But what if your CBD oil contains small traces of THC? Many top CBD manufacturers have products with no presence of THC. Although hemp-derived CBD products are legally allowed to contain a maximum of 0.3% THC, some prospective consumers may still be reluctant to try CBD that contains even a small amount of THC. Thankfully, there are ways to create hemp-derived CBD products without any hint of the intoxicating cannabis compound.
There are also different types of drug tests that can be used, all of which present different detection thresholds. For instance, a hair test is made to detect habitual substance use, so it will probably not raise any red flags even if you are consuming CBD oil that has low levels of THC.
Should you worry about CBD oil showing up on a drug test?
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.
While there are certain CBD products, such as distillate and crystalline, that contain zero THC, the fears of inexperienced consumers may still persist. Like most things in the constantly evolving cannabis space, there are a number of factors to consider.
But how can you tell how much THC, if any, might reside inside your CBD oil? Can you really trust everything the label on the side of the bottle? The safest bet is to look for well-known CBD products that are independently tested.
If you use a lot of full-spectrum CBD products that contain up to 0.3% THC, it’s certainly possible that this THC might show up in a hair follicle test. One thing follicle tests are great about, though, is determining exact concentrations of substances. So, it should be readily apparent that the amount of THC you consumed was too small to have been from a cannabis product, proving you used hemp instead.
Just as with other CBD products, the potential to fail a drug test after using a hemp topical certainly exists. To understand how topical and oral CBD might affect drug testing differently, we need to look at the differences between the oral and transdermal CBD administration routes.
As a DOT employee, a positive THC result may still result in termination even if you claim you “only used a CBD product.” Proceed with caution.
5. Will CBD make me fail a hair drug test?
A hair drug test, also known as a follicle drug test , provides detailed data on the substances you’ve used that goes back much further than urine testing (urinalysis).

Out of all the different types of CBD, full-spectrum CBD is the most likely to cause a false positive on a drug test for THC. That’s because full-spectrum hemp products might contain up to 0.3% THC, which is allowed by the 2018 Farm Bill .
As you can imagine, consuming enough products containing 0.3% THC can make you fail a drug test. Even though it’s in concentrations so small that a single CBD flower session could never make you high, those tiny amounts of THC can accumulate in your fatty tissues over time to make it seem like you’ve used more THC than you have.

Seen as the ideal combination of CBD isolate and full spectrum, broad spectrum contains all of the additional cannabinoids found in plants from the cannabis family, but with the THC completely removed.
However, with the growth in popularity, comes a growth in confusing messaging leading to misinformation. This misinformation is particularly problematic when people’s jobs are at risk.
