Marijuana use study sought by backers, foes of legalization

BOSTON – At odds over the prudence of legalizing retail sales of marijuana in Massachusetts, people on both sides of a proposed ballot question to do just that agree with the idea of measuring current pot use.
"What we've seen happen in other states is that they don't have existing baseline data on recreational marijuana use and it becomes very difficult for both sides to have honest conversations about the effects and impacts" of legalization, said state Rep. Hannah Kane, a Shrewsbury Republican who opposes the proposed ballot measure.
