's also worth noting that since CBD products aren't regulated by the FDA, you may be taking CBD mixed with other cannabinoids, which could increase detectability. Since CBD is federally legal and doesn't artificially affect or improve sports performance, there's no reason why organizations should test for it. It is possible to find full-spectrum CBD topical products, such as Sunset Lake CBD ointment, that will not appear on drug screenings. Specifically, the use of full-spectrum CBD products that contain small amounts of THC may appear in workplace drug testing.
Some hemp CBD extracts, such as full-spectrum CBD oil, contain up to 0.3% THC, so a drug test can test positive for THC. This means that a 30 ml CBD tincture, regardless of the strength of the CBD, will contain a maximum of 0.00036 nanograms of THC. However, there are some things to keep in mind if you want to be completely sure as you begin your next round of drug testing. Cross-contamination is much more likely to occur in facilities that manufacture both CBD and THC products, including delta-8 THC and other isomers. Creating broad-spectrum CBD requires more processing and specialized equipment, making this form of CBD more expensive than the full-spectrum form of CBD.
Broad-spectrum CBD oil is a midpoint between full-spectrum isolated CBD with THC and isolated (but rather hollow) CBD without THC.
