Another State Zeroes In on Legalizing Marijuana Constitutional amendment will appear on November ballot By Michael Harthorne, Newser Staff Posted Aug 12, 2015 7:15 PM CDT 80 comments Comments Ohioans will vote on legalizing marijuana this November. (Shutterstock) (Newser) – Ohio could become the fifth state in the country to legalize recreational marijuana after it was announced today that backers collected enough valid signatures to qualify for the Nov. 3 general election, Time reports. ResponsibleOhio, the organization behind the proposed constitutional amendment, collected 320,267 signatures, nearly 15,000 more than needed, notes the Cincinnati Enquirer. ResponsibleOhio plans to spend at least $20 million to sway voters in what appears to be the best-financed marijuana legalization effort in US history. Yet many are speaking out against the push, including Republicans like Gov. John Kasich and Attorney General Mike DeWine, who says it's "a stupid idea." Marijuana is already legal in Washington, Colorado, Alaska, Oregon, and Washington, DC.
