Consumers who want to be extra-cautious and use CBD with no THC should shop for a broad-spectrum oil or a CBD product that contains pure CBD isolate. Broad-spectrum oil is refined to exclude THC, while CBD isolates contain no THC or other plant-based cannabinoids. To ensure that your CBD contains no THC, it’s important to source products from reputable manufacturers that provide a certificate of analysis from a third-party testing lab.
Bottom line: Apart from the one study that showed CBD was no longer detectable in urine after 24 hours, there isn’t much research on drug testing for CBD in urine.
Inhalation is also an effective delivery method for CBD due to its rapid absorption and the efficiency of the lungs at transferring CBD into the bloodstream. Whether you’re smoking a high-CBD strain or taking a draw from a CBD vape pen, the interaction with the body remains the same. When CBD is inhaled, the cannabinoids are sent directly to the lungs, where they are rapidly absorbed into the bloodstream and put into circulation.
Bottom line: While the time that CBD is detectable in the body will depend on the aforementioned factors, we can deduce that CBD will likely leave the system after a week or two.
Will CBD show up on a drug test?
Bottom line: Existing evidence suggests that CBD reaches peak blood concentration within three minutes after inhalation, meaning any effects should be felt shortly after use. The effects should then last anywhere from 45 minutes to a couple of hours.
It’s important to note that, while existing evidence shows us that CBD can definitely be detected in the body for a certain period of time, most drug tests specifically look for the presence of THC. Therefore, accurate information on how long CBD stays in the body remains limited compared with information on THC.
A 2018 review of existing CBD studies found that the estimated half-life of CBD was two to five days for those who took a daily oral dose. Other delivery methods delivered varied half-lives.

So what does research say? A 2018 review of existing studies found that the half-life of CBD is two to five days when the compound is taken orally. Other administration methods have various half-lives.
Even though CBD products containing less than 0.3% THC are legal federally, there is still some risk, especially for those who are drug tested to maintain their employment. Because there’s much to learn about how CBD interacts with the body, some are on the fence about trying these products.
Will CBD Make You Fail a Drug Test?
CBD can stay in your system anywhere from a day to a few weeks. The timeframe is highly dependent on various factors, including metabolism, dosage, consumption method, and frequency of use.
