Cannabidiol (CBD) has recently surged into the therapeutic spotlight for its perceived anti-inflammatory, anti-anxiety, pain-relieving, and seizure-suppressing properties. It can be found in health and wellness aisles across the world — perhaps even at your local Walgreens or CVS — and comes in many forms, some of which include CBD oil, tinctures, edibles, elixirs, and more.

CBD is a non-intoxicating compound found in cannabis, which some say provides the benefit of relaxation without the high that THC provides.

Although hemp-derived CBD products are available in states where recreational cannabis isn’t legal, some people might worry whether their use of CBD oil will show up on a drug test. Even in states where it is legal to buy THC-heavy cannabis from a retail store, some employers still screen employees for cannabis use. It’s a valid concern considering that even CBD products derived from hemp are legally permitted to contain traces of THC, 0.3% or less to be exact, perhaps leaving some consumers to wonder whether there’s a small amount of THC in their CBD oil — and whether that will show up on a drug test.

“I think that people who are afraid of testing positive should use isolate that is third-party tested to have no THC or extremely minute trace amounts that result in no THC. That’s the simple and safest thing,” said Dr. Joseph J. Morgan, Professor of Cannabis Education at the University of the Sciences in Philadelphia and medical adviser.

While there are certain CBD products, such as distillate and crystalline, that contain zero THC, the fears of inexperienced consumers may still persist. Like most things in the constantly evolving cannabis space, there are a number of factors to consider.

Should you worry about CBD oil showing up on a drug test?

In most cases, it’s highly unlikely that CBD oil will show up on a drug test. Most employment drug tests specifically look for the presence of THC or THC metabolites. Most employers abide by the guidelines set forth by the Substance Abuse and Mental Health Services (SAMHSA), which includes detection for THC but not CBD.

But what if your CBD oil contains small traces of THC? Many top CBD manufacturers have products with no presence of THC. Although hemp-derived CBD products are legally allowed to contain a maximum of 0.3% THC, some prospective consumers may still be reluctant to try CBD that contains even a small amount of THC. Thankfully, there are ways to create hemp-derived CBD products without any hint of the intoxicating cannabis compound.

For instance, producers can isolate CBD compounds after the oil is extracted from the stalks and seeds from hemp plants. This process leads to pure CBD, effectively eliminating any THC and other plant-based constituents from the end product. Once isolated, the CBD can be mixed with liquid oils that contain fatty acids to improve absorption.

But how can you tell how much THC, if any, might reside inside your CBD oil? Can you really trust everything the label on the side of the bottle? The safest bet is to look for well-known CBD products that are independently tested.

“Buy from reputable forms that are third-party tested that have batch numbers, lot numbers, and retained batch samples. If they claim that either that their plants are genetically engineered for no THC or they use methods that purge THC, to make sure that that’s third-party validated,” Morgan said.

There are also different types of drug tests that can be used, all of which present different detection thresholds. For instance, a hair test is made to detect habitual substance use, so it will probably not raise any red flags even if you are consuming CBD oil that has low levels of THC.

Urine and oral drug screenings have a lower threshold for detection, so there is slightly more risk with these tests, according to a December 2018 article published in Vice. While it’s possible that the small amounts of THC that exist within a CBD product could accumulate and show up in a drug test, it’s still highly unlikely.

Under the SAMHSA framework, the cutoff limit for the presence of THC is 50 nanograms per milliliter. Following these guidelines, if an extremely high dose of 2,000 milligrams of CBD oil that contains 0.3% THC was consumed, there’s a slim chance of receiving a “false positive” result on a urine screening.

Is there such a thing as a CBD oil drug test?

While it may be uncommon for anyone to screen for the presence of CBD, does a CBD oil drug test even exist? Technically, since CBD is a chemical that your body metabolizes, a specific test can be developed to detect it. But the average drug test will not identify any usage of CBD oil.

To obtain a CBD oil drug test, an employer or entity would have to pay a testing company an additional charge to change their testing regimen to include CBD. When you consider that this non-intoxicating compound won’t get you high or impair your ability at work, there’s really no need for a CBD oil drug test.

If you’re concerned that using CBD-infused products will cause you to fail a drug test, there are certain precautions you can take to ensure that no THC enters your system. Look for producers who create high-quality CBD products that contain zero THC, such as distillate or crystalline products.

Some CBD products may yield cannabis-positive urine drug tests

In a study of six adults, Johns Hopkins Medicine researchers report evidence that a single vaping episode of cannabis that is similar in chemical composition to that found in legal hemp products could possibly result in positive results on urine drug screening tests commonly used by many employers and criminal justice or school systems.

The U.S. government defines hemp as any crop of cannabis containing 0.3% THC or less in dry weight. THC (delta-9-tetrahydrocannabinol) is the substance in cannabis that confers a “high” and produces the subjective and cognitive effects that are typically synonymous with cannabis. The 2018 U.S. Farm Bill legalized the production and sale of hemp, and now as a result, consumer hemp products, such as oils, vaping cartridges and hemp flowers for smoking can be legally purchased in specialty stores, general retail stores and through websites across the U.S.

