"An Ohio initiative that would legalize marijuana for recreational use officially qualified for this November's ballot yesterday"

"the Ohio initiative would set a minimum purchase and possession age of 21. Adults 21 or older would be allowed to publicly possess up to 2.5 ounces of marijuana—the same as the limit in Michigan but higher than the one-ounce maximum in Illinois—and grow up to six plants at home."
