The Supreme Court sided with a former commercial truck driver Wednesday who was fired after failing a drug test he said was caused by a “CBD-rich medicine” in a decision that could make it easier to sue companies under organized crime laws.

Douglas Horn sued the manufacturers of a CBD product called “Dixie X” that the companies proclaimed included no THC, the psychoactive ingredient in marijuana. Horn took the product to manage debilitating pain after a serious accident, but he later failed a drug test and was fired. The Supreme Court’s decision will allow Horn’s case to move forward in lower courts.

Justice Amy Coney Barrett wrote the opinion for a 5-4 majority that included both liberal and conservative justices.
