Does CBD Show Up On a Drug Test?

Does CBD Show Up On a Drug Test?

CBD products are widely used and touted for their potential relaxation and wellness benefits. But if you’re a user of CBD, you might wonder, does CBD show up on a drug test? How long does it take for CBD to work?

While CBD itself won’t show up on a drug test, CBD products containing traces of THC might. Luckily, there are ways you can tell which category your favorite products (such as CBD oils or CBD topicals) fall under. 

This guide outlines everything you need to know about CBD and drug tests, including how much THC it takes to produce a positive test and how to find a THC-free CBD product for your needs. 

Why Won’t CBD Show Up On a Drug Test?

CBD or cannabidiol is a derivative of the hemp plant and is the second most active ingredient in marijuana. While the hemp and marijuana plants are both the same species, the hemp plant is categorized as any cannabis plant that contains 0.3% or less THC (the compound that produces a high), while a marijuana plant contains more than 0.3% THC.

In the same line, CBD products in the United States cannot contain more than 0.3% THC per federal limit.

Since most drug tests screen for THC, there is little chance that consuming CBD will result in a positive drug test. 

According to the guidelines set by the Department of Health and Human Services, THC must be present in a concentration of at least 50 nanograms per milliliter, which would mean you would need to intake ⅓ of a marijuana joint-worth of THC to fail the drug test. Anything less than that isn’t considered a positive test. 

These guidelines apply to urinalysis tests which are the most commonly used workplace drug screening tests. So the next time you’re deciding how to wind down after work, consider using CBD products that comply with federal regulations.

What Could Cause CBD Products to Show Up On a Drug Test?

In situations where CBD products produce a positive drug test result, THC is present. This happens because not all CBD is derived from hemp. Harvesting and refining techniques can also impact what compounds are found in your CBD.

While CBD won’t cause you to fail a drug test, using CBD products comes with risks. There are several scenarios that could lead to a positive test, such as:

  • CBD products containing THC – Even products labeled isolate CBD can contain traces of THC if you purchase them from an untrustworthy source. Both broad and full-spectrum CBD typically contain small amounts of THC. If you’ve been using one of these types of CBD, you might fail a drug test.
  • Inaccurately labeled CBD products – CBD products aren’t regulated by the FDA. Thus, the label doesn’t always match what’s actually in the product. If you purchase a poor-quality CBD product, you’re rolling the dice with the contents.
  • Cross-contamination of CBD products – If you purchase CBD products from a  dispensary that also sells cannabis, there’s a small risk of cross-contamination. This would result in a small amount of THC ending up in your CBD products.

How to Choose the Right CBD Product

When you’re navigating the world of CBD products, it can be tricky to choose the right ones for your needs. However, if a drug screening test is in your future, you want to be certain that you’re getting onlyCBD without any additional compounds.

Let’s look at the three different types of CBD that are on the market.

#1 Full-Spectrum CBD

As the name implies, full-spectrum CBD contains all of the compounds that naturally occur in the plant from which it’s derived. This includes the:

  • CBD
  • Flavonoids
  • Terpenes
  • Other cannabinoids (including THC)

Unlike some other types of CBD, full-spectrum extracts are taken from marijuana plants. Because it’s derived from marijuana, there will be traces of THC in the product. It’s difficult to tell exactly how much THC is in full-spectrum CBD products because it can vary widely depending on the manufacturer. 

Does CBD get you high? It’s not likely that there will be enough THC to produce the high that you get from marijuana, but there might be enough to trigger a positive drug test.

Full-spectrum CBD products are widely available. However, if you’re concerned about the amount of THC in the product interfering with an upcoming drug test, you should opt for broad-spectrum or pure CBD isolate instead.

#2 Broad-Spectrum CBD

Broad spectrum CBD is the middle ground of CBD products. It contains all of the natural compounds that full-spectrum has exceptfor the THC. You’ll most likely find broad spectrum CBD in the form of an oil. It’s also frequently used for topical body products such as:

  • Balms
  • Creams
  • Bath bombs

If THC content is a concern, seeking out a broad-spectrum product can help with that worry. However, you should always make sure you’re purchasing your CBD products from a trusted source. Product labels can be inaccurate, and you might end up with a product that has THC in it when you thought you were purchasing a broad-spectrum CBD oil.

#3 CBD Isolate

Lastly, CBD is sold in isolate form. This is a pure type of CBD that doesn’t contain any other compounds. After processing to remove any other compounds, you’re left with pure, crystalized CBD. These crystals are ground up into a powder and used in products, like:

  • Gummies
  • Oils
  • Creams
  • Capsules

The refining process for CBD isolate is more difficult, thus these products may be more expensive than full-spectrum and broad-spectrum CBD. However, CBD isolate is an excellent choice when you:

  • Need assurance that your products don’t contain any THC
  • Want to consume larger amounts of CBD
  • Prefer a product with no odor or flavor of its own
  • Have a drug test coming up and want to make sure there’s no issue

How Can You Ensure Your CBD Products Don’t Contain THC?

Ultimately you’re responsible for doing the legwork to ensure your CBD products are THC-free if you need to take a drug test or are otherwise concerned about THC content. 

Typically, there are three things to add to your THC-free checklist.

#1 Look For Label Accuracy

One of the biggest issues plaguing CBD products is inaccurate labeling. In fact, a study by Penn Medicine found that nearly 70% of CBD products sold online were mislabeled. 

Inaccurate labels mislead the user about the levels of THC in the product. They can also over and underestimate the amount of CBD present. To ensure you’re getting what the label promises, you should:

  • Carefully read the ingredients 
  • Note the listed amount of CBD the product contains
  • Check the type of CBD the product is made from

#2 Find the COA

What’s the COA, you ask? The COA, or Certificate of Analysis, is your assurance that the product has been tested by a third-party. The third-party is an outside lab without a connection to the company. 

You can usually find the COA by scanning a QR code right on the package. If you can’t find a QR code, you can check the company’s website. 

The COA should:

  • List the same ingredients as the product label
  • Match the label’s claim for the concentration of CBD in the product
  • Tell you if there’s any THC in the product
  • Be no more than 1 year old

If the product label and COA don’t match, that’s a red flag that the company might not be transparent about what ingredients are in the product. 

#3 Research the Company

Lastly, you should research the company. There are a few ways to approach this:

  • Contact them and ask questions about ingredients and manufacturing practices
  • Identify where the company sources their hemp
  • Check the FDA’s website to see if the company has received any warning letters

Ideally, the company will source its hemp from the United States, and organically grown hemp is optimal.

Types of CBD Products on the Market Today

CBD products come in many different forms. The best one for you depends on how you want to take CBD and what you want to use it for:

  • Edibles – CBD edibles are popular in gummy form. People love that they are available in many different flavors and are delicious to consume. Plus, CBD-infused gummies may help to promote your overall health and wellness.
  • Oils – CBD oils are taken sublingually or under the tongue. They come in a variety of flavors and work quickly since they’re absorbed directly into the bloodstream. Try a premium CBD oil to support mental clarity and tranquility.
  • Tablets – Tablets are another way to consume CBD. If you want to promote a positive mood or induce relaxation, CBD tablets are an excellent, easy-to-use choice.
  • Topicals – You can also use a CBD topical application like a CBD cream or balm to ease joint stiffness and muscle soreness.
