Senate majority leader Mitch McConnell signed off on the final version of the 2018 Farm Bill on Monday . . . and he used a pen made of marijuana’s non-psychoactive cousin, hemp, to do so.

The senator has been the leading proponent of an industrial hemp legalization provision, which recently made its way into the final version of the wide-ranging agriculture legislation.

“Making it official with my hemp pen,” McConnell wrote in a tweet that includes video of him signing off on the proposal. “Proud to have served as conferee on Farm Bill & to fight for Kentucky priorities.”

Making it official with my hemp pen!🖋️ Proud to have served as conferee on #FarmBill & to fight for #Kentucky priorities. With today's signature, my provision to legalize industrial #hemp is 1 step closer to reality. Looking forward to voting YES on this bill & sending to @POTUS pic.twitter.com/8ypwBebXy7
