Nearly two out of three Connecticut residents support regulating marijuana for adults. A 2015 survey by Quinnipiac University found that 63% of voters support this proposal, with only 34% opposed.

That survey is the most recent statewide polling on the issue, but as support for legalization has increased nationwide since 2015, support in Connecticut may have increased as well.

An even larger majority of Americans believe that the federal government should let states decide their own marijuana policies. A 2017 survey by Quinnipiac found that 71% of voters oppose federal interference with state marijuana laws, meaning many who oppose legalization still believe that the decision should be left up to states.