Hemp is now increasingly finding use in medicine and wellness markets, particularly for its component CBD, short for cannabidiol, which is one of the more than 100 cannabinoids found in the cannabis plant. According to New York-based investment bank Cowen & Co., the market for CBD last year ranged from $600 million and $2 billion in sales. Despite the size of this booming industry, it remains largely unregulated.

In a paper published Nov. 4 in the Journal of Analytical Toxicology, the researchers report that two out of six study participants tested positive after vaping cannabis that contained 0.39% THC using urine testing methods that are consistent with testing frequently performed for employment-related or criminal justice-related urine drug testing programs. Though the cannabis used in this study does not currently meet the federal definition of hemp, the THC concentration of 0.39% exceeds federal regulation by just 0.09%.

“People who use legal hemp products for medical intent rarely just use them once as we did in this study, and prior studies show that THC and its metabolites may accumulate with repeated use,” says postdoctoral fellow Tory Spindle, Ph.D., a researcher in the Behavioral Pharmacology Research Unit at the Johns Hopkins Bayview Medical Center. “What this means is that people need to be wary of single-dose or cumulative THC exposure and be aware that these now legal products may cause an unexpected positive result on a drug test.”

“Because the market for CBD products is so new and the popularity of use is growing so quickly, we want the public to be aware that a positive drug test is possible,” says Ryan Vandrey, Ph.D., associate professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine. Vandrey and his collaborators at the University of Pennsylvania previously showed in a JAMA study that 21% of CBD/hemp products sold on the Internet contained THC, even though it wasn’t listed on the product labels. “I have a hard time finding anyone who hasn’t used a CBD product at least once, but most are completely unaware of the possibility of THC exposure or a positive drug test as a result of using these newly legalized products,” says Vandrey.

trials demonstrated CBD to be an effective treatment for two rare forms of pediatric epilepsy, however, there is currently insufficient evidence to support use for any other health condition according to the U.S. Food and Drug Administration. Despite this, CBD product suppliers and consumers claim benefits of CBD for a wide range of purposes, including everything from anxiety to insomnia to general wellness. CBD products can be swallowed in the form of an oil/tincture, eaten in a food product (e.g., gummy bears), inhaled using “vape pens” similar to electronic cigarettes, or applied topically to the skin in a cream, patch, balm or gel.

For the current study, the researchers recruited three women and three men with an average age of 31 years old. One participant self-reported as African American and the rest as white.

The batch of cannabis used in this particular study contained 10.5% CBD and 0.39% THC, a 27 to 1 ratio of CBD to THC that is similar to what is often found in legal hemp/CBD products. In the study, research volunteers vaporized a little less than 1 gram of cannabis, which contained a total dose of 100 milligrams of CBD and 3.7 milligrams of THC. To vape the cannabis, heated cannabis vapor was collected into a balloon that was then inhaled by the participant.

In addition to vaping the high CBD/low THC cannabis, study volunteers also were given pure CBD in a capsule, vaporized pure CBD and placebo (a mock CBD pill and vaporized cannabis in which CBD and THC had been removed) in three other dosing sessions, one week apart from each other. In all active drug conditions (excluding placebo), the CBD dose delivered was 100 milligrams per session.

The drug testing cut-off used to determine a “positive” result in this study was a “screening” concentration of at least 50 nanograms per milliliter of THCCOOH, a metabolite used to indicate whether someone has used cannabis, in the urine sample using an on-site “dipstick” test. A positive on that test was then “confirmed” at a 15 nanograms per milliliter cut-off of THCCOOH using a more sensitive test method.

Two of the six participants who vaped the low-THC/high-CBD cannabis tested positive for THCCOOH.

No positive urine drug test results were observed in the other test sessions (pure CBD capsules, pure CBD vape or placebo).

“These results suggest that pure CBD, used once by itself, will not cause a positive drug test,” says Vandrey. Adding to this, Spindle points out that it “does not take much THC exposure to trigger a positive test for some people.” There may be variation from person to person in drug metabolism and puffing behaviors such as inhalation depth, which might contribute to the breakdown or buildup of cannabinoids in the body, the researchers say.

The team says they plan to repeat their studies using products that fall within the current federal hemp regulations with respect to THC content, and additionally study the impact of repeated CBD/hemp exposure on drug testing outcomes.

Other authors on the study were Edward Cone and George Bigelow of Johns Hopkins, David Kuntz of Clinical Reference Laboratory, John Mitchell of RTI International and Ronald Flegel of the Substance Abuse and Mental Health Services Administration (SAMHSA).

This research was supported by SAMHSA and the National Institute on Drug Abuse (T32DA07209).

A small study concludes that caution is warranted for users of ‘high CBD, low THC’ cannabis products.
