Because THC is the chemical that makes people intoxicated, that is what a drug test screens for, not CBD.
Currently, only CBD oil derived from hemp plants is legal in the U.S., based on the fact that hemp contains less than 0.3 percent THC. By law, CBD oil made from hemp cannot contain more than 0.3 percent THC (although pure CBD should not contain any THC at all).
Marijuana, which also produces CBD, contains more than 0.3 percent THC, making it illegal according to federal guidelines.
Theoretically, if you use CBD oil derived from hemp plants, it should be free of THC. Without THC in your system, you will pass a drug test screening for marijuana use.
Just because it’s not likely that using CBD oil will cause you to test positive for THC on a drug test, doesn’t mean that it’s impossible. CBD oil can contain trace amounts of THC. If enough THC accumulates in your system, it will trigger a positive result in a drug screening.
The reason for possible impurities in CBD oil is the fact that the industry is largely unregulated. The Food and Drug Administration (FDA) does not evaluate CBD products to ensure that they only contain the ingredients listed on the label in the proper amounts. This can lead to situations in which hemp-derived CBD oils with more than the legal amount of THC reach consumers.
There are a few reasons that the purity of CBD oil can be compromised by the presence of THC:
Full spectrum CBD retains the full profile of cannabinoids and terpenes found in cannabis, and therefore contains trace amounts of THC. Depending on how much you use, enough THC may accumulate in your system to show up on a drug test. Broad spectrum CBD oil removes any trace amounts of THC, while retaining other cannabinoids and terpenes. CBD isolate is pure, isolated CBD that does not contain any other cannabinoids or terpenes.
So if your CBD oil contains trace amounts of THC, does that mean you will automatically fail a drug test? Not necessarily. There is still a threshold that needs to be met in order for the test to show positive results.
Federal workplace drug testing cutoff values have been established for THC and the other chemicals that indicate the presence of drugs in someone’s system, so that trace amounts do not trigger a false positive.
The thresholds for detection vary based on the type of test:
The only way to be completely sure you won’t fail a drug test is to refrain from using any substances that might trigger a positive result.
However, if you want to try CBD, there are a few steps you can take to ensure your CBD oil is as pure as possible.
It’s important to only buy CBD oils and products from reputable companies. As a new industry with little oversight, the onus is on the brands themselves to be responsible and honest about what goes into their products.
Before purchasing CBD products, research the company’s history, process, location, and reviews. A strong indicator of a company’s trustworthiness and quality is that they have their products tested by an independent third-party lab, and make the results available to customers. Knowing where the hemp is grown can also be an indicator of quality, as the industry is more established and regulated in certain states like Colorado and Oregon.
Always read labels carefully, and contact the company if you have questions about ingredients. Be sure that you are purchasing CBD oil made from hemp, and not marijuana.
Selecting a broad spectrum CBD oil or CBD isolate is safer than a full spectrum CBD oil, which is more likely to contain trace amounts of THC.
While it’s not 100 percent possible to say that using CBD won’t trigger a positive drug test result, these steps can help you use CBD safely and with peace of mind.
