The Journal of Analytical Toxicology features a new study by researchers at John Hopkins University. The study, titled Urinary Pharmacokinetic Profile of Cannabinoids Following Administration of Vaporized and Oral Cannabidiol and Vaporized CBD-Dominant Cannabis assesses the occurrence of positive drug tests as a result of using CBD products.
The study featured six participants who took vaping cannabis products that featured 0.39% percent of THC and 10.5% CBD. After vaping less than one gram of the products, two of the participants tested positive.
Ryan Vandrey, Ph.D, an associate professor of psychiatry and behavioral sciences at John Hopkins University School of Medicine, stressed the importance of making the public aware that use of CBD products can lead to a positive drug test.
