Delta 9 is legal according to the federal government. The passage of the 2018 Farm Bill transformed the unregulated market into a booming new, legal market. Suddenly legal Delta 9 products -- derived from hemp plants harvested from industrial hemp farms, and not marijuana extracts -- became legal products overnight. Traditional marijuana is still illegal (except in states for medical and recreational use), but industrial hemp is lawful at the federal level, including Delta 9.
