At the other end, you could theoretically take CBD hemp oil for months, at low amounts (50 mg/day), and never fail a urine screen for THC-COOH. It’s not clear how much CBD hemp oil is needed—or for how long—to end up with more than 50 ng/ml of THC-COOH in your urine. But certainly, if you’re taking large amounts of CBD, depending on the source, you could test positive for THC.

A pure “isolate” of just the CBD molecule, which is commercially available, should not contain any THC. However, these isolates are extracted from hemp oil, and are of varying quality. By law, federally legal hemp oil can have up to 0.3% THC in it. Sometimes that number is higher, because of variations in test results.

Here’s how drug tests work. Employers collect and send off samples—largely urine—to drug testing companies who run them through a machine that can measure trace chemicals in the liquid. Technicians look for evidence of a byproduct of THC, the main active cannabinoid in cannabis — not CBD. (More rarely, employers may test saliva, hair, or blood from their employees. We’ll get to that in a minute.)

How long does CBD stay in your system?

“It’s caveat emptor,” said Barry Sample, Ph.D., senior director of science and technology for employer solutions at the nation’s biggest drug testing company, Quest Diagnostics. “The real issue is, how do you trust the labeling?”

You won’t get drug tested for CBD—you’ll be drug tested for THC. If you’re concerned for any reason, you may consider following the detoxification guidelines for THC, including discontinuing use, dieting, exercise, and staying hydrated to get trace THC out of your system.

Multiple human trials of large doses of oral CBD have never resulted in the detection of THC in the blood plasma of test subjects—so if it’s happening outside of a lab beaker, no one’s proved it. Dr. Ethan Russo debunked the stomach acid theory in Trends in Pharmacological Sciences forum article Cannabidiol Claims and Misconceptions.

Furthermore, if you consume enough CBD—on the order of 1,000 milligrams a day of CBD—just the residual THC could put your test results in the danger zone. This is a big deal because a failed drug test can result in the denial of loss of both job and income, and can also lead individuals to lose access to important resources like education and welfare benefits, child custody, and prescriptions for pain medication.

The likely answer to this question is NO. Understand that most drug tests will not test for CBD since it is legal at the federal level in the United States. Remember, however, that CBD is just one of many cannabinoids present in cannabis, but so is THC, which is still a controlled substance. Now, most companies don’t care if you have CBD in your system, because it doesn’t create any impairment or high sensation. So, when most companies administer work drug tests, they are likely looking for THC, CBD’s cousin. Why? THC is the compound present in marijuana that is responsible for making you feel high. Companies test for the presence of THC because it impairs their employees’ performance and could even result in injuries at the workplace.

If you are not well informed, you may even end up shaving your head, thinking this will help you manipulate the results. Don’t even think about it: if you choose to shave a week or month before your test, the technician will just use hair from another part of your body. Besides, if you shave your hair too soon, your employer may suspect you of drug use.

Reasons You Could Fail a Drug Test

For these reasons, CBD newcomers are often concerned about consuming this cannabis extract. Now, we can help alleviate your fears but, to do so, we have to help you understand how CBD works, so you can make an informed choice about using this cannabinoid.

If you use CBD products and you need to take a drug test soon, you might be wondering how long it takes for the trace amounts of THC to leave your body. It is essential to know that the duration of time the THC lasts in your body depends on so many things, including the amount you consumed, your body’s metabolism, your diet, and the strain used. If you are a rare user, it could take 21 days or more for the THC to leave your body. If you are a weekly user, you might have to wait for a month or more for the THC to be eliminated. Therefore, the frequency of your CBD use will significantly affect how long the THC will take to leave your body. If you have a pending drug test, you need to consider the above factors.

You may feel confident about testing negative on your drug test after using CBD, only to discover that you’ve failed. And, some people test positive for THC when using a full-spectrum CBD product such as CBD oil. Below are the reasons why.

It is noted that CBD extracts from the marijuana plant that contains high levels of THC are illegal to consume or use.

There is a scenario where false-positive results could happen, but they are also very rare and would require a number of set of circumstances to occur. Additionally, it is important to consider that the result is not a false positive more so a detection of low levels of the drug in the system.

Could a false positive result happen?

To avoid this unlikely scenario, labs should use different testing methodologies from GC-MS, or they should avoid the agent trifluoroacetic anhydride (TFAA). Fortunately, more advanced drug testing facilities have moved away from GC-MS and are using RP-HPLC, a faster and more reliable test. The High-Performance Liquid Chromatography linked to a tandem mass spectrometry (LC/MS/MS) offers more detail into the different cannabinoids and delivers results in as little as 10 minutes. GC-MS is still widely used for testing broadly about which drugs have been consumed, but it can lack certain details, as is proven in this example.

11-nor-9-carboxy-THC (THC-COOH) is a true metabolite of THC. When THC is abused, THC-COOH will be produced within the body, as the main metabolite (breakdown product) of THC. Therefore, the presence of THC-COOH can only be due to the consumption of THC and not from the consumption of CBD.

If hair testing was not conducted initially or it was not tested for THC-COOH then request DNA Legal to perform a hair test that looks for THC-COOH. This will confirm if the person was only positive for CBD or has consumed THC as well.
