Vaping CBD products might lead to a positive urine test for marijuana, researchers report.
A new study tested people after use of cannabidiol (CBD) samples, some containing tiny amounts of THC (the psychoactive ingredient in marijuana). One-third of those who vaped CBD-dominant cannabis had positive urine tests for THC, according to the report in the Journal of Analytical Toxicology.
While packaging of CBD products commonly suggests using them two times a day, researchers warned that people who use more than one dose per day might end up with high enough levels of THC to trigger a positive test because THC accumulates in the body.
