Luxor Scientific Receives Provisional Patent for CBD/THC Differentiation Testing. Luxor offers a patent pending supplemental test that separates THC (the psychoactive component of marijuana) from CBD (the legal and popular dietary supplement that purportedly has a number of healthy benefits). We often find that individuals take CBD products, and fail typical drug screens as a result. This test separates the two compounds and gives employees the greatest opportunity to fall into compliance with the employer’s policy.
