COLUMBUS, Ohio — If Ohio voters approve a constitutional amendment legalizing marijuana, don’t expect to be able to drive past fields of cannabis sparkling in the Ohio sun.

Instead, a group seeking to legalize marijuana through a November 2015 ballot initiative plans to grow cannabis under hundreds of acres in indoor facilities across the state.

Ballot initiative language released Monday by ResponsibleOhio confirmed earlier reports that growing cannabis would be limited to 10 specific sites owned and operated by investors bankrolling the campaign. The campaign will have to spend millions to persuade voters to legalize marijuana for personal use among adults over age 21 and medical use for “debilitating conditions.”

ResponsibleOhio spokeswoman Lydia Bolander said the sites were chosen for geographic diversity and to meet criteria set in the proposed constitutional amendment. Four are in Southwest Ohio, three are in Northeast Ohio, one is in Northwest Ohio and two are in Central Ohio. The plan also would establish a marijuana research and development center in Cuyahoga County. [Read more at the Cleveland Plain-Dealer]
