Marijuana is being legalized or is legal in four states and the District of Columbia. Perhaps not surprisingly, members of Congress from these places have talked about it the most in Congress.

A review of House and Senate floor remarks using the Capitol Words tool over at the Sunlight Foundation, in fact, shows three of the top four marijuana-mentioners over the past five years come from these five locales.

One represents the District of Columbia — Del. Eleanor Holmes Norton (D), who since 2010 has mentioned pot more than any other member. The other two, meanwhile, represent Oregon and Colorado — or more specifically, Portland and Boulder. Because, of course.

Rounding out the top 10 are two Iowans: Republican Rep. Steve King and Sen. Charles Grassley (we'll allow you to make your own joke about his last name), two Californians (though neither from where you might think), a member from Las Vegas, one from Memphis and another Oregonian, Sen. Ron Wyden (D).

The other interesting stat here: While marijuana over the past 19 years has been mentioned much more by Republicans, over the past five years, about three-fourths of mentions have come from Democrats.
