The Supreme Court agreed on April 29 to take up the case of a truck driver who lost his job after testing positive for tetrahydrocannabinol (THC), the psychoactive chemical compound in marijuana that produces a high, after consuming a hemp-based product that was advertised as THC-free.
The case comes as more states are legalizing marijuana and marijuana-derived products and the popularity of products made from marijuana, also known as cannabis, is rising. Cannabidiol (CBD) products, often in the form of candy gummies, are also becoming more popular. Such products contain hemp, a relative of marijuana, but not THC, and are not impairing.
