Supporters of legalizing marijuana in Arizona have submitted more than 250,000 signatures to put a measure on the November ballot.
Representatives of the Arizona Secretary of State's Office on Thursday began counting signed petitions in dozens of boxes collected by the Campaign to Regulate Marijuana Like Alcohol.
Campaign chairman J.P. Holyoak says this is the first step toward ending policies of prohibition.
The initiative needs 150,000 valid signatures by July to get on the ballot.
Under the measure, adults age 21 and older can carry limited amounts of marijuana.
Opponents say the measure lets medical marijuana dispensaries have a monopoly on licenses to sell.
