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.
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.)
Factors in CBD Oil Showing on Drug Screen
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.
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:

Cannabis is the umbrella term describing hemp and marijuana plants—two different varieties of the cannabis genus. Both marijuana and hemp can be described as cannabis plants; however, it is important to note that they are still two separate plants.
Does CBD Oil Contain THC?
CBD is one of many active chemical compounds in the cannabis plant. One reason it’s gaining momentum in popularity is because it is said to lack the component of the plant that causes a person to get high, which is called THC (tetrahydrocannabinol).
The primary difference between hemp and marijuana is that hemp is nearly void of THC. In fact, a cannabis strain must contain less than .3 percent THC to be classified as hemp. This is the reason hemp can be legally sold as various products.
CBD oil extracted from hemp is not supposed to have any more than .3 percent of THC. However, it’s not uncommon for sellers to mislabel their products as THC-free hemp when in reality, it’s a low-quality oil extracted from marijuana, which does contain THC.
