Needham officials may seek a moratorium on the distribution and cultivation of medical marijuana in town, citing a lack of guidance from state health officials on how it should be regulated.

“It is very clear to us that the voters have spoken,” Jane Fogg, a member of the Needham Board of Health, told selectmen Tuesday night. “What’s also very clear to us is we have a responsibility to do this safely and properly. We’ve all been suffering from a lack of clear direction from the state.”
