Does CBD Show Up On Drug Test? A New Guide for Consuming

Cannabidiol (CBD) is one of the hundreds of compounds found in the cannabis plant. Unlike its more notorious cousin, delta-9-tetrahydrocannabinol (THC), which produces mind-altering effects when consumed, CBD is innocuous and most beneficial for a wide range of uses, including pain relief. The question is, since it is so closely related to THC, Does CBD Show Up On Drug Test?

Straight to The Point: Does CBD Show Up On Drug Test?

No, CBD shouldn’t show up on a drug test. The routine drug tests screen for the usual suspects: narcotics like opioids and methamphetamines, and THC, the psychoactive ingredient in marijuana. As someone who doesn’t use hard drugs, there’s nothing to worry about. That said, if you use CBD products from an unreliable supplier, it could contain large enough doses of THC to trigger a positive drug test result. The problem is, most people are under the impression that the CBD products they use are THC-free. In reality, no product derived from a cannabis plant, be it hemp or marijuana, is entirely devoid of the psychoactive compound. How much THC is too much?

The Relationship Between CBD and THC

CBD comes primarily from hemp plants, which have considerably lower THC content than marijuana plants. A plant variety is the greatest determiner of how much THC is contained in a CBD product. As a legal requirement, hemp products shouldn’t have more than 0.3 percent of THC content. That’s much lower than can be detected by a drug test. However, because it is so unregulated, different CBD suppliers use other crops to get the extract. CBD products with high THC content are likely sourced from marijuana plants and hybrids. To understand it, you need to know the different types of CBD spectrums.

The Three Main CBD Spectrums

Full-Spectrum CBD

A cannabis plant contains three types of compounds:
  • Cannabinoids
  • Flavonoids
  • Terpenes
Recent studies show that full-spectrum CBD oil has more potent healing properties because it contains more than just CBD extract. Full-spectrum products tend to contain CBD along with healthy portions of flavonoids, terpenes, and cannabinoids. Unfortunately, one of these cannabinoids is THC. Legally speaking, a full-spectrum product should not have more than 0.3 percent THC content allowed. But since full-spectrum CBD oil often comes from marijuana subspecies, not hemp plants, it may contain THC in varying amounts. It’s harder to know how much THC your full-spectrum CBD edibles contain when the manufacturer is not forthright with the information. They don’t often reveal the source of their full-spectrum extracts, so it’s not easy to spot a product with high THC content. And, like all other CBD products, full-spectrum CBD comes in oils, tinctures, topical creams, and even CBD gummies for anxiety and stress.

Broad-Spectrum CBD

Broad-spectrum CBD contains CBD plus terpenes, flavonoids, and other cannabinoids. The difference is that all of its THC is removed during the manufacturing process. Broad-spectrum CBD is much safer in terms of THC levels. If you enjoy the benefits of full-spectrum CBD, but would rather not risk accidental THC intoxication, broad-spectrum is the way to go.  It is less likely to contain enough THC to show up on a drug test, so it’s a safer choice. On the downside, broad-spectrum CBD is mostly available as an oil. Due to its rigorous and expensive manufacturing process, not only is it pricey, but it can also be hard to find.

CBD Isolate

Pure CBD is known as CBD isolate. It is derived from the extraction of pure CBD from a cannabis plant. Most CBD isolate products are hemp-based. Hemp has a much lower THC content than marijuana, so CBD isolates don’t typically contain THC. A perk of extracting CBD in its pure form is that it can be packaged as a crystalline powder or a small crystalline slab that can be ingested directly. Pure CBD isolate is also available in tinctures and oils.

How Long Does THC Last in the Body?

If you’re not a heavy cannabis user, any THC you unknowingly consume from a CBD product can last up to 13 days in your system. During this period, it can appear in urine and blood screenings. Only in heavy cannabis users can detect THC for up to 30 days.

Why CBD May Cause you to Fail a Drug Test

Even if you’ve not smoked, vaped, or ingested any marijuana product, a drug test can still detect traces of THC in your blood and urine if you use low-quality CBD. Here are a few ways CBD can cause you to fail a drug test.

When the Product Contains THC

It’s not uncommon for CBD products to contain more than the legally allowable amount of THC. The FDA doesn’t regulate CBD products, so there is no way to verify the manufacturer’s sources and processing methods. This is most likely if you get your CBD from an unreliable supplier.

Cross-contamination During Manufacturing, Packaging, and Reselling

Where you get your CBD products matters too, some CBD manufacturers also produce marijuana-based products, so cross-contamination is exceptionally likely, especially if they make both CBD and THC products in the same facility.

When you Buy a Mislabeled Product

The legal requirement is that no hemp-based product should have more than 0.3 percent of THC. Unfortunately, the law doesn’t regulate CBD manufacturers, so sellers may mislabel their products with misleading titles such as “THC-free” or “Pure CBD” even when the product is a low-quality, marijuana-derived iteration of CBD oil.

Exposure to Secondhand THC

Although inhaling secondhand marijuana smoke may not be enough to show traces of THC in your system, it’s not to be ruled out. Spending hours in a room with heavy marijuana users can cause enough THC inhalation to appear in drug tests for up to two weeks.

What CBD Products Should You Consider?

CBD Isolate

CBD isolates are high-quality and hemp-derived, so there’s a significantly lower risk of THC contamination. Plus, only a handful of manufacturers can afford the expensive extraction process, even though that means CBD isolates are a little more expensive.

CBD Gummies

CBD gummies for anxiety and stress often contain pure CBD extract that is unadulterated by other cannabis compounds, including THC. They’re ideal for children and adults alike as they’re easier to consume.

Broad-Spectrum CBD Oil

If you see no reason why you should miss out on the benefits of the other cannabis compounds, your best option is broad-spectrum CBD. It contains all the goodness of full-spectrum CBD except for THC, which is stripped away entirely during the manufacturing processes.


CBD should not show up on a drug test. However, many CBD manufacturers are not open about the quality of their products, which is why it’s common to find CBD products with high concentrations of THC. To avoid accidentally consuming THC before a drug test, make sure you get your CBD from a trusted supplier. Furthermore, steer clear of full-spectrum CBD, as it is more likely to contain THC, and avoid pot smokers because secondhand marijuana smoke can leave traces of THC in your system.
