From the Document: "Changes enacted in the Agriculture Improvement Act of 2018 (P.L. 115-334; 2018 farm bill) removed long-standing federal restrictions on the cultivation of hemp. Hemp is a form of Cannabis sativa,the same plant as marijuana, grown for non-psychoactive purposes. It is an agricultural crop regulated by the U.S. Department of Agriculture (USDA). AlthoughUSDA regulates hemp production, the 2018 farm bill explicitly preserved the authority of the Food and Drug Administration (FDA) under the Federal Food, Drug, and Cosmetic Act (FFDCA, 21 U.S.C. §§301 et seq.) over certain hemp-derived products."
