GRAND JUNCTION, Colo. (AP) — Colorado’s attorney general says the Nebraska and Oklahoma lawsuit that asks the U.S. Supreme court to curtail Colorado’s new recreational marijuana law could have dire consequences for all three states.

Attorney General Cynthia Coffman says if the U.S. Supreme Court sides with the two states that border Colorado, the decision would take away the regulatory system that Colorado has built, while leaving the vote to legalize marijuana intact.

Colorado argued in a response to the lawsuit that Nebraska and Oklahoma filed the case in an attempt to reach across their borders and selectively invalidate state laws with which they disagree.

Coffman said bordering states have to deal with people leaving Colorado with marijuana that is illegal within their borders.
