Part of Ohio's new medical marijuana law that sets aside a piece of business for minorities appears to be unconstitutional, according to legal scholars who spoke to the Associated Press. The amendments require at least 15 percent of Ohio's cultivator, processor, retail dispensary and laboratory licenses to go to minority-owned businesses, so long as an adequate number apply. Constitutional experts say such rules fail to hold up in court, absent documented proof of past or likely discrimination - which is unavailable for a brand new market.
