Washington Post-University of Maryland poll conducted in September 2016 showed that 61% of Marylanders — and 64% of likely voters — support ending marijuana prohibition. 

That survey is the most recent statewide polling on the issue, but as support for legalization has increased nationwide, support in Maryland 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 73% 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.
