$HEMP There are now 41 states in the nation that have legalized hemp, and at least 39 have allowed for hemp cultivation and production programs. The hemp-derived cannabidiol (CBD) market is expected to hit $591 million this year. There are no signs of slowing, either, as the market is projected to grow 40 times this size—to $22 billion by 2022, according to a report by Brightfield Group.
