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

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.
Hemp Seed Oil is used for pain relief, anxiety relief, cosmetic reasons, and as a dietary supplement. (5)
Let’s get started.
Now, back to the study
Drug Testing Process
The medical study selected for this article is conducted by a highly reputable scientific organization.
None of the study participants taking the hemp seed oil capsules (aka cannabis Sativa oil) failed the short-term drug test or long-term drug test in this study. (1)
It is widely believed that consuming hemp seed oil will not cause you to fail a drug test…but is that true? New research has the answer. (2)
The legal definition of hemp is really simple. If a cannabis plant has less than 0.3% THC, then it is legal federally and considered hemp.
