The U.S. Senate passed legislation Thursday that would legalize hemp as an agricultural commodity, remove hemp from the federal list of controlled substances, and allow states to regulate hemp as they see fit. The bill’s approval comes after the decades-long, national prohibition on industrial hemp.

The provision, which was included in a farm bill, was sponsored by Senate Majority Leader Mitch McConnel (R-Ky.). The bill passed 86-11.

“I have heard from many Kentucky farmers who agree it’s time to remove the federal hurdles and give our state the opportunity to seize its full potential and once again become the national leader for hemp production. That is why I strongly advocated for this measure to be included in the Farm Bill,” McConnell said in a statement. “For far too long, the federal government has prevented most farmers from growing hemp.”

Along with legalizing the cultivation of hemp, the bill would allow researchers to apply for grants from the Agriculture Department and make hemp farmers eligible for crop insurance.

Before the bill can be put in front of President Trump for signing, the Senate’s version will need to be merged with the version from the House of Representatives.

“Consumers across America buy hundreds of millions in retail products every year that contain hemp,” McConnell said. “But due to outdated federal regulations that do not sufficiently distinguish this industrial crop from its illicit cousin, American farmers have been mostly unable to meet that demand themselves. It’s left consumers with little choice but to buy imported hemp products from foreign-produced hemp.”
