COLUMBUS, Ohio (AP) – Backers of an effort to legalize marijuana in Ohio for medicinal and recreational use say they have more than enough signatures to qualify for the 2015 ballot.

ResponsibleOhio said Tuesday they have collected more than the 550,000 valid signatures they need – and met an additional requirement by hitting signature minimums in 70 of 88 counties. State officials still must review the petitions.

Executive Director Ian James said a robust voter registration effort was conducted in tandem with the signature gathering. The group estimates that about 10 percent of petition signers also initiated or updated their voter registrations.

ResponsibleOhio is working to pass the Marijuana Legalization Amendment, which calls for adults 21 and over to be able to buy marijuana, and to grow up to four plants at home.
