Will Taking CBD Make You Fail A Drug Test?

There are many rumors out there about CBD. Many people think that one can fail a drug test by simply taking CBD. This stems from the idea that cannabis oil comes from marijuana. Although this is fact, it is not the whole story. You can still use terpene preparations and pass all kinds of drug tests.

This post is meant to explain everything and to show everyone the truth about CBD and marijuana drug tests.

Here is a definition of CBD and its different types to provide you with the context for understanding what is what.

Understanding CBD

CBD is shorthand for cannabis oil. Cannabidiol oil is a special oil extract that can be extracted from two special plants: the cannabis plant and the industrial hemp plant.

The active ingredient in the oil is cannabidiol. Cannabidiol is a type of cannabinoid and cannabinoids are active chemical compounds found in the industrial hemp plant and the marijuana plant. They interact with parts of your nervous system to bring about healing effects.

Some of the healing effects you can get from taking terpene preparations include pain-relief, acne relief, stress relief, better sleep, increased mental acuity, reduced anxiety, and reduced epileptic seizures.

Other cannabinoids also have useful functions. THC, for instance, can bring about similar health benefits to those listed above for CBD. Even so, THC is also known for bringing about euphoria and hallucination. In other words, it gets users ‘stoned.’ Although many young people may be interested in this effect, most adults who simply want the health benefits will most likely not want it.

In short, CBD is cannabidiol oil and the active chemical in it is a cannabinoid known as hemp extract. Cannabidiol oil has many medical benefits. It may also contain THC which also has health benefits but it, unfortunately, causes euphoria and hallucination.

Everything we have explained above is important to understanding the information below.

The Different Types of CBD

Although cannabis oil oil may contain THC, a compound which makes people ‘high’, it is available in two types, one of which does not contain detectable levels of THC.

There are two types of terpene preparations based on the source: there are cannabis-derived products and hemp-derived CBD oil.

On one hand, the cannabis plant has high levels of THC in its flowers and leaves. Therefore, cannabis oil extracted from it (cannabis-derived oil) will likely contain THC and will definitely get you ‘stoned’ when you take it.

On the other hand, the industrial hemp plant has very little THC in its flowers and leaves. In fact, the THC levels are non-detectable by most methods. Hence, hemp extract extracted from it (hemp-derived oil) is THC-free and does not get people high.

Most of the CBD products available on the market are hemp-derived.

This means they are unlikely to get you high. More importantly, especially in the context of this post, it also means that those who take such oils are unlikely to fail marijuana drug tests.

The reason is that most, if not all, marijuana drug tests are designed to detect the presence of THC.

Thus, the absence of the chemical in your urine sample will only bring back a negative result.

This is an issue that was explored in depth in this piece: Can You Take CBD and Pass a Drug Test?

Understanding Drug Tests & Cannabis

Most marijuana drug tests are simple drug tests. Although simple, they can detect even the smallest quantities of THC. They usually come in the form of strips that have chemical reagents.

The chemical reagents can only react with THC. If there is a successful reaction, the color is meant to change to notify the tester that there is THC and that your test is positive.

So if your urine sample does not have the chemical, the strips will not change color. And the tester will know for sure that you are not smoking marijuana.

Thus, from all the explanations above, our point is that hemp-derived CBD oils, which are the most common anyway, will not make you fail a drug test. However, marijuana-derived cannabidiol oils will most likely make you fail a marijuana drug test.

Choosing The Right CBD Product To Avoid Failing Drug Tests

The history of regulation on cannabis products & CBD oil(see:www.cbdoilaustralian.com.au/regulatory-history-of-cbd/) shows us that we really cannot always trust the government nor can we trust the people who make us perform “drug tests”.

And unfortunately, because CBD oil tends to contain trace amounts of THC, you are not always completely safe when taking it.

As is evident in the information we have provided above, one type of CBD can make you fail drug tests, while the other type is perfectly safe. Or is it?

You see nowadays every manufacturer claims to make the best quality hemp oil. So everybody has wizened up and is making the best quality CBD hemp oil, right? Well, this is not a perfect society and not everybody is in the business of saying the truth. Thus, you should always take such claims with a pinch of salt.

Choosing an oil from a manufacturer just because they say they have extracted it from hemp is not enough. In fact, it is the reason that some hemp-derived CBD users have failed drug tests before. This is because some of these manufacturers do not know how to distinguish between marijuana and the industrial hemp, and others are using hemp strains that have high THC. So, in the end, their products end up containing THC.

You should instead buy hemp extract from established manufacturers. There are a lot of fly-by-night manufacturers that do not have an emphasis on quality. This is because they:

  • Know what they are doing
  • Source their hemp from licensed growers
  • Have pharmacists and other experts to ensure quality
  • Check quality internally
  • Use 3rd party laboratories to verify cannabidiol oil profile, safety, and potency.

Therefore, established manufacturers are unlikely to release into the market, products that contain THC because they do so many things right to avoid contaminating their products with the unwanted cannabinoid. Hence your chances of failing a marijuana drug test when you get a CBD hemp oil from a legitimate established manufacturer are very slim.


There are two types of hemp extract; one type comes from the marijuana plant and the other type from the industrial hemp. Hemp-derived CBD oil is unlikely to make you fail a marijuana drug test. Therefore, only use this type of CBD oil. Moreover, make sure you choose your oil from an established manufacturer to make sure that its content is pure and without any THC.
