Editor’s note: Ohioans in November will vote on whether to make marijuana legal for medical and recreational use. ResponsibleOhio has proposed what’s become a controversial ballot measure; it’s been reported that the group of investors in marijuana cultivation and sales will spend up to $20 million to campaign for its passage. Already, 23 states have legalized the sale of marijuana for medical use and four states allow pot for recreational use. After this year’s Ohio’s vote, the country could see an even greater movement to end the prohibition on marijuana through state, rather than federal, legislation. “I actually consider 2016 to be what I call the game-over year because there’s a good chance that a bunch of states will legalize marijuana,” said Bill Piper, director of the Drug Policy Alliance’s office of national affairs.
