When the Farm Bill passed in 2018, it legalized growing hemp as an agricultural product, removing it from the Controlled Substances Act (CSA). The bill defined hemp as the plant species Cannabis sativa L. with a delta-9 tetrahydrocannabinol (THC) concentration of not more than 0.3 percent on a dry weight basis. In easier terms, this means that it became legal to grow hemp as long as it didn’t have more than 0.3% THC, so it can’t make anyone high.

To date, 49 states have passed legislation to allow for the cultivation of hemp for research or to establish hemp production programs. Possession of hemp-derived CBD products also varies from state to state. This is because the Farm Bill leaves it to the individual states to legalize possession of hemp products.

Idaho prohibits the cultivation of hemp and Washington D.C. has no established industrial hemp program. Mississippi, long a hold-out, passed legislation in June 2020 allowing for the cultivation of hemp. South Dakota, also one of the last states to approve hemp, passed legislation in March 2020 allowing for cultivation.
