does cbd oil show on a drug test

The following variables affect the amount of time that marijuana (THC) and its metabolites remain detectable in the urine or other biological samples:

An estimate of the length of time marijuana (THC) is detectable in urine is:

Official Answer

There are two main types of urine drug tests: screening and confirmatory tests. Immunoassay screening tests can be conducted on-site (point of care testing) or in a laboratory and allow large numbers of tests to be performed at once with relatively rapid results, providing an initial estimate of the presence or absence of drugs. There are three main types available, and all use antibodies to detect the presence of specific or classes of drug metabolites. Unfortunately, this can mean that substances with similar characteristics may be detected, resulting in false-positive results.

Theoretically, CBD should not show up on a drug test. However, because most CBD products are classified as a supplement, it is not regulated for safety and purity. This means that contamination of the CBD with THC (tetrahydrocannabinol) may and does occur, and this may show up on a drug test, depending on the cutoff level of the test and other factors listed below.

If you want to pass a drug test, don't take CBD; or if you are taking it legally within your State's laws, then declare it (however it still may be contaminated with THC unless brought by a reputable supplier who guarantees it to be THC-free).

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.

If you are concerned that THC in your CBD oil or other CBD product may show up on a drug test, you may be able to reduce the chance of that occurring, though there is no guarantee. Some of the factors that may increase the likelihood of a failed drug test are:

Factors in CBD Oil Showing on Drug Screen

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.

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.
