LITTLE ROCK, Ark. (AP) — The Arkansas attorney general's office has certified the wording of a ballot proposal that would legalize marijuana in Arkansas. The Wednesday opinion opens the way for the measure's sponsor, Robert L. Reed, to begin gathering petition signatures in hope of placing the measure on the ballot. According to the proposal, voters would decide whether to approve making it legal to grow and possess marijuana and all products derived from the cannabis plant. The measure would be a constitutional amendment, which means backers would have to gather 78,133 valid signatures of registered voters to win a spot on the November ballot.
