will cbd oil cause me to fail a drug test

Some sources report that in rare cases, false positive test results have come from CBD oil that breaks down into very small amounts of THC in the stomach. Other studies, however, have refuted this.  

Most CBD products are made from hemp, not marijuana.

In fact, one study discovered that almost 70 percent of the CBD products sold online were not labeled properly, “causing potential serious harm to its consumers.” The reason for this widespread mislabeling is that CBD products are not strictly regulated by the FDA.

How to Avoid a Positive CBD Drug Test

Cannabis is the umbrella term describing hemp and marijuana plants—two different varieties of the cannabis genus. Both marijuana and hemp can be described as cannabis plants; however, it is important to note that they are still two separate plants.

Inadvertent exposure to marijuana (via secondhand smoke) is unlikely to be enough for a person to get a positive drug test result, but it is possible. Being in a room with heavy pot smokers for several hours may cause the inhalation of enough THC containing smoke to result in a positive test.  

There are several common reasons a person fails a CBD drug test.

The most common reason for a failed CBD drug test is that a person is using a CBD oil product that contains THC. Sometimes, this may be because a person purchases a low-quality product that does contain a small amount of THC—most manufacturers will claim their products do not contain THC, but this is not always the case.

“Confirmatory testing should be done before any clinical decisions are made,” she said.

Given that context, it’s important to understand how the compounds interact with drug screening tests, said Grace Kroner, lead researcher on the new study.

A 2017 study found that about seven out of 10 CBD products did not contain the amount of cannabidiol stated on the label. And about one in five contained THC.

Licensed farmers can now grow the plant, as long as it contains less than 0.3% THC. The result? CBD is turning up in everything from oils and lotions to coffee and cookies.

A false-positive on a drug test could have implications for people at work, and in their medical care. For example, some health care organizations do not allow patients to start opioid painkillers if they use marijuana.

According to Robert Fitzgerald, a professor at the University of California, San Diego’s Center for Advanced Laboratory Medicine, “It would depend on the purity of the product.”

On the positive side, he noted, immunoassays are only screening tests. They would be followed up by “confirmatory testing” that does distinguish THC from other compounds. But you could still have a problem if your cannabis product was contaminated with THC, Fitzgerald said.
