Drug tests are designed to detect THC, the psychoactive component of marijuana, rather than CBD. The Federal Drug Administration (FDA) stipulates that hemp-derived CBD should not contain more than 0.3% THC, but product testing has revealed that this legal limit is sometimes exceeded. Cross-contamination may occur during the manufacturing process, even when THC is present in small quantities. Cannabis is the general term for hemp and marijuana plants, two different varieties of the Cannabis genus.
Full-spectrum oils may contain small amounts of THC, so if you know you'll need to be tested for drugs, avoid these products. It is still possible that traces of THC are present in stomach acid when “less purified CBD productions” are ingested. An analysis conducted by F100 Research on 67 food products containing CBD in Germany revealed that 25% of the samples contained THC above the lowest observable level of adverse effects (LOAEL), of 2.5 milligrams per day. The most common reason why a CBD test doesn't work is that a person is consuming a CBD oil product that contains THC.
To ensure that you don't get a positive result on a drug test, it's important to understand how drug testing works and what research says about using CBD.
How Drug Testing WorksDrug tests measure the presence of THC in your system. Depending on the frequency of consumption, THC can be detected in a test starting from a few days for a single use or more than a month for heavy marijuana smokers on a daily basis.
What Research Says About Using CBDIt's not easy for the consumer to be sure how much THC a particular CBD product contains, as CBD oil is not well regulated. However, there are certain steps you can take to determine if the product you are buying contains the least amount of THC possible.
Unfortunately, there is no guarantee that the labeling will be accurate due to the lack of regulation of CBD products. The bottom line is that if you want to avoid getting a positive result on a drug test, it's best to avoid full-spectrum CBD products and opt for isolated oils instead.
