does cbd vape oil show up on a drug test

Topical CBD products like ointments, lotions, or balms don’t enter the bloodstream in a way that would be picked up by a drug test. Even if it contains the federally legal amount of 0.3% THC, topicals are still safe as far as drug testing is concerned.

A 2005 review published by the National Drug Court Institute states that THC detection times rarely exceeded 30 days. According to a May 2017 review published in Mayo Clinic Proceedings, weed can be detected in urine for up to three days in occasional users, five to seven days in moderate users, 10 to 15 days in daily users, and more than 30 days for chronic users who consume multiple times a day.

For example, if someone smokes a joint and exhales near someone who doesn’t consume cannabis, THC can be transferred to the non-smoker’s head or body hair. The same study found that, after giving participants 50 milligrams of THCA every day for one month, no THC was found in the hair specimen samples, but THC-COOH was still detected. As for the detection period, the hair follicle drug test timeline is much broader than with urine and blood tests, sometimes detecting the presence of THC up to 90 days after use.

THC and its metabolites can also be detected in the saliva of occasional and chronic users. A 2014 study published in the journal Drug Testing and Analysis looked at cannabinoids in oral fluid and found that THC metabolites were detectable in the saliva of occasional users for one to three days and chronic users for up to 29 days.

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.

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

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.)

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.

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 take CBD oil, there are measures you can take to try to prevent failing a drug test.

In theory, getting a false positive on a drug test from CBD oil should be relatively impossible from pure CBD oil containing less than .3 percent THC. However, because CBD oil is not very well regulated, there is no guarantee that a product contains pure CBD oil, or that its concentration is at a safe or effective level.   It is best to use utmost caution and do your research when purchasing a quality CBD oil product to ensure its purity, especially if you need to undergo drug screenings.

Very small amounts of THC present in the material that CBD is extracted from can get into the CBD oil in high enough amounts to result in a positive drug test. This scenario may be more apt to occur when CBD oil is purchased from cannabis dispensaries in places where cannabis is legal, as opposed to an online retailer.

How to Avoid a Positive CBD Drug Test

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 (cannabidiol) oil is a popular product for everything from pain control to anxiety to promoting sleep. However, with the rise of CBD comes the concern about failing a drug test due to detection of CBD oil. News stories are emerging across the country involving famous sports players, employees of companies, and others who have gotten positive drug screening results for the presence of THC—the psychoactive component of marijuana —even though CBD oil is said to be THC-free.
