Ohio voters approved a ballot proposal legalizing recreational marijuana on Tuesday, defying Republican legislative leaders who had failed to pass the proposed law. Passage of Issue 2 makes Ohio the 24th state to allow adult cannabis use for non-medical purposes. The new law will allow adults 21 and over to buy and possess up to 2.5 ounces of cannabis and to grow plants at home. A 10% tax will be imposed on purchases, to be spent on administrative costs, addiction treatment, municipalities with dispensaries and social equity and jobs programs supporting the industry itself.
