Will CBD Oil Result in a Positive Drug Test?

Cannabidiol or CBD has so many uses and more people believe in its potential. However, some are still hesitant about it, mainly because of the source.

What makes others raise their eyebrows is because CBD comes from the Cannabis Sativa family of plants. It only means that it includes marijuana, a potent plant considered an illegal substance in most parts of the world.

Though CBD does not have psychoactive properties, some people think that it might show up in a drug test. But would it?

This article aims to help you understand how CBD may or may not show up on your next drug test.

Would CBD Show Up on Your Drug Test?

The general answer to that is NO. But some CBD products online actually contains tetrahydrocannabinol or THC.

What does THC have to do with it? Well, THC is the main cannabinoid of marijuana. This compound gives the euphoric effect since it binds with our CB1 receptor.

According to the Farm Bill 2018, the allowed amount of THC in any CBD products is 0-0.3%. CBD, combined with too much THC, would definitely show a positive drug test result.

CBD Legalities and Your Company Regulations

CBD is legal in all 50 states in the USA unlike marijuana, which is only allowed in nine states. If you got caught with CBD, the federal law could not send you to jail.

Even with the Farm Bill, each state also has its own mandates to follow. Some jurisdictions have specific rules about CBD use, while others do not.

States such as New York, Texas, Illinois, Oklahoma, Utah, Maryland, and Alaska have specific laws regarding the use of CBD. Others like Hawaii, District of Columbia, Montana, and Kansas exempted CBD in their definition of marijuana.

Now, some jurisdictions do not have clear mandates. Florida, Mississippi, New Jersey, Idaho, Massachusetts, and Washington, among others, do not have specific rules about CBD but have exemptions.

Meanwhile, California, Ohio, Nevada, Arizona, Michigan, Alabama, and Wyoming are some of the jurisdictions that have no rules about CBD use. However, their authorities still confiscate store-sold CBD products even with the Farm Bill.

The case would be different globally. Canada, Australia, Germany, Poland, Thailand, and Greece are some of the countries, which legalized medical cannabis.

On the other hand, these countries consider cannabis-derived products illegal: the Philippines, Saudi Arabia, Singapore, Vietnam, Egypt, and Afghanistan.

But of course, the situation in the workplace is entirely different. Before signing any contract at work, read the fine prints carefully.

Some companies are particular when it comes to their substance abuse clause. You can check if the contract includes CBD use.

Types of CBD Products

You have to know the different kinds of CBD products available in the market. This way, you know if you are at risk of getting more THC than the allowed serving.

CBD Isolates

CBD isolates are, as how they are, purely extracted CBD. It is also known as the extract from the extract because the initial extract takes all the cannabinoids. The second extract is the separation of CBD from the other compounds.

According to the National Institutes of Health or NIH, purified CBD or CBD isolate may actually help in the treatment of epilepsy. But the user may need to take more servings, compared with CBD plus other cannabinoids.

Another fact is that most CBD isolates come from hemp plants, so they don’t really contain THC. They are available in powder and oil bases.

Broad-Spectrum CBD

If the label says the CBD product is broad spectrum, it means that it contains CBD, terpenes, and other cannabinoids but THC. Broad-spectrum CBD products are usually oil-based.

This type of CBD can be produced in two ways. The first one is getting the CBD isolate first then adding the important cannabinoids.

The other way is getting a full-spectrum CBD and extracting the THC out of it. Either way, the main goal is to get all the important compounds that must go with CBD except for THC.

Full-Spectrum CBD

This type of CBD contains everything – CBD, THC, terpenes, flavonoids – all the stuff you can get from the whole plant. Most CBD products under this category are from marijuana plant species.

Consequently, the challenge is knowing how much THC there is in a product. Some manufacturers do not disclose this information. They also do not include the source in the labels.

Among the three, full-spectrum CBD is available in various forms. You can buy products such as tinctures, edibles, creams, serums, and oils.

Detecting the amount of THC in Your Body

Mayo Clinic explained in 2017 that drug tests following federal mandates do not actually restrict THC per se. It means that you may still have THC in your system but it is not enough to trigger a positive result.

If you use CBD products with THC and you ended up with a negative result, it is possible that the THC amount is low.

Drugs can be detected through various methods, such as:

Blood testing

This procedure is rarely used for federal workplace drug testing. THC only stays for five hours in the bloodstream and tidbits of THC for a week.

However, testing for driving under the influence (DUI) requires blood samplings. If one shows a concentration of even just 1 ng/ml of THC, he can face jail time.

Take the state of Illinois as an example. In the past, they had zero tolerance when it comes to THC for DUI. Over the years and the current changes in the federal law, the state allows 5 nanograms or less of THC.

In some states, they do not tolerate even a single bit of it. If the authorities found even minimal traces of THC, you can say hello to a cold prison cell.

Saliva testing

The NIH suggests at least 4 ng/ml of THC limit when detecting it through the saliva. However, the standard is yet to be established.

When taken orally, THC stays for about three days in the system. It’s longer for those who use CBD with THC heavily. Most workplaces do not require this kind of testing but it may be an option should suspicion arise.

Hair testing

In the United States, hair testing is not a common method. However, in other countries like South Korea, it is a usual practice.

Though the country allows medical marijuana, South Korea is still very strict when it is for recreation. Take note that marijuana has been a part of Korean farming for thousands of years.

Some Korean celebrities tested positive with THC through hair samplings. Metabolites from THC can stay up to about three months.

Urine sampling

Urinalysis is the most common drug test companies require their applicants. It is also the best way to check the amount of CBD plus THC in the system.

At least 50 ng/ml of THC should get detected in the urine to have a positive result. Depending on how frequent you use it, THC may stay detected up to more than two weeks. It may stay over a month if you are a heavy user.

How to Avoid Getting Positive Results in Drug Tests

It is quite tricky to identify which CBD products in the market are actually “safe.”  Here are some things you may want to check before buying products or having drug tests:

1. Don’t take CBD products when the drug test schedule is near.

If you are a little panicky, stop using CBD products weeks before the drug test. It may sound on point but it may be a challenge to some.

Now, if you think that you are most likely to get a series of drug tests all your life, you may have to consider if CBD products are really for you.

2. Research while you search.

Getting recommendations from other users is a good thing. However, it is better that you do your own research in searching for the right CBD product.

Evaluate the authenticity of the manufacturer’s claims. If a company claims health-related results, it’s okay for you to doubt the product.

3. Read the label carefully.

Check the type of CBD. Read the other ingredients and their percentages or amount. Yes, check how much THC is in it.

Some manufacturers include the source, so that’s another factor to consider. Some people want to use hemp-based products, while others stick with cannabis.

Consequently, the product must show how much CBD you get per dosage. The ideal is getting CBD products with low doses.


In general, CBD does not show in any drug test, especially when you use the right products. However, you have to understand that CBD still needs firm regulation.

If you use pure CBD, there is nothing to worry about. You just need to be extra careful when you are using products laced with other cannabinoids, especially THC.

Scientific studies are far from conclusion. Amendment to laws is a possibility to keep up with the ever-changing world.

CBD restriction is almost a thing of the past. All we need to do now is to wait for another breakthrough, and that may include more lenient testing.
