Arkansas voters won’t get to weigh in on a ballot initiative to expand medical marijuana after the state Supreme Court ruled the measure didn’t fully explain what it would do, tossing out the initiative just two weeks before the election.

It’s too late to remove the measure from the ballot — early voting began Monday — so the court has ordered election officials not to count any votes cast on it. The proposed constitutional amendment would have broadened the definition of medical professionals who can certify patients for medical cannabis, expanded qualifying conditions and made medical cannabis cards valid for three years.
