Can Hemp CBD Make You Fail a Drug Test?

Drug testing is usually done to detect THC, the psychoactive component of marijuana. Depending on the frequency of use, THC can be detected in a test within a few days for a single use or more than a month for heavy marijuana smokers on a daily basis. Fortunately, drug tests don't usually measure CBD since it doesn't cause intoxicating effects and it's not an illegal controlled substance. However, people who consume CBD may still not pass a drug test.

Products containing CBD may be contaminated with THC or may be mislabeled. While it's unlikely that CBD will stop someone from passing a drug test, there's no way to guarantee that. The only way to ensure that you will pass a drug test is to refrain from using any type of CBD product. Be wary of online retailers; researchers have found that 21% of online CBD and hemp products were mislabeled.

This suggests that product mislabeling is quite common in the industry, although more research is needed to confirm whether this is also true for American CBD products. The Food and Drug Administration (FDA) states that products containing more than 0.3% THC are illegal, and the United States Drug Enforcement Agency (DEA) includes them as Schedule I drugs. Cross-contamination may be more likely in the case of manufacturers who prepare products that contain only CBD, only THC, or a combination of both. While some CBD oils claim to be isolated, they may be full-spectrum oils and, in fact, contain more cannabinoids (such as THC) than they claim.

However, CBD products containing more than 0.3 percent THC still fall within the legal definition of marijuana, making them illegal at the federal level, but legal under some state laws. In other words, full-spectrum products include CBD along with terpenes, flavonoids, and other cannabinoids such as THC. Inadvertent exposure to marijuana (through second-hand smoke) is unlikely to be enough for a person to test positive for drugs. According to an open study published in JAMA Psychiatry, the use of so-called “full spectrum” formulations of cannabidiol (CBD) products can cause consumers to test positive for THC, the component of marijuana that causes euphoria.

The person requesting the drug test can request that CBD be added to the list of substances being tested. Some of the most abundant cannabinoids are THC, CBD, cannabigerol (CBG), cannabinol (CBN) and cannabichromene (CBC). Cannabis sativa is an extremely versatile plant that growers cultivate for numerous purposes, ranging from food such as hemp seeds, hemp-based building materials and medicinal and recreational uses. Full-spectrum CBD extracts contain all of the compounds naturally found in the plant from which they were extracted. The bottom line is that, in theory, it is still possible for trace amounts of THC in stomach acid when ingesting “less purified” CBD products.

Depending on the amount of CBD (and therefore THC) you consume, how often you consume it, your body weight, and your diet, THC may build up in your body in just four or six days and test positive for drugs. In conclusion, while it's unlikely that consuming hemp-derived CBD will make you fail a drug test, there's no guarantee that you won't fail one if you do consume it. To ensure that you pass a drug test without any issues, it's best to avoid using any type of CBD product.
