(ONN) – Voters will decide in November whether Ohio should become the 24th state to allow recreational marijuana.

If passed, the measure would allow adults 21 and over to buy and possess up to 2.5 ounces of cannabis and to grow plants at home.

A 10 percent tax would be imposed on purchases, to be spent on administrative costs, addiction treatment programs, municipalities with dispensaries and social equity and jobs programs.

A study from Ohio State University found that the plan could generate about $275 million to $450 million in tax revenue after five years.

Last year five states had the issue up for a vote: Arkansas, Maryland, Missouri, North Dakota and South Dakota – and the measures were approved in Maryland and Missouri.
