In 2020, Douglas Horn, a truck driver employed by a logistics company, found himself at the center of a legal battle that would ultimately reach the U.S. Supreme Court. His ordeal began when he decided to try a CBD (cannabidiol) product called Dixie X, produced by Medical Marijuana Inc., which he believed to be completely free of THC (tetrahydrocannabinol), the psychoactive compound in cannabis. This decision was motivated by Horn’s desire to manage chronic pain resulting from injuries sustained in a previous trucking accident.
