Arizona lawmakers want to overhaul the state's medical marijuana law.
One lawmaker wants to shut down dispensaries that use unclear labels for its food products. Another measure would allow colleges and universities to conduct medical marijuana research. A third would allow county zoning ordinances to apply to marijuana cultivation.
Arizona voters approved medical marijuana by about 4,300 votes in 2010.
Marijuana proponents say it's good that the state wants to implement the law, so long as the proposed regulations don't limit medical marijuana access.
The Department of Health Services oversees Arizona's medical marijuana program and regulates dispensaries where patients and caregivers can legally buy marijuana. More than 35,000 people in Arizona have medical marijuana cards.
An effort to repeal the medical marijuana law has not moved forward in the House.
