That may be the DEA's consistent position but whether it's a lawful position is in dispute. Also from the article:

Robert Hoban, a Colorado cannabis attorney and adjunct professor of law at the University of Denver, raised the notion that the rule itself may not be lawful. “This action is beyond the DEA’s authority,” Hoban told Leafly in an interview late this afternoon. “The DEA can only carry out the law, they cannot create it. Here they’re purporting to create an entirely new category called ‘marijuana extracts,’ and by doing so wrest control over all cannabinoids. They want to call all cannabinoids illegal. But they don’t have the authority to do that.”
