A more likely secondhand exposure scenario is a positive marijuana hair test. This results from direct contact with marijuana paraphernalia or from another person having THC on their hands.
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.
CBD oil is usually marketed as THC-free, but that's not always the case. Full-spectrum CBD oils contain other cannabinoids, which may include THC. Isolate products may be contaminated with THC, as well.
CBD Oil Breakdown in the Digestive System
Most CBD products are made from hemp, not marijuana.
Use the utmost caution and do your research when purchasing a quality CBD oil product to ensure its purity, especially if you need to undergo a drug screening.
A CBD isolate is a pure compound with no other active compounds or cannabinoids. The full-spectrum compounds may include other active chemicals, such as cannabinol and cannabis terpenes (the part of the plant that gives the plant its aroma).
A Word From Verywell

Hemp also contains many cannabinoids, which is a name for the compounds found in cannabis. CBD is only one example.
CBD might follow the same range. However, this all depends on things like dosage, metabolism, size, body fat, and more.
Since CBD is federally legal and doesn’t impair or artificially improve athletic performance, there is no reason organizations need to test for CBD. It would be a waste of time and money.
There’s a massive issue with having high-THC and low-THC cannabis chemovars growing in the same state. The layout often leads to cross-pollination, affecting THC levels of industrial hemp.
Follicle tests have the longest range, with THC metabolites detected up to three months after consumption. CBD’s timeframe, however, remains a mystery.
How Long is CBD Detectable in Hair?
Again, CBD won’t show on a standard drug test because it’s not a concern for employers or law enforcement. However, choosing the wrong CBD oil, such as full-spectrum CBD oil, could show positive for THC.
Even worse, many of these products “contained a significant amount of THC.” This is a huge problem considering CBD oil is famous for treating certain forms of childhood epilepsy. Inadequate or deceptive labeling means some parents could be accidentally giving THC to their kids.
A 2012 study in the Iranian Journal of Psychiatry found THC detectable in the blood for three to four hours. However, this doesn’t mean it’s out of your system – not by a long shot.
Does CBD Oil Show Up On A Drug Test?
According to one 2018 study from Frontiers in Pharmacology , CBD has a half-life of two to five days. However, all this means is you’ll eliminate half of the CBD within that time period.
Depending on several factors, CBD could remain inside you for days or weeks.
