The Ohio House has passed a proposal to legalize medical marijuana in the state. The fast-tracked bill would bar patients from smoking the substance but allow them to use it in vapor form. They could not grow it at home. Under the legislation, a nine member medical marijuana control commission would set rules for cultivating, distributing and licensing cannabis. Communities could opt out of hosting dispensaries. Employers who want to maintain drug-free workplaces would be protected from liability. The bill passed on a 71-26 vote Tuesday. The Senate plans hearing on the measure Wednesday. House leaders said they expect the legislation to reach the Governorâ€™s desk by the end of May. Lawmakers are seeking to head off a proposed November ballot issue supported by the Medical Marijuana Movement.
