"No official estimates are available of the value of U.S. sales of hemp-based products. The Hemp Industries Association (HIA) reports total U.S. retail sales of hemp products of nearly $700 million in 2016,12 which includes food and body products, dietary supplements, clothing, auto parts, building materials, and other consumer products (Figure 2). HIA claims that U.S. hemp retail sales have increased by about 10% to more than 20% annually since 2011. Much of this growth is attributable to sales of hemp-based body products, supplements, and foods. Combined, these categories accounted for more than two-thirds of the value of U.S. retail sales in 2016.
