On the positive side, he noted, immunoassays are only screening tests. They would be followed up by “confirmatory testing” that does distinguish THC from other compounds. But you could still have a problem if your cannabis product was contaminated with THC, Fitzgerald said.
She and her colleagues at the University of Utah Health Sciences Center in Salt Lake City spiked three batches of urine samples with CBD, CBN and two other cannabis compounds — cannabichromene and cannabigerol.
If you think CBD products are suddenly everywhere, you’re right: There has been an explosion since last year, when Congress lifted a decades-old ban on growing hemp.
According to Robert Fitzgerald, a professor at the University of California, San Diego’s Center for Advanced Laboratory Medicine, “It would depend on the purity of the product.”
The simplest course is to refrain for a while, according to Kroner. But she also advised being up front about your CBD or CBN use — or any supplement use, for that matter — so that your test results can be interpreted in that light.
Why did only one test pick up CBN? The tests are known immunoassays — which means they use antibodies to detect drugs. Kroner explained that there are slight differences in the antibodies that test manufacturers use — so it’s possible to get different results.
A 2017 study found that about seven out of 10 CBD products did not contain the amount of cannabidiol stated on the label. And about one in five contained THC.
Medterra Ultra Broad Spectrum CBD tincture is a fantastic way to get the benefits of a full plant hemp extract with no THC. This formula contains organic CBD plus additional plant compounds like CBG, CBC, CBN, CBDV, and terpenes. All Medterra products are made with Kentucky grown hemp that is free from pesticides and certified by the U.S. Hemp Authority.
We recommend broad spectrum oils whenever possible. That’s because the addition of secondary cannabinoids, terpenes, and flavonoids can interact with one another to produce a more potent result. However, if you want to make absolutely certain that the product does not contain even trace amounts of THC, go with a CBD isolate.

To choose the best CBD oils, you want to look for products that have been independently tested by a third-party lab. This is crucial to make sure that the CBD oil is both free from toxins or harmful compounds like heavy metals and to check that it contains the correct concentration of CBD. When selecting a THC-free CBD tincture, this is especially important for determining that the product does not contain significant levels of THC. Look for brands that include a QR code on the label or links on their site so you can see the test results for yourself.
