Tetrahydrocannabinol (THC) is the principal psychoactive constituent of cannabis. Although, as a cannabinoid it shares many of the same known health benefits as CBD, its high-inducing properties mean it is still classified as a Class B controlled drug in the UK, and therefore illegal to sell and to purchase.
As more studies are undertaken, and more research published, we will continue to update you with all the latest findings regarding CBD.
Why do companies drug test?
Many CBD sellers are lying to their customers when they tell them that they will definitely pass a drug screen. Full spectrum CBD oil contains trace amounts of THC so there will always be a risk (however minor) of triggering a positive. Our advice is to know what you’re vaping, and buy from reputable sources. If you want to be extra sure that your pee will be THC free, opt for a either a CBD isolate product like these, or a broad spectrum product like these.

For CBD to be legal in the UK, it needs to originate from an EU-approved industrial hemp strain. These certified strains all contain <0.2% THC. Even though these legal THC limits will have absolutely no effect on your cognitive function, or your ability to perform your job, they may still be detected during a routine drug test.
CBN, meanwhile, is far less famous than its cousin, but it is used in products marketed as sleep aids.
“Confirmatory testing should be done before any clinical decisions are made,” she said.
It all points to the importance of taking “cross-reactivity” into account when a drug screening test comes back positive, Kroner said.
What should you do if you use any of these products and have a drug test coming up?
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.
Whichever method, or methods, you choose, be sure to buy from a reputable source and check the label carefully. Since the Food and Drug Administration (FDA) hasn’t established guidelines for CBD products, it’s buyer beware. Avoid any product making health claims like that it cures or treats anything specific. Most reputable CBD producers typically include the following information on their product labels:
When consuming pure CBD, there is evidence you’ll be missing out on some health goodies conveyed by the entourage effect if you chose a full- or broad-spectrum CBD product instead. But it’s the only way to be certain there’s no THC in your CBD, and the only way to buy CBD in states with highly restrictive laws.
What drug tests look for
If you prefer CBD oil, tincture, gummies, or other ingestible forms, go with a product made from CBD isolate or crystalline CBD. These use 99% pure CBD so you don’t have to worry about THC or anything else being in there.
There is mounting evidence that hair follicle drug testing methods are not able to accurately detect marijuana. Research published in the journal Scientific Reports suggests that the presence of THC and THC metabolites can be transferred to the hair follicles of non-consumers through contact with hands, sweat, or exhaled smoke.
For example, if someone smokes a joint and exhales near someone who doesn’t consume cannabis, THC can be transferred to the non-smoker’s head or body hair. The same study found that, after giving participants 50 milligrams of THCA every day for one month, no THC was found in the hair specimen samples, but THC-COOH was still detected. As for the detection period, the hair follicle drug test timeline is much broader than with urine and blood tests, sometimes detecting the presence of THC up to 90 days after use.
