Sample said Quest Diagnostics does not test for CBD. THC, however, is on the lengthy list of drugs they test for.

Why is there THC in my CBD oil?

So CBD from “federally legal” hemp can still consist of up to 0.3% THC. If you ingest very high doses of CBD—in the thousands of milligrams per day—from federally legal hemp oil, that means you may also be ingesting at least 1 mg of THC as well.

There’s also the potential that an older, not uncommon type of analytical method falsely identifies THC in a sample that only contains CBD. That method is gas-chromatography mass-spectrometry with the derivatization agent trifluoroacetic anhydride (TFAA). Tens of thousands of false positives might stem from the error annually, reporter Amanda Chicago-Lewis estimates, but at least there is some recourse—CBD users have successfully challenged a failed drug test for THC if the lab used this specific method, which can result in a false report of CBD as THC.

In fact, recent research has shown that drug tests can’t tell the difference.

How Your Body Processes CBD and Factors That Affect How Long CBD Stays In Your System

Although blood tests are not nearly as common as urine tests for screening for CBD and cannabinoids, they can be used to detect THC metabolites. The reason they’re not the preferred method of drug screening is because of how quickly THC is eliminated from your bloodstream.

How Long Does CBD Stay In Your Blood?

Generally, THC is only detectable in your plasma for about five hours after you take it. However, THC metabolites and, therefore, CBD can be present for up to a week.

While some CBD oils claim to be isolates, they may be full-spectrum oils and actually contain more cannabinoids (such as THC) than they claim.

These compounds were derived from a full-spectrum product rather than a CBD isolate product alone. This is one reason that full-spectrum products (those containing THC) are popular.

Cross-Contamination of THC

Arno Kroner, DAOM, LAc, is a board-certified acupuncturist, herbalist, and integrative medicine doctor practicing in Santa Monica, California.

Drug tests look for tetrahydrocannabinol (THC), which is the element in marijuana that causes a high. CBD oils can have trace amounts of THC even if they're labeled “THC-free.” The FDA does not regulate these products, and mislabeling is common.

Mislabeling of Products

For instance, say that someone who had direct contact with marijuana then touched your hair. You could feasibly receive a false positive on a drug screening that tests your hair.
