On November 25, 2019, the U.S. Food & Drug Administration (FDA) announced that it had issued warning letters to 15 U.S. businesses engaged in the sale of products containing cannabidiol (CBD); that it had published a revised Consumer Update detailing safety concerns about CBD products; and that it “cannot conclude that CBD is generally recognized as safe (GRAS)” for use in human or animal food. These actions and statements by FDA cut against industrywide hopes that FDA might soon realign its enforcement policy in light of market realities.
