does cbd oil show up in a blood test

Generally, THC is only detectable in your plasma for about five hours after you take it. However, THC metabolites and, therefore, CBD can be present for up to a week.

Urine tests are the most popular and common method of drug screening for employers. The detection-window for THC through urine tests can vary widely.

This can be particularly worrisome if you are searching for jobs or need to consent to drug screenings for other reasons (e.g., being on parole). It’s a common misconception that CBD and THC are the same; while CBD is a natural supplement, it’s still possible for the THC metabolites to be detected during drug screenings.

How Long Does CBD Stay In Your Saliva?

It’s also worth noting that because CBD products are not regulated by the FDA, it’s possible that you could be taking CBD that is mixed with other cannabinoids, which could increase detectability. Also, it’s worth noting that the more frequently you use cannabis products, the wider detection windows become.

Just because you no longer feel the effects of CBD doesn’t mean it is no longer detectable. The half-life of CBD is between 18 and 32 hours. However, it can be detectable on lab tests for much longer than that.

Different drug tests have different cut-off levels. Legally, hemp products can contain up to 0.3% of THC.

It hinges mostly on the dose you took and your frequency of use. Typically, these metabolites can show up on a urine test anywhere between three days to two weeks after the last time taken.

Swallowing CBD oil prevents the cannabinoid from entering the bloodstream right away. Instead, it will travel first through the digestive tract and eventually on to the liver, where it will be broken down before finally reaching the bloodstream.

Cannabidiol (CBD), a non-intoxicating compound found in the cannabis plant, may potentially relieve mild pain and anxiety. While many people are using CBD for these potential benefits, the fear of failing a drug test looms large for others. Because even with the legalization of hemp-derived CBD products in the US, there’s still some uncertainty about how CBD interacts with the body.

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: 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.

Topical products that claim to contain CBD—like shampoos, cosmetics or creams—should not cause any reaction during a drug test because they do not enter the bloodstream. In the case of CBD oils, gummies, teas or transdermal patches, the situation is more complicated. In a test of 84 CBD products obtained online, 18 contained THC.

CBD has taken off as a natural remedy for a variety of ailments. CBD products like CBD oil can be made from either the hemp plant or the cannabis plant, which are closely related varieties of the same cannabis species, Cannabis sativa. CBD products contain a cannabinoid—a chemical—called cannabidiol, which does not make you high. The substance in marijuana that causes a buzz is a different cannabinoid, called THC, or tetrahydrocannabinol.

Factors in CBD Oil Showing on Drug Screen

The legality of CBD products can be confusing. CBD products made from certain cannabis plant varieties are legal only in states where marijuana is legal, due to the potential THC content. CBD products made from hemp variety plants are legal throughout the United States as long as they contain less than 0.3% of THC and do not make any medical claims. (A hemp plant is defined as Cannabis sativa that contains less than 0.3% THC.)

CBD products can still be problematic, however, when it comes to drug testing. Though drug tests screen for THC, not CBD, many CBD products contain a trace amount of THC which will be detected in your bloodstream during a drug test.

THC can be detected in a urine test for up to 15 days, depending on how often and how much you use. It leaves the bloodstream in about five hours, but substances your body makes from THC (THC metabolites) can show up for as long as 7 days. CBD tends to stay in the bloodstream from 2 to 5 days, depending on dosage and frequency. If you have been using CBD for a while, it can stay in your body for up to 30 days or more.
