For instance, say that someone who had direct contact with marijuana then touched your hair. You could feasibly receive a false positive on a drug screening that tests your hair.
These compounds were derived from a full-spectrum product rather than a CBD isolate product alone. This is one reason that full-spectrum products (those containing THC) are popular.
In theory, getting a false positive on a drug test from CBD oil should be relatively impossible from pure CBD oil containing less than 0.3% THC. However, because CBD oil is not well regulated, there is no guarantee that a product contains pure CBD oil, or that its concentration is safe or effective.
This article explains why a positive drug test can happen with CBD use, which types of CBD are most likely to trigger one, and what you can do to avoid it.
How to Avoid a Positive CBD Drug Test
CBD oil is usually marketed as THC-free, but that's not always the case. Full-spectrum CBD oils contain other cannabinoids, which may include THC. Isolate products may be contaminated with THC, as well.
However, the distinction between full-spectrum oils and isolates makes all the difference if you are being tested for drug use.
Cannabis is the umbrella term describing hemp and marijuana plants—two different varieties of the Cannabis genus. Both marijuana and hemp can be described as cannabis, but they are two different plants.
Cross-Contamination of THC
There are several common reasons a person fails a CBD drug test.
Drug tests look for tetrahydrocannabinol (THC), which is the element in marijuana that causes a high. CBD oils can have trace amounts of THC even if they're labeled “THC-free.” The FDA does not regulate these products, and mislabeling is common.
Again, CBD won’t show on a standard drug test because it’s not a concern for employers or law enforcement. However, choosing the wrong CBD oil, such as full-spectrum CBD oil, could show positive for THC.
Check the label to see if the CBD product is full-spectrum, broad-spectrum, or pure CBD isolate. If it mentions “CBD” but does not mention if it’s full-spectrum or broad-spectrum, then it’s most likely a CBD isolate.
The best way to make sure that a CBD product doesn’t contain THC is to inform yourself. Checking for THC is easy if you know where to look. Once you know what makes a good CBD product, buying your first one will be a breeze.
A reputable CBD company offers some key signs of quality. They don’t all have to be there, but enough to create a well-rounded, potent, safe, THC-free CBD oil.

Depending on several factors, CBD could remain inside you for days or weeks.
Hemp farmers have no choice but to destroy any crops exceeding 0.3% THC. If producers don’t consistently test their plants and products, you could receive something with substantially more THC.
While CBD itself doesn’t trigger a drug screen, the CBD oil you use might do so. In this case, the issue isn’t CBD, but if THC is present or not. Some hemp CBD extracts, such as full-spectrum CBD oil, contain up to 0.3% THC that a drug test may show positive for THC.
Check the Label
Since CBD is federally legal and doesn’t impair or artificially improve athletic performance, there is no reason organizations need to test for CBD. It would be a waste of time and money.
A CBD oil with small amounts of THC may not be much on its own. But if you consistently consume a full-spectrum product, your body could build up THC and test positive down the road.
If you take a dietary supplement or edible that contains CBD, the effects won’t be felt immediately. Your metabolism and diet can influence how soon you feel the effects. However, symptoms are often felt within an hour of digesting it.
If you smoke dried flower CBD or use a vape cartridge, the CBD enters your bloodstream within seconds. Therefore, brain effects associated with CBD occur the quickest in this manner.
How Long Does CBD Stay In Lab Tests?
Although blood tests are not nearly as common as urine tests for screening for CBD and cannabinoids, they can be used to detect THC metabolites. The reason they’re not the preferred method of drug screening is because of how quickly THC is eliminated from your bloodstream.
