The U.S. Food and Drug Administration (FDA) and the U.S. Federal Trade Commission (FTC) have issued warning letters to several companies for illegally selling food products containing delta-8 tetrahydrocannabinol (THC) that are branded to resemble popular snack products.

Scientists from the U.S. Department of Agriculture’s Agricultural Research Service (USDA's ARS) and North Dakota State University (NDSU) recently found that cattle fed with hempseed cake, an industrial hemp byproduct, retain very low, food-safe levels of cannabinoids in muscle, liver, kidney, and fat tissues.
