cbd vape oil show up on drug test

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.

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.

What are the odds that CBD oil users will test positive when subjected to illicit drug screenings, and what can be done to prevent it?

A Word From Verywell

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.

When a drug test is performed, the active chemical in marijuana that gets detected in a positive screening is THC. However, most people are under the impression that CBD oil is THC-free.

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.

In a study conducted by researchers from the Lautenberg Center, researchers discovered that CBD was more effective for treating inflammation and pain when used with other cannabis plant compounds derived from a full spectrum product over a CBD isolate product alone. This is one reason that full spectrum products (those containing THC) are popular.

Recognized as the preferred method for cannabis drug testing, urine screenings are often used as a benchmark to detect for cannabis use. Most urine tests utilize a specific sensitivity for the cutoff concentration of THC-COOH. The most common cutoff concentration point is 50 nanograms per milliliter (ng/mL), as suggested by the Substance Abuse and Mental Health Services Administration (SAMHSA).

Upon inhalation, active THC can be found in the bloodstream within a matter of seconds and can be detected in plasma for several hours, depending on the frequency of use and dosage. According to a 2004 review published in the journal Therapeutic Drug Monitoring, the plasma concentration of THC peaks just three to eight minutes after inhalation and then decreases quickly with a half-life of about 30 minutes. The study claims that THC is detectable in blood for about five hours, but the THC metabolite THC-COOH has a detection time of up to 25 days.

Some concerned consumers may wonder if a CBD-specific test exists. Technically, since CBD is a chemical that your body metabolizes, a specific test could be developed to detect it. But the average drug test is not designed to identify usage of CBD or CBD oil specifically.

There is mounting evidence that hair follicle drug testing methods are not able to accurately detect marijuana. Research published in the journal Scientific Reports suggests that the presence of THC and THC metabolites can be transferred to the hair follicles of non-consumers through contact with hands, sweat, or exhaled smoke.

Whichever method, or methods, you choose, be sure to buy from a reputable source and check the label carefully. Since the Food and Drug Administration (FDA) hasn’t established guidelines for CBD products, it’s buyer beware. Avoid any product making health claims like that it cures or treats anything specific. Most reputable CBD producers typically include the following information on their product labels:

If drug testing is a concern but you still want to consume CBD for any of its reported health benefits, you absolutely can. Follow the instructions below based on your preferred consumption method and choose CBD products accordingly.
