Backers of a prescription drug discount proposal submitted more than 140-thousand signatures to force the legislature to face the issue. The coalition for affordable prescription drugs gave secretary of state Kenneth Blackwell’s office 143-thousand signatures. The group needs the valid signatures of about 96-thousand registered Ohio voters for the petition to take effect. If the petition is validated, the legislature will have four months from the January sixth start of the session to pass the proposal as a bill. If it fails to do so, backers will have until August to collect the same number of signatures and put the issue before Ohio voters. Under the plan, the state would buy drugs in bulk and negotiate rebates with drug makers.
