Hemp is now federally legal, with states given the opportunity to implement their own laws regarding the cultivation and sale of the hemp plant.
After nearly century of prohibition in the U.S., hemp only recently again became legal to grow and use in the United States under federal law. With the passage of the 2014 Farm Bill, individual states were permitted to implement laws allowing state departments of agriculture and universities to grow hemp for research or pilot programs. The passage of the 2018 Farm Bill, signed into law in December of 2018, removed hemp from the Controlled Substances Act, jumpstarting the sleeping industry. The law made it legal for U.S. farmers to grow, process and sell hemp commercially. It also legalized hemp nationwide for any use. State laws vary on a state-to-state basis.
In 2016, the U.S. hemp market was valued at more than $688 million and is now on track to reach $22 billion by 2022.
