As the CBD craze sweeps the nation, some users may wonder whether the cannabis extract can make them fail a drug test. A preliminary study suggests the answer is "no" -- at least if the CBD is pure.
Researchers found that CBD, or cannabidiol, did not react with either of two commercially available tests used to screen for marijuana use. However, another cannabis compound -- cannabinol (CBN) -- did.
CBD and CBN are two of many chemicals found in cannabis plants. They differ from THC, the source of the marijuana "high." CBD is present in marijuana but more abundant in hemp -- cannabis plants that have little THC. CBN, meanwhile, is a THC derivative.
If you think CBD products are suddenly everywhere, you're right: There has been an explosion since last year, when Congress lifted a decades-old ban on growing hemp.
